Patent ID: 7661696

Claim:
A wheeled chair system comprising: a base member comprising a plurality of wheels and a lift device selectably extendable upwardly from and integrated with the base member, the lift device including a lift device motor; a substantially planar seat member coupled to the lift device and oriented substantially orthogonal to the direction of motion of the lift device when the lift device is in operation; a leg bracing member rotatably coupled to the substantially planar seat member and extending therefrom, including a first mode wherein the leg bracing member extends downwardly from the substantially planar seat member and a second mode wherein the leg bracing member extends substantially collinearly from the substantially planar seat member; a back bracing member rotatably coupled to the substantially planar seat member and extending therefrom, including a first mode wherein the back bracing member extends upwardly from the substantially planar seat member and a second mode wherein the back bracing member extends substantially collinearly from the substantially planar seat member; a single bracing motor operably coupled to the leg bracing member and the back bracing member to move at least one of the back bracing member and the leg bracing member between corresponding first and second modes, the bracing motor being located directly underneath the planar seat member; and an actuator module coupled to the bracing motor and to the lift device motor, wherein the actuator module selectably activates the bracing motor and the lift device motor simultaneously.
