摘要

The withdrawable unit (VS1) has a reversible actuator, which moves a safety element such that a working section is released, where the reversible actuator is operated such that the working section returns to a state before the operation. A controller actuates a pyrotechnical actuator on reaction to a collision detection signal and the reversible actuator on reaction to a collision forecasting signal. The working section has a locking section, which is secured by the safety element. The safety element has a pre-stressing unit to pre-stress the safety element.
