Vehicle safety belt reel control system - has braking system to limit retraction forces when belt is uncoiled

摘要

The device for coiling or reeling up vehicle safety belts, includes a drum acted upon by a powerful spring operating in the direction in which the belt is retracted. There is a braking device (5, 7, 8) connected to and operating on the drum (2) around which the belt is coiled. The braking device (5, 7, 8) acts in such a way that it reduces the retraction forces operating on the belt as the diameter of the coil (11) of safety belt on its drum (2) is reduced.
