Abstract
Abstract Safety ski binding. The ski binding is normally held in engaged position by resilient means such as coil springs and is convertible against said resilient means to a condition for freeing the ski boot by electrically energizer means. An acceleration responsive switch is associated with the binding to energize the boot freeing means upon the occurrence of a predetermined change in velocity of the ski binding and means associated therewith.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
In a ski binding adapted to automatically release a ski boot upon the occurrence of an overload, for example, during a fall, said ski binding having an electromagnet for releasing the binding arranged in a circuit which is supplied by a battery the power of which is controlled by a contact device, wherein the improvement comprises an acceleration sensitive device having a contact arranged on a resilient rod, said contact being provided within a second contact spaced therefrom that at a predetermined acceleration change through a movement of the resilient rod said contacts effect a control of said electromagnet.
Claim 2
Dependent Claim
99 words
In a ski binding adapted to automatically release a ski boot upon the occurrence of an overload, for example, during a fall, said ski binding having an electromagnet for releasing the binding arranged in a circuit which is supplied by a battery the power of which is controlled by a contact device, wherein the improvement comprises an acceleration sensitive device having a contact arranged on a resilient rod, said contact being provided within a second contact spaced therefrom that at a predetermined acceleration change through a movement of the resilient rod said contacts effect a control of said electromagnet.
Claim 3
Dependent Claim
25 words
The improvement according to claim 1, wherein the spacing between the resilient contact and the contact surrounding it is of different magnitude in different directions.
Claim 4
Dependent Claim
23 words
The improvement according to claim 2, wherein the resilient contact is constructed circularly and is arranged eccentrically within a circularly constructed second contact.
Claim 5
Dependent Claim
19 words
The improvement according to claim 2, wherein at least one of the two contacts is of a non-circular shape.
Claim 6
Dependent Claim
101 words
In a ski binding adapted to automatically release a ski boot upon the occurrence of an overload, for example, during a fall, said ski binding having an electromagnet for releasing the binding arranged in an electrical circuit which is supplied by a battery the power of which is controlled by a contact device, comprising the improvement wherein said contact device consists of a sensing means responsive solely to acceleration forces on the ski and being completely free of responsiveness to forces generated as a result of the position of the ski relative to the ground to directly control the ski binding.
Claim 7
Dependent Claim
101 words
In a ski binding adapted to automatically release a ski boot upon the occurrence of an overload, for example, during a fall, said ski binding having an electromagnet for releasing the binding arranged in an electrical circuit which is supplied by a battery the power of which is controlled by a contact device, comprising the improvement wherein said contact device consists of a sensing means responsive solely to acceleration forces on the ski and being completely free of responsiveness to forces generated as a result of the position of the ski relative to the ground to directly control the ski binding.
Claim 8
Dependent Claim
21 words
The improvement according to claim 5, wherein the core of said electromagnet cooperates with a release lever of said ski binding.
Claim 9
Dependent Claim
25 words
The improvement according to claim 5, wherein said contact device and said electromagnet is mounted within a housing forming a part of said ski binding.
Claim 10
Dependent Claim
69 words
The improvement according to claim 5, wherein said sensing means includes an acceleration responsive switch responsive solely to acceleration forces on said ski and being completely free of responsiveness to forces generated as a result of the position of the ski relative to the ground and integrator circuit connected in series therewith, said switch and said integrator circuit being connected in a loop between said battery and said electromagnet.
Claim 11
Dependent Claim
83 words
The improvement according to claim 5, wherein said sensing means includes an acceleration responsive switch responsive solely to acceleration forces on said ski and being completely free of responsiveness to forces generated as a result of the position of the ski relative to the ground and a series connected differentiator circuit and discriminator circuit connected in series with said switch, said switch and said series connected differentiator circuit and said discriminator circuit being connected in a loop between said battery and said electromagnet.
