Abstract: A motor vehicle has a door opening adjacent an occupant seat and a cowl structure extending transversely across the vehicle body forward of a windshield opening. A door provided for closing the door opening is mounted on a door support arm having an inboard end pivotally mounted on the cowl structure and an outboard end connected to the door so that pivotal movement of the support arm bodily swings the door vertically between a lowered closed position and a raised open position. The support arm is preferably mounted on the vehicle cowl structure by a pivot located closely adjacent the center line of the vehicle body and the support arm is configured to fit flush with the surface of the cowl structure and hood of the vehicle body.

Abstract: An articulated cambering vehicle in which a pair of trailing arms are interconnected to each other and to a front steering frame by a hydraulic stabilizer and equalizer providing: stabilization of the steering frame, the equal and opposite movement of the arms during cambering operation, the hydraulic locking of the trailing arms to the front steering frame for vehicle parking, and the folding and locking of the front steering frame intermediate the trailing arms for vehicle stowage purposes.
