Description

Technical Field

[0001] This utility model relates to the field of automotive airbag technology, and in particular to a novel automotive side airbag structure. Background Technology

[0002] As the penetration rate of passenger vehicles increases, people's awareness of automotive safety is also gradually improving. Currently, most vehicles are equipped with airbags to enhance their safety restraint and protection capabilities. Because the intrusion depth and speed in side pole impact tests are relatively high, sufficient vehicle body strength is required, along with sufficiently thick side airbags and a large enough protection area to cover the shoulder, chest, abdomen, and pelvis. However, in actual side pole impact tests, the dummy's arms frequently compress the chest, leading to excessive chest compression.

[0003] To this end, the applicant has invented a novel side airbag structure for automobiles, so that the side airbag can quickly lift the dummy's arm in the event of a side pole collision, thereby avoiding the situation where the dummy's arm compresses the chest and causes the chest compression to exceed the standard.

[0004] Currently, a Chinese patent authorization announcement number CN214001583U discloses a side airbag structure for automobiles. Although this patent can prevent the dummy's arm from squeezing the chest, the structure is complex and cannot guarantee the stable deployment of the airbag.

[0005] In addition, a Chinese patent authorization announcement number CN212556152U discloses a new type of automotive side airbag structure. Similarly, this patent structure is complex and cannot guarantee the stable deployment of the airbag. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a new type of automotive side airbag structure to address the above-mentioned deficiencies and defects of the prior art.

[0007] The technical problem to be solved by this utility model can be achieved by the following technical solution:

[0008] A novel automotive side airbag structure includes an airbag body installed on the side of the car seat and a gas generator disposed on the airbag body for inflating the airbag body. The structure is characterized by further including a root strap fixed to the inner and outer sides of the airbag body, a chest step located at the occupant's chest position, and a shoulder strap located at the occupant's shoulder pivot position.

[0009] In a preferred embodiment of this utility model, the root pull strap is sewn to the inner and outer sides of the air bag body and there is a misalignment difference. The length of the root pull strap is the same as the width of the air bag body, and the width of the air bag body is greater than the misalignment difference.

[0010] In a preferred embodiment of the present invention, the root pull strap is provided with several waist-shaped holes for gas to pass through, and the several waist-shaped holes are arranged at intervals along the length direction of the root pull strap.

[0011] In a preferred embodiment of this utility model, the air bag body is arranged in a butterfly shape, and an air inlet is provided on the air bag body.

[0012] In a preferred embodiment of the present invention, the airbag body includes an inner airbag sheet near the passenger side and an outer airbag sheet near the vehicle door side. The periphery of the inner airbag sheet and the periphery of the outer airbag sheet are sewn together to form an inflation chamber between them.

[0013] In a preferred embodiment of the present invention, an exhaust hole is provided on the outer sheet or the inner sheet of the air bag.

[0014] In a preferred embodiment of the present invention, an exhaust hole reinforcing ring is provided on the inner side of the outer or inner sheet of the air bag and at the exhaust hole.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: First, the presence of the staggered root strap allows control over the direction of airbag deployment, ensuring the airbag unfolds along the occupant's side and maintaining stability during deployment. Second, the presence of the chest step ensures greater thickness of the occupant's chest, facilitating chest pressure adjustment through the vent. Furthermore, when the occupant compresses the airbag, the chest step allows the occupant's arm to rotate upwards along the shoulder axis. Third, the presence of the shoulder strap makes its thickness smaller than that of the chest and abdomen, facilitating rapid shoulder positioning of the airbag and enabling shoulder axis rotation. Additionally, the folding direction of this utility model is generally towards the occupant's side, and the unfolding direction is stable and controllable. The upper end of the airbag unfolds towards the vehicle door, effectively preventing the upper end of the airbag from striking the occupant's arm and preventing the arm from turning outwards. Moreover, the overall folding method is simple, without oblique folds, and the folding thickness of each part is relatively uniform, facilitating automation. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] See Figures 1 to 4 The illustration shows a novel side airbag structure for automobiles, comprising an airbag body 100 mounted on the side of the vehicle seat and a gas generator 200 disposed on the airbag body 100 for inflating the airbag body 100. In this embodiment, the airbag body 100 is arranged in a butterfly shape, and an air inlet 110 is provided on the airbag body 100. Specifically, the airbag body 100 is also provided with a gas generator mounting hole for mounting the gas generator 200 and screw holes for fixing the gas generator 200 by bolt assembly.

[0023] It also includes a root strap 300 fixed to the inner and outer sides of the airbag body 100, a chest step 400 located at the occupant's chest, and a shoulder strap 500 located at the occupant's shoulder pivot. When the airbag body 100 is inflated and deployed, the presence of the misaligned root strap 300 controls the direction of deployment of the airbag body 100, allowing it to deploy along the occupant's side and maintaining stability during deployment. The presence of the chest step 400 allows the occupant's arm to be raised and rotated upwards along the shoulder pivot when the airbag is squeezed. The presence of the shoulder strap 500 makes the shoulder thickness smaller than the chest and abdomen thickness, facilitating the rapid positioning of the airbag body 100's shoulder and promoting the rotation of the shoulder strap 500 pivot.

