Specific embodiment
As shown in Fig. 2, air bag double cavity structure airbag of the present invention, the airbag body 1 including double cavity structure.It is described
Airbag body 1 supports chamber 101 and airbag protection chamber 102 to constitute by airbag.
As shown in Fig. 3, Fig. 7, airbag support chamber 101 is sutured by bag webs 101a.First by the bag webs 101a right
Then doubling at broken line L is sutured along periphery of the sewing thread stitching M to bag webs 101a, form airbag and support chamber.The airbag
It supports chamber 101 to be equipped with two air guide weakened line 101b on bag webs 101a, forms two air guide weakening region 101A.The airbag branch
Support chamber 101 is additionally provided with generator mounting hole 101c on bag webs 101a.
As shown in Fig. 4, Fig. 5, Fig. 6 and Fig. 8, airbag protection chamber 102 is sutured by enclosing piece 102a and 2 lateral plate 102b.
Two A side seams for enclosing piece 102a for described first are closed, then by the periphery of two lateral plate 102b respectively with the B side seam of enclosing piece 102a
It closes, forms airbag and protect chamber 102.It is equipped with two gas ports 102c, the gas port 102c on enclosing piece 102a and air guide weakens
Area's 101A shape is consistent and position is corresponding.The airbag protection chamber 102 designs on 2 lateral plate 102b gas vent 102d.
As shown in figs. 2,7 and 8, chamber 101 and airbag protection chamber 102 is supported to suture airbag.The suture
The air guide periphery weakening region 101A that air guide weakened line 101b is formed at the two of chamber 101 is supported to protect chamber 102 with airbag for airbag
Fig. 7, Fig. 8 sewing thread stitching N are seen in two peripheries gas port 102c.It is stitched into airbag support chamber 101 and airbag protection chamber 102
Complete airbag.
As shown in figure 9, airbag support chamber 101 and airbag protection chamber 102 between suture can airbag support chamber 101 with
Airbag protection chamber 102 is sutured before suturing.The suture way are as follows: to bag webs 101a and enclosed along sewing thread stitching N first
Piece 102a is sutured, and then supports chamber 101 and the sewing method of airbag protection chamber 102 to be stitched into respectively by the airbag of front again
Airbag supports chamber 101 and airbag to protect chamber 102, forms complete airbag.
As shown in figs. 1,7 and 8, the safe automobile air bag two-chamber being installed at roof of the vehicle occupant side front beam 5
Structure airbag.Since airbag support chamber 101 is equipped with air guide weakened line 101b, after the detonation of gas generator 6, gas occurs
The gas that device 6 generates is first filled with airbag support chamber 101, and airbag support chamber 101 is made to be unfolded along automobile front windshield 4 and be supported on vapour
