Description:
BACKGROUND OF THE INVENTION 
     The invention relates to an assembled component for a motor vehicle, in particular for a fixed or movable window, in particular a sash window of a motor vehicle, with a lower flitch, an upper flitch, and an intercalation between the lower flitch and the upper flitch. The assembled component can also be used for other parts of a motor vehicle, in particular for a fixed or movable plate or another part of the body of a motor vehicle. 
     German Patent DE 19916619 A1 discloses an assembled component comprised of three individual pieces, namely an upper piece made according to a spray-cast method for plastics, a lower piece made of plastic, and a reinforcement piece designed as a piece of metal sheet positioned between the upper piece and the lower piece. In order to compensate for heat expansion and component tolerances, profile elements made of elastic material are put to work at the connection points between the individual pieces. 
     SUMMARY OF THE INVENTION 
     The task of the invention is to propose an improved assembled component of the type indicated at the start. 
     This task is solved according to the invention by having the lower flitch and the upper flitch be connected to one another at joining points. 
     Advantageous further developments are described herein. 
     The lower flitch and the upper flitch may be adhered and/or bonded together. This achieves increased stability of the assembled component. The arrangement is preferably done in such a way that the intercalation is held fixed by non-positive and/or positive locking, which can further increase the stability of the assembled component. It is advantageous when the upper flitch and the lower flitch are connected to one another by vibration welding and/or friction welding. 
     The lower flitch and/or the upper flitch may be ribbed. The ribs can be lengthwise and/or diagonal or slanted and/or crosswise ribs. 
     It is advantageous when the joining points are located on the peripheral edges of the lower flitch and upper flitch and/or on the ribs. The joining points can be located near the middle of the ribs and/or at the ends of the ribs. In particular, the ribs can have rises, with the joining points being provided at their tips. 
     Another advantageous further development is characterized in that the intercalation has perforations. The perforations are preferably designed as slits. It is advantageous when the perforations or slits run lengthwise along the assembled component. This can help to reduce internal stresses that may arise due to temperature fluctuations. In temperature fluctuations, the changes in the length of the upper flitch and lower flitch are greatest in the lengthwise direction. Due to the lengthwise perforations or slits, the lengthwise expansions of the upper flitch and lower flitch are decoupled from the adhesion of the intercalation to the window. The upper flitch and lower flitch can extend lengthwise without exerting any stresses thereby on the adhesion of the intercalation to the window. 
     Another advantageous further development is characterized in that the perforations or slits are penetrated by joining points, or rises at which joining points are located. In particular, the rises can be rises of the ribs, or rises that are provided on ribs. 
     Another advantageous further development is characterized in that locating faces are provided at one or more perforations or slits and/or at one or more joining points or rises. This can provide for a definite positioning between the individual pieces of the assembled component, especially between the intercalation and the lower flitch and/or the upper flitch. 
     According to another advantageous further development, expansion gaps are provided at one or more perforations or slits and/or at one or more joining points or rises. In particular, this makes it possible to compensate for differences in length due to differing heat expansions of the individual pieces of the assembled component. It is especially advantageous when two locating faces are provided between two adjacent perforations or slits and at the corresponding joining points or rises and when expansion gaps are provided at the other perforations or slits and joining points or rises. In this way, a definite positioning of the parts of the assembled component is attained, preferably near the middle of the assembled component. The changes in length produced by the differing heat expansions are able to be compensated for at the expansion gaps that are also present. 
     It is advantageous when the intercalation has a bend. If the intercalation is designed as a piece of metal sheet, the bend can be produced as a fold. The bend serves preferably as a joint, in particular as an adhesion point, for a window or sash window of a motor vehicle or for a catch that is connected or connectable to the window or sash window of the motor vehicle. 
     It is advantageous when one or more catches are provided that are connectable or connected to the assembled component. Preferably the catch(es) can be connected to the component in detachable fashion. Preferably the catch(es) can be inserted or snapped into the assembled component. The catch is preferably connectable or connected, especially adherable or adhering, to the body of a motor vehicle. It can form a joining point with the window or sash window. 
     The upper flitch and/or the lower flitch may have one or more guide tracks, especially guide grooves, for a sash window of a motor vehicle. 
     It is advantageous when one or more cleaning holes are provided in the guide tracks or guide grooves. In this way, the guide tracks or guide grooves can be self-cleaning.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIG. 1  shows a part of a body  1  of a motor vehicle, into which a window  2  is inserted, in which a movable window  3  is located. Fixed window  2  has a guide track  4  at its upper area and at its lower area, and catchers  5  of these guide tracks are firmly adhered to fixed window  2 . Guide track  4  shown in  FIG. 1  runs horizontally. In other applications, guide track  4  may run diagonally. 
     As shown in  FIG. 2 , the assembled component, namely guide track  4 , is comprised of a lower flitch  6  made of plastic, an upper flitch  7  made of plastic, and an intercalation  8  made of steel or steel sheet that is situated between lower flitch  6  and upper flitch  7  in the assembled state. As can be seen in  FIG. 2 , lower flitch  6  has ribs on its side that faces upper flitch  7 , namely lengthwise ribs  9 ,  9 ′ and diagonal ribs  10  that run in a zig-zag pattern. 
