Trim mounting structure

A claw-shaped protrusion is installed at the edge of one trim so that a forked portion is formed between the edge of the trim and the claw-shaped protrusion, a plurality of protrusions are formed at the edge of the other trim, and these trims are installed to the vehicle body in a condition where relative positioning between the trims is performed by inserting the edge of the other trim into the forked portion of one trim and abutting the side of the claw-shaped protrusion against the protrusions.

FIELD OF THE INVENTION AND RELATED ART STATEMENT 
The present invention relates to a structure for mounting trim used as an 
interior part for a motor vehicle, etc, and, more particularly to a 
structure for mounting trim, which is suitable for the application to a 
split-type pillar trim for a T-bar roof type motor vehicle. 
For a T-bar roof type motor vehicle in which a detachable roof can be 
installed detachably to an opening, a female (engagement hardware) for 
installing the detachable roof is normally disposed at each end of a front 
roof and a rear roof. By using the females, the detachable roof can be 
installed to the opening for the T-bar roof. 
Specifically, for the T-bar roof type motor vehicle, a female for 
installing a detachable roof, which has an engagement hole, is disposed at 
the upper part of a pillar portion, and a shaft corresponding to the 
engagement hole of the female is mounted to the detachable roof covering 
the opening for the T-bar roof. Therefore, the detachable roof can be 
attached to the opening for the T-bar roof and can be supported by 
inserting the shaft of the detachable roof into the engagement hole of the 
female so that the shaft engages with the engagement hole. 
The aforementioned female is normally covered by pillar trim, which is an 
interior part of the pillar portion, in order not to impair the appearance 
of the cabin interior. Therefore, the detachable roof is actually attached 
by engaging the shaft of the detachable roof with the engagement hole of 
the female through a shaft insertion hole formed in pillar trims (front 
pillar trim and rear pillar trim). 
To readjust the installation position of the detachable roof, it is 
necessary to adjust the installation position of the female. In performing 
this adjustment work, the pillar trim must be removed from the pillar 
portion of the vehicle body. In order to facilitate this removal work, it 
is convenient to construct the pillar trim 30 in such a manner that, as 
shown in FIG. 12, only the upper portion corresponding to the installation 
position of the female, which is a part of the pillar trim 30, is 
constituted as pillar upper trim 30b, a separate member separated from the 
pillar trim body 30a, and a shaft insertion hole 31 is formed in the 
pillar upper trim 30b so that the readjustment work of the female can be 
performed by independently removing the pillar upper trim 30b. 
In this case, an installation construction of the pillar upper trim 30b can 
be thought such that position control (positioning) vertical and 
longitudinal with respect to the vehicle body, as indicated by arrows X 
and Z in FIG. 13, is performed by simply joining the pillar upper trim 30b 
to the pillar trim body 30a in a plane as shown in FIG. 13, and the pillar 
upper trim 30b is screwed in the pillar portion of the vehicle body with a 
tapping screw 33 by using a screw insertion hole 32 of the pillar upper 
trim 30b. 
However, when the installation construction shown in FIGS. 12 and 13 is 
used, in assembling the pillar upper trim 30b, the worker must hold the 
pillar upper trim 30b at a predetermined position by hand until the pillar 
upper trim 30b is fastened with the tapping screw 33. This holding work is 
troublesome. 
Because the edge of the pillar upper trim 30b and the edge of the pillar 
trim body 30a are joined in a plane as shown in FIG. 13, when the pillar 
upper trim 30b is assembled to the pillar trim body 30a before being 
screwed with the tapping screw 33, the position control in the vehicle 
width direction (the direction indicated by the arrow Y in FIG. 12, or the 
direction perpendicular to the paper in FIG. 13) is not performed, and 
additionally the position control vertical with respect to the vehicle 
body is insufficient. Therefore, it is difficult to hold the pillar upper 
trim 30b at the correct assembling position. 
OBJECT AND SUMMARY OF THE INVENTION 
The present invention was made to solve the above problems. Accordingly, an 
object of the present invention is to provide a trim mounting structure 
constructed so that when one trim (for example, a pillar upper trim) is 
assembled to the other trim (for example, a pillar trim body), the need 
for holding work for the time until one trim is assembled and screwed to 
the other trim is eliminated, and these trims can be positioned easily and 
accurately in any direction: vehicle width direction, vertical direction 
of the vehicle body, and longitudinal direction of the vehicle body. 
