Abstract: Provided is an interior side wall structure for a vehicle in which a cylindrical shape of a shock-absorbing member can be crushed and deformed in an axial direction in an orderly manner upon vehicle side collision. When a collision load (F) is input to a shock-absorbing member (10) in the axial direction, a flange portion (13) at a peripheral edge of an open part is uniformly pressed against a door trim (4). At a connecting portion (15) of a peripheral wall (11), stress is distributed by an arc shaped face, whereby the development of crack is avoided, thus enabling even distribution of the load. At the connecting portion (15), buckling rigidity is adjusted by a slit for compression buckling adjustment (16) so as to substantially equalize the buckling rigidity at each portion of the peripheral wall (11), whereby the cylindrical shape of the shock-absorbing member (10) is crushed and deformed in the axial direction in an orderly manner.

Abstract translation: 本发明提供一种车辆的内侧壁结构，其中在车辆侧面碰撞时，减震构件的圆筒形状可以有序地沿轴向方向被破碎和变形。 当冲击载荷（F）在轴向方向上被输入到减震构件（10）时，在开口部分的周缘处的凸缘部分（13）被均匀地压在门饰件（4）上。 在周壁（11）的连接部（15），通过弧形面分布应力，避免了裂缝的发展，能够均匀地分布负荷。 在连接部分15处，通过用于压缩弯曲调节（16）的狭缝来调节屈曲刚度，以便使周壁（11）的每个部分的屈曲刚度基本相等，从而减震的圆柱形状 构件（10）以有序的方式在轴向上被破碎和变形。
