Classes 79 (iv) and 79 (v) In a motor vehicle comprising a middle cell and two end cells, which are separately produced and assembled together to form the vehicle, the frame of the middle cell comprises parallel longitudinal bearers connected by transverse bearers to which are applied the driving and braking forces, forces arising from the road and forces caused by jacking or towing the vehicle. As shown in Fig. 1a the vehicle comprises the three cells A, B. C, the middle cell having its frame comprising the longitudinals a, b, and the tranverse members c, d. The transverse members c, d, are each of arrow head formation and secured in the middle or bent portions c, d are stiffening members f. Secured to one of the members f are a driver's seat, a steering wheel together with gear-change linkage and instruments, the controls pedals being preferably mounted on the member c in front of the seat. Also secured to this member f is the frame of the front part B carrying suspension linkages mI for wheels. Secured to the other member f is a rear seat and the frame of the part C, such frame carrying a power unit x and wheels w. As shown in Fig. 2 the member c is tubular and has each of its ends flattened to form an elliptical section h, which passes through complementary apertures in the box-sectioned longitudinals and is welded thereto at i1, i2, the section h being cut off at j to lie substantially flush with the longitudinal. In a modified arrangement, Fig. 4 (not shown) each longitudinal is formed of upper and lower parts secured together. In a further modification, Fig. 5, the member c is conically flattened at h1, and the part h2 passing through the longitudinal is of elliptical section. Specification 688,982 is referred to.
