Description

Technical Field

[0001] The utility model relates to the technical field of automobile protective components, in particular to a one-piece safety airbag. Background Art

[0002] Airbags are the most important protective devices inside a car. When a collision occurs, the gas in the generator explodes and quickly fills the airbag through the air inlet, thereby effectively protecting the occupants and avoiding secondary injuries, thereby achieving the purpose of protecting the occupants.

[0003] In the prior art, airbags are sewn together from two or more panels, requiring a large number of stitches. However, the increased number of stitches can easily cause the airbag to rupture at the stitches when subjected to the impact of gas, rendering the airbag ineffective in protecting the occupant. Utility Model Content

[0005] The utility model is achieved through the following technical solutions:

[0006] A one-piece safety airbag comprises an airbag panel, which is folded and sewn with stitches at its edges. A first mounting hole and a second mounting hole for connecting to an outlet end of a gas generator are respectively provided at both ends of the airbag panel. After the airbag panel is sewn, the first mounting hole and the second mounting hole overlap.

[0007] Furthermore, the airbag panel is of an elongated structure, comprising two long sides and two short sides, and the first mounting hole and the second mounting hole are respectively arranged at positions adjacent to the two short sides.

[0008] Furthermore, the suture includes a first suture, a second suture and a third suture, the first suture is configured to be sewn around the circumference of the first mounting hole, the second suture is configured to be sewn along the circumference of the long side, and the third suture is configured to be sewn along the circumference of the short side.

[0009] Furthermore, the airbag panel is provided with an extension portion along the long side.

[0010] Furthermore, a first three-dimensional relief raised indentation or a first three-dimensional relief sunken indentation is provided around the first mounting hole, and correspondingly, a matching second three-dimensional relief raised indentation or a second three-dimensional relief sunken indentation is provided around the second mounting hole.

[0011] Furthermore, the airbag panel is provided with auxiliary folding lines.

[0012] The beneficial effects of the present utility model are as follows: a one-piece safety airbag comprises an airbag panel, wherein the airbag panel is folded and formed by sewing edges with stitches, and the two ends of the airbag panel are respectively provided with a first mounting hole and a second mounting hole for connecting to the air outlet end of the gas generator, and after the airbag panel is sewn, the first mounting hole and the second mounting hole overlap, and by using a one-piece airbag panel instead of the traditional two-piece or four-piece or more panels to sew the airbag, not only the number of stitches is reduced, the production process is simplified, the production cost is reduced, the types of materials of the airbag panel are reduced, and material management is facilitated.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Reference Figures 1 to 3 As shown, a one-piece airbag includes an airbag panel 1, which is folded and sewn with stitches at the edges. The two ends of the airbag panel 1 are respectively provided with a first mounting hole 11 and a second mounting hole 12 for connecting to the outlet end of the gas generator. After the airbag panel 1 is sewn, the first mounting hole 11 and the second mounting hole 12 overlap.

[0020] The utility model adopts a one-piece airbag panel 1 to replace the traditional two or four or more panels to sew the airbag, which not only reduces the number of stitches, simplifies the production process, reduces production costs, reduces the types of materials of the airbag panel 1, and facilitates material management.

[0021] The airbag panel 1 is an elongated structure, including two long sides 13 and two short sides 14. The first mounting hole 11 and the second mounting hole 12 are respectively arranged adjacent to the short sides 14. The stitches include a first stitch 2, a second stitch 3, and a third stitch 4. The first stitch 2 is configured to be sewn around the periphery of the first mounting hole 11, the second stitch 3 is configured to be sewn along the periphery of the long side 13, and the third stitch 4 is configured to be sewn along the periphery of the short side 14.

[0022] The airbag panel 1 is provided with an extension 15 along its long side 13. During sewing, the first mounting hole 11 and the second mounting hole 12 are first aligned. Then, the third stitch 4 is used to sew along the perimeter of the short side 14, forming a cylindrical shape. The extension 15 is then folded over, and the second stitch 3 is used to sew along the perimeter of the long side 13. The provision of the extension 15 ensures that, after the airbag panel 1 is fully sewn and inflated, its perimeter is rounded, eliminating sharp angles. This increases the inflation space and effectively protects the passenger.

[0023] Reference Figure 2 As shown, a first three-dimensional relief convex indentation 17 is provided around the first mounting hole 11, and a second three-dimensional relief convex indentation 18 adapted to the first three-dimensional relief convex indentation 17 is provided around the second mounting hole 12. The width and depth of the second three-dimensional relief convex indentation 18 can be set to be slightly larger than the first three-dimensional relief convex indentation 17. Through the cooperation of the two, the positioning of the first mounting hole 11 and the second mounting hole 12 are completed, ensuring the mutual alignment between the first mounting hole 11 and the second mounting hole 12 and the gas outlet end of the gas generator. The gas generator is clamped between the first mounting hole 11 and the second mounting hole 12, and then sewn with the first stitch 2. During the detonation process of the airbag, since the first mounting hole 11 and the second mounting hole 12 are integrally formed on the airbag piece 1, when the impact force is carried, the impact force is dispersed to the airbag piece 1 to avoid causing the airbag to rupture.

[0024] Similarly, as another embodiment, a first three-dimensional relief concave indentation is provided around the first mounting hole 11 , and a second three-dimensional relief concave indentation adapted to the first three-dimensional relief concave indentation is provided around the second mounting hole 12 .

[0025] The airbag panel 1 is provided with a folding auxiliary line 16. The folding auxiliary line 16 can be provided on the airbag panel 1 by means of colored strokes or indentations, so as to facilitate the flipping and positioning of the airbag panel 1.
