A sideways releasable jaw of a ski binding for holding one end of the ski boot (9) has a binding housing (11) in which a release spring (14) is arranged The release spring (14) extends substantially in the longitudinal direction of the ski and is braced at one end against the binding housing (11). At its other end it exerts a release force with a substantial component in the longitudinal direction of the ski pointing away from the ski boot (9) on a sole clamp (22) arranged towards the ski boot (9). On exceeding a predetermined sideways force exerted by the ski boot (9) the sole clamp (22) can pivot sideways about a substantially upright pivotal axis and releases the ski boot (9). In so doing the release spring exerts a downwardly directed force component on the sole clamp which is vertically displaceably arranged on the binding housing (11) for movement along an upright sliding guide. Thus the sole clamp (22) is pressed against the upper side of the sole (29) of the ski boot. The sliding guide (25, 26) has at least two sections (25', 26', 25', 26') which are differentially inclined relative to the line of action (27) of the release spring force so that an instantaneous center of rotation M is formed which is arranged at a distance a above the line of action (27) of the release spring force.

A releasable ski binding is provided with a boot holder which can be swivelled around a vertical shaft and is pushed into a normal ski boot holding position by a piston. At its end facing the boot holder, the piston is arranged to be slidable into the transverse direction with play, and at its other end, the piston is arranged to be slidable in a guide almost without play. Thus, swivel motions of the boot holder can take place largely without friction between the boot holder and the piston parts which rest against it. At the same time, the normal position is defined virtually without play.

Releasable ski binding

A heel unit of a ski binding has a housing (12) which is resiliently rearwardly deflectably mounted on the ski. A sole clamp (13) having a hold-down member (13') and a pedal element (13'), and also a hand-opening lever (15) are pivotably mounted about a transverse axis (14) in each case. The sole clamp (13) is biased by a release spring (16) into a closed position via a transmission (17, 18) having a deadpoint (26'). The sole clamp (13) can snap into an open position under the action of excessive vertical forces by moving through the deadpoint (26). The sole clamp (13) and the hand-opening lever (15) are pivotally mounted about the same transverse axis (14) which is arranged in the front region of the housing (12). Actuating abutments (19, 20) which cooperate with one another are provided at a radial distance from the transverse axis (14) and an opening moment is transmitted from the hand-opening lever (15 ) onto the sole clamp (13) via these actuating abutments.

Heel unit for a ski-binding

A ski binding is disclosed for supporting a ski boot in the downward direction by a plate-type bearing part which is arranged on a ski. The bearing support is supported at the ski so as to be displaceable in the transverse direction of the ski in response to predetermined forces during skiing. In the case of a displacement of the bearing support from a center position it takes up an increasing oblique position with a gradient in the displacement direction to thereby accommodate ski boot movements.

A snowboard has two boot bindings in the form of plate bindings (11, 11'), arranged at a considerable angle to the longitudinal direction of the board. The release mechanisms of the two plate bindings (11, 11') are coupled together in such a way that during release of the one plate binding (11, 11') the release force for the other respective plate binding (11', 11) is at least substantially reduced.

Safety ski binding

A binding coupled ski boot shaft delatching device is described in which the pivotable shaft 12 of the boot can be latched with the lower part 14 of the boot via a latching lever 20. The latching lever 20 is pivotable inwardly into a latching position by a sole clamp 64 against a spring force 34. In this way a falsification of the preset release characteristic of the sole clamp through possible interference of the shaft delatching device with the binding is precluded.

Binding coupled ski boot shaft delatching device

Laterally releasable binding unit for holding the front end of a ski boot (12) including a base part (30) mounted on the ski (22), a release spring arranged longitudinally on the ski and an integral sole clamp (29) having two limbs (14) and a hold down clamp (15). The base part is a carrier spigot vertically tiltably mounted about a transverse axis (36). The sole clamp is rotatably arranged on the upright carrier spigot. A draw rod (38) passes through a slide bore (37') in a ball guide (37) within the carrier spigot and abuts, via a support disc (39) secured to the draw rod at its rear, a substantially flat rear support surface (40) of the carrier spigot. The rear end of the release spring is braced against an abutment (42) fixed to the sole clamp and thus presses the abutment against the front support surface (31) of the carrier spigot. The rear support surface (40') of the carrier spigot and/or the preferably flat counter surface (39') of the support disc above the draw bar, and/or the front surface (31') of the carrier spigot and/or the preferably flat counter surface (42') of the abutment beneath the draw bar (38) are tilted relative to the perpendicular of the surface of the ski in such a way that within a predetermined vertical tilting region (a) of the hold down clamp the hold down force is significantly reduced relative to the normal release hold down force.

