Abstract
A pyrotechnical actuator has a cylindrical housing surrounding a hollow chamber and a piston movably supported in the cylindrical housing. A piston rod is connected to the piston. A detonator is arranged within the hollow chamber and configured to produce a quantity of gas for moving the piston from an initial position in the cylindrical housing into an end position. The piston rod triggers an action when the piston moves into the end position or is positioned in the end position. The cylindrical housing is divided in a longitudinal direction of the cylindrical housing into housing parts. At least one holding element secures the housing parts relative to one another.
