Description:
REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit under 35 USC § 119 of JP Patent Applications JP 2021-007533 filed Jan. 20, 2021 and JP 2021-185791 filed Nov. 15, 2021, the entire disclosure of which is incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a glass run which couples to a door of an automobile and includes an extended part with an outer-cabin side surface covered with a decorative film, a coupling structure of the glass run, and a method of manufacturing the glass run. 
       FIG. 11  illustrates a door (front door)  1  of an automobile including a frame  3 , and a door (rear door)  2  of the automobile including a frame  4 .  FIG. 12  illustrates traditional glass runs  10 ,  20  (see, for example, Japanese Unexamined Patent Application Publication No. 08-300953). The glass run  10  is partially covered with a decorative film F, and couples to the frame  3 . The glass run  20  is partially covered with the decorative film F, and couples to the frame  4 . A shaded part in  FIG. 12  indicates a die-molded part. 
     The decorative film F, which partially covers the glass run  10  on the front door  1 , is attached to an outer-cabin side surface of a decorative lip  12 , and is continuously extended to cover an outer-cabin side surface of an extended part  13 . The decorative lip  12  is formed on an outer-cabin side of an installation member  11  of the glass run  10 , and is continuously extended toward a rear part of an automobile body to form the extended part  13 . The extended part  13  extends from a rear end of an upper side on an upper corner part of the front door  1 . 
     In the same manner, the decorative film F, which partially covers the glass run  20  on the rear door  2 , is attached to an outer-cabin side surface of a decorative lip  22 , and is continuously extended to cover an outer-cabin side surface of an extended part  23 . The decorative lip  22  is formed on an outer-cabin side of an installation member  21  of the glass run  20 , and is continuously extended toward a front part of the automobile body to form the extended part  23 . The extended part  23  extends from a front end of an upper side on an upper corner part of the rear door  2 . 
     The glass run  10  couples to the front door  1  and the glass run  20  couples to the rear door  2  with the extended part  13  and the extended part  23  faced each other on a parting portion between the front door  1  and the rear door  2 . 
     This configuration gives an optical illusion that a sash molding on the front door  1  and a sash molding on the rear door  2  are continuous, and improves appearance. 
       FIG. 13  illustrates cross-sectional shapes of the extended parts  13 ,  23 . The extended parts  13 ,  23  are formed by extruding extrusion-molding material alongside of the decorative film F, and then covering an end surface  13   a  of the extended part  13  and an end surface  23   a  of the extended part  23  with the die-molding material. 
     An end surface Fa of the decorative film F is aligned with the end surface  13   a . The end surface Fa is aligned with the end surface  23   a . The decorative films F in  FIG. 13  are provisionally painted in black, but the decorative films F in real products are generally painted in colors other than black. 
     Such glass runs  10 ,  20  known in the art have the problems described below. The extended part  13  has a cover member  14  attached to an end, and the extended part  23  has a cover member  24  attached to an end. The cover members  14 ,  24 , which are faced each other, are colored black and exposed. The cover members  14 ,  24  form two black strips between the front door  1  and the rear door  2  when the doors  1 ,  2  are seen from an exterior of the automobile with the doors  1 ,  2  in closed positions, and degrade appearance. 
     Some glass runs known in the art have caps (illustration omitted), not the cover members  14 ,  24 , fixed on the end surfaces of the extended parts (see, for example, Japanese Unexamined Patent Application Publication No. 2019-112010). Unfortunately, however, the caps form strips between the extended parts and the caps, interrupt continuous appearance of the decorative films F, and degrade appearance. 
     To solve the above problems, it is an object of the present invention to provide glass runs with continuous appearance improved between two adjacent decorative films on outer-cabin sides of the glass runs to allow for better appearance, a coupling structure of the glass runs, and a method of manufacturing the glass runs. 
     SUMMARY OF THE INVENTION 
     To achieve the above object, an aspect of the present invention provides a glass run ( 50 ,  70 ) for a door ( 1 ,  2 ) of an automobile, for guiding a door glass (G) in a frame ( 3 ,  4 ). 
     The glass run ( 50 ,  70 ) includes an installation member ( 51 ,  71 ), a body ( 52 ,  72 ), an extended part ( 53 ,  73 ), and a decorative film (F). The installation member ( 51 ,  71 ) couples to the frame ( 3 ,  4 ). The body ( 52 ,  72 ) forms a channel. The extended part ( 53 ,  73 ) is formed by extending an outer-cabin side of the installation member ( 51 ,  71 ) in a direction away from the door ( 1 ,  2 ) from an end of an upper side of the door ( 1 ,  2 ). The decorative film (F) is bent on an end of the extended part ( 53 ,  73 ) toward an inner-cabin side of the extended part ( 53 ,  73 ) from an outer-cabin side to cover an end surface ( 53   c ,  73   c ) of the extended part ( 53 ,  73 ). 
     In addition, according to an aspect of the present invention, the decorative film (F) has an upper end (F 1 ) and a lower end (F 2 ) bent to incline toward an interior of the automobile from an exterior or form arcs. 
     Also, part of the upper end (F 1 ) and part of the lower end (F 2 ) of the decorative film (F) are removed by predetermined distance (FL 1 , FL 2 ) (width in a front and rear direction of cut-off parts (FK 1 , FK 2 ) of the decorative film (F)) from the end surface ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ) to reduce a width (FW 1 , FW 2 ) in an upper and lower direction of a remainder part of the decorative film (F). 
     In addition, according to an aspect of the present invention, first ends of the cut-off parts (FK 1 , FK 2 ) of the upper end (F 1 ) and the lower end (F 2 ) of the decorative film (F) are chamfered and formed into curved corner parts. The first ends are opposite second ends of the cut-off parts (FK 1 , FK 2 ). The second ends are closer to the end surface ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ). 
     In addition, according to an aspect of the present invention, the glass run ( 50 ,  70 ) further includes a base ( 90 ) which attaches the decorative film (F) to the extended part ( 53 ,  73 ). The base ( 90 ) is composed of hard resin higher in rigidity than the extended part ( 53 ,  73 ). The base alongside of the decorative film is bent on the end of the extended part ( 53 ,  73 ) toward the interior of the automobile from the exterior to cover the end surface ( 53   c ,  73   c ) of the extended part ( 53 ,  73 ). 
