  • Patent number: 10722033
    Abstract: The present invention provides a bathing seat structure for use in a bathtub, wherein the legs frame enables fixed positioning of the base, and the base enables fixed positioning of the seat cushion. The base is provided with two freeing mechanisms, a lever, and a rolling device. After pulling open the lever, the rolling device enables the seat cushion to rotate. The two freeing mechanisms must be pressed to a predetermined depth and must be pressed simultaneously, only then can the seat cushion be shifted laterally, thus preventing inadvertent contact and causing displacement of the seat cushion. The rolling device uses a two-tier centrifugal configuration, thereby supporting equal distribution of a person's weight to achieve smooth rotation with no inclining of the seat cushion, and thus extending the serviceable life of the rolling device.
