ABSTRACT:
A controller module for a wheelchair automatically, automatedly adjusts position of the wheelchair seat with respect to the wheelchair base. The wheelchair seat is pivotally connected to the wheelchair base, for movement of the seat with respect to the base by a powered actuator. The controller module includes a microprocessor connected to the powered actuator for operating the powered actuator to move the seat. A sensor, such as a 3-axis sensor, is connected to the microprocessor. The microprocessor performs a programmed sequence, to periodically adjust the seat position when the wheelchair seat is occupied, through feedback from the sensor. The controller module can provide medical and therapeutic benefits by operations of periodically adjusting the seat position, thereby varying a wheelchair occupant's pressure contacts, weights, and loadings against the seat.