     In addition, according to an aspect of the present invention, the glass run ( 50 ,  70 ) further includes an insert panel ( 91 ) embedded between the base ( 90 ), which is bent, and the end surface ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ). 
     In addition, an aspect of the present invention provides a coupling structure of the glass run ( 50 ) to a front door ( 1 ) and the glass run ( 70 ) to a rear door ( 2 ). The structure includes a first extended part ( 53 ) of the glass run ( 50 ) and a second extended part ( 73 ) of the glass run ( 70 ). The first extended part ( 53 ) is extended toward a rear part of an automobile body from a rear end of an upper side of the front door ( 1 ). The second extended part ( 73 ) is extended toward a front part of the automobile body from a front end of an upper side of the rear door ( 2 ). The first extended part ( 53 ) and the second extended part ( 73 ) are faced each other on a parting portion between the front door ( 1 ) and the rear door ( 2 ). 
     In addition, an aspect of the present invention provides a method of manufacturing a glass run ( 50 ,  70 ) for a door ( 1 ,  2 ) of an automobile, for guiding a door glass (G) in a frame ( 3 ,  4 ). The glass run ( 50 ,  70 ) includes an installation member ( 51 ,  71 ), a body ( 52 ,  72 ), an extended part ( 53 ,  73 ), a decorative film (F), and a base ( 90 ). The installation member ( 51 ,  71 ) couples to the frame ( 3 ,  4 ). The body ( 52 ,  72 ) forms a channel. The extended part ( 53 ,  73 ) is formed by extending an outer-cabin side of the installation member ( 51 ,  71 ) in a direction away from the door ( 1 ,  2 ) from an end of an upper side of the door ( 1 ,  2 ). The base ( 90 ) attaches the decorative film (F) to the extended part ( 53 ,  73 ). The base ( 90 ) is composed of hard resin higher in rigidity than the extended part ( 53 ,  73 ). The base ( 90 ) alongside of the decorative film (F) is bent on an end of the extended part ( 53 ,  73 ) toward the interior of the automobile from the exterior to cover an end surface ( 53   c ,  73   c ) of the extended part ( 53 ,  73 ). 
     The method includes: forming the extended part ( 53 ,  73 ), alongside of the base ( 90 ) and the decorative film (F), by extrusion molding; making a first cut (M 1 ) on the extended part ( 53 ,  73 ), the first cut (M 1 ) extending by a predetermined length (L) from the end surface ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ), the first cut (M 1 ) being parallel to the decorative film (F); making a second cut (M 2 ) on the extended part ( 53 ,  73 ), the second cut (M 2 ) extending by a predetermined length (J) toward the exterior of the automobile from the interior; removing a cut-off part (K) as part of the extended part ( 53 ,  73 ) along the first cut (M 1 ) and the second cut (M 2 ); bending a remainder part (Z) of the extended part ( 53 ,  73 ) on an appropriate part of the remainder part (Z) toward the interior of the automobile; and subjecting an end surface (Za) of the remainder part (Z) to die molding to cover the end surface (Za) of the remainder part (Za). 
     In addition, an aspect of the present invention provides a method of manufacturing a glass run ( 50 ,  70 ) for a door ( 1 ,  2 ) of an automobile, for guiding a door glass (G) in a frame ( 3 ,  4 ). The glass run ( 50 ,  70 ) includes an installation member ( 51 ,  71 ), a body ( 52 ,  72 ), an extended part ( 53 ,  73 ), a decorative film (F), and a base ( 90 ). The installation member ( 51 ,  71 ) couples to the frame ( 3 ,  4 ). The body ( 52 ,  72 ) forms a channel. The extended part ( 53 ,  73 ) is formed by extending an outer-cabin side of the installation member ( 51 ,  71 ) in a direction away from the door ( 1 ,  2 ) from an end of an upper side of the door ( 1 ,  2 ). The base ( 90 ) attaches the decorative film (F) to the extended part ( 53 ,  73 ). The base ( 90 ) is composed of hard resin higher in rigidity than the extended part ( 53 ,  73 ). The base ( 90 ) alongside of the decorative film (F) is bent on an end of the extended part ( 53 ,  73 ) toward the interior of the automobile from the exterior to cover an end surface ( 53   c ,  73   c ) of the extended part ( 53 ,  73 ). 
     The method includes: forming the extended part ( 53 ,  73 ), alongside of the base ( 90 ) and the decorative film (F), by extrusion molding; making a first cut (M 1 ) on the extended part ( 53 ,  73 ), the first cut (M 1 ) extending by a predetermined length (L) from the end surface ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ), the first cut (M 1 ) being parallel to the decorative film (F); making a second cut (M 2 ) on the extended part ( 53 ,  73 ), the second cut (M 2 ) extending by a predetermined length (J) toward the exterior of the automobile from the interior; removing a cut-off part (K) as part of the extended part ( 53 ,  73 ) along the first cut (M 1 ) and the second cut (M 2 ); bending a remainder part (Z) of the extended part ( 53 ,  73 ) by a bending distance (S) toward the interior of the automobile, the bending distance (S) being (L) minus (T) (S=L−T), where (L) is a predetermined length and (T) is a distance of straight part; and subjecting an end surface (Za) of the remainder part (Z) to die molding to cover the end surface (Za) of the remainder part (Z). 
     In addition, an aspect of the present invention provides a method of manufacturing a glass run ( 50 ,  70 ) for a door ( 1 ,  2 ) of an automobile, for guiding a door glass (G) in a frame ( 3 ,  4 ). The glass run ( 50 ,  70 ) includes an installation member ( 51 ,  71 ), a body ( 52 ,  72 ), an extended part ( 53 ,  73 ), a decorative film (F), and a base ( 90 ). The installation member ( 51 ,  71 ) couples to the frame ( 3 ,  4 ). The body ( 52 ,  72 ) forms a channel. The extended part ( 53 ,  73 ) is formed by extending an outer-cabin side of the installation member ( 51 ,  71 ) in a direction away from the door ( 1 ,  2 ) from an end of an upper side of the door ( 1 ,  2 ). The decorative film (F) has an upper end (F 1 ) and a lower end (F 2 ) bent to incline toward the interior of the automobile from the exterior or form arcs. The base ( 90 ) attaches the decorative film (F) to the extended part ( 53 ,  73 ). The base ( 90 ) is composed of hard resin higher in rigidity than the extended part ( 53 ,  73 ). The base ( 90 ) alongside of the decorative film (F) is bent on an end of the extended part ( 53 ,  73 ) toward the interior of the automobile from the exterior to cover an end surface ( 53   c ,  73   c ) of the extended part ( 53 ,  73 ). 
