【産業上の利用分野】本考案は、側突時の衝撃を緩和す

イニング用の衝撃緩衝部材に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock-absorbing member for a door lining which is mounted inside a door lining in order to reduce a shock in a side collision.

ングＲの内側に取り付けられている。2. Description of the Related Art Conventionally, as a shock absorbing member of this kind, as shown in FIG. 4, a rectangular side wall portion 1 having a rising dimension of about 70 to 200 mm is formed vertically.
A hollow box having a substantially E-shaped cross section having an opening 3 is formed by integrally molding the upright wall 2 at the center of the inside of the side wall 1. The shock absorbing member is mounted inside the door lining R with the opening 3 facing the door inner panel as shown in FIG.

緩衝部材では側壁部１並びに立壁部２が垂直に立上げ形
成されているから、座屈方向が内向きまたは外向きと一
定方向にならないことにより圧縮荷重が異なる。This shock buffering member functions to buffer a shock by buckling and crushing the side wall portion 1 and the central standing wall portion 2 under a compressive load at the time of a side collision. However, in the shock absorbing member, since the side wall portion 1 and the upright wall portion 2 are formed so as to rise vertically, the compressive load is different because the buckling direction is not fixed inward or outward.

みが厚くなるよう形成されているため、側突時の圧縮荷
重によっては潰れにくい構造のものであり、この要因を

異なるのを避けられない。Further, in the shock absorbing member, since the side wall portion 1 and the upright wall portion 2 are formed so as to increase in thickness from the tip to the base portion due to the necessity of removal from the mold, they are crushed by a compressive load at the time of a side collision. It has a structure that is difficult to achieve, and it is inevitable that the compressive loads differ while having the same shape, including this factor.

いことから型抜きし難い構造のものになる。In the shock absorbing member, as shown in FIG. 6, the side wall 1 and the upright wall 2 are located parallel to the direction of release, so that a die having the core die C formed in a block structure must be used. For this reason, the structure of the mold is difficult to be processed, and the structure of the side wall 1 and the standing wall 2 is difficult to remove because of the high rise.

The buckling direction can be standardized in a fixed direction, and the shock buffering value due to the buckling of the side wall portion can be easily determined, and the shock buffering value can be reliably set by adjusting the thickness of the side wall portion. In addition, since the hollow box-shaped rising portion is provided at the center of the inner side of the outer frame portion, the buckling of both portions can exert an appropriate shock absorbing action.
