The embodiment of the application provides a steering wheel airbag.
As shown in fig. 1 and 2, a steering wheel airbag is folded and stored in a hub 11 of a steering wheel 1, the airbag is inflatable to an inflated position, and has a main chamber 2 supported by the hub 11, the main chamber 2 in the inflated position has a rear panel 22 facing the steering wheel 1, a support chamber 3 is provided on the rear panel 22, the support chamber 3 has a first end portion 31 communicating with the main chamber 2 and a second end portion 33 at the other end, a through hole 21 communicating with the first end portion 31 is provided on the rear panel 22, after the support chamber 3 extends from the first end portion 31 to the steering wheel 1 side, the support chamber 3 is bent along a middle portion to form a bent portion 32, the second end portion 33 is hermetically fixed to the rear panel 22, and the bent portion 32 abuts against an upper edge of the hub 11 and/or a steering column to support the main chamber 2.
The support chamber 3 with smaller inflation amount and excellent support effect is formed, the support chamber 3 is only supported on the upper edge of the hub 11 and/or the steering column, and the upper edge of the hub 11 and/or the steering column provide support for the support chamber 3, so that the support chamber 3 can support the upper part of the main chamber 2, and the main chamber 2 is prevented from being excessively inclined forwards, and passengers are restrained better. Therefore, the airbag of the present application can be applied to a folded state of a steering wheel, a yoke steering wheel, a folding steering wheel, etc. with an upper rim opening, with a lack of providing a specific steering wheel sufficient support for the upper portion of the airbag. Meanwhile, the airbag of the present application is self-supporting on the steering wheel 1 without depending on the support of other parts such as the instrument panel and the upper rim. The application improves the universality of the design of the steering wheel 1 lacking the upper rim while ensuring the effect of protecting passengers by the steering wheel 1.
The airbag of the present application can also be applied to the steering wheel 1 with a rim on the upper part, namely the airbag of the present application can ensure that the main chamber 2 can be stably supported without depending on the support of the rim on the upper part of the steering wheel 1.
The second end portion 33 of the embodiment of the present application is fixed in a manner that the second end portion 33 is first sealed, and then the sealed second end portion 33 is fixed to the back panel 22 after being flattened; the first end portion 31 is fixed in such a manner that the edge of the first end portion 31 is sewn to the rear panel 22 around the through hole 21. In other embodiments, the second end 33 may be fixed by first closing the edges of the second end 33 to form a flat structure, and then sewing the flat structure on the back panel 22 to close the second end 33 while fixing, or sewing the second end 33 on the back panel 22 in a structure with other shapes to ensure the closing and fixing of the second end 33.
The fixing points of the first end part 31 and the second end part 33 of the support chamber 3 on the rear panel 22 are both located above the upper edge of the hub 11, and the fixing points of the first end part 31 and the second end part 33 of the support chamber 3 on the rear panel 22 are distributed along the contour of the upper edge of the hub 11 and are oppositely arranged with the center of the contour of the upper edge of the hub 11, so that the support chamber 3 can provide more uniform support effect for the main chamber 2 at two sides of the center of the hub 11, the inclination of the main chamber 2 in an off-design range is reduced, and more effective protection is provided for passengers.
More specific arrangements of the fixing points of the first end portion 31 and the second end portion 33 on the back panel 22 may be: the centers of the fixing locations of the first end portion 31 and the second end portion 33 on the rear panel 22 are mirror-symmetrical with respect to a vertical center line passing through the center of the hub 11.
