Abstract: A subassembly for the front and rear region of a motor vehicle, which comprises two longitudinal members to which a subframe designed as assembly carrier is attached by one end region of two elongate carrier parts. The members are together used for energy absorption in the case of a vehicle impact and are fixed by their ends, which project as far as a passenger compartment, with laterally spaced longitudinal members reinforcing the latter at the vehicle floor. After they have been fixed on the longitudinal members, the carrier parts extend freely with a portion oriented approximately in the longitudinal direction of the vehicle towards the passenger compartment and are guided with an obtuse-angled bend about a vertical axis towards the respective proximate longitudinal member and attached to the latter. Near to the bend, these carrier parts are connected in the longitudinally oriented portion by a subframe cross member.

Abstract: The invention relates to a closed hollow support which has stiffening sections in its interior. The stiffening sections are connected with the support section and with one another. The support sections, which form the outer surface of the hollow support, are welded together along longitudianl seams and at least one of them has holes which are suitable for guiding a welding tool, a screwdriver or a riveting tool used to connect the stiffening sections.
