Abstract: A filter material for air filtration in a filter element, including an inflow-side pre-filter layer, an active carbon layer, and a composite layer which is in the form of a fine filter layer including nanofibers. The pre-filter layer, the active carbon layer and the composite layer are connected to one another in materially bonded fashion. The composite layer includes at least one top layer, a nanofiber layer and a carrier layer.

Abstract: A filter material for air filtration in a filter element. The filter material includes a prefilter layer on an inflow side, an activated carbon layer, and a composite layer. The composite layer is formed with at least one membrane layer. The prefilter layer, the activated carbon layer and the composite layer are materially bonded to each other.

Abstract: A motor vehicle steering mechanism is provided and includes a steering wheel fixedly connected to a steering column, a steering pinion meshing with a rack, a planetary gear system connected to the steering column and the steering pinion, wherein during a normal trouble-free driving operation the housing of the gear system is freely rotatable; an angle sensor detects the position of the steering column and/or steering wheel and generates a signal representative thereof, wherein a first drive applies torque directly to the steering column, and a second drive acts on the steering pinion or rack. The signal from the angle sensor is an input signal for an electronic control system that controls the second drive. A torque adjuster controls the first drive such that a hand torque corresponding to a driving situation is Produced for achieving a defined driving sensation for the driver on the steering wheel.
