Summary of the invention

The problem that the present invention is based on provides at the other method of the mentioned type of beginning and other equipment, its feasible air bag that can compress the air bag component that is used for self-propelled vehicle in the shortest possible period is produced undersized air bag bag owing to compress operation simultaneously.

About this method; according to the present invention; address this problem by following feature: a kind of air bag that is used to compress air bag component makes described air bag be rendered as the method for air bag bag; described air bag can inflate so that the protection personnel; wherein a) provide Foldable container; this Foldable container has at least one uncovered cap surface; and described air bag can be put into described Foldable container; b) by uncovered cap surface described air bag is put into described Foldable container; c) under the effect of pressure, described air bag is discharged from described Foldable container once more by uncovered cap surface; and d) when when described Foldable container is discharged; described air bag is compressed against on the bearing; so that compress described air bag; to form the air bag bag, wherein, in the folding space that limits by described Foldable container, be provided with pole; described air bag can be placed in the described folding space, and described pole is used for producing impression in described air bag in compressing the process of described air bag.

According to foregoing, in order to compress air bag, Foldable container with at least one uncovered cap surface is provided, under the effect of pressure, by uncovered cap surface air bag is put into container, and by uncovered cap surface air bag is discharged from the container once more subsequently, wherein air bag is being compressed against on the bearing when Foldable container is discharged, thereby air bag is compressed and compresses in this case.

Solution of the present invention has following advantage: can utilize simply constructed folding apparatus to produce undersized air bag bag with air bag in short period, described folding apparatus consists essentially of and is used to admit the Foldable container of air bag and is used for device that air bag is put into Foldable container and air bag is discharged from Foldable container.

Here, air bag puts into that the discharge from Foldable container all advantageously takes place with air bag under the effect of pressure in Foldable container.

Foldable container has for example form of annular cross section, therefore when air bag was put into Foldable container, Foldable container can be bonded on around the air bag circlewise, says exactly, specifically be (but not necessarily), be bonded on around the air bag with osed top boundary wall circlewise.

For this reason, specifically, Foldable container can be configured to a pipe, air bag be put into and discharged along the longitudinal axis of this pipe.

By one and same uncovered cap surface, air bag putting into air bag in Foldable container can be carried out in simple mode from the discharge of Foldable container, but this is not enforceable, that is, yet air bag can be put into and discharged by the cap surface that different (distolateral) of Foldable container is uncovered.

Press thereon bearing at air bag when Foldable container is discharged, advantageously be provided with in such a way with respect to Foldable container, promptly at air bag from the process that Foldable container is discharged, utilize Foldable container sidewall (with respect to air bag be pressed against on the bearing direction transversely) expansion of restriction air bag.In other words, bearing is positioned at the uncovered cap surface near Foldable container like this, make to contact with bearing so that when being compressed against on the bearing when air bag that air bag still is positioned at Foldable container basically fully, wherein air bag is discharged from Foldable container by uncovered cap surface.

Specifically, bearing can be an assembly container, and air bag will be placed in the described assembly container and air bag will be installed in the self-propelled vehicle with this assembly container.In this case, when (in order to compress air bag) was pressed against on the bearing that is formed by assembly container, air bag was put in the assembly container simultaneously, thereby it directly is combined in the air bag component under the situation that does not have other algorithm.In this case, assembly container is the air inclusion producer, and gas generator is used for making airbag aeration, and alternatively, gas generator forms the part of bearing, and air bag is being compressed against on this bearing when Foldable container is discharged.

In improvement of the present invention, be defined in before air bag is placed in the Foldable container, by branch air bag being fixed to bearing (being fixed to assembly container specifically) makes when at first the remaining area of air bag being put into Foldable container for squeeze operation and once more the remaining area of air bag being discharged and when the remaining area of this process air bag was compressed against on the bearing, air bag was always by the connection of this branch's maintenance to bearing from Foldable container subsequently.

In addition, putting into and discharge process of air bag, bearing can be located with respect to Foldable container in such a way, being air bag puts into Foldable container and the free cap surface of the Foldable container of discharging from Foldable container is sealed by bearing by it, say exactly, specifically be, by between Foldable container and bearing (it covers the uncovered cap surface of Foldable container), extending and at first being supported on the Foldable container, secondly being supported on sealing member (form that for example the is sealed tube) sealing on the bearing.

