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.
