Document Type and Number:
Japanese Patent JPS5326369
Kind Code:
B2
Abstract:
An automatic locking vehicle safety belt retractor includes a shaft on which is affixed a belt take up reel having similar first ratchet wheels at its opposite ends. A spring retracted transverse pawl member includes pawl teeth which are rockable with the pawl member into and out of braking engagement with the ratchet wheels and the pawl member is drive coupled to an internally toothed second ratchet wheel rockably mounted on the shaft. A fly wheel is freely rotatable on the shaft within the second ratchet reel and carries a spring retracted second pawl swingable into engagement with the second ratchet wheel and a cam wheel is rotatable with the shaft and engages a cam follower on the second pawl to advance the second pawl upon rotation of the cam wheel relative to the fly wheel. The numbers of teeth on the second ratchet wheel and on each of the first ratchet wheels are equal and the cam and ratchet wheels are so angularly related that when the retractor is braked, the pawls fully engage respective ratchet teeth.
