Abstract:
A two stage resistance generating system for exerting resistance to a moving surface comprising:at least one resistance pad which exerts a resistance force upon the moving surface when said resistance pad is biased against the moving surface;said resistance pad comprising at least one foam pad and at least one piece of resistance material wherein at least one said foam pad is located between at least one said piece of resistance material and said biasing force such that said resistance material makes contact with said moving surface, andan actuation means which exerts the biasing force upon said resistance pad causing increased resistance to motion of the moving surface such that the increase in resistance to motion exerted upon the moving surface is exerted in two stages, wherein the ratio of resistance to motion imparted against the moving surface in relation to the amount of biasing force is higher for stage two than for stage one.
