Abstract: A back protection device for the practice of sporting activities includes a plate covering at least partially the surface of the back and in the thickness of which recesses are made intended to ensure the flexibility of the plate. The plate comprises a longitudinal ridge, the axis of which is intended to extend along the spine by delimiting, on either side, two right and left parts, each composed of an upper zone and a lower zone. The four zones are movable relative to each other, each being provided with recesses in the form of slots opening onto at least one face of the plate and being oriented with an inclination angle that is variable relative to the axis of the longitudinal ridge, so as to dissociate the flexibility of said zones.

Abstract: Snowboard binding has a base plate (1) having an arch (4), a rear support piece (24) which can be displaced on the base plate, a foot strap (13), optionally an instep strap (5), and a linking device for kinematic linking between the foot strap and the rear support piece. The kinematic linking device has linking pieces (14, 15, 25, 26) connecting the support piece (24) and the foot strap (13) and passing on each side of the central zone of the base plate. This binding may be adjusted rapidly, symmetrically or non-symmetrically, without the necessity of removing and replacing screws.

Abstract: A clamping device for two telescopic tubes (1, 2) comprises a ring (7) which is longitudinally split and thus defines a longitudinal spacing (8) located in a plane intersecting the ring (7) longitudinally, said ring (7) being extended towards the outside by two wings (9, 11) facing each other on either side of the longitudinal spacing (8), at least one rod forming an axis (A) arranged transversely in relation to the plane and passing through the two wings (9, 11), and an arm (12) which is fixed and pivots in relation to the rod forming an axis (A), so as to make possible clamping of the ring (7) by reduction of the longitudinal spacing (8), the two wings (9, 11) being brought towards one another. The arm (12) is divided into two branches (13, 14) each having a free end through which the rod forming an axis (A) passes, the two branches (13, 14) and also the free ends coming to lie on either side of the two wings (9, 11) of the ring (7) in order to enclose said two wings (9, 11).

Abstract: Holding device comprising a body (1) mounted so as to slide in a rail (4) on which it is maintained in position by means of a lock (9) that is articulated to the body (1) and is provided with an unlocking lever (20). This unlocking lever is provided with two lateral flanges (21, 22) extending toward the rail, on each side of the central region of the latter. The flanges (21, 22) are preferably divergent and their rear edge (23) is inclined. This form of unlocking lever secures the lock against accidental unlocking in the event of impact.
