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.
