It is called "eight-figure" wheelchair, which is wide at the bottom and narrow at the top. In order to ensure the safety of athletes, it is not easy to roll over. Disabled athletes who participate in competitions and other competitions turn wheelchairs into extensions of the body, which takes the engineering design of sports wheelchairs to a new level, especially for racing models, while incline wheelchairs are designed with patient comfort and safety in mind first, mobility and lightweight materials are key attributes of sports wheelchairs. Clearly, the direction of assistive technology is to design designs that suit the specific needs of individuals. A tilting wheelchair is a removable decompression device in which the seat of the wheelchair can be tilted in a range of 0 to 40 degrees while the wheels remain stable on the ground. While typically made of aluminum or steel, this design makes wheelchairs compact and heavy, either manual, which is propelled by a caregiver, or electric, which is operated by the user himself via a centralized control panel. Patients can still maintain proper orientation through communication and electronic medical devices, and reclining wheelchairs also prevent various types of shear forces, which are caused by friction against skin tissue due to dragging over surfaces; The tilting wheelchair was originally conceived as a life-saving device that would provide mobility for paraplegics, allowing users to perform at their best in all aspects of life.
