The device has a shock-absorbing device employed when a pedestrian hits the bonnet (11) which is raised, so that an assembly consisting of the bonnet, a raising mechanism and a piston (17), moves under the effect of the impact. A hollow body (16) has small...

The safety device (1) has a lifting mechanism (3) for lifting a bonnet (29), an actuator (16) fitted with a pyrotechnic gas generator, and a latching hook (4) for latching the lifting mechanism. The latching hook is mounted pivotally and attached to a moto...

The actuator has a pyrotechnic gas generator (7), a combustion chamber (3) and a piston (9) placed in a sliding chamber under the effect of gas. The combustion chamber has an obturation device (4) that is implemented after the activation of the actuator fo...

The device has a pyrotechnic actuator (22) to move a piston (9). A cable (21) has an end connected to a fixed part (27) of a vehicle. The actuator is connected to a piece to be dampened and cooperates with the cable to slow down and then stop the piece. Th...

The system has a pyrotechnic gas generator (5), and a sliding piston (7) displaced in a damping chamber (2). The generator (5) liberates gas into the chamber (2) for damping the piston (7). The gas generator (5) delivers a variable quantity of gas. The dam...

The seatbelt pretensioner (1) has a pyrotechnic actuator (2) with a piston (9) and a cord (3) whose one end (16) is connected to a fastening buckle of this seatbelt. The pyrotechnic actuator has a hollow body (5) including a pyrotechnic gas generator (6) a...

The device is situated under this hood and has a lifting mechanism (2) of this hood. An actuator actuates with the aid of a gas generator (31), and a locking device of this lifting mechanism, this mechanism having a connecting link (20). The actuator is ad...
