Title: Constant torque spring for seat belt reel - has spring loaded cable wound on conical spool to compensate changing dia. of reel
Inventor: BUFLER ERNST DIPL ING
IPC: B60R22/44
Filed: 1977-08-10
Abstract: The retractor spool(3) is seated in a U-shaped frame(2). To obtain uniform tension from the retractor mechanism over the entire uniform tension from the retractor mechanism over the entire travel of the belt during pulling-out, a conical spool(7) receives the cable(8). The cable is led over a spring(9). When relaxed, the spring acts on a max. radius of the conical spool. As the seat belt is pulled out the cable travels on the windings of the spool towards the smaller radii, but at the same time the force of spring increases, producing a uniform torque on the belt reel.
