Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile interior part such as an automobile door trim and a rear side trim located on the side of an occupant, and more particularly to a side impact such as a side collision applied to the vehicle. The present invention relates to an automobile interior part having a shock absorbing function for alleviating the impact on the vehicle.

[0002]

2. Description of the Related Art Conventionally, a door trim is installed on the interior side of a door panel, and a rear side trim is installed on the side of a rear seat occupant of a two-door hardtop vehicle to improve interior aesthetics and to prevent side impact such as side impacts. On the other hand, the occupants are protected.

For example, referring to FIG. 8 and FIG. 9 and exemplifying a vehicle door trim, a door trim 2 is mounted on the interior side of a door panel 1 of the vehicle.
A surface material 4 having cushioning properties and decorative properties is attached to the surface of a core material 3 having shape retention and mounting rigidity to the door panel 1, and a door trim 2 is attached to the door panel 1 via a mounting clip (not shown). A shock absorbing pad 5 made of foam is attached to a predetermined position on the back surface of the core material 3.

With respect to the passenger in the room, which has a relatively weak impact from the side, the cushioning property of the skin material 4 of the door trim 2 has a function of absorbing the impact load, such as a side impact. When a comparatively strong impact is applied, the impact load is absorbed by the deforming action of the door panel 1 which is a hollow structure, and the deforming action of the impact absorbing pad 5 attached to the back surface of the door trim 2, thereby protecting the occupant's safety. Is achieved.

[0005]

As described above, in the prior art, when a comparatively strong impact is applied from the side such as a side collision, the deformation of the door panel 1 and the deformation of the shock absorbing pad 5 cause the occupant to receive the impact. Although it is configured to absorb shock, the shock absorbing pad 5 is expensive, and a polyolefin resin such as polypropylene resin having poor adhesiveness is used as the material of the core material 3 of the door trim 2 in consideration of cost and moldability. In the case of using a polyurethane resin foam as the shock absorbing pad 5, a separate primer treatment must be applied when using polyurethane foam or the like, and the material of the shock absorbing pad 5 is limited. In addition to this, there was a defect that the mounting work was troublesome.

Furthermore, in the countermeasures by the shock absorbing pad 5,
There is also a possibility that the shock absorbing pad 5 may deteriorate due to a change with time, and the elastic force of the shock absorbing pad 5 varies due to the clearance between the door panel 1 and the door trim 2, and a constant shock absorbing performance cannot be ensured. .

The present invention has been made in view of such circumstances, and instead of eliminating an expensive shock absorbing pad, a shock absorbing means capable of effectively absorbing a side impact load can be simply and inexpensively installed. The purpose is to provide the interior parts for automobiles.

[0008]

In order to achieve the above object, the present invention is directed to a strip-shaped bracket made of an elastic material having both ends fixed to the back surface of a trim body mounted on the interior side of a vehicle body panel. It is characterized in that the central portion of is projected toward the vehicle body panel side, and the energy at the time of a side collision is absorbed by this protruding portion.

Further, since the locking hook is set on one side of the belt-shaped bracket and the vehicle body panel and the receiving portion is set on the other side, the belt-shaped bracket constitutes a mounting means of the trim body to the vehicle body panel. It is characterized by

Further, the strip-shaped bracket is characterized in that it constitutes a mounting bracket for mounting another component such as a pull handle mounted on the trim body.

[0011]

As apparent from the above structure, since both ends of the strip-shaped bracket are fixed to the back surface of the trim main body while the central portion of the strip-shaped bracket made of an elastic body is projected to the vehicle body panel side, side impacts, etc. When a shock is applied from the side,
The projecting portion of the belt-shaped bracket is pressed against the vehicle body panel, and the projecting portion is bent, so that a side impact can be effectively absorbed.

Furthermore, if a hook and a receiving portion for locking are set between the strip-shaped bracket and the vehicle body panel, the strip-shaped bracket constitutes the mounting means of the trim body, so that a mounting clip or the like which is the conventional mounting means. The number of settings can be reduced.

Similarly, if the strip-shaped bracket is used as a bracket for mounting another component such as a pull handle, the conventional bracket for mounting a pull handle can be eliminated.
