Abstract: A boot having a structure for the treatment of the micro-vibrations that can occur between the bottom assembly and the upper of the latter by resonance effect on impact with the ground. A thin elastic membrane with a Shore A hardness of about 20-30 is positioned between the core layer of the bottom assembly and the upper to serve as a dynamic screen with respect to the micro-vibrations. The invention is particularly adapted to the design of sports boot, such as walking shoes and/or running shoes.

Abstract: A sport boot that can be converted to adapt to a variety of sports, especially gliding sports. The sole of the boot is constituted of an irremovable base affixed to the shell, and on which front and rear vertical retention zones are obtained, on the one hand, and of front and rear sole portions that are distinct, interchangeable and complementary to the sole base to which they adapt to constitute the tip and the heel, respectively, and being selected by the user among at least two sets of front and rear sole portions whose profiles and dimensional characteristics are capable of allowing, relative to the front and rear zones for the axial retention of the fixed base and complementarily with the latter, to recontitute and adapt a sole from the same boot, conforming to one binding standard or another.

Abstract: A sports boot with a rigid shell, having an upper that can be opened along the front and being connected via lateral journals to a shell base and that is blocked in its rearward pivoting by its lower edge that becomes supported along an edge of the shell base. A scalloping in the shape of an inverted "U" is provided in the lower edge of the upper in the extension of the dorsal zone thereof in order to weaken it at this spot and to reduce the bearing length of its lower edge along the edge of the shell base. At least one removable cam is capable of being actuated within the scalloping in order to stop any rearward elastic deformation of the upper.

Abstract: An alpine ski boot having a shell base on which an upper is journalled. The upper includes a rear spoiler that is pivotally mounted about a transverse axis located at the rear portion of the shell base. The boot also includes a stirrup that is journalled on the shell base in the area of the ankle. The stirrup extends to the area of the heel, where it is connected to the rear spoiler, forming a connection with the rear spoiler, with respect to the shell base.

Abstract: Device for opening and closing a rear-entry ski boot, by simultaneous rotation of front and rear portions of the upper without raising the front portion. The rear portion rotates on the shell base about a hinge pin, and the front portion about a pivot axis at the front end of the shell base. The front and rear portions are joined to each other by a pin-and-slot connection located in overlapping extensions of these elements.

Abstract: A ski boot, preferably of the rear-entry type, including an upper portion selectively movable between an open position and a closed position. A control element, such as a cable, is included which can be associated with an arrangement for maintaining the foot or lower leg relatively fixed within the boot, or an arrangement for modifying the flexion of the boot. An arrangement is provided for tensioning the control element, in response to movement of an upper portion of the boot toward a closed position, which is mechanically independent of an arrangement for maintaining the tension in the control element.

Abstract: An alpine ski boot having includes a shell base and an upper journalled at least in one part on the shell base. Between the upper and the shell base a support is provided, itself being journalled on the shell base about a generally horizontal and transverse axis. The upper is journalled on the support about an axis separate from the aforementioned axis. Further, the boot includes a latching device to immobilize the support and, consequently, the journal axis of the upper on the support in a first upper position for skiing and to free the support, during removal, so as to permit a pivoting of the support with respect to the base, about its axis, towards a second lower position, leading to a displacement towards the rear, and possibly downwardly, of the journal axis of the upper on the support.

Abstract: A rear-entry ski boot having a rigid shell and an upper constituted by a front cuff and a rear spoiler, and system for fastening and adjusting the boot on the lower leg of the skier. The upper includes a central sleeve journalled on the shell base and having a front opening and a rear opening defined by the two lateral walls of the upper part; a rear spoiler journalled on the sleeve and adapted to close the rear opening of the sleeve; and a front cuff journalled on a lower front zone of the sleeve and adapted to close the front opening of the sleeve. With the construction of the ski boot, the upper is made adjustable to more effectively support the skier's lower leg. Various latching mechanisms and locking mechanisms are also provided.

Abstract: The shoe incorporates a shaft (3) jointed (5) to a shell (1) along a transverse axis (5'), connecting two joint pieces (5) on each side of the shoe and connected to one another by a stirrup (6). The joint pieces (5), stationary in relation to the shaft (3), may be moved (52) in an approximately vertical direction in relation to the shell (1) and may be locked into position. The stirrup (6) is located in the upper part of the shell (1) and surrounds the top of the wearer's instep, thereby distributing the bearing stresses exerted by the shaft (3) on the shell (1) in the area of the instep.

Abstract: Ski boot comprised of a rigid shell at least partially surmounted by an upper (4) and at least one padding element (9) inside the boot intended to block the skier's foot. The boot comprises a blocking device (12) having a block (16, 16') extending from each side of the zone of the Achilles tendon into the hollow of the malleoli located above the protuberance of the calcaneum, and the block is attached to a block holder (14) provided with a height adjustment device (17, 17'), arranged along the median vertical axis of the back of the upper.

Abstract: A safety ski binding comprises a stirrup mounted to a ski or a sole-plate. Articulated to the stirrup is a toggle mechanism including a spring biased holding member arranged to engage the edge of the sole of a ski boot. The holding member is displaceable in a direction toward the toggle to release the boot upon application of a predetermined minimum separating stress.

Abstract: A support plate of a ski binding has a rigid boot sole hold-down loop slidably mounted on lateral guide profiles at an end of the support. The rigid loop has a central part which fits over the sole and bent, integral end parts terminating with complementary profiles fitting on the guide profiles of the support. Positioning notches on the support cooperate with notches of an element slidably mounted on the arms of the loop which can be clamped on the support to lock the loop in position. Alternatively, the notches are formed in the complementary guide profiles, and are clamped by a similar element slidably mounted on the loop arms.

Abstract: A safety ski binding comprises a sole grip pivoted on an end of a sole-supporting plate elastically connected to the ski by a flexible cable tensioned by a spring winder incorporated in the plate. A device for automatically opening the sole grip, after removal of the sole grip from the ski by withdrawal of the cable but before the cable is fully withdrawn, comprises a projection on the winder which actuates a lever to pull or push a transmission member which either disengages a bolt retaining the heel grip, or directly tips the grip open against the action of a biasing spring.
