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, first and second fasteners arranged on the base body, wherein 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, and a plurality of individual connectors and a central connector, wherein the electrically conductive cables each connect one of the individual connectors to the central connector.

A chair support structure includes a base, a driving component, a first transmission component, a leg component, and a back component. The driving component can be connected to the base, the first transmission component is connected to the driving component. Both the leg component and the back component are connected to the first transmission component. The first transmission component can include a first transmission member. The first transmission member can include a first connection portion and a second connection portion, each of which has a first end and a second end opposite to each other. The first end of the first connection portion can be pivotally connected to the leg component. The second end of the first connection portion can be fixed to the second connection portion. An angle can be formed between the first connection portion and the second connection portion.

A furniture member may include a base frame, a chaise seat bottom frame, and a seatback frame. The chaise seat bottom frame is supported by the base frame and is movable relative to the base frame between first and second positions. The chaise seat bottom frame includes an upper-leg-supporting portion and a lower-leg-supporting portion that are fixed to each other. The lower-leg-supporting portion may support an occupant's lower legs in an extended position relative to the occupant's upper legs. The seatback frame may be supported by the base frame and may be movable relative to the base frame and the chaise seat bottom frame between upright and reclined positions. Movement of the seatback frame from the upright position to the reclined position causes movement of the chaise seat bottom frame upward and forward relative to an aft end of the base frame from the first position to the second position.

An orientable seating device includes a seat, the orientation of which can be controlled to dynamically affect a desired of yaw, pitch and roll. The seating device can be used to reorient and/or to simulate motion for a seated person for use with video games, virtual reality headsets or goggles, land, water, air or space vehicle simulation, or wireless airborne drones, for example. The device includes a seat mounted on a carriage, which is received in a carriage pedestal. Within the pedestal, a drive wheel positioned under the carriage supports and rotates the carriage by driving an outer sphere-shaped surface of the carriage. The drive wheel can be reoriented around a vertical axis such that any combination of pitch and roll can be achieved by rotating the wheel against the sphere-shaped surface. Yaw can be controlled by a rotatable platform upon which the carriage pedestal can be mounted.

A recliner or lift and recliner chair is provided having a recline or lift and recline chair mechanism with preferably with at least one recline or lift-recline actuator that controls a reclining movement or a lifting and reclining movement. The chair mechanism has a recline or lift-recline base, a seat and a back connected thereto. For additional functionality, a cradle assembly is provided in order to provide a cradling movement to the recline or lift-recline base. The cradle assembly can be provided by a system of standoffs and pivot connections, which can be direct or use links, or can be configured with a track and roller or slide system in order to achieve a desired cradling movement. A cradle actuator is connected between the cradle base and the recline or lift-recline base. A controller is provided that controls movement of the cradle actuator and preferably at least one recline or lift-recline actuator.

A seating furniture chassis comprises a seat surface frame, a backrest frame, two armrests, and a drive mechanism. The backrest frame is pivotable about a virtual pivot axis defined by two pivot points, wherein the backrest frame is fastened to the pivot points on the armrests. The drive mechanism is connected to the backrest frame by a translation mechanism. The drive mechanism is designed to trigger a translation of the translation mechanism, wherein the translation is converted into a pivoting movement of the backrest frame about the pivot axis. The backrest frame is connected below the pivot points to the seat surface frame so that during the pivoting movement the seat surface frame is moved translationally. The drive mechanism is arranged below a first lateral edge region of the seat surface frame.

A control system for a piece of furniture includes a control panel configured to receive input from a user, a control module configured to control actuators coupled to movable components of the piece of furniture, and a battery system. The control module is configured to, in response to the input from the user indicating an intent to return the movable components to respective home positions, perform a homing sequence. The homing sequence includes selecting a first actuator according to a specified order, determining a home location for the selected actuator, and beginning to drive the selected actuator toward the home location. The homing sequence includes repeatedly selecting a next actuator according to the specified order and repeating the determining and the beginning. The homing sequence includes determining whether mains electricity is present and, if not, pausing the repeatedly selecting until less than a threshold number of actuators are in motion.
