Definitions

  • the present invention relates to an alpine ski boot, comprising a shell bottom on the rear part of which is pivotally mounted, around a horizontal and transverse axis, the rear part of the upper of the boot.

  • Certain known boots of this type are moreover provided with locking devices which make it possible to block the upper relative to the bottom of the shell in a given position such that the lower leg of the skier, when he is putting on his boot, is inclined towards the forward with respect to the horizontal plane. In this forward inclined position, which is suitable for skiing, the rod makes, with the horizontal plane, an angle called "initial advance".

They comprise two parts fixed respectively to the upper of the shoe and to the bottom of the shell, these two parts being secured to each other in a first position, for blocking the upper in the "forward” position by relative to the bottom of the shell, and in a second position for unlocking the rod relative to the bottom of the shell, which then facilitates walking with the ski boot when the rod is held tight on the lower leg.
  • Document EP-A-242 526 describes a device for connecting a rod with respect to a shoe shell.
  • This device is a two-position toggle mechanism, the first known as the “closed position” where the rod is held with a certain elastic bending towards the front to allow skiing, the second known as the “open position” where the articulation of the rod on the shell is made over a sufficiently large range to allow walking.
  • Document EP-A-232 218 describes a shoe which comprises in particular a shell, a two-part upper, a damping device between the two parts of the upper and a mechanism for acting on the relative position of the shell and the stem.
  • a first position allows skiing to be practiced by holding the rear part of the rod towards the front, which is combined with elastic bending of the front part of the rod thanks to the damping device.
  • a second position allows walking when the abutment is removed.
  • the present invention aims to remedy this drawback by very simple means making it possible, during skiing, to stiffen the whole of the rod at the same time as to easily control the angle of advance of it.

  • the stiffening element 7 is an integral part of a independent rear stiffening cover 71 which is articulated, at its lower end, on the shell bottom 1, around the horizontal and transverse axis 8.
  • the rear stiffening cover 71 comprises a rear wall 71a which may be planar or, as it is represented in FIG. 38, curve with concavity turned towards the rear.
  • Tie rods 72 extend between the rear wall 71 a of the rear stiffening cover 71 and the stiffening element 7.
  • This rear wall 71a is extended, towards the front, on each side, by two upper lateral parts 71b and lower 71c, the front edges 71d of which have a shape complementary to that of the rear edges of the two lateral parts 2e of the collar 2.
  • the front edges 71d of the rear stiffening cover 71 are in contact, in the closed position of the boot, with the rear edges of the two lateral sides 2e of the collar 2 whose profile they match.
  • Each upper side part 71b may extend further forward than the lower side part 71c as shown in FIG. 38.
  • the reverse arrangement could also be adopted and one could even provide upper parts 71b and lower 71c aligned vertically, that is to say with their front edges located in the extension of one another.
  • the shoe could include the upper 71b and lower 71c parts of the rear stiffening cover 71 only on its internal face, that is to say that facing the other shoe.
  • the cable 6 of the lower leg clamping device passes through the upper opening defined between the upper tie 72 and the end part upper of the stiffening element 7. It also passes through an eyelet 73 formed in each upper lateral part 71b of the rear stiffening cover 71.
