Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the noun of locality of use typically refers to the upper and lower, left and right in accompanying drawing as " upper and lower, left and right ", and " forward and backward " to be defined as in vehicle towards the direction of headstock is front, after the direction of facing tailstock is.
See Fig. 1, Fig. 2 and Fig. 3, the present invention relates to a kind of airbag apparatus, this airbag apparatus is arranged in order to protect human body from collision injury in vehicle, but is not limited to be applied to vehicle.Usually, airbag apparatus can comprise airbag 1, gas generator (such as airbag 1 is communicated with the air flow guiding device of gas generator, so that be sent in airbag 1 by the gas of generation), sensing element 2 and controller 3 etc. for inflating to this airbag 1.Wherein, airbag 1 and gas generator can be arranged on multiple position, and in the present invention, airbag 1 and gas generator are arranged in the headrest 4 of seat.As depicted in figs. 1 and 2, headrest 4 is installed on the seat by support 5.In headrest 4 manufacturing process, first airbag 1 and gas generator are fixed in headrest 4, and lignilite (not shown) is set on headrest 4, so that launch when airbag 1 is inflated.In other words, airbag apparatus can comprise inflated condition and non-inflated state.
At storing cycle with when normally travelling, airbag apparatus is in non-inflated state, and airbag 1 shrinks and folds under this non-inflated state.Say further, when airbag 1 and gas generator are arranged on headrest 4, airbag 1 shrinks and is folded in headrest 4 under non-inflated state.When a vehicle is in a collision, after the collision alarm that sensing element 2 detects is delivered to aforesaid gas generator, gas generator is started by controller 3, start to produce gas and gas be filled in airbag 1, make airbag apparatus be in inflated condition, airbag 1 can launch because gas is filled under this inflated condition.When airbag 1 and gas generator are arranged on headrest 4, lignilite on headrest 4 can rupture under the aeration of airbag 1, airbag 1 is made to stretch out from headrest 4 and to launch, thus forming the ring part 11 of the non-closed for surrounding human body head and/or neck, this ring part 11 is conducive to airbag 1 to launch respectively from the both sides of human body because of non-occluded configuration and surrounds head and neck.
Structure after being launched as can be seen from above-mentioned airbag 1, after collision happens, the ring part 11 of non-closed that airbag 1 launches can limit head and neck well to all directions activity, prevent the collision of head all directions, such as, head can be reduced because of inertia to preshoot, thus prevent head from colliding in front, neck sprains.And, after head moves among a small circle in ring part 11, due to aerification in airbag 1, there is extraordinary buffering effect, even if thus head and collision happens, also can slow down the collision of head and vehicle because of buffer action, improve safety during vehicle collision.
In said structure, described airbag 1 is elastic bag, such as, make by materials such as nylon.Described gas generator can be all kinds known in the art, such as, be boosting-type gas generator and comprise body, priming, gunpowder, the quick-fried device of point and Wiring harness connector, air flow guiding device etc. occur.Be known in those skilled in the art about the concrete structure of boosting-type gas generator and action principle, be not described in detail at this.See Fig. 3, the described sensing element 2 for collision detection signal can be polytype sensor known in the art, and it is mainly for detection of crash acceleration signal.Described controller 3 is electrically connected on gas generator and sensing element 2 simultaneously, controls gas generator with the detection signal according to sensing element 2.Wherein, when gas generator of the present invention is arranged on headrest 4, the wire harness of gas generator passes the support 5(of hollow see Fig. 1 and Fig. 2, for supporting the support of headrest 4) be electrically connected with controller 3 afterwards.Under very slight collision, acceleration signal value is minimum, and controller 3 receives minimum acceleration signal value, can not start gas generator; When above-mentioned acceleration signal value meets or exceeds predetermined initiation value, controller 3 will control gas generator work, and airbag 1 is inflated, to carry out safety guard-safeguard.
In a preferred embodiment, airbag 1 can also form supporting pad portion 12 in the deflated condition, and this supporting pad portion 12 is connected to ring part 11 and extends towards neck in ring part 11.As shown in Figure 1, supporting pad portion 12 is formed in the non-closing position near ring part 11, extends towards neck with approximate horizontal direction.In this embodiment, supporting pad portion 12 is two and is fan-shaped, but being appreciated that supporting pad portion 12 can be set to according to actual needs multiple, and can being other shapes, such as, also can be the ring gasket portion etc. adapted with neck and lower jaw.Be appreciated that the formation in supporting pad portion 12 can slow down the downforce of head and reduce the speed of advancement of head, head and neck can be protected better to make airbag apparatus.
For describing the structure of the ring part 11 after airbag 1 expansion better; airbag 1 of the present invention can be formed as making ring part 11 to comprise the first protection portion 11a in the deflated condition and from downward-sloping the second protection portion 11b of this first protection portion 11a, make the height of the first protection portion 11a be greater than the height of the second protection portion 11b.As depicted in figs. 1 and 2, the first protection portion 11a mainly refers to the part that can contact with the rear side of human body head and neck, in order to buffer shock-absorbing.Second protection portion 11b refers to the part that can contact with the both sides of human body head and neck and front side, with to head and neck formation actv. envelope.For avoiding blocking the visual field, the especially visual field of chaufeur, needs the part that contacts with the front side of neck suitably to reduce highly, thus ring part 11 be formed as from the first protection portion 11a downward-sloping seamlessly transit to the second protection portion 11b.
Based on above-described airbag apparatus, the present invention can relate to a kind of vehicle, wherein, installs above-mentioned airbag 1 and gas generator in the headrest 4 of vehicle.And the sensing element 2 of airbag apparatus can be arranged on the position of very easily being collided, such as, be arranged on the front portion of vehicle, two sides and rear portions etc.When a vehicle is in a collision, airbag 1 stretches out from the lignilite of headrest 4, to protect head and the neck of human body.After collision case, the gas in airbag 1 can be laid down, and airbag 1 is folded in headrest 4, and sewing-end rests the head on 4 again.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible array mode.
In addition, also can carry out combination in any between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
