Definitions

  • the present invention relates to an inner liner for a ski boot, said inner liner being provided with an improved tightening system.
  • the present invention further relates to a ski boot comprising an outer shell and said inner liner.
  • Ski boots comprising an outer member, or outer shell, made of a substantially rigid material, and an inner member, or inner liner, housed in said outer member or shell and made of a substantially soft material, are known in the state of the art.
  • the user's comfort is largely influenced by the inner liner made of a soft material.
  • Said inner liner must adhere as closely as possible to the user's foot, on one part, and to the inner surface of the outer shell, on the other part.
  • the presence of gaps between the inner liner and the user's foot, or between the inner liner and the outer shell is also detrimental to the sports performance of the user, because it reduces the user's sensitivity.
  • the movements In the case of ski boots, for example, in order to properly handle the ski, the movements must be rigidly transferred from the user's foot to the ski boot, and from the latter to the ski.
  • the kinematic chain of the motion transmission from the user's foot to the ski loses precision, and this loss of precision negatively affects a proper and accurate handling of the ski.
  • thermoformable materials for the making of such inner liners or parts thereof: the use of thermoformable materials allows to form the inner liner to the shape of the user's foot, while the user is wearing the inner liner, so as to ensure accurate customization, at least at those areas that are most critical for comfort (for example, the malleolar area).
  • the inner liner can be customized so as to faithfully follow - under in-use conditions - the exact morphology of the user's foot, however, it must however be considered that it will be necessary to provide for the possibility of enlarging, to some extent, the inner liner to allow introduction/extraction of the user's foot into/from the inner liner.
  • inner liners can be provided with a longitudinal front opening, which defines two facing flaps of upper which can be spread apart for allowing introduction/extraction of the foot.
  • Said central opening is usually covered by a tongue and is provided with a tightening system allowing tightening of the inner liner onto the user's foot, once the foot has been introduced into the inner liner, until complete adherence of the inner liner to the shape of the foot.
  • Said tightening system is arranged essentially at the longitudinal front opening and bridging said opening, and can be made as a lacing system, in the form of a set of hook- and-loop straps or in other forms known to the person skilled in the art.
  • they are indeed capable of adjusting the relative position of the flaps of the inner liner - and thus adapt the inner volume of the inner liner to the user's foot - near their position, i.e., near the longitudinal front opening of the inner liner.
  • Document DE 203 13 763 U describes a boot for winter sports practice comprising an outer shell and an inner liner and provided with a lacing system for the inner liner.
  • Said lacing system for the inner liner comprises a plurality of loops arranged on the inner liner and at least one loop arranged on the outer shell, so that the user's foot is held not only against the inner liner, but also against the outer shell.
  • Document US 2019/313740 discloses a trekking footwear comprising a sole, an upper provided with a lacing system, and a rigid holding cage comprising support members extending upwards from the support plate, forming a portion of cradle around and rearward of a wearer's calcaneus bone. Said support members are joined to the lacing system so that a forward force of a wearer's instep is transmitted to the rigid holding cage.
  • Document DE 202 19 913 U describes a footwear having a sole and an upper, the upper comprising an elongated opening extending substantially from its rear end to its front end and allowing easy access to the inner face of the upper for cleaning thereof.
  • the upper is further provided with a lacing system comprising a plurality of loops attached to said upper and a lace passing through said loops.
  • the main object of the present invention is therefore to provide an inner liner for a ski boot that is provided with a tightening system allowing proper tightening of the upper of the inner liner over the user's foot.
  • the main object of the present invention is to provide an inner liner for a ski boot that is provided with a tightening system allowing proper tightening of the upper of the inner liner over the user's foot at the heel region.
  • the invention relates to an inner liner for a ski boot as claimed in claim 1.
  • Said inner liner comprises, on each of the sides (i.e., the lateral side and the medial side), one or more tie members extending from the heel region to the instep region, each of said tie members having a first end facing said heel region and a second end facing the instep region.
