Zusammenfassung:	A linear drive, especially for a belt tensioner, includes a housing (10) including a piston seat (12), a piston element (16) accommodated in the piston seat (12) and a pyrotechnical drive element adapted to supply gas for displacing the piston element (16). The inner wall of the piston seat (12) includes a groove (30) extending in the displacing direction (R) of the piston element (16) through which gas can flow off the piston seat (12).
