Abstract

Safety belt reeling means with a tightening device comprising a drive which is activated in the event of an incident is provided. The drive is spaced from a belt winding spindle of the belt reeling means and is connectable thereto via a coupling in the event of actuation of the drive. The coupling comprises a first coupling member which is mounted on a driven disc so as to be capable of movement, in the event of rotation of the disc, to engage with a second coupling member connected to the belt winding spindle, the driven disc being constructed as an inertia disc which is adapted to be set in rotation by the drive. Preferably the drive is a piston/cylinder unit which transmits a rotary motion to the inertia disc via a piston rod and a crank pin.
