ルギ吸収部をトリム本体と一体成形又は別体成形の如何
にかかわらず型抜きが困難で成形性が悪くなってしまう
ことは否めない。Since the energy absorbing portion has a honeycomb structure, it is difficult to release the energy absorbing portion from a resin material regardless of whether the energy absorbing portion is formed integrally with the trim body or separately. It is undeniable that the moldability deteriorates.

とで衝突エネルギ吸収性能に差が生じてしまう。Further, since the energy absorbing portion has a honeycomb structure, the initial reaction force at the time of buckling deformation becomes large, and it is difficult to obtain an ideal low reaction force deformation mode. When the input acts, the energy absorbing portion receives the load in the falling direction, so that a difference occurs in the collision energy absorbing performance between the case where the collision input acts in the axial direction and the case where the collision input acts in the oblique direction. .

しまう不具合を生じる。Further, when the above-mentioned honeycomb structure is formed of a resin material, it is necessary to increase the thickness of the partition walls of the honeycomb to a certain extent in order to reduce the initial reaction force at the time of buckling deformation. It is necessary to increase the protruding height from the rear surface of the trim body, which not only reduces the cabin space, but also causes a problem that the weight of the trim increases and goes against weight reduction of the vehicle body.
