2. Description of the Related Art Normally, interior parts such as rear side trims are installed in the interior of a vehicle, such as rear door trims in the side of a rear passenger in a vehicle door trim installed in a door panel and a two-door hardtop vehicle. In addition to the improvement, the occupants are protected against impact from the side.

More specifically, FIGS. 8 and 9 show an example of a door trim provided in a door panel.
A door trim 2 for an automobile is usually installed on the interior surface of the vehicle. The door trim 2 for an automobile has a shape retention property and rigidity for mounting to the door panel 1, and has a core material 3 formed into a desired curved surface shape, and the core material 3 A surface material 4 having a cushioning property and a decorative property is covered and adhered to the front surface side of 3.

[0004] A door trim 2 is formed by forming an armrest portion 5 and a waist portion 6 so as to protrude toward the passenger compartment so as to correspond to the waist and shoulders of the occupant.

When a shock is applied to the vehicle from the side, a relatively small shock is absorbed by the cushioning property of the skin material 4 and a relatively large shock such as a side collision is absorbed. A shock absorbing pad 7 or the like is stuck on the back surface of the core material 3 and a relatively large impact load such as a side impact is absorbed by the elastic action of the shock absorbing pad 7 installed between the door panel 1 and the door trim 2. It is configured to be.

As described above, the conventional vehicle door trim 2 can absorb a relatively small impact due to the cushioning performance of the skin material 4, but has the armrest portion 5 of the door trim 2 where the waist of the occupant is likely to hit.
Because the rigidity is set high in consideration of the armrest function and the like, it depends on the cushioning property of the skin material 4 and the curved shape of the core material 3 when a large impact from the side such as a side collision is applied. Although a part of the impact is absorbed by the bending characteristics, for a large impact, the impact absorbing performance of the impact absorbing pad 7 alone is not enough to alleviate the impact applied to the occupant. It has been urgently needed to effectively reduce the impact on the occupant with respect to the relatively large impact from the vehicle.

The present invention has been made in view of such circumstances, and when a relatively large impact load is applied from the side such as a side impact, the armrest is broken to effectively absorb the impact load. It aims to provide automotive interior parts.

In order to achieve the above-mentioned object, the present invention is constructed by attaching a skin material to a surface of a core material formed in a required shape and mounted on the indoor side of a vehicle body panel. In addition, in an automotive interior part having an armrest upper member installed on the upper surface of an armrest lower part bulging toward the indoor side, the armrest upper members are disposed at appropriate intervals in the vertical and horizontal directions and intersect with each other. The armrest core material surface made of a rod-shaped body is covered with an armrest pad and an armrest skin.

Further, another aspect of the present invention is configured such that a skin material is attached to the surface of a core material formed into a required shape and attached to the interior side of a vehicle body panel, and swells to the interior side. In an automobile interior part in which an armrest upper member is installed on an upper surface of an armrest lower portion, the armrest upper member is configured by enclosing an armrest core material surface with an armrest pad and an armrest skin, and the armrest core material includes: A plurality of breaking openings along the center of the base plate, at least one side of the breaking slit is opened,
In the event of a side collision, the armrest core material is broken into two right and left parts to absorb an impact load.

[0010]

[Action] As is apparent from the above configuration, the armrest core material serving as the base of the armrest upper member is
It is arranged at appropriate intervals in the vertical and horizontal directions and has a plurality of intersecting rods or a plate-shaped base core with multiple openings for rupture. When an impact is applied, the armrest core material is broken, so that the impact can be largely absorbed.
