Description

[Detailed Description of the Invention] This invention relates to a mounting structure for a pillar trim in an automobile.

As a conventional mounting structure of this type, there is one shown in FIG. 1, for example.

(Utility Model Application Publication No. 53-74817, Utility Model Application No. 54-194
(See Publication No. 21) In the figure, 1 is a pillar.

This pillar 1 is constructed by joining flanges provided on both edges of an outer plate 1a and an inner plate 1b to form a first flange portion 2 and a second flange portion 3.
By raging and raging.

The first flange part 2 has a recess 4 formed by cutting and raising the inner plate 1b at a plurality of places in the longitudinal direction of the pillar 1, and the second flange part 3 has a recess 4 formed by cutting and raising the inner plate 1b at a plurality of places in the longitudinal direction of the pillar 1. The recessed step portion 5 is formed by cutting out a plurality of places in the longitudinal direction.

6 is a pillar trim made of synthetic resin that covers the pillar 1 from the inner plate 1b side.

A protrusion 7 that is inserted into the recess 4 is formed on the first flange 2 side of the pillar trim 6, and a protrusion 8 that fits into the recess 5 is formed on the second flange 3 side. The provided trim flange 9 is integrally formed.

Reference numeral 10 denotes a welt that is attached to the second flange portion 3 and the trim flange 9, in which the concave step portion 5 and the convex step portion 8 are fitted and overlapped, and clamps and fixes them.

In addition, 11 is a window glass fixed to the first flange part 2 via adhesive 12, 13 is a window molding, and 14
is the door and IC is its receiving part.

With this configuration, when attaching the pillar trim 6 to the pillar 1, the protrusion 7 of the pillar trim is inserted into the recess 4 of the first flange 2, and then the protrusion 8 of the trim flange 9 of the pillar trim 6 is inserted. is fitted into the concave stepped portion 5 of the second flange portion 3, the two 3 and 9 are overlapped, and then the welt 10 is attached to them.

However, in such a conventional pillar trim mounting structure, the pillar trim 6 is placed in the recess 4 of the first flange portion 2.
When inserting the protrusion 7, there is a problem that the insertion operation is a blind operation, and since the recess 4 is small and narrow, it is difficult and time-consuming to insert the protrusion 7.

This idea was created by focusing on these conventional problems, and when attaching a pillar trim to a pillar, it is necessary to attach the latching holes and engagement holes that are formed parallel to each other in the longitudinal direction of the inner plate of the pillar. , the latching claws and engaging protrusions of the pillar trim provided at corresponding positions are respectively latched and press-fitted, and then a welt is attached to the overlapping flange portion of the pillar and the trim flange of the pillar trim. The purpose is to solve the above problems by doing so.

Hereinafter, this invention will be explained in FIG. 2 (the same parts as in FIG. 1 are denoted by the same reference numerals, and the explanation thereof will be omitted.

).

First, the configuration will be explained.

In the figure, P is a pillar, T is a pillar trim, and W is a weld.

The pillar P is composed of an outer plate 15 and an inner plate 16, and a first flange portion 17 and a second flange portion 18 are formed by joining flanges on both sides.

The inner plate 16 is cut and raised at a plurality of places near the first flange portion 17 in the longitudinal direction, that is, the first piece 19
A and a second piece 19b are arranged opposite each other and cut and raised inward and outward to form a latching hole 19, and the cut and raised first piece 19a functions as a guide piece for guiding a latching claw 21 of a pillar trim T, which will be described later. However, the second piece 19b is upright so as to function as a receiving part for the pillar trim T and a latching part for the projection 7.

On the other hand, on the side of the second flange portion 18 of the inner plate 16, an engagement protrusion 2 of a pillar trim T, which will be described later, is provided in parallel with the above-mentioned latching hole 19.
An engagement hole 20 for press-fitting 2 is bored.

This engagement hole 20 is elongated in the lateral direction of the pillar P, and serves to facilitate alignment with the engagement protrusion 22 of the pillar trim T.

The pillar trim T has the second latching hole 19 on its inner surface.
On the side of the piece 19b, a locking pawl 21 and a thick-tipped engagement protrusion 22 that can be press-fitted into the engagement hole 20 are provided parallel to the longitudinal direction of the pillar trim T, respectively.

Further, this pillar trim T is formed with a trim flange 23 that overlaps with the second flange portion 18 of the pillar P when it is attached to the pillar P, as shown in FIG.
Overlapping second flange portion 18 and trim flange 23
The welt W is attached to the top so that it can be clamped and fixed.

Next, the procedure for installing the pillar trim T will be explained with reference to FIGS. 2 and 3.

First, the pillar trim T is applied to the pillar P from the direction of the arrow A as shown in FIG.
Slide it over 9a.

Then, just when the engaging protrusion 22 hits the engaging hole 20 of the pillar P, it is press-fitted into the engaging hole 20 and assembled to the position shown in solid line in FIG. 2.

Then, the trim flange 23 of the pillar trim T and the second flange 18 of the pillar P overlap as shown in FIG. 2, so a weld W is attached to both 18 and 23 to clamp and fix them.

In the above embodiment, the locking pawl 21 may be bent in the direction of the first flange portion 17 of the pillar P due to the relationship with the shape of the locking hole 19.

As mentioned above, this idea has a configuration in which the pillar trim is attached to the inner plate of the pillar and is assembled by sliding it along the trim.
and can be easily assembled.

Therefore, it is no longer necessary to perform the difficult and time-consuming work of blindly inserting the protrusion of the pillar trim into the narrow recess of the pillar flange as in the past, and the efficiency of the pillar trim assembly work is improved.
