Description

Technical Field

[0001] This disclosure relates to vehicle safety technology. Specifically, this disclosure relates to an airbag for a vehicle. Additionally, this disclosure also relates to a vehicle. Background Technology

[0002] To ensure passenger safety, airbags are typically installed in vehicles to protect passengers in the event of an accident, thereby reducing or preventing injury.

[0003] The airbag seams are the stitching structures used to sew the fabric together to create the airbag chamber. To ensure good airtightness and protective performance, the airbag seams must be securely sewn and undamaged.

[0004] However, vehicles typically contain metal components (such as seatbelt buckles and airbag inflators used in the event of an accident). In certain situations (e.g., while the vehicle is in motion, when the seatbelt is engaged, or when the airbag inflates rapidly), the sharp edges of these metal components may scrape against the airbag seams, damaging them. Such damage can lead to perforation of the airbag, adversely affecting its protective performance. Utility Model Content

[0005] To address the problems existing in the prior art, this disclosure provides a vehicle airbag comprising a main seam and auxiliary seams. By providing auxiliary seams, the main seam can be protected to prevent damage from scratches by metal parts.

[0006] A first aspect of this disclosure provides an airbag for a vehicle, the airbag comprising:

[0007] The main suture is configured to sew together a fabric to construct an airbag chamber;

[0008] An auxiliary suture, configured to protect the main suture, includes a first auxiliary suture and a second auxiliary suture, the first auxiliary suture and the second auxiliary suture being disposed on both sides of the main suture and extending parallel to the main suture along its extension direction.

[0009] In one embodiment of the airbag, the auxiliary suture is provided only in the protected area where the main suture needs to be protected.

[0010] In one embodiment of the airbag, the knitting density of the auxiliary stitches is from 19 mm / 10 stitches to 26 mm / 10 stitches.

[0011] In one embodiment of the airbag, the distance from the first auxiliary stitch to the main stitch is a first distance, the distance from the second auxiliary stitch to the main stitch is a second distance, and the first distance and the second distance are in the range of 0 to 3 millimeters.

[0012] In one embodiment of the airbag, the first distance and the second distance are different from each other.

[0013] In one embodiment of the airbag, the first distance and the second distance are the same as each other.

[0014] In one embodiment of the airbag, the first distance and the second distance are approximately 1 millimeter.

[0015] In one embodiment of the airbag, the auxiliary suture and the main suture are the same suture.

[0016] In one embodiment of the airbag, the main seam is a first main seam, and the airbag further includes a second main seam configured to sew fabric together to form an airbag chamber, wherein the first and second main seams are parallel to each other, and the first main seam is positioned on the side more susceptible to scratches from metal parts compared to the second main seam, a first auxiliary seam is positioned on one side of the first main seam, and the second auxiliary seam is positioned on the other side of the first main seam and between the first and second main seams.

[0017] A second aspect of this disclosure provides a vehicle that includes an airbag according to a first aspect of this disclosure.

[0018] In the technical solutions proposed in various aspects of this disclosure, by setting auxiliary seams for the single main seam or double main seam of the airbag, the main seam can be protected to avoid damage to the main seam due to scratches from metal parts, thereby ensuring good airtightness and protective performance of the airbag.

[0028] To address the aforementioned deficiencies in the prior art, this disclosure provides a safety airbag for vehicles. Embodiments for implementing this disclosure will now be described with reference to the accompanying drawings.

[0029] First Embodiment

[0030] like Figure 1 and Figure 2As shown, a first embodiment of this disclosure provides an airbag for a vehicle. The airbag includes a main seam and auxiliary seams. In the first embodiment, the main seam is configured to sew a fabric fabric together to construct an airbag chamber, and the main seam is configured as a double main seam. That is, the main seam includes a first main seam 1 and a second main seam 2 parallel to each other, wherein the first main seam 1 is positioned on the side more susceptible to scratches from a metal component 100 compared to the second main seam 2 (see [link to documentation]). Figure 2 ).

[0031] The auxiliary suture is configured to protect the first main suture 1 and includes a first auxiliary suture 11 and a second auxiliary suture 12. The first auxiliary suture 11 and the second auxiliary suture 12 are disposed on both sides of the first main suture 1 and extend parallel to the first main suture 1 along its extension direction. Specifically, the first auxiliary suture 11 is disposed on one side of the first main suture 1, and the second auxiliary suture 12 is disposed on the other side of the first main suture 1 and between the first main suture 1 and the second main suture 12. The auxiliary suture and the main suture can use the same suture thread to facilitate the use of the same sewing equipment to sew the auxiliary suture and the main suture.

[0032] like Figure 2 As shown, when the metal component 100 moves along the direction of travel of the main seam that may scrape against the airbag, the metal component 100 will first touch the first auxiliary seam 11 (see...). Figure 2 (See Figure ①). Then, the leading edge of the metal part 100 will be raised due to the suture height of the first auxiliary suture 11, and thus the metal part 100 can smoothly pass over the first main suture 1 without damaging the first main suture 1 (see Figure ①). Figure 2 (See Figure ②). Thereafter, the leading edge of the metal component 100 will maintain a certain height so that the metal component 100 can smoothly pass over the second auxiliary seam 12 and the second main seam 2 (see Figure ②). Figure 2 (See Figure ③). Thus, by setting the first auxiliary seam 11 and the second auxiliary seam 12, the first main seam 1 and the second main seam 2 can be protected from the effects of scratches from the metal part 100.

