A front piece for safety ski bindings having a sole holder adapted to be pivoted sideways against the force of a spring and serving to support the ski boot sole sideways and towards the front, a pedal for actuating a control mechanism which maintains the release resistance at least approximately constant and independent of the variable pressure applied to the pedal.

Front-piece for a safety ski-binding

A toe piece for holding a ski boot in a safety ski binding wherein the toe piece is pivotable laterally against a biasing force when excessive side forces occur. The toe piece is comprised of a base plate mountable to the upper surface of a ski, a first pivot pin mounted to the base plate, the first pivot pin being disposed to one side of the longitudinal axis of the ski and being perpendicular to the surface thereof, a holding device for holding the sole of the boot, the holding means including an elongated, arcuate opening for receiving one end of the first pivot pin therein, a second pivot pin mounted to the holding means for movement therewith, the second pin being parallel to the first pin and disposed on the other side of the longitudinal axis, a generally elongated link member pivotally mounted at one end to the first pivot pin and pivotally mounted at the other end to the second pivot pin, the link member extending genrally transversely to the longitudinal axis, an elastic device for biasing the soleholder to a central position wherein the soleholder is symmetrically disposed with respect to the longitudinal axis, and a stop member fixed to the base plate operable to cause the soleholder to pivot about the first pivot pin when the boot exerts an outward force in the direction of the first pivot pin, and to pivot about the second pivot pin when the boot exerts an outward force.

Toe piece for safety ski binding

A heel piece of a safety ski binding, said heelpiece comprising: a base attachable to a ski; opposed vertical support members mounted on said base, each support member including a track formed by an outwardly curved surface terminating in first and second end surfaces extending at an angle thereto; a soleholder mounted on said support members for pivotal movement about an axis transverse to said support members between a closed position for securing a ski boot and an open position for releasing said ski boot, said soleholder including a track formed by an inwardly curved surface terminating in first and second end surfaces extending at an angle thereto, said inwardly curved surface being contiguous with said outwardly curved surface and movable relative thereto such that said sole holder end surfaces are movable past said end surfaces of said support members; a first movable roller operable to engage said first end surfaces and said curved surfaces of said support members and said soleholder; a second movable roller operable to engage said second end surfaces and said curved surfaces of said support members and said soleholder; tension means disposed between and connected to said first and second rollers for biasing said rollers toward each other, said rollers being maintained in a spaced apart location by said respective surfaces of said support members and said soleholder wherein said first roller is movable between engagement with said first end surface of said soleholder and said first end surface of said support members as said soleholder moves between said closed position and said open position, said tension means exerting a biasing force on said soleholder to maintain said soleholder in said closed position when said first roller is in engagement with said first end surface of said soleholder, and lever means pivotally mounted on said support members, said lever means including a cam slot for receiving and guiding the ends of said first roller, said lever means being members operable to move said first roller from engagement with said first end surface of said soleholder when said soleholder is in the closed position to engagement with said first end surfaces of said support members when said soleholder is in the open position wherein said second roller engages said second end surface of said support member when said soleholder is in said closed position, and wherein said second roller engages said second end surface of said soleholder when said soleholder is in said open position.
