Abstract: This invention relates to winding-in devices for automobile safety belts of the kind having a shaft, rotatably mounted in a housing to receive the safety belt, which is withdrawable, and having locking means by which said shaft is locked against further rotation in the withdrawal direction when a predetermined limiting level of angular acceleration is exceeded, and further having an inertia body, rotatable on and with said shaft, which, when said limiting level is exceeded, lags behind the rotary movement of said shaft in opposition to the effect of spring means which connect it to said shaft, in order to bring a least one locking pawl, which is mounted to pivot in a flange on said shaft, into engagement with a ring of teeth secured to said housing via a cam track.According to the invention, the locking pawl is inset in the flange on the shaft, and is connected to said flange by means of a pivot mounting having a bearing means.
