Abstract
A component of a safety system in motor vehicles comprises a core which has end and side faces and is made of an explosive material. The component further comprises a jacket made of a solid semiconductor material that surrounds the explosive material on the side faces of the core, and an ignition element situated between electric contact surfaces on one of the end faces of the core. The ignition element initiates an ignition of the explosive material when current flows through it. The explosive material consists of a porous fuel and of an oxidizer incorporated into the porous fuel. The porous fuel and the solid semiconductor are made of the same material.
