Abstract: A radiator grille for a motor vehicle includes a basic support with a region for a marquee badge having an external contour that is, at least in regions, curved or oblique. A number of fins are held on the basic support, the number of fins are movable out of a closed position closing respective passage openings in the radiator grille into an open position uncovering the passage openings. In this case, at least one of the fins is displaceable in the direction of its longitudinal extent by bringing it from the closed position into the open position.
Abstract: A safety valve for a compressed gas reservoir has an exhaust duct that is connected to the compressed gas reservoir, and a sealing element, which is arranged to move within the exhaust duct, and selectively opens the exhaust duct to the outside depending on an operating phase. The exhaust duct has a greater cross-sectional area on the side facing away from the compressed gas reservoir than on the side facing the compressed reservoir, and a constriction on the side of the sealing element facing away from the compressed reservoir.

Abstract: A belt strap for a safety belt of a vehicle includes a belt interior located between two belt strap layers, to which belt interior a gas can be applied. A gas passage connecting at least two sections of the belt interior is provided between the at least two belt strap layers. The gas passage is secured at a first end in the region of an end fitting of the safety belt. The gas passage, which is designed as a flexible tube, is secured within the belt interior with at least a second end, which is located opposite the secured first end.
Abstract: In a method for adapting an electric control of a fuel injector with a nozzle needle, with which fuel is metered for injection into a combustion chamber of an internal combustion engine, wherein a momentary operating state of the internal combustion engine is monitored and the electric control is adapted in dependence thereon, the momentary operating state is monitored based on a pressure prevailing in the respective combustion chamber, wherein an actual work value of a cylinder is determined based on the measured pressure, the determined actual work value is compared with a target work value assigned to the momentary operating state, and the adaptation of the electric control of the respective fuel injector is carried out dependent on the target-actual comparison of the momentary work of the respective combustion chamber and the lift of the nozzle needle of the fuel injector is corrected dependent on the target—actual comparison.
Abstract: A seat belt for a vehicle includes a belt webbing with several belt webbing layers and, in a shoulder belt region and a lap belt region, at least one belt interior located between at least two belt webbing layers and to which a gas can be applied. The belt webbing is routed through an opening of a latch plate that can be inserted into a buckle, by means of which latch plate the belt webbing is, if the seat belt is fastened, deflected at a lower deflection point in a transitional region from the lap belt region to the shoulder belt region. A gas passage connecting at least two sections of the belt interior is provided at the lower deflection point between the at least two belt webbing layers. The gas passage is in the form of a tube that is flexible at least in the radial direction.
Abstract: In a method for operating a supercharged internal combustion engine of a motor vehicle, at the same time an internal exhaust gas recirculation and an external exhaust gas recirculation are carried out in an engine operating range with lean burn operation modes, wherein the exhaust gas recirculation rate of the internal and the external exhaust gas recirculation is increased with increasing load and/or speed of the internal combustion engine in the lean engine operating range and, at high engine speeds and loads, a homogenous mixture operation is carried out. The invention also reside in an internal combustion engine for performing the method.
Abstract: Systems and methods for more precisely detecting a position of objects detected in the surroundings of a vehicle with regard to a schematic top view of the vehicle are provided. A driver assistance device for a vehicle includes a sensor device for detecting an object in the surroundings of the vehicle and a display unit for visually representing the object detected by the sensor device with regard to a schematic top view of the vehicle. Ground coordinates of the object as position data can be detected using the sensor device. The ground coordinates are used by the display unit to position a symbol, which symbolizes the object in the top view, in the representation.

Abstract: A proton conducting copolymer electrolyte with competitive voltage versus current density characteristics and superior durability comprises a proton conducting hydrophilic domain comprising a sulfonated poly(phenylene) polymer, and a hydrophobic domain comprising a main chain comprising a plurality of bonded arylene groups wherein essentially all of the bonds in the main chain of the copolymer are carbon-carbon or, to a certain extent, carbon-sulfone bonds. More particularly, none of the bonds in the chains of the copolymer are ether bonds. Due to the absence of ether bonds, the copolymer electrolyte is less susceptible to degradation in solid polymer fuel cells.

Abstract: In a method for operating an air-compressing fuel-injection internal combustion engine having an exhaust gas post-treatment system with a particle filter and a nitrogen oxide reduction catalytic converter, a plurality of internal combustion engine operating settings are provided, each having respective predefined values for predefined internal combustion engine operating parameters. A heating operating setting is set when the internal combustion engine is warming up, while a basic operating setting is set in the warmed-up state. When the temperature in the exhaust gas system exceeds a predefinable first value, the heating operating setting is changed over to the basic operating setting. In the warmed-up state, at least one further (third) operating setting, with an exhaust gas recirculation rate that is reduced compared to the basic operating setting, is provided in addition to the basic operating setting.
