ABSTRACT:
An apparatus (10) for absorbing energy in the event of a vehicle collision comprises a structural member (12, 38) of a vehicle (14). A pyrotechnic device (50) is mounted adjacent to the structural member (12, 38). The pyrotechnic device (50) is actuatable to generate combustion products and to direct the combustion products into engagement with the structural member (12, 38) to weaken the structural member. The weakening of the structural member (12, 38) enables controlled deformation of the structural member in the event of application to the structural member of force exceeding a predetermined amount.
