Abstract: An adjustment device for a steering wheel may have a first shaft about which the steering wheel is pivotable. A rotary latch is rotationally fixed to the steering wheel by a rotary latch element. A second shaft is arranged in parallel with the first shaft. A coupling lever is arranged on the second shaft to interact with the rotary latch element. The coupling lever has a stop surface which, for the purpose of engagement, engages in at least one corresponding stop surface of the rotary latch element when the steering wheel, and thus also the rotary latch, is pivoted. At least one of the stop surfaces may have a chamfer via which the coupling lever can be displaced or is displaced out of the engagement with the rotary latch element when a predetermined force is applied to the steering wheel.

Abstract: Synthetic noises are generated to mask undesirable disturbing noises arising during the operation of a vehicle. The synthetic noise is generated from an unmodulated synthetic noise to adjust a desired sound characteristic by multiplication with at least one filter and/or amplifier which is dependent on a vehicle parameter. A pitch of all acoustic signals of which the modulated synthetic noise is composed is kept constant during an emission of the modulated synthetic noise. The unmodulated synthetic noise is designed as 1/f noise, and is pre-modulated by at least one static filter before being modulated by the at least one filter and/or amplifier which is dependent on the vehicle parameter.
