Description

Novel wheelchair

Technical Field

The utility model relates to a wheelchair technical field, concretely relates to novel wheelchair.

Background

Wheelchairs are chairs equipped with wheels to help replace walking and are classified into electric and manual folding wheelchairs. The wheelchair not only meets the requirements of physical disabilities and mobility-handicapped people for riding instead of walking, but also is more important to facilitate the family members to move and take care of the patients, so that the patients can do physical exercises and participate in social activities by means of the wheelchair.

The most important consideration when selecting a wheelchair is the size of the wheelchair. The main parts of the wheelchair-ridden person who bear weight are around the ischial tuberosities of the buttocks, around the femurs, around the women's sockets and around the scapulae. The size of the wheelchair, particularly the width and depth of the seat and the height of the backrest and the distance between the pedals and the seat cushion are proper, so that the blood circulation of the rider related to the acting part is affected, and skin abrasion and even pressure sore are generated. In addition, problems of patient safety, handling ability, weight of the wheelchair, place of use, appearance, etc. are also considered.

In the prior art, the bearing capacity of the conventional wheelchair is limited in a small range, and the stability of the conventional wheelchair is not ideal. Wheelchair users are usually ill patients with certain physical or mental conditions, and due to factors such as physical coordination or posture, the center of gravity of the wheelchair users is often relatively forward, and the ability of the wheelchair users to adjust the physical balance is generally poor, so that the stability of the wheelchair is particularly important. In addition, when the user is bulky and heavy, the above problem is particularly prominent; moreover, such a person exerts a large pressure on the backrest of the chair, and is prone to deformation of the backrest when the person sits down on the backrest of the wheelchair for a long time.
