Abstract: A bus frame including a floor frame and a roof frame, the roof frame including a three-dimensional longitudinally continuous framework occupying at least a portion of the total roof frame width. The three-dimensional framework fits along the corners of the bus formed where the roof and side walls of the bus meet. The outer contour of the framework has the form of a triangular prism, one face of the prism coinciding with the bus roof, and another face coinciding with a bus side wall. The prism-shaped framework is defined in part by a series of triangular transverse members, each member being in a plane normal to the longitudinal centerline of the bus. The diagonally-oriented frame members, which face the interior of the bus, carry retaining elements for holding trim panels.

Abstract: Disclosed is a passenger vehicle, comprising a tubular metal frame, including two spaced vertical side members and an upper and a lower longitudinal member intersecting the vertical side members to define a window opening, at least the side members comprising a hollow cross-section and an integrally-formed bead portion projecting into the window opening; a pane of essentially transparent material positioned in the window opening and abutting against the bead portions; and an adhesive or other means for bonding the pane to the bead portions. The frame members may have a cross-section which is L-shaped, T-shaped or generally rectangular with an integrally formed protrusion.

Abstract: A multi-passenger vehicle such as a bus has a lateral entry and exit door which opens a stairwell. One or more passenger seats are arranged immediately adjacent to the stairwell. The passenger seat is oriented in such a manner relative to the longitudinal axis of the bus that the passenger either faces in the travel direction or in the opposite direction. A foot rest plate covers the stairwell when the door is closed. The foot rest plate is hinged about a horizontal axis extending across the longitudinal axis of the bus. In the upwardly tilted position the foot rest plate does not interfere with the free use of the stairwell for its purpose and in the closed position the foot rest plate makes the particular seat adjacent to the stairwell as comfortable as any other seat in the bus.