According to improvement of the present invention, piston be installed in movably in the Foldable container and air bag put into and/or discharge process moves, wherein, put into the process of Foldable container at air bag, piston moves away cap surface, wherein by this cap surface air bag is put into Foldable container, and at air bag from the discharge process of Foldable container, the piston towards cap surface moves, and wherein is discharged from by this cap surface air bag.Preferably, air bag puts into that the discharge from Foldable container all takes place with air bag under the effect of pressure in Foldable container.

In this case, this external enwergy regulation, for air bag is discharged from Foldable container, piston action on air bag so that extruding gasbag makes it pass the uncovered cap surface that is used for this purpose and air bag is pressed against the bearing that is arranged at uncovered cap surface back.

For air bag is put into Foldable container, can utilize to act on the air bag and air bag is pressed onto positive pressure in the Foldable container, and/or in Foldable container, produce and air bag is drawn in negative pressure in the Foldable container.In this case, can apply the positive pressure that acts on the air bag, specifically, apply positive pressure to fill air bag in the mode that increases its internal pressure, and in this way, airbag inflation is in Foldable container with gas (air), that is, be placed in the Foldable container.

For air bag is discharged from Foldable container, then, the gas of putting into Foldable container by being pumped in the air bag so that with air bag is emitted from air bag once more, makes air bag become empty once more, specifically, by with described gas sucking-off, makes air bag become empty once more.

In addition, for air bag is discharged from Foldable container, can in Foldable container, produce positive pressure, described positive pressure has the trend that air bag is extruded Foldable container by the uncovered cap surface of Foldable container, described uncovered cap surface provides for this purpose, and described pressure also can act on the moveable piston that is arranged in the Foldable container and along the direction of uncovered cap surface air bag be exerted pressure again then.

Putting into and/or discharge process of air bag, for example utilize bearing and relevant sealing member to seal at least one uncovered cap surface of Foldable container in the mode that can in Foldable container, produce positive pressure and/or negative pressure.

In order just to produce and/or negative pressure, at least one Pressure generator can be provided, for example with the form of pump, for example, by being connected the pump in the corresponding pressure circuit, only not only to have produced positive pressure but also produced negative pressure in simple mode be possible for pump.

Though, a pump not only produces positive pressure but also produce under the situation of negative pressure only using, and has realized the special saving cost and the compact structure of Foldable container, but then, in order to produce negative, positive pressure,, on the one hand vacuum pump and the combination that produces the pump of positive pressure on the other hand may be easily, particularly, if operate folding apparatus with pressure reduction, because if only use a pump, it also is difficult if not complete impossible words that pressure differential is realized.In this case, if it is suitable, on the one hand vacuum pump and the pump that produces positive pressure on the other hand can use public pipeline, so that provide plus or minus pressure in Foldable container or air bag to be folded, described pipeline all is connected to one or another pump by valve in each case.

Pole can be arranged in the folding space that is formed by Foldable container, and air bag puts into described folding space at first and discharge from described folding space with rear gasbag, and when air bag was arranged in Foldable container, described pole can be used for producing impression in air bag.For this reason, described pole can be arranged in the Foldable container movably in the mode of sliding part, is arranged on Foldable container movably along the axis of putting into and discharge air bag specifically.

According to an aspect, when described airbag inflation, described pole acts on the described air bag, and does not enter the inside of the air bag that will fill with gas.More specifically, if comprising the opening of filling described air bag with gas, compacted described air bag make air bag to expand, then described pole acts on the part away from described opening of air bag, and for example, described pole acts on the part that deviates from described opening of air bag.

The effect that can realize with such pole is, in (central authorities) zone of folding air bag bag, only an air bag layer is positioned at the gas generator top that is arranged on the there, the result, in the gas replenishment process of subsequently air bag, can not hit immediately on the folding bag of complexity from the gas generator effluent air, but hit by air-flow outwards on only air bag layer of extruding, as a result, in expansion process, generally speaking be drawn out rather than be pushed out its relevant assembly container more leading to the folding air bag of following described ground floor on the exterior route.This can improve the inflation performance of air bag.

Because pole does not enter the inside of air bag by the opening of air bag, so, need not limit the spatial destribution of pole, thereby can freely select the spatial destribution of pole, so that optimize the folding of air bag with respect to the described opening of air bag.

