Abstract

Ski boot with improved lateral support including a shell connected to a quarter and having a rigid element which is monolithic or formed integrally with the shell and at least partially affects the inner side of the foot and leg and the plantar arch. The boot allows to achieve optimum ski control by distributing the efforts and ensuring rear support.

Claims

1. In combination, a ski boot having a shell defining a heel region, a malleolar region, a metatarsal region, a plantar arch, a foot inner side and a foot outer side, and a quarter connected to said shell and defining a leg inner side and a leg outer side, and

a rigid lateral support element comprising;

a first flap connected to said ski boot and located adjacent said foot inner side of said shell and said leg inner side of said quarter;

a first wing defined by said first flap and extending from said heel region to said metatarsal region at said foot inner side of said shell, and;

an arm extending from said first wing beneath said plantar arch, and

stud means connecting said quarter to said shell and fixing said first flap of said rigid lateral support element to said leg inner side of said quarter and to said foot inner side of said shell.

2. The combination according to claim 1, further comprising a second flap connected to said first flap and located adjacent said outer leg side of said quarter, said second flap having an end, said end of said second flap being connected to said malleolar region of said shell by said stud means.

3. The combination according to claim 2, further comprising a first bridge, first wing defined by said first flap and extending from said heel region to said metatarsal region at said foot inner side of said shell, and a second wing defined by said first flap of said rigid lateral support element, said first bridge interconnecting said second wing of said first flap and said second flap.

4. The combination according to claim 3, further comprising a second bridge, said second bridge being located below said first bridge and interconnecting said second wing and said second flap at a location overlying said heel region of said shell.

5. The combination according to claim 4, wherein said first wing and said second wing of said first flap, said arm, said second flap, said first bridge and said second bridge are formed monolithically.

6. The combination according to claim 1, further comprising;

a second wing defined by said first flap at said leg inner side of said quarter;

an upper perimetric edge defined by said quarter;

an opening formed on said second wing above said upper perimetric edge, and;

a lug protruding from said shell into said opening formed on said wing.

7. The combination according to claim 1, further comprising;

a second wing defined by said first flap;

a curved slot formed on said second wing, and;

a lug protruding externally from said quarter and slidingly engaging said curved slot in said second wing;

wherein said quarter is rotatable with respect to said shell about said stud means, and wherein rotation of said quarter with respect to said shell is limited by movement of said lug in said curved slot.

8. In combination, a ski boot having a shell defining a heel region, a malleolar region, a metatarsal region, a plantar arch, a foot inner side and a foot outer side, a quarter defining a leg inner side and a leg outer side, and stud means connecting said quarter to said shell, and

a rigid lateral support element comprising;

a first flap connected to said ski boot and located adjacent said foot inner side of said shell and said leg inner side of said quarter;

a first wing defined by said first flap and extending from said heel region to said metatarsal region at said foot inner side of said shell, and;

an arm extending from said first wing beneath said plantar arch and extending along said plantar arch from a zone located below said malleolar region of said shell to a zone located below said metatarsal region thereof,

wherein said first flap of said rigid lateral support element is fixed to said leg inner side of said quarter and to said foot inner side of said shell by said stud means.

9. The combination according to claim 8, further comprising a second flap connected to said first flap and located adjacent said outer leg side of said quarter, said second flap having an end, said end of said second flap being connected to said malleolar region of said shell by said stud means.

10. The combination according to claim 9, further comprising a first bridge, and a second wing defined by said first flap of said rigid lateral support element, said first bridge interconnecting said second wing of said first flap and said second flap.

11. The combination according to claim 10, further comprising a second bridge, said second bridge being located below said first bridge and interconnecting said second wing and said second flap at a location overlying said heel region of said shell.

12. The combination according to claim 11, wherein said first wing and said second wing of said first flap, said arm, said second flap, said first bridge and said second bridge are formed monolithically.

13. In combination, a ski boot having a shell defining a heel region, a malleolar region, a metatarsal region, a plantar arch, a foot inner side and a foot outer side, a quarter defining a leg inner side and a leg outer side, and stud means connecting said quarter to said shell, and

a rigid lateral support element comprising;

a first flap connected to said ski boot and located adjacent said foot inner side of said shell and said leg inner side of said quarter;

a first wing formed monolithically with said first flap and extending from said heel region to said metatarsal region at said foot inner side of said shell, and;

an arm formed monolithically with and extending from said first wing beneath said plantar arch and extending along said plantar arch from a zone located below said malleolar region of said shell to a zone located below said metatarsal region thereof,

wherein said first flap of said rigid lateral support element is fixed to said leg inner side of said quarter and to said foot inner side of said shell by said stud means.

14. The combination according to claim 13, further comprising a second flap formed monolithically with said first flap and located adjacent said outer leg side of said quarter, said second flap having an end, said end of said second flap being connected to said malleolar region of said shell by said stud means.

15. The combination according to claim 14, further comprising a first bridge, a second bridge, and a second wing defined by said first flap of said rigid lateral support element, said first bridge interconnecting and formed monolithically with said second wing of said first flap and said second flap, said second bridge being located below said first bridge and being formed monolithically with and interconnecting said second wing and said second flap at a location overlying said heel region of said shell.
