The specific embodiment
Example 1:
As depicted in figs. 1 and 2, the present invention has a module carrier 5, on module carrier 5, be provided with gas generator 4, airbag 1, in airbag 1, be vertically arranged with mediastinum sheet 8, by mediastinum sheet 8 airbag 1 is divided into first air chamber 101 and second air chamber 102, first air chamber 101 is positioned at airbag 1 rear portion and corresponding with gas generator 4 positions, second air chamber 102 is positioned at first air chamber, 101 fronts, in first air chamber 101, be provided with trabeculae 2, described trabeculae 2 two ends are connected with mediastinum sheet 8 with airbag 1 respectively, by trabeculae 2 first air chamber 101 is divided into plenum chamber 101a and last plenum chamber 101b down, on trabeculae 2, be provided with deflation hole 201, will descend plenum chamber 101a and last plenum chamber 101b to be communicated with by deflation hole 201.On mediastinum sheet 8, be provided with deflation hole 801, lower chamber 101b be communicated with second air chamber 102 by deflation hole 801.The material identical (also can be different) of trabeculae 2, mediastinum sheet 8 and airbag 1.
When the collision of vehicle producer sufficient intensity, gas generator 4 charges into gas in the airbag 1.Gas at first enters among the lower chamber 101a, then enters among the upper chamber 101b, enters at last in the air chamber 102.The whole expansion process of airbag 1 is to launch to windshield 3 or airbag 1 top earlier, then carries out the expansion of airbag 1 bottom, promptly launches downwards.If the occupant is OOP position occupant 7, because airbag 2 upwards launches earlier, insufficient pressure in the airbag 1 so that the occupant be moved, when airbag 1 continues to launch downwards, be that gas is when entering in the air chamber 102, because OOP position occupant 7 has been wrapped in interior location (as shown in Figure 1) by airbag 1 at this moment, airbag 1 can form the pressure to it at the occupant back side, make firm being wrapped in the airbag 1 of occupant, so both prevented that OOP position occupant 7 heads from bumping against instrument carrier panel 6, avoided again because the additional injury that airbag deployment causes OOP position occupant 7.If the occupant is normal position occupant 7 ', after gas passes through three air chambers in the airbag 1, form an airbag shape (as shown in Figure 2) of launching fully, realize protection to the normal position occupant.
Example 2:
As Fig. 3, shown in Figure 4, the present invention has a module carrier 5, on module carrier 5, be provided with gas generator 4, airbag 1, in airbag 1, be vertically arranged with mediastinum sheet 8, by mediastinum sheet 8 airbag 1 is divided into first air chamber 101 and second air chamber 102, first air chamber 101 is positioned at airbag 1 rear portion and corresponding with gas generator 4 positions, second air chamber 102 is positioned at first air chamber, 101 fronts, in first air chamber 101, be provided with trabeculae 2, described trabeculae 2 is the bag shape, and sack is connected with airbag 1 bottom and communicates with gas generator 4 deflation holes, and mediastinum sheet 8 is fixed on the trabeculae 2 with trabeculae 2 adjacents.By trabeculae 2 first air chamber 101 is divided into plenum chamber 101a and last plenum chamber 101b down, on trabeculae 2, is provided with deflation hole 201, will descend plenum chamber 101a and last plenum chamber 101b to be communicated with by trabeculae 2.On mediastinum sheet 8, be provided with deflation hole 801, upper chamber 101b be communicated with second air chamber 102 by deflation hole 801.Mediastinum sheet 8 and the material identical (also can different) of trabeculae 2 with airbag 1.
After gas generator 4 is received ignition order, produce gas, gas is introduced among the lower chamber 101a, by the deflation hole on the trabeculae 2 201, gas enters among the upper chamber 101b that is formed by airbag 1, trabeculae 2 and mediastinum sheet 28, enters in second air chamber 102 that is formed by airbag 1, trabeculae 2 and partition 28 through deflation hole 801 again.Other is with example 1.
Example 3:
As Fig. 5, shown in Figure 6, the present invention has a module carrier 5, on module carrier 5, be provided with gas generator 4, airbag 1, in airbag 1, be vertically arranged with mediastinum sheet 8, by mediastinum sheet 8 airbag 1 is divided into first air chamber 101 and second air chamber 102, first air chamber 101 is positioned at airbag 1 rear portion and corresponding with gas generator 4 positions, second air chamber 102 is positioned at first air chamber, 101 fronts, and on mediastinum sheet 8, be provided with deflation hole 801, first air chamber 101 be communicated with second air chamber 102 by deflation hole 801.Be provided with transverse pulling strip 2 ' at first air chamber, 101 middle parts, transverse pulling strip 2 ' can be along horizontal or oblique layout, transverse pulling strip 2 ' can be one or more, this example is an example with two, transverse pulling strip 2 ' two ends are connected on airbag 1 and the mediastinum sheet 8, by the expansion shape after 101 inflations of transverse pulling strip 2 may command first air chamber.
When the collision of vehicle generation sufficient intensity, gas generator 4 charges into gas in the airbag 1.Gas at first enters by drawstring 2 ' and controls in first air chamber 101 of shape, then enters in second air chamber 102.The whole expansion process of airbag 1 is to launch to windshield 3 or airbag top earlier, then carries out the expansion of airbag 1 bottom, promptly launches downwards.If the occupant is OOP position occupant 7, because airbag 1 upwards launches earlier, insufficient pressure in the airbag 1 so that the occupant be moved, when airbag 2 continues to launch downwards, be that gas is when entering in second air chamber 102, because OOP position occupant 7 has been wrapped in interior location (as shown in Figure 5) by airbag 1 at this moment, airbag 1 can form the pressure to it at the occupant back side, make firm being wrapped in the airbag 1 of occupant, so both prevented that OOP position occupant 7 heads from bumping against instrument carrier panel 6, avoided again because the additional injury that airbag deployment causes OOP position occupant 7.If the occupant is normal position occupant 7 ', after gas passes through two air chambers in the airbag 1, form an airbag shape (as shown in Figure 6) of launching fully, realize protection to the normal position occupant.
