REVERSIBLE UNLOCKING SYSTEM OF A SAFETY DEVICE IN MOTOR VEHICLES

摘要

The invention relates to a reversible unlocking system for actuating a safety device in motor vehicles having a housing, comprising a pre-tensioned actuator (2) activating, in case of activation, an operating element of an energy storage unit locked in a locked state, wherein the locking device can be reversed into the locked position after unlocking, wherein the actuator (2) comprises a permanent magnet (24), a catch plate (5) acting together therewith as an operating element, and a switchable electromagnet, wherein the permanent magnet (24) holds the unlocking system in the locked position when the electromagnet is not energized, and the electromagnet is designed such that the magnetic field of the permanent magnet (24) is weakened when the electromagnet is energized, so that the catch plate (5) can be displaced into a position where the safety device is unlocking, by means of the energy storage unit, wherein the energy storage unit is tensioned during the unlocking process.
