Reel assembly for a safety belt of an automotive vehicle

The assembly has a belt reel (1) for the safety belt, a frame (8) which can be frictionally connected to the structure of the motor vehicle, onto which the belt reel (1) is rotatably mounted and a blocking apparatus (3) which, when there is an excessive change of speed of the vehicle, is effective by engagement between the frame (8) and the belt reel (1). Between a shaft part (2) of the belt reel (1) upon which forces emanating from the belt web act, and an area of engagement (4) of the belt reel (1) with which the blocking apparatus (3) can engage, an energy absorber (5) is provided, which allows a specific extension of the belt web with simultaneous absorption of the energy transferred from the belt web. The energy absorber (5) can be activated simultaneously with an airbag (24) and includes a torsion rod frictionally received in a sleeve (6) which, in an emergency, is moved rightwards by igniting a propellant charge (9).
