Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a sitting or lying state switching mechanism. Background Art

[0002] A specific example of an existing chair is the chair with application number CN202220136083.7, which includes a frame and a seat plate mounted on the frame. The frame and seat plate are connected by a connector. The connector includes a first connecting block and a second connecting block. The frame is connected to the first connecting block, and the seat plate is connected to the second connecting block. The first and second connecting blocks are rotatably connected, allowing the front and rear ends of the seat plate to swing up and down relative to the frame. This allows the seat plate to use the connector as a fulcrum, allowing the front and rear ends of the seat plate to swing up and down relative to the frame. When the user leans forward, the front end of the seat plate swings downward under the pressure of the user's body, reducing pressure on the user's inner thighs. When the user leans back, the rear end of the seat plate swings downward under the pressure of the user's body, providing more support for the user's inner thighs. Therefore, the seat plate's inclination can adapt to different user postures, improving user comfort.

[0003] The existing chairs are not provided with components that can facilitate the adjustment of the sitting and lying states, so that they cannot be adjusted according to the user's sitting and lying needs during use, thereby having great limitations during use and failing to meet the needs of customers.
