Multidirectional release safety ski binding

A safety ski binding comprising:

• a vertical pivot member adapted for mounting on and substantially perpendicular to the surface of a ski and defining a vertical axis, said pivot member including a pair of diametrically opposed cam means;
• a body rotatably mounted for pivotal movement about said vertical pivot member in a first direction substantially parallel to the surface of the ski;
• a rigid end piece for cooperative engagement with one end of a ski boot and pivotally connected to said body about a horizontal axis lying transverse to the elongation of the ski for pivotal movement in a second direction substantially perpendicular to the surface of the ski and said first direction, said end piece including at least one ramp;
• a pair of pistons movable in the longitudinal direction of the ski;
• a resilient member interposed between said pistons for urging each said piston into engagement with a respective one of said cam means;
• and
• a follower disposed for engagement with said at least one ramp of the end piece and with one of said pistons and for relative movement with respect to said body such that said follower causes movement of said one piston away from the associated cam means on pivotal movement of said end piece about said horizontal axis.
