Abstract: Step-in snowboard binding designed to hold a boot by its sides. The binding comprises at least one jaw secured to a driving arm intended to be driven by the boot. The jaw has a cam-shaped part collaborating with a locking element which can move in a guide in such a way that the jaw is locked for various positions of the jaw. The jaw 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: Snowboard binding comprising a baseplate (1) on which is mounted a bow (7) that is adjustable in terms of position by means of two pairs of nuts and screws and a highback (8) mounted on the bow so chat it is orientable. Each of the screws (25) used to mount the highback (8) on the bow (7) and one of the screws (22, 24) of the pair of screws used to fix the bow to the baseplate arc coaxial and share a common nut (17, 19). This construction has the effect of simplifying the nut-and-screw fittings and of increasing the range of orientation of the highback.

Abstract: The boot/binding assembly for a snowboard with an automatic binding has a base (12) having a device (14) for holding the boot via its sides and complementary forms guiding and positioning the boot in the binding. The guiding and positioning forms (16) located on the binding extend above the holding device (14) for holding the boot so as to prevent the actuation of the holding device until the boot is fully positioned relative to the binding.

Abstract: The connecting device consists of a circular disk (7) fixed to the snowboard and fitting into a circular ring (8) holding the binding (1) on the board. The interior circular contour (11) of the ring into which the disk fits is eccentric relative to the exterior contour of the ring. The mechanical continuity provided by the ring guarantees that the binding will be held in position without high pressure needing to be exerted on this ring.

Abstract: Automatic snowboard binding holding the boot via its sides and having an automatic locking mechanism (11, 14), retention mechanism (6), and a boot-release lever (16) whose operation results in unlocking of the retention mechanism. The boot-release lever is kinematically independent of the locking mechanism (11, 14) in such a manner that it remains stationary when the boot is clipped into the binding.

Abstract: Step-in snowboard binding designed to hold a boot by its sides. The binding comprises at least one jaw (2) secured to a driving arm (9) intended to be driven by the boot. 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 shell having on its external surface, also called sole, a circular opening comprising a rim with teeth for receiving said device for fixing the shell to the surf board. Said device consists of a first circular part (1) fixed on the surf board defining at its lower portion housings (15) with the surf board surface and retaining at its periphery a second circular part (2) fixed in rotation with said first part leaving it free to move in the direction perpendicular to the surf board over a predetermined distance. The second part has at its lower surface teeth (21) corresponding to said shell teeth. The device further comprises a third circular part (3) arranged beneath the first part in said housings, that is between the surf board and said first part, maintained fixed by the latter in the perpendicular direction but in free rotation over a predetermined angle.

Abstract: A boot/binding system for a snowboard wherein the boot includes a sole and transverse bar having two ends. A binding includes a base defining a horizontal plane and a median plane. The binding is selectively fixed to the board in a plurality of positions and is pivotal about an axis which is perpendicular to the horizontal plane and intersects the horizontal plane at point O. The binding includes two vertical plates arranged substantially parallel to the median plane, each of the vertical plates including a vertical groove into which one end of the transverse bar of the boot is insertable. The ends of said bar are held inside each groove by a pivoting cam elastically held in position. A first region of contact of the bar end is in contact with a front wall of the groove and the first region of contact is contained in a normal plane formed by the front wall of the groove.
