A safety binding for a ski includes a jaw for holding the sole of a ski boot, the jaw being movable at least transversely with respect to the axis of the ski. The jaw is held in its normal position by an elastic member which returns it into its normal position after transverse movement. The jaw is associated with a pedal positioned under the end of the sole of the ski boot. This pedal includes a support member movable with respect to the ski as well as to the jaw.

Safety binding for ski

A safety ski binding embodying a release plate which can be secured to the ski boot, the release plate cooperating at its front and rear with resiliently yielding locking elements rendering possible release of the ski boot and release plate both upwardly and laterally. The release plate is rotatably or pivotably mounted at the ski at a point intermediate the toe and heel of the ski boot heel by means of a pivot bearing enabling raising of the release plate away from the ski. The locking elements oppose lateral release of the release plate either only at the front or at the rear, yet oppose release of the release plate upwardly away from the ski both at the front and rear.

Safety ski binding

The invention relates to a safety ski binding toe mechanism comprising a skid plate underlying the forward end of the ski boot sole. According to the invention, the skid plate, or the pivotable and longitudinally shiftable sole retainer, respectively, is provided with keying means preventing the skid plate from twisting relative to the ski boot sole at least within the elastic yield limits of the toe mechanism. The keying means may comprise a pair of guide jaws receiving the ski boot sole therebetween, or may be constituted by stop portions or projections on the upper surface of the skid plate cooperating with complementary counter stops or engagement means of the ski boot sole.

Toe mechanism for a safety ski binding

This invention relates to a release type ski binding comprising a heel retainer means and a toe retainer means between which a release plate or a ski boot sole extends, the toe retainer means having connected thereto a foot plate extending under the boot sole at least as far as the toe ball portion of the ski boot sole and, when a release movement sidewardly off the running position against the force of a sideways release means provided on the ski takes place, the release plate or the ski boot sole, respectively, being first held against forward movement by a support means and therefore being only pivotable sideward about a pivot point disposed in the heel area, and the foot plate being adapted to slide away from the heel retainer means in the longitudinal direction of the ski when an elastic range has been exceeded, and further comprising a friction-reducing rest means for the pivot motion. Under particular tumbling conditions different reaction forces occur in the ball area of the ski boot and impede the release of the ski boot. Different oriented reaction forces are prevented by the fact that exclusively the foot plate is directly supported by the rest means with a view to the pivoting and sliding motions.

Release type ski binding

A sole-support plate for a release ski binding is supported on the upper side of a ski by a pivot bearing and cooperates with a resilient restoring arrangement. The restoring arrangement includes an opening provided in the sole-support plate, which plate is made of an elastic material, the opening weakening the sole-support plate in the area of the pivot bearing so that it can be swung laterally through elastic deformation of the region having the opening and will thereafter return automatically to its original position through the resilience of this region.

Sole-support plate

A releasable toe holder or toe jaw for ski bindings having a sole holder movably mounted transversely with respect to the lengthwise direction of the related ski. The sole holder is retained in a normal position by a spring element and following a limited transverse movement thereof is returned back into such normal position by said spring element. The sole holder has a pedal intended to engage beneath the sole end of the ski boot. The sole holder is anchored to the ski by means of a double guide or link arrangement coupled with the spring element. One hinge or pivot of the double guide arrangement is fixedly arranged on the ski and a second hinge or pivot engages the pedal behind the sole holder.

Releasable toe holder for ski binding

A releasable safety ski binding holding a release plate, having a safety release device secured to the ski for releasably holding the release plate to the ski. A heel holder is longitudinally non-adjustably mounted on the rear of the release plate, and a toe holder is adjustably disposed on the front of the release plate to hold different size ski boots without affecting the safety release holding of the binding. In another embodiment, the safety ski binding has a lateral and vertical safety release member only adjacent one end of the release plate, the other end of the release plate defining a vertical release pivot fulcrum. The release plate is pivotally mounted on the ski intermediate its ends, whereby different lateral and vertical release moments exist.

A heel- or sole holder arranged at a sole or release plate of a ski binding, comprising a heel holddown guided in a guide means to be movable essentially parallel to the plane of the plate. The heel holddown can be rearwardly displaced out of an operating position which it has assumed under the action of spring force, against such spring force. The heel holddown possesses at one end a deflection or diverting surface which, in the operating position of the heel holddown, overlaps or extends over the ski boot-support surface of the sole or release plate and extends in the direction of the spring force towards the sole or release plate. The guide means is structured to slope or descend towards the sole or release plate in the direction of the spring force. Further, the sole or release plate equipped with such heel holder has the latter connected with the sole or release plate by means of anchoring elements, for instance anchoring pins, engaging into transverse bores of the plate and secured in the axial direction thereof.

Heel or sole holder for a sole plate of a safety ski binding and sole

A safety ski binding wherein the ski boot is clamped between an automatic heel portion of the binding and a pivotal jaw held in its operable position by spring force. The jaw is provided with a plate which engages beneath the sole of the ski boot and is fastened to the ski by means of a spring-loaded locking element arranged forwardly thereof and a pivot bearing engaging the plate.

A release-ski binding with a release plate releasably connected with the ski boot, the release plate being releasably anchored at its both ends on the ski, characterized by a lever arrangement acting on the release plate, which on the one hand is set to be coupled with the leg of the skier above the ankle, and on the other hand stands in operative connection with a spring which tends to hold the rear end of the release plate in engagement with a holding member overlapping this end.

Release-ski binding

A ski binding with release plate which extends substantially over the entire length of the sole, mounted rotatably and liftably in the range of an extension of the axis of the leg of the skier by a pivot pin screwed on the ski, and latched or releasably locked to the side and/or upwardly at both ends by means of release mechanisms, respectively. The release plate is provided in the vicinity of the ball of the foot with a hinge which is operative only upwardly, thus away from the ski, while downwardly, toward the ski, a rigid abutment is provided.

Ski binding with release plate

A combination safety ski binding and ski shoe, with a release plate fastened on the ski at its both ends until the exceeding of a predetermined force action, the release plate being releasably connected with the shoe by a sole holder and a heel holder. The sole holder as well as the front anchorage of the release plate are rearwardly offset with respect to the tip of the shoe, wherein the sole holder has coupling mounts positively engaging in each other, and the shoe sole between the mount arranged thereon and the heel holder is formed considerably stiff.
