Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below.

Referring to fig. 1 to 4, a far side airbag bag is installed at the right side of a driver's seat, and includes an airbag bag body 10, a chamber partition 3 is provided at the middle of the airbag bag body, and the chamber partition 3 divides the airbag bag body 10 into an upper chamber 1 and a lower chamber 2. The chamber partition 3 in this embodiment is located at the upper middle position of the airbag body 10, the volume of the upper chamber 1 is smaller than that of the lower chamber 2, and the chamber partition 3 is provided with an air passage 31.

The middle part of the lower chamber 2 is provided with a non-inflating area 6, one side of the lower chamber 2 is provided with an air inlet 7, and the airbag body 10 is provided with a longitudinal pull belt 4 extending from the upper chamber 1 to the air inlet 7 and a transverse pull belt 5 extending from one side of the lower chamber 2 far away from the air inlet 7 to the air inlet 7. In this embodiment, the chamber partition 3 is provided with a first fixing portion 301, the non-inflatable region 6 is provided with a second fixing portion 603 and

third fixing portions

601 and 602, the middle portions of the longitudinal pull straps 4 are respectively connected with the first fixing portion 301 and the second fixing portion 603, and the middle portions of the transverse pull straps 5 are connected with the

third fixing portions

601 and 602. Preferably, the chamber partition 3 is sewn with a sewing thread, the non-inflating region 6 is sewn with a sewing thread, and the first fixing portion 301, the second fixing portion 603, and the

third fixing portions

601 and 602 are cut dividing lines. The lateral pulling strap 5 is inserted into the third fastening 601 and is pulled out of the third fastening 602, so that the lateral pulling strap 5 can be deployed toward the shoulder and chest of the driver during the explosion of the airbag, thereby protecting the shoulder and chest of the driver. The longitudinal pull strip 4 is inserted from the first fastening point 301 and is pulled out from the second fastening point 603, so that the airbag upper chamber 1 is deployed towards the driver's head during the airbag explosion. The non-inflatable region 6 ensures that the shoulder contacts the non-inflatable region 6 when the bag is deployed and no head region is unprotected because the shoulder contacts the bag first. In order to further protect the head, the top of the upper chamber 1 is provided with a head protection section 1a which is bent towards the head of the driver, two sides of the head protection section 1a are connected with two sides of the airbag body 10 through

side drawstrings

801 and 802, and the head protection section 1a is matched with the

side drawstrings

801 and 802, so that the upper chamber 1 of the airbag is more smoothly unfolded towards the head of the driver and protects the head of the driver, and a good protection effect is achieved. The longitudinal drawstring 4, the transverse drawstring 5 and the two

side drawstrings

801 and 802 can effectively control the air bag type, so that the air bag forms a wrapping type shape after being unfolded, and further the optimal protection effect is achieved.

As shown in fig. 5 to 13, the folding manner of the distal airbag includes the following steps:

step Z10, the airbag body of the airbag is well arranged and unfolded on a plane, the drawstring is well arranged and fixed,

step Z20, folding the lower end of the airbag body downwards along the first folding line A in figure 5, folding the folded airbag body edge Z01 to be flush with the air inlet position Z01 of the airbag and to be perpendicular to the connecting line between the two fixing points G01 and G02, the connecting line between the two fixing points G01 and G02 to be parallel to the edge Z06 of the airbag, obtaining the airbag as shown in figure 6,

step Z30, folding the airbag body with the folded lower end as shown in FIG. 6 upwards along a second folding line B, wherein the edge Z03 is parallel to the air inlet Z01 and perpendicular to the line between the two fixed points G01 and G02, to obtain the airbag as shown in FIG. 7,

step Z40, folding the upper end of the airbag body as shown in fig. 7 down along the third folding line C to obtain the airbag as shown in fig. 8,

step Z50, folding the folded-up airbag body of fig. 8 upward along a fourth fold line D, folding the folded airbag with the upper edge Z04 parallel to the lower edge Z05, the left side view after folding being shown as M-view in fig. 9,

step Z60, folding the extra part of the airbag body away from the air inlet end shown in fig. 9 two times downward along the folding line E, F, the folding line E, F is parallel to the edge Z06 of the airbag at the air inlet end, the folded view is shown as the view in fig. 10, which is the view in the direction of N,

step Z70, folding the folded airbag body of fig. 10 away from the air inlet along fold line G, H, I three times upward, wherein the fold line G, H, I is parallel to the edge Z06 of the airbag, the left side view after folding is shown as the O-view in fig. 11,

step Z80, folding the airbag body away from the air inlet along the folding line J once again to complete the folding.

The working principle of the utility model is as follows:

when the automobile is in side collision, the air bag receives a signal, the gas generator starts to act on the air bag, when the air bag is folded, the lower chamber 2 is firstly inflated, the latest unfolding is the folding in the step Z80, and the Z folding ensures that the air bag can be quickly unfolded and quickly breaks through a seat tearing line. Then the gas will shunt a part towards the upper part of the lower chamber 2, a part towards the lower part of the lower chamber 2, at this time, steps 20, 40 and 70 will be unfolded together, the upper end and the lower end of the air bag will be folded in a Z shape, the upper part and the lower part will be unfolded first, and the stability of the whole air bag will be ensured, the folding place will be unfolded slowly, it is ensured that the whole air bag will not be unfolded too fast in the transverse direction, the whole air bag will not be unfolded stably, the last one is folded in a step Z60, at this time, the air bag is basically full, the folding can balance the whole outward force of the air bag, so that the air bag can be contracted fast and inwards.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
