Abstract
Abstract A safety ski binding whereby a ski is secured detachably to a ski boot including an electrical or electronic device connected to a supply of electricity. A switch is located between the device and supply and includes a moveable part which is actuated automatically when the ski is fitted to the boot or removed from the boot. The switch may either be a normally open switch or a normally closed switch.

Sports equipment which can be fitted on the feet, comprising at least one device for retaining a boot or shoe on said equipment, an electrical supply source, at least one electrical or electronic device connected to said electrical supply source, and switch means located between the electrical or electronic device and the supply source for selectively connecting the same together electrically, said switch means including a movable part controlling electrical connection between the supply source and the electrical or electronic device, and means mounting the movable part for being actuated by the foot at the time of fitting of the boot in the retaining device and at the time of any removal of the boot from the retaining device.
Claim 2
Dependent Claim
119 words
Sports equipment which can be fitted on the feet, comprising at least one device for retaining a boot or shoe on said equipment, an electrical supply source, at least one electrical or electronic device connected to said electrical supply source, and switch means located between the electrical or electronic device and the supply source for selectively connecting the same together electrically, said switch means including a movable part controlling electrical connection between the supply source and the electrical or electronic device, and means mounting the movable part for being actuated by the foot at the time of fitting of the boot in the retaining device and at the time of any removal of the boot from the retaining device.
Claim 3
Dependent Claim
78 words
Equipment according to claim 1, in which the retaining device comprises a safety binding and the electrical or electronic device comprises a circuit controlling the release of the safety binding, said switch means automatically supplying the circuit for controlling the release, at the time of fitting of the equipment, the switch means normally being open and being mounted by said mounting means at a point where the boot presses, so that it can be actuated by this boot.

Claim 9
Dependent Claim
33 words
Equipment according to claim 2, in which the equipment is a ski and the switch means is actuated by a feeler actuated by the boot at the time of fitting of the ski.
Claim 10
Dependent Claim
27 words
Equipment according to claim 2, in which the switch means is actuated by the safety binding subsequent to its movement at the time of fitting the equipment.
Claim 11
Dependent Claim
39 words
Equipment according to claim 2, in which the equipment is a ski and the switch means is actuated by at least one movable part of the safety binding subsequent to its movement at the time of fitting the ski.
Claim 12
Dependent Claim
40 words
