Abstract
A structure associated with a motorcycle boot which is designed to restrict, in the event of accidental falls followed by contact at high speed with the ground, the movements of a leg-piece of the boot with respect to the axis of a heel-piece, comprises a first hinge, which is angularly movable in a substantially unlimited manner and axially movable between two stopping means, and second hinge which is movable only angularly in a restricted manner. Alternatively, the first and second hinges can be formed of elastomeric materials.
Claims5
A structure associated with a motorcycle boot having a heel region and a malleolus region, comprising:
- at least one leg-piece hingedly connected with at least one heel-piece so that the at least one leg-piece is axially and angularly movable relative to the at least one-heel piece,
- a first hinge provided between the at least one leg-piece and the at least one heel-piece and positioned close to the heel region, wherein the first hinge limits axial movement but does not restrict angular movement of the at least one leg-piece relative to the at least one heel-piece, and
- a second hinge provided between the at least one leg-piece and the at least one heel-piece and positioned close to the malleolus region, wherein the second hinge restricts angular movement of the at least one leg-piece relative to the at least one heel-piece,
- wherein the second hinge further comprises at least one arch-shaped tongue centred on the first hinge that projects from the at least one leg-piece, said at least one arch-shaped tongue being slidable under a raised bridge protruding from the at least one heel-piece, and
- wherein the at least one arched-shaped tongue is provided with at least first upper stopping means, which restrict angular movement of the at least one leg-piece during closing of the motorcycle boot, and second lower stopping means which restrict such movement during opening of the motorcycle boot.

- at least one leg-piece hingedly connected with at least one heel-piece so that the at least one leg-piece is axially and angularly movable relative to the at least one-heel piece,
- a first hinge provided between the at least one leg-piece and the at least one heel-piece and positioned close to the heel region, wherein the first hinge limits axial movement but does not restrict angular movement of the at least one leg-piece relative to the at least one heel-piece, and
- a second hinge provided between the at least one leg-piece and the at least one heel-piece and positioned close to the malleolus region, wherein the second hinge restricts angular movement of the at least one leg-piece relative to the at least one heel-piece,
- wherein the second hinge further comprises at least one arch-shaped tongue centred on the first hinge that projects from the at least one leg-piece and is curved inward in a spherical manner and is slidable into a pocket having a shape matching that of the at least one arch-shaped tongue, said pocket provided in the at least one heel-piece, and
- wherein the at least one arch-shaped tongue is provided with stopping means for restricting the angular movement during closing and with a dampening system for dampening the angular movement during opening.
