Claim:
A medical examination chair for seating and moving a patient, the medical examination chair comprising: a stationary column; a horizontal shaft supported by the stationary column, the horizontal shaft having a first axis of rotation; a primary arcuate member connected to the horizontal shaft and having a first end and a second end, the primary arcuate member having a toothed plate and a stop plate, wherein the primary arcuate member is configured for performing a first rotary movement about the first axis of rotation; a secondary arcuate member supported for rotation by the primary arcuate member about a second axis of rotation through the first end and the second end of the primary arcuate member, the secondary arcuate member arranged inside the primary arcuate member, the second axis of rotation substantially perpendicular to the first axis of rotation, wherein the secondary arcuate member is configured for performing a second rotary movement about the second axis of rotation; a seat supported by the secondary arcuate member; a first mechanical abutment supported by the stationary column to abruptly stop the primary arcuate member relative to the stationary column at an end of the first rotary movement of the primary arcuate member, the first mechanical abutment having a damper and a ring; and a second mechanical abutment supported by the primary arcuate member to abruptly stop the secondary arcuate member relative to the primary arcuate member at an end of the second rotary movement of the secondary arcuate member; wherein the damper is configured to block the stop plate, and the tooth of the toothed plate is configured to trap the ring, thereby suddenly stopping the first rotary movement of the primary arcuate member.
