Document Type and Number:
WIPO Patent Application WO/2021/051689
Kind Code:
A1
Abstract:
A massage chair comprising a base (1), a chair frame (5), a rocking device (3), and a chair housing (2). The chair frame (5) is mounted on the base (1) by means of the rocking device (3). The rocking device (3) comprises a lower support plate assembly (31), an upper support plate assembly (32), a left torsion spring (33), and a right torsion spring (34). The lower support plate assembly (31) and the upper support plate assembly (32) are hinge-connected to each other by means of a connecting shaft (38). The left torsion spring (33) and the right torsion spring (34) are respectively sleeved at two ends of the connecting shaft (38). Upper ends of the left torsion spring (33) and the right torsion spring (34) respectively abut the upper support plate assembly (32), and lower ends of the left torsion spring (33) and the right torsion spring (34) respectively abut the lower support plate assembly (31). The upper support plate assembly (32) is fixedly connected to two horizontal support frames (51) located at the bottom thereof. The lower support plate assembly (31) is mounted on the base (1). The massage chair is controlled by the horizontal left torsion spring (33) and the horizontal right torsion spring (34) located between the upper support plate assembly (32) and the lower support plate assembly (31). Compared with a conventional non-electric rocking device in which a chair housing (2) is reset by a vertical spring located on a lower side of a lower support plate assembly (31), the massage chair is small in size, and adapts to various existing specifications.
