Abstract: A motor vehicle has at least one vehicle seat (3) and a trim part (1) that extends in the vehicle transverse direction (FQ) behind the vehicle seat (3). A cross member (2) is arranged below and/or behind the trim part (1). The trim part (1) carries a protective element (11) on an end face (6) of the trim part (1) that faces the vehicle seat (3) to protect the trim part (1) from damage caused by contact with the vehicle seat (3).

Abstract: A single-part or multi-part stiffening device for increasing the torsional stiffness of a motor vehicle embodied as a cabriolet, has at least one stiffening element which is connected at one side to a rear side of a rollover protection device and at the other side to a base of a covering shelf of the motor vehicle.

Abstract: A rollover protection device is disposed behind the vehicle seats of a motor vehicle, in particular a convertible with a convertible top, and has at least one rollover protection cassette containing a rollbar. It is important here that the at least one rollover protection cassette or a housing of the same is a supporting component of a stiffening support which is of multi-part construction and extends in the transverse direction of the vehicle.

Abstract: A vehicle air guiding system in a rear area of the vehicle has a central air guiding element displaceable between a moved-in inoperative position into a moved-out operative position. Lateral air guiding elements, which are displaceable together with the central air guiding element, are telescopically displaceable relative to the central air guiding element while enlarging the transverse dimension of the air guiding system transversely to vehicle longitudinal direction from an also moved-in inoperative position into an also moved-out operative position. In the inoperative position, the lateral air guiding elements are pushed over the central air guiding element so that they rest against one another by way of the end sections and completely cover or envelop the central air guiding element.

Abstract: A frame structure suited for motor vehicle superstructures includes first and second beams conjoined to form a “T” and a joint which is present between the two beams. To ensure that this frame structure is of optimal weight and stiffness, the first and second beams of the frame structure are made of tubes with elliptical cross sections having secondary axes which run parallel to one another. A joint is present at the second beam and is realized as an expansion of the diameter of the first beam. When viewed lengthwise along the second beam, the joint has a defined length from the outermost edge of the first beam spanning toward the second beam.

Abstract: A MacPherson strut tower made in one piece for a motor vehicle, especially an automobile, is permanently connected with at least one adjoining side member of the body structure. The MacPherson strut tower, formed by a hollow body produced by the internal high-pressure shaping method, results in a significant increase in torsional stiffness of the body structure since the two side members and the MacPherson strut tower are assembled to form a three-dimensional supporting structure with continuous closed hollow member sections.

Abstract: A center tunnel for a vehicle, especially a motor vehicle, has a section shape that is open at the bottom and has sections in the form of hollow members that are directed lengthwise, at least areawise. A center tunnel that has a simple design and can be manufactured economically, and which is torsionally rigid and can accept high forces, is formed by a double-walled hollow body manufactured by the internal high-pressure shaping method, viewed in cross section, with spaced wall sections of the hollow body being brought together areawise.

Abstract: A floor assembly for a passenger car includes a double-walled floor provided with local reinforcements between laterally external side members and a center tunnel. To reduce the cost of manufacturing and assembly of the floor assembly, the double-walled floor on the driver and passenger sides is formed by at least one hollow member manufactured by the internal high-pressure shaping method. The respective hollow members abut the associated laterally external side member and the center tunnel and are permanently connected therewith. The reinforcements are formed by wall sections of the respective hollow body that are adjacent to one another areawise and are opposite one another.

Abstract: A support of a body structure of a vehicle is formed by hydraulic expansion of hollow blanks. In order to achieve that the support is adapted to the locally occurring loads, it is provided that, at least along a partial area of its longitudinal course, the support is composed of at least two form-lockingly connected, hydraulically expanded, mutually in parallel extending hollow profiles.

Abstract: A vehicle body for motor vehicles, particularly passenger cars, has supports and receiving devices for vehicle components. In order to provide a receiving device which can be manufactured at low cost and is easy to mount and by which high forces can be absorbed and introduced into the vehicle body, the receiving device is formed by an extruded profile part connected with the vehicle body.
