ABSTRACT:
A wheelchair includes a chair member formed of a seat portion with a backrest portion vertically extending therefrom. On each of two opposing sides of the backrest is an armrest that pivots between a horizontal, deployed position when in use, and a stowed, vertical position when a patient is entering or exiting the seat. The chair is mounted on an electronics housing that includes a pair of reversible DC motors and associated gear boxes that rotate a pair of pneumatic tires. A caregiver can stand on a platform behind the chair member when operating the wheelchair. The chair's speed and direction are controlled with either of a pair of control panels. A caregiver's control panel is mounted on a steering bar attached to the rear surface of the backrest while a patient control panel is mounted on one of the armrests.
