Abstract
A buckle pretensioner for a vehicle seat belt system of the type that is mounted on a vehicle seat includes a blocking device for preventing the movement of a movable member of an inertial starting mechanism that controls the operation of the pretensioner from releasing the pretensioner driving device. The blocking device includes a solenoid and an electric power circuit for energizing the solenoid having a seat slide switch that is responsive to movement of the seat release lever for controlling the energy state of the solenoid so that the blocking device prevents movement of the movable member in response to operation of the seat release lever to release the seat for adjustment and a delay circuit for maintaining the energy state of the solenoid established by operation of the seat slide switch for a predetermined period of time after the seat slide switch has been operated. The power circuit may also have a switch that is responsive to insertion of a buckle tongue into the buckle for controlling the energy state of the solenoid such that the blocking device prevents movement of the movable member of the inertial starting mechanism when the buckle tongue is not inserted into the buckle.