     The method includes: forming the extended part ( 53 ,  73 ), alongside of the base ( 90 ) and the decorative film (F), by extrusion molding; making a first cut (M 1 ) on the extended part ( 53 ,  73 ), the first cut (M 1 ) extending by a predetermined length (L) from the end surface ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ), the first cut (M 1 ) being parallel to the decorative film (F); making a second cut (M 2 ) on the extended part ( 53 ,  73 ), the second cut (M 2 ) extending by a predetermined length (J) toward the exterior of the automobile from the interior; removing a cut-off part (K) as part of the extended part ( 53 ,  73 ) along the first cut (M 1 ) and the second cut (M 2 ); making cuts on part of the upper end (F 1 ) and part of the lower end (F 2 ) of the decorative film (F) by a predetermined distance (FL 1 , FL 2 ) (width in a front and rear direction of cut-off parts (FK 1 , FK 2 ) of the decorative film (F)) from the end surface ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ); removing the cut-off parts (FK 1 , FK 2 ) of the decorative film (F) to reduce a width (FW 1 , FW 2 ) in an upper and lower direction of a remainder part (FZ 1 , FZ 2 ) of the decorative film (F); bending the remainder part (FZ 1 , FZ 2 ) of the decorative film (F) subjected to removal of the cut-off parts (FK 1 , FK 2 ) of the decorative film (F) by a bending distance (S) toward the interior of the automobile; and subjecting an end surface (FZ 1   a , FZ 2   a ) of the remainder part (FZ 1 , FZ 2 ) of the decorative film (F) to die molding to cover the end surface (FZ 1   a , FZ 2   a ) of the remainder part (FZ 1 , FZ 2 ). 
     In addition, according to an aspect of the present invention, the method further includes chamfering first ends of the cut-off parts (FK 1 , FK 2 ) of the upper end (F 1 ) and the lower end (F 2 ) of the decorative film (F) to form the first ends into curved corner parts. The first ends are opposite second ends of the cut-off parts (FK 1 , FK 2 ). The second ends are closer to the end surfaces ( 53   a ,  73   a ) of the extended part ( 53 ,  73 ). 
     Symbols in parentheses show constituents or items corresponding to the drawings. 
     According to the present invention, the decorative film attached to the outer-cabin side of the extended part is bent on the end of the extended part toward the inner-cabin side of the extended part from the outer-cabin side to cover the end surface of the extended part. That is, the decorative film is exposed on a surface. The use of the decorative film leads to lower manufacturing cost and weight saving of products as compared with the use of metal moldings. 
     The decorative film exposed on the surface improves continuous appearance between the decorative film attached to the extended part on the front door and the decorative film attached to the extended part on the rear door when the decorative films are faced each other on the parting portion between the front door and the rear door. This allows for better appearance. 
     In other words, although cover members composed of die-molding material form two black strips on the ends of the extended parts of traditional glass runs ( FIG. 13 ), the present invention prevents appearance of the black strips. 
     The present invention is more effective when applied around a center pillar of the automobile, on which the front door and the rear door are faced each other. This is because the center pillar is about level with human eye, and is more conspicuous than any other part. 
     In addition, the decorative film has the upper end and the lower end bent to incline toward the interior of the automobile from the exterior or form arcs. Also, the part of the upper end and the part of the lower end of the decorative film are removed by predetermined distance (FL 1 , FL 2 ) from the end surface of the extended part to reduce the width in the upper and lower direction of the remainder part of the decorative film. This configuration prevents sharp-pointed parts or wrinkles on a bent part of the decorative film when the end of the extended part is bent toward the interior of the automobile from the exterior. 
     In addition, the first ends of the cut-off parts of the upper end and the lower end of the decorative film are chamfered and formed into curved corner parts. The first ends are opposite the second ends of the cut-off parts which are closer to the end surface of the extended part. This configuration further prevent the sharp-pointed parts or wrinkles. 
     In addition, the base composed of hard resin higher in rigidity than the extended part attaches the decorative film to the extended part, and stably supports the decorative film which is thin. This configuration facilitates bending of the decorative film alongside of the base on the end of the extended part toward the interior of the automobile from the exterior, to cover the end surface of the extended part. 
     In addition, the insert panel is embedded between the base which is bent and the end surface of the extended part. This configuration simplifies support and fixing of the base alongside of the decorative film inside the cavity to cover the end surface using the die-molding material. 
     In addition, the method of manufacturing the glass run includes: forming the extended part, alongside of the base and the decorative film, by extrusion molding; making the cut (M 1 ) on the extended part, the cut (M 1 ) extending by the predetermined length (L) from the end surface of the extended part, the cut (M 1 ) being parallel to the decorative film (F); making the cut (M 2 ) on the extended part, the cut (M 2 ) extending by the predetermined length (J) toward the exterior of the automobile from the interior; removing the cut-off part (K) as the part of the extended part along the cut (M 1 ) and the cut (M 2 ); and bending the remainder part (Z) of the extended part on the appropriate part of the remainder part (Z) toward the interior of the automobile. This configuration improves unification and close adherence between the extended part and the base alongside of the decorative film F, as compared with the decorative film and the base which are separately attached to the end of the extended part formed by extrusion molding. 
     In addition, the method includes: bending the remainder part (Z) of the extended part by the bending distance (S), which is (L) minus (T) (S=L−T) where (L) is a predetermined length and (T) is a distance of straight part, toward the interior of the automobile; and subjecting the end surface (Za) of the remainder part (Z) to die molding to cover the end surface (Za). The die-molding material would cover unevenness on the edges of a space if edges of the cut-off part (K) are uneven, and leads to beautiful finishing of the products. 
