Abstract

The present invention relates to a belt tensioner (1) for a seatbelt, with a piston (2) which is arranged displaceably in a cylinder (3). Furthermore, the belt tensioner (1) has a traction transmission means (6) which is connected fixedly at one end to a displacement element (5) and at the other end to the seatbelt. It is essential here for the invention that a sealing sleeve element (7) is provided, in which the traction transmission means (6) is guided and on which the piston (2) is mounted in an axially displaceable manner, wherein the sealing sleeve element (7) penetrates the piston (2) axially and is connected fixedly at a first end (8) to a cylinder end wall (9) of the cylinder (3) while it projects at a second end (10) coaxially into the cylinder (3).
