Abstract
A safety belt pretensioner in a restraining system for vehicle occupants includes a reel (54) which is provided with a slot (58) for the passage of the webbing (16) and which comprises a toothing (56) at its outer periphery. The reel (54) is arranged loosely between toothings (42, 44, 52) arranged opposite spaced apart from each other on two opposing spaced apart parallel plates (20d, 40). One of said plates forms a drive plate (40) which is displaceable along the bottom wall (20c) of a frame (20) to which the other plate (20d) is secured as cover plate. A return brake for diminishing energy peaks in the webbing system is formed by a torsion bar (32) on which a gear (34) is mounted via an overrunning clutch (36). The gear (34) is in engagement with a toothing (46) of the drive plate (40). A linear drive engages the drive plate (40) for moving the drive plate (40).
