Abstract: In a four-seat coupe, it is inconvenient for a rear-seat occupant to get in/out of the vehicle while a front-seat occupant is seated. In the present invention, the length of each door of the four-seat coupe is set, so that the rear-seat occupant can get off/on the vehicle while the front-seat occupant is seated. The door is provided with detachable first opening/closing means at its front and rear end portions. The first opening/closing means at the front end portion of the door is adapted to be released when the front-seat occupant gets off/on the vehicle to allow the first opening/closing means at the rear end portion of the door to support the door so that opening/closing motion can be performed. Also, the first opening/closing means at the rear end portion of the door is adapted to be released when the rear-seat occupant gets off/on the vehicle to allow the first opening/closing means at the front end portion of the door to support the door so that opening/closing motion can be performed.

Abstract: An over the highway vehicle having a body defining an occupant space and an access opening to the space is provided. A passenger access door is pivotally connected to the body. The door has pivotally connected upper and lower sections and is pivotal relative to the body between a closed position and partial and full open positions allowing unobstructed passage into and out of the space. The lower section is pivotal relative to the upper section between an aligned condition for closing the opening and a condition wherein the panels are generally juxtaposed. A tether is interposed between the cab and the lower section for limiting pivotal movement of the door when the door is in its aligned condition to the partially open position and permitting movement of the door to the full open position when the door is in the juxtaposed condition.

Abstract: A utility box, of the type found on utility trucks, having a vertically-openable door which stores by resting on the top of the utility box. The door has as upper segment and a lower segment connected by a first hinge; and the upper segment is connected to the utility box top by a second hinge. The lower segment is about twice the height of the upper segment. Because of this construction, the door may be opened and closed nearby another vehicle or structure, since the maximum horizontal extension needed (from the box) to operate the door is about the same as the height of the smaller upper door segment.
