Safety ski binding

A safety ski binding including:

• a. a support means connectable to a ski for movement relative to said ski in two directions which are perpendicular to each other;
• b. a boot retaining member rotatably connected to the support means for movement into and out of engagement with a ski boot at the heel and/or toe thereof;
• c. a linkage system disposed in a two link toggle arrangement, one link of said toggle arrangement having one end thereof rotatably connected to the boot retaining member through a first axle, the other end of said one link being rotatably connected to one end of the other link of the toggle arrangement through a second axle, and the other end of said other link being rotatably connected to the support means through a third axle;
• d. a toggle link biasing means acting between the first and third axle to force the second axle into an overcenter and locked position or an undercenter and released position depending upon the line of action of the force imposed by the toggle link biasing means in relation to the position of the second axle;
• e. biasing means for resisting the displacement of the support means relative to the ski in both of said two directions;
• f. actuated means movable into engagement with the linkage system for moving the second axle from its overcenter position in which it forces the retaining member against the boot to retain the boot on the ski to its undercenter position for releasing the retaining member from the boot when the support means moves a certain distance in either one or both of said two directions relative to the ski.
