ABSTRACT:
A safety ski binding comprised of first and second jaw units for retaining a ski boot on the ski. The first jaw unit includes a contact switch, which will be actuated in response to predetermined forces which are transmitted from the ski boot to the first unit, the forces being transmitted in at least two planes which are at right angles to each other. The first jaw unit includes an axle mounted to a base plate, a cam surface on the axle, a boot holder mounted on the axle for rotational axial movement thereon, a first spring operable to bias the boot holder into rotation about the axle, a second spring disposed between the axle and the boot holder operable to bias the boot holder to a central position on the axle, a pin which is parallel to the transverse axle and held on the base plate, and a control lever rotatably and axially movable on the pin controlling a release mechanism for holding the ski boot on the ski. The control lever has a first lever end engaging a cam surface on the axle and a second end operative to engage the boot holder wherein the boot holder engages the second lever end that imparts rotational movement to the control lever when the boot holder moves from a first boot holding position toward a second boot release position. The control lever is arranged to move axially with the soleholder as the soleholder moves along the axle wherein the first lever end moves along a cam surface which imparts rotational movement to the control lever.
