Motor vehicle chassis
First Claim
1. In a chassis for a motor vehicle comprising front and rear wheels, and suspension means and damping means for said wheels, said chassis comprising a central beam, having a length, and a plurality of support means attached respectively to opposite ends of said central beam and extending substantially perpendicular to a longitudinal direction of said central beam, said support means being adapted to carry said suspension means, the improvement wherein said chassis further comprises:
- at least two elongated hollow beams spaced from and attached to said central beam and extending substantially parallel to said central beam, wherein said at least two elongated hollow beams are attached to said plurality of support means, and wherein opposite ends of each of said at least two elongated hollow beams are deformable and extend beyond said opposite ends of said central beam at a front and a rear of said chassis;
wherein said at least two elongated hollow beams extend along either side of said central beam;
wherein said opposite ends of said at least two elongated hollow beams extend into said support means and beyond;
wherein each of said opposite ends of said at least two elongated hollow beams comprises deformation initiating means in the longitudinal direction; and
wherein said central beam has means for housing batteries.