If the bearing that is arranged on the uncovered cap surface back of Foldable container forms the part of assembly container, then in the process on being pressed against bearing, air bag can be put into assembly container, then it is installed in the self-propelled vehicle with assembly container.

For this reason, closed component container (for example using film) after air bag is pressed into, so air bag stays in the assembly container as the air bag bag, and before it is installed in the self-propelled vehicle with assembly container, can from assembly container, not expand once more.For this reason, the closure elements of closed component container of being used for that for example is form of film for example engages by jointing material by means of bonding or welding and is fixedly connected to assembly container.

Advantageously, after being pressed into air bag in the assembly container, in moving away the process of Foldable container, assembly container directly utilizes closure elements closed component container.

In this case, assembly container advantageously moves along the uncovered cap surface (that is, being arranged essentially parallel to uncovered cap surface) of Foldable container, wherein will be pressed in the assembly container by the air bag that uncovered cap surface has extruded Foldable container.Then, be parallel to the uncovered cap surface of Foldable container and leave in the moving process of Foldable container at assembly container, the closure elements that will for example be form of film in each case is applied to a part of assembly container continuously, in the moving process of assembly container, this part is just in time in that laterally occurring around boundary wall adjacent to Foldable container in moment.

The present invention also provides a kind of air bag that is used to compress air bag component to make described air bag be rendered as the equipment of air bag bag, and described air bag can inflate so that the protection personnel, and described equipment has

-Foldable container, described Foldable container have at least one uncovered cap surface, and described air bag can be placed in the described Foldable container, and described air bag can be discharged from described Foldable container once more,

The specific embodiment

Fig. 1 a and 1b illustrate the folding apparatus of the inflatable bladders of the air bag component that is used for the folder motor-car, use this folding apparatus, can compress air bag in such a way, promptly owing to the air bag bag with air bag can be installed in the power actuated vehicle as undersized air bag component, air bag exists with the form of saving the space.

Described folding apparatus comprises the Foldable container 1 that is the folded tube form, described Foldable container 1 for example is made of plastics or glass, extend first, between the closing cap surface 12 on the uncovered cap surface 11 and second of bottom, top, and between two

cap surfaces

11,12, Foldable container 1 has boundary wall 10, boundary wall 10 with circular pattern around Foldable container 1 and seal the folding space F of Foldable container 1.

Pole 2 and piston 3 are installed among the folding space F of Foldable container 1 movably, the form that sliding part be moved and be to pole 2 can along the longitudinal axis or the length direction R of Foldable container 1, piston 3 can move along described direction R equally---and pole 2 extends through piston 3.Pole 2 has length along the length direction R of Foldable container 1, this length is consistent along the length of described direction R with Foldable container 1 basically, therefore when be arranged on pole 2 in the Foldable container 1 fully, pole 2 one of two

cap surfaces

11,12 by two distolateral 21,22 direct and Foldable container 1 in each case is adjacent.

The length of that see in Fig. 1 a and consistent with the length of Foldable container 1 approx pole 2 only is counted as an example.In principle, the selection of the length of pole 2 makes in the process of folded airbag with formation air bag bag, pole 2 can be realized its function at the formation air bag bag of when beginning explanation in such a way, and the zone that promptly only comprises the air bag bag of an air bag layer is positioned at gas generator or distributes to the top of delivery port of the diffuser of gas generator.For this reason, if suitable, pole 2 also vertically (length direction R) shift out from Foldable container 1.This will guarantee by the sufficient length of pole 2, and this length is considered the pole 2 of being realized by the actuator of distributing to pole 2 moving range of R alongst.

As can be from further finding out Fig. 1 a and the 1b, pole 2 be by the passage 30 of piston 3, and, pole 2 with respect to piston 3 in the axial direction (the length direction R of Foldable container 1) can move.

In addition, folding apparatus has for example Pressure generator of the form of vacuum pump 4, it is operatively coupled to Foldable container 1 and/or air bag to be compressed by corresponding associated line 41,42, therefore Foldable container 1 and/or air bag are the parts of pressure circuit, by this pressure circuit, can in Foldable container 1 and/or air bag, just produce and/or negative pressure.Power to Pressure generator 4 by the power lead 40 that provides for this purpose.

