Patent ID: 7669864

Claim:
A wheeled vehicle which includes: two frames for carrying road wheels, the frames being laterally spaced apart; a pair of road wheels, including a front road wheel and a rear road wheel, mounted on each frame for supporting that frame on the ground, the wheels of each pair being mounted for rotation about operatively more or less horizontal axes or rotation, and being spaced apart along the associated frame; and a motor which is connected by a drive train to at least one wheel on each of the wheeled frames, the wheeled frames being connected together for synchronous lateral tilting relative to the vertical, so that the camber angle of each wheel changes in response to tilting of the frames, the front wheels being operatively connected to a driver operable steering mechanism for synchronous pivotal displacement about respective steering axes; and a seat frame positioned between the wheeled frames, the seat frame being connected to the wheeled frames such that the seat frame is clear of the around and is configured for synchronous tilting with the wheeled frames, the seat frame providing a seat for a driver of the vehicle, wherein the wheeled frames and the seat frame are connected together by a plurality of laterally extending link members, each lateral link member being connected to both wheeled frames and to the seat frame, each connection being such as to permit pivotal displacement of the link member relative to the respective frame about a pivot axis which is aligned with the fore-and-aft direction of the vehicle, and the link members comprise two link bars which are located at a relatively high level and which are spaced apart in the fore-and-aft direction of the vehicle, and a platform member which is located at a relatively low level and provides a support surface for the feet of a driver seated on the seat frame.
