Technical Field

[0001] The utility model relates to the technical field of foldable seats, in particular to a foldable gas-assisted injection molding seat. Background Art

[0002] A chair is a kind of seat with a backrest and sometimes armrests. When using the existing foldable injection-molded chair, due to the structure of the human body, it is necessary to purchase a lumbar pad to be placed between the human body and the chair to provide support for the human body, so as to alleviate the discomfort caused by long-term use of the chair. However, the purchased lumbar pad cannot be used by everyone, which will greatly reduce the comfort of the chair. Therefore, we have launched a new foldable gas-assisted injection-molded chair.

[0006] Preferably, the lumbar support mechanism includes four airbags, and connecting hoses are fixedly connected to the left sides of the outer surfaces of the lower two airbags and the right sides of the outer surfaces of the upper two airbags. The ends of the four connecting hoses are fixedly connected to micro air pumps, and the rear ends of the micro air pumps are fixedly connected to solenoid valves.

[0007] Preferably, the lumbar support control key is electrically connected to the lumbar support mechanism.

[0008] Preferably, the four air bags are equidistantly distributed up and down and are all located at the lower inner side of the backrest, and the four micro air pumps are equidistantly distributed left and right and are all located at the upper inner side of the backrest.

[0009] Preferably, the four connecting hoses are all located inside the backrest, and the four micro air pumps all correspond to the positions of the vents.

[0010] Preferably, the four micro air pumps are all electrically connected to the lumbar support control key.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, a lumbar support mechanism is provided on the lower side of the backrest of the chair. When a person uses the chair, the lumbar support control key in the device can control the four air bags in the lumbar support mechanism according to the person's body structure, so that the four air bags can fit the waist of the user according to the user's control, so that the person can reduce the discomfort when using the device for a long time, making the device more comfortable to use;

[0013] 2. In the utility model, by arranging an air vent at the rear part of the backrest of the seat, the lumbar support mechanism can be better ventilated when the device is used to operate the lumbar support mechanism, thereby preventing the micro air pump in the lumbar support mechanism from being damaged due to blockage that causes the inability to complete air intake or exhaust. At the same time, by arranging two cotton blocks on the upper part of the seat cushion and the front part of the backrest, when a human body uses the seat, the four cotton blocks can "wrap" the human body in the seat, which can greatly improve the comfort of use of the seat.
