Abstract
The invention relates to an unlocking device (), especially for a vehicle protection device, comprising a locking bar () which in a locked position establishes a connection positive at least in portions between a first component () to be unlocked and a second component () and permits relative motion of the two components () in an open position. The unlocking device () further comprises a pyrotechnical actuator () including a pyrotechnical element () having a propelling charge and a piston-cylinder unit () having a piston () and a cylinder (), wherein motion of the piston () or the cylinder () can be generated due to activation of the propelling charge upon ignition thereof and wherein the piston-cylinder unit () is connected to the locking bar () without redirection so that upon motion of the piston () or the cylinder () the locking bar is movable from its locked position into its open position.
