Abstract: Two low-voltage energy storage devices (B1 and B2) are provided in an arrangement that ensures, on the one hand, a high start power in the vehicle electrical system, resulting from being connected to a higher-level voltage, for a starter generator (SG) that is coupled to an internal combustion engine. The arrangement additionally ensures, on the other hand, full compatibility with low-voltage vehicle electrical system consumers (VB). The arrangement allows the two low-voltage energy storage devices (B1 and B2), either separately or when connected in parallel, to supply the vehicle electrical system consumers (VB) with a low voltage. In addition, the arrangement allows the two low-voltage energy storage devices (B1 and B2), when connected in series, to provide the high start power with increased voltage and correspondingly reduced current intensity at least for a cold start of the starter generator (SG).

Abstract: In order to reduce the battery load, a second elevated onboard electrical system voltage is provided at least for high-current consuming components. The voltage is derived from the battery voltage via a step-up switching regulator (SUSR) or is supplied by a starter-generator (SG) via a converter (CONV) in the generator mode of the starter-generator, which is coupled with an internal combustion engine (ICE) of the vehicle. The step-up switching regulator is used for battery supply of a start capacitor (CAP) and the converter is used for triggering of the starter-generator to start the internal combustion engine.

Abstract: An adaptable frame carrier with triaxial freedom of movement for couches and seats, in which the freedom of movement is achieved in the X-, Y- and Z-direction by a system of elements which can be moved relative to one another and are spring loaded, a connecting element making the moveability between the X-, Y- and Z-direction interdependent. The frame carrier having at least one dome-shaped rolling body (3, 8) which rolls along a pressure-resistant rolling plate (2) in the X- and Y-direction, and two cylinders (6, 7) which slide one into the other and are supported against each other in the Z-direction by a compression spring (4). One of the cylinders (7) which slide one into the other being connected in a spring-loaded and hinged manner to the frame (18) of the couch or seat via a frame connection plate (13).