  • the second end of each tie member is free with respect to the upper of the inner liner, and the inner liner comprises tensioning means arranged to exert a traction force onto said second end of said tie members.
  • the heel region of the upper of the inner liner can be pulled towards the instep region of the upper of said inner liner until it perfectly adheres to the user's heel.
  • each tie member facing the heel region is fastened to the upper of the inner liner.
  • the first end facing the heel region of each tie member on the lateral side of the upper of the inner liner is joined to the first end facing the heel region of a corresponding tie member on the medial side of said upper of said inner liner.
  • the upper of the inner liner is provided with a longitudinal front opening extending from the toe region to the ankle region through the instep region and comprising a tightening system arranged along said longitudinal front opening of said inner liner, said tightening system acting as tensioning means for said tie rods.
  • said tightening system is a lacing system comprising one or more laces passing through eyelets arranged along the opposite sides of said longitudinal front opening, and the second ends of the tie rods are constrained to said one or more lace(s) of said lacing system.
  • said tie members are made as strings or tapes or comprise strings or tapes.
  • said tie members are made as rigid rods or comprise rigid rods.
  • tie members will be made of a less yielding material than the material of the inner liner, so that they can properly exert an action of traction onto the heel region of said inner liner without becoming deformed and thereby losing efficacy.
  • the present invention further relates to a ski boot comprising an outer shell, made of a substantially rigid material, and an inner liner as described above.
  • Figure 1 schematically shows an inner liner 1 for ski boots.
  • the inner liner 1 comprises a sole 3 and an upper 5.
  • the inner liner 1 comprises a longitudinal front opening 7 extending from the toe region 5a to the ankle region 5d through the instep region 5b.
  • Said longitudinal front opening 7 defines, in the upper, two opposite and facing and is preferably covered by a front tongue 9.
  • said inner liner is provided with a tightening system 11 arranged at the longitudinal front opening 7.
  • said tightening system is made as a lacing system 11 and comprises a lace 13 passing through eyelets 15 arranged on the edges of the opposite and facing flaps of the upper 5.
  • the tightening system may also be implemented in any other way known to the person skilled in art.
  • the user can bring the two opposite and facing flaps of the upper 5, until said upper suitably envelops the user's foot.
  • the lacing system 11 thus makes it possible to adjust the relative position of the flaps of the upper of the inner liner and thus adjust the inner volume of the inner liner to the user's foot at the toe region 5a, the instep region 5b and the ankle region 5d.
  • a low adherence of the inner liner 1 to the user's heel i.e., the presence of a gap between the user's heel and the heel region 5c of the upper of the inner liner
  • the inner liner 1 comprises, on each of the sides, i.e., the lateral side and the medial side, of the upper 5, one or more tie member(s) 17 extending from the heel region 5c to the instep region 5b.
  • tie members 17 are illustrated.
  • the two tie members are both arranged from the heel region 5c to the instep region 5b, but they have different inclinations, and in particular they converge towards the instep region 5b.
  • Said arrangement (also extendable to a number of tie members higher than two) is particularly advantageous for effectively exerting a traction on the heel region 5c of the upper 5 towards the user's heel.
  • said arrangement should not be regarded as limiting and it is also possible, for example, to envisage two or more tie members extending parallel to each other from the heel region 5c to the instep region 5b.
  • the number of tie members on the lateral side and medial side of the inner liner can be the same or different.
  • the tie members on the lateral side and those on the medial side can be arranged either symmetrical or non-symmetrical relative to a plane of symmetry passing through the longitudinal front opening 7 of the inner liner 1.
  • Each tie member 17 has a first end 17a facing the heel region 5c of the upper 5, and a second end 17b facing the instep region 5b of the upper 5.
  • Each tie member 17, at its first end 17a, is fixed to the upper 5 of the inner liner 1, in particular at the heel region 5c of the upper 5; to this aim, a heel reinforcement 19 may be provided at the heel region 5c, and the first end 17a of each tie member 17 is fixed to said heel reinforcement 19.
