Description
【０００１】[0001]
本考案は、側突時の衝撃を緩和するべくドアライニングの内側に取り付けられ るドアライニング用の衝撃緩衝部材に関するものである。 The present invention relates to a shock absorbing member for a door lining, which is attached to the inside of the door lining in order to reduce a shock at the time of a side collision.
【０００２】[0002]
従来、この種の衝撃緩衝用部材としては図５で示すように７０〜２００ｍｍ程 度の立上り寸法を有する四辺形の側壁部１を垂直に形成すると共に、立壁部２を 側壁部１の内側中央に一体成形することにより開放口３を有する横断面略Ｅ字状 の中空函形のものが用いられている。その衝撃緩衝部材は、図６で示すように開 放口３をドアインナーパネル側に向けてドアライニングＲの内側に取り付けられ ている。 Conventionally, as this kind of shock absorbing member, as shown in FIG. 5, a quadrilateral side wall portion 1 having a rising dimension of about 70 to 200 mm is formed vertically, and the standing wall portion 2 is formed at the inner center of the side wall portion 1. A hollow box-shaped member having an E-shaped cross section and having an opening 3 by integrally molding is used. The shock absorbing member is attached inside the door lining R with the opening 3 facing the door inner panel side as shown in FIG.
【０００３】 この衝撃緩衝部材は、側壁部１並びに中央の立壁部２が側突時の圧縮荷重を受 けて座屈し潰れることにより衝撃を緩衝するよう機能する。然し、その衝撃緩衝 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バラ付くことにより圧縮荷重が異なる。This shock absorbing member functions to buffer the shock by the side wall 1 and the central standing wall 2 receiving a compressive load at the time of a side collision and buckling and crushing. However, in the shock absorbing member, since the side wall portion 1 and the standing wall portion 2 are formed to rise vertically, the compressive load varies depending on whether the buckling direction is inward or outward.
【０００４】 また、この衝撃緩衝部材では側壁部１並びに立壁部２が脱型の必要上から先端 より基部に向って厚みが厚くなるよう形成されている。そのため、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、この要因を含めて同一形状を有す るものでありながら圧縮荷重が異なるのを避けられない。Further, in this shock absorbing member, the side wall portion 1 and the standing wall portion 2 are formed so that the thickness becomes thicker from the tip end toward the base portion because of the necessity of demolding. Therefore, it has a structure that does not easily collapse depending on the compressive load at the time of a side collision, and it is inevitable that the compressive load is different even though it has the same shape including this factor.
【０００５】 その衝撃緩衝部材では、図７で示すよう側壁部１並びに立壁部２が脱型方向と 平行に位置するから、コア型Ｃをブロック構造に形成した金型を用いなければな らない。このため、金型の加工が難しい構造のものになり、また、側壁部１並び に立壁部２の立上りが高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. 7, the side wall portion 1 and the upright wall portion 2 are positioned parallel to the demolding direction, and therefore, a mold in which the core mold C is formed in a block structure must be used. . For this reason, the mold has a structure that is difficult to process, and the side wall 1 and the standing wall 2 have a high rising edge, which makes it difficult to remove the mold.
【０００６】[0006]
本考案は、側突時の圧縮荷重による座屈方向を構造上一定にできて衝撃緩和値 を確実に定められ、また、構造的に脱型を容易に行えて簡略な構造の金型で形成 できるドアライニング用の衝撃緩衝部材を提供することを目的とする。 The present invention has a structure in which the buckling direction due to the compressive load at the time of a side collision can be made structurally constant, the impact relaxation value can be reliably determined, and the mold can be structurally easily removed from the mold with a simple structure. An object of the present invention is to provide a shock absorbing member for a door lining that can be used.

Therefore, the shock absorbing value due to buckling of the side wall can be easily determined, and the shock absorbing value can be reliably set by adjusting the thickness of the side wall. Further, since the side wall portion is inclined, mold release can be easily performed, and since a punch hole that reduces the rigidity of the side wall portion can be provided without using a slide mold, the shock absorbing effect can be further enhanced. It can be formed with a simple mold.
【００１１】 本考案の請求項２に係るドアライニング用の衝撃緩衝部材では、立上り部を外 枠部の内側中央に設けることから、その両者の座屈で適度な衝撃緩衝作用を発揮 することができる。また、立上り部を外枠部の内側中央に一体成形する構造から コア型，キャビティ型を共に通常の倣い加工で形成可能なものにできる。In the shock absorbing member for door lining according to the second aspect of the present invention, since the rising portion is provided in the inner center of the outer frame portion, buckling of both of them can exert an appropriate shock absorbing action. it can. Further, the core mold and the cavity mold can both be formed by a normal copying process from the structure in which the rising portion is integrally molded in the inner center of the outer frame portion.
【００１２】 本考案の請求項３に係るドアライニング用の衝撃緩衝部材では、開放口の拡開 方向斜めに傾斜する側壁部による中空函形の構造体を複数個一体成形することか ら、これらが個々同時に座屈することにより適確な衝撃緩衝作用を発揮すること ができる。In the shock absorbing member for the door lining according to claim 3 of the present invention, since a plurality of hollow box-shaped structures are integrally formed by the side wall portion which is inclined obliquely in the expanding direction of the opening, these are integrally formed. By buckling each of them at the same time, it is possible to exert a proper shock absorbing effect.
