Definitions

  • the subject of the present invention is an inner boot for a ski boot with a rigid or semi-rigid shell, in the form of a boot, at least in its front part, having in its front part a narrow deformable zone of less resistance than the rest of the shoe.
  • Modern ski boots with rigid shell with rear entry and internal tightening of the foot or semi-rigid with external tightening of the foot include an internal boot, often called a boot, intended to ensure the comfort of the foot in the boot.
  • This inner shoe is generally made of a flexible material padded internally and often having reinforced parts, in particular around the upper and on the instep, that is to say at the places supporting the pressure of the tightening members.
  • a commonly used inner shoe has a rigid tongue fixed by its lower end near the end of the foot and extending over the instep and on the front part of the upper. The clamping means must not only exert pressure on this tongue, but also on the edges of the notch of the inner shoe covering the tongue.
  • an inner boot-shaped shoe having two substantially parallel slots extending on either side of the instep between the end of the foot and the middle of the front part of the upper so to allow the part of the inner shoe extending over the instep to be raised in order to follow the lifting of this part of the foot during forward bending (DE-A-3429284).
  • These slots can be closed by an extendable part, for example a bellows. Since the inner shoe has a certain rigidity, the effect targeted by this measure is illusory because bending the upper forward has the effect of making tuck the instep area towards the inside of the shoe, since the part covering the instep is fixed by its ends between the upper and the toe.
  • the present invention aims to overcome the aforementioned drawbacks. Its purpose is to produce an inner shoe capable of deforming elastically under the effect of the clamping means, without forming folds or the like, and of uniformly transmitting the pressure of the clamping means, in particular of the distribution plate. on the foot and instep.
  • the inner shoe according to the invention is characterized in that the said deformable narrow zone of least resistance extends across the front part of the upper above and on each side of the instep in the direction of the toe. foot by delimiting a tongue-shaped area extending over the instep.
  • an inner shoe which has a flexible zone in the instep region, capable of adapting perfectly to the instep by regularly transmitting the pressure.
  • clamping means either an internal pressure distribution plate or the pressure of the shell itself under the effect of external clamping means.
  • the location of the deformable narrow zone of least resistance gives the upper of the inner shoe a certain freedom and in particular allows it to flex forward without being retained by the region of the instep. Permanent deformation is eliminated and the flexibility of the inner shoe as a whole is improved due to the decrease in resistance in the instep and ankle region.
  • the inner shoe shown in Figure 1 has the general shape of an open boot at the rear.
  • the rear part is generally provided with a tongue, not shown.
  • This inner shoe is made by means of a flexible envelope provided with inner padding. It has an external reinforcement 1 of synthetic material around the rod.
  • the inner shoe On its front part, the inner shoe has a deformable narrow zone of least resistance 2 extending across the front part of the upper 3 and on each side of the instep 4, in the direction of the toe 5, so that it delimits a tongue-shaped zone 4 extending rearward the region of the foot 6.
  • the deformable zone 2 is preferably in the form of a bellows, as shown in FIG. 2.
  • This bellows may have come in one piece with the plastic casing 7 constituting the outer and inner walls of the boot and containing a synthetic foam. 8.
  • the part 2, designated 2 ′ in this FIG. 3 can simply be constituted by a flexible thinning of the wall of the boot.
  • Zone 4 having a shape adapted to the instep, it transmits the clamping pressure in a well distributed manner. There is therefore no localized compression zone created.
  • the deformable zone 2 improves the flexibility of the inner shoe as a whole. In particular, a bending movement of the rod 3 forwards or backwards is facilitated.
  • Figure 4 illustrates the bending of the rod 3 forward. The position of the rod 3 ′ bent forward is shown in dashed lines. It must be imagined that the region 4 is maintained between the foot and the shell, respectively the clamping means. Without the deformable zone 2, the rod 3 could hardly bend.
  • Region 4 could be further strengthened without further ado. This reinforcement could even make it possible to dispense with an auxiliary pressure distribution part.
