Abstract: The construction incorporating the invention is applied to a utility vehicle such as an open vehicle provided with a fabric top, in which the windshield forms the upper portion of the forward upright of the door frame and portions of the top form the lintel and at least part of the rear upright. An elongate seal member is attached to the inner face of the side edge of the windshield extending throughout its vertical length and is provided with a rearwardly extending rib to sealingly engage a portion of the door. The door comprises a skeletal framework having a border structure conforming to the shape of the door frame and covered with fabric, the framework being made of resilient material. The door is hung on the existing hinge mounts and its lower portion lies in a vertical plane corresponding to that of the lower portion of the door frame. Bends are formed at intermediate points in the height of the framework so that the plane of the upper portion angles inwardly and upwardly.