To achieve the above object, according to the present invention, the trim 
mounting structure is constituted so that a claw-shaped protrusion is 
installed at the edge of one trim so that a forked portion is formed 
between the edge of the trim and the claw-shaped protrusion, a plurality 
of protrusions are formed at the edge of the other trim, and these trims 
are installed to the vehicle body in a condition where relative 
positioning between the trims is performed by inserting the edge of the 
other trim into the forked portion of one trim and abutting the side of 
the claw-shaped protrusion against the protrusions. 
Also, according to the present invention, the one trim and the other trim 
are members composing a pillar trim of a T-bar roof type motor vehicle, 
and the one trim or the other trim is a member for covering a female for 
mounting a detachable roof at the upper part of the pillar trim. 
According to the above constitution in accordance with the present 
invention, the positioning (position control) of the trims to be assembled 
is performed in the vehicle width direction, the vertical direction of the 
vehicle body, and the longitudinal direction of the vehicle body by means 
of the engaging construction between the forked portion formed on one trim 
and a plurality of protrusions formed on the other trim and the abutting 
construction between the claw-shaped protrusion of the forked portion and 
the protrusion. Therefore, the trims to be assembled can be fixed 
temporarily when being installed, so that the need for the work of holding 
the trim for the time from assembling to screwing can be eliminated, by 
which the trim assembling work is made easy.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
An embodiment of the present invention will be described below with 
reference to FIGS. 1 to 11. 
FIG. 1 shows a T-bar roof type motor vehicle. The T-bar roof type motor 
vehicle includes what we call a T-bar roof (sometimes merely called a T 
roof) of a T shape, which consists of a front roof 2 or a rear roof 3 
extending along the vehicle width direction and a central roof 4 connected 
between substantially middle portions of the roofs 2 and 3. The roof 
portion defined by this T-bar roof forms a pair of right and left U-shaped 
openings 6a and 6b. Detachable roofs 7 covering these openings 6a and 6b 
are mounted detachably. 
The aforementioned detachable roofs 7 are mounted to the openings 6a and 
6b, respectively, by engaging a pair of shafts 12a and 12b installed to 
the detachable roof 7 with engagement holes 11a and 11b in females 10a and 
10b for mounting the detachable roof, which are located at the side 
portion of the front roof 2 and the rear roof 3 and at the upper portion 
of a front pillar 8 and a rear pillar 9, respectively (see FIGS. 2 and 3). 
The females 10a and 10b for mounting the detachable roof are, as shown in 
FIGS. 2 and 3, bolted to the vehicle body portions above the front pillar 
8 and the rear pillar 9, and covered by front pillar trim 13 installed 
inside the front pillar 8 and rear pillar trim 14 installed inside the 
rear pillar 9, respectively, to improve the appearance. 
In this embodiment, the portions which are the upper parts of the 
aforementioned front pillar trim 13 and rear pillar trim 14 and correspond 
to the places where the aforementioned females 10a and 10b are mounted are 
constructed by separated members which are separated from the pillar trim 
body. Specifically, the front pillar trim 13 is composed of a pillar trim 
body 13a and a separate pillar upper trim 13b which is assembled to the 
upper part of the pillar trim body 13a. Likewise, the rear pillar trim 14 
is composed of a pillar trim body 14a and a separate pillar upper trim 14b 
which is assembled to the upper part of the pillar trim body 14a. 
After being installed to the vehicle body, the aforementioned females 10a 
and 10b are concealed by the pillar upper trims 13b and 14b, respectively, 
to improve the appearance of the vehicle cabin. When it is necessary to 
readjust the installation position of the detachable roofs 7 in the 
openings 6a and 6b of the T-bar roof, only the pillar upper trims 13b and 
14b can be singly removed from the pillar trims 13a and 14a and the 
vehicle body. 
Next, the construction of the connecting part of the pillar trim body 13a 
and the pillar upper trim 13b of the front pillar trim 13 will be 
described. 
