Abstract: A height-adjustable piece of furniture includes a lower part, an upper part, an actuating device, first and second reference sections and a deformation sensor. Distance between the lower and upper parts can be adjusted by the actuating device. The deformation sensor is arranged to detect change between the first and second reference sections and is connected to the actuating device such that a signal of the deformation sensor can be transmitted to the actuating device. The actuating device is configured to stop the change in distance between the lower and upper parts if the signal transmitted by the deformation sensor corresponds to a change in distance that exceeds predefined threshold values. A cable protector is also provided for a cable to be mounted, and is coupled to the first and second reference sections such that tensile force acting on the cable causes change between the first and second reference sections.

Abstract: A chair is disclosed having a mechanism with a spring unit that permits mutually synchronous deflection between a backrest and a seat over a range between a respective zero position of back and seat inclination and a respective maximum back or seat inclination. Stationary first and second axes of rotation extend through a base support of a carrier unit. A back carrier is articulated on the first axis of rotation, and a third axis of rotation extends through the back carrier. A front of a base plate lies movably on the base support and a rear of the base plate is articulated on the third axis of rotation. The base support has a U-shape with two arms thereof having portions extending upward to engage associated openings in the base plate. When the mechanism is deflected, a relative displacement between the arms and the openings occurs.

Abstract: A height-adjustable frame for furniture, such as a worktable or desk, is disclosed. The frame includes first and second height-adjustable leg elements pivotable about first and second pivot axes between folded-out and folded-in positions. A rotatable shaft is arranged between the first and second leg elements to synchronously drive first and second height adjustment arrangements. The shaft includes a middle section and first and second end sections pivotable towards the middle section about respective first and second joint axes. A locking structure is included that locks the first and second leg elements in a folded-out position, when the first and second joint axes do not run approximately parallel to the first and second pivot axes, and that unlocks when the first and second joint axes run approximately parallel to the first and second pivot axes to permit the first and second leg elements to pivot into a folded-in position.

Abstract: A furniture composition comprises a first workstation having a first worktop adjustable in a vertical direction, a second workstation having a second worktop adjustable, independently of the first worktop, in the vertical direction, and a height-adjustable partition which extends in the vertical direction between the first and second workstation. A first support element is provided on the first worktop, by means of which the partition can be supported in the vertical direction, and a second support element on a second worktop, by means of which the partition can be supported in the vertical direction.
