摘要:
Lumbar support and control device of a lumbar support and method for controlling a lumbar support of a motor vehicle. An electric control device is provided for a lumbar support which has a drive coupled mechanically to an adjusting mechanism for setting the seat contour of the lumbar support. The control device has at least one computer unit which controls a massaging movement of the lumbar support whereby the massaging movement is characterized through several predefinable ideal speeds. Several ideal speeds for one or more adjusting directions of the lumbar support are controllable through the computer unit. For control by the ideal speeds a drive moment of the drive is adapted to an actual load of the drive so that the massaging movement can be controlled substantially independent of the actual time-changeable or locally variable load. The drive moment is consequently changeable through the control device.

摘要:
A method for controlling a vehicle seat adjuster in an adjusting path having a first mechanical stop and a second mechanical stop. A user sets an adjustment position of the adjuster inside the adjusting path. A protective stop is also automatically set in the adjusting path in the vicinity of the mechanical stops or another mechanical block blocking the adjusting path. The protective stop causes the adjusting motion to be reduced or stopped upon reaching of the protective stop. This helps produce a smooth braking of the vehicle seat and reduces the mechanical strain on the mechanical stops. The protective stop may be corrected with an updated protective stop. The updated protective stop is maintained despite any user action if a condition dependent on the adjusting motion of the adjuster is fulfilled. Learning regions within the adjusting path are provided to allow the setting of updated protective stops within the learning regions.

In order to reliably detect a jamming situation, in particular in a seat adjusting means, provision is made for a total loading exerted by the drive during a start phase to be determined and for this to be fixed as the basic loading. The existence or non-existence of a jamming situation is finally determined during a monitoring phase by comparing the basic loading and the total loading that varies during operation of the adjusting apparatus.

The invention concerns a drive unit for a tracked vehicle with a first and a second electric generator (6, 8) and with a first and a second internal combustion engine (10, 12), such that one generator (6, 8) can be driven respectively by one combustion engine (10, 12), and with electric drive motors (14, 16, 18, 20) for driving a right-hand and a left-hand drive track (4, 2). According to the invention it is proposed that the elements of the drive unit are linked in such manner that the right-hand drive track (4) is associated with first and second right-hand electric drive motors (14, 16), the left-hand drive track (2) is associated with first and second left-hand electric drive motors (18, 20), the two first drive motors (14, 18) being fed by the first generator (6) and the two second drive motors (16, 20) being fed by the second generator (8). Due to the wiring of the energy paths according to the invention, very great operational security is achieved even when the drive unit is partially damaged.

The invention relates to a coupling device for connecting line devices, preferably quick connector, having a coupling housing comprising a connecting device that can be connected to an end section of a line device or of a second connecting device, and a valve body which can be transferred from a closed position to an open position when the end section of the line device or of the second connecting device is brought together with the coupling housing. The valve body can be actuated by means of a force deflecting device by bringing the end section of the line device or of the second connecting device together with the coupling housing.
