WIPO Patent Application WO/2024/020719
Kind Code:
A1
Abstract:
A foldable wheelchair, relating to the technical field of medical instruments and used for solving the technical problem that the folding and unfolding processes of existing foldable wheelchairs are complicated in that armrests (70) cannot move synchronously in the folding and unfolding processes. The foldable wheelchair comprises a front support frame (10), a backrest support (20), and armrests (70). The armrests (70) and the front support frame (10) are rotatable relative to the backrest support (20). The armrests (70) are each provided with a first limiting part and a second limiting part. The backrest support (20) is provided with a first limiting structure. The front support frame (10) is provided with a second limiting structure (12). The first limiting structure is configured to be capable of abutting against and moving synchronously with the second limiting part when the foldable wheelchair is folded, and to be capable of abutting against and moving synchronously with the first limiting part when the foldable wheelchair is unfolded. When the foldable wheelchair is folded or unfolded, the armrests (70) can move synchronously with the backrest support (20), and there is no need to fold or unfold the armrests (70) in advance, so that the folding process is simplified and the user experience is improved.
