Patent ID: 8316758

Claim:
A pneumatic actuator for an active hood, comprising: a cylinder; a piston movable in the cylinder between a lower terminal position, in which a volume of a chamber delimited by the piston and the cylinder, which may be impinged with a compressed gas, is minimal, and an upper terminal position, in which the volume of the chamber is maximal, and which is lockable by a detent body, which engages in a first plurality of recesses of the cylinder and the piston, in the lower terminal position; and a slider displaceable by impingement using the compressed gas out of an idle position, in which it fixes the detent body in the first plurality of recesses, into a triggering position, in which a second recess of the slider overlaps with one of the first plurality of recesses and, together with a first recess of the first plurality of recesses, is capable of accommodating the detent body, wherein the cylinder is assembled from a first part and a second part and the first recess of the cylinder is formed at a boundary between the first part and the second part.