[0024] The root pull strap 300 is fixed at a lower position inside the air bag body 100 and a higher position near the outer side of the air bag body 100. There is a misalignment difference between the inner and outer positions of the root pull strap 300 sewn into the air bag body 100. The length of the root pull strap 300 is the same as the total width of the air bag body 100, and the width of the air bag body 100 is slightly larger than the misalignment difference. In this embodiment, the root pull strap 300 has several waist-shaped holes 310 for gas to pass through. The several waist-shaped holes 310 are arranged at intervals along the length direction of the root pull strap 300, and the inflation speed of the air bag body's inflation chamber can be adjusted by adjusting the size and position of the waist-shaped holes 310. The chest step 400 protects the occupant's chest. Since the inner airbag panel 100a of the airbag body 100 is longer than the outer airbag panel 100b, the excess fabric of the inner airbag panel 100a is folded once, making its outer contour match the outer airbag panel 100b. The inner airbag panel 100a is then sewn to the outer airbag panel 100b along its edge. After inflation, this fold forms a step surface, which is the chest step 400, and it is thicker at this point. Furthermore, this step surface is wider in the forward direction and narrower in the rear direction, making the front airbag body 100 thicker and the rear airbag body 100 thinner, resulting in better arm-raising ability. The shoulder straps 500 are located at the occupant's shoulder pivot point, with one or two straps used to control the thickness of the occupant's shoulder area.

[0025] The airbag body 100 includes an inner airbag sheet 100a near the occupant and an outer airbag sheet 100b near the door. The periphery of the inner airbag sheet 100a and the periphery of the outer airbag sheet 100b are sewn together to form an inflation chamber between them. In this embodiment, the inner airbag sheet 100a and the outer airbag sheet 100b are not bilaterally symmetrical; the inner airbag sheet 100a has an additional folded area 1a compared to the outer airbag sheet 100b. Specifically, after the folded area 1a of the inner airbag sheet 100a is folded, the front and rear ends of the inner airbag sheet 100a are sewn to the outer airbag sheet 100b. This folded area 1a forms a crease on the outside of the airbag body. When the airbag body is inflated, this crease forms a relatively thick step, which is a chest step 400.

[0026] Furthermore, an exhaust hole 120 is formed on the outer sheet 100b or the inner sheet 100a of the air bag. An exhaust hole reinforcing ring 121 is provided on the inner side of the outer sheet 100b or the inner sheet 100a, located at the exhaust hole 120. The exhaust hole reinforcing ring 121 improves the structural strength at the exhaust hole 120, preventing the sheet at the exhaust hole from cracking due to excessive exhaust pressure. Specifically, in this embodiment, the exhaust hole 120 is formed on the outer sheet 100b of the air bag.

[0027] The sewing sequence of this utility model is as follows:

[0028] Step 1: The structure of the air inlet 110 of the air bag body 100 is sewn in the conventional way, which will not be described in detail here;

[0029] Step 2: Sewing the root pull strap 300. Align the upper inner positioning point 31 and lower inner positioning point 32 of the root pull strap 300 with the corresponding upper inner positioning point 11a and lower inner positioning point 12a on the inner panel 100a of the air bag. Sew the root pull strap 300 to the inner panel 100a of the air bag along the inner edge 33. The sewing effect is as follows: Figure 1 'a' in 'a';

[0030] Step 3: Align the upper outer positioning point 34 and lower outer positioning point 35 of the root pull strap 300 with the corresponding upper outer positioning point 11b and lower outer positioning point 12b on the outer piece 100b of the air bag. Sew the root pull strap 300 to the outer piece 100b of the air bag along the outer edge 36. The sewing effect is as follows: Figure 1 b;

[0031] Step 4: Sewing the chest step 400: Align the line connecting the upper positioning point 13a and the lower positioning point 14a of the inner air bag piece 100a with the line connecting the upper positioning point 15a and the lower positioning point 16a of the inner air bag piece 100a, fold it in half along the middle, and the crease after folding forms a step surface. This step surface is the chest step on the outside of the air bag body 100.

[0032] Step 5: Sewing the shoulder strap 500. Sew one end 51 of the shoulder strap 500 to the shoulder position of the inner piece 100a of the air bag, and sew the other end 52 of the shoulder strap 500 to the shoulder position of the outer piece 100b of the air bag. The number of shoulder straps can be 1 or 2.

[0033] Step 6: Align the outer edge 10a of the inner air bag piece 100a with the outer edge 10b of the outer air bag piece 100b, and sew them together.
