ABSTRACT:
A heel piece of a ski safety binding which automatically opens when an excessive force is exerted on the ski boot. The heel piece includes a pair of arms pivotally connected to a base plate, a frame pivotally connected to a pivot pin extending between the pair of arms, which frame is displaceable along the axis of the ski, a heel holding member provided at the front end of the frame and a lock piece disposed in the frame and being displaceable along the axis of the ski relative to the frame. The lock piece has a cam surface which engages a lock pin provided between the pair of arms in a normal state of use. When a strong upwardly directed force is applied to the heel holding member as in a case of a forward fall of the skier, the frame and lock piece displace rearwardly and thereby brings the lock pin out of engagement with the cam surface of the lock piece, enabling the heel piece to rotate for releasing the heel of the ski boot. A release load can be adjusted by varying space defined between the frame and the lock piece.
