  • the arms are bent with legs 120 terminating in free ends. Covers are provided over the free ends.
  • Narrow skis, 63 - 68 mm at the waist have dominated the ski industry since the beginning. This width performs best on groomed runs, and especially on hard snow and ice. Because of the precise edge control and grip on ice, World Cup racers typically use skis that are 67 or 68 mm wide.
  • narrow skis lack flotation and are more difficult and tiring to use in soft snow conditions.
  • Mid-Fat skis from around 70 mm at waist to around 88 mm at waist, are currently the ski of choice for the all mountain skier. These are a compromise in all dimensions, but will give better performance in soft snow than a narrow ski without sacrificing too much edge grip and precision on hard snow.
  • Wide skis around 80 mm to over 130 mm at waist, are the best tool for soft snow and deep powder. The wider the skis are, the more flotation they deliver, and they make skiing powder easier for everyone. The problem here is that the wider the ski, the more difficult it is to get on edge and control edge angle, making them difficult and tiring to use on hard snow conditions.
  • ski industry has been selling skis based on the percentage of time one spends on groomed runs vs. ungroomed runs, recommending "mid fat” skis for most skiers. This is a compromise in performance under most snow conditions. For example, a skier who spends approximately 75 percent of his time on groomed runs should opt for a ski in the narrow range of the "mid- fat” category, while a skier who spends 75 percent of his time skiing the back bowls should select something wider.
  • Narrow skis and wide skis are now largely considered to be specialized equipment and are used by the purist seeking optimal performance in one particular type of snow conditions. Many times these skis are used by skiers who own more than one pair of skis.
  • the off-center mounting on the present invention eliminates the compromise. It gives the skier the edge grip and precision of a narrow ski on hard snow, and the flotation and ease of a wide ski in soft snow. This is done by using a ski from the "wide" category and mounting the bindings off-center to position the inside edges of the ski boots over the inside edges of the skis. The reason that this works is because when skiing hard snow, 90 percent of a skiers edging power comes from the downhill ski--the inside edge. Mounting the bindings in this manner allows the skier to edge the skis easily and precisely on hard snow and ice--they ski and feel just like narrow skis. Yet, when skiing powder, they float and feel just like wide skis, because they are side skis! No compromises.

Abstract

La présente invention concerne un ensemble frein (36) positionné sur la surface supérieure (22) d’un ski (12). L’ensemble frein comporte une plaque fixe (38) et une plaque mobile (46). Des paires de doigts avant et arrière (54, 56) raccordent les plaques. Les doigts avant présentent des extrémités supérieures (58) raccordées de manière pivotante à la plaque mobile. Les doigts avant présentent des extrémités inférieures (60) dotées de bras s’étendant vers l’extérieur et pouvant pivoter par rapport à la plaque fixe. Les bras s’étendant vers l’extérieur comportent un bras court (62) s’étendant sur une première distance en direction d’un bord intérieur (18) d’un ski. Les bras s’étendant vers l’extérieur comportent un bras long (64) s’étendant sur une seconde distance supérieure à la première distance par rapport au bord extérieur (20) d’un ski. Les bras se terminent avec au moins une patte de freinage (66, 68) s’étendant vers l’arrière et conçue pour s’étendre vers l’arrière lorsque la plaque mobile se trouve dans la position abaissée de non-fonctionnement et pour s’étendre vers l’arrière et vers le bas lorsque la plaque mobile se trouve dans la position soulevée de fonctionnement.
