[0031] In summary, the backrest frame assembly 1, the backrest angle adjuster connecting plate 5, the seat cushion frame assembly 2, the support leg assembly 3, and the seat cushion lifting support leg 4 together form a "four-bar" structure.

[0032] When the seat needs to be adjusted to a zero-gravity state, pull the unlocking handle 6. The pull cable on the unlocking handle 6 unlocks the angle adjuster. The backrest frame assembly 1 rotates backward about the angle adjuster on the connecting plate 5 of the angle adjuster as the axis. At the same time, the seat cushion frame assembly 2 moves forward and upward under the combined action of the connecting plate 5 of the angle adjuster and the seat cushion lifting support 4. The connecting plate 5 of the angle adjuster has a stop point to limit the angle adjuster. The angle adjuster has a limiting structure inside to limit the rotation of the angle adjuster. Under the action of the stop point on the connecting plate 5 of the angle adjuster or the internal limiting structure of the angle adjuster, the backrest frame assembly 1 and the seat cushion frame assembly 2 simultaneously reach the position required for the zero-gravity posture, and the entire seat also reaches the zero-gravity seating position. At this time, the backrest frame assembly 1 and the seat cushion frame assembly 2 are both 60° relative to the vertical direction, that is, the included angle between the backrest frame assembly 1 and the seat cushion frame assembly 2 is 120°.

[0033] For further details, please refer to Figure 1 The connecting plate 5 of the angle adjuster has two mounting holes, one large and one small. The large mounting hole is used to connect the angle adjuster, and the small mounting hole is used to connect the seat cushion frame assembly 2.

[0034] In this embodiment, the upper connecting plate 5 of the angle adjuster is provided with two mounting holes, one large and one small. The large mounting hole is used to connect the angle adjuster, and the small mounting hole is used to connect the seat cushion frame assembly 2. The backrest frame assembly 1 is connected to the support leg assembly 3 through the upper connecting plate 5 of the angle adjuster, and the seat cushion frame assembly 2 is connected to the support leg assembly 3 through the seat cushion lifting support leg 4.

[0035] For further details, please refer to Figure 3 and Figure 5 When the backrest frame assembly 1 flips backward, the seat cushion frame assembly 2 moves forward at the same time.

[0036] In this embodiment, when the unlocking handle 6 is pulled, the pull cord on the unlocking handle 6 unlocks the angle adjuster. The backrest frame assembly 1 rotates backward about the angle adjuster on the connecting plate 5 of the angle adjuster as the axis. At the same time, the seat cushion frame assembly 2 moves forward and upward under the combined action of the connecting plate 5 of the angle adjuster and the seat cushion lifting support 4.

[0037] Furthermore, the connecting plate 5 of the angle adjuster is provided with a stop point, which is used to limit the angle adjuster.

[0038] Furthermore, the angle adjuster has an internal limiting structure to restrict its rotation.

[0039] In this embodiment, under the action of the stop point of the connecting plate 5 on the angle adjuster or the internal limiting structure of the angle adjuster, the backrest frame assembly 1 and the seat cushion frame assembly 2 simultaneously reach the position required for zero gravity posture. The stop point prevents the angle adjuster from rotating after reaching a certain angle, and the limiting structure prevents the angle adjuster from continuing to rotate after rotating to a certain angle.

[0040] For further details, please refer to Figure 3 and Figure 5 When the seat reaches the zero-gravity posture position, the included angle between the backrest frame assembly 1 and the seat cushion frame assembly 2 is 120°.

[0041] In this embodiment, the entire seat reaches a zero-gravity seating position. At this time, the backrest frame assembly 1 and the seat cushion frame assembly 2 are both at 60° relative to the vertical direction, that is, the included angle between the backrest frame assembly 1 and the seat cushion frame assembly 2 is 120°.

[0042] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the seat to a zero-gravity state, the unlocking handle 6 is pulled, and the pull cable on the unlocking handle 6 unlocks the angle adjuster. The backrest frame assembly 1 rotates backward about the angle adjuster on the connecting plate 5 of the angle adjuster as the axis. At the same time, the seat cushion frame assembly 2 moves forward and upward under the combined action of the connecting plate 5 of the angle adjuster and the seat cushion lifting support 4. The connecting plate 5 of the angle adjuster is provided with a stop point to limit the angle adjuster. The angle adjuster is provided with a limiting structure inside to limit the rotation of the angle adjuster. Under the action of the stop point of the connecting plate 5 of the angle adjuster or the internal limiting structure of the angle adjuster, the backrest frame assembly 1 and the seat cushion frame assembly 2 simultaneously reach the position required for the zero-gravity posture, and the entire seat also reaches the zero-gravity seating position. At this time, the backrest frame assembly 1 and the seat cushion frame assembly 2 are both 60° relative to the vertical direction, that is, the included angle between the backrest frame assembly 1 and the seat cushion frame assembly 2 is 120°.
