Problems solved by technology

[0003] The existence of the assembly structure of the driver's airbag logo will cause the airbag to lift up the logo area of ​​the door cover after the assembly of the airbag and the door cover, resulting in appearance defects of the airbag
The main reason for the top door cover of the air bag is that the current PET air bag has a large resilience. The traditional air bag structure adopts an external dust cover structure. After folding, the dust cover is reduced to restrict the resilience of the folded bag, which will increase the number of employees operation difficulty and labor intensity, and reduce production tact; such as figure 1 As shown, when the space of the air bag is narrow, the air bag folding module 10 will generate an upward ejection force on the logo 11 of the door cover 12, thereby causing appearance defects

Embodiment 1

[0026] see figure 2 , the present invention is a driver's airbag, comprising an upper main sheet, a lower main sheet, a drawstring and a dust cover, such as Figure 4-5 As shown, the shapes of the upper main piece 1 and the lower main piece 2 are circular, and the outer circle of the upper main piece 1 and the outer circle of the lower main piece 2 are connected by double-needle chain stitches, and the upper main piece 1 is guaranteed Parallel to the lower main sheet 2. The upper main piece 1 and the lower main piece 2 are connected at 360° by a double-needle chain stitching process to form the protective cavity of the airbag.

[0027] A drawstring and a dust cover 5 are arranged between the upper main piece 1 and the lower main piece 2 . One end of the dust cover 5 is stitched with the inner side of the corolla area of ​​the upper main sheet 1, and the other end of the dust cover 5 is in a free state, and is used as a normal dust cover function: the other end of the dust c...

Embodiment 2

[0034] see Figure 10 , in this example, only one set of pull straps is used, including an upper pull strap 3 and a lower pull strap 4 . The circular area at the end of the upper pull strap 3 is located inside the corolla area of ​​the upper main piece 1, the end of the lower pull strap 4 is located inside the lower main piece 2, the central hole of the lower pull strap 4 coincides with the central hole of the lower main piece 2, and the upper pull strap 3 and the other end of the pull-down strap 4 are sewn together, and the two upper pull-up straps 3 are connected with the two lower-down straps 4 at the first place to form a closed circle.

Abstract

The invention relates to the technical field of automobile passive safety, in particular to a safe air bag for a driver. The safe air bag comprises an upper main piece, a lower main piece, a pulling strip and a dust prevention cover. The upper main piece is in sewing connection with the lower main piece along the outer contours. The pulling strip and the dust prevention cover are arranged between the upper main piece and the lower main piece. One end of the dust prevention cover is sutured on the inner side of a corolla area of the upper main piece. After penetrating through a holding annular hole of the lower main piece, the other end of the dust prevention cover covers the outside of a folding bag of the upper main piece and the lower main piece. The dust prevention cover generates downward tensile force on a corolla area of the folding bag. The corolla area of the folding bag is downwards concaved to form a company mark assembling space. Compared with the prior, the safe air bag is simple in structure, high in reliability and controllable in cost; the corolla area of the air bag folding bag is tightened from the interior of the air bag, and a pit is formed, so that the space is reserved for a company mark; the problem that a company mark appearance has defects due to the fact that a door cover company mark area is jacked up by an existing air bag is solved; meanwhile, the member protection performance of the safe air bag for the driver and the cost performance of parts are ensured.

Description

technical field [0001] The invention relates to the technical field of automobile passive safety, in particular to a driver's safety airbag. Background technique [0002] With the intensifying competition between domestic and foreign automakers in the Chinese auto market, and the increasingly rational view of Chinese consumers on auto consumption, the market has increasingly stringent requirements on the cost performance and appearance of auto parts. As an important part of the driver's airbag, the airbag plays a decisive role in the occupant protection function of the airbag. [0003] The existence of the assembly structure of the driver's airbag logo will cause the logo area of ​​the door cover to be lifted up by the air bag after the air bag and door cover are assembled, resulting in appearance defects of the airbag. The main reason for the top door cover of the air bag is that the current PET air bag has a large resilience. The traditional air bag structure adopts an ex...