     In addition, the decorative film has the upper end and the lower end bent to incline toward the interior of the automobile from the exterior or form arcs. The method includes: removing the cut-off part as part of the extended part; making cuts on the part of the upper end and the part of the lower end of the decorative film by the predetermined distance (FL 1 , FL 2 ) (width in the front and rear direction of the cut-off parts of the decorative film) from the end surface of the extended part; removing the cut-off parts of the decorative film to reduce the width in the upper and lower direction of the remainder part of the decorative film; bending the remainder part of the decorative film, subjected to removal of the cut-off parts of the decorative film, by the bending distance (S) toward the interior of the automobile; and subjecting the end surface of the remainder part of the decorative film to die molding to cover the end surface. 
     This configuration prevents sharp-pointed parts or wrinkles on the bent part of the decorative film when the remainder part is bent toward the interior of the automobile from the exterior. 
     In addition, the first ends of the cut-off parts of the upper end and the lower end of the decorative film are chamfered and formed into curved corner parts. The first ends are opposite the second ends of the cut-off parts which are closer to the end surface of the extended part. This configuration further prevent the sharp-pointed parts or wrinkles.

     DETAILED DESCRIPTION 
     Referring to  FIG. 1  to  FIG. 6D , and  FIG. 10 , a glass run according to an embodiment of the present invention will be described. When constituents or items correspond to those in prior arts, the same symbols are used. A shaded part in  FIG. 1  indicates a die-molded part. A decorative film F in  FIG. 1  to  FIG. 6D  is painted in black. 
     A glass run  50  according to the embodiment of the present invention is of so-called “hidden type”. More specifically, as illustrated in  FIGS. 1 to 3  and  FIG. 10 , the glass run  50  couples to a flange  3 A of a frame  3  of a door of an automobile, a front door  1  in the present embodiment, to cover up a part of the frame  3  from an exterior of the automobile. The flange  3 A extends toward the exterior of the automobile. 
     The glass run  50  includes a first extrusion-molded part closer to a roof of an automobile body and a second extrusion-molded part closer to a center pillar (illustration omitted) of the automobile body, and a die-molded part Mo. The die-molded part Mo connects the first extrusion-molded part with the second extrusion-molded part on a corner part closer to a rear end of an upper side of the front door  1 . The glass run  50  guides a door glass G in the frame  3  and includes an installation member  51  and a body  52 . The installation member  51  couples to the flange  3 A. The body  52  forms a channel to receive the door glass G. 
     An outer-cabin side of the installation member  51  is extended toward a rear part of the automobile body with the front door  1  in a closed position, that is in a direction away from the front door  1 , from the rear end of the upper side of the front door  1 , to form an extended part  53 . A decorative film F (bright film in the present embodiment) is attached to an outer-cabin side of the extended part  53  with a base  90  sandwiched between the decorative film F and the extended part  53 . A garnish  81  is attached to a center pillar on an outer-cabin side of the front door  1 , and a garnish  82  is attached to a center pillar on an outer-cabin side of the rear door  2 . 
     As illustrated in  FIG. 2 , the installation member  51  has a substantially U-shaped cross-section, and includes an upper side wall  55 , a lower side wall  56 , and a connecting wall  57 . The upper side wall  55  and the lower side wall  56  extend in an inner-cabin and outer-cabin direction. The connecting wall  57  connects the upper side wall  55  and the lower side wall  56 . The installation member  51  has an anchoring member  58  formed on an inner side to make elastic contact with the flange  3 A. In the present embodiment, the upper side wall  55  has three lip-shaped anchoring members  58  on a lower surface, and the lower side wall  56  has two protrusion-shaped anchoring members  58  on an upper surface. 
     The upper side wall  55  includes a body seal lip  59 , a seal lip  60 , a lip  61 , and a covering lip  62 . The body seal lip  59  extends from a substantial center on an upper surface of the upper side wall  55  and makes elastic contact with a circumferential edge (illustration omitted) of a door opening of the automobile body to seal a gap between the automobile body and the front door  1 . The seal lip  60  and the lip  61  extends from an inner-cabin side end of the upper side wall  55 . The seal lip  60  extends downward toward an interior of the automobile and makes elastic contact with the flange  3 A, and the lip  61  extends upward toward the exterior of the automobile. The covering lip  62  extends from part of the upper surface of the upper side wall  55  closest to the exterior of the automobile and makes contact with and covers an upper surface of the decorative film F, attached to the outer-cabin side of the glass run  50 . A core  63 , which has a substantially U-shaped cross-section, is embedded in the installation member  51  along the upper side wall  55 , the connecting wall  57 , and the lower side wall  56 , to increase rigidity. 
     The body  52  includes the lower side wall  56 , an inner-cabin side wall  64 , and an outer-cabin side wall  65 . The inner-cabin side wall  64  extends downward from an inner-cabin side of the lower side wall  56 . The outer-cabin side wall  65  extends downward from an outer-cabin side of the lower side wall  56 . The lower side wall  56  connects the side walls  64 ,  65  and forms the channel to receive the door glass G. The outer-cabin side wall  65  is continuous with the connecting wall  57 . The outer-cabin side wall  65  and the connecting wall  57 , which are integral with each other, are extended toward the rear part of the automobile body with the front door  1  in the closed position to form the extended part  53  (illustrated in  FIG. 10 ). 
     The body  52  includes an inner lip  66  and an outer lip  67 . The inner lip  66  extends toward the exterior of the automobile from an outer-cabin side surface of an end of the inner-cabin side wall  64 , and is slidably brought into contact with an inner-cabin side surface of the door glass G. The outer lip  67  extends toward the interior of the automobile from an inner-cabin side surface of an end of the outer-cabin side wall  65  and is slidably brought into contact with an outer-cabin side surface of the door glass G. In the present embodiment, the body  52  also includes a glass seal lip  68 . The glass seal lip  68  extends from a lower surface of the lower side wall  56  and makes elastic contact with an end of the door glass G. Alternatively, the glass seal lip  68  may be omitted. 
       FIG. 3  illustrates the installation member  51  and the body  52  on the extended part  53 , formed by extrusion molding, in vertical cross section. The installation member  51  and the body  52  on the extended part  53  are prepared by cutting out and removing the inner-cabin side wall  64 , the inner lip  66 , the outer lip  67 , and the glass seal lip  68  from an extruded shape in vertical cross section of the first extrusion-molded part illustrated in  FIG. 2 . 
     Part of a cover member  54  to be discussed later is connected with the installation member  51  or the body  52  by die molding (details of configuration omitted), and may be unified. 
