First Claim
Patent Images
1. A method of automating movement of a user support surface of a power driven wheelchair to a predefined position, the method comprising:
- storing data representing a predetermined position of the user support surface of the power driven wheelchair in a non-volatile memory; and
associating the data with a user input so that a user can input the user input to cause the user support surface of the power driven wheelchair to automatically move to the predetermined position.

Abstract
By programming position parameters corresponding to user support surfaces of a power driven wheelchair, movement of the user support surfaces is automated. The user support surfaces can be positioned individually, as part of a sequence or as part of a series of sequences. Accordingly, with little effort, a user can position the user support surfaces of the wheelchair to a predefined position.

11. A method of automating movement of a plurality of user support surfaces of a power driven wheelchair to predefined positions, the method comprising:
-
storing data representing a predetermined position of each of the plurality of user support surfaces of the power driven wheelchair in a non-volatile memory; and
associating the data with a user input so that a user can input the user input to cause each of the plurality of user support surfaces of the power driven wheelchair to automatically move to the corresponding predetermined position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of automating movement of a plurality of user support surfaces of a power driven wheelchair to predefined positions, the method comprising:
-
storing first data representing a predetermined position of each of a first plurality of the user support surfaces of the power driven wheelchair in a non-volatile memory;
storing second data representing a predetermined position of each of a second plurality of the user support surfaces of the power driven wheelchair in the non-volatile memory; and
associating the first data and the second data with a user input so that a user can input the user input to cause the first plurality of the user support surfaces to automatically move to the corresponding predetermined positions and the second plurality of the user support surfaces to automatically move to the corresponding predetermined positions. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A wheelchair comprising:
-
a user support surface connected to a frame of the wheelchair;
an actuator for moving the user support surface;
a controller;
a memory; and
a communication connection between the controller and the actuator; and
wherein data representing a predetermined position of the actuator corresponding to a position of the user support surface is associated with a user input and stored in the memory; and
wherein if the controller receives the user input, the controller uses the communication connection to cause the actuator automatically to move to the predetermined position stored in the memory to move the user support surface to a corresponding position.

38. A controller for controlling movement of an actuator to move a user support surface of a wheelchair, the controller comprising:
-
a processor; and
a memory; and
wherein the memory stores data representing a predetermined position of the actuator corresponding to a position of the user support surface and a user input associated with the predetermined position; and
wherein the processor generates a signal for causing the actuator automatically to move to the predetermined position to move the user support surface to a corresponding position, in response to detecting the user input.
