Ski binding

Claim 1

A safety binding for ski-boots comprising: a base fixed on a ski; a jaw pivotally mounted on said base and adapted to be alternately raised and lowered relative to said base; said jaw having a front face which is arranged to be in contact with said ski-boot and a rear face opposite to said ski-boot; a movable member slidably mounted on said base for moving lingitudinally of said ski and having front and rear ends, said front end being in abutment against said rear face of said jaw and said rear end receiving one end of a spring, the opposite end of which is applied against a part of said base; a lever pivotally mounted on said base and adapted to be vertically moved between two positions; said lever being connected to said movable member whereby: in one of said positions of said lever, said lever has no action on said movable member placed in abutment on said jaw for holding said jaw in the lowered position; in the other of said positions of said lever, said lever moves said movable member against the action of said spring to thereby free the jaw and permit said jaw to be lifted; said base, said movable member, and said lever being three elements adapted to be in displacement relative to one another; a first locking means provided on one of said elements in relative displacement; a second locking means provided on another of said elements in relative displacement; said first and second locking means coacting for securing said movable member relative to said base when said movable member is moved away from said jaw of a predetermined amplitude under the action of said lever; and unlocking means coacting with a part of the binding in contact with the boot for automatically unlocking said first and second locking means and to abandon said movable member to the action of said spring when said rear face of said jaw is facing said front end of said movable member.
