  • Patent number: 6431562
    Abstract: The ground gliding vehicle has a gliding part (1) facing the ground, a supporting structure 2 placed upon it and a seating structure (3) attached to this supporting structure (2). On the supporting structure (2) and/or on the seating structure (3), means (5) for holding on are attached. The supporting structure (2) is equipped with a shock absorber (4) for absorbing bumps of the ground during a ride. The seating height (H) is adjustable by virtue of the fact, that the shock absorber (4) can be attached to several points (12.1-12.3) on the gliding part (1). The ground gliding vehicle can be folded up, in order to occupy less volume during transportation. When driving, the driver in essence sits upright on the seating structure (3) and looks in the direction of travel (x), so that his feet touch the ground each on one side of the gliding part (1). The driver can wear short—or extremely short skis on his feet. The ground gliding vehicle is steered mainly by the transfer of weight.
