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.
Claims18
A linear actuator system, comprising:
- a single drive motor having first and second output drive shafts respectively disposed within a pair of first housings;
- and
- first and second linear actuators operatively engaged with said first and second output drive shafts of said single drive motor such that said first output drive shaft of said single drive motor drives said first linear actuator, while said second output drive shaft of said single drive motor drives said second linear actuator, wherein motor ends of said first and second linear actuators are disposed within second motor housings which are connected to said pair of first housings within which said first and second output drive shafts are disposed.
A linear actuator system for incorporation within a powered chair, comprising:
- a single drive motor having first and second output drive shafts respectively disposed within a pair of first housings;
- and
- first and second linear actuators operatively engaged with said first and second output drive shafts of said single drive motor such that said first output drive shaft of said single drive motor drives said first linear actuator, while said second output drive shaft of said single drive motor drives said second linear actuator, wherein motor ends of said first and second linear actuators are disposed within second motor housings which are connected to said pair of first housings within which said first and second output drive shafts are disposed.
A powered chair having a linear actuator system incorporated therein, wherein said linear actuator system comprises:
- a single drive motor having first and second output drive shafts respectively disposed within a pair of first housings;
- and
- first and second linear actuators operatively engaged with said first and second output drive shafts of said single drive motor such that said first output drive shaft of said single drive motor drives said first linear actuator, while said second output drive shaft of said single drive motor drives said second linear actuator, wherein motor ends of said first and second linear actuators are disposed within second motor housings which are connected to said pair of first housings within which said first and second output drive shafts are disposed.
