Abstract
Abstract I have devised a force modulating device, for use as a force modulating member of a ski device, in which I have made a first member thereof to be movably interconnected with a body member of the force modulating device and I have disposed therebetween fluid pressure medium for floating the first member with respect to the body member and controlling the relative movement between such two members. The fluid pressure medium can be a gas, a liquid or a combination gas and liquid. The fluid pressure medium can be provided with a member for communicating with a fluid pressure supply source, illustratively located off of the ski, permitting external manual or automatic adjustments or changes to the fluid pressure to be made after a ski device incorporating this invention has been fabricated so as to optimize the force modulating capability of the ski device for a particular user load and use.
