Abstract:
1. A device in a motor vehicle for protecting passengers during a collision comprising: an energy source; a door of the motor vehicle; a vehicle seat located on an inboard side of the door; at least one sensor installed in the vehicle for triggering, upon the occurrence of the at least one sensor sensing either an input of energy from a collision with the door or an imminent collision with the door, application of energy from the energy source; at least one unit for stabilizing the door against the energy input from the collision with the door including at least one impact girder internally traversing the door which is linked with the door upon a collision to support areas within stable vehicle body areas surrounding the door and wherein; the at least one impact girder and/or support areas at least partially comprise a conversion material, the conversion material undergoing a shape change in response to the application of energy from the energy source, independent of the energy input from the collision, and producing an operational link upon the collision between the at least one impact girder and the support areas.
