The invention relates to an emergency exit for safety motor vehicles which has an exploding element for fitting on a locking mechanism of a vehicle door. The exploding element is arranged at a point of separation (T) provided between a door hinge (2) and the vehicle door (1), and is arranged in a threaded bolt (3) joining the hinge (2) to the vehicle frame (6) or to the door (1). The voltage required for ignition is provided to the exploding element via a supply line (4). In order to guarantee the reliable ignition of the exploding element, a defined ignition voltage (UZ) is provided to said exploding element via a control device (S). The ignition voltage is generated by the control device (S) either from the vehicle electrical system (UB) or, during failure of the vehicle electrical system, via a battery (B2) which is independent of said vehicle electrical system. In addition, an energy storage element (12.1, 12.2) is arranged either on both sides relative to or arranged at the point of separation (T). When the explosive element is triggered and the threaded bolt breaks (8), the energy storage element releases its energy and the parts to be separated are pushed apart. |
