Patent number: 6173990Abstract: During a collision, an air bag causes deformation of a roof head lining as the air bag expands. A roof head lining deformation limiting structure restricts inward deformation of the roof head lining. Thus, the roof head lining is prevented from interfering with an interior equipment, e.g., a sun visor, thereby reducing breakage of the sun visor provided adjacent the roof head lining. The deformation limiting structure can take the form of an assist grip or a card holder. Also, the assist grip or the card holder can be mounted onto a member, e.g., a bracket, that plastically deforms upon being struck by the occupant's head during a collision, thereby absorbing a portion of the impact that would otherwise be transferred to the occupant.Type: GrantFiled: September 24, 1998Date of Patent: January 16, 2001Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroki Nakajima, Toshimitu Watanabe
