AIR SUPPORT SYSTEM

An air support system includes an outer plate having a lateral portion in which a recessed space is formed. The air support system further includes an inner plate hingedly coupled to the outer plate and configured to be rotatable about the outer plate, where the inner plate includes a protruding portion protruding toward the recessed space of the outer plate. The air support system also includes a bladder part provided between the outer plate and the inner plate. The bladder part includes a sub-part disposed within the recessed space of the outer plate, and a main part disposed on a lower surface of the inner plate, where the inner plate is configured to rotate based on expansion of the sub-part.
