Abstract: An in-line skate frame that has a main body with a transverse base equipped with at least one support surface at the toe of the boot, one support surface at the heel of the boot, two projecting lateral portions that extend the transverse base downward, and two flange portions which are adapted to receive a series of wheels. The flange portions are independent attached elements connected to the projecting lateral portions of the main body. The two projecting lateral portions each have at least one fitting formed by a groove serving as the housing of at least one zone of each flange portion, each groove being bordered by an outer wall of the projecting lateral portion and by a bracing portion common to both grooves, laterally spaced apart from one another. A frame of this type has improved properties of strength and flexural and torsional rigidity, while being simple and economical to assemble.

Abstract: A sport boot with an upper and a shell base journalled on axles has at least one reinforcement element of the shell base. The reinforcement element has an abutment zone capable of cooperating with a retractable support element which, fixedly positioned on the upper, makes it possible to block the upper in its pivoting about axles as early as its initial position or after a certain bending, and to thus transmit the forces of the upper to the shell base.

Abstract: An alpine ski boot having a shell base provided with an external sole topped by an upper that is provided with a central and/or anterior opening for the passage of the skier's foot and which forms, at its upper portion, a collar adapted to encircle the lower part of the leg with at least one tensioning member positioned on transverse flaps. The boot is composed of two main parts that are constituted, on the one hand, by the shell base having a longitudinal opening at its upper portion and made of a relatively rigid material and, on the other hand, by a single opening-closing element attached and fixed on a periphery of the upper longitudinal opening of the shell base, this element itself having, all in one piece, a first substantially vertical portion forming the upper, and a substantially horizontal second portion obtained in the extension of the first and forming an upper cuff for holding the foot, the assembly thus formed being obtained in a relatively less rigid material than that of the shell base.

Abstract: A ski boot comprising an upper (44) jointed (5) to the shell base (6) and a stiffness-adjustment device (12) which incorporates two support elements (13, 14) connected by a connection member (15) and is associated with a rear support stop (10) incorporated into the upper (44). One (13) of the support elements (13, 14) of the stiffness-adjustment device (12) is rigidly linked to the rear support stop (10) on a common axis of rotation (16) in order to form a rotating assembly (10-13), and the element (13) and the stop (10) are both moved out of center on the same side and by the same value in relation to the axis of rotation (16). The invention makes it possible to adjust the angle of forward motion of the upper (44) without affecting the forward motion-adjustment device (12) by simple rotation of the rotating assembly (10-13).

Abstract: Front- and/or central-entry ski boot equipped with a comfort sock (3) and having an upper/collar (4) made adjustable over the lower leg by transverse flaps (1) and closure systems (13). The upper (4, 44) is jointed around an axis (5) on the shell base (6) in the area of the malleoli and can pivot only in the forward direction, since a permanent stop-motion arrangement (14) on the shell base (6) prevents it from pivoting rearwardly.

Abstract: Sport boot incorporating a shell base (1) surmounted by an upper (2) adjustable on the wearer's lower leg and comprising an immobilization device (4) functioning in and in relation to the upper (2). The immobilization device (4) comprises a rotating shim (6) on a pin (7), this shim extending on the inner wall (16) of the upper (2) and in proximity to the upper edge (12) thereof. The shim (6) is provided with a projection (8) which, depending on the angular position thereof, retracts into a recess (14) in the upper (2) or protrudes onto the wall (16) of the latter. The immobilization device (4) makes possible the effective adaptation of the upper (2) to the morphology of the wearer's lower leg.

Abstract: A ski boot structure in which the front cuff of the upper is intended to constitute the reference element ensuring all the functions related to the flexion control of said upper in cooperation with rigid extensions of the shell base and the closure device of the upper on the lower part of the skier's leg in skiing position. On the one hand, the front cuff includes abutments located opposite the abutments obtained on the extensions in the upper zone of the upper, and on the other hand, in the lower portion where it is extended by fastening hooks, an elastic element mounted in tension state to act in the front-to-rear direction. The closure device mutually connects the front cuff and rear spoiler on the inserted extensions while thus allowing the frontward flexion of the front cuff, and therefore of the upper, against the resistance of the elastic element without biasing said extensions and while rearwardly blocking said upper by means of the abutments of the cuff against those of the extensions.

Abstract: Comfort sock designed to be arranged inside the shell of a sports boot, such as a ski boot. The sock (1) incorporates a one-piece structure comprising a foot covering (6) with a vamp (7) and an upper (8), a reinforcement (13), and at least one comfort support liner (11) independent of the covering (6) and connected to the reinforcement (13) of pivoting-sliding connections (16). This support liner (11) is arranged opposite an elastic area (9) of the foot covering (6), against which it comes into close contact at the time of closure of the shell of the boot in which the sock (1) is positioned.

Abstract: A removable protective cover for use with a liner of a sports shoe or boot, and a liner adapted for use with the cover. The cover includes a sock portion and a fold-back portion, the fold-back portion being movable over the front upper portion of the upper of the liner to provide a linkage between the protective cover and the liner. Corresponding, non-permanent attachment zones may be provided on the protective cover and the liner. The sock portion may include an extension, preferably composed of an elastic waterproof material, which may partially or completely cover the exterior surface of the liner.
