The chair includes a base member, a support member, at least a linkage member configured on the base member and to a bottom side of the support member in a movable manner, at least a first power assembly connected between the support member and the linkage member, and a second power assembly connected between the linkage member and the base member. The first power assembly provides an angle variation between the support member and the linkage member, whereas the second power assembly provides a separate angle variation between the linkage member and the base member. The chair provides both stand-up assistance and comfortable reclining, and has fewer components, less cost, more flexible and smooth linkage, and requires less power to operate.

An armchair comprising a seat chassis supported on a support chassis by a pair of support columns, a chair back structure pivotally attached to a rear end of the seat chassis and to the support chassis, and a leg support structure pivotally attached to a front end of the seat chassis and connected to a beam, wherein the beam is attached the chair back structure. A first actuating device is mounted to the chair back, where a protracting end of the first actuating device is connected to the seat chassis. The armchair further comprises a second actuating device mounted to the support chassis, a footrest connected to a protracting end of the second actuating device, a third actuating device attached to the seat chassis, and a seating structure connected to a protracting end of the third actuating device and mounted above the seat chassis, wherein the seating structure includes an operative position projecting upwards and forwards by the third actuating device at a tilting angle from the seat chassis.

Joystick chair is an input device for interaction between the user and computer. It enables the movement of the user in games. The invention is used by placing feet on the platform (3) and sitting or leaning on the seat (23). Command for turning is achieved by rotating the seat (23), either to the left or to the right. Command for forward movement is issued by pulling the left or right controller (36, 41) with fingers, while the command for backward movement is issued by pushing the left or right controller (36, 41) away by palms. Control handles for lateral movement (49, 56) are separated from the forward-back controls that are located on the controllers (36, 41). Other commands are achieved with buttons on the left and right controller and they are accessible with thumbs. The software allows the modifications of all available actions of the invention.