Laterally releasable binding unit

A toe unit of a ski safety binding has a housing (15) which is fixedly mountable on a ski, a release spring (14) and sole clamp arms (18) which are pivotable outwardly to the side relative to the housing against spring force and which locate the tip of an inserted ski boot in the sideways direction on the ski (40), but pivot sideways outwardly against the spring force and release the ski boot on the occurrence of sideways forces which lie above a predetermined release value. The space for movement (11) between the housing (15) and the outwardly pivotable sole clamp arms (18) is filled out, at least in the regions which border on the outside atmosphere, and preferably radially outside of the associated pivot axis (13), by an elastic filling piece (12). The elasticity of the filling piece (11) is restricted so that the elastic resetting force at the sole clamp arm (18) generated through compression of the filling piece (12) in the release position of the ski boot only amounts to a fraction of the resetting force generated by the release spring (14).

Toe unit for a safety ski binding

A safety ski binding has a toe unit arranged in front of a front foot plate (21) and a heel unit which exerts a forwardly directed thrust force on the toe unit via the inserted ski boot. The toe unit has a sole clamp (16) which supports the front part of the sole (14) of the ski boot (15) from the front, sideways and from above and is pivotable against a substantially forwardly directed spring force about a respective one of two substantially vertical axes of rotation (17) provided on both sides of the vertical central longitudinal plane (11). An abutment (18) which faces downwardly and forwardly is provided on the sole clamp (16) at the region between the axes of rotation (17) and cooperates with an inclined surface (19) which is fixed relative to the housing and which extends downwardly and rearwardly from the top. The cooperation between abutment (18) and surface (19) is such that when the ski boot (15) is inserted its sole (14) holds the sole clamp (16) against the downwardly directed spring bias at a level at which the abutment (18) is located at at least a small distance from the inclined surface (19). The ski boot (15) is downwardly yieldingly supported on the ski (22) whereby a downwardly directed counterforce to the sole clamp resetting force is generated during a forward fall in dependence on the inclination of the inclined surface (19) and on the resilient bias of the sole clamp (16).

The cross-country ski binding has a plate which is arranged on the upper surface of the ski and is pivotable about a vertical axis located in the ball region of a boot. The plate is held in the central position by means of a latch device which releases to permit rotation of the plate relative to the ski on the occurrence of impermissibly high turning moments relative to the vertical axis and thus relative to the ball region.

Releasable cross-country ski binding

A safety toe unit for a ski binding has two sole retaining jaws (11, 12) which can pivot laterally outwards in opposite directions. A respective projection (13, 14) of a pressure member (19) acts on each of the sole retaining jaws at the front between the pivot axes (15, 16) and shoe retaining rollers (17, 18). The pressure member (19) is arranged for displacement in the longitudinal direction of the ski substantially in front of the sole retaining jaws (11, 12) and is urged in a rearward direction by a compression spring (21) which is braced against a housing (20) which in operation is secured to the ski. The two pivot axes (15, 16) which are spaced by a small transverse distance (A) from the central longitudinal plane (22) are tilted slightly inwardly towards the vertical and central longitudinal axis (22). The pressure member (19) has an extension (24) which extends forwardly inside the coil spring (21) and which is journalled by means of a ball-shaped head (24' ) in an elongate guide sleeve (26).

Safety toe unit for a ski binding

The ski binding part consists essentially of a fulcrum part (1) which is affixed to the ski or displaceable thereon against a biasing spring (5) and on which a latch (2) is fulcrumed on a transverse axis (3) of the ski for the purpose of gripping the heel of the ski boot. On the side of the fulcrum (1) facing away from the boot, a thrust block (10) is displaceably guided on or in the latch and cooperates with a counterthrust member (13) integral with the latch. The longitudinal central axis (M) of the thrust block is disposed at a radial distance (a) below the fulcrum axis (3).

Ski binding part

A laterally releasable toe unit has two laterally pivotable side jaws (11) which are held in a ski boot retaining position by a yoke (26) on which a release spring (30) acts and which can be pivoted laterally while pushing the yoke rearwardly against the spring force to release the ski boot. A toe plate (15) which is movable by a small amount in a vertical direction is arranged behind a laterally fixed toe restrainer (13) and generates, via a force deflection transmission, a longitudinal force which is dependent on the contact force which acts on the toe and which counteracts the spring force via a bar member (12). At least one lever (14) which is acted on by the vertically displaceably or pivotably arranged toe restrainer (13) acts on the same bar member (12) in the same sense with a release force which is dependent on the vertically upwardly directed force acting on the toe restrainer (13).
