Abstract

In the case of a rotary actuator for an adjuster of a vehicle seat, in particular of a motor vehicle seat, having a manually actuatable operating element (7), a transmission gearing (11) on which the operating element (7) acts when actuated, and an output element (9) which is rotated at least intermittently by the transmission gearing (11) and, during a rotation, drives the adjuster (3), the transmission gearing (11) changing during the actuation by the operating element (7) from a higher transmission ratio to a lower transmission ratio, during the actuation by the operating element (7) the transmission gearing (11) runs through two phases during which the transmission ratios are constant in each case.
