Airbag for a vehicle 100 below with reference to Fig. 1-Fig. 2 descriptions according to the utility model embodiment.As Fig. 1- Shown in Fig. 2, included according to the airbag for a vehicle 100 of the utility model embodiment：Airbag body 1, gas generator 2nd, multiple gas passages 3 and controller.

The inside of airbag body 1 has air bag cavity, and further, air bag cavity is separated into multiple air bag cavitys 11, gas Body generator 2 is arranged on airbag body 1 and for being inflated to multiple air bag cavitys 11, each gas in multiple gas passages 3 Corresponding air bag cavity 11 is connected by body passage 3 with gas generator 2, and at least two gases lead in multiple gas passages 3 The size in road 3 differs, it is preferable that could be arranged to from the diameter for each gas passage 3 that air bag cavity 11 is connected different Parameter, thus when gas generator 2 works, the gas flow difference in each air bag cavity 11 is so that each air bag cavity 11 Rigidity it is different, can so meet that automotive interior occupant to the rigidity requirement of the different parts of air bag 100, enters in collision process And preferably protect the personal safety of occupant.

Further, controller is connected with gas generator 2, and specifically, when a collision occurs, controller can be sent out to gas Raw device 2 sends firing command, and gas generator 2 produces gases at high pressure immediately, and gases at high pressure are entered respectively by multiple gas passages 3 Enter each air bag cavity 11, so that air bag 100 is opened rapidly.

According to optional embodiment of the present utility model, airbag body 1 can be sewed by textile material and formed, further Ground, textile material can be the materials of PA (nylon) 66, so that air bag 100 has high-tensile, resistance to good toughness etc. excellent Point.

Certainly, airbag body 1 can be not limited to above-mentioned PA66 materials, can also use the good material of other obdurabilities.

According to optional embodiment of the present utility model, air bag 100 can also include：Separation structure 12, separate knot Structure 12 will be divided into multiple air bag cavitys 11 inside airbag body 1, now air bag 100 is configured to multi-cavity air bag, so as to full The collision demand of sufficient occupant's different parts.

Further, separation structure 12 can be fabric side piece, and alternatively, the surface of fabric dough sheet can be done at coating It reason, so on the one hand can increase air-tightness, on the other hand can avoid high temperature and high pressure gas caused by gas generator 2 to separating The influence of structure 12.

According to one embodiment of the present utility model, as depicted in figs. 1 and 2, air bag 100 can also include：Transition Cavity 13, transitional cavity 13 are connected with gas generator 2, and transitional cavity 13 passes through multiple gas passages 3 and multiple airbag chambers Body 11 is connected, and further, the upper end of gas passage 3 is spaced apart with the inner roof wall of airbag body 1.

So, after gas generator 2 is ignited, gas caused by gas generator 2 initially enters transitional cavity 13, so Enter afterwards by multiple gas passages 3 in multiple air bag cavitys 11, so as to inflate for air bag cavity 11, be vehicle interior structure with Cushion space is provided between occupant.

According to optional embodiment of the present utility model, as depicted in figs. 1 and 2, can be set on each air bag cavity 11 There is bleeder port 111, so when occupant impacts air bag 100, air bag cavity 11 can be lost heart by bleeder port 111, be entered One step, the size of at least two bleeder ports 111 is unequal in multiple bleeder ports 111, i.e., losing heart on each air bag cavity 11 Hole 111 may be sized to different parameters, and such occupant each air bag cavity 11 after air bag 100 is impacted is losing heart During throughput it is different, so as to make it have different rigidity, to meet occupant to the firm of the different parts of air bag 100 Degree demand.

In summary, according to the airbag for a vehicle 100 of the utility model embodiment, by by airbag body 1 It is divided into multiple air bag cavitys 11, may be such that the rigidity after air bag detonation in each air bag cavity 11 is different, so as to realize to occupant Different parts play different degrees of protective effect, air bag 100 is more effectively protected occupant.

The utility model additionally provides a kind of vehicle, and the vehicle includes above-mentioned airbag for a vehicle 100, so as to It is safe, good to the protecting effect of occupant to have the advantages that.