     In the same manner as the glass run  50 , which couples to the front door  1 , a glass run  70  couples to the rear door  2 . The glass run  70  has the same configuration (details omitted) as the glass run  50 . The extended part  53  is extended toward the rear part of the automobile body, that is in the direction away from the rear end of the upper side of the front door  1 . An extended part  73  of the glass run  70  on the rear door  2  is extended toward a front part of the automobile body, that is in the direction away from a front end of an upper side of the rear door  2 . The glass run  50  couples to the frame  3  and the glass run  70  couples to a frame  4  of the rear door  2  with the extended part  53  and the extended part  73  faced each other on a parting portion between the front door  1  and the rear door  2 . 
     Examples of the material of the glass runs  50 ,  70  include EPDM rubber and thermoplastic elastomer (TPE) such TPO, TPS. Also, the material may be foamed or solid. 
     In this embodiment, the glass runs  50 ,  70  include solid material composed of TPE. 
     The base  90  is composed of hard resin higher in rigidity than the extended parts  53 ,  73 , and has a thickness of not more than 2 mm (preferably not more than 1 mm). Also, the base  90  has a flexural modulus of elasticity that falls within a range of 850 to 4500 MPa, which is higher than the glass runs  50 ,  70 . 
     Examples of the material of the base  90  include polypropylene with talc or glass fiber mixed. Changing the amount of talc or glass fiber to be mixed secures the flexural modulus of elasticity of the base  90  within the above-mentioned range. In this embodiment, it is only required that the base  90  has the flexural modulus of elasticity that falls within the above-mentioned range. In some embodiments, the base  90  is composed of material other than polypropylene with talc or glass. 
     As illustrated in  FIGS. 2 and 3 , the decorative film F has an upper end F 1  and a lower end F 2  bent to incline toward the interior of the automobile from the exterior or form arcs (alternatively, the decorative film F may be straight-linear in an upper and lower direction without bending the upper end F 1  and the lower end F 2 ). In some embodiments, as illustrated in  FIG. 20 , the upper end F 1  and the lower end F 2  are bent to form the arcs and partially covered with extrusion-molding material, in a different manner from  FIG. 3 . 
     As illustrated in  FIGS. 4 and 5 , the decorative film F alongside of the base  90  is bent on the end of the extended part  53 , to make a right-angled turn toward the interior of the automobile from the exterior, and cover an end surface  53   c  of the extended part  53 . The end surface  53   c  appears when part of the extended part  53  is removed. In the same manner, the decorative film F alongside of the base  90  is bent on the end of the extended part  73 , to make the right-angled turn toward the interior of the automobile, and cover an end surface  73   c  of the extended part  73 . The end surface  73   c  appears when part of the extended part  73  is removed. 
     The cover member  54  fills up a space between the end surface  53   c  and the base  90  alongside of the decorative film F, which are bent. The cover member  74  fills up a space between the end surface  73   c  and the base  90  alongside of the decorative film F, which are bent. The cover members  54 ,  74  are composed of die-molding material.  FIG. 4  also illustrates a core N for use on a cavity for die molding for better understanding about how the components are arranged. 
     Examples of the decorative film F include thin films and film materials composed of elaborately designed layers with adhesive or a bonding layer on rear surfaces. 
     More specifically, the examples include thin films of stainless steel, metallised films, synthetic resin multilayer films, films decorated with patterns, and films painted in desired colors. 
     In the present embodiment, it is only required that the adhesive or the bonding layer adheres to or bonds to the base  90 . In some embodiments, the adhesive or the bonding layer is accompanied by a primer to be sandwiched between the base  90  and the adhesive or the bonding layer. 
     Referring to  FIGS. 6A to 6D , a method according to an embodiment of the present invention of manufacturing the extended parts  53 ,  73  will be described. The extended part  53  extends from the corner part closer to the rear end of the upper side of the front door  1  on which the die molded part Mo connects the first extrusion-molded part with the second-extrusion molded part to form the glass run  50 . The extended part  73  extends from the corner part closer to the front end of the upper side of the rear door  2  on which the die molded part Mo connects the first extrusion-molded part with the second-extrusion molded part to form the glass run  70 . 
     The base  90  and the decorative film F, alongside of the installation member  51  and the body  52 , are formed by extrusion molding ( FIG. 6A ). In the same manner, the base  90  and the decorative film F, alongside of the installation member  71  and the body  72 , are formed by extrusion molding. 
     Part of the extended part  53 , except for the base  90  and the decorative film F, is cut by predetermined length (L) from the end using cutting tools such as cutters and rotary blades, such that at least the base  90  and the decorative film F remain untouched ( FIG. 6B ). In the same manner, part of the extended part  73 , except for the base  90  and the decorative film F, is cut by the predetermined length (L) from the end using cutting tools such as cutters and rotary blades, such that at least the base  90  and the decorative film F remain untouched. 
     More specifically, as illustrated in  FIG. 6A , a first cut M 1  and a second cut M 2  are made on the extended part  53 . The cut M 1  extends by the predetermined length (L) from the end surface  53   a  of the extended part  53 , and is parallel to the decorative film F. The cut M 2  extends by a predetermined length (J) toward the exterior of the automobile from the interior. In the same manner, the cut M 1  and the cut M 2  are made on the extended part  73 . The cut M 1  extends by the predetermined length (L) from the end surface  73   a  of the extended part  73 , and is parallel to the decorative film F. The cut M 2  extends by the predetermined length (J) toward the exterior of the automobile from the interior. 
     As illustrated in  FIG. 6B , the cuts M 1 , M 2  allow for easy removal of cut-off part K. The cut-off part K forms part of the extended part  53 . In the same manner, the cut-off part K forms part of the extended part  73 . 
     When the cut-off part K is removed from the extended part  53 , the cut M 1  forms a side surface  53   b  and the cut M 2  forms the end surface  53   c . In the same manner, when the cut-off part K is removed from the extended part  73 , the cut M 1  forms a side surface  73   b  and the cut M 2  forms the end surface  73   c . The cuts M 1  are preferably made prior to the cuts M 2 , but the order is not limited. Either of the cuts M 1 , M 2  may be formed first, or the cuts M 1 , M 2  may be formed simultaneously. In making the cuts M 1 , only the bases  90  and the decorative films F may remain untouched. If the base  90  is thin as illustrated in  FIG. 3  or a boundary line is curved, not linear, between the base  90  and the connecting wall  57  or the outer-cabin side wall  65 , part of the connecting wall  57  or the outer-cabin side wall  65  on the extended part  53  may remain on the base  90  in making the cuts M 1 . 
