The reel mechanism for vehicle safety belts comprises a means of reducing the return force of the seat belt when it is in use. This includes a ratchet which is interrupted by the revolving shaft on which the safety belt unrolls. Two retracting devices are used, one applying a continuous return force to the belt when it is being worn by a passenger. The second acts through an intermediate arrangement which tends to roll up the belt inside the reel housing. This releases some of the energy required to retract the belt while working in conjunction with the first device. |
