Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a pillar trim such as a center pillar trim and a rear pillar trim which are installed in a center pillar panel, a rear pillar panel, etc., and particularly, a pillar trim having a simple and inexpensive structure. The present invention relates to a mounting structure for a pillar trim that prevents deformation of the pillar.

<< Prior Art >> Usually, a pillar trim such as a center pillar trim and a rear pillar trim is provided in a center pillar panel, a rear pillar panel, etc. on a vehicle body side, which enhances the aesthetics of a room and the safety of passengers.

In FIG. 3, a conventional pillar trim attachment structure will be described as an example.

In the drawings, a pillar trim 1 is mounted on the inside of a vehicle so as to cover the pillar inner panel 2, and a clip 4 mounted on a clip mounting seat 3 formed on the back surface side of the pillar trim 1 at appropriate intervals. The pillar inner panel 2 is fixedly attached.

Further, since the pillar trim 1 is composed of an injection molded body of synthetic resin, the pillar trim 1 tends to be deformed in the arrow direction in FIG. 3, that is, both side edges are deformed outward due to changes in the environmental temperature. There is a problem that a gap occurs between both side edges of the and the welt 8 and the interior aesthetics are deteriorated.

Therefore, conventionally, locking pieces 5 each having a substantially L-shaped cross section are provided on the right and left sides of the back surface of the pillar trim 1, and the locking flanges 7 of the pillar inner panel 2 and the pillar outer panel 6 are locked by a welt 8 that holds them together. A measure has been taken in which the tip portion of the piece 5 and the joint flange portion 7 are clamped to restrict the deformation of the pillar trim 1.

<Problems to be solved by the invention> However, in this countermeasure, since the locking piece 5 having a substantially L-shaped cross section is integrally provided on the back surface side of the pillar trim 1, the locking piece 5 has an undercut shape, and the pillar trim. It has been pointed out that a slide mold is required for injection molding No. 1, resulting in an increase in mold cost and an increase in product cost.

Furthermore, the welt 8 must be inserted while the tip end portion of the locking piece 5 is superposed on the indoor side surface of the joint flange portion 7 between the pillar inner panel 2 and the pillar outer panel 6, and the work is required. At the same time, it has been pointed out that it is very troublesome and causes a decrease in work efficiency.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to mold with a simple mold structure in a mounting structure of a pillar trim that prevents deformation of the pillar trim, and significantly reduce the molding cost of the product. With pulling down,
An object of the present invention is to provide a pillar trim mounting structure that enables smooth mounting work on the vehicle body side.

<Means for Solving the Problems> In order to achieve the above object, the present invention is mounted on the interior side of the pillar panel, and along the side surface of the interior of the welt that holds the joint flanges on both sides of the pillar panel, In a pillar trim mounting structure which is mounted so as to abut against both side edges thereof, ribs are provided so as to project along the both side edges on the left and right sides of the back surface of the pillar trim, and on the side surface of the welt in the passenger compartment along the outside of the ribs. And a stopper portion that restricts the movement of the rib is formed.

<Operation> As is apparent from the above configuration, according to the present invention, the ribs are formed on the left and right sides of the back surface of the pillar trim so that the pillar trim does not have an undercut shape. Is possible.

Further, since the stopper portion is formed along the outer side of the rib, even if both sides of the pillar trim are deformed in the direction of expanding outward, the rib abuts the stopper portion and is not deformed.

<< Embodiment >> An embodiment of a pillar trim mounting structure according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of the present invention, and is a sectional perspective view showing a state where a pillar trim is attached to a pillar panel,
FIG. 2 shows a second embodiment of the present invention and is a sectional perspective view showing a state in which a pillar trim is attached to a pillar panel as in FIG.

First, a first embodiment of the present invention will be described with reference to FIG.

Referring to FIG. 1, a center pillar trim 10 according to the present invention is shown.
Is molded by injection molding a general-purpose synthetic resin such as polypropylene resin, polyethylene resin, ABS resin, etc. as a long body having a substantially C-shaped cross section.

The center pillar trim 10 is mounted so as to cover the pillar inner panel 11, and
A pillar inner panel is formed by press-fitting a resin clip 13 to be mounted on a clip mounting seat 12 provided on the back surface of 10 at appropriate intervals along the longitudinal direction into a mounting hole 11a of the pillar inner panel 11. The center pillar trim 10 is attached and fixed to 11.

The left and right side edges 14 of the center pillar trim 10 are in contact with each other along the indoor side surface 17a of the welt 17 that holds the joint flange portion 16 between the pillar inner panel 11 and the pillar outer panel 15.

By the way, the feature of the present invention resides in the mounting structure of the center pillar trim 10 which prevents the center pillar trim 10 from being deformed to the left and right sides with a simple and inexpensive structure. That is, the ribs 18 are formed on the left and right sides of the back surface of the pillar trim 10 in a comb shape along the both side edges 14 while keeping a constant distance from the both side edges 14.

Then, with respect to this rib 18, the side surface of the cabin of the welt 17
A ridge 19 is formed along the outer side of the rib 18 to restrict the movement of the rib 18a.

Therefore, since the present embodiment is configured in this way, even if a force that deforms the center pillar trim 10 in the direction of the arrow in FIG. 1 acts, the rib 18 abuts on the ridge 19 and moves outward from the center pillar trim 10. The deformation of can be prevented as much as possible.
Therefore, the appearance of the terminal portion of the pillar trim 10 can be kept beautiful, and a gap is not generated, which does not cause a low-level sound.

Further, in this embodiment, the pillar inner panel 11
And after attaching the welt 17 to the joint flange portion 16 of the pillar outer panel 15, the center pillar trim 10 may be attached to the pillar inner panel 11, so that the tip portion of the locking piece is superposed on the joint flange portion as in the conventional case. The troublesome work of maintaining the condition and sandwiching the two in a welt can be omitted, and the work efficiency is significantly improved.

Next, FIG. 2 shows a second embodiment according to the present invention.
The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, the welt 20 is provided along the outside of the rib 18 that is formed so as to project on the left and right sides of the back surface of the center pillar trim 10.
Since the step portion 21 is formed on the rib, even if the center pillar trim 10 acts to expand and deform outward, the rib 18 abuts on the step portion 21, and the deformation of the center pillar trim 10 can be reliably prevented. The workability of attaching the center pillar trim 10 is improved as compared with the conventional one, and the same operational effects as those of the first embodiment are provided.

Although the present invention is applied to the center pillar trim in the above-described embodiments, the present invention can be applied to the front pillar trim, the rear pillar trim, etc. without any problem.

<Effect> As is clear from the above description, the pillar trim mounting structure according to the present invention has the following special operational effects.

According to the present invention, stoppers such as ridges and steps are provided on the welt along the outside of the ribs protruding on the left and right sides of the back surface of the pillar trim, and the ribs abut the stoppers. This has the effect that deformation can be reliably prevented.

According to the present invention, since the plate-shaped ribs are projected on the left and right sides of the back surface of the pillar trim, the shape of the center pillar trim does not become an undercut shape at the time of injection molding, and molding can be performed with an inexpensive mold structure. This has the effect of significantly reducing costs.

According to the present invention, after mounting the welt on the joining flange portion of the pillar panel, the pillar trim may be attached and fixed to the pillar panel. This has the effect of eliminating troublesome work such as slipping in and significantly improving work efficiency.
