Description

[Detailed Description of the Invention] The present invention, vehicle interior trim mounting structure, especially interior) IJ
The present invention relates to an interior trim mounting structure in which a trim is attached and fixed to a vehicle body panel by the fitting action of a clip and a panel.

As shown in Figure 1, the clip 3 installed on the back of the interior trim is inserted into the hole made in the vehicle body panel.
A conventional method of mounting and fixing an interior trim by press-fitting it is generally used. There is something. These are fixing protrusions 5a, 5 aligned vertically on the rear pillar inner panel 5 attached to the inside of the outer panel of the vehicle body on the rear pillar 4 of the vehicle body 1.

However, in the conventional interior trim mounting structure, such clip mounting brackets 6a and 5b are fixed to the back surface of the pillar trim 2, which is the interior trim, or are integrally molded when the pillar trim 2 is injection molded.
, all of 5c are box-shaped with relatively high rigidity, so if you hit the pillar trim 2 by hand when installing the pillar trim 2 to the rear pillar inner panel 5, the distortion of the pillar trim 2 will increase and the surface will turn white. There was a problem with that.

The present invention has been made by focusing on such conventional problems, and its purpose is to absorb shock when driving clips into a platen F for attaching a plurality of clips provided on the back side of an interior trim such as a pillar trim. By making the structure relatively thin and having a shock absorbing part, the reaction force applied to the trim body when attaching the interior trim to the vehicle body panel is minimized, and the whitening phenomenon that appears on the surface of the interior trim is minimized. At the same time, the interior trim was attached to the vehicle body panel, and after it was installed, the interior trim was fixed and supported securely.
Embodiments of the present invention, which solve the above-mentioned conventional problems, will be described in detail with reference to the accompanying drawings.

FIGS. 3 and 4 are diagrams showing a first embodiment of the present invention. This embodiment shows an example in which a pillar trim is applied in the same way as described in the above conventional example. In the mounting structure of the pillar trim 2 shown here, brackets 16a, 16b, 160 molded from a relatively thin resin material are provided on the back surface of the pillar trim 2 and aligned in the vertical direction. These brackets 16a
, 16b.

16C, both have a shock absorber 11 with a substantially bellows structure between the top and the leg, and a relatively large half-shape at the lower end of the leg.
They are made of the same structure with a curved flange with a diameter R, and the heads are provided with clips 3a, 3b, respectively.
3c is attached and supported, while the legs are fixed to the back surface of the trim body 2a by ultrasonic welding. Shock absorber 1

When a blow is applied to the part c, the shock absorber 11 contracts and deforms due to this blow, and the trim body 2a is pressed against the rear pillar inner panel 5 and moves from the position shown in FIG. 4 1) to the position shown in FIG. 4 0). Displace to the position. During this work, the impact force applied to the main body of the bird 5 by the worker is approximately 1 kg, but the impact force is approximately 1 kg.

Toga hole 7a=To,? Eight kilograms is enough to combine cK&. During the above operation, the 11 shock absorbers deform to absorb 11 to 12 kilograms of shock, thereby preventing the bird main body 2a from deteriorating in rigidity and turning white. And clip 3at3bt3cFi,
After fitting into the holes 7a, 7b, and 7C, the trim body 2a is pushed back to the position shown in FIG.
support. In this case, due to the restoration of the shock absorber 11, the fourth Fl! A gap H as shown in J(4) is created, but this gap H is limited to about 1 mm at most, so after installing the pillar trim 2, the pillar body 2
There will be no waving or vibration in the paper. Also,
The shock absorbers 11 provided on the brackets 16a, 16b, and isc can be displaced not only in the direction perpendicular to the U-um body 2a (due to their elastic structure) but also in the 14-plane direction, thereby reducing installation errors of the pillar trim 2. It has the advantage of being easily absorbed.

FIG. 5 shows the platen in the first embodiment) 16
It is a figure which shows the 2nd Example of this invention which changed the structure of the bracket with a shock absorber corresponding to a t16bttc. In the interior trim mounting structure according to this embodiment, a shock absorber 12 made of thin resin is formed in a corrugated manner from the upper end portion of the leg extending substantially perpendicularly to the trim body 2a toward the center. A seven flange 17 is used in which the lower end portion of the leg portion is formed as thin as possible, and the lower end portion is formed into a relatively large radius hole to provide a leg seven lunge connection portion 17a. Clip 3
While the legs 7 are fitted and supported, the legs 7 are fixed to the back surface of the trim body 2a by ultrasonic welding as in the first embodiment.

And, before attaching the pillar trim 2 to the rear villa inner panel 5, the bracket 17 is the 58th! J(
As shown in A), the elastic action of the shock absorber 12 and the leg 7 flange connection part 17a maintains the free and inflated state, while the pillar trim 2 is not easily applied by the worker during the pillar trim 2 installation work. In order to absorb the impact, the clips 3a, 3kl, 3 contract as shown in Fig. 5.
After the holes 7a, 7b, and 7GK1 are aligned, the pillar trim 2 is restored to the original fk state shown in the fifth drawing and supports the pillar trim 2.