As shown in FIG. 4, the connection edge of the pillar trim body 13a is 
formed in a serrated shape, and four protrusions 16 are integrally formed 
at predetermined positions in the connecting direction (direction of the 
face of the pillar trim body 13a). The connection edge 15 is provided with 
a step portion 15a corresponding to the plate thickness of the pillar 
upper trim 13b as shown in FIGS. 6 and 8. On the other hand, at the inside 
of the connection edge 17 of the pillar upper trim 13b, two claw-shaped 
protrusions 18 are integrally formed at predetermined positions, which 
protrude from the connection edge 17 in the direction intersecting with 
respect to the connecting direction. Thus, a forked portion 20 having a 
concave 19 of a substantially V shape in cross section is formed by the 
connection edge 17 and the claw-shaped protrusion 18 opposed to the 
connection edge 17 as shown in FIG. 8. The distance between two paired 
protrusions 16 is almost equal to the width of the claw-shaped protrusion 
18. 
The construction of the connecting part of the pillar trim body 14a and the 
pillar upper trim 14b of the rear pillar trim 14 is similar to the 
construction for the front pillar trim 13. Specifically, as shown in FIG. 
5, two protrusions 22 are integrally formed at the connection edge 21 of 
the pillar trim body 14a, and two claw-shaped protrusions 24 are 
integrally formed at the inside of the connection edge 23 of the pillar 
upper trim 14b. The connection edge 21 is provided with a step portion 21a 
corresponding to the plate thickness of the pillar upper trim 14b as shown 
in FIGS. 7 and 10. Thus, a forked portion 26 having a concave 25 of a 
substantially V shape in cross section is formed by the connection edge 23 
and the claw-shaped protrusion 24 opposed to the connection edge 23 as 
shown in FIG. 10. The inside distance between two protrusions 22 and 22 in 
the width direction is almost equal to the outside distance between the 
claw-shaped protrusions 24 and 24 in the width direction. 
As shown in FIGS. 4 and 5, the pillar upper trims 13b and 14b are provided 
with shaft insertion holes 27a and 27b for inserting the shafts 12a and 
12b of the detachable roof 7 and screw insertion holes 28a and 28b for 
inserting tapping screws 33 for mounting the pillar upper trims, 
respectively. 
Next, the installation work for installing the front pillar trim 13 and the 
rear pillar trim 14 to the vehicle body will be described. First, the 
pillar trim bodies 13a and 14b are installed to the front pillar 8 and the 
rear pillar 9 in advance, and then the pillar upper trims 13b and 14b are 
assembled to the installed pillar trim bodies 13a and 14a, respectively. 
In assembling the pillar upper trim 13b, the part between the paired 
protrusions 16 and 16, which is a part of the connection edge 15 of the 
pillar trim body 13a, is inserted into the concave 19 disposed in the 
pillar upper trim 13b as shown in FIGS. 6 and 8. The tip end 15b of the 
connection edge 15 is abutted against the innermost surface 19a of the 
concave 19 of the pillar upper trim 13b as shown in FIG. 8. Therefore, as 
shown in FIG. 9, the sides of the paired protrusions 16 of the pillar trim 
body 13a are in contact with both sides 18a of the claw-shaped protrusion 
18 of the pillar upper trim 13b, so that the claw-shaped protrusion 18 is 
held between the paired protrusions 16. 
As a result, the position control of the pillar upper trim 13b with respect 
to the pillar trim body 13a in the direction indicated by the arrow X (see 
FIGS. 6 and 8), that is, the vertical direction of the vehicle body, is 
performed by inserting the connection edge 15 of the pillar trim body 13a 
between the connection edge 17 and the claw-shaped protrusion 18 and 
abutting the tip end 15b against the innermost surface 19a of the concave 
19. 
Further, the position control of the pillar upper trim 13b with respect to 
the pillar trim body 13a in the direction indicated by the arrow Y (see 
FIGS. 6 and 9), that is, the vehicle width direction, is performed by 
holding the connection edge 15 between the connection edge 17 and the 
claw-shaped protrusion 18. 
Still further, the position control of the pillar upper trim 13b with 
respect to the pillar trim body 13a in the direction indicated by the 
arrow Z (see FIGS. 6 and 8), that is, the longitudinal direction of the 
vehicle body, is performed by holding the claw-shaped protrusion 18 of the 
pillar upper trim 13b between the paired protrusions 16 and 16 of the 
pillar trim body 13a. 
In this embodiment, therefore, the vertical, lateral, and longitudinal 
position control of the pillar upper trim 13b with respect to the pillar 
trim body 13a, which has been installed to the front pillar 8 in advance, 
can be performed, so that the pillar upper trim 13b can be assembled to 
the trim body 13a with the relative movements in all directions being 
inhibited. Therefore, by merely assembling the pillar upper trim 13b to 
the pillar trim body 13a, the pillar upper trim 13b is held in a 
temporarily fixed condition, so that it is unnecessary for the worker to 
hold the pillar upper trim 13b by hand for the time from the assembly of 
the pillar upper trim 13b to the installation thereof to the vehicle body. 
