Abstract: A tensioner device for a seat belt with a tensioner block (1) cable passageway (2) in which there is formed a pressure chamber (3) and a pull cable (4) that can be connected to a compressed-gas powered piston and that can be connected to a seat belt component for providing a tensioning motion. The pull cable extends through the pressure chamber (3) and with a gas generator (5) that is attached to the tensioner block (1), wherein, when triggered, the gas exiting from the gas generator (5) flows through a feed section (6) of the tensioner block (1) into the pressure chamber (3), wherein a guide element (8) is formed in a transition area (7) of the feed section (6) in the pressure chamber (3) that extends via a bar (11) parallel relative to the pull cable (4) and thereby divides the transition area (7) into at least two openings (9).
