| Abstract: |
A lightweight vehicle which utilizes a single large wheel in the rear that carries most of the weight with a single small wheel in front for guidance. The driver's seat is normally positioned immediately in front of the large wheel and the engine is positioned immediately to the rear of the large wheel, with the center of mass of the vehicle being below and forward of the axle of the large wheel. The passenger seat is connected to a frame extending between the two wheels by a parallelogram type linkage which connects to a bumper extending in front of the vehicle. The linkage is arranged such that on impact of the bumper, the parallelogram linkage causes the seat to move upwardly and tilt backwardly over the top of the large wheel to help protect the driver in the event of a crash.
