Claim 20

The skier body weight support system of claim 9 wherein each of said first and second support means comprises at least one elongated frame-like member.

Claim 21

The skier body weight support system of claim 19 wherein each of said support means comprises a pair of generally parallel elongated, frame-like members having webbing means interposed therebetween for engaging an associated portion of the leg of the skier.

Claim 22

Claim 24

The skier body weight support system of claim 20 wherein said first support means includes strap means for strapping said first support means to the thigh just below the buttocks and just above the knee and wherein said second support means includes strap means for strapping said second support means to the calf just below the knee.

Claim 25

The body weight support system of claim 23 wherein said strap means for securing said second mounting means to said boot is adjustably mounted on said second support means to provide an optimal interface with said boot.

Claim 26

The skier body weight support system of claim 9 wherein said flexure means includes adjustment means located adjacent the upper end of said first support means for establishing said predetermined angular flexure range.

Claim 27

The skier body weight support system of claim 9 wherein said first and second support means and said flexure means are arranged to be worn over a garment on the leg.

Claim 28

The skier body weight support system of claim 9 wherein said first and second support means and said flexure means are incorporated in a garment worn on the leg. .Iadd.

Claim 29

A body joint support for limiting angular movement of a selected joint of the body to a preselected range of angular motion, comprising: a. a longitudinally elongated flexible central support member; b. a plurality of members adjacent to one another and extending in cantilever fashion from a common side of said central support member in a direction interior to the angle through which said selected joint moves, adjacent ones of said members being spaced from one another when said central support member is essentially unflexed and said selected joint is at a corresponding first end of said preselected angular range and adjacent ones of said members interferingly contacting one another to prevent further angular, flexure of said central support member when said central support member is flexed to an extent corresponding to said selected joint being at a second end of said preselected angular range; c. first support means extending away from said central flexible support member at a first end thereof and adapted for securement to a portion of the body extending away from said joint in a first direction; d. second support means extending away from said central flexible support member at a second end thereof and adapted for securement to a portion of the body extending away from said joint in a second direction generally oppositely disposed to said first direction. .Iaddend. .Iadd.29.
