US Patent 9192540 Electric inversion table

An electric inversion table includes a base, a bench and a driving device. The bench is disposed on the base and is rotated between a horizontal position and a vertical position. The driving device connects the bench to the base for driving the bench to rotate between the horizontal position and the vertical position. When power failure occurs or a motor of the driving device is out of order, users can release locked status by a clutch of the driving device so as to turn the bench from the vertical position back to the horizontal position safely by the body weight.