     The base  90  stably supports the decorative film F, which is thin, on the end surface  53   a . In the same manner, the base  90  stably supports the decorative film F, which is thin, on the end surface  73   a . This configuration facilitates the removal of only the cut-off parts K from the extended part  53  and the extended part  73 . 
     When the cut-off part K is removed from the extended part  53 , a remainder part Z remains. The remainder part Z includes the decorative film F and the base  90 . In the same manner, when the cut-off part K is removed from the extended part  73 , the remainder part Z remains. The remainder part Z includes the decorative film F and the base  90 . The remainder parts Z are bent by a bending distance (S) toward the interior of the automobile ( FIGS. 6B, 6C, 6D ). The bending distance (S) is (L) minus (T) (S=L−T), where (L) is a predetermined length and (T) is a distance of straight part. 
     The bases  90  stably support the decorative films F, which are thin. This configuration facilitates bending of the decorative films F alongside of the bases  90  toward the interior of the automobile from the exterior. 
     The decorative films F alongside of the bases  90  are bent around points P toward the interior of the automobile. The points P are within the bending distance (S) from end surfaces  90   a  of the bases  90  ( FIG. 6C ). 
     In the present embodiment, a cut M 3  is made to extend upward toward an outer side to the point P from the side surface  53   b , which appears when the cut-off part K is removed ( FIG. 6C ), and form a concave part having a triangular shape such that the cut M 3  is closed when the base  90  is in the bent position ( FIG. 6D ). In the same manner, the cut M 3  is made to extend upward toward the outer side to the point P from side surface  73   b , which appears when the cut-off part K is removed, and form the concave part having the triangular shape such that the cut M 3  is closed when the base  90  is in the bent position. In some embodiments, the cuts M 3  are linear or omitted. Alternatively, the remainder parts Z, which remain when the cut-off parts K are removed and include the decorative films F and the bases  90 , may be bent on appropriate parts toward the interior of the automobile. 
     In some embodiments, as illustrated in  FIG. 19A , the cuts M 3  are cuts (concave parts) M 4 , having quadrilateral shapes which are made, for example, by cutlery or hot plates. Alternatively, as illustrated in  FIG. 19B , the cuts M 3  may be cuts (concave parts) M 5  having quadrilateral shapes which are made, for example, by the cutlery or hot plates, to remove parts of the bases  90  as well. Alternatively, as illustrated in  FIG. 19C , the cuts M 3  may be cuts (concave parts) M 6  having quadrilateral shapes which are made, for example, by the cutlery, to leave the bases  90  untouched and without the distance T of the straight part (distance T is zero). 
     Next, as illustrated in  FIGS. 5 to 6D , the cover member  54 , composed of the die-molding material, is formed by die molding on a space (R). The space (R) covers an end (Za) of the remainder part Z, which includes the bending shape of the decorative film F and the base  90 , and the end surface  53   c , which appears when part of the extended part  53  is removed. In the same manner, the cover member  74 , composed of the die-molding material, is formed by die molding on the space (R). The space (R) covers the end (Za) of the remainder part Z, which includes the bending shape of the decorative film F and the base  90 , and the end surface  73   c , which appears when part of the extended part  73  is removed. 
     The die-molding material would cover unevenness on the edges of the spaces (R) if the edges of the cut-off parts K are uneven, and leads to beautiful finishing of the products. 
     In the present embodiment, the cover member  54  is aligned with the surface of the decorative film F, which is bent, and the cover member  54 , colored black, is not visible when the door  1  is seen from the exterior of the automobile. In the same manner, the cover member  74  is aligned with the surface of the decorative film F, which is bent, and the cover member  74 , colored black, is not visible when the door  2  is seen from the exterior of the automobile. 
     The decorative film F on the outer-cabin side of the extended part  53  of the glass run  50  according to the embodiment is bent on the end of the extended part  53  toward the interior of the automobile, to cover the end surface  53   c . In the same manner, the decorative film F on the outer-cabin side of the extended part  73  of the glass run  70  according to the embodiment is bent on the end of the extended part  73  toward the interior of the automobile, to cover the end surface  73   c . This configuration allows for exposure of the decorative films F on the surfaces of the extended parts  53 ,  73 . 
     This configuration improves a continuous appearance between the decorative film F on the front door  1  and the decorative film F on the rear door  2  on the parting portion between the front door  1  and the rear door  2 , to allow for better appearance. 
     The use of the decorative films F leads to lower manufacturing cost and weight saving as compared with the use of metal moldings on the products having the same appearance. 
     In the present embodiment, as illustrated in  FIGS. 5 to 6D , at least the decorative films F and the bases  90  are bent to make the right-angled turns toward the interior of the automobile. The angle of the turns is not limited. In some embodiments, as illustrated in  FIG. 7 , the decorative film F and the base  90  are bent and folded to make acute-angled turns, not right-angled turns, toward the front part on the front door  1 . In the same manner, the decorative film F and the base  90  are bent and folded to make acute-angled turns, not right-angled turns, toward the rear part on the rear door  2 . In this modification also, the cover member  54  is formed by die molding on the space (R), which covers the bent remainder part and the end surface  53   c , and the cover member  74  is formed by die molding on the space (R), which covers the bent remainder part and the end surface  73   c . The end surface  53   c  is part of the extended part  53  (remainder of the extended part  53  after removal of cut-off part K) and appears when the cut-off part K is removed. The end surface  73   c  is part of the extended part  73  (remainder of the extended part  73  after removal of cut-off part K) and appears when the cut-off part K is removed. 
     In this modification, the cover member  54  is not aligned with the surface of the decorative film F, and the die-molding material clasps the decorative film F and the base  90 , which are bent. In the same manner, the cover member  74  is not aligned with the surface of the decorative film F, and the die-molding material clasps the decorative film F and the base  90 , which are bent. This configuration increases close adherence between the die-molding material and the base  90  alongside of the decorative film F, and improves bond strength. 
