The jaw has a cam-shaped part (9) collaborating with a locking element (12) which can move in a guide (13) in such a way that the jaw is locked for various positions of the jaw. The jaw (2) is equipped with a return spring which tends to keep it in the open position, and the jaw and the locking element cooperate to keep the locking element away from its locking position when the jaw is raised. In this way, the jaw cannot be closed inadvertently and the locking element does not hamper the closure movement.

Abstract: A safety binding for a ski boot having a sole clamp divided into two sole clamps (3, 4) each mounted pivoting about a particular more or less vertical axis. The sole clamps (3, 4) form two levers of a first type with two diverging arms designed to retain the boot laterally and two substantially converging arms perpendicular to the longitudinal axis. Each sole clamp is provided with a descending arm (9, 10) which bears against two adjacent points on the end of a piston (13). The piston is axially mounted in the body (1) of the binding and extends beneath the boot. A spring is biased against the piston. The descending arms (9, 10) simultaneously control the elastic tilting of the sole clamp in a vertical plane.

Abstract: A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is provided with stiffness adjustability for accommodating the rider's particular riding preferences. Adjusting the highback stiffness allows the rider to selectively increase or decrease force transmission and board response based on individual riding preferences and/or riding conditions. Adjusting highback stiffness may also allow a rider to reduce pressure points between the highback and the leg, particularly the rider's calf muscle, for increased comfort while maintaining heelside support for board control. The highback includes a back member that may employ one or more sections that can be selectively adjusted to achieve a desired highback stiffness for board response and comfort. The degree of stiffness may be established by adjusting the flexibility of the highback at preselected locations of the back member.

A spring piston locks the driving element directly or indirectly in the closed position. This locking effect is realized in such a way that the closing force of the binding does not depend on the force of the spring of the spring piston.

Abstract: A tightening device for the heel portion of a safety ski binding comprises a ski boot holding member which includes a sole holder and a closing pedal positioned between arms extending from upright shoulders connected to a turntable attachable to a ski. A support member with one of its ends pivotally attached to the bottom of the holding member has a hook on its free end, and when a ski on which the binding is mounted is to be transported, the support member can be pivoted from a holding member supporting position in which its free end rests on an upper surface associated with the ski, to a position in which the hook engages a projecting surface forming part of the turntable, or of a bearing surface associated therewith. The binding components are thus locked in a tightened position, eliminating movement therebetween.

Abstract: The anti-friction plate is guided by vertical and longitudinal guidance apparatus allowing for a free lateral movement. The free lateral extent of plate 1 is limited by the play of the lateral ramps of an opening 22 which is laterally movable with the anti-friction plate 1 and in which a spur 26 affixed to jaw 6 penetrates. Spur 26 assures the recentering of plate 1 when the jaw 6 returns to the centered position, and frees the plate when the jaw is pivoted.

Abstract: The invention concerns a ski safety binding with a sole plate pivoting about a rising pin. The sole plate cannot however be lifted off the ski. The sole plate includes at its rear a heel holder and at its front a toe piece. The sole holder is pivotable about a cross rod at the front. The toe piece includes a control member associated with a control cam of a guide plate. When a pre-determined pivot angle of the sole holder relative to the longitudinal ski axis is reached, the control cam allows the sole holder to pivot to allow the release of the ski boot. In the present invention the front of the sole plate is designed to be a bearing which supports at least one cross bolt which supports the sole holder, the control member and a ratchet lever. Further, at the front of the bearing is an attachment which enters a guide groove located in the guide plate and is moveable in longitudinally displaceable manner on a base plate.

Abstract: A binding for retaining a boot on a ski. The binding is provided with a jaw for retaining one end of a boot against the ski, and a support on which the jaw is mounted. The support itself is connected to two arms mounted on the ski. These two arms are separated by a distance less than the width of a sole of the boot which the binding retains on the ski.

Abstract: A ski binding adapted to be displaced between a boot retaining and boot releasing position. The binding includes a jaw and two lateral arms pivotally connected at one end to the ski around a first transverse axis and pivotally connected at their other end to the jaw around a second transverse axis passing through a journal. Also provided is an elastic element for biasing the jaw against pivoting around the second transverse axis, and a retractable support. The support supports the jaw, the arms and the journal when the support is in its active position. The support is also retractable to an inactive position in which the jaw, the arms, and the journal are unsupported by the support. When the support is retracted into this inactive position the jaw, the arms, and the journal can be displaced around the first transverse axis to release the boot from the binding without substantial pivoting around the first transverse axis, and therefore without pivoting against the bias of the elastic element.

A housing is provided and includes a sole holder pivotally supported for movement about a transversely extending axle against the force of at least one spring and which carries a roller loaded by a further spring on a control lever. The roller is associated with a curved surface mounted on a ski-fixed member and controlling the lateral pivoting of the sole plate, whereby one of the springs is nested coaxially into the other in the housing and the housing is secured on the sole plate extension members.

Abstract: A safety ski binding provided with a sole plate supported pivotally on a ski-fixed pivot, however, is secured against lifting off from the ski carries at its rear end a heel holder and at its front end a front jaw. The front jaw is pivotal about a transverse axle and carries a control element extending in the longitudinal direction of the ski in the skiing position. On the front end of the control element is supported rotatably a roller, with which is associated a cam secured on the ski, which cam, upon reaching a predetermined angle of traverse of the sole plate relative to the longitudinal direction of the ski, permits a pivoting of the front jaw in the sense of a release of the ski shoe. In order to permit in such a ski binding a storing of the cam protected against dirt, the invention provides that the cam (2f) for the roller (15) of the control element (14) is stored in a housing (2,7) which is open only toward the tail end of the ski and serves to support the front jaw (10,17).

Abstract: A cross-country ski binding for cross-country ski shoes which have, at their front sole end, engagement elements which correspond with and engage into engagement elements of the ski binding, to provide a pivot connection. The ski binding has a U-shaped clip or stirrup member for securing the front sole end against lifting off the ski binding engagement elements, the legs of which clip are mounted pivotably about a transverse axis by their free ends to side jaws of the ski binding, which are fixed to the ski, and which clip is loaded by a spring in the direction toward a position engaging over the front sole end by its web portion. Further, the ski binding has a spring-loaded locking lever, which can engage behind a catch projection of the ski binding by means of a latch and can thereby hold the U-shaped clip in an open position.
