Abstract: A holder for a controller housing of a central airbag unit is arranged on a central tunnel of the vehicle and fixed using fastening bolts by union nuts. A blank paint-free contact area is created around the fastening bolts by the union nuts being mounted on the fastening screws before a painting process. After a painting process, the union nuts are removed from the screws and the controller housing is mounted on the contact areas and secured by the union nuts.

Abstract: A transmission, in particular a dual clutch transmission, has a plurality of transmission shafts and a fastening apparatus for at least one fixed gear on one of the transmission shafts. The fixed gear is held axially on the transmission shaft by way of a fastening nut. The fixed gear is formed with a recess around the transmission shaft in a region that lies radially below the gear toothing system. A fastening sleeve is positioned in the recess between the fixed gear and the transmission shaft in a section which adjoins a fastening nut. During the clamping of the fastening nut, the latter bears against the fastening sleeve. As a result, the transmission of micromovements to the fastening nut is minimized or prevented, with the result that loosening of the fastening nut does not take place during the operation of the transmission.

Abstract: A shifting device for an automatic transmission of a motor vehicle with a gear-shift lever, which can be moved in an automatic shift track to select gear-shift positions; with a locking mechanism for blocking the adjusting movements of the gear-shift lever into at least one gear-shift position and/or out of at least one gear-shift position; and with a release button arranged on the gear-shift lever to release the blocking action of the locking mechanism. An increased level of functional reliability can be achieved by establishing a drive connection between the release button and two blocking elements, which are arranged redundantly on the gear-shift lever with the freedom to move up and down, that an actuation of the release button produces a synchronous stroke of the two blocking elements, where each of the blocking elements cooperates with an arresting gate comprising gate sections assigned to the gear-shift positions.

Abstract: An adjustable vehicle seat (1) has an inclinable seat part (2) and an inclinable backrest (3) mounted to the seat part (2). Front and rear areas of the seat part (2) are mounted pivotably in bearings (7, 5) at positions adjacent to remote sides of the seat part (2). The bearings (7, 5) also are mounted pivotably in the vehicle floor or rails (11). The lengths of the front bearings (7) can be changed for changing an inclination of the seat part (2). A backrest adjusting motor adjusts inclination of the backrest (3) to compensate for changes in the inclination of the seat part (2).

Abstract: A cockpit cross member (1,1?,1?) for a motor vehicle, has a basic member (2) and at least one fastening bracket (3) for connecting the cockpit cross member to the vehicle body (4). The basic member (2) is designed as a light-metal cast structure, and an adjusting element (18, 19, 20, 21, 22, 23) is provided between the basic member (2) and the fastening bracket (3) to at least partially absorb the force exerted on the cockpit cross member in the event of the motor vehicle crashing.

Abstract: A vehicle has at least one electric machine that can be operated as a generator, an electrical energy accumulator and a control unit for controlling the at least one electric machine and the electrical energy accumulator. The control unit operates so that in a recovery phase the vehicle can be decelerated by the generator load of the electric machine operated as a generator (2:a) and the resulting electrical energy (1:E) can be stored in the electrical energy accumulator. The control unit is configured so that the at least one electric machine operated as a generator in a recovery phase is operated by said control unit in a chronologically unlimited fashion with a predefinable overload (2?:a, 2?:a, 2??:a).

Abstract: A vehicle body for a motor vehicle has a vehicle rear end with body inner side parts spaced apart from one another and delimiting an engine bay. An assembly support runs in the vehicle transverse direction between the two body-side side parts. The assembly support is formed as a light metal forged part. Weight-optimized stiffening of the vehicle rear end can be obtained in this way.

Abstract: Inlet openings at the frontal region of a vehicle have actuable transversely oriented pivoting lamellae disposed behind them. The lamellae guide an air flow to a vehicle radiator in a targeted manner. The pivoting lamellae are connected to an actuating device with control linkages that are articulated to one another via deflection levers for an upper and a lower lamella unit. The upper pivoting lamellae are adjusted at an angle which is different than the lower pivoting lamellae. The upper pivoting lamellae can be set in each case as a unit jointly with the lower pivoting lamellae as a further unit.
