Abstract
Abstract A ski binding is held in normal operating position by releasable, mechanical parts and is preferably urged into such position by resilient means. A rotatable electric motor is mounted in association with such ski binding and is provided with suitable means responding to activation of the motor for withdrawing said mechanical parts against said resilient means out of holding position. Said motor may be activated in any convenient manner, as manually by the closing of a switch by the skier or by remote control or automatically in response to bioelectrical currents within the muscles of the skier.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
204 words
In a releasable ski binding for holding a ski boot on a ski, said releasable ski binding having a base secured to said ski, a ski boot engaging member supported for movement relative to said base between a boot engaging and a boot release position and movable lock means defining a threshold force value for releasably holding said ski boot engaging member in said boot engaging position when forces are applied to said ski binding by said ski boot which are below said threshold force value and permitting a release of said ski boot when forces are applied to said ski binding which are above said threshold force value, the improvement comprising: electrical rotary driven means having a rotary output and electrical power source means therefor; connecting means for mechanically connecting said rotary output to said releasable lock means; and switching means for controlling the supply of electrical power from said electrical power source means to said electrical rotary driven means to effect a rotation of said rotary output and a mechanical movement of said movable lock means and thereby a release of said ski binding from said boot engaging position separate from said forces applied by said ski boot to said ski binding.
Claim 2
Dependent Claim
204 words
In a releasable ski binding for holding a ski boot on a ski, said releasable ski binding having a base secured to said ski, a ski boot engaging member supported for movement relative to said base between a boot engaging and a boot release position and movable lock means defining a threshold force value for releasably holding said ski boot engaging member in said boot engaging position when forces are applied to said ski binding by said ski boot which are below said threshold force value and permitting a release of said ski boot when forces are applied to said ski binding which are above said threshold force value, the improvement comprising: electrical rotary driven means having a rotary output and electrical power source means therefor; connecting means for mechanically connecting said rotary output to said releasable lock means; and switching means for controlling the supply of electrical power from said electrical power source means to said electrical rotary driven means to effect a rotation of said rotary output and a mechanical movement of said movable lock means and thereby a release of said ski binding from said boot engaging position separate from said forces applied by said ski boot to said ski binding.
Claim 3
Dependent Claim
83 words
The improvement according to claim 1, wherein electrical rotary driven means is a stationary electrical motor having said rotary output and drum means mounted thereon for rotation therewith; and wherein said connecting means comprises a flexible cable wound on said drum means at one end and being connected to said movable lock means at the other end, a rotation of said drum means effecting a winding of said cable onto said drum means and a resulting mechanical movement of said movable lock means.
Claim 4
Dependent Claim
105 words
The improvement according to claim 2, wherein said releasable lock means comprises a movable locking member movable between first and second positions and engaging a portion of said ski boot engaging member when in said first position, resilient means for urging said locking member toward said first position; and wherein said other end of said cable is connected to said locking member whereby a rotation of said drum means effects a winding of said cable onto said drum means and a resulting movement of said locking member to said second position against the urging of said resilient means to thereby release said releasable ski binding.
Claim 5
Dependent Claim
24 words
The improvement according to claim 3, wherein said ski boot engaging member is pivotally mounted on said base for movement about a horizontal axis.
Claim 6
Dependent Claim
24 words
The improvement according to claim 3, wherein said ski boot engaging member is pivotally mounted on said base for movement about a vertical axis.
Claim 7
Dependent Claim
29 words
The improvement according to claim 3, wherein said ski boot engaging member is pivotally mounted on said base for movement about both a horizontal axis and a vertical axis.
Claim 8
Dependent Claim
16 words
The improvement according to claim 3, wherein said locking member is pivotal about a horizontal axis.
Claim 9
Dependent Claim
17 words
The improvement according to claim 3, wherein said locking member is reciprocally slidable along a horizontal axis.
Claim 10
Dependent Claim
123 words
The improvement according to claim 2, wherein said releasable lock means comprises a pair of normally aligned permanent magnets each having pole faces of opposite polarity, one of said permanent magnets being secured to one of said base and said ski boot engaging member, the other of said permanent magnets being slidably mounted to the other of said base and said ski boot engaging member for reciprocating movement; and wherein said other end of said cable is connected to said other permanent magnet whereby a rotation of said drum means effects a winding of said cable onto said drum means and a resulting movement of said other permanent magnet so that said pole faces become unaligned to thereby release said releasable ski binding.
Claim 11
Dependent Claim
20 words
The improvement according to claim 9, including resilient means for urging said other permanent magnet to said normally aligned arrangement.
Claim 12
Dependent Claim
30 words
The improvement according to claim 1, wherein said electrical power source means comprises a battery; and wherEin said switching means is a normally open switch mounted in a ski pole.
Claim 13
Dependent Claim
49 words
The improvement according to claim 1, wherein said switching means comprises a transmitter for automatically generating an electrical signal in response to a fall condition and receiver means responsive to said signal to effect an electrical connection of said electrical power source means to said electrical rotary driven means.
Claim 14
Dependent Claim
14 words
The improvement according to claim 1, including means for adjusting said threshold force value.