     Lengthwise rib  9  has six rises  11 , each of which penetrates a corresponding lengthwise slit  12  of intercalation  8 . Near the ends of lengthwise rib  9 ′, which runs parallel to and is spaced at an interval from lengthwise rib  9 , two additional rises  13  are provided that penetrate corresponding additional lengthwise slits  14  in intercalation  8 . The upper tips or tip areas of rises  11  and additional rises  13  form joining points  15  at which lower flitch  6  and upper flitch  7  are connected to one another, namely by vibration welding. Additional joining points  15 ′ are formed by the peripheral edges of lower flitch  6  and upper flitch  7 . Lower flitch  6  and upper flitch  7  are also connected to one another, namely vibration welded, at these joining points  15 ′. 
     Intercalation  8  has a bend  16 , that is connected to the flat main surface  17  of intercalation  8  via a crimp  18 . Main surface  17 , crimp  18  and bend  16  are produced by bending a steel sheet. Flat main surface  17  runs down the middle between lower flitch  6  and upper flitch  7 . Crimp  18  is provided on the side of guide track  4  that is turned toward fixed window  2 . It runs facing upper flitch  7 . Bend  16  runs from there toward lower flitch  6 . It is adhered to fixed window  2 . 
     Two guide grooves  19 ,  20  are provided in upper flitch  7 , in which the corresponding guide pegs (not shown in the drawing) of movable window  3  engage, and are guided thereby in a sliding manner. At one end of each guide groove  19 ,  20  there is a cleaning hole  21 ,  22 , so that guide grooves  19 ,  20  are self-cleaning and long-lasting function is guaranteed. 
     As shown in  FIG. 6 , two locating faces  23 ,  24  are provided on rib  9 . Locating face  23  is formed by the right end face of rise  11 . Locating face  24  is formed by the left end face of rise  11 ′, which is adjacent to rise  11  to its right. The corresponding locating faces of intercalation  8  are the right end face of lengthwise slit  12  and the left end face of lengthwise slit  12 ′, which is adjacent to lengthwise slit  12  to its right. As shown in  FIG. 6 , area  25  of intercalation  8  between lengthwise slits  12  and  12 ′ lies between locating faces  23  and  24  of lower flitch  6 . The space between locating faces  23  and  24  is exactly as long as the length of area  25 , so that area  25  lies snugly between locating faces  23  and  24  without any play. 
     The adjacent area  26  on the right side of intercalation  8 , between lengthwise slits  12 ′ and  12 ″, is somewhat shorter than the distance between right end face  27  of rise  11 ′ and left end face  28  of rise  11 ″. In this way, expansion gaps  29  and  30  are formed between the ends of area  26  and adjacent end faces  27  and  28 , by means of which the different heat expansions of the individual pieces, that is, lower flitch  6 , upper flitch  7 , and intercalation  8 , can be compensated for. 
     Rises  11 ,  11 ′,  11 ″ are situated opposite corresponding rises  31 ,  31 ′,  31 ″ of upper flitch  7 , which can be formed on ribs of upper flitch  7 . Joining points  15  are located in the areas where rises  11 ,  11 ′,  11 ″ and  31 ,  31 ′,  31 ″ overlap. Depressions  32  are provided between rises  31 ,  31 ′, and  31 ″ of upper flitch  7 . 
     Guide track  4  is connected to fixed window  2 , namely by adhesion. A safeguard is created by two catches  5  that are connected to body  1  by an adhesion  40  and that have an attachment surface  33  and a clip  34 . Clip  34  is comprised of a upward-pointing tongue  35 , from which a hook  36  is extended by bending, and a clamping piece  37  that points in the same direction as hook  36  and that is bent out of the middle portion of tongue  35 . 
     Clip  34  is clamped in between bend  16  of intercalation  8  and the rear end wall  37  of lower flitch  6 , as shown in  FIG. 4 . For this purpose, rear end wall  37  has an indentation  38  that is engaged by the tip of hook  36 . 
     Clip  34  is connected to attachment surface  33  of catch  5  via a crimp  39 . Attachment surface  33  lies flat against fixed window  2 . At its lower end it is adhered to fixed window  2 , namely by the same adhesion  40  by means of which fixed window  2  is adhered to body  1 . In addition, attachment surface  33  of clip  34  of catch  5  is also adhered to body  1  by means of adhesion  40 . 
     Lower flitch  6  and upper flitch  7  are connected, namely bonded, at their outer edges by another joining point  41 . Rear end wall  37  of lower flitch  6  has a groove  42  for each catch  5 , and the depth of the groove essentially matches the thickness and corresponding strength of tongue  35 . 
     In the described embodiment, internal stresses can arise due to temperature fluctuations. For this purpose, lengthwise slits  12 ,  14  of intercalation  8 , running lengthwise along guide track  4 , and corresponding rises  11 ,  13  of lower flitch  6  are useful. In the event that fixed window  2  breaks, catches  5  prevent pieces of side window  2  and movable window  3  from entering the interior of the vehicle. 
     The described embodiment allows for inexpensive manufacture using simple tools. The adhesive connections enable low-stress fastening. In this way, a high level of stability can be achieved. In addition, a great unity of design is made possible, since additional masking is unnecessary, so that a large design surface is available.
