Straffer für einen Sicherheitsgurt

摘要

The tensioner comprises a piston/cylinder unit (3) that is made up of a cylinder (5) and an arranged piston (7) in its interior. There is a pressurised gas source (17) that is activated behind the piston's sliding. There is a belt gripping system (13) gripped onto the safety belt, and a pull-transmission means (11) that connects the piston with the belt gripping system. There is at least one dampening system for the absorption of energy, due to the retardation of the movement of the belt gripping system. There may be a stop (55) for the first and second piston sections (27,29), whereby the stop for the second piston section may be delayed after the stopping of the first piston section.
