Abstract
A safety ski binding has a bearing block with a locking projection, and a sole holder is supported on the bearing block for pivotal movement between a downhill skiing position and a released position. A locking part pivotally supported on the sole holder has a cam which engages the locking projection and has a surface on the opposite side thereof. a spring housing has one end pivotally supported on the bearing block and has an opening in the opposite end. A piston slidably supported in the spring housing has a piston rod which extends through the opening and slidably engages the surface on the locking part. A spring disposed in the spring housing urges the piston toward the locking part, thereby urging the cam against the locking projection. A mechanism is provided to obstruct sliding movement of the piston rod along the locking part surface from a first location thereon to a second location in which the effect of the spring on the locking part is reduced or absent. A manually actuable mechanism is provided for temporarily rendering the obstructing mechanism ineffective.
