Abstract

(57) [Summary] [Purpose] To eliminate the feeling of protrusion at the time of a side collision due to the bracket that also functions as a spacer interposed between the door inner panel and the door trim. [Structure] A bracket 5 having a substantially U-shaped cross section, which is integrally molded on the back surface of the door trim 1 and has a clip 4 attached to an end wall portion, and a door grip 10 fixed together with the door trim 1 by being sub-assembled to a door inner panel 3. Flexible portions 9 and 13 which are corrugated in a bellows shape are formed on each peripheral wall portion of the bracket 12 having a substantially U-shaped cross section.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vehicle door trim mounting structure.

[0002]

[Prior Art]

 Automobile door trims are detachably attached to door inner panels with clip members and screw members, but the door inner panel surface has uneven surfaces to enhance surface rigidity and to form mounting parts for various door functional parts. Since it is formed on the general surface of the door inner panel, a bracket having a substantially U-shaped cross section is interposed as shown in Japanese Utility Model Laid-Open No. 58-160820, and the door trim is attached to the general surface of the door inner panel by the bracket. A clip member or a screw member is used to fix the fixing member through the bracket with a required space.

[0003]

[Problems to be solved by the device]

 Since the bracket is interposed between the door inner panel and the door trim at the required height, when the door enters the passenger compartment during a side collision of the vehicle or the occupant inertially moves to the door side and interferes with the door trim. However, the bracket may give a passenger a feeling of protrusion.

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

[0005]

[Means for Solving the Problems]

 In a structure in which a door trim is detachably fixed to a door inner panel via a bracket that also serves as a spacer having a substantially U-shaped cross section, a flexible portion that is corrugated in a bellows shape is formed on a peripheral wall portion of the bracket. ..

[0006]

[Action]

 When the occupant interferes with the bracket-interposed portion of the door trim during a side collision of the vehicle, it is possible to avoid giving the occupant a feeling of protrusion by the bracket because the flexible portion of the bracket peripheral wall portion is compressed and deformed by the collision load at this time. It is also possible to absorb the collision energy by the compression deformation of the bracket and increase the amount of collision energy absorbed by the door trim.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

1 to 4, reference numeral 1 denotes a door trim made of a resin material that covers the surface of the door inner panel 3 of the door body 2, and the door trim 1 has a hook portion (not shown) formed at its upper edge portion. The door inner panel 3 is attached to a waist flange (not shown), and the front, rear and bottom edges of the door trim 1 are detachably fixed to the door inner panel 3 by a plurality of clips 4. ..

A bracket 5 made of metal and having a required height, which also serves as a spacer, is integrally molded at the site where the clip 4 is provided in the door trim 1. The bracket 5 is formed in a substantially U-shaped cross section, and the slit 6 and the mounting hole 7 are continuously provided in the end wall portion, and the head of the clip 4 is inserted into the slit 6 and the mounting hole 7 in the end wall portion. The flange 8 is formed so as to be engaged and fixed, and the end wall of the peripheral wall portion is bent, and the flange 8 is molded on the door trim 1 as described above and fixed to the back surface of the door trim 1. A flexible portion 9 corrugated in a bellows shape is formed on the peripheral wall portion.

The clip 4 is attached to the end wall portion of the bracket 5 in advance, and after the hook portion of the upper edge of the door trim 1 is attached to the waist flange of the door inner panel 3, the front and rear edges of the door trim 1 are attached. By pressing the portion and the bottom edge against the surface of the door inner panel 3, the clip 4 is press-fitted and attached to the clip hole 3a formed in the door inner panel 3, and the bracket 5 is provided with the clip 4. The bracket plate thickness 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 engaging work.

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

According to the above-described structure of the embodiment, when the occupant interferes with the bracket 5 interposition portion of the door trim 1 at the time of a side collision of the vehicle, the collision load at that time causes the flexible portion of the peripheral wall portion of the bracket 5 to collide. It is possible to prevent the occupant 9 from being compressed and deformed to give the occupant a sense of protrusion due to the presence of the bracket 5. When the occupant interferes with the door trim 1 and the collision load is applied to the door trim 1 as a whole, the flexible portions 9 and 13 of the respective peripheral walls are compressed and deformed. It is possible to increase the amount of collision energy absorbed by the door trim 1 by absorbing the collision energy by the compressive deformation of 9 and 13. Further, since the brackets 5 and 12 can be flexibly deformed in the radial direction by the flexible portions 9 and 13, the mounting error of the clip 4 or the door grip 10 to the door inner panel 3 is absorbed, and the door trim 1 is removed. It can be properly attached to the inner panel 3.

[0013]

[Effect of the device]

 As described above, according to the present invention, since the bracket also serving as the spacer interposed between the door inner panel and the door trim has the flexible portion corrugated in a bellows shape on its peripheral wall portion, When the occupant interferes with the door trim during a side collision of the vehicle and the collision load acts, the flexible portion does not deform and does not give a feeling of protrusion to the occupant, and the collision energy can absorb the collision energy. It is possible to increase the impact energy absorption amount of the door trim. Further, since the bracket can be flexibly deformed in the radial direction at 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 flexural deformation in the radial direction, and the accuracy of mounting the door trim can be improved. It has a great effect in practical use.
