Vehicle body frame structure
First Claim
1. A body frame structure composed of members extruded from a light alloy, for forming a skeletal structure of a vehicle, comprising a plurality of hollow frame members, each and every one of said hollow frame members formed from an extruded hollow member of light metal and having an overall polygonal continuous closed-loop configuration, said hollow frame members of polygonal continuous closed-loop configuration being joined together along adjacent sides thereof to form said skeletal structure, wherein each of said hollow frame members is comprised of at least two hollow frame pieces joined together by means of a split muff coupling.

Abstract
A vehicle body frame structure is comprised of plurality of loop-shaped members each formed by a hollow pieces extruded from a light alloy. Each loop-shaped member is polygonal in cross section. The vehicle body frame structure is partly formed by a plurality of such loop-shaped members joined sidewise together. Each loop-shaped member is comprised of at least two hollow extruded pieces joined together by a core coupling or a split muff coupling. Part of each loop-shaped member is stepped so that it can be joined with a companion loop-shaped member by mating the stepped portions of the two loop-shaped members one over the other.
