Abstract
A chair is disclosed having a chair frame and a seating surface having a first side surface movably coupled to the frame, and a second side surface coupled to the frame. The first side surface is independently moveable relative to the second side surface. Each of the first side surface and the second side surface define a front end of the seating surface and a back end of the seating surface. A first actuator is coupled to the frame, where the first actuator is configured for operative communication with the first side surface.
Claims17
A chair comprising:
- a chair frame;
- a seating surface comprising a first side surface movably coupled to the frame and a second side surface coupled to the frame, wherein the first side surface is independently moveable relative to the second side surface and each of the first side surface and the second side surface define a front end of the seating surface and a back end of the seating surface, wherein the seating surface has a collapsed position and an expanded position, and wherein the chair has a greater width when the seating surface is in an expanded position than the width of the chair in the collapsed position;
- a first actuator coupled to the frame, wherein the first actuator is configured for operative communication with the first side surface;
- and
- wheels coupled to the frame, wherein the wheels comprise drive wheels and castor wheels.

- a seating surface comprising a first side surface and a second side surface, wherein the first side surface is independently moveable relative to the second side surface and each of the first side surface and the second side surface define a front end of the seating surface and a back end of the seating surface, the seating surface having a collapsed position and an expanded position;
- a first actuator coupled to the chair frame;
- and
- a first mechanical communication chain configured to mechanically couple the first actuator and the first side surface when the seating surface is in the expanded position, and the first mechanical communication chain is configured to be disengaged to mechanically isolate the first actuator from the first side surface when the seating surface is in the collapsed position.
