ABSTRACT:
A winding shaft in a belt roll-up device which has a locking element connected to the winding shaft and a blocking element fastened to the housing. The locking element comes into engagement with the blocking element by a force in the direction of the belt pull exerted upon the winding shaft such as occurs when the belt unwinds too rapidly. The belt is also prevented from completely unwinding by fastening the end of the belt to the winding shaft and by means for exerting a force on the winding shaft for making the locking element respond and engage the blocking element when the last approximately 530.degree. of turns of belt begin to unwind. Thus unwinding of about the last 1 1/2 turns of belt is prevented. This relieves the possible load and damage to the fastening of the end of the belt and to the winding shaft and permits a more economical, efficient design.
