Abstract
A drive motor-linear actuator system, for use within, for example, powered chairs, comprises a single drive motor provided with a pair of output drive shafts, and a pair of laterally spaced, left and right-side linear actuators operatively engaged respectively with the pair of output drive shafts. In this manner, the single drive motor can simultaneously actuate both linear actuators in a synchronized manner. The linear actuators are disposed near the opposite left and right sides of the chair so as to provide enhanced stability to the chair while reducing the weight and cost of the chair since only one single drive motor is required to drive both linear actuators.
