ABSTRACT:
A safety fixing device for skis permitting automatic re-centering of the ski boot on the longitudinal axis of the ski when fixing said device on the skier's feet while standing up, said device comprising a member adapted to retain one of the extremities of said boot and including a first ramp associated with said boot and a second ramp located on a catch member fixed on said ski, said catch having a portion which is movable between two positions, a first position in which the moving portion of said catch is raised with respect to the ski and a second position in which the moving portion of said catch is locked with respect to said ski, the transition from said first to said second position by the action of pressure of the boot being effected against the force of an elastic member by compressing this latter, the profile of the two ramps in a plane parallel to the ski and to the sole of the boot having substantially the forms of a concave and a convex curve opening out towards the same extremity of the ski, the ramp associated with said boot comprising at least one projecting portion and two sliding surfaces, one said surface being substantially parallel to the boot and directed downwards, the other being inclined with respect to said boot and directed upwards, the ramp located on the moving portion of said catch comprising at least one projecting portion, the ramps associated with the boot and the moving portion of said catch co-operating in such manner that the pivotal movement of the catch causes at least one of the projecting portions of the ramp of said catch to slide over the downwardly-directed sliding surface, while the projecting portion of the ramp associated with said boot slides over the ramp located on the moving portion of said catch.
