<p>A voluntary-ski-removal lever pivots about a first axis integral with a piston and moving therewith. By means of a ramp, this lever cooperates with a fixed axle about which a jaw pivots in such a manner that, when the lever is depressed, this movement brings the first axis and the fixed axle together, thus causing the piston to move back and to release the jaw.</p> |
