Patent Images
1. An apparatus for controlling a torsion bar, which limits force of seat-belt webbing paid out from a spindle, the apparatus comprising:
- a button attached to the webbing that travels in a path when the webbing is paid out;
a lever engaged by the button traveling in the path; and
a gear ring operatively coupled to the lever, wherein engaging the lever by the button rotates the gear ring to disengage a torsion-bar stiffening element.
