Abstract: A vehicle has a crash detection device for detecting a crash that introduces a force acting in an effective direction into the vehicle. An acceleration device directly or indirectly cooperates with the crash detection device to absolutely accelerate at least one partial mass of the vehicle against the effective direction in which the force is introduced in case of a crash.

Abstract: In an arrangement for strengthening the road grip for a vehicle, particularly for a passenger car, air can be sucked from a vacuum chamber arranged under the vehicle and closed off with respect to the ambient atmosphere. As a result, a vacuum can be generated in a vacuum chamber arranged in a braking plate, and the latter can be changed from an inoperative position away from the ground into a operative position close to the ground, as a result of the generated vacuum.

Abstract: To reduce degradation of a solid polymer fuel cell during startup and shutdown, a selectively conducting component is incorporated in electrical series with the anode components in the fuel cell. The component is characterized by a low electrical resistance in the presence of hydrogen or fuel and a high resistance in the presence of air. High cathode potentials can be prevented by integrating such a component into the fuel cell. A suitable selectively conducting component can comprise a layer of selectively conducting material, such as a metal oxide.

Abstract: The invention relates to a seat carrier arrangement for a vehicle seat (48) of a utility vehicle, especially a bus, said arrangement comprising a seat carrier (36) supported towards the rear on an energy-absorbing deformation element (52). The seat carrier (36) is embodied as a carrier part of a vehicle structure (10) on the front end of the utility vehicle. The invention also relates to a construction for a utility vehicle, especially a bus, comprising a vehicle structure (10) on the front end, with an upper and a lower absorber plane (12, 14). The invention also relates to at least one front axial bridge (58) of a base frame or a substructure (18) in the region of a front axle formed as a longitudinal deformation element.

Abstract: An influencing device for influencing an active chassis that includes a plurality of controllable spring or damper units of a vehicle is provided. The influencing device includes a roadway sensor that produces sensor data relating to a roadway located in front of the vehicle in a direction of travel, the sensor data being used to acquire a roadway profile. The influencing device also includes a pilot control unit that determines, as a function of the acquired roadway profile, a pilot control variable that is used to adapt the setting of the spring or damper units to the acquired roadway profile. An input signal for a vehicle body control system, which is used to control the position of the vehicle body, is calculated on the basis of the pilot control variable.

Abstract: In a valve drive device, especially for an internal combustion engine including a camshaft with a cam element which is axially movably supported on the camshaft but in a rotationally fixed manner, the cam element includes a gate structure and an actuation device is provided with at least one shift element for engagement with the gate arrangement for axially displacing the cam element and the shift element has a rotationally asymmetrical basic shape in order to follow the gate structure when placed in engagement therewith.

Abstract: The invention relates to bipolar plates for fuel cell systems. According to the invention, the component sheets of a bipolar plate (1) are formed for a welded joint (4, 5), such that between the profile regions (6) of the channel ducts (2), only small local surfaces remain as welding zones (10). The above is achieved by means of a corresponding shape of the profile molding (8, 9) of the component sheets. As a result of said reduction of the welding zones to small regions of the total surface, a larger proportion of the area is available for the channels (2), in other words, the channel cross-section and hence the coolant flow can be increased. At the same time the structure for the use of gas diffusion layers made from non-wovens, textiles or paper can be optimized.

At least one indication surface element (3) which occupies a part of the friction surface (2?) and differs from at least one of the components friction surface (2?) and anti-abrasion layer (1) of the friction disc (2) in at least one of the features coloring and texture is provided between the anti-abrasion layer (1) and the friction disc (2). Compositions of the anti-abrasion layer (1) of the friction disc (2).

Abstract: Method for producing an SMC multi-layer component in a production process. The component has a sandwich structure. At least one foam material layer (3) is embedded between two SMC cover layers (2, 2?). An insert layer arrangement comprising at least one first and one second SMC semifinished product cover layer (2, 2?) is positioned in a press mold comprising a punch (1) and a die (1?). A first and a second SMC semifinished product cover layers (2, 2?) are shaped into two SMC cover layers (2, 2?) by applying pressure to the layer arrangement. Curing of the first and the second SMC semifinished product cover layers (2, 2?) is initiated. The punch (1) and the die (1?) are moved away from each other, until the distance provided therebetween corresponds to a thickness of the SMC multi-layer component to be produced. A foaming process of a material (3?) that can be foamed, which is provided between the two SMC cover layers (2, 2?) is initiated, producing the foam material layer (3).

Abstract: In a gear shift device and a method for operating a manual gearshift device of a motor vehicle including a control unit which, in a gear shift mode is adapted to resolve a recognized tooth butt condition of a gear shift device which is to be engaged positively by a starting clutch, the control unit is adapted to select a starting mode for resolving the tooth butt condition by setting a startup readiness parameter which determines a startup readiness condition as established before the tooth butt condition is resolved for initiating clutch engagement and thereby resolving the tooth butt condition and, at the same time, starting movement of the vehicle.

Abstract: A seal arrangement in a fuel cell device seals against leaks in a mechanical joint between two components which convey a liquid and/or a gaseous process medium 3 in a media chamber of the fuel cell device. The seal arrangement has a first sealing member which extends around the media chamber in an installed state, and is in active connection with the components. A second, surrounding sealing member is arranged facing away from the media relative to the first sealing member and is formed of a different material from the first sealing member and/or has a different geometry.
