A recently granted patent (Publication Number: US11753168B2) describes a lower structure for a seat unit in an aircraft. The lower structure is made of a composite member and is designed to support a seat. It consists of a hollow box structure with a bottom surface for attaching it to the floor, at least two side wall surfaces extending upwards from the bottom surface, and a top surface for supporting the seat. The top surface is parallel to the bottom surface and is connected to the side wall surfaces. The lower structure includes brackets and fitting portions that allow it to be attached to seat rails in the aircraft at three attachment points on the bottom surface.

In addition, the hollow box structure of the lower structure has an opening in the front direction, which has a quadrilateral shape. A partition plate is also included in the hollow box structure to divide it into smaller sections. The composite member of the lower structure has blocks embedded at each attachment point, with one bracket coupled to each block. The thickness of the composite member is reduced at the area where the brackets are coupled to the blocks, compared to the rest of the composite member. The lower surface of the composite member at the bracket attachment area has a recess, while the upper surface is flat.

The patent also describes a seat unit that includes the aforementioned lower structure and an upper shell positioned above it. The upper shell is formed above the lower structure and provides additional support. The seat unit shares similar features with the lower structure, including the hollow box structure with a front opening, a quadrilateral shape for the opening, a partition plate, attachment points for seat rail attachment, blocks embedded in the composite member, and brackets coupled to the blocks.

Furthermore, the patent discloses a multi-person seat unit that is supported by the lower structure. This seat unit has the same characteristics as the previously mentioned seat unit, including the hollow box structure, front opening, quadrilateral shape, partition plate, attachment points, blocks, and brackets.

Overall, this patent presents an innovative design for the lower structure of a seat unit in an aircraft. The use of a composite member and the specific features described aim to provide a sturdy and efficient support system for seats in an aircraft.
