Abstract
Abstract Safety release bindings for action between a ski and a ski boot. Means are provided for utilizing muscular stress of the skier and utilizing a preselected value of same for releasing the binding. In certain embodiments, the muscular stress is measured by the bio-electrical output of the skier''s muscles. In other embodiments the muscular stress is measured by physical movement of the skier''s foot within or with respect to his ski boot. In one embodiment, a primary measurement is made of such muscular stress while a secondary measurement is made of the stress between the ski boot and the ski, both of said stresses being required to coincide in order to release the ski.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
In a safety ski binding which releases the ski shoe worn by a skier from the ski when an overload or stress condition occurs, the improvement comprising: at least one signal generator mounted on one of said ski shoe and a limb of said skier and adapted to generate a first electrical signal in response to said stress condition between said ski shoe and said limb when said ski shoe is secured by said ski binding to said ski; at least one of the components of said ski binding being responsive to an electrical signal to open and permit a release of said ski shoe; at least one electrical signal receiver means responsive to said electrical signal and adapted to generate a second electrical signal in response to said first electrical signal and being connected in electrical circuit with said electrically responsive ski binding whereby said electrically responsive ski binding will release said ski shoe upon the occurrence of a second electrical signal.
Claim 2
Dependent Claim
163 words
In a safety ski binding which releases the ski shoe worn by a skier from the ski when an overload or stress condition occurs, the improvement comprising: at least one signal generator mounted on one of said ski shoe and a limb of said skier and adapted to generate a first electrical signal in response to said stress condition between said ski shoe and said limb when said ski shoe is secured by said ski binding to said ski; at least one of the components of said ski binding being responsive to an electrical signal to open and permit a release of said ski shoe; at least one electrical signal receiver means responsive to said electrical signal and adapted to generate a second electrical signal in response to said first electrical signal and being connected in electrical circuit with said electrically responsive ski binding whereby said electrically responsive ski binding will release said ski shoe upon the occurrence of a second electrical signal.
Claim 3
Dependent Claim
37 words
The improvement according to claim 1, wherein said signal generator comprises a bio-electrical sensing device adapted to sense the bio-electrical currents produced by said limb of said skier during muscle movements and producing said first electrical signal.
Claim 4
Dependent Claim
96 words
The improvement according to claim 2, wherein said one component of said ski binding includes a boot engaging member pivotally secured to said ski and adapted to pivot between a boot engaging position and a boot release position and means defining an electromagnet having a movable core member engageable with said boot engaging member to hold said component in said boot engaging position, said second electrical signal being adapted to energize said electromagnet to move said movable core member out of engagement with said boot engaging member to permit a pivoting of said boot engaging member.
Claim 5
Dependent Claim
45 words
The improvement according to claim 3, wherein said bio-electrical sensing device is connected in electrical circuit with a signal transmitter mounted on said ski shoe, said receiver means being adapted to receive a signal transmitted by said signal transmitter to generate said second electrical signal.
