Abstract
A seat belt retractor includes a main spring which urges rotation of a lap belt reel in the direction to wind the lap belt taut about the occupant lower torso. The shoulder belt reel is drive coupled to the lap belt reel for rotation therewith in the belt winding direction by the main spring to also hold the shoulder belt taut against the occupant. The drive coupling mechanism acting between the shoulder belt reel and the lap belt reel includes a lost motion connection and an auxiliary spring of lesser effort than the main spring which cooperate to permit a range of futher unwinding rotation of the shoulder belt relative to the lap belt reel. Thus, while the seat occupant lower torso remains stationary in the seat, the upper torso may lean forward against the lesser effort of the auxiliary spring as necessary to reach vehicle controls.
