Abstract
A low risk deployment passenger airbag system has two separate airbags, a top-mounted airbag 11 and a mid-mounted airbag 12. The top-mounted airbag 11 deploys into the adult occupant's head and upper torso areas without generating substantial downward deployment, while the mid-mounted airbag 12 deploys into the adult occupant's lower torso area without generating substantial upward deployment. This mode of substantially horizontal deployments can provide an out-of-position child with a safe mode of airbag inflation, reducing the risk of neck injuries. An infant in a rear facing child seat receives distributed small forces from two airbags with a possible time delay in initial airbag contact rather than a concentrated large force from the conventional single passenger airbag. The total capacity of the two airbags is about the same as the conventional single passenger airbag and thus can provide as effective protection. The top-mounted airbag 11 has a larger capacity in volume than the mid-mounted airbag 12 and serves as a main airbag for protecting in-position occupants. The mid-mounted airbag may be deployed at low output or no output level for belted occupants during high-speed crashes, which in turn can help reduce the injury values of an infant dummy in a rear facing child seat during the low risk deployment test.

The specific embodiment
With reference to Fig. 1, wherein traditional single passenger airbag module is shown as the top and is installed in the instrument carrier panel.Air bag cushion 3 launches towards the head and the torso portion of adult-passenger 2.In the airbag deployment process, shown in dotted line, air bag can produce the component of sizable downward expansion, and is as shown in arrow 6.The head that the component 6 that launches downwards can will not be in the children 1 of correct position pushes away downwards, and potentially neck is caused serious injury.The cover 5 that air bag module has generation of gas charging blower 4 and keeps charging blower 4 and air bag cushion 3.
Fig. 2 shows the middle part and is installed in the interior another kind of traditional single passenger airbag module of instrument carrier panel.This air bag module comprises towards the air bag cushion 7 of the head of adult-passenger 2 and torso portion expansion.In the airbag deployment process, shown in dotted line, air bag 7 can produce sizable component that upwards launches, and is as shown in arrow 10, and can be trapped within the children's 1 that are not in correct position lower jaw below.The component 10 that upwards launches can upwards push away lower jaw, and potentially neck is caused serious injury.Air bag module also comprises generation of gas charging blower 8 and the cover 9 that keeps charging blower 8 and air bag cushion 7.
Fig. 3 shows preferred embodiment passenger side, gas-bag system of the present invention that is used in vehicle.This gas-bag system comprises top-mounted airbag 11, and it is installed in the top surface rear of instrument carrier panel basic horizontal.Top-mounted airbag 11 is launched towards the head and the upper torso region of adult-passenger 2.Top-mounted airbag 11 is at first launched obliquely up along Windshield.When top-mounted airbag 11 further expands, its head and neck area towards the children 1 that are not in correct position essentially horizontally advances, as shown in arrow 17, thereby the single traditional top-mounted airbag 3 shown in can image pattern 1 produces downward substantially component like that, has reduced the danger of cervical injuries thus.
This gas-bag system also comprises middle part mounted airbag 12, and it is installed in instrument carrier panel surperficial rear vertical basically, that face the passenger.Middle part mounted airbag 12 is launched towards the lower torso area of adult-passenger 2.Middle part mounted airbag 12 common on even keels (as shown in arrow 18) and down (shown in arrow 18a) expansion, thereby the single tradition middle part mounted airbag 7 shown in can image pattern 2 produces the component that makes progress substantially like that, has reduced the danger of cervical injuries thus.The horizontal development pattern of top-mounted airbag 11 and middle part mounted airbag 12 can provide the airbag deployment of safety mode for the children that are not in correct position.
The size of the air bag 11,12 of gas-bag system of the present invention is basically less than traditional single passenger airbag 3 or 7 size.This helps at the impulsive force that disperses during the airbag inflation to be applied on the children that are not in correct position.Because it is farther that top-mounted airbag 11 distances are not in the passenger of correct position, therefore top-mounted airbag 11 is compared with middle part mounted airbag 12 and is had less aggressiveness, thus, top-mounted airbag pad 11 preferably when all launching on volume basically greater than middle part mounted airbag pad 12.The expansion volume of top-mounted airbag pad 11 can be between 60 to 120 liters, and the expansion volume of middle part mounted airbag pad 12 can be between 30 to 70 liters.In certain embodiments, the volume of top-mounted airbag is bigger by 25% than the volume of middle part mounted airbag at least.In other embodiments, the volume of top-mounted airbag is bigger by 50% than the volume of middle part mounted airbag at least.In other embodiments, the volume of top-mounted airbag is at least than the volume big 75% or 100% of middle part mounted airbag.
