There are mainly handles, armrests, waist belts, leg belts, pedals, rear wheels, hand wheels and front wheels
The function of the hand grip is that the person who pushes the elderly behind mainly controls the structure of the wheelchair. The main point is that the material and ergonomic texture of the hand grip can make the person behind the wheelchair feel that the direction is controllable, and the hand touches the wheelchair. The location material should be comfortable. Sometimes people with poor back muscle strength can also use it to better grasp the body balance.
·The function of the armrest is to provide a place for the large and small arms of the person in the wheelchair, so that the upper limbs of the person in the wheelchair will not fall through the air. Armrest types are available in full length: provide full support for the elderly's arms. Half-length: It can make the distance between the wheelchair and the coffee table closer. In terms of structure, there are fixed, removable armrests and liftable armrests.
·The function of the belt is that when riding a wheelchair, the autonomous mobility is not high, and the belt can better help fix the elderly in the wheelchair.
·The role of the leg strap is to provide a support point for the calf, preventing the legs from slipping backwards from the pedals when riding.
·Pedals provide support points for the feet and calves. There are fixed pedals, rotating pedals, detachable pedals, and tiltable pedals. The height should refer to the length of the calf, and note that the pedal is at least 5 cm from the ground.
·The rear wheel is the driving wheel of the entire wheelchair. The reason why the rear wheel is large is that the larger the rear wheel, the easier it is to drive. Wheelchair tires are about the same size as bicycle tires, so they can be replaced at a bicycle shop after convenience. Types of tires: pneumatic, solid rubber. Inflated tires can have a cushioning effect, and it is more comfortable for the elderly to sit up, but they usually need to be pumped up, and there are cases of tire blowouts. It is made of solid rubber and does not need to be inflated frequently, but when the road is rough, the elderly will not be comfortable enough to sit up.
·The hand wheel is the structure used by the elderly to push the wheelchair. The material of the hand wheel should not be too smooth, because it needs the friction of the hand to drive.
·The front wheel is a small wheel that can rotate freely around the shaft, and most of them are universal wheels. There are small and big front wheels, the small ones are easy to turn, but it is a bit difficult to go up the steps, and the big wheels are easier to go up the steps, and the steering is not particularly convenient. Like the front wheels, the rear wheels are also available inflatable and solid.
In addition to the basic components of a wheelchair, there are some accessories such as a wheelchair table, heel rings, anti-tipping devices, wheelchair bandages, and wheelchair gloves.
