  • Impact energy absorbing structure for vehicle cabin
    Patent number: 6126231
    Abstract: This invention relates to an impact energy absorbing structure for a cabin of an automotive vehicle. The impact energy absorbing structure is provided with a trim member (10) covering an inboard side of a structural member, which constitutes the cabin of the automotive vehicle. An impact absorbing member is interposed between the inboard side of the structural member and the trim member (10), so that impact energy directed from a surface of the trim member (10) toward the structural member can be absorbed. When an occupant of the cabin is about to hit the structural member, impact energy is damped so that the occupant can be protected. The structural member includes a pillar (1) or the like, which constitutes the cabin of the automotive vehicle. The trim member (10) is arranged to cover an inboard side of the pillar (1) or the like. Resin-made ribs (11) or the like can be mentioned as the impact absorbing member.
