ABSTRACT:
A field-adjustable load-absorbing spring plate for skis, which spring plate pivotally mounts to an upper surface of a ski for relative vertical movement of the spring plate in response to inflation of an air bladder disposed between the upper surface of the ski and the spring plate and in response to loads imposed on the ski by the skier while skiing. An air pump connects by an air pipe to the air bladder and a valve operatively connected between the air pump and the air pipe is movable between a closed position and an open position the valve is selectively operable for communicating air under pressure from the pump into the air bladder and for communicating air from the air bladder to atmosphere. Side wallls extend downwardly on opposite longitudinal sides of the spring plate for holding the air bag in position between the ski and the spring plate. Spaced-apart lines in a surface of a forward hinge plate covered or uncovered by a measuring plate as the hinge plate moves in response to changing the pressure of air in the air bladder to provide a relative measure of the pressurization of the air bladder. An opening defined in a rear portion of the spring plate communicates snow from around the air bladder outwardly of the ski.
