Abstract: An automatic passenger seat safety belt reeling device, has a steel frame (31, 32, 33) and a reel rotatable in the frame about an axis (39) which is angularly moveable about a second axis (40) offset from the first axis to effect locking of the belt, the first axis being coupled by connecting links (48) to a pivot (46) of a clamping member (47), the clamping member being thereby moveable with the angular movement of the axis (46) of the reel about yet a further axis (45) displaced from the pivot (46), the clamping member having a curved clamping surface (47a) which thereby moves towards a paying-out seat belt (61) to lockingly clamp it against a clamping plate (50) located in the frame.

Abstract: In an automatic spring biassed seat belt retract for passenger seat belts in vehicle a winding reel (15) has a coil spring (17) which winds up as the belt webbing is pulled off the reel, the reel is mounted in a frame (1) with interval teeth (30,31) in apertures (34,35) on each side (22,23) of the frame and the reel assembly is rigidly rockable about a pivot axis (26-45) displaced from the reel periphery to achieve programmed synchronized meshing of teeth (20,21) of the reel with the teeth of the apertures to lock up the reel when excessive vehicle deceleration or excessive webbing pull-out acceleration is sensed by inertia sensing means and such synchronized movement being assured by the manner of the reel mounting on a U-shaped needle arrangement (14,26,31) in the frame.