[0033] Preferably, auxiliary stitches (i.e., first auxiliary stitch 11 and second auxiliary stitch 12) can be provided only in the protected areas where the main stitches (i.e., the first main stitch 1 and the second main stitch 2) need protection. For example, for a target area where the main stitches may be scratched by the metal part 100, a certain safety margin can be added to both sides of the target area along the extension direction of the main stitches, and the area obtained after adding a certain safety margin to the target area can be used as the protected area for providing auxiliary stitches. Typically, this safety margin can be set to 10 to 20 mm. By providing auxiliary stitches only in the protected areas where the main stitches need protection, costs can be further reduced.

[0034] Preferably, the knitting density of the auxiliary stitches can be set to 19 mm / 10 stitches to 26 mm / 10 stitches. Setting the auxiliary stitches with a higher knitting density can further prevent metal parts from scratching the main stitches and causing damage to them.

[0035] like Figure 2 As shown, the distance from the first auxiliary suture 11 to the first main suture 1 is a first distance S1, and the distance from the second auxiliary suture 12 to the first main suture 1 is a second distance S2. Preferably, the first distance S1 and the second distance S2 can be set within the range of 0 to 3 millimeters. Figure 2 As shown, the first distance S1 and the second distance S2 can be set differently from each other. For example, the first distance S1 can be set to approximately 1 mm, and the second distance S2 can be set to approximately 3 mm. Alternatively, the first distance S1 and the second distance S2 can be set to be the same as each other. For example, both the first distance S1 and the second distance S2 can be set to approximately 1 mm. By appropriately setting the first distance S1 and the second distance S2, the auxiliary seam can better protect the main seam, so that even if the movement of the metal part 100 damages the fabric of the airbag, the damaged area will be far away from the main seam, thereby avoiding adverse effects on the airtightness and protective performance of the airbag due to damage to the main seam.

[0036] Second Embodiment

[0037] A second embodiment of this disclosure provides an airbag for a vehicle. The difference between the second and first embodiments is that the main seam is a single seam design. Hereinafter, only the differences in construction between the second and first embodiments will be described. In the second embodiment, components identical to those in the first embodiment will be indicated by the same reference numerals, and their descriptions will be omitted.

[0038] like Figure 3 and Figure 4 As shown, in the second embodiment, the main seam is configured to sew the fabric together to construct the airbag chamber, and the main seam is a single-seam design. That is, the main seam consists only of main seam 1A.

[0039] The auxiliary sutures are configured to protect the main suture 1A and include a first auxiliary suture 11A and a second auxiliary suture 12A. The first auxiliary suture 11A and the second auxiliary suture 12A are disposed on both sides of the main suture 1A and extend parallel to the main suture 1A along its extension direction. The auxiliary sutures and the main suture can use the same suture material, so that the same sewing equipment can be used to sew both the auxiliary sutures and the main suture.

[0040] like Figure 4 As shown, when the metal part 100 moves along the direction of travel of the main seam that may scrape against the airbag, the metal part 100 will first touch the first auxiliary seam 11A (see...). Figure 4 (See Figure ①). Then, the leading edge of the metal part 100 will be raised due to the suture height of the first auxiliary suture 11A, and thus the metal part 100 can smoothly cross the main suture 1A without damaging the main suture 1A (see Figure ①). Figure 4 (See Figure ②). Thereafter, the leading edge of the metal component 100 will maintain a certain height so that the metal component 100 can smoothly pass over the second auxiliary seam 12A (see Figure ②). Figure 4 (See Figure ③). Thus, by setting the first auxiliary seam 11A and the second auxiliary seam 12A, the main seam 1A can be protected from being scratched by the metal part 100.

[0041] Preferably, auxiliary sutures (i.e., first auxiliary suture 11A and second auxiliary suture 12A) can be provided only in the protected areas where the main suture 1A needs protection. For example, for a target area where the main suture 1A may be scratched by the metal part 100, a certain safety margin can be added to both sides of the target area along the extension direction of the main suture 1A, and the area obtained after adding a certain safety margin to the target area is used as the protected area for providing auxiliary sutures. Typically, this safety margin can be set to 10 to 20 mm. By providing auxiliary sutures only in the protected areas where the main suture needs protection, costs can be further reduced.

[0042] Preferably, the knitting density of the auxiliary stitches can be set to 19 mm / 10 stitches to 26 mm / 10 stitches. Setting the auxiliary stitches with a higher knitting density can further prevent metal parts from scratching the main stitches and causing damage to them.

[0043] like Figure 4 As shown, the distance from the first auxiliary suture 11A to the main suture 1A is the first distance S1A, and the distance from the second auxiliary suture 12A to the main suture 1A is the second distance S2A. Preferably, the first distance S1A and the second distance S2A can be set within the range of 0 to 3 mm. Figure 4As shown, the first distance S1A and the second distance S2A can be set differently from each other. For example, the first distance S1A can be set to approximately 1 mm, and the second distance S2A can be set to approximately 2 mm. Alternatively, the first distance S1A and the second distance S2A can be set to be the same as each other. For example, both the first distance S1A and the second distance S2A can be set to approximately 1 mm. By appropriately setting the first distance S1A and the second distance S2A, the auxiliary seam can better protect the main seam, so that even if the movement of the metal part 100 damages the fabric of the airbag, the damaged area will be far away from the main seam, thereby avoiding adverse effects on the airtightness and protective performance of the airbag due to damage to the main seam.

[0044] Embodiments of this disclosure also relate to a vehicle that includes an airbag according to a first or second embodiment.

[0045] As described above, the airbag for a vehicle according to this disclosure includes a main seam and an auxiliary seam. By providing the auxiliary seam, the main seam can be protected from damage due to scratches from metal parts.
