Abstract

A method of operating a wheelchair during an un-recline process, where the wheelchair includes a seat frame and a back frame, includes positioning the wheelchair user in the wheelchair with the back frame reclined, and rotating the seat frame of the wheelchair so that the seat frame and the back frame form an angle that is within the range of from about 80 degrees to about 120 degrees. The back frame is unreclined by rotating the back frame and the seat frame while maintaining the angle between the seat frame and the back frame within the range of from about 80 degrees to about 120 degrees.

Claims

AMENDED CLAIMS[received by the International Bureau on 14 January 2002 (14.01.02); original claims 1-15 replaced by new claims 1-16 (4 pages)]
1. The method of providing user conforming characteristics in a wheelchair comprising: a. providing a wheelchair having at least two movable frame members that are movable with respect to an initial position; b. programming the wheelchair by: positioning a wheelchair user in the wheelchair and moving a first one of the at least two movable frame members through a sequence of movement from the first movable frame member's initial position to subsequent positions; adjusting the position of a second one of the at least two movable frame members to conform the second movable frame member to the user in response to the movement of the first movable frame member; and measuring the amount of adjustment of the second movable frame member during the sequence of movement of the first movable frame member, and storing the measured amounts of adjustment; and c. operating the wheelchair by automatically adjusting the position of the second movable frame member in response to movement of the first movable frame member and in accordance to the measured amounts of adjustment, thereby providing user conforming characteristics in the wheelchair.
2. The method of claim 1 including the step of storing the measured amounts of adjustment in a memory device, and wherein the step of automatically adjusting the position of the second movable frame member includes accessing the memory device.
3. The method of claim 1 in which the movable frame members are from the group consisting essentially of seat frame, back frame, headrest, foot rest, leg rest, and arm rest.
4. The method of claim 1 in which the sequence of movement of the first movable frame member is a continuum of different positions.
5. The method of providing shear reducing characteristics in a wheelchair comprising: a. providing a wheelchair having a back frame and a shear plate, the shear plate being movable with respect to the back frame, and the back frame being mounted for reclining at various angles of recline with respect to an initial position; b. programming the wheelchair by: positioning a wheelchair user in the wheelchair and reclining the back frame from the initial position through a recline sequence of several different angles of recline; adjusting the shear plate with respect to the back frame at each of the several different angles of recline to minimize the shear experienced by the user at each of the several different angles of recline; and measuring the amount of adjustment of the shear plate at each of the several angles of recline; and c. operating the wheelchair by automatically adjusting the shear plate with respect to the back frame as the wheelchair back frame is reclined, thereby providing shear reducing characteristics in the wheelchair.
6. The method of claim 5 including the step of storing the measured amounts of adjustment associated with each of the several angles of recline in a memory device, and wherein the step of automatically adjusting the shear plate with respect to the back frame includes accessing the memory device.
22
7. The method of claim 5 including storing the measured amounts of adjustment associated with each of the several angles of recline in a memory device, providing a means for moving the shear plate with respect to the back frame, providing a sensor for sensing the angle of recline of the wheelchair, and controlling the movement of the shear plate with respect to the back frame with a controller that accesses the memory device and responds to the sensed angle of recline to provide the shear reducing characteristics in the wheelchair.
8. The method of claim 5 in which the recline sequence is a continuum of different angles of recline.
9. The method of operating a wheelchair during an un-recline process, the wheelchair including a seat frame mounted for tilting and a back frame mounted for reclining, the method comprising: providing a back frame actuator for reclining and unreclining the back frame; sensing the position of the back frame during reclining and unreclining with a recline sensor; providing a tilt actuator for tilting and untilting the seat frame; sensing the position of the seat frame during reclining and unreclining using a tilt sensor; providing input from the recline sensor and the tilt sensor to a controller; storing the recline sensor and tilt sensor input in the controller; and controlling the reclining of the back frame and the tilting of the seat frame by sending signals to the recline actuator and the tilt actuator in response to the stored input.
10. The method of claim 9 in which the controlling of the unrecline of the back frame includes sending a signal from the controller to the tilt actuator to tilt the seat frame.
23
1 1. The method of claim 10 including tilting the seat frame prior to unreclining the back frame.
12. The method of claim 9 in which tilting of the seat frame prior to unreclining the back frame forms an angle between the back frame and the seat frame that is within the range of from about 80 degrees to about 120 degrees.
13. The method of operating a wheelchair during an un-recline process, the wheelchair including a seat frame mounted for tilting and a back frame mounted for reclining, the method comprising: providing a back frame actuator for reclining and unreclining the back frame; providing a tilt actuator for tilting and untilting the seat frame; and sending a signal from a controller to the back frame actuator to unrecline the back frame and sending a signal from the controller to the seat frame actuator to tilt the seat frame upward during the un-recline process.
14. The method of claim 13 including tilting the seat frame upward before the back frame is unreclined.
15. The method of claim 13 in which ti lting of the seat frame prior to unreclining the back frame forms an angle between the back frame and the seat frame that is within the range of from about 80 degrees to about 120 degrees.
16. The method of claim 13 including providing a recline sensor for sensing the position of the back frame during reclining and unreclining, providing a tilt sensor for sensing the position of the seat frame during reclining and unreclining. and providing input from the recline sensor and the tilt sensor to the controller during the un-recline process.
