A linear drive, especially for a belt tensioner, includes a housing () including a piston seat (), a piston element () accommodated in the piston seat () and a pyrotechnical drive element adapted to supply gas for displacing the piston element (). The inner wall of the piston seat () includes a groove () extending in the displacing direction (R) of the piston element () through which gas can flow off the piston seat ().

Linear drive

A positioning device has a deformable load-bearing element (), a shaped part () coupled to the load-bearing element (), and a holder (). The load-bearing element () is adapted to be shifted from a first position in which the shaped part () is held in a first shape by the holder (), into a second position in which the shaped part () is at least partially no longer held by the holder () and takes a second shape which is transmitted to the load-bearing element ().
