A winding assembly for a vehicle safety belt system is provided with a belt rolling device and a high speed turning device adapted upon actuation of a propellant charge to wind the safety belt at high speeds as a result of the generation of pyrotechnical gases. The high speed turning device and the belt rolling device are interconnected when a given rate of vehicle deceleration is achieved and the high speed turning device is constructed with a rotatably mounted shaft, a pair of annular chambers extending about the shaft, a pair of vanes affixed to the shaft each extending into one of the annular chambers, a first blade fixed within one of the annular chambers and arranged to be engaged by one of the vanes and a second blade extending into the other of the annular chambers and arranged to be engaged by the other vane with the second blade being mounted in driving relationship through the interconnecting means to impart driving rotation of the shaft to the belt rolling device when the high speed turning device is driven by the pyrotechnical gases. The fixed blade is adapted to engage the first vane in order to stop rotation of the vanes and winding of the safety belt. |
