Abstract: A fuel cell system includes at least one fuel cell stack designed to react reactants for current generation, a cold start detection apparatus for detecting a cold start state of a fuel cell stack and a load which may be connected to the fuel cell stack 2. A control device is designed to connect the load when the fuel cell stack 2 is in the cold start state. The supply of the reactants for the fuel cell stack is conformed to connection of the load, and the control device is designed with software and/or circuitry so as to vary the connected load in one or more step load changes in response to detection of the cold start state of the fuel cell stack.

Abstract: A receptacle device that is attachable to a motor vehicle includes a receiving tube into which an insertion tube of an adapter having a trailer ball can be inserted. The insertion tube is held in the receptacle tube with the help of a splint. In order to eliminate play between the insertion tube and the splint, the insertion tube is pressed against the splint by a pressure piece. A first segment of the pressure piece fits the inner diameter of the receiving tube, so that the pressure piece can be held by said receiving tube, while a second segment engages precisely in the insertion tube in order to be held thereby.

Abstract: A vehicle occupant safety system having an airbag prevents an excessive force from acting upon the thorax of an occupant who has fastened the seat belt, in the event of an impact. The vehicle occupant safety system comprises an airbag, a sensor device for sensing at least one situation parameter and a control device for controlling the inflation and/or deflation and/or unfolding and/or positioning of the airbag in dependence of the at least one situation parameter. The unfolding, position or shape of the airbag and/or distribution of pressure within the airbag at the end of the filling phase, is directly or indirectly controlled in a targeted manner by a control device based on the at least one situation parameter. A modification of the shape of the airbag in the thorax region can be obtained in particular by a releasable constriction.

Abstract: An exhaust gas aftertreatment installment and associated exhaust gas aftertreatment method utilizes a nitrogen oxide storage catalytic converter and an SCR catalytic converter. A particulate filter is provided upstream of the nitrogen oxide storage catalytic converter or between the latter and the SCR catalytic converter or downstream of the SCR catalytic converter. The time of regeneration operating phases of the nitrogen oxide storage catalytic converter can be determined as a function of the nitrogen oxide content of the exhaust gas downstream of the nitrogen oxide storage catalytic converter or of the SCR catalytic converter and/or as a function of the ammonia loading of the latter. Moreover, a desired ammonia generation quantity can be determined for a respective regeneration operating phase. The installation and method are adopted for use for motor vehicle internal combustion engines and other engines which are operated predominantly in lean-burn mode.

Abstract: The invention relates to a restraint system for a motor vehicle that is formed by one or several supporting structures, wherein the longitudinal extension of a supporting structure in the active state substantially exceeds the dimensions of the transverse extension and the supporting structure unfolds mainly in the direction of its longitudinal extension. So as to improve the restraint system such that the variables of the restraint system are adapted to the respective load, it is suggested that, during unfolding, the supporting structure (7, 8, 9), when impacting upon an obstacle (5), does not have the same stability as when it is completely unfolded, and/or does not reach the final volume or the final extension.

Abstract: A heat exchanger unit for an electrochemical energy accumulator, comprising flow channels, through which a temperature control medium flows. Ends of the flow channels are provided with flow distributor channels, which supply the flow channels, and/or return flow collection channels, and which collect the medium. A flow distributor is connected upstream of the flow distributor channels and a return flow collector is connected downstream of the return flow collection channels. The flow distributor and the return flow collector are separated from, and lie opposite, each other. A supply opening is located centrally on one of the lateral surfaces of the flow distributor and a drain opening is located centrally, on one of the lateral surfaces of the return flow collector.
