Abstract
An adjustable wheelchair and components thereof are provided. The wheelchair may include a first chassis connected to a first wheel on a first side of the wheelchair. The first chasses may include a first strut configured to laterally translate while supporting a seat. The wheelchair may further include a second chassis connected to a second wheel on a second side of the wheelchair. The second chasses may include a second strut configured to laterally translate while supporting the seat. A jack may be connected to the first chasses and second chasses. The jack may operatively cause the first and second chassis expand away from each other and contract toward each other to vary a width between the first side and second side of the wheelchair.
Claims17
A wheelchair, comprising:
- a seat comprising a rail on a bottom side of the seat;
- a first chassis connected to a first wheel on a first side of the wheelchair, the first chassis comprising a first strut configured to laterally translate and slide along the rail while supporting the seat;
- a second chassis connected to a second wheel on a second side of the wheelchair, the second chassis comprising a second strut configured to laterally translate and slide along the rail while supporting the seat;
- and
- a jack connected to the first chassis and second chassis, the jack operatively configured to cause the first and second chassis to expand away from each other and to contract toward each other to vary a width between the first side and second side of the wheelchair.
A wheelchair, comprising:
- a first chassis connected to a first wheel on a first side of the wheelchair, the first chassis comprising a first strut configured to laterally translate while supporting a seat;
- a second chassis connected to a second wheel on a second side of the wheelchair, the second chassis comprising a second strut configured to laterally translate while supporting the seat;
- and
- a jack connected to the first chassis and second chassis, the jack operatively configured to cause the first and second chassis to expand away from each other and to contract toward each other to vary a width between the first side and second side of the wheelchair,
- wherein the seat comprises a backrest, the backrest comprising flaps configured to fold behind or substantially perpendicular to a central portion of the backrest,
- wherein the seat further comprises armrests connected to the flaps of the backrest, respectively, wherein the armrests are configured to fold from a horizontal to a vertical position, wherein the armrests are configured to fold behind the backrest in response to the flaps of the backrest being folded.
A wheelchair comprising:
- a seat comprising a rail on a bottom side of the seat;
- a first chassis connected to a first wheel and the seat, the first chassis configured to slide along the rail and support the seat;
- a second chassis connected to a second wheel and the seat, the second chassis configured to slide along the rail and support the seat;
- and
- a jack configured to move the first and second chassis to vary the width of the wheelchair.
