Abstract
An inhibitor intended for the prevention of early reel lock-up during door opening for passive vehicle safety belt systems incorporating door-mounted reels. In such systems where a high inertia mass moves a pawl into engagement with the take-up reel during emergency conditions thereby allowing freedom of occupant movement during other periods of time, biasing means are provided for resisting the movement of the high inertia mass/pawl combination when the vehicle door is in the process of being opened and closed. Embodiments disclosed include the use of a selectively activatable electromagnet, a movable permanent magnet, gravitational biasing of the pawl, spring biasing of the pawl, and spring biasing of the high inertia mass.