In use, top-mounted airbag 11 and middle part mounted airbag 12 are respectively by gas separated generation charging blower 13 and 15 and inflation.Charging blower 13 and 15 can be suitable type well known in the art.Air bag 11 and 12 expands because the existence of some predetermined factors, charging blower 13 and 15 are triggered independently of one another.
The top-mounted airbag 11 among Fig. 3 and the expansion of middle part mounted airbag 12 have been shown among Fig. 4, the baby 19 of the child seat 20 (it is installed on the seat by convention) that is positioned at backwards wherein also has been shown.Top-mounted airbag pad 11 launches towards the head zone of child seat 20, and middle part mounted airbag pad 12 is towards the chest region expansion of child seat 20.
As shown in Figure 4, air bag 11,12 can expand in continuous slightly mode to contact with child seat 20.In order to guarantee the relative timing between air bag 11,12 and the child seat 20, may need to make that the triggering of charging blower 13,15 is offset mutually.The triggering that whether needs to be offset charging blower 13,15 mainly depends on following factor: the size of the size of charging blower and type, each air bag and the relative front and back position and the air bag doors of material, air bag and/or push the design and the material of seam open.
Owing to possible time delay impact is distributed to a plurality of parts of child seat 20, so the injury of the expansion in the child seat 20 peak value can be lower than the injury peak value of the single gas-bag system of tradition commonly known in the art.
Fig. 5 shows a preferred embodiment of the present invention, and wherein each air bag module has independent charging blower 13,15.Appropriate section in the traditional single air bag that part in the top-mounted airbag module (for example charging blower 13, cover 14 and fill up 11) is installed less than top shown in Figure 1.Similarly, the appropriate section in the traditional single air bag installed less than top shown in Figure 2 of the part in the middle part mounted airbag module (for example charging blower 15, cover 16 and fill up 12).Described air bag module can have diffuser 21,22, with the output of control charging blower 13,15 to each air bag cushion 11,12.Preferably, the output level of the activation time of two air bags 11,12 and charging blower 13,15 is controlled separately.
Fig. 6 shows the diagram of circuit of the optional airbag deployment algorithm that is used for preferred embodiment shown in Figure 5.In speed per hour is in the high-speed crash of the anterior rigid barrier test in level land of 40 miles per hours, for passenger with belt, the gas that install at the middle part is wrapped up in and can be launched with lower output, does not perhaps launch, because safety strap can enough retrain passenger's trunk and pelvis effectively.The expansion output of the reduction of above-mentioned middle part mounted airbag 12 can help to reduce to be positioned at the injury values of the Infant model of child seat backwards in low dangerous expansion test.
Fig. 7 shows another embodiment of the invention, and one of them charging blower 23 produces gas, thinks top-mounted airbag 11 and 12 inflations of middle part mounted airbag.Charging blower 23 is arranged in the single pipe (conduit) 24, and pipeline 24 is communicated with air bag 11,12 fluids.More specifically, pipeline 24 comprises top that engages with top-mounted airbag 11 and the bottom that engages with middle part mounted airbag 12.Preferably, charging blower 23 is arranged between the top 25 and bottom 26 of pipeline 24.Should be realized that charging blower 23 also can be arranged on any end of pipeline 24, keep simultaneously being communicated with air bag 11,12 fluids.In addition, can between charging blower 23 and air bag 11,12, along any suitable position of pipeline 24, use the passage of diffuser 21,22 or different opening size, offer the amount and the speed of the gas of each air bag 11,12 with control.