  • the second end 17b of each tie member 17 is free.
  • the inner liner 1 further comprises tensioning means exerting a traction force onto the second end 17b of each tie member 17.
  • tensioning means exerting a traction force onto the second ends of the tie members.
  • said tie members will be pulled towards the instep region and "drag" with them the heel region 5c of the upper 5, bringing said heel region close to the instep region 5b.
  • any gaps that may exist between the inner liner 1 and the user's foot - particularly at the user's heel - will be compensated for, and the inner liner will adhere to the user's foot also at the heel region.
  • the tightening system 11 arranged at the longitudinal front opening 7 acts as tensioning means for the tie members 17.
  • the lacing system 11 acts as tensioning means for the tie members 17.
  • a loop 21 is associated with the second end 17b of the tie members 17, and the lace 13 passes through said loop 21.
  • each of the tie members 17 arranged on the same side of the upper is provided with its own loop.
  • the tie members converge towards and are associated with a common loop 21, as shown in Figure 1 .
  • the tie members 17 may be made as strings or tapes, as shown in Figure 1 , or they may in any case comprise a string or tape over a portion thereof.
  • the tie members may be made as rigid rods, or in any way comprise a rigid rod or a similar rigid member over a portion thereof.
  • the tie members 17 are made of a material that is less yielding than the material of the upper 5, so that they can properly exert a pulling action on the heel region 5c of said upper.
  • the tie members 17 extend outside the upper 5 between the first and second end 17a, 17b and adhere to said upper.
  • the tie members 17 extend at least partly inside the upper 5 and to this aim one or more channels 23 (a single channel 23 in Figure 1 ) are provided in the upper 5, said channels being arranged along the path of the tie members 17, so that the tie members, by penetrating into said channels, pass from the outer side of the upper to the inner side of the upper.
  • a path of the tie members 17 that is arranged partly outside the upper and partly inside the upper may advantageously make it possible to increase the efficiency in ensuring adhesion of the upper of the inner liner 1 to the user's foot, especially at the heel region, but also at the path of the tie members between the heel region and the instep region (thus essentially at the malleolar region).
  • Figures 2a and 2b show a view of the lateral side and a view of the medial side of an inner liner 1' according to a further preferred embodiment of the invention.
  • the inner liner 1' comprises a sole and an upper 5' and differs from the previously described inner liner in that it consists of two different components, combined together to give the overall shape of said sole and said upper.
  • the inner liner 1' consists of a front component 1a', in which the toe region 5a' and an instep region 5a" are defined, and a rear component 5b', in which the heel region 5c' and the ankle region 5d' are defined.
  • the inner liner 1' comprises a longitudinal front opening 7', which in this case extends only along the front component 1a', and a lacing system 11' extending along said longitudinal front opening 7' and comprising a lace 13' passing through eyelets 15'.
  • the inner liner 1' comprises on each of the sides - i.e., the lateral side and the medial side - of the upper 5' one or more tie members extending from the heel region 5c' to the instep region 5b'.
  • a single tie member 17l' is provided on the lateral side of the upper 5' and, accordingly, a single tie member 17m' is provided on the medial side of said upper.
  • Each tie member 17l', 17m' has a first end 17al', 17am' facing the heel region 5c' of the upper 5' and a second end 17bl', 17bm' facing the instep region 5b' of the upper 5'.
  • the second ends 17bl', 17bm', facing the instep region 5b', of the tie members 17l', 17m' are connected to the lacing system 11' acting as tensioning means for said tie members.
  • first ends 17al', 17am' of each tie member 17l', 17m' are not fixed to the upper; instead, said first ends 17al', 17am' are joined to each other by means of a joining element 25'.
  • Said joining element 25' is made of a substantially inextensible material and passes under the sole of the inner liner 1'.
