  • Driver's seat with weight sensor
    Publication number: 20060028007
    Abstract: A driver's seat comprises a weight-sensing mechanism for a motor vehicle. In order to optimize a vehicle seat of the generic type in such a way that very reliable weight measurement is obtained for the indicated purpose, the seat is provided with at least one seat tub (1) into which at least one additional planar element (10) is inserted while at least one weight sensor (20) is disposed between the seat tub (1) and the planar element (10).

  • Electric circuit provided with a plug-in connector, in particular a control device for motor vehicles
    Patent number: 6302707
    Abstract: An electric circuit configuration includes an electric circuit, with a printed circuit board provided in a housing. The printed circuit board carries circuit elements and defines a printed circuit board plane. A plug-in connector element is provided at the housing and has a plurality of contact elements disposed in at least one first row. The plug-in connector element has short-circuit interrupters disposed at respective interrupter positions at the rear wall The short-circuit interrupters are configured as electrically non-conductive pins integrally formed with the rear wall and are disposed in a second row. None of the contact elements are, none of the contact elements are disposed in the second row. The second row is disposed beneath the at least one first row and is closer to the printed circuit board plane than the at least one first row. Thus the number of plug contact elements can be increased considerably without increasing the overall height of the control device.
