<p>PROBLEM TO BE SOLVED: To improve protective performance of the cervical vertebrae of an occupant by anticipating at least a rear-end collision of a vehicle. SOLUTION: This vehicular occupant restricting device is featured by being composed of a seat 1 provided in a vehicle 13 and composed of a seat cushion 17 and a seat back 19, a headrest 3 being arranged above the seat back 19 and supporting a head part H of the occupant seated on the seat 1, a head part restricting means 5 for generating restricting force for pressing down the head part H of the occupant seated on the seat 1 toward the headrest 3 side, a posture correcting means 7 for generating restricting force for straightening the backbone of the occupant seated on the seat 1, a rear-end collision detecting means 9 for at least previously detecting a rear-end collision of the vehicle 13 and a controller 11 for generating restricting force by controling driving of at least one of the head part restricting means 5 and the posture coreecting means 7 by at least previous detection of the rear-end collision.</p> |
