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.

Abstract: A backrest device includes a backrest carrier having a support arm, a backrest mounted on the support arm, and an actuator that is adjustable between a blocking position and a movement position. The support arm is equipped with a latching row. The backrest is movable along the support arm. The actuator is connected to the backrest and has an engaging piece. In the blocking position, the engaging piece is engaged with the latching row, so that a movement of the backrest along the support arm is blocked. In the movement position, the engaging piece is disengaged from the latching row, so that the backrest is movable along the support arm. The actuator is manufactured in one piece from an elastic material, in the movement position the actuator being elastically deformed by a manually applied force, so that the engaging piece is moved out of the latching row.

Abstract: A fastening element comprises a first clamping element and a second clamping element rotatably mounted about an axis of rotation on the first clamping element. The first and second clamping elements each have a first or second lever section, which extends essentially perpendicular to the axis of rotation, and a first or second connecting section, which extend away from that essentially parallel to the axis of rotation. The first lever section and the second lever section are moveable relative to one another about an axis of rotation between a splayed lever position and a non-splayed lever position. The first clamping element and the second clamping element are configured to hold the article when the first lever section and the second lever section are located in the splayed lever position, and to not hold the article when they are located in the non-splayed lever position.

Abstract: A cable routing arrangement for routing cables in an orderly fashion on a height-adjustable furniture item is disclosed that includes a rigid first routing element, a rigid second routing element, and a deformable connecting element. The first routing element has a first bearing arrangement that is configured to be pivotally connected to a top part of the furniture item. The second routing element has a second bearing arrangement that is configured to be pivotally connected to a base part of the furniture item. The first routing element and the second routing element can be interconnected via the connecting element in such a way that they are movable.
