  • Publication number: 20220041087
    Abstract: The present invention relates to an inbuilt seat leg support and a seat. The seat leg support is mounted in a seat. The seat includes a base frame and a cushion frame located above the base frame. A receiving space is formed between the base frame and the cushion frame. The seat leg support includes a leg support frame configured to be received in the receiving space. The leg support frame is movable and adjustable relative to the cushion frame. Movement and adjustment of the leg support frame cause the leg support frame to extend out of the receiving space to be in an extended state or to retract into the receiving space to be in a received state. According to the present invention, a receiving space for a leg support frame is reserved between a base frame and a cushion frame, and the leg support frame is disposed to be movable so that the leg support frame can be received in the receiving space when not in use. Receiving a leg support in a seat causes the present invention to be space-saving.
