The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 5, Fig. 6; During constituting, the utility model comprises seat back-rest framework 1, the inboard guiding of air bag cloth 6, air bag outside guiding cloth 7, profile hook 8 and bolt assembly 10; The inboard guiding of said air bag cloth 6 is of a size of setting value with air bag outside guiding cloth 7; Both link together with seat back-rest framework 1 by inside edge zone passage bolt assembly 10; Both outer ledges are stitched together through face cover tear line 5 and seat face cover positive 3 and seat face cover lateral surface 4, and seat side air bag device 2 is arranged between air bag inboard guiding cloth 6 and the air bag outside guiding cloth 7.
Referring to Fig. 1, Fig. 2, Fig. 5, Fig. 6; The inboard guiding of air bag during the utility model constitutes cloth 6 middle parts are between seat side air bag device 2 and seat back-rest framework 1; And be provided with airbag apparatus and pass the hole from two of strap bolt coupling; Said air bag outside guiding cloth 7 zone lines encase seat side air bag device 2, and the inside edge vertically is uniformly distributed with one group of profile hook 8, and said profile hook 8 is captiveed joint with seat back-rest framework 1.
Referring to Fig. 5; The inboard guiding of air bag during the utility model constitutes cloth 6 is identical with air bag outside guiding cloth 7 length; Its size value L=190 mm～260 mm; The shape of the position of width and face cover tear line 5, the thickness of seat side air bag device 2 and width, seat back-rest framework 1 adapts, and reserves the 10mm surplus.
Referring to Fig. 5, the profile during the utility model constitutes is linked up with 8 quantity and is no less than three covers, the width B >=50mm of every suit profile hook.
Referring to Fig. 5, bolt assembly 10 quantity during the utility model constitutes are no less than two groups, are positioned at a group of bottom and plant Edge Distance L1=60 mm～80 mm, two pitch of bolts L2=60 mm～80 mm with air bag outside guiding.
Referring to Fig. 8, the inboard guiding of the air bag of the utility model cloth 6 also can encase the seat side air bag device from the front end of backrest skeleton, and the inside edge of air bag outside guiding cloth 7 no longer is provided with the profile hook.
Referring to Fig. 5, Fig. 6, Fig. 7; The principle of work of the utility model is: automobile side impact moment is taking place, and the gas generator in the seat side air bag device 2 detonates, and is filled and expands rapidly by high pressure gas among the airbag 2-1 and launch; Under the inboard guiding of air bag cloth 6 and guiding cloth 7 guiding of the air bag outside; With strong wallop seat face cover tear line is strutted, air bag ejects the easily vulnerable body part to the occupant rapidly, alleviates by car body collision to impact the injury that brings.In this process, the inboard guiding of air bag cloth 6 owing to be connected with skeletal fixation through bolt assembly 10, has been avoided the profile hook shift in position that causes because of the both sides guiding pulling force that cloth bore is different with air bag outside guiding cloth 7; The inboard guiding of air bag cloth 6 passes the place, hole at two and cooperates from strap bolt with the seat side air bag device; The inboard guiding of air bag cloth 6 has determined the direction that air bag ejects with the size of air bag outside guiding cloth 7 simultaneously; This is as the door-plate of two different in width split of fan; After the door-hinge stationkeeping; When certain opening angle, the direction that open on the doorway depends on the width of two door-plates, so air bag can eject along the trajectory of setting.Face cover tear line place suture strength is 1/2nd of other position suture strengths of face cover, has further guaranteed the ejected position of air bag, thereby the safety guard-safeguard effect of air bag is given full play to.Profile hook 8 contacts fixing with seat back-rest framework 1 side plate formation line, advantage is stressed even; But in the later stage of airbag deployment; Along with tearing of seat lateral surface cover; The problem that exists profile hook 8 to break off relations, and the hidden danger of hook unhook has been removed in captiveing joint of two bolt assemblies and seat back-rest framework 1 effectively; Also improve simultaneously the intensity of attachment point end, strengthened the reliability of attachment point.
