摘要： The invention relates to a pyrotechnical actuator for a vehicle safety system comprising a cylinder (10) and a hollow piston (20) being displaceable relative to each other from an idle state to an activated state, wherein an igniter unit (30) being tightly connected to the hollow piston (20) is arranged inside the hollow piston (20). The invention excels by the fact that in the idle state the hollow piston (20) is received in the cylinder (10) and in the activated state it protrudes at least partially from the cylinder (10) so that the actuator has a larger total length in the activated state than in the idle state. The invention further relates to an actuator and a vehicle safety system comprising such actuator as well as to an actuating method.
