Abstract
Abstract An improved stability safety binding of the type in which all degrees of movement of a ski boot relative to a ski are releasably resisted without requiring the use of a toe fastening device. A unitary safety release mechanism spring-biases upwardly and inwardly directed clamping arms into engagement with flanges at the sides and rear of the ski boot. The rear clamp resists rearward longitudinal movement of the boot, and the side clamps are inclined in an outwardly and rearwardly direction to resist forward longitudinal movement of the boot.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A safety binding adapted to releasably resist longitudinal, lateral, twisting and heel-lifting movement of a ski boot relative to a ski without requiring the use of a toe-fastening device, comprising: means adapted to secure said ski boot to said ski at a point of engagement located forwardly of the rearward end of said ski boot and rearwardly of the point of application of heel-lifting force; means adapted to secure said ski boot to said ski at the rear of said ski boot; and safety release means coupled to said last two named means for releasing the engagement of said last two named means for releasing the engagement of said last two named means upon the transmission of excessive force by said ski boot.
Claim 2
Dependent Claim
123 words
A safety binding adapted to releasably resist longitudinal, lateral, twisting and heel-lifting movement of a ski boot relative to a ski without requiring the use of a toe-fastening device, comprising: means adapted to secure said ski boot to said ski at a point of engagement located forwardly of the rearward end of said ski boot and rearwardly of the point of application of heel-lifting force; means adapted to secure said ski boot to said ski at the rear of said ski boot; and safety release means coupled to said last two named means for releasing the engagement of said last two named means for releasing the engagement of said last two named means upon the transmission of excessive force by said ski boot.
Claim 3
Dependent Claim
41 words
