[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings. A pillar trim 3 is mounted on the A-pillar of the vehicle from the interior of the vehicle to finish the interior and improve the appearance. Therefore, as shown in FIG.
As shown in the figure, the pillar trim 3 is fixed at four locations on the rear side of the A pillar (the pillar inner panel 6) on the side of the vehicle body (the number of installation locations is changed as necessary).

As shown in FIGS. 1 and 2, the pillar trim 3
Is long and curved in the width direction, and inside the curved surface,
A plurality of ribs 8 are formed in the width direction, and an insertion projection 11 fitted to the instrument panel 4 at the lower end (see FIG. 3)
Are formed. The substantially flat protrusions 5 and the substantially rhombic protrusions 12 are formed so as to be mounted on the pillar inner panel 6. Further, the substantially flat projection 5 of the pillar trim 3 is formed at a conventional position, and the corresponding hole on the pillar inner panel 6 side is already opened, and the substantially rhombic projection 1 is formed.
Numeral 2 is located rearward of the vehicle body with respect to the substantially flat projection 5 (see FIGS. 5 and 6). The hole on the side of the pillar inner panel 6 into which the substantially rhombus-shaped projection 12 of the pillar trim 3 is inserted can use an existing jig hole (a reference hole for panel welding).

Further, as shown in FIGS. 7 and 8, in the pillar trim 3, the lower part is curved inward,
The pillar trim 3 is manufactured by molding using a synthetic resin. When the slide die is not used, the back side of the pillar trim 3 is cut by the two-dot chain line in the figure, but the extension e can be formed by using the slide die. This allows
On the lower surface, a character line (CL) as a boundary line of the convex bent portion of the design can be set at the same position as the parting line (PL).

Next, the substantially rhombus-shaped projection 12 will be described. As shown in FIG. 4, the substantially rhombus-shaped protrusion 12 may be located at any position on the back side of the pillar trim 3, but is formed on the rib 8 here. For this reason, the base 1 of the substantially rhombus-shaped protrusion 12
3 and the ribs 8 intersect to increase rigidity. The base 13 is formed in a trapezoidal shape, and a side hole 13a is formed in a side surface of the base 13 so that a connection portion between the base 13 and the main body (substantially rhombus-shaped protrusion 12) is made thin to prevent sink on the outer surface of the pillar trim 3. .
On the upper surface of the substantially semicircular surface of the base 13, a substantially rhombus-shaped projection 12 of a flat plate is formed.
A hole 15 is formed. The substantially rhombus-shaped projection 12 has a tip that is formed gradually thinner, and has a shape that allows easy insertion. Further, cross ribs 16 are formed on both sides of the substantially rhombus-shaped protrusion 12 at right angles to the surface of the rhombus-shaped protrusion 12 on the rear side of the vehicle body from the protrusion center axis. The cross rib 16 has a tapered surface in the insertion direction, and has a shape that allows easy insertion.
When is fitted into the hole of the pillar inner panel 6, the cross rib 16 abuts on the hole to support and fix the vehicle in the vertical direction. In the fitted state of the substantially rhombus-shaped projections 12, the base 13 abuts on the pillar inner panel 6, and the pillar trim 3 is positioned outside the vehicle.

Therefore, as shown in FIGS. 3, 5 and 6, when the pillar trim 3 is mounted on the pillar inner panel 6, the substantially rhombus-shaped projections 12 and the pillar inner panel 6
The hole has good consistency. Further, when the substantially rhombus-shaped projection 12 is inserted, the ridge portion of the outer edge of the punched hole 15 is pressed against the edge of the hole of the pillar inner panel 6 and bends, so that it is easy to insert into the hole. The ridge projections 14 prevent easy return. The cross ribs 16 contact the four peripheral surfaces of the hole to prevent rattling during assembly of the member. When attaching the opening trim 10, the ridge projection 14 acts so as not to separate the pillar trim 3 from the pillar inner panel 6. In addition, the cross ribs 16 increase the rigidity of the substantially rhombus-shaped projections 12, as a matter of course. In addition, the hole of the pillar inner panel 6 uses an existing jig hole, so that a drilling step is not required and the panel rigidity is maintained.

The pillar trim 3 is connected to the pillar inner panel 6.
When installed in the vehicle, the front side of the rib 8 is separated from the pillar inner panel 6 to provide a space, and the wire harness 17 is provided.
Etc. can be passed through. The rib 8 has a structure in which the rear side of the vehicle abuts against the pillar inner panel 6 to prevent rattling. The substantially rhombus-shaped projection 12 is located on the rear side of the vehicle body with respect to the substantially plate-shaped projection 5. With this arrangement, the pillar trim 3 is securely mounted, and the play is reduced.

As described above, in the embodiment shown in FIGS.
Although the pillar trim 3 is mounted using the substantially rhombus-shaped projections 12 and the substantially flat-plate-shaped projections 5, only the substantially rhombus-shaped projections 12 can be used. In that case, the clip 7 becomes unnecessary and the cost is reduced. Further, by using the jig holes, the number of holes can be reduced, the rigidity can be improved, and the cost can be reduced. Further, since the work is facilitated, the appearance of the pillar trim 3 can be maintained without fear of damaging the surface during the work.

On the surface of the pillar trim 3 which can be seen, a character line (C.
L. ) According to the position of the parting line (P.
L. ) Using a mold to determine the position of L. And the appearance can be improved. In addition, the thick portion on the back side of the pillar trim 3 can be formed with a constant thickness using a slide mold, thereby preventing warpage and deformation.

[0020]

The present invention is as described above. According to the first aspect of the present invention, a substantially rhombus-shaped projection is integrally formed on a pillar trim mounted inside a pillar of a vehicle body, so that the number of parts can be reduced and the cost can be reduced. Since it is possible to reduce the size and to form the projection integrally, it is possible to reduce the play after mounting. In addition, since the workability is improved, there is no risk of damaging the surface of the pillar trim, and the appearance can be maintained. According to the second aspect of the present invention, since the ridge projection and the cutout hole are formed in the planar substantially rhombic projection, the ridge portion can be flexibly inserted into the hole into which the substantially rhombic projection is inserted. It is easy to pull out due to the ridge projection, and the pillar trim can be securely attached.

According to the third aspect of the present invention, the substantially rhombus-shaped projection has a planar shape, and cross ribs are formed on both sides on the rear side of the vehicle body from the center of the projection. Is prevented from being deformed. In addition, since the protrusion and the end of the cross rib make contact with the inner peripheral surface of the hole corresponding to the insertion, play with the hole is reduced, and mounting of the pillar trim is ensured. According to the fourth aspect of the present invention, the ribs are formed at a plurality of intervals over substantially the entire width in the substantially width direction of the pillar trim, so that the surface rigidity of the pillar trim and the rigidity of the mounting portion of the substantially rhombus-shaped projection are improved, The distortion of the pillar trim is eliminated, and the appearance is improved.

According to the fifth aspect of the present invention, since the pillar trim is mounted by using the substantially rhombus-shaped projection and the substantially rectangular plate-shaped projection, it is possible to cope with the conventional pillar trim and to improve the assembling property. Further, since the pillar trim is securely fixed, the displacement of the connection with other members is reduced, and the appearance is improved. In the invention described in claim 6, the character line and the parting line of the pillar trim are aligned and formed at the same position, so that the appearance at the visual position is improved. In the invention according to claim 7, in forming the pillar trim, the thickness of the back side of the pillar trim is formed constant by the slide die, so that the thickness of the back side of the pillar trim can be constant, and the surface rigidity of the pillar trim is improved, The appearance is improved because warpage and deformation are prevented.
