Electric wheelchairs, which are often called power chairs, have been around for over fifty years and are very important, because many people are not able to use a manual wheelchair, which requires a great deal of upper body strength. However, power chairs have changed a great deal since when they were first invented.
The power chairs of fifty years ago were simply manual wheelchairs that had been fitted with an electrical motor. The E & J manual wheelchair was very popular at the time and consisted of a foldable frame made up of hollow steel tubes. A number of companies began to develop power chair converter kits, which could be easily added to the E & J frame, turning it into an electric wheelchair. Today, while the influence of the E & J design can still be seen in most manual wheelchairs, power chairs are actually much different.
Modern power chairs consist of a molded plastic base, which consists of the wheels, electric motor, rechargeable battery, and other electrical components. A chair is attached to the base, which in someways looks similar to a high-end office chair, except many also include an adjustable headrest.
The chair, which is referred to as the Captain’s Chair, usually has an adjustable height and armrests that can be raised or lowered to make it easier to transfer into and out of the electric wheelchair. Typically, the chair can be quickly removed from the base of the power chair, to make it easier to transport.
While there have been many changes to the power chair over the years, one thing that has remained the same is the way the wheelchair is controlled. Of course there have been many technological advances, but the joystick has been the traditional wheelchair control since they were first developed. The joystick of the wheelchair allows the wheelchair to be moved in any direction by simply pushing the joystick in the desired direction. An electric throttle, which controls the speed of the power chair, is also usually attached to the captain chair’s armrest.
The joystick control usually only requires a single finger to operate, but for some using the standard control is not possible, so a number of alternate controls exist. Alternate controls can be as simple as a allowing for head movements to move the electric wheelchair, but there are many much more advanced control systems available.
Today, portable power chairs are becoming more popular and manufacturers have begun to manufacture travel power chairs, which are designed to be quickly and easily disassembled into several easy to manage pieces. Individually the pieces are typically rather light, which means the wheelchair can be transported without requiring a wheelchair lift or other type of wheelchair carrier. Of course, to help reduce weight, they usually lack features and do not have as comfortable of a chair. However, portable power chairs can be very useful for those who will be traveling on a plane or other form of public transportation.
Power chairs are today very common, but the manual wheelchair is still the most used type of wheelchair.
