Abstract

An occupant protection device includes: a collision prediction part (22); a seatback actuator (28) that adjusts a reclining angle; a seatbelt retracting part (32); a reclining angle sensor (30); and a controller (26) that sets the reclining angle to a target angle and that controls the seatbelt retracting part (32) so that the seatbelt is retracted when the collision prediction part determines that a collision will occur. Accordingly, the controller executes a control so that the driving force of seatbelt retracting part (32) when the reclining angle is decreased is smaller than at least one of the driving force of seatbelt retracting part (32) when the reclining angle is not changed or when the driving force of seatbelt retracting part (32) when the reclining angle is increased.

Description

technical field [0001] The present invention relates to an occupant protection device, and in particular, to an occupant protection device that predicts a collision to protect an occupant. Background technique [0002] Various technologies have been proposed as occupant protection devices for protecting occupants in the event of a collision. For example, related technologies include: an occupant protection device that protects an occupant by properly adjusting the posture of the occupant by tilting the seat back forward if the seat back is tilted in a collision prediction state; and An occupant restraint device that protects an occupant by retracting a seat belt in a collision prediction state. [0003] This type of occupant protection device has been described, for example, in Japanese Patent Application Laid-Open No. 11-334437 (JP-A-11-334437). In the technique disclosed in JP-A-11-334437, the occupant protection device determines that a collision is about to occur, and ...
