  • Patent number: 5092655
    Abstract: The seat cushion of a vehicle seat, especially of an air passenger seat, lies on a cushion support that is supported by parts of the seat frame. This cushion support lies lower in the area which supports the sitting part of the seat than in the area situated in front of this. The cushion support is designed as a shell (6), which forms a depression (13,14) in the region which supports the sitting part of the seat, said depression being matched to the shape of the human seat.

  • Patent number: 5090384
    Abstract: A device for electronically controlling adjusting devices in an internal combustion engine in which the adjusting devices can be controlled, by comparing differentiated engine speed signals with predetermined threshold values in such a way that shuddering oscillations of the internal combustion engine are counteracted. The engine speed variable (n) is derived by means of a sensor (10) which provides a plurality of pulses per revolution of the engine crankshaft or camshaft. A first divider (14) divides the pulses from the sensor (10) by a fixed ratio. The output of the divider (14) is further divided in a divider arrangement which provides different divider ratios in dependence upon engine speed, the divider ratios being chosen so that measurement at engine speed is made over a complete combustion period of the engine, or a multiple thereof.

  • Patent number: 4993389
    Abstract: A device for the electronically controlled influencing of actuating devices of an internal combustion engine is proposed in which actuating devices can be influenced by comparing differentiated sensor signals with predeterminable threshold values. The actuating devices are directly accessed without a detour via any regulating devices. The system corresponding to the method thus becomes very simple and inexpensive in its construction. Control-loop-related oscillations are avoided by the direct influencing of the actuating device.

  • Patent number: 4793308
    Abstract: An emergency control device for a diesel internal combustion engine with electronically controlled fuel proportioning, which enables an optimal emergency driving operation in case of a defect of the transmitter or transmitters for the actual value of fuel volume. In the event of an error, the mechanism determining the desired value of fuel volume during normal operation, and the fuel volume regulating device, are separated from the fuel proportioning device and the latter is controlled by a special emergency driving signal. An error in the transmitters for the actual value of fuel volume is recognized in that this signal does not fall in the allowable area for the actual value of fuel volume. A first signal, which, together with a second signal, gives the emergency driving signal, is formed from the speed and the accelerator position. The second signal consists substantially of the differentiated speed signal.
