An underbody panel for a motor vehicle is composed of a lightweight sandwich material and is configured as a single part with at least one continuous folding connection (12) that is arranged between first and second portions of the underbody panel (14). The first and second portions can be folded together via the folding connection (12) and, in the folded state, are substantially parallel to each other to reduce a size of the underbody panel during transport and storage. Additionally, the underbody panel is gap-free when installed on a motor vehicle.

A longitudinal member arrangement of a body of a motor vehicle is designed such that, in the event of a collision of the motor vehicle, the longitudinal member arrangement progressively fails, absorbing collision energy, with a first longitudinal member element which is formed from a fiber composite, and with a second longitudinal member element which is formed from a fiber composite and is arranged behind the first longitudinal member element. The first longitudinal member element and the second longitudinal member element are connected to each other by a connecting element. The longitudinal member arrangement is designed such that, in the event of the collision of the motor vehicle, the second longitudinal member element begins to fail after the first longitudinal member element has failed.

This automobile member has a closed cross section including joint portions in which edge portions of two side walls of an inner panel are joined with edge portions of two side walls of an outer panel, in which in a first region, a first region outer height ho.sub.1 and a first region inner height hi.sub.1 have a constant value and the difference between the first region outer height ho.sub.1 and the first region inner height hi.sub.1 is smaller than the difference between a second region outer height ho.sub.2 and a second region inner height hi.sub.2; in a second region, the second region outer height ho.sub.2 has a value which is larger than the second region inner height hi.sub.2 and constant, or the second region outer height ho.sub.2 has a value which is smaller than the second region inner height hi.sub.2 and constant; in a first transition region, a first transition region outer height ho.sub.1?2 is continuously varied between the first region outer height ho.sub.1 and the second region outer height ho.sub.2, and a first transition region inner height hi.sub.1?2 is continuously varied between the first region inner height hi.sub.1 and the second region inner height hi.sub.2.

A vehicle body structure includes a front side member, a body attachment structure and an off-center impact structure. The front side member defines a hollow interior, an outboard wall and an inboard wall. The body attachment structure is attached to the outboard wall of the front side member. The off-center impact structure has a first end portion, a second end portion and a main section extending from the first end portion to the second end portion. The first end portion extends through an outboard forward opening and into the hollow interior of the front side member and is rigidly connected to the front side member forward of the body attachment structure. The second end portion is attached to the front side member at a location rearward of the body attachment structure with the main section extending outboard of the body attachment structure.

A rear structure of a vehicle includes: a rear lamp (6) provided at rear (1R) of the vehicle; and a rectifying member (3) extending from a center in a vehicle width direction to an outer side in a right and left direction. The rectifying member (3) includes an outer part (32) positioned on an outside in the vehicle width direction and a central part (31) positioned on the center in the vehicle width direction. The outer part (32) partitions the rear lamp (6) in a vertical direction of the vehicle, and an upper surface of the central part (31) extends further toward an upper side of the vehicle than the rear lamp (6) in the vehicle width direction.

An electrically powered motor vehicle includes a main frame, a front axle assembly, and a rear axle assembly. The main frame includes a front frame subassembly, a floor-panel subassembly, a rear frame subassembly, and a top frame subassembly. Each of these frame subassemblies includes a lattice structure including steel box-section elements, preferably high-strength steel elements. Each of the frame subassemblies is prearranged for being pre-assembled separately and then subsequently assembled together with the other subassemblies to constitute the main frame. The structure is such as to afford high flexibility of production, and presents at the same time considerable safety characteristics, thanks to a high capacity of absorption of impact energy. In one embodiment designed for transport of goods, the motor vehicle is equipped with a transporting body having a hollow-walled body made of plastic material, filled with foamed plastic material, preferably obtained with the rotational-moulding technique.

A reversible load floor is provided for a motor vehicle. The reversible load floor includes a body having a first user surface and a second user surface wherein the first user surface is opposed to the second user surface.

A tunnel reinforcing member is attached to a front floor tunnel. Second upper wall and second side walls of the tunnel reinforcing member are connected to a first upper wall and first side walls of the front floor tunnel, respectively, such that spaces are formed between second edge portions of the tunnel reinforcing member and first edge portions of the front floor tunnel. A rear portion of the first upper wall of the front floor tunnel faces a lower wall of a cross member with a kick-up part in between. A rear portion of the second upper wall of the tunnel reinforcing member inclines upwards and rearwards so as to be separated apart from the first upper wall of the front floor tunnel and faces a section reinforcing member fixed to the cross member with the kick-up part in between.

A vehicle frame is disclosed. The vehicle frame may include an extruded metal hollow columnar beam defining in cross section, four interconnected arms, each having nine sidewalls and a bulbous free end, arranged to form a cross with thirty-six corners, and configured to dissipate axial compression loads via deformation of the thirty-six sidewalls and the thirty-six corners.

A removable panel system for easily and efficiently varying the configuration of a cabin on a vehicle. The removable panel system generally includes a vehicle having a cab defined by a frame. Different panels may be selectively and removably connected to the frame to form various different cab configurations to suit the different needs of different jobs or operators. A roof panel may be removably connected to the frame to form a roof of the cab. A rear window extension may extend from the roof panel to form the rear window of the cab. A door receiver panel and/or door panel may be removably connected to the frame to form one or more doors of the cab. A windshield panel may be removably connected to the frame to form a windshield for the cab. All panels are adapted to be easily and efficiently interchanged without undue effort from the operator.
