Definitions

the present invention relates to a ski boot comprising a first part constituted essentially a sole and an enveloping upper the foot and the malleolar region and a second part consisting of a collar articulated with respect to the rod so as to allow movement of the front collar backwards and vice versa, and means for retaining the collar opposing the tilting of the collar towards the rear but yielding when the effort tending to make tilting the collar exceeds a determined value.
the purpose of such a construction is to protect the knees of the skier, more specifically the cruciate ligament anterior, when excessive forward force is exerted on the tibia relative to the femur. He was observed that ruptures of the anterior cruciate ligament due to excessive effort of this type have increased in a very large extent while other people's injuries types, especially leg fractures and the ankle have decreased considerably due to progress made in security fasteners. A excessive effort on the anterior cruciate ligament produced in particular during a hump passage, whether either by jumping, at the reception, or by descending quickly the bump.
the object of the present invention is to provide means restraint satisfying the same conditions of triggering from a determined effort, but from much simpler construction than the means of restraint known from the prior art.
the shoe according to the invention is characterized in that that the retaining means consist of a part working in compression and yielding by buckling.
the retaining piece may be a salvage piece shaped such as an elastic flexible blade or a part without shape recovery, such as a blade or a bar whose buckling causes it to fold beyond yield strength or a tubular piece sagging by crushing beyond a certain axial compression, such sag can be assimilated to a buckling.
this could be connected to one of the parts of the shoe, preferably the collar, by a clevis hinged on the collar, in such a way that it can occupy either a restraint position or a position separated from the other part of the shoe authorizing the straightening of the collar, i.e. a rest or walking position.
Figure 1 shows the back of a ski boot with, torn away, the retainer according to a first mode of execution.
Figure 2 is a similar view showing a restraint according to a second mode of execution.
Figure 3 is a side view of the device retained according to this second embodiment.
Figure 4 is an axial sectional view of the device shown in Figure 3.
Figure 5 is again a view of the rear of a ski boot fitted with a retainer according to a third embodiment.
Figure 6 shows the retainer of the Figure 5 after subsidence.
Figure 1 partially shows a shoe ski which we recognize the hull 1 comprising a rod 2 and a sole 3 and a lower leg collar 4 articulated on the rod 2 at two opposite points 5 in the malleolar region.
the collar 4 is prevented from tilting backwards by a blade 6 whose ends are retained in housings formed in spans of rod 2 and collar 4.
the blade 6 is for example made of spring steel.
blade 6 When a force is exerted on the collar 4 in the direction of tilting backwards, blade 6 is subjected to axial compression. If this compression exceeds a certain value, blade 6 yields by buckling, as shown in dashed lines 6 '. According to the elasticity of the blade 6, it is capable or not recover its initial shape after flaming. In the case where the blade 6 does not recover its initial shape, the user will replace the blade with a new blade.
the embodiment shown in Figures 2 to 4 differs from the first embodiment in that the blade 6 is mounted in a yoke 7 rotatably mounted on the collar 4 around an axis 8.
the lower end of the blade 6 In use position the lower end of the blade 6 is engaged in a housing 9 of rod 2 and functions as the blade of Figure 1. Thanks to the joint 8, the end of the blade 6 can however be moved away from the rod 2, as shown in dashed lines 6 ". In this position, the blade 6 is ineffective and the collar 4 can straighten up freely.
the retaining device yielding by buckling consists of a tubular piece 10 of truncated or barrel-shaped ovoid shape.
the part 10 can be made of metal or of material synthetic. It will of course be replaced after each crush.
the tubular part could of course be simply cylindrical or of any other shape appropriate.
the resistance of parts yielding by buckling may be adapted to the user morphology.
the solution according to the invention is of course also applicable to a ski boot whose collar is hinged from the back to the back of the shell, for example as described in the requests for Patent EP 0 594 554, EP 0 619 958, EP 0 470 384 or WO 94/21 149.
