ABSTRACT:
An emergency locking safety belt retractor reel device includes a U-shaped bracket and a belt take-up reel rotatably supported between the side walls and spring biased to rotate in a belt retraction direction and including a shaft projecting beyond a side wall. A first circular brake member having annularly spaced brake openings is affixed to the shaft proximate the inside face of a side wall and a second brake member is axially movably mounted on the shaft proximate the side wall outer face and includes longitudinally projecting fingers movable through guide openings in the side wall into engagement with the brake reel openings to brake the reel and being spring retracted. A mechanism responsive to emergency conditions advances the second brake member which has openings with radial edges and the mechanism includes an internally toothed ratchet wheel rockable on the shaft and having inwardly projecting cam fingers engaging the second brake member radial edges, an inertia wheel rotatable on the shaft within the ratchet wheel and carrying a swingable pawl provided with a follower and a cam affixed to the shaft and engaged by the follower so that upon rapid belt extraction acceleration of the reel, the inertia wheel lags the cam in rotation to cam advance the pawl into engagement with the ratchet wheel to rock the latter which advances the second brake member to effect the locking of the first brake member and the reel.
