The invention relates to a body structure, in particular a floor structure, for a motor vehicle, comprising support components that form defined load paths for crash situations. According to the invention, at least some of the support components located in the region of at least one defined load path, in particular a head-on collision load path and/or a side collision load path and/or a rear collision load path, are formed by high-strength support components, preferably by fully through-hardened or at least partially through-hardened high-strength support components which are made of a hot-formed or shape-hardened sheet steel and which are directly or indirectly, preferably directly, connected to each other, in particular connected to one another non-positively and/or positively and/or by bonding.

Body structure, in particular floor structure, for a motor vehicle

The invention relates to a cross member assembly, in particular a floor cross member assembly and/or a footwell cross member assembly, on a vehicle body, having a cross member () which extends in the vehicle transverse direction and on which at least one longitudinal member (), to which force may be applied, in particular in a crash situation, and which essentially extends in the vehicle longitudinal direction, is supported by force in a defined longitudinal member supporting area (), the cross member assembly having at least one member component () which extends away from the cross member () diametrically opposed to the longitudinal member () to which force may be applied and/or which is connected in a member component connecting area. According to the invention, a defined, force-conducting load path profile (), which is designed to be elevated and/or recessed in relation to an adjacent surface area of the cross member (), is provided on the cross member () and extends from the longitudinal member supporting area () in the direction of or up to at least one member component () and forms a defined load path area on the cross member side.

Cross member assembly, in particular a floor cross member and/or a footwell cross member assembly, on a vehicle body, in particular on a motor vehicle body

The invention relates to a car body structure, especially a substructure, for a motor vehicle, with beam components that create defined load paths in collision situations. According to the invention, the beam components situated in the area of at least one defined load path&#x2014;especially a head-on collision load path and/or a side collision load path and/or a rear-end collision load path&#x2014;at least partially comprise high-strength beam components, preferably completely through-hardened or at least partially through-hardened high-strength beam components, made out of a hot-worked or press-hardened steel sheet, said beam components being joined to each other directly or indirectly, preferably directly, especially being joined to each other positively or non-positively and/or by bonding.
