A linear actuator for a furniture system comprises at least one axial flux motor (5) having a rotor (9), and at least one motion mechanism (6) attached to the rotor (9). The motion mechanism (6) is adapted to cause a linear movement of the linear actuator.

An electrically adjustable furniture system comprises at least one such linear actuator. A furniture system arrangement comprises at least one first and at least one second such electrically adjustable furniture system. A method of installing a linear actuator in a furniture system comprises the steps mounting at least one axial flux motor (5), mounting at least one motion mechanism (6), and connecting the at least one motion mechanism (6) to a rotor (9) of the at least one axial flux motor (5).

An automated adjustable seating system (10) comprising: a seat (16), the seat (16) incorporating a first sliding frame (62) and seat upholstery attached to the sliding frame (62); a backrest (20), the backrest (20) incorporating a second sliding frame (138) and back upholstery attached to the sliding frame (138); a set of actuators (106, 128, 194, 196, 198); and a control system (200). The set of actuators (106, 128, 194, 196, 198) includes an actuator for adjusting the angle of the seat (16) relative to the horizontal (194), an actuator (106) for adjusting the longitudinal position of the first sliding frame (62); an actuator (196) for adjusting the angle of the backrest (20) relative to the vertical and an actuator (198) for adjusting the longitudinal position of the second sliding frame (138). Each of the set of actuators (106, 128, 194, 196, 198) is controlled by the control system (200).

An electro-mechanical automatic self-leveling device is provided for use on motorized chair seats. The device may include a pendulum assembly consisting of neodymium magnets attached to an inertia-dampened pendulum and a printed circuit board (PCB) with a hall effect sensor and processing circuitry that will develop proportional correction signals to be amplified by a high-current bi-directional motor driver. This configuration is assembled in a case attached to the motorized chair seat via a mounting bracket and clamping knob, and a cable from the device connects to the chair's seat tilt motor and power supply. Various switches may be included to reset the device in case of overheating and to switch between automatic and manual leveling. In alternative embodiments, the auto-leveling mechanism may be integrated into the motorized chair seat design rather than a separate device that can be attached to the chair seat after-market and independent of the chair's controller.

A seating furniture chassis comprises a base body, first and second side parts, a back part, a plurality of electrically conductive cables fastened to the base body, and first and second fasteners arranged on the base body. The back part is releasably fastenable to the first fastener and the first and second side parts are respectively releasably fastenable at two opposite sides of the base body to the second fastener, a plurality of individual connectors, and a central connector. Each electrically conductive cable connects one of the individual connectors to the central connector.

A seating furniture chassis comprises a base body, a plurality of electrically conductive cables fastened to the base body, and a central connector. Each of the electrically conductive cables has a first end and a second end. The first end of each electrically conductive cable has an individual connector that is electrically connectable to a peripheral electrical device. Each of the electrically conductive cables is electrically connected at the second end to the central connector. The central connector is connectable to a central electrical device (e.g., a control unit). The central electrical device is configured to receive and process first control signals from an operating device.
