A support structure of a motor bus comprises a plurality of modular cells each comprising two rectangular end frames made up of two channel section uprights and upper and lower channel section crosspieces, the channels facing axially away from the other frame and having flanges for welding to corresponding members of a contiguous frame of an adjacent modular cell in the structure. Longitudinal reinforcement is provided by longitudinal members at the upper corners which together form a box-section stringer and by channel section stiffeners joining the lower crosspieces. A corrugated panel overlies the lower crosspieces and is joined to them.

A support structure for a motor bus, comprising: a plurality of modular cells connected together in a row extending in the longitudinal direction of the bus, each modular cell including: two rectangular end frames lying in a plane extending transverse the longitudinal axis of said bus, each said end frames being constituted by: an upper horizontal crosspiece, a lower horizontal crosspiece, two upright struts interconnecting respective ends of said upper and lower horizontal crosspieces to define two upper corners and two lower corners, and a pair of upper longitudinal elements and a pair of lower longitudinal elements respectively connecting together said upper corners and said lower corners of said end frames, said horizontal crosspieces and said upright struts of said end frames being of channel section oriented with the channel thereof facing away from the other frame of said cell in the axial direction of said structure, at least some of said horizontal crosspieces and said upright struts having, at least along a substantial part thereof, respective flanges lying in a plane parallel to the general plane of the associated end frame, said flanges on said crosspieces and struts of two adjacent frames belonging to two contiguous modular cells in said support structure being welded together so that said two adjacent frames form a box-section hoop, and box-section reinforcing means interconnecting said modular cells together longitudinally.
