Abstract
An actuator device is disclosed that permits a first element to be moved linearly, in particular quasi-vertically, relative to a second element. The actuator device may be provided, in particular, for a vertical movement of a backrest, for example in a piece of seating furniture such as an office chair. The actuator device includes a displacement profile within a guide housing and a locking element. The displacement profile includes a latching row and the locking element is configured for engagement with the latching row. In a latching position, the locking element is resiliently rotated into the latching row of the displacement profile, and rotates back and forth when the displacement profile moves in a first direction with respect to the guide housing. In a release position, the locking element is rotated into a retaining position until it is disengaged from the latching row of the displacement profile.
