ABSTRACT:
A device for winding up a safety belt is locked in response to a change of inertia of the device housing. The device includes two elements at least one of which is a rotatable member having a pulley at one end with a band wound around it. An end of the band extends from the pulley and is connected to the safety belt. One end of the rotatable member is arranged adjacent the other element in the housing. A locking member is moved by its own inertia in response to an inertial change in the device housing and is engaged between the two elements to lock rotation of the rotatable member.
