The location of the apartment stairwell is quite inconvenient and dangerous.

Therefore, the inventor based on the above inconvenience and the lack of use, is not The research on the concept of improvement and innovation, and the active research and development, so that the invention is produced.

The main object of the present invention is to provide a backrest bag structure for people with reduced mobility, which is designed with a foldable seat-like bag back frame, which is convenient to carry and does not occupy space, and can be utilized in use. It is easy to carry the person with reduced mobility on the back and it is more convenient and safe to use.

In order to achieve the above purpose, the present invention is mainly provided with a foldable main body bracket and a sleeve which is sleeved on the outside of the main body bracket, wherein the main body bracket has a seat-like design and a support is provided on the back of the chair. The bottom plate of the support plate is respectively coupled with a pad frame through the steering device, and the bottom of the seat frame is combined with two collapsible legs; the sleeve has a back pad portion and a seat cushion portion, and The cover plate and the seat cushion frame are respectively sleeved on the support frame, and the cover pad is provided with two straps for carrying and a plurality of fixing straps; thereby forming a back pocket structure. When in use, the person with reduced mobility can ride on the back bag, and the person with the mobility can be fixed by the fixed strap body, and the carrying person can easily carry the person with reduced mobility to the back with the strap, and use the strap. More convenient and safe. In addition, when the carrying bag is carried or stored, the stand body can be folded inwardly and flatly attached to the bottom of the seat frame, and the seat frame can be folded against the support plate by the steering device. The overall volume is quite light and easy to carry, and it is not only easy to carry but does not take up space.