     In the present embodiment, the die-molding material is poured into the spaces (R). The space (R) covers the decorative film F and the base  90 , which are bent, and the end surface  53   c . In the same manner, the space (R) covers the decorative film F and the base  90 , which are bent, and the end surface  73   c . The configuration of the space (R) is not limited. In some embodiments, as illustrated in  FIG. 8 , an insert panel  91  is inserted between the end surface  53   c  and the base  90  alongside of the decorative film F, which are bent. The insert panel  91  has a rectangular-shaped cross section. In the same manner, the insert panel  91  is inserted between the end surface  73   c  and the base  90  alongside of the decorative film F, which are bent. In this modification, the space (R) covers the insert panel  91  as well as the end (Za) of the remainder part Z and the end surface  53   c , and is subjected to die molding. In the same manner, the space (R) covers the insert panel  91  as well as the end (Za) of the remainder part Z and the end surface  73   c , and is subjected to die molding. 
     In some embodiments, the insert panel  91  is bonded to the base  90  of the remainder part (Z) or the end surface  53   c  for unification, if necessary, prior to the die molding by cavity. In the same manner, the insert panel  91  is bonded to the base  90  of the remainder part (Z) or the end surface  73   c.    
     In this modification, the cover member  54  may cover the outer side of the decorative film F on the base  90 , which are bent, to hold the decorative film F and the base  90  with the insert panel  91 . In the same manner, the cover member  74  may cover the outer side of the decorative film F on the base  90 , which are bent, to hold the decorative film F and the base  90  with the insert panel  91 . 
     In this modification, the insert panels  91  are inserted in the spaces (R) first, and the spaces (R) are subjected to die molding next. The spaces (R) cover the insert panels  91  as well as lower ends of the decorative films F and the bases  90 , which are bent. This configuration simplifies support and fixing of the bases  90  alongside of the decorative films F inside the cavity (illustration omitted) for the die molding, and improves precision in the shape of the die-molded parts. In some embodiments, an area of the insert panel  91  is smaller than an area by which the decorative film F and the base  90  are bent (illustration omitted). This configuration increases adhesive areas between the base  90  and the cover member  54  and between the base  90  and the cover member  74 , to further improve bond strength. 
     In some embodiments, as illustrated in  FIG. 9 , the core N for use on the cavity, not the insert panel  91  illustrated in  FIG. 8 , directly supports the die-molding material to form the cover members  54 ,  74  by die molding. 
     In the present embodiment, as illustrated in  FIG. 6B , the cut-off parts K as parts of the extended parts  53 ,  73  are removed along the cuts M 1 , M 2  first, and then, the remainder parts (Z) are bent by the bending distance (S), which is (L) minus (T) (S=L−T) where (L) is a predetermined length and (T) is a distance of straight part, toward the interior of the automobile. The removal is not limited to the cut-off parts K. In some embodiments, as illustrated in  FIG. 15 , cut-off parts FK 1  of the decorative films F are removed from the upper ends F 1  and the lower ends F 2  of the decorative films F after removal of the cut-off parts K, and then, remainder parts (FZ 1 ) are bent toward the interior of the automobile. 
     This configuration prevents the sharp-pointed parts V illustrated in  FIG. 14  or wrinkles on the upper ends F 1  and the lower ends F 2  of the decorative films F. The upper ends F 1  and the lower ends F 2 , which are bent to incline toward the interior of the automobile or form arcs in vertical cross section, can cause the sharp-pointed parts V or wrinkles when the remainder parts (Z) of the extended parts  53 ,  73  are bent toward the interior of the automobile from the exterior and parts of the remainder parts (Z) on inner sides of the bent parts have nowhere to go due to perimeter difference. 
     To prevent the sharp-pointed parts V or wrinkles, the cut-off part K as the part of the extended parts  53  is removed first as illustrated in  FIG. 6B , and then, the parts of the upper end F 1  and the lower end F 2  of the decorative film F are removed by predetermined distance FL 1  (width in a front and rear direction of the cut-off parts FK 1  of the decorative film F) from the end surface  53   a  as illustrated in  FIG. 15 , to reduce width FW 1  in an upper and lower direction of remainder part of the decorative film F. A shaded part in  FIG. 15  indicates the cut-off parts FK 1  of the decorative films F. In the same manner, the cut-off part K as the part of the extended part  73  is removed first as illustrated in  FIG. 6B , and then, the parts of the upper end F 1  and the lower end F 2  of the decorative film F are removed by predetermined distance FL 1  (width in the front and rear direction of the cut-off parts FK 1  of the decorative films F) from the end surface  73   a  as illustrated in  FIG. 15 , to reduce the width FW 1  in the upper and lower direction of the remainder part of the decorative film F. 
       FIG. 16  illustrates a manufacturing process in which the remainder part (FZ 1 ) of the extended part  53  is bent toward the interior of the automobile along a crease X 1  indicated by a dotted line in  FIG. 15 . In the same manner, the remainder part (FZ 1 ) of the extended part  73  is bent toward the interior of the automobile along the crease X 1 .  FIG. 17  illustrates a manufacturing process, following the process illustrated in  FIG. 16 , in which the cover member  54 , composed of die-molding material, is formed by die molding. In the same manner, the cover member  74 , composed of die-molding material, is formed by die molding. 
     The crease X 1  inclines in a manner that a lower part approaches the front part of the automobile body. A direction in which the crease X 1  inclines is not limited, and may be changed depending on the design of the automobile. In some embodiments, the crease X 1  inclines in the same direction as  FIG. 15  when the glass run couples to a rear upper end of the front door or a front upper end of the rear door. 
     In some embodiments, the crease X 1  does not incline due to the design of the automobile. 
     In some embodiments, as illustrated in  FIG. 6C , the cuts M 3  are made on the bases  90  to extend upward toward the outer side to the points P and form the concave parts having triangular shapes. Alternatively, the cuts M 3  may be linear or omitted. 
     In some embodiments, the cuts (concave parts) M 4  illustrated in  FIG. 19A , the cuts (concave parts) M 5  illustrated in  FIG. 19B , and the cuts (concave parts) M 6  illustrated in  FIG. 19C  are made instead of the cuts M 3  illustrated in  FIG. 6C . 
     In removing the cut-off parts FK 1 , as illustrated in  FIG. 15 , first ends of the cut-off parts FK 1  are chamfered (chamfers FK 1   a ) and formed into curved corner parts, to further prevent the sharp-pointed parts V or wrinkles. The first ends are opposite second ends of the cut-off parts FK 1  closer to the end surfaces  53   a ,  73   a.    
