Abstract
When a vehicle accelerates to a predetermined value, a pretensioner mounted to an occupant seat applies a pulling force to a seat belt under a force produced by detonating an explosive material. When the seat is moved in the longitudinal direction of a vehicle in order to adjust the position and the seat comes to a halt at a frontal end position, an acceleration more than or equal to the predetermined value is developed in an acceleration sensor. However, the acceleration sensor is provided with a lock means mounted to the seat. Even if the seat suddenly stops at the frontal end position, the acceleration sensor is restrained from moving and the pretensioner is not actuated. The lock means is actuated even when a walk-in mechanism for directly moving the seat to the frontal end is operated.
