Solid fuel body, gas generator, module having a gas generator, and pyrotechnic drive unit

An individual protection system for vehicles comprising:

• a combustion chamber extending along a longitudinal axis and in which a plurality of solid propellant compacts are provided;
• and
• an igniter that is electrically actuatable to ignite the plurality of solid propellant compacts to actuate the individual protection system, each compact of the plurality of solid propellant compacts comprising a solid mass of powdered or granulated solid propellant having a cylindrical outer side wall centered along a longitudinal axis, and spaced first and second end walls through which the central longitudinal axis extends, the side wall and the first and second end walls defining an entire outer surface of the solid propellant compact, at least one of the first end wall and the second end wall includes at least one recess, at least one of the plurality of solid propellant compacts being free from bores that extend through the solid mass of powdered or granulated solid propellant, wherein the plurality of solid propellant compacts are disposed randomly in the combustion chamber so that the central longitudinal axes of the solid propellant compacts are predominantly offset from the longitudinal axis of the combustion chamber and from each other such that the central longitudinal axes are predominantly noncollinear.
