Patent ID: 8454366

Claim:
An actuated support frame and chair assembly for transmitting motion to a chair with respect to a ground as a function of motion signals associated with video output, comprising: an actuated support frame comprising: a frame, the frame being expandable/retractable along at least one translational degree of freedom, support surfaces at corners of the frame and lying concurrently in a support plane, the support surfaces being displaceable with respect to one another in the support plane by expansion/retraction of the frame so as to be sized to support a chair, and at least two actuators interconnected by the frame and being positioned between the frame and the ground, the actuators each being in an actuated casing secured directly to the frame with one of the actuated casing on each lateral side of the frame, and each actuator comprising an output shaft against the ground, the actuator being adapted to receive signals, to selectively displace the frame with respect to the ground in synchronization with a video output; and a chair for seating at least one person, the chair comprising a base with an undersurface facing the ground to define a bottom of the chair and with an upper surface for supporting a seated person, and a backrest projecting upwardly from a rear side of the chair, the chair being positioned on top of the frame on the support surfaces with corners of the chair superposed with the corners of the frame and with the undersurface of the base being above the support plane; whereby the chair and the frame move concurrently with respect to the ground in synchronization with the video output.
