Safety ski binding

A safety ski binding, comprising a support;

• means for securing said support to a ski;
• a carriage having a boot-supporting portion and front and rear edge portions, as considered in the skiing direction;
• guide means provided on said support and defining for said carriage a path extending substantially transversely of the skiing direction;
• means for yieldably connecting said carriage to said support so that the carriage is fully separable from said support by moving along said path in response to the application of a predetermined force, said connecting means including cooperating first and second components respectively provided solely on said carriage and said support and normally maintaining said carriage in a neutral position above the upper side of the ski carrying said support, said guide means including friction reducing elements on said support and said friction reducing elements including first and second roller bearings having circumferential grooves respectively receiving parts of said front and rear edge portions of said carriage;
• a hold-down device for one end of a ski boot;
• and means for coupling said hold-down device to said carriage.

• a hold-down device for one end of a ski boot;
• and means for coupling said hold-down device to said carriage, said path being an arcuate path having a center of curvature located at the other end of the ski boot whose one end is engaged by said hold-down device, said carriage further including an arcuate portion defining said socket and having a curvature different from the curvature of said path, said projection bearing against said arcuate portion of said carriage upon expulsion from said socket in response to the application of said predetermined force against said carriage.
