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.

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, and the seat is moveable with respect to the base by a powered actuator. The controller module includes a microprocessor connected to the powered actuator. The microprocessor controls operation of the powered actuator, such as by varying power to the actuator. A sensor, such as a 3-axis sensor, is connected to the microprocessor. The sensor senses seat position and signals the microprocessor of the position. The microprocessor performs a programmed sequence, to periodically adjust the seat position when the wheelchair seat is occupied. The signal from the sensor is feedback to the microprocessor for operations according to the programmed sequence. The controller module includes interfaces for use in making selections among options for the programmed sequence.