The size that depends on the positive and negative pressure that produces by Pressure generator 4, promptly, specifically, as the pressure differential function between the negative pressure of positive pressure that produces and generation, in each case, on the one hand can be provided for producing the independent vacuum pump of negative pressure, can provide different on the other hand and be used to produce the positive pressure supply source (pneumatic attaching parts) of positive pressure with it.In this case, a plurality of as just and/or the pump of negative pressure supply source to use the public associated line lead to Foldable container 1 and/or air bag be fully possible, this associated line all is connected to one or other pumps by valve in each case.Therefore, as an example Pressure generator 4 is regarded as below and all comprised one or more pumps in each case.

Foldable container 1 first, the back of the uncovered cap surface 11 of bottom, assembly container 100 with the gas generator 200 that is installed in wherein is arranged in the support 7, this assembly container is used for admitting the air bag of the compacted formation air bag bag that is used for self-propelled vehicle, this air bag will be installed in the self-propelled vehicle as air bag component with gas generator 200, and air bag is contained in the air bag component.

In addition, the

device

5,6 that after folding air bag bag is pressed in the assembly container 100, is used for closed component container 100 be arranged to Foldable container 1 around horizontal boundary wall 10 adjacency.The structure and the function of described device will further illustrate in greater detail with reference to figure 8 and 9 below.

In order to utilize the folding apparatus shown in Fig. 1 a and the 1b to compress air bag G, be fixed to assembly container 100 and its other zone uncovered cap surface 11 by Foldable container 1 according to as shown in Figure 2 air bag G by retaining part H and be introduced among the folding space F of Foldable container 1.At this moment, pole 2 moves in such position on the Foldable container 1, makes it not act on the air bag G at first.

In addition, air bag G is provided with opening O, and gas can charge among the air bag G by this opening O.For example, the part of gas generator 200 or diffuser can be given prominence to the inside of passing opening O and entering air bag G.

Air bag G be introduced among the folding space F of Foldable container 1 one be enough to make that it no longer can skid off the degree of Foldable container 1 easily after, support 7 moves with assembly container 100 and gas generator 200 and closely leans against on the uncovered cap surface 11 of Foldable container 1, make support 7 and assembly container 100 together by sealing member 8 sealings of for example tubular seal, sealing member 8 is the boundary wall 10 of Foldable container 1 on the one hand and is to extend between support 7 and the assembly container 100 on the other hand.Thereby, then, the folding space F of Foldable container 1 at its uncovered cap surface 11 places also so that the air tight mode is sealed basically.

Foldable container 1 another, osed top cap surface 12 places, sealed open in such a way promptly can not take place and extraneous equalization of pressure there basically, wherein pole 2 can move through this opening with the form of sliding part.

According to Fig. 3 and 4, in the zone of folding space F above air bag G, produce negative pressure by relevant pressure pipeline 42 by means of the Pressure generator of the form that is at least one pump 4 now, negative pressure has further draws in trend in the Foldable container 1 with air bag G.Simultaneously, to the blanketing gas of air bag G own, therefore, produce (just) pressure by means of Pressure generator 4 and the pressure pipeline 41 that provides for this purpose in air bag G, described pressure has strengthened the expansion of air bag G in the folding space F of Foldable container 1.

By this method, the piston 3 that is positioned at air bag G top also moves along direction R1, and direction R1 is parallel to the length direction R of the Foldable container 1 on the direction of osed top cap surface 12 at an upper portion thereof.

Then, according to Figure 4 and 5, make the pole that vertically moves 2 that is the sliding part form be introduced in the uncovered cap surface 11 that direction among the folding space F of Foldable container 1 further moves to Foldable container 1 on the contrary along direction R2 and air bag G, pole 2 is (on the part away from its opening O that acts on air bag G, perhaps speak by the book more, on a part that acts on described opening O of deviating from of air bag G) formation impression in air bag G.

Move by the above-mentioned of pole 2, target is that (central authorities) zone that will fold the air bag G that forms the air bag bag in such a way is pressed against on the gas generator 200 that is arranged in the assembly container 100, make an individual layer having only air bag G be positioned at the top, outflow aperture of gas generator 200, therefore---as illustrating beginning---at the inflation performance that from the process of gas generator 200 blanketing gas, can realize the improvement of air bag G.

Fig. 5 illustrates the setting that is in a kind of state, and wherein airbag inflation makes it occupy half of folding space F basically to such degree in the Foldable container 1, and wherein air bag G has the impression that is produced by pole 2.