FIG. 6 is a diagram showing a third embodiment of the present invention in which the structure of the bracket with a shock absorber is changed. In this embodiment, the leg portion 18a1 of the bracket 18 and the connecting portion between the leg portion 18a and the leg 7 flange 18b are formed from a material as thin as possible, while the leg portion 18a is made to be inclined with respect to the trim body 2a. It is composed. and leg 7 lunge 18
The bracket 18 is attached by fixing b to the back surface of the trim body 2a by ultrasonic welding. By adopting such a configuration, the leg portion 18a itself can be bent quite freely due to the compressive stress of the external force 1, and serves as a shock absorber when the pillar trim 2 is attached. Before installing the pillar trim 2 to the rear pillar inner tunnel 5, the platen 1B, which was in the upright position 9 as shown in FIG.
During the installation work of the trim 2, in order to absorb the impact force applied to the platen N8, the platen N8 is contracted and deformed as shown in FIG. 6 (6), and the pillar trim 2 is installed to the rear pillar inner tunnel.

FIG. 7 is a diagram showing a fourth embodiment of the present invention in which the structure of the bracket with a shock absorber is further modified. In this example, as shown in FIG. 7 (4), five birds #
The leg portion 19a is formed to be inclined with respect to the trim body 2a when attached to the trim body 2a, and the leg 7 lunge i9b,! A bracket 19 is used, which has a plurality of circular holes 13 in the leg part 19a, and a notch 14 extending from the head part to the leg part 19a, which continues to the hole 15 for attaching the clip 3. There is. This bracket 19 is attached by fixing the leg 7 flange 19b to the back surface of the bird main body 2a by ultrasonic welding. In this way, since the plurality of holes 13 are formed in the leg portion 19a, the bracket 19
has a structure that is easily deformed at its leg portion 19a, and this leg portion 19a serves as a shock absorber when the pillar trim 2 is attached.

Before installing the pillar trim 2, the mounting bracket 19 maintains the upright position with the legs 19a extending straight, as shown in FIG. FIG. 7 (As shown in O, the leg 19
A is deformed at the opening of the hole 13 t, and the pillar trim 2 is attached to the rear pillar inner tunnel 5.

Figure 8 is a diagram showing a fifth embodiment of the present invention in which the structure of the bracket with a shock absorber is further modified. In this embodiment, when attached to the trim body 2a, the leg part 20a is formed to be inclined with respect to the trim body 2a, and the leg 7 lange 20 is connected to the lower end of a part of the leg part 20a.
b, and a trim abutting portion 20C that is formed on the same circumferential surface as the leg 7 flange 20b at the lower end of the remaining portion of the leg portion 20a and protrudes outward from the leg portion 20a. . This bracket 20 has legs 7
It is attached by fixing the lunge 20b to the back surface of the trim body 2a by ultrasonic welding, while when attaching this bracket 20, the trim abutment part 20C is not bonded to the back surface of the trim body 2a, but is simply in elastic contact. placed in In this way, the lower end portion of the leg portion 208 Fi is fixed to the bird main body 2a in a part thereof, while the other portion is freely movable with respect to the bird main body 2a. is the pillar)
Acts as a shock absorber when 17mm2 is installed. Therefore, before the pillar trim 2 is installed, the bracket 20 maintains its vertical position rising from the trim body 2a as shown in FIG. ) When installing the rim 2, as shown in Figure 8B), attach the bracket 20.
As the trim contact portion 20C is crushed by receiving the impact force □, the trim contact portion 20C is displaced along the back surface of the trim. Then, the clip 3 attached and fixed to the hole made in the head of the bracket member engages with the hole in the rear pillar inner panel 5, and the pillar trim 2
Install and fix.

As described above, various structures can be considered for the bracket with a shock absorber, but regardless of the structure, when attaching the pillar trim 2 to the rear pillar inner panel 5, the surface of the trim body 2a must be Even if it is strongly pressed, a strong impact force will not be transmitted to the bird main body 2a through the bracket.

As explained above, according to the present invention, the interior trim mounting structure is configured such that the interior trim is attached to the vehicle body by fitting a plurality of clips attached and fixed to the interior trim into a plurality of holes opened in the vehicle body panel. In the above, the clip is fixedly supported by a bracket equipped with a shock absorber to soften the impact received when installing the interior trim, so even if the interior trim is hit when installing the interior trim, it will not be affected by the impact. It is now possible to suppress as much as possible the occurrence of yielding in the interior trim itself, or the occurrence of a whitening phenomenon on the back side of the trim, while the interior trim itself can be supported reliably.
It is now possible to both maintain material strength and improve appearance quality.
