Abstract
Abstract A safety ski binding system comprises a heel-hold device and an abutment mounted on the ski as well as the sole of the skiing boot. The heel-holding device normally forces the sole of the boot against the abutment and in response to a vertically and/or horizontally directed overload releases the skiing boot. The abutment consists of a disc, which is secured to the ski to be at least approximately coaxial to the tibia and when the skiing boot is applied extends into a corresponding recess in the sole of the boot.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
A safety ski binding system comprising a disc-shaped abutment mounted on a ski in a position adapted to be approximately coaxial to the tibia of the skier, a skiing boot having a recess in a sole thereof, a hood including at least one resilient clamp member, said hood and abutment being adapted to extend into said recess in the sole of said skiing boot, said abutment carrying an upstanding detent pin adapted to interlock with said at least one resilient clamp member, and locking means for securing said hood to said skiing boot so that said hood can be only arbitrarily unlocked, said hood adapted to cooperate with the sole of said skiing boot to force said sole against said abutment and to release said boot in response to a predetermined overload force.
Claim 2
Dependent Claim
133 words
A safety ski binding system comprising a disc-shaped abutment mounted on a ski in a position adapted to be approximately coaxial to the tibia of the skier, a skiing boot having a recess in a sole thereof, a hood including at least one resilient clamp member, said hood and abutment being adapted to extend into said recess in the sole of said skiing boot, said abutment carrying an upstanding detent pin adapted to interlock with said at least one resilient clamp member, and locking means for securing said hood to said skiing boot so that said hood can be only arbitrarily unlocked, said hood adapted to cooperate with the sole of said skiing boot to force said sole against said abutment and to release said boot in response to a predetermined overload force.
