  • Publication number: 20250128651
    Abstract: A conveyance seat capable of suppressing wrinkles or saggings from occurring on a surface of a seat main body is provided. A conveyance seat includes a seat back and a movable body which is attached inside the seat back, is disposed at an outer position in relation to a center portion of the seat back, and is operated so that a side portion of the seat back protrudes toward a seated occupant side (seat front side). The movable body is disposed on a back surface of a cushion material in the side portion. An end portion (rear end portion) on the side opposite to the seated occupant side of the movable body is disposed on the seated occupant side (seat front side) in relation to a seating surface of the center portion of the seat back.
