<p>16 Automatic rapid-locking belt retracting unit Describe is an automatic rapid-locking belt retracting unit having a blocking mechanism comprising an inertia force sensor (8, 9), a blocking pawl which is arranged movably by means of a holding pin, a blocking cog and a control member (5, 6) carrying the inertia force sensor (8, 9), an engagement control element (5) which is freely rotatable with respect to the winding shaft, with internal teeth (5d), for engaging the blocking pawl into the blocking cog, a control cog (6) with external teeth (6c), and a freely rotatably mounted control pawl (10) which is mounted on the control cog (6) and which has a long lever (10e) and a short lever (10f), and a rotary inertia weight (7) for actuating the blocking pawl in the event of excessive belt acceleration. For the purposes of further simplifying the overall construction and improving the performance in terms of comfort as well as relieving the mounting of the winding shaft in the housing of load, the invention provides that the control cog (6) is secured to the blocking cog and has a hollow central journal portion (16) in which the central pin of the cup-shaped engagement control element (5) is rotatably mounted.
