Vehicle flooring comprising either a floor formed by longitudinal flat elements (50) bordered by so-called "shaft" members (51) and/or "ISO cross bars" (52) and supported by cross bars (18) resting perpendicularly on two so-called "sub frame" longitudinal members (18) in turn fixed on the side-members of the vehicle chassis, or a floor formed by transverse flat elements (50) resting perpendicularly on two so-called "sub frame" longitudinal members in turn fixed on the side members of the vehicle chassis, characterised in that the longitudinal or transverse flat elements (50) are tubular shaped sections with a substantially flat upper profile (1) and an undulating lower profile (2) possessing, on each side, two longitudinal U-shaped branches (5, 6, 7, 8) (male and female) allowing two adjacent shaped sections to nest with a variable lateral clearance.</p> |
