Title: Occupant crash protector
Inventor: MOTOSAWA YASUKI
IPC: B60R22/46
Filed: 2001-07-18
Abstract: PROBLEM TO BE SOLVED: To achieve a reduction of injury value of an occupant by realizing a car body deceleration waveform preferably reducing deceleration of the occu pant with a simple structure. SOLUTION: A movable part provided on the car body side is moved to the direction strengthening restraint of the seat belt with an inertial mass member by a first acceleration generation means at the time of detecting a collision to stably generate deceleration larger than average deceleration (car body deceleration) in the movable part. If the movable part is moved by a predetermined amount, deceleration in the reverse direction is generated in the movable part by inhibiting the movement by a second acceleration generation means. Thereby, a car body deceleration waveform preferable for a reduction of the occupant deceleration can be realized.  Thereby, not only an impact to the occupant can be outstandingly reduced even in the case of a smaller deformation amount of the car body than the conventional one, but also a movement amount of the occupant relative to the car body in a cabin can be made small. Therefore, a possibility of a secondary collision can be reduced.