Fig. 8 shows another embodiment of the invention.Passenger airbag system 30 comprise generation of gas charging blower 32, the gas flow that taken place of control diffuser 34, air bag cushion 36, hold the cover 38 of air bag cushion.In the present invention, cover 38 extends to the middle part or the top 44 of instrument carrier panel from the top 42 of instrument carrier panel 40 as individual unit.Air bag cushion 36 can be covered by the top layer 46 of instrument carrier panel.When measuring on the longitudinal direction of vehicle, the length of cover 38 of the present invention is substantially greater than traditional air cell covering.It is enough greatly to cover the top and the middle part major part of instrument carrier panel.The length of cover 38 can be the twice at least of conventional balloon cover, to cover traditional top the position of air bag and the position that air bag is installed at the tradition middle part is installed.In this article, the level but not vertically and basically in the face of the part of Windshield more basically of its surface in the instrument carrier panel is represented at the top of instrument carrier panel.The middle part of instrument carrier panel or front portion are the more vertical basically but not levels in its surface and basically in the face of passenger's part in the instrument carrier panel.
Though it is basic identical that the width of the air cell covering 38 of the present embodiment of the present invention is preferably with traditional air cell covering, comparing it with traditional size can be wideer, so that air bag cushion further is distributed on the instrument carrier panel.Under the situation of given width, when length increases, with the direction of instrument carrier panel Surface Vertical on the degree of depth measured should reduce so that the volume of cover remains unchanged.When fully launching, air cell covering preferably has shape and the volume identical with traditional top-mounted airbag cover.
Though the center is preferred (as shown in Figure 8), charging blower 32 can be arranged in the interior any position of air bag module.Because the length of cover is longer, therefore the gas that is produced by charging blower can produce higher air pressure near charging blower, and produces lower air pressure in the position away from charging blower, and the air bag cushion that causes thus not expecting launches.In order to address this problem, the diffuser 34 that is used for the present embodiment of the present invention can have the open area of different size, with the expansion mode of control air bag cushion.As an example, the amount of open area can be along changing as Fig. 9 and longitudinal direction shown in Figure 10, thereby all even radioactivation that reduces air bag cushion is in a controlled manner launched.The open area is manufactured on away from the direction of charging blower to be increased gradually.Can change open area (as shown in Figure 9) by changing hole size, perhaps, if hole size remains unchanged, can change the open area by the density (quantity of per unit region apertures) that changes the hole, as shown in figure 10, perhaps adopt the combination of above two kinds of methods.
In order accurately to adjust the expansion of air bag cushion, can further change opening hole size and pattern.For example, may wish that the top of air bag cushion is launched sooner than the bottom, keep radioactivation to launch simultaneously, because before the net shape after reaching airbag deployment, the distance that top area need be advanced is longer.Air bag aggressiveness when this effect also can make airbag deployment between top and the bottom distributes more equably.Because the top of air bag cushion is more farther than the passenger that bottom (middle part of instrument carrier panel or front portion) distance is not in correct position, so it is safer usually.In order to realize different development rates, except as Fig. 9 and shown in Figure 10, on direction the varying sized and/or density away from charging blower, the open area can also further become big towards the top of air bag cushion.
For the passenger who is not in correct position, uniform and radial expansion of air bag cushion as shown in figure 11 can provide following two major advantages.At first, it provides the power of the dispersion that spreads all over passenger's body, rather than common concentrated force in the conventional balloon shown in Fig. 1 and Fig. 2.The power of this dispersion can reduce the danger that the children that are not in correct position in the child belt and baby are damaged.Secondly, this expansion pattern is to look basically from sidepiece to launch along the profile radiation of instrument carrier panel.This radial expansion can significantly reduce the danger that neck is damaged.On the contrary, conventional balloon be deployed in neck area near have sizable component downward or upward, shown in the arrow among Fig. 1 and Fig. 2.
It will be understood by those skilled in the art that under the situation that does not deviate from scope of the present invention or instruction, the embodiment of the present invention of Miao Shuing can change in a different manner herein.For instance, gas-bag system can be by forming more than described two air bag modules herein.As an example, the system with three air bag modules can be provided, each module is along public basically path order setting, with passenger's direct contact, and can not produce the bigger expansion component of not expecting up or down.In addition, though being shown as, air bag module is provided with top or top-mounted airbag and bottom or middle part mounted airbag, but also can be along the two or more independent air bags of being arranged side by side in a lateral direction of instrument carrier panel, perhaps with other angle setting.To those skilled in the art, other modification is conspicuous.Therefore, content disclosed in this invention should be with scope explanation widely.