The first end portion 31 is disposed on a side close to a vehicle body side portion of the vehicle with respect to the second end portion 33. The first end part 31 is closer to the outer side of the vehicle, so that the support chamber 3 is preferentially inflated at the initial stage of inflation, and the side of the support chamber 3 close to the first end part 31, namely the side of the support chamber 3 close to the outer side of the vehicle, is preferentially inflated, so that the support chamber 3 can provide a support reaction force obliquely towards the vehicle interior at the initial stage of inflation, and therefore, the main chamber 2 is more strongly supported at the side close to the side part of the vehicle body during the offset collision of the vehicle, and therefore, the occupant is better protected during the offset collision of the vehicle. In the present application, the area of the first end portion 31 is larger than the area of the flat second end portion 33, and the first end portion 31 is thicker than the second end portion 33 after the inflation of the support chamber 3, so that the support chamber 3 having such a structure is advantageous in that the support chamber 3 can provide a support reaction force obliquely in the vehicle interior at the initial stage of the inflation when the offset collision of the vehicle occurs.
As shown in fig. 3, the support chamber 3 of the present application is formed by bending and fixing two ends of a three-dimensional elongated cavity after being inflated in a natural state. Specifically, when the supporting chamber 3 is not constrained in a natural state, the supporting chamber is inflated and expanded to form a three-dimensional strip, the three-dimensional strip can be in various shapes such as a cylinder, an upright post or a cone, the cross section of the three-dimensional strip can also be in a rectangular shape, a triangular shape or an oval shape, the design is specifically carried out according to the profile of the upper edge of the hub 11, the matching of the surface radians of the upper edges of the supporting chamber 3 and the hub 11 in a use state is ensured as much as possible, and the hub 11 can provide better support for the supporting chamber 3.
At least a part of the support chamber 3 extends from the end face of the first end portion 31 toward the steering wheel 1 side in a direction perpendicular to the rear panel 22. Specifically, in this embodiment, when the first end portion 31 is sewn to the back panel 22 and the second end portion 33 which is closed is not fixed, the second end portion 33 is a free end, the extending direction of the support chamber 3 in the inflated state is perpendicular to the back panel 22, before the first end portion 31 is sewn, the end surface of the first end portion 31 is perpendicular to the length direction of the stereoscopic strip, then the end surface of the first end portion 31 is opposite to the back panel 22, and the edge of the first end portion 31 is sewn to the back panel 22, so that the extending direction of the support chamber 3 in the inflated state is perpendicular to the back panel 22 when the second end portion 33 is not fixed; after the three-dimensional strip-shaped bag body is bent, when the second end part 33 is normally fixed on the rear panel 22, after the supporting chamber 3 is inflated, the end part of the supporting chamber 3 adjacent to the through hole 21 is provided with a small segment structure vertical to the rear panel 22, so that the supporting force provided by the supporting chamber 3 faces the main chamber 2 as much as possible, and the supporting effect of the supporting chamber 3 on the main chamber 2 is improved.
The support chamber 3 contacts the upper edge of the hub 11 at the initial stage of inflation, and the support chamber 3 completes inflation in a state of abutting against the upper edge of the hub 11.
As shown in fig. 4 and 5, during the initial inflation (30 ms), the bladder supporting the chamber 31 is positioned to be aligned with the upper edge of the hub 11. This position is critical to properly engage the steering wheel 1 and provide effective restraint. At an inflation time of 40-50ms the support chamber 3 starts to inflate fully against the upper edge of the hub 11 and at an inflation time of 60ms the support chamber 3 completes inflating supporting the upper part of the main chamber 2 preventing excessive forward tilting of the main chamber 2 for better occupant restraint.
As shown in fig. 6, the through hole 21 is provided with a gas check structure, so that the gas in the main chamber 2 forms a unidirectional flow from the main chamber 2 to the support chamber 3. Making it difficult for the gas entering the support chamber 3 to flow back into the main chamber 2. Ensuring that the support chamber 3 has sufficient pressure to provide support to the main chamber 2.
The gas check structure comprises a conical fabric check valve 4 communicated with the through hole 21, the large-diameter end of the fabric check valve 4 is connected with the through hole 21, the fabric check valve 4 extends into the supporting cavity 3 from the position of the through hole 21, and the tail end of the specific fabric check valve 4 extends to the front of the bending point of the supporting cavity 3, so that the normal air outlet of the fabric check valve 4 is ensured.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
