Support structure i.e. bottom structure, for land vehicle, has cross beam mechanism including arch braces that are connected with supports, respectively, where supports exhibit curvature

摘要

The structure (10) has a frame (76) including two supports (12, 14), where one of the supports is arranged at a distance from another support. A cross beam mechanism (30) connects the former support with the latter support and includes arch braces (52, 54) that are connected with the supports, respectively, where the supports exhibit a curvature. One of the arch braces is convexly curved away from the other arch brace, where the arch braces are mirror-symmetrically arranged to each other and made of an elastic material. The supports and the arch braces are made of a metallic material or a fiber-reinforced material.
