Abstract

The present disclosure relates to a seat apparatus including a seat frame; a connection bracket coupled to the seat frame; and a back frame comprising a hinge portion and a distal end portion. The hinge portion may be coupled to the connection bracket. The seat apparatus may further include: a first connection shaft coupled to the seat frame and configured to raise or lower the seat frame; and a second connection shaft coupled to the connection bracket and the back frame. The back frame may be configured to pivot around the second connection shaft between: a flat position, in which the hinge portion and the distal end portion are arranged in a horizontal direction, and a reclined position, in which the distal end portion is reclined and disposed to be further away from the seat frame than the hinge portion.
