841,237. Motor vehicle frames. DAIMLERBENZ A.G. March 5, 1959 [March 11, 1958], No. 7746/59. Class 79(4). The ends of the longitudinal members 2 of the chassis of a motor vehicle are provided with constructional parts which start from the ends of the members and extend over the wheels in approximately the form of an arc, a series of structural elements being connected to the parts and having strengths of resistance to impact which decrease towards the end of the vehicle. If the vehicle receives an impact in the direction of the arrow 9, Fig. 1, a resilient beading 8, four deformable box-section members 7 an end wall or a radiator grill 6, supporting members 5 and extensions 3a to arcuate members 3 are deformed before any damage occurs to the vehicle chassis and interior 10. A similar construction with the members 5 arranged at a lower level is provided at the rear of the vehicle. The extensions 3a and members 5 are inclined towards the centre line of the vehicle. In Fig. 3, the extensions 3a are straight and connected at points 11 to struts 12 carrying deformable members 7 and a resilient beading 8 which may be provided with horns or a further resilient covering. The deformable members are affected first by collision. Fracture then occurs at 11 due to the leverage h1 and the extensions 3a are bent by the leverage h2. In a further construction, the parts 3 and their extensions 3a are made from sheet metal, serve as mudguards and are connected to the skirts enclosing the boot and engine space. |
