Abstract: A vehicle has a chassis providing a drier compartment and includes a door frame about an opening into the driver compartment. A door is cooperatively dimensioned and configured to close the opening, and is pivotably mounted on the door on the forward portion of the door frame by a hinge. The hinge includes a pivot pin having a pivot axis angled rearwardly and outwardly. The door pivots upwardly and forwardly about the pivot pin during opening movement. Upward opening of the door is facilitated by the inclusion of a spring arragement biasing the door into an open position.

Abstract: A motorcycle backrest has a back support cushion with a handhold aperture, and a support arm mounting for mounting the back support cushion on the motorcycle saddle or frame. The backrest can simultaneously function as a comfortable back support for the driver and a convenient handhold for the passenger.

Abstract: An adjustable fairing for a motorcycle has a fairing body, a pivot assembly for mounting the fairing body on the vehicle, and an adjustment knob operative on the pivoting assembly for adjusting the angle of the fairing body while the motorcycle is in operation.

Abstract: A vehicle has a chassis with at least one front wheel pivotable about a first vertical axis to control the direction of the vehicle. A rigid swing arm is pivotally mounted on the rear end of the chassis for pivoting about a horizontal axis. On the rear end of the swing arm is a wheel mounting assembly including a hub and pivot means mounting the hub on the rear end of the swing arm for pivotal movement about a second vertical axis. The rear wheel is rotatably supported on the hub and naturally tracks the front wheel in a cooperating turning arc.

Abstract: A tandem motorcycle saddle and backrest has a backrest mounting unit embedded in the cushioning material in the front section of said passenger seat portion. The unit has a housing with a slot in the top wall, and a pivotable member pivotably mounted in the housing for movement in a path along the slot. A spring means biases the pivotable member about the pivot in a rearward direction to an upright position as oriented on the motorcycle, and a stop element limits movement in the rearward direction. The fabric covering and cushioning material have openings therein aligned with the housing slot. The backrest has an elongated rigid support arm having its lower portion extending through the opening in the slot, and removably seated in the pivotable member. The backrest is pivotable in a forward direction against the biasing pressure of the spring.

Abstract: A three-wheeled, battery-powered personal vehicle has a single rear wheel at the end of a swing arm pivotally supported on the vehicle chassis. A motor, also pivotally supported on the chassis, pivots about the same axis as the swing arm, pivots and powers the rear wheel through a endless drive member. The chassis is provided by a lightweight, synthetic resin tub with substantial structural rigidity. The upper body is a separate synthetic resin tub which can be nested within the chassis for shipment and readily assembled thereto at the point of sale. The assembled chassis and upper body define a generally ovoidal configuration. Batteries are carried in a front compartment and provide crash protection for frontal impacts and other batteries are located beneath the vehicle seat to provide a low center of gravity. Transversely extending chassis members provide structural stiffness as well as support elements for the assembly.

Abstract: A two-part seat assembly for a motorcycle like vehicle has an operator's seat that is hingedly mounted to enable adjustment of its angle of inclination, and thereby to enable alteration of the operator's body attitude. Skirt portions are provided on the operator's seat to conceal the mechanism by which adjustment of the seat position is achieved, and to hide the frame parts and the concavity in which the operator's seat resides.
