Claim:
1. A fin deployment mechanism comprising a base unit, wherein the base unit has a flat surface, deployable fins movably arranged on the base unit, connected by an axle to the base unit and rotatable about the axle and, in a retracted position, bearing against the base unit, as well as a gas-generating device, wherein the fins in the retracted position are fixed to the flat surface of the base unit, and in that at least one gas duct is arranged in the base unit so as to conduct pressurized gas generated by the gas-generating device to a bottom side of the fins bearing in the retracted position against the base unit, in order to create a force which acts on the fins for deployment of the fins, wherein the fins are fixed to the base unit and bear against an outer radius of the base unit, and wherein the at least one gas duct is a groove or recess in the flat surface of the base unit and the length of the at least one gas duct in the longitudinal direction of the base unit is 2 to 80 times the width of the at least one gas duct.
