Abstract

The rigidity of a high performance ski boot is increased by forming interlocking connections between a front tongue, a footbed and a rear ankle portion of the boot. Such connections are particularly effective in reducing or eliminating transverse spreading or sideward flaring of the front tongue as a skier leans forwardly against the tongue during aggressive ski maneuvers. By eliminating such transverse flaring and distortion, the foot support and overall performance of the boot is increased.

Claims

1. A ski boot, comprising:

a footbed comprising an edge portion having a width bounded on opposite sides by an inner surface and an outer surface, said inner and outer surfaces defining a portion of a footbed sidewall;

a front tongue member movably connected to said footbed and comprising a tongue member edge portion releasably engagable with said footbed edge portion;

a pair of lips projecting outwardly from said tongue member for providing a rigid mutually-reinforcing interengagement between said footbed and said tongue member, said lips being spaced apart greater than the width of said footbed edge portion and said tongue member edge portion so as to overlap said inner and outer surfaces of said sidewall such that said interengagement comprises a rigidity greater than the rigidity of either one of said footbed edge portion and said tongue edge portion; and

a rear ankle member extending from said footbed, said rear ankle member comprising a front edge portion defining inner and outer surface portions, said front tongue member further comprising an upper tongue edge portion and a wall portion extending from said upper tongue edge portion, and alignment means defined between said front edge portion of said rear ankle member and said upper tongue edge portion, said alignment means directing said wall portion of said upper tongue edge portion over said outer surface portion of said front edge portion of said rear ankle member.

2. The ski boot of claim 1, wherein said rigid interengagement comprises a channel formed in said edge portion of said front tongue member.

3. The ski boot of claim 1, wherein said rigid interengagement comprises tab means.

4. The ski boot of claim 1, wherein said footbed comprises a rigid front nose portion and wherein said front tongue member is pivotally connected to said footbed at said front nose portion.

5. The ski boot of claim 1, wherein said lips define a groove therebetween.

6. The ski boot of claim 5, wherein said interengagement is defined between said footbed edge portion and said groove.

7. A ski boot, comprising:

a footbed comprising an edge portion having a width bounded on opposite sides by an inner surface and an outer surface, said inner and outer surfaces defining a portion of a footbed sidewall;

a front tongue member movably connected to said footbed and comprising a tongue member edge portion releasably engagable with said footbed edge portion, said tongue member edge portion having a width bounded on opposite sides by inner and outer surfaces defining a portion of a tongue wall;

a pair of lips projecting outwardly from said footbed edge portion for providing a rigid mutually-reinforcing interengagement between said footbed and said tongue member, said lips being spaced apart greater than the width of said footbed edge portion and said tongue member edge portion so as to overlap said inner and outer surfaces of said tongue wall such that said interengagement comprises a rigidity greater than the rigidity of either one of said footbed edge portion and said tongue member edge portion; and

a rear ankle member extending from said footbed, said rear ankle member comprising a front edge portion defining inner and outer surface portions, said front tongue member further comprising an upper tongue edge portion and a wall portion extending from said upper tongue edge portion, and alignment means defined between said front edge portion of said rear ankle member and said upper tongue edge portion, said alignment means directing said wall portion of said upper tongue edge portion over said outer surface portion of said front edge portion of said rear ankle member.
