[0028] The following further clarifies the present utility model in conjunction with the drawings and detailed implementation manners. It should be understood that the following detailed implementation manners are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0029] Please refer to Figures 1-6 , an automotive seat assembly, including a seat 1 and a backrest 2 rotatably connected to the seat 1. The seat 1 and the backrest 2 are rotatably connected through a rotating seat 14, and the included angle between the seat 1 and the backrest 2 is adjustable. The two sides of the backrest 2 are provided with arc-shaped extensions that semi-wrap the passenger's body to enhance the lateral support of the body. A pressure sensor is provided on the top of the seat 1 to detect whether there is someone sitting. The two sides of the seat 1 are bent upward respectively. A first insertion strip 4 is inserted into each side of the seat 1, and each first insertion strip 4 is rotatably connected to a rotating connection strip 5, and each rotating connection strip 5 is fixedly connected to an elastic band 6. The elastic band 6 is made of a flexible material and its length can be elastically adjusted. One end of each elastic band 6 away from the first insertion strip 4 is fixedly connected to a second insertion strip 7, and the second insertion strip 7 is inserted into the bottom of the seat 1. Each elastic band 6 wraps around the adjacent bent part of the seat 1. An airbag 9 is supported on each bent part of the seat 1, and each airbag 9 is clamped between the seat 1 and the elastic band 6. When the two airbags 9 are inflated, they push the elastic bands 6 to wrap around the passenger's legs together. A connecting frame 13 is fixedly connected to the bottom surface of the seat 1, an inflator pump 12 is fixedly installed on the top of the connecting frame 13, and the connecting pipe of the airbag 9 is communicated with the inflator pump 12. The inflator pump 12 is used to inflate and deflate the airbag 9.

[0030] When in use, both the seat 1 and the backrest 2 are covered with a soft outer cover, and the elastic bands 6 are also covered, so as to enhance the comfort of the passenger when sitting.

[0031] The airbag 9 is composed of a main chamber 901 and a number of horizontally stacked stacking chambers 902, and the stacking chambers 902 face the elastic band 6. When the airbag 9 is inflated, the main chamber 901 bulges, and the number of horizontally stacked stacking chambers 902 horizontally extend and bulge, enhancing the pressure on the legs of the passenger, making the wrapping of the passenger's legs more stable. Each elastic band 6 is bonded with a pressure detection band 8 with one side facing the human leg, and the other side of the pressure detection band 8 faces the adjacent stacking chamber 902. The pressure detection band 8 is made of a flexible material and is internally embedded with a pressure sensor, which is used to detect whether the airbag 9 and the elastic band 6 wrap the legs of the passenger with an appropriate pressure, and the magnitude of the wrapping pressure is obtained from specific experiments.

[0032] The pressure sensor on the seat 1, the pressure sensor on the pressure detection band 8, and the air pump 12 are connected to the same control board for collaborative control.

[0033] Each first insert 4 is threadedly connected with a first bolt 10, and the first bolt 10 passes through the seat 1. Each second insert 7 is threadedly connected with a second bolt 11, and the second bolt 11 passes through the seat 1. Fixing with the first bolt 10 and the second bolt 11 reduces the risk of the first insert 4 and the second insert 7 slipping during use.

[0034] A lifting chair pillow 3 is installed at the top of the backrest 2. The lifting chair pillow 3 includes: a mounting seat 301 fixedly connected to the side wall of the backrest 2. The mounting seat 301 is slidably inserted with a chair pillow head 304, and the mounting seat 301 is slidably inserted with a one-way clamping block 302, and the one-way clamping block 302 is provided with one-way clamping teeth for preventing falling. The chair pillow head 304 is provided with a toothed plate adapted to the one-way clamping teeth. The back of the one-way clamping teeth of the one-way clamping block 302 is fixedly connected with a spring 303, and the spring 303 is fixedly connected with the mounting seat 301. The one-way clamping block 302 is fixedly connected with two springs 303, and the two springs 303 are distributed at both ends of the one-way clamping teeth. The spring 303 pushes the one-way clamping block 302 towards the chair pillow head 304. Due to the setting of the one-way clamping teeth, the chair pillow head 304 can be directly lifted to adjust the height of the chair pillow head 304. When it is necessary to lower the chair pillow head 304, the one-way clamping block 302 is pulled away from the toothed plate of the chair pillow head 304, so that the chair pillow head 304 can slide freely. After the adjustment is completed, the one-way clamping block 302 is released, and under the elastic force of the spring 303, the one-way clamping teeth of the one-way clamping block 302 clamp the toothed plate of the chair pillow head 304.

[0035] Working principle:

[0036] When a passenger sits on the seat 1, the pressure sensor on the seat 1 detects the presence of a person, and the air pump 12 inflates the airbag 9, enabling the airbag 9 to be connected to the elastic band 6 to wrap around the passenger's legs from both sides, reducing the lateral slippage of the passenger during a vehicle turn. At the same time, several horizontally stacked stacking cavities 902 expand horizontally, enhancing the pressure on the passenger's legs and making the wrapping of the passenger's legs more stable. The pressure detection belt 8 detects that the pressure reaches the predetermined pressure, and the air pump 12 stops inflating, thus adapting to passengers of different body sizes. When the passenger gets off the vehicle, the pressure sensor detects the absence of a person, and the air pump 12 releases a part of the gas from the airbag 9 to facilitate the passenger to sit on the seat 1 again;

[0037] When adjusting the chair headrest 304 upward, directly lift the chair headrest 304 upward to the appropriate position. Under the elastic force of the spring 303, the one-way cogs of the one-way clamping block 302 engage with the toothed plate of the chair headrest 304; when it is necessary to lower the chair headrest 304, pull the one-way clamping block 302 away from the toothed plate of the chair headrest 304, enabling the chair headrest 304 to slide freely. After the adjustment is completed, release the one-way clamping block 302, and under the elastic force of the spring 303, the one-way cogs of the one-way clamping block 302 engage with the toothed plate of the chair headrest 304.

[0038] It should be noted that the above content only illustrates the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. For those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements all fall within the protection scope of the claims of the present invention.
