Abstract
A device for locking the webbing for the seat belt of an automotive vehicle is provided with a webbing reel biased in a direction to wind the webbing, a drum on which the webbing is partially wound, a drum base supporting the drum and having an axis of rotation eccentric from the axis of rotation of the drum, and a base supporting the reel and drum base. A fixed plate is provided on the base with a sufficient distance with respect to the drum to permit the webbing to pass therethrough, and a sensing device sensing a sudden shock or acceleration or deceleration of the vehicle is also provided. Means are provided for preventing rotation of the reel and the drum when a sudden shock or acceleration or deceleration has been imparted to the vehicle, and means for rotating the drum base at its eccentric axis of rotation to press the drum into contact with the fixed plate and intensely tighten the webbing therebetween is provided to thereby impede the draw-out of the webbing by the tightening thereof. The means for preventing rotation of the drum is fixed to the drum base, and the drum is mounted for movement relative to the drum base.
