  • Method and apparatus for easing the strain on legs and knees while on a ski lift
    Patent number: 5653467
    Abstract: A method and apparatus for supporting the weight of legs, boots, and skis of a skier while riding on a ski lift chair which uses a support strap (24) of elongated flexible material attached at one end to each boot in conjunction with a boot attachment strap (20). The other end of the support strap (24) extends up the back of a skier's leg to at least the back of the thigh area. The support strap (24) attaches to either a pull tab (30), a reel (42), an elastic strap (76) or an elasticized cord (50) which draws taut the support strap against the front edge of the chair seat (24) so as to slightly elevate the skier's legs, boots, and skis and support their weight. Either the weight of the thigh and buttock (34) on the support strap (24), a gear lock (46) on the reel (42), or a union between a hook tab (56) which attaches to the support strap (24) and a pile strip (58) which attaches to the ski apparel holds the support strap (24) taut and holds the supported weight of the legs, boots, and skis of a skier.
