Abstract: An automatic brake for a ski comprises a resiliently deformable wire of generally U shape and having a pair of pivot portions which extend parallel to the upper face of the ski and at an acute angle to the longitudinal axis of the ski. These portions are pivoted in a support plate and actuation portions extending back from the pivot portions allow the wire to be deformed and flattened out in a planar manner on top of the ski. Brake elements are carried on this wire so that when it is stepped on and flattened out these brake elements lie on top of the ski out of the way, but when a skiboot is taken off the wire they spring down and project beyond the lower face of the ski so as to prevent it from sliding.

Abstract: A ski boot clamping device comprises a ski clamp mounting plate which has an end with a raised portion forming a hook. The boot clamp has a first portion which is adapted to extend across the ski for engagement with the rear end of the boot and which has a skirt which has an engagement end which is engageable behind the plate raised portion with the hook. The boot clamp also has a second portion which is rotatably mounted in a cylindrical formation on the side of the ski and it is biased by a spring so that when the first portion becomes released from the boot, the first portion is rotated by rotation of the second portion at least over 180.degree. so that it extends downwardly into engagement with the snow so as to hold the ski against movement.

Abstract: A device for stopping a runaway ski from sliding down a hill after a skier has fallen and the ski has been released from the skier's foot. Provision is made so that the ski will not be released from the skier's foot in a static drop situation, such as where the ski accidentally comes loose from the skier's foot while the skier is riding on a lift, but will be released in a dynamic release situation, such as where the skier falls while skiing.

Abstract: A brake for a ski has a holder defining a pivot transverse to the ski and parallel to the upper surface thereof. A resiliently deformable wire has a central bight portion defining a plane, a pair of pivot portions confined in the holder pivot and bent inwardly toward each other out of the plane of the bight portion, a pair of connecting portions bent away from the pivot portions and extending outwardly away from each other toward the sides of the ski and a pair of leg portions extending generally parallel to each other from the connecting portions and lying out of the plane. The wire is symmetrical about a plane perpendicular to the surface and extending longitudinally of the ski. A braking element is carried on each of the leg portions, and is displaceable between a position in which it projects below the lower surface of the ski and a position in which it lies above this lower surface and within the lateral outline of the ski on displacement of the bight portion by the heel or toe of a skiboot.
