Abstract: A self-supporting underframe for a vehicle, the vehicle, and a production method thereof. The underframe has two elongate monocoques arranged parallel and spaced apart from each other and at least 50% closed on at least four sides, wherein the monocoques each have a single-part, trough-like element having at least one lower base and two side walls extending upwards from the base. At least one cover element closes the trough-like elements over at least 50% of the longitudinal extent of the particular trough-like element. The at least one cover element of each of the two monocoques in each case includes at least one cross-strut cover element, and the cross-strut cover elements of the two monocoques are designed as a common, single-part cross-strut cover element spanning an intermediate space located between the trough-like elements of the monocoques. The cover elements are fixedly connected to the side walls of the monocoques.

Abstract: A refrigerating device for holding food or drinks or other objects fitted with a front cover for opening and closing is arranged between the back rests of two seats spaced relative to each other in a vehicle and may be covered by an arm rest which may be folded up against the front wall of the refrigerating device, thereby optimizing the utilization of space in the vehicle.

Abstract: An injection die casting apparatus, especially for making molded articles especially of thermoplast-structural foam, with at least two closing units arranged adjacent to each other and provided with molds and mold chucking plates, and also equipped with an injection unit comprising an extruder, a pertaining charging hopper, a deflecting head and a hydraulic accumulator. The upper surfaces of the closing units have centrally arranged therein injection openings, and the injection unit is pivotable about a vertical axis and tiltable about a horizontal axis.
