BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a door trim for an automobile.

[0002]

2. Description of the Related Art A door trim for an automobile is detachably fixed to a door inner panel by a clip member or a screw member.
Since it is formed on an uneven surface to form attachment portions for various door functional parts, for example, as shown in Japanese Utility Model Application Laid-Open No. 58-160820, a bracket having a substantially U-shaped cross section is interposed. The door trim is fixed to the general surface of the door inner panel by the bracket at a required interval, and is fastened by a clip member or a screw member via the bracket.

[0003]

[Problem to be Solved by the Invention] Since the bracket is interposed between the door inner panel and the door trim at a required height, the door enters the vehicle interior at the time of a side collision of the vehicle, or the occupant has inertia toward the door side. When it moves and interferes with the door trim, the bracket may give a feeling of protrusion to the occupant.

Accordingly, the present invention does not impair the spacer function of the bracket, does not cause a feeling of protrusion due to the bracket at the time of a side collision of the vehicle, and effectively utilizes the bracket as a collision energy absorbing member. It is intended to provide an automobile door trim that can be used.

[0005]

A bracket is fixedly mounted on the back surface of the door trim , and a bracket is provided in a mounting hole of the bracket.
In the lip was engaged and fastened to the door trim to the door inner panel in the clip structure, said bracket having a bottom
While being formed in a cylindrical shape, a flexible portion which is formed into a bellows shape on the peripheral wall portion of the bracket is formed over the entire circumference , and
In addition, an opening over the end wall is formed in the peripheral wall of the bracket.
Formed, the mounting hole in the end wall portion of the bracket,
A slit extending from the hole to the opening is formed .

[0006]

When the occupant interferes with the bracket interposed portion of the door trim at the side collision of the vehicle, the collision load at this time compresses and deforms the flexible portion of the bracket peripheral wall to give the occupant a feeling of protrusion due to the bracket. The collision energy can be absorbed by the compression deformation of the bracket, and the amount of collision energy absorbed by the door trim can be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

1 to 4, reference numeral 1 denotes a door trim made of a resin material for covering a door inner panel 3 surface of a door body 2, and the door trim 1 is provided with a hook (not shown) formed on an upper edge thereof. The door trim 1 is engaged with an unillustrated waist flange, and the front, rear and bottom edges of the door trim 1 are secured to the door inner panel 3 by a plurality of clips 4.
It is detachably fastened to.

A metal bracket 5 having a required height, which also serves as a spacer, is provided on the portion of the door trim 1 where the clip 4 is provided.
Are integrally molded. This bracket 5
It is formed in a bottomed cylindrical shape , and straddles the end wall 5b on the peripheral wall 5a.
An opening 20 is formed. Furthermore, by interconnects the slit 6 and the mounting holes 7 in the end wall portion 5b, engaging by inserting the head of the clip 4 in the end wall portion 5b slit 6, the mounting hole 7, so as to secure The flange 8 which is bent and formed on the edge of the peripheral wall portion 5a has the door trim 1 as described above.
And is fixed to the rear surface of the door trim 1. The peripheral wall 5a has a flexible portion 9 formed in a bellows shape over the entire circumference .

The clip 4 is pre-engaged and disposed on the end wall of the bracket 5, and after engaging the hook at the upper edge of the door trim 1 with the waist flange of the door inner panel 3, the front and rear edges of the door trim 1 are provided. The clip 4 is pressed into and engaged with a clip hole 3a formed in the door inner panel 3 by pressing the bottom edge against the surface of the door inner panel 3, and the bracket 5 is engaged with the clip 4. The thickness of the bracket plate is appropriately set so that the flexible portion 9 of the peripheral wall portion is not compressed and deformed by the pressing force during the operation.

Reference numeral 10 denotes an armrest portion 11 of the door trim 1.
The door grip 10 is fixed to the door inner panel 3 together with the door trim 1 via a bracket 12 also serving as a spacer. The bracket 12 is formed to have a substantially U-shaped cross section as described above, and a flexible portion 13 formed in a bellows shape is formed on a peripheral wall portion thereof, and a bent flange 14 is formed on an edge of the peripheral wall portion. It is fastened to the door inner panel 3 by screws 15 and is sub-assembled to the door inner panel 3. The door grip 10 and the door trim 1 are fastened and fixed to the end wall of the bracket 12 by screws 16.

According to the structure of the above embodiment, when the occupant interferes with the bracket 5 interposed portion of the door trim 1 at the time of a side collision of the vehicle or the like, the collision load at this time causes the flexible portion 9 of the peripheral wall of the bracket 5 to fall. Can be prevented from being compressed and deformed to give the occupant a feeling of protrusion due to the presence of the bracket 5.
Further, when the occupant interferes with the door trim 1 and a collision load acts on the door trim 1 as a whole, the flexible portions 9 and 13 of the respective peripheral wall portions are compressed and deformed. The collision energy is absorbed by the compression deformation of the door trims 9 and 13, so that the collision energy absorption amount of the door trim 1 can be increased. Further, the bracket 5,
12 can be bent and deformed in the radial direction by the flexible portions 9 and 13, so that the clip 4
Alternatively, the door trim 1 can be properly mounted on the door inner panel 3 by absorbing the mounting error of the door grip 10.

[0013]

As described above, according to the present invention, the bracket which also serves as a spacer interposed between the door inner panel and the door trim has a flexible portion which is formed into a bellows shape on the peripheral wall portion. Therefore, when an occupant interferes with the door trim at the time of a side collision of the vehicle and a collision load is applied, the flexible portion is compressed and deformed without giving the occupant a feeling of protrusion,
Moreover, since the collision energy can be absorbed by the compression deformation, the collision energy absorption amount of the door trim can be increased. Further, since the bracket can be bent and deformed in the radial direction by the flexible portion, the displacement of the mounting position of the door trim with respect to the door inner panel can be absorbed by the bending deformation in the radial direction, and the mounting accuracy of the door trim can be improved. It has a great effect in practical use.
