[0042] Figure 4 This illustration shows the structure of an airbag in its deployed state according to an embodiment of the present invention. Figure 5 Indicate Figure 4 Cross-sectional structure of the central airbag. Figure 6 and Figure 7 The diagrams illustrate the cross-sectional structures of two other airbags in the deployed state in the embodiments of this utility model. Figure 8The utility model discloses a kind of airbag bag in the contact state of collision test with human chest. In combination Figures 4 to 8 As shown, the airbag bag 400 provided by the utility model has a first area 410 corresponding to the chest 110 of the protected object in the unfolded state, and the first area 410 is provided with a plurality of first pull tapes 500. The plurality of first pull tapes 500 limit the ejection distance of the first area 410 and cause the first area 410 to form a plurality of recesses.

[0043] The airbag bag 400 of the utility model is provided with a plurality of first pull tapes 500 in the first area 410 corresponding to the chest 110 of the protected object, which can effectively limit the ejection distance of the first area 410 and greatly improve the impact and compression of the airbag bag 400 on the chest 110 of the human body in a collision accident. The plurality of first pull tapes 500 also cause the first area 410 to form a plurality of recesses, i.e., a segmented recess structure, which can improve the matching degree of the airbag bag 400 with the chest 110 of the human body. On the one hand, the chest 110 of the human body is appropriately avoided to reduce the impact on the chest 110 of the human body, and on the other hand, the contact area with the chest 110 of the human body is increased to reduce the contact degree, thereby reducing the compression on the chest 110 of the human body. Furthermore, the structure with the appropriate recess in the middle and the relatively bulging edges can contain the chest 110 to prevent slipping and minimize the harm to the chest 110 of the human body, thereby effectively protecting the protected object.

[0044] The number of first pull tapes 500 can be set as needed and is at least two to effectively limit the ejection distance of the first area 410 and cause the first area 410 to form a segmented recess structure.

[0045] In some embodiments, the first ends of the plurality of first pull tapes 500 are respectively connected to different positions on the surface of the airbag bag in the first area 410, and the second ends are connected to the steering wheel or instrument panel. That is, the first pull tapes 500 form longitudinal pull tapes extending in the thickness direction of the airbag bag 400, and the two ends of the first pull tapes 500 are respectively connected to the steering wheel / instrument panel and the surface of the airbag bag in the first area 410, thereby effectively limiting the ejection distance of the first area 410, controlling the unfolding thickness of the airbag bag 400, and causing the first area 410 to form a segmented recess structure.

[0046] In some embodiments, as shown in Figure 5 and Figure 6 the second ends of the plurality of first pull tapes 500 are commonly connected to the same position of the steering wheel or instrument panel; or, as shown in Figure 7 the second ends of the plurality of first pull tapes 500 are respectively connected to different positions of the steering wheel or instrument panel.

[0047] In some embodiments, as shown in Figure 6As shown, the plurality of first pull straps 500 includes a first heel pull strap 500a and a plurality of first branch pull straps 500b, the first heel pull strap 500a extends into the airbag pocket 400 from the steering wheel or instrument panel, and branches into the plurality of first branch pull straps 500b, which are respectively connected to different positions on the airbag pocket surface of the first region 410.

[0048] In the above embodiments, in the deployed state, the first region 410 is distributed below the central region of the airbag pocket 400. Among them, referring to Figure 8 As shown, in the deployed state, the central region of the airbag pocket 400 corresponds to the neck of the protected object; the first region 410 below the central region corresponds to the chest 110 of the protected object. Along the longitudinal direction "Z" of the airbag pocket 400 from the top of the airbag pocket 400: the central region of the airbag pocket 400 is located in the position region of 45% to 55% of the airbag pocket surface; the specific position of the central region can be determined according to the vehicle type, configuration and other parameters. For example, if the central region is located in the position region of 45% to 50% of the airbag pocket surface, then the first region 410 is located in the position region below 50% of the airbag pocket surface; for example, if the central region is located in the position region of 47% to 52% of the airbag pocket surface, then the first region 410 is located in the position region below 52% of the airbag pocket surface; and so on.

[0049] Further, the first pull strap 500 is sequentially distributed along the longitudinal direction of the airbag pocket 400 on the airbag pocket surface of the first region 410. In some cases, the first pull strap 500 equally divides the first region 410 into a plurality of recesses, for example, the first pull strap 500 can equally divide the first region 410 into three recesses.

[0050] In some embodiments, in the case where the first pull strap 500 includes two: along the longitudinal direction of the airbag pocket 400, from the top of the airbag pocket 400, the two first pull straps 500 are respectively distributed in the position region of 55% to 70% and the position region of 65% to 85% of the airbag pocket surface. The specific position of the first pull strap 500 can be determined according to the vehicle type, configuration and other parameters. For example, referring to Figure 8 As shown, along the longitudinal direction "Z" of the airbag pocket 400 from the top of the airbag pocket 400: the upper first pull strap 500 is distributed at the position of 65% of the airbag pocket surface, and the lower first pull strap 500 is distributed at the position of 75% of the airbag pocket surface, but not limited thereto.

[0051] In the above embodiments, in combination with Figures 4 to 8 As shown, the plurality of first pull straps 500 configured by the first region 410 divides the first region 410 into a multi-segment recess structure, for example Figures 5 to 8The first area 410 is divided into a three-section recess structure by two first pull tapes 500, so that the thickness and shape of the first area 410 are accurately adjusted, the matching degree of the first area 410 with the chest 110 of the human body is greatly improved, the contact area is increased, the contact degree is reduced, and the damage caused by the impact and compression of the airbag bag 400 on the chest 110 is reduced.

[0054] The number of second pull tapes 600 can also be set as needed, for example Figure 5 One second pull tape 600 is illustrated, Figures 6 to 11 A plurality of (two) second pull tapes 600 are illustrated to appropriately limit the ejection distance of the second area 420 and make the second area 420 form a segmented recess structure.

[0057] In this way, the second pull tape 600 forms a longitudinal pull tape extending along the thickness direction of the airbag bag 400, the two ends of the second pull tape 600 are respectively connected to the steering wheel / instrument panel and the airbag bag surface of the second region 420, thereby effectively limiting the ejection distance of the second region 420, controlling the deployment thickness of the airbag bag 400, and making the second region 420 form a sectional concave structure.

[0058] The second region 420 is divided into a sectional concave structure by the plurality of second pull tapes 600, for example Figures 6 to 11 The second region 420 is divided into a three-section concave structure by two second pull tapes 600, as shown in FIG. 8, so as to accurately adjust the thickness and shape of the second region 420, thereby greatly improving the matching degree of the second region 420 and the head 120 of the human body, increasing the contact area and reducing the contact degree, thereby reducing the damage caused by the impact and compression of the airbag bag 400 on the head 120, and in the offset collision, the risk of lateral displacement of the head 120 is also reduced.
