<p>A sidewall construction for a bus having several fitted sections and seats mounted on the wall. A seat fastening strap is attached to a support tube of the seats and extends downward. One of the sections of the sidewall structure, particularly the bottom arch section at the level of the lower end region of the seat fastening strap, has an angle-shaped recess open at the rim and facing the seat fastening strap. The recess has a hanger bar for hanging the seat fastening strap, and a screw lock for disconnectably fixing the seats in place. The recess has an L-shaped cross-section at the open rim, and two arms connect at right angles to this cross-section. The arms correspond, on one hand, with the seat fastening strap, and, on the other hand, they correspond to a screw bolt passing at right angles through the seat fastening strap. One of the arms extends at right angles upward from the hanger bar for hanging the seat fastening strap, and the other arm is an upper horizontal arm facing the recess on its inside and has a threaded groove corresponding to the thread of the screw bolt. The L-shaped cross-section of the recess, in the region corresponding to the face surface of the shank of the screw bolt, has one or several ribs which, together with the screw bolt, form a lengthwise lock for the seats.</p> |