     In some embodiments, the chamfers FK 1   a  start around where the cut-off parts FK 1  intersect the crease X 1 . Alternatively, the chamfers FK 1   a  may start from where the cut-off parts FK 1  intersect the crease X 1 . 
     In some embodiments, the extended parts  53 ,  73  may also be subjected to thermal compression molding to minimize the cut-off parts FK 1 . Thermal compression molding prevents the extended parts  53 ,  73  to be subjected to bending from returning to the original shapes. 
     In some embodiments, the cut-off parts FK 1  illustrated in  FIG. 15  are cut-off parts FK 2  of the decorative films F illustrated in  FIG. 18 . 
     As illustrated in  FIG. 15 , the crease X 1  is preferably close to radius curvature ends of the chamfers FK 1   a . If the crease X 1  is on a straight part (closer to an end surface FZ 1   a  of the remainder part FZ 1  than the radius curvature ends), the die-molded parts colored black as the cover members  54 ,  74  to fill up the chamfers FK 1   a  are visible over a wider range from the exterior of the automobile. As illustrated in  FIG. 18 , a crease X 2  is preferably close to radius curvature ends of chamfers FK 2   a . If the crease X 2  is on a straight part (closer to an end surface FZ 2   a  of the remainder part FZ 2  than the radius curvature ends), the die-molded parts colored black as the cover members  54 ,  74  to fill up the chamfers FK 2   a  are visible over a wider range from the exterior of the automobile. This degrades appearance of the automobile and is not favorable. If the crease X 1  is not closer to the end surface FZ 1   a  than the radius curvature ends (closer to the front part of the automobile body than the radius curvature ends), more parts of the remainder parts FZ 1  on the inner sides of the bent parts overlap. If the crease X 2  is not closer to end surface FZ 2   a  than the radius curvature ends (closer to the front part of the automobile body than the radius curvature ends), more parts of the remainder parts FZ 2  on the inner sides of the bent parts overlap. This enlarges the sharp-pointed parts V or wrinkles, degrades appearance of the glass runs, and is not favorable. 
     As compared with the cut-off parts FK 1 , upper ends and lower ends of cut-off parts FK 2  of the decorative films F are inclined to approach the center of the decorative films F toward the end surfaces FZ 2   a . In addition, width FW 2  in an upper and lower direction of remainder parts of the decorative films F is shorter than the width FW 1 , and predetermined distance FL 2  (width in a front and rear direction of the cut-off parts FK 2  of the decorative films F) is shorter than the predetermined distance FL 1 . In addition, first ends of the cut-off parts FK 2  are chamfered (chamfers FK 2   a ) and formed into curved corner parts, and the chamfers FK 2   a  are smaller than the chamfers FK 1   a . The first ends are opposite second ends of the cut-off parts FK 2  closer to the end surfaces  53   a ,  73   a.    
     In some embodiments, the chamfers FK 2   a  start around where the cut-off parts FK 2  intersect the crease X 2 . Alternatively, the chamfers FK 2   a  may start from where the cut-off parts FK 2  intersect the crease X 2 . 
     As illustrated in  FIGS. 16 and 17 , the die-molded parts colored black as the cover members  54 ,  74  to fill up the chamfers FK 1   a  are visible over a narrower range from the exterior of the automobile. This improves appearance of the automobile. In addition, the width FW 2 , which is shorter than the width FW 1 , decreases the parts of the remainder parts (Z) on inner sides of the bent parts to overlap, decreases the sharp-pointed parts V or wrinkles, and improves appearance of the glass runs. 
     In the present embodiment, the base  90  and the decorative film F, alongside of the installation member  51  and the body  52 , are formed by extrusion molding first, and the part of the extended part  53  is removed next. In the same manner, the base  90  and the decorative film F, alongside of the installation member  71  and the body  72 , are formed by extrusion molding first, and the part of the extended part  73  is removed next. The configuration of the glass runs  50 ,  70  is not limited. In some embodiments, the first extrusion molded parts do not include the base  90  on the outer-cabin side of the connecting walls  57 ,  77  or the outer-cabin side wall  65 . The die molded part Mo connects the first extrusion molded part without the base  90  with the second extrusion molded part. The decorative film F is separately attached to the outer-cabin side of the glass run  50 , and is bent on the end of the extended part  53  toward the interior of the automobile from the exterior to cover the end of the extended part  53  where the die-molding material covers the end surface  53   a . In the same manner, the decorative film F is separately attached to the outer-cabin side of the glass run  70 , and is bent on the end of the extended part  73  toward the interior of the automobile from the exterior to cover the end of the extended part  73  where the die-molding material covers the end surface  73   a.    
     In the present embodiment, the glass runs  50 ,  70  are of so-called “hidden type”. The glass run  50  couples to the frame  3  of the front door  1 , to cover up the frame  3  from the exterior of the automobile. The decorative film F covers the extended part  53 . The glass run  70  couples to the frame  4  of the rear door  2 , to cover up the frame  4  from the exterior of the automobile. The decorative film F covers the extended part  73 . The glass run is not limited to the “hidden type”. In some embodiments, the glass run has the configuration illustrated in  FIG. 12 . In this modification, an installation member  11  couples to the frame from a lower part. The decorative film F is attached to an extended part  13  of a decorative lip  12 . In the same manner, the decorative film F is attached to an extended parts  23  of a decorative lip  22 . The decorative lips  12 ,  22  are closer to the exterior of the automobile than the installation member  11 . 
     In the present embodiment, as illustrated in  FIG. 5  and  FIG. 10 , the extended part  53  and the extended part  73  are faced each other on the parting portion between the front door  1  and the rear door  2 . The use of the extended part is not limited to the parting portion. In some embodiments, the extended part is used where two adjacent extended parts are not faced each other, including a die-molded part on a front part of the front door  1  and a die-molded part on a rear part of the rear door  2 . 
     In the present embodiment, as illustrated in  FIG. 5  and  FIG. 10 , the extended part  53  on the front door  1  and the extended part  73  on the rear door  2  are closer to the parting portion than the second extrusion molded parts. The positions of the extended parts  53 ,  73  are not limited. In some embodiments, the extended parts  53 ,  73  are aligned with the second extrusion molded parts.
