DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/FR95/01125 filed on Aug. 25, 1995.
The present invention relates to an inner for a sports boot, in particular ski boot.
Some high boots, in particular sports boots and especially ski boots, contain an inner which is intended to protect the foot against friction with the rigid parts of the boot.
In a number of sports, it is actually necessary for the foot to be wedged securely in the boot, in order to allow accurate control of objects which are fixed to the latter, in particular a ski. The foot is therefore exposed to repeated friction, and the inner protects it accordingly.
However, the boot is only very approximately adapted to the specific morphology of the foot and the lower leg, because it must be suitable for a large number of users.
The same is true for the inner, which corresponds only very approximately to a standard foot shape.
The boot is adjusted to the user's foot using loops, straps or laces, the purpose of which is to tighten it to a greater or lesser extent, while comprising the boot around the foot.
This tightening has the drawback that it cannot be uniform and that it creates excess pressures at some sensitive points on the foot.
In order to alleviate these pressures, it is well known to provide a padded boot, comprising a tongue which covers the instep and the front part of the lower leg. This tongue makes it possible to close the opening which allows the foot to be inserted into the boot, to distribute the tightening force of the boot over the aforementioned regions of the foot and the lower leg, and to protect the sensitive parts of the foot.
However, a tongue of this type has the significant drawback that it shifts under the effect of the repeated movements of the foot relative to the boot, until it becomes displaced fully to one or other of the sides of the inner. It then no longer fulfills its function of protecting and holding the foot, so that the inner becomes particularly uncomfortable for the user.
It is also known, for example from the U.S. Patents U.S. Pat. No. 4,182,056 or U.S. Pat. No. 3,786,580, as well as from international application WO-94/09663, to provide an inner which does not comprise a tongue, but comprises flaps which overlap level with the instep and the front of the lower part of the leg.
Although they are generally satisfactory in practice, these inners have the drawback that they do not ensure perfect holding and comfort for the foot, in particular because they are not perfectly matched to the very particular asymmetric anatomy of this part of the body.
In addition, it is well known to shape an inner blank between the foot and the rigid shell of the boot, so as to obtain a distribution of the material of the inner in the space existing between the foot and the shell, by plastic flow or differential compression of this material. This shaping makes it possible to obtain an inner which fits and holds the foot.
The capacities of the material of the blank for plastic flow and differential compression remain, in spite of everything, relatively limited, and do not make it possible to obtain holding and comfort for the foot in all the regions of the latter. This is the case, in particular, when the blank employed has a rough shape, that is to say has the appearance of a large stocking which is open longitudinally level with those of its parts which correspond to the instep and the lower leg. A blank of this type does not correspond very precisely to the shape of the foot and the lower leg, and the limited capacities for plastic flow and compression of the material do not make it possible to compensate for this inaccuracy, in order to obtain the desired holding and comfort.
The present invention aims to overcome these various drawbacks.
Its object is to provide an inner which, remaining standard, is more padded at some points than at others so as to correspond optimally to the anatomical shape of the foot.
The inner to which it relates is of the type comprising a part intended to hold the foot, and a substantially tubular part intended
