ABSTRACT:
A belt retractor for incorporation in a fold-down type backrest of a vehicle seat is disclosed. The backrest of the seat is able of being latched to a vehicle body in an upright seating position by a lock. The retractor has a frame and a belt reel rotatably mounted in the frame. A blocking mechanism is provided for selectively blocking rotation of the belt reel on the frame. The blocking mechanism is activated as long as the backrest is not locked in place by latching action of the lock. The blocking mechanism comprises an activating means responsive to inertial forces. The activating means has a coupling disk which is connected to the belt reel and has a coupling toothing. The activating means further has a coupling pawl which can be caused to engage the coupling toothing. The coupling pawl comprises a control knuckle coupled by a traction means to the lock.
