  • Motor Vehicle Having a System for Feeding Fluid into Another Medium, Particularly for Feeding a Reducing Agent into the Exhaust Gas of an Internal Combustion Engine
    Publication number: 20110179772
    Abstract: In a system for feeding fluid into an exhaust gas after-treatment system, during operation fluid is fed via a feed line of the dispensing unit from a main container and is partially returned via a return line to the main container. A diaphragm pressure container is provided on the feed line downstream of a pump and a non-return valve toward the dispensing unit. During operation of the pump, the diaphragm pressure container is filled with fluid. The diaphragm pressure container is emptied as soon as the pump stops operating. In this way, the dispensing unit is cooled even after the operation of the system has ended, thereby protecting electronic components of the same from overheating.

  • Motor vehicle comprising an occupant restraint device
    Patent number: 7983819
    Abstract: A motor vehicle with an occupant restraint device, including a control device which produces a triggering signal when a predefined hazard signal is generated as a function of signals of a safety sensor system, and, accordingly, the occupant restraint vehicle acts on a vehicle occupant by at least one impact cushion. The control device generates the hazard signal at least as a function of vehicle acceleration signals and a belt state signal representing the activation or deactivation of a seat belt, deactivating the occupant restraint device at least for a certain period of time and/or activating the occupant restraint device at reduced power if the seat belt is identified as having been deactivated and vehicle acceleration signals are assigned to a critical forward displacement of the occupant if the seat belt is deactivated.

  • Method and device for recognizing tiredness
    Patent number: 7978086
    Abstract: In a method and in a device for detecting when the driver of a motor vehicle becomes tired, the tiredness is determined as a function of a detected steering inactivity phase and a subsequent steering action. In this context, the steering inactivity phase is logically combined with the steering action, and the logic combination is stored at various times. The logic combination is stored with an assigned weighting factor, and the weighting factor is determined as a function of a classification of a steering situation.

  • BRAKE DISK HAVING A BRAKE DISK POT
    Publication number: 20110162926
    Abstract: The invention relates to a brake disc having a brake disc pot (42) and a friction ring (10) which is positively connected to the brake disc pot via toothing (50). The friction ring (10) comprises two friction ring halves (12, 14), wherein the toothing extends across only one of the friction ring halves. In this manner it is possible to mount through-passages (30) axially adjacent to the toothing running around the friction ring half on the interior circumference of the friction ring, said passages connecting the interior circumference of the friction ring to an interior ventilation arrangement of the friction ring. In this manner both a good force transmission and a stable positive connection is ensured between the friction ring and the brake disc pot, as is an efficient cooling by means of an interior ventilation of the friction ring.

  • ILLUMINATION CHAMBER FOR HARDENING RADIATION-CUREABLE COATINGS
    Publication number: 20110162226
    Abstract: The invention relates to an exposure chamber (10) for hardening radiation-curable coatings on components (14) having surfaces which are oriented in different directions. The invention also relates to an exposure chamber (10) for hardening motor vehicle bodies coated with UV-paints by means of UV-lamps. According to the invention, at least one reflector (20) is arranged in an inner chamber (18) of the exposure chamber (10). Said type of reflector (20) is preferably spherical or alternatively can be pivoted about three spatial axes in a cardanic manner such that, owing to this reflector (20), shadow zones of the vehicle body which are normally exposed inadequately can be uniformly illuminated. The invention further relates to a hardening system (42, 42?) for motor vehicle bodies which comprises said type of exposure chamber.
