[0002] According to the requirements of my country's Civil Aviation Regulations CCAR121-R5, for expanded flight crews, it is necessary to provide rest facilities for crew members to ensure the quality of their rest.

[0003] The patent with the announcement number CN213057531U discloses a flat-lying rest device for crew members of civil aviation passenger aircraft, comprising a middle frame, on which a plurality of legs for engaging in guide rails are rotatably connected; both ends of the middle frame are hinged with connecting joints, and the other end of the connecting joint is hinged with side frames, and both ends of the middle frame and the side frames are connected with locking mechanisms, and pads are arranged in the middle frame and the side frames. By fixing the rest device to the gap in front of the seats in the cabin, a platform for crew members to lie flat and rest is formed.

[0004] However, in order to ensure that passengers do not feel tired after sitting for a long time, the seats in the aircraft cabin are usually designed to be ergonomic and to improve the coverage of the human buttocks. Therefore, the seat surface is designed to be uneven. Crew members tend to lean inwards of the seat when resting and are affected by the seat surface, making it uncomfortable to lie down.

DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses a multifunctional reclining chair for use in an aircraft, referring to Figure 1, including a support frame 1, the support frame 1 is composed of a plurality of movable frames 11, the movable frames 11 can be hinged to each other or hinged to each other through connecting components to form a foldable state, when the movable frames 11 form a flat support frame 1, the top wall of each movable frame 11 of the support frame 1 is installed with a cushion 12, the cushion 12 can be glued to the support frame 1 by Velcro, or can be directly fixed to the support frame 1. The support frame 1 is placed on the seat surface 21 of the seat 2 in the aircraft cabin, the edge of the support frame 1 away from the backrest 22 of the seat 2 extends out of the seat surface 21 of the seat 2, and a support foot 3 is connected to the edge of the support frame 1 extending out of the seat surface 21, the top end of the support foot 3 is detachably connected to the support frame 1, and the bottom end is detachably connected to the floor in the cabin.

[0020] Specifically, in the embodiment of the present application, the movable frames 11 are connected by a connecting assembly, and the connecting assembly includes connecting pieces 4 located on both sides of the support frame 1. Each connecting piece 4 is hinged to the side walls of two adjacent movable frames 11, and by flipping the movable frame 11, the spacing between the hinge points on the connecting piece 4 provides the accommodation margin of the cushion 12 when the movable frame 11 is flipped and the movable frame 11 is folded. The support frame 1 is provided with a limiter for limiting the rotation of the movable frame 11, and the limiter is specifically a limit bolt 41. At least two through holes are formed through the connecting piece 4, and a threaded hole adapted to the limit bolt 41 is formed on the side wall of the movable frame 11. When the support frame 1 is rotated to a flat state, the through holes on the connecting piece 4 correspond to the threaded holes on the movable frame 11, and then two limit bolts 41 are passed through the connecting piece 4 and threadedly connected to the two adjacent movable frames 11, so that the relative rotation between the movable frames 11 can be limited.

[0021] An adjusting bolt 31 is rotatably arranged on the bottom wall of the supporting frame 1, a threaded hole adapted to the adjusting bolt 31 is opened at the top of the supporting foot 3, the adjusting bolt 31 vertically passes through and is threadedly connected in the threaded hole, and a hexagonal groove is opened at the bottom end of the adjusting bolt 31 for a hexagonal wrench to rotate the adjusting bolt 31.

[0022] Furthermore, an adjustment block 111 is slidably mounted on the edge of the support frame 1, and the adjustment bolt 31 and the support foot 3 are connected to the adjustment block 111. The position of the support foot 3 can be adjusted by moving the adjustment block 111 to facilitate adjustment of the flatness of the recliner.

[0023] In the embodiment of the present application, a ground support 6 is provided at the bottom of the support foot 3. The ground support 6 is adapted to the slide rail on the cabin floor. The cross section of the slide rail is in an inverted "T" shape, and a number of arc-shaped clearance notches are evenly spaced on both sides of the notch on the top wall of the slide rail. The clearance notches are adapted to the shape of the ground support 6, and the ground support 6 can enter and exit the slide rail. A locking block 61 is also vertically slidably connected above the support foot 3. A locking bolt 62 is vertically penetrated through the locking block 61. After the locking bolt 62 passes through the locking block 61, it is threadedly connected to the ground support 6 on the support foot 3. By tightening the locking bolt 62, the locking block 61 can be pushed downward and pressed against the top wall of the slide rail, and combined with the ground support 6 in the slide rail, the inner top wall of the slide rail is supported and tightened, so that the support foot 3 is effectively fixed on the aircraft floor.
