Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automotive trim structure .

[0002]

2. Description of the Related Art As shown in, for example, Japanese Utility Model Laid-Open Publication No. 1-144112, a trim for a vehicle is provided with a cushion such as a soft pad on a rear surface of a trim covering a vehicle body panel surface. Even if the occupant moves inertia toward the vehicle body side and collides with the vehicle body in the event of a side collision of the vehicle , or if the vehicle body enters the vehicle interior and collides with the occupant, the cushioning material is used. There has been known an apparatus which is designed to reduce the impact applied to a vehicle to protect occupants.

[0003]

While buffer material [devised is to solve the above is integrally molded to the back of the trim, complex uneven for practical for assembly of the machine構部goods vehicle body panel surface, and the panel surface improved rigidity Due to the planar shape, it is difficult to integrally mold the cushioning material so that it can be filled into the concave portion of the vehicle body panel surface, and a sufficient cushioning effect cannot be obtained.

[0004] Therefore, the present invention also the space between the trim and the vehicle body panel 4 is a heterogeneous, there is provided an automotive trim structure can obtain an optimal collision energy absorbing characteristics.

[0005]

In formed by attaching the trim to the vehicle body panel structure SUMMARY OF THE INVENTION, the back surface of the front Quito rim, abutting ribs to the body panel surface extending in the longitudinal direction, a plurality integrally in the vertical direction with molded, the ribs, the thickness in the width direction space small site between the trim and the vehicle body <br/> panel is made larger than the thickness of a large site space.

[0006]

[Action] occupant seated in the seat when a side collision of the vehicle when the collision to the trim by inertial movement to the vehicle body, the ribs by the collision input absorbs collision energy by elastic deformation.

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

In FIGS. 1 and 2, reference numeral 1 denotes a door body comprising a door inner panel 2 and a door outer panel 3, 4 denotes a door trim for covering the door inner panel 2 surface of the door body 1, and the door trim 4 comprises a trim waist. Hook (4a) formed at the edge of the section (TW) is attached to the door inner panel (2).
, And the front, rear and lower edges are fixed to the door inner panel 2 by clips 5 and mounted.

A predetermined portion on the back of the door trim 4, specifically, when the occupant sits on a seat (not shown), a portion corresponding to the body side from the shoulder to the chest of the occupant is provided on the back of the door trim 4. A plurality of ribs 6 projecting integrally in the front-rear direction and projecting from the surface of the door inner panel 2 are arranged vertically.

The ribs 6 project from the door inner panel 2 so as to have different amounts of protrusion in accordance with the unevenness of the door inner panel 2 so as to properly abut the door inner panel 2. The rib 6 is formed so as to have a different thickness depending on the space in the width direction between the inner panel 2 and the inner panel 2. That is, the rib thickness is increased at the portion where the space in the width direction is small, and the rib thickness is reduced at the portion where the space in the width direction is large. Therefore, the space in the width direction
Small part, that is, the amount of compressible deflection of rib 6 (small
(Troke) is smaller in the portion where the rib 6 is
A large reaction force is generated, as shown in the collision energy absorption characteristics of Fig. 3.
The reaction force at the beginning of the deformation stroke rises sharply
Will be .

According to the structure of the embodiment described above, when an occupant seated on the seat moves by inertia toward the door at the time of a side collision of the automobile and collides with the door trim 4, the ribs 6 are caused to collide with the door trim 4 by the collision input. It is compressed and deformed or bent by the inner panel 2 and the collision energy can be absorbed by these elastic deformations.

Here, as described above, by increasing the thickness of the rib 6 at a portion where the space in the width direction between the door trim 4 and the door inner panel 2 is small, the collapse stroke of the rib 6 can be effectively used. As a result, the amount of energy absorption can be increased by sharpening the rise of the buffer characteristic, and the buffer characteristic can be arbitrarily obtained by setting the thickness of the rib 6.

Further, since the ribs 6 project in the front-rear direction of the door trim 4, the ribs 6 are easy to form, unlike those which project in accordance with the change of the vertical shape of the door inner panel 2 in the vertical direction. There is also an advantage that the protrusion amount can be easily adjusted by cutting or the like. As mentioned above, this invention
The case of applying to the trim has been described.
It is not limited to this, it is attached to the body panel
The general trim can be applied .

[0014]

As described above, according to the present invention, a plurality of ribs are provided on the rear surface of the trim, which are integrally protruded in the front-rear direction and abut on the panel surface of the vehicle body. because of Te, by changing in accordance with the thickness dimension of the rib trimmed, in the width direction space between a vehicle body panel, the collapse characteristics, therefore,
To be able to buffer characteristic arbitrarily changed, it is possible to easily obtain the optimum properties by a change in the rib thickness, effective use of narrowly constrained gap between Application Benefits <br/> arm and the vehicle body panel As a result, an excellent buffer effect can be obtained.
