The boot sole becomes more restricted in the longitudinal and transverse directions, the further the boot is introduced into the binding, and a snowboard and a boot combination further having interengaging boot-retaining members on the binding and locking parts on the boot sole.

Abstract: That end of a ski boot which is retained by the boot-retaining unit is retained such that it can be disengaged in the sideways direction and vertical direction. Upon sideways movement of the ski boot within a range of elasticity of the boot-retaining unit, the ski boot is rendered capable of moving increasingly in the upward direction, strong forces in the upward direction producing a force component which additionally forces the boot-retaining unit in the sideways direction.

Abstract: A binding (1) retains a ski boot (5) on a ski (3) in a releasable manner. A jaw (4, 4a, 4b) is disposed symmetrically with respect to a longitudinal-vertical plane of symmetry (P). The jaw (4, 4a, 4b) is resiliently biases against a housing by a compression spring (12) acting on a pulling member (9) which is pivotally attached to the jaw by a pin (10). The jaw (4) includes rollers (14a, 14b, 15a, 15b) which help to retain the toe of the ski boot (5) on the ski (3). Two pivot axes (XX', YY') are defined by projections (7a, 7b) that are received in grooves (8a, 8b). The projections (7a, 7b) are defined by the housing (2) and the grooves (8a, 8b) are on a mating surface of the jaw (4, 4a, 4b), or vice versa. The pivot axes (XX', YY') are not symmetric with respect to the plane of symmetry (P). One of the axes is displaced a further distance (d) from the symmetry plane (P) than the other such that they operate on the compression springs with different effective lever arms (D1, D2).

The front end of this plate bears elastically (24, 25) against the body (3) of the binding, so as to follow movement of the rod when the boot is engaged, in such a way that the display of the preload of the spring is not modified by the engagement of the boot.

Abstract: A toe piece for a ski safety binding includes a jaw having two lateral arms. The lateral arms pivot about a pin. The return and holding forces during the elastic travel are proportional to the triggering threshold. The useful elastic travel is independent of the triggering threshold. A lateral arm of a jaw exerts a moment on a lever which pivots. The lever is connected at one end to a spring. The triggering threshold is adjusted by altering the ratio of the distances between, on the one hand, the pivot of the lever and the point of contact between the spring and the lever and, on the other hand, the pivot of the lever and the point of contact between the jaw and the lever. The jaw acts on the lever through a movable part which is moved to adjust the triggering threshold.

Abstract: A binding element adapted to retain the end of a boot. It includes a body that bears on a jaw. The jaw is vertically movable, and its movement is transmitted to the return spring of the jaw, which constitutes a compensation for a backward fall. The sole of the boot is pinched between a support plate and sole-tightener of the jaw. The support plate is movably mounted about a horizontal and longitudinal axis so that a twisting of the boot causes an elevation of the jaw and thus, activates the compensation mechanism.

These surfaces are preferably in the shape of a "W" and an inverted "W" in transverse cross-section, whose apices form an area of contact when the plate is aligned on the ski. No direct or indirect linkage is provided between the plate and the elements of the binding during release, however, and the plate is recentered after release in response to the return of the wings to their retention position.
