The door (7) of a car, bus, or train can be blocked by a deformation of the surrounding parts after a crash, preventing the passengers or the driver from escaping or a rescue worker from entering the vehicle (1). The unit is equipped with a sensor system (50) located at an appropriate spot and activating a spreading or cutting mechanism (20,25). The hinges (10,15) are broken or cut in order to open the door (7). The mechanism can also be designed for lifting the door from the hinges.
