Abstract
Ski boot comprising an upper (3) at least partly articulated on a shell base (2), a tightener (15) for closing the boot on the foot, and a sliding block (1) attached in eventually demountable manner on the shell base (2), substantially in the region (22, 70) adjacent to the kick zone, the sliding block being constituted of a thin plate whose form corresponds approximately to the curved surface swept by the periphery of the lower edge (25) of the upper subjected to various flexure movements with respect to the shell base.
Claims8
Ski boot comprising an upper having at least one part which is articulated with respect to a shell base, means of closing said upper on the lower part of the leg of the skier, comprising a sliding block (1) having a curved surface and being located between said upper (3) and said shell base (2) at least in the region substantially corresponding to the instep zone (22, 70) of the boot, the generatrix passing through the median longitudinal plane of said curved surface of said sliding block being approximately concentric to the axis of articulation of said upper on said shell base, said sliding block being compressed in a transverse direction upon flexure of said upper relative to said shell base and constituting at all times a leakproof joint therebetween while also retaining optimal sliding movement during such flexure.
Ski boot comprising an upper having at least one part which is articulated with respect to a shell base, means of closing said upper on the lower part of the leg of the skier, comprising a sliding block (1) having a curved surface and being located between said upper (3) and said shell base (2) at least in the region substantially corresponding to the instep zone (22, 70) of the boot, the generatrix passing through the median longitudinal plane of said curved surface of said sliding block determining a trajectory engaging the lower edge of the forward part of said upper with respect to said shell base, said sliding block being compressed in a transverse direction upon flexure of said upper relative to said shell base and constituting at all times a leakproof joint therebetween while also retaining optimal sliding movement during such flexure.
Ski boot comprising an upper having at least one part which is articulated with respect to a shell base, means of closing said upper on the lower part of the leg of the skier, comprising a sliding block (1) having a curved surface and being located between said upper (3) and said shell base (2) at least in the region substantially corresponding to the instep zone (22, 70) of the boot, the generatrix passing through the median longitudinal plane of said curved surface of said sliding block being approximately concentric to the axis of articulation of said upper on said shell base.
