Abstract
A wheelchair including: a frame including a backrest portion; and a drive wheel attached to the frame using an axle, wherein the axle is attached below the backrest portion and is configured to have the drive wheel rotate about the axle; a front caster connected to the frame and horizontally offset from the drive wheel; and a relative positioning mechanism connected to the frame and the front caster assembly, wherein the relative positioning mechanism is configured to locate the front caster assembly at two or more positions relative to the frame along a vertical direction.
Claims20
A wheelchair, comprising:
- a frame including a backrest portion;
- and
- a drive wheel attached to the frame using an axle, wherein the axle is attached below the backrest portion and is configured to have the wheel rotate about the axle;
- a front wheel connected to the frame and horizontally offset from the drive wheel;
- and
- a relative positioning mechanism connected to the frame and the front wheel, wherein the relative positioning mechanism is configured to locate the front wheel at two or more positions relative to the frame along a vertical direction.
A method of manufacturing a wheelchair, the method comprising:
- determining a user measurement profile representing physiological measurements of a user;
- calculating locking positions for a tilt assembly based on the user measurement profile, wherein the locking positions correspond to changing positions of a backrest of the wheelchair relative to a vertical direction;
- forming a frame for the wheelchair according to the user measurement profile;
- and
- forming the tilt assembly operably coupled to the frame, wherein:
- the tilt assembly is formed according to the locking positions and the user measurement profile, and
- the tilt assembly is configured to change a position of a caster wheel along a vertical direction relative to the frame.
A system for manufacturing a wheelchair, the system comprising:
- a seating system interface configured to receive a user measurement profile representing physiological measurements of a user;
- one or more processors, operably coupled to the interface, configured to calculate locking positions for a tilt assembly based on the user measurement profile, wherein the locking positions correspond to changing positions of a backrest of the wheelchair relative to a vertical direction based on changing a position of a font wheel of the wheelchair along a vertical direction relative to a frame;
- and
- an output mechanism, operably coupled to the one or more processors, configured to communicate the locking positions for manufacturing the wheelchair.
