Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a seat with a zero-gravity lying-flat function. Background Art

[0002] With the development of automobiles, interior spaces have become increasingly diverse, and seats are required to fulfill more functions. Reclining and resting in a car has become a popular choice for in-car configurations. Zero-gravity seats offer enhanced comfort and reclining capabilities. These seats, through sophisticated design, combine the principles of zero gravity with automotive seat technology (or home massage chair technology), leveraging ergonomics to give passengers a sense of weightlessness, reminiscent of outer space, allowing them to fully relax and relieve stress.

[0003] To achieve both reclining and lifting functions, zero-gravity chairs require a complex lifting mechanism at the front end. These mechanisms typically consist of multiple components, including a motor, transmission, and support rods. The rear end of the zero-gravity chair also needs to rotate to accommodate different seating positions.

[0004] However, since a zero-gravity seat has a lifting mechanism at the front end, its strength is weaker than that of a general seat, and the rear end needs to rotate, so its rotating structure also requires a certain strength. Therefore, it is necessary to develop a zero-gravity seat with a relatively simple overall structure and sufficient strength to meet usage requirements. Utility Model Content

[0005] The purpose of the utility model is to provide a chair with a zero-gravity lying-flat function, which solves the problems of poor structural strength and complex structure of existing zero-gravity chairs.

[0006] To achieve the above-mentioned purpose, the present invention provides a chair with a zero-gravity lying-flat function, comprising a backrest side panel, a backrest adjustment component and a seat cushion adjustment component;

[0007] The seat cushion adjustment assembly includes a seat frame side panel, a seat cushion rear transverse tube, a front connecting rod and a lifting member. The backrest side panel is connected to the backrest adjustment assembly, the seat frame side panel is connected to the backrest adjustment assembly, the seat cushion rear transverse tube is riveted to the seat frame side panel, the front connecting rod is riveted to the seat frame side panel and is located at one end of the seat frame side panel away from the seat cushion rear transverse tube, and the lifting member is connected to the front connecting rod.

[0008] Wherein, the lifting component includes a lifting motor, a lifting motor mounting bracket and a front lifting link, the lifting motor is mounted on the lifting motor mounting bracket, and the lifting motor mounting bracket is welded to the front lifting link; the front lifting link is connected to the front link by bolts and is located at the end of the front link away from the seat frame side panel.

[0009] Wherein, the lifting component also includes a front lifting angle adjuster and a lifting mounting bracket, the front lifting angle adjuster is welded to the front connecting rod, and the lifting motor drives the front lifting angle adjuster to rotate; the lifting mounting bracket is welded to the front lifting angle adjuster.

[0010] Wherein, the seat cushion adjustment assembly further includes a seat cushion rear mounting bracket, which is welded to the seat cushion rear transverse tube and is located below the seat cushion rear transverse tube.

[0011] The backrest adjustment assembly includes a backrest motor and a backrest angle adjuster. The backrest motor is installed on the backrest side panel. The backrest angle adjuster is welded to the backrest side panel. The backrest motor drives the backrest angle adjuster to rotate.

[0012] Among them, the backrest adjustment assembly also includes a lower backrest connecting plate, which is welded to the backrest adjuster, and the lower backrest connecting plate is connected to the seat frame side plate by bolts, and is located at one end of the seat frame side plate close to the rear cross tube of the seat cushion.

[0013] Among them, the seat with zero-gravity lying-flat function also includes a front cross tube and a leg rest assembly. The front cross tube is welded to the seat frame side panel and is located at one end of the seat frame side panel away from the rear cross tube of the seat cushion; the leg rest assembly is welded to the front cross tube.

[0014] The utility model provides a seat with a zero-gravity lying-flat function, wherein the lifting component drives the front connecting rod to rotate upward, thereby causing the seat frame side panel to rotate around the rear transverse tube of the seat cushion, and the backrest adjustment component drives the backrest side panel to rotate backward, thereby realizing a zero-gravity seat, and vice versa, it returns to a normal use state, with a simpler structure and stronger strength.
