Title: Occupant protection device for vehicle
Inventor: KORE HARUHISA
IPC: B60R22/46
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To avoid a false alarm for a rear collision and the unnecessary restraint of occupants by seatbelts due to the presence of an fixed object such as a guardrail on the side of a road. SOLUTION: A seatbelt 11 is strongly pulled by a motor 16 to strongly restrain an occupant J against a seat 3 a predetermined time after the time when a vehicle 2 behind is expected to collide with the rear of one's own vehicle 1. If a determination is made that there is the possibility of the rear collision prior to actuation of the motor 16, an alarm means 22 such as a buzzer is actuated. For an alarm corresponding to the rear collision and for occupant restraint control, a distance sensor 21 for detecting the distance to the vehicle behind is mounted at the rear of the vehicle 1.  During cornering or turning at an intersection, the sensor 21 detects the wall surface 41 of a guardrail or the like on the outside of the turn of the vehicle 1, and the error of recognizing that the vehicle behind is approaching is likely to occur as the result of the closer distance to the wall surface 41 as the vehicle travels. When the speed of the vehicle 1 is equal to or greater than a predetermined speed and the steering angle is equal to or greater than a predetermined steering angle, the alarm and the restraint of the occupants by the seatbelts are inhibited.