After the pillar upper trim 13b is assembled to the pillar trim body 13a in 
a temporarily fixed condition as described above, the pillar upper trim 
13b is screwed to the vehicle body with a tapping screw 33 by using the 
screw insertion hole 28a of the pillar upper trim 13b. Thus, one front 
pillar trim 13 is formed with the pillar trim body 13a and the pillar 
upper trim 13b being combined with each other, and fixedly arranged on the 
inside of the front pillar 8. The joint portion of the pillar trim body 
13a and the pillar upper trim 13b is flush due to the presence of the step 
portion 15a, which provides a smooth, flat appearance. 
The rear pillar trim 14 is installed in substantially the same manner as 
the aforementioned case of the front pillar trim 13, as shown in FIGS. 7, 
10, and 11. For the rear pillar trim 14, however, the one side 24a of one 
claw-shaped protrusion 24 of the pillar upper trim 14b is abutted against 
the side 22a of one protrusion 22 of the pillar trim body 14a, and the 
other claw-shaped protrusion 24 is abutted against the other protrusion 22 
at the place on the opposite side. In this case too, position control is 
performed not only in the direction indicated by the arrow Y (vehicle 
width direction) but also in the direction indicated by the arrow X 
(vertical direction of the vehicle body) and the arrow Z (longitudinal 
direction of the vehicle body) because the paired right and left 
claw-shaped protrusions 24 and 24 are held between the paired right and 
left protrusions 22 and 22. 
With such a trim mounting structure, the pillar upper trims 13b and 14b are 
assembled to and temporarily fixed to the pillar trim body 13a and 14a 
while their positions are controlled exclusively in any direction, so that 
the screwing work of the pillar upper trims 13b and 14b to the vehicle 
body can be performed easily and efficiently. Even if the pillar upper 
trims 13b and 14b are removed by loosening the screws in order to readjust 
the installation position of the detachable roof 7, the pillar upper trims 
13b and 14b are held in the temporarily fixed condition, so that there is 
no possibility that the pillar upper trim 13b and/or 14b come off 
unexpectedly. 
Although one embodiment of the present invention has been described above, 
the present invention is not limited to the above embodiment, and various 
changes and modifications may be made in light of the above teachings. For 
example, the shape and construction of the protrusions 16 and 22, the 
claw-shaped protrusions 18 and 24, the forked portions 20 and 26, etc. may 
be changed variously if necessary. 
In contrast with the above embodiment, the pillar trim bodies 13a and 14a 
may be provided with forked portions 20 and 26 by installing the 
claw-shaped protrusions 18 and 24, whereas the pillar upper trims 13b and 
14b may be provided with the protrusions 16 and 22. 
Although the present invention has been applied to the front and rear 
pillar trims 13 and 14 in the above embodiment, it is obvious that the 
present invention can be applied to various trims other than the pillar 
trims. 
As described above, according to the present invention, the edge of one 
trim is inserted into the forked portions formed on the other trim, and 
these trims are combined with the protrusions of one trim being abutted 
against the sides of the claw-shaped protrusions composing the forked 
portions in order to install the trims to the vehicle body. Therefore, the 
trims can be assembled easily in such a manner that the position control 
of one trim with respect to the other trim is performed in all directions: 
vehicle width direction, vertical direction of the vehicle body, and 
longitudinal direction of the vehicle body, and one trim can be surely 
held in a temporarily fixed condition without relative movement with 
respect to the other trim by merely performing assembly. This decreases 
the manpower for assembly, and eliminates the need for the worker to hold 
the trim at the assembling position for the time from the completion of 
trim assembly to the start of trim installation, by which the trim 
installation work can be performed easily and efficiently. 
For T-bar roof type motor vehicles, the installation position of the 
detachable roof can be conveniently readjusted by adjusting the 
installation position of the female for mounting the detachable roof by 
merely removing only one trim covering the female for mounting the 
detachable roof. In addition, in removing one trim covering the female, 
the temporarily fixed condition is held when one trim is removed from the 
vehicle body, so that a work trouble such that one trim comes off 
unexpectedly can be avoided.
