Patent ID: 8388013

Claim:
A heel piece for an alpine ski attachment, comprising: a base element ( 1 ), fastenable to a ski (S); an upper element ( 2 ), coupled to the base element ( 1 ); hooking means ( 3 ) borne by the upper element ( 2 ) for hooking to a shaped portion exhibited in a rear part of an alpine ski boot; wherein the hooking means ( 3 ) comprise a pair of arms ( 31 ), constrained to the upper element ( 2 ), said arms being rotatable with respect to the upper element ( 2 ), and a pair of pins ( 32 ) borne by the pair of arms ( 31 ), said pair of pins adapted to project from the upper element ( 2 ) and to face towards a front part (S 1 ) of the ski (S) for hooking the ski boot; elastic means ( 4 ) associated to the upper element ( 2 ), said elastic means adapted to be in contact with the pins ( 32 ) and to maintain the pins ( 32 ) at a predetermined reciprocal distance, said elastic means ( 4 ) being stressable by a separation of the pair of pins ( 32 ), with a consequent rotation of the pair of arms ( 31 ) with respect to the upper element ( 2 ), the separation being determined by a lowering of the rear part of the ski boot onto the ski and by insertion between the pins ( 32 ) of the shaped portion exhibited in said rear part, the pins ( 32 ) being destined, following complete insertion between the said pins ( 32 ) of the shaped portion, to be recalled by the elastic means ( 4 ) to near one another, with a consequent rotation of the pair of arms ( 31 ) with respect to the upper element ( 2 ), in order to lock against an upper part of the shaped portion and thus to hook the ski boot.