After as shown in Figure 5 air bag G has put into Foldable container 1 fully, put upside down the pressure direction (pumping direction) in the pressure circuit of Pressure generator (at least one pump 4), therefore, on the one hand, now at the region generating positive pressure of the folding space F that is positioned at the Foldable container 1 above air bag G and the piston 3, on the other hand, the gas that advances into air bag G is earlier extracted out from air bag G once more.Under the effect of the positive pressure that in the upper area of Foldable container 1, produces, 1 uncovered cap surface 11 moves and by described cap surface 11 air bag G is pressed in the assembly container 100 piston 3 along direction R2 towards Foldable container, described assembly container 100 is arranged on described cap surface back, and form bearing with support 7 and gas generator 200 there, air bag G is compressed against on the bearing under the effect of piston 3.

According to Fig. 7, this finally causes (now become empty) air bag G to be pressed in such a way in the assembly container 100, and promptly it is present in the there as air bag bag compactness, undersized.The generation of pressure finishes immediately, and is support 7 and assembly container 100 on the one hand, is that the seal adaptor between the Foldable container 1 is removed on the other hand.

Subsequently, make support 7 be parallel to its uncovered cap surface 11 and move away Foldable container 1 with the assembly container 100 and the gas generator in being arranged on assembly container 200 and the compacted air bag G that are contained in wherein, say exactly, on the direction of the

device

5,6 that is used for closed component container 100, move away Foldable container 1 along direction D1.

This

device

5,6 comprises that the closure member V that is used for being form of film puts on assembly container 100 so that the device 5 of closed component container 100.The closure member V of film like is wound on the drum 50 and rotation that can be by drum 50 is unclamped so that closed component container 100 thus from drum 50.For this reason, by a plurality of rollers 51 guide in such a way film like closure member V be film like closure member V a part basically along with Foldable container 1 first, plane and Foldable container 1 adjacent straight ground connection that uncovered cap surface 11 is identical extends.

The result, when assembly container 100 when support 7 is parallel to cap surface 11 and moves away Foldable container 1, directly therefore directing assembly container 100 below film like closure member V prevents air bag G " ejection ", and described " ejection " can cause air bag G to reveal from assembly container 100.Film like closure member V takes place along the moving simultaneously of uncovered cap surface 11 of Foldable container 1 together with assembly container 100 from the expansion of drum 50 and holding device 7, makes those zones of the assembly container 100 that exposes with Foldable container 1 adjacent transverse ground in the moving process of holding device 7 cover continuously with film like closure member V.

In order film like closure member V to be fixed (engaging) in assembly container 1 by jointing material, use laser 6, it is welded to package shell 100 by laser emission L with film like closure member V.

Fig. 9 illustrates assembly container 100, utilize film like closure member V sealing with described assembly container 100 with the air bag G that is arranged on gas generator 200 wherein and pack into wherein as air bag, this assembly container can be installed in the self-propelled vehicle with the form of the air bag component of complete preproduction now.

In a word, the said method characteristics are, by in Foldable container, producing negative pressure by means of pressure circuit and in air bag, producing positive pressure simultaneously, the air bag of preassembled air bag component is drawn in the Foldable container that is the folded tube form, and wherein Foldable container and air bag are combined in the pressure circuit.Specifically, therefore pump produces negative pressure with air there from the Foldable container sucking-off, and described air is pressed into air bag so produces positive pressure there, and positive pressure helps air bag to move in the Foldable container 1.

After air bag is put into Foldable container, if suitable, pole is being driven in the air bag so that after producing impression therein, put upside down the pumping direction of pressure circuit and make air bag become empty, allow the air admission Foldable container so that produce positive pressure simultaneously.This positive pressure is on piston, piston will become empty air bag by uncovered cap surface and extrude from Foldable container once more, say exactly, it is pressed against on the bearing that is formed by the assembly container (having the gas generator that is installed in wherein) that is arranged in the holding device.In this way, air bag is compressed and forms the air bag bag, says exactly, makes that being compressed the air bag that forms the air bag bag is contained in the assembly container immediately.

Pumping operation finishes subsequently, and holding device moves away Foldable container with the uncovered cap surface that assembly container is parallel to Foldable container, and wherein assembly container reveals from assembly container so that prevent air bag with the sealing of film like closure member.In this process, also for example the film like closure member is fixed in assembly container by bonding or welding (by static laser, particularly at laser beam not under the situation of deflection).

Used folding apparatus characteristics are that structure is compact and in light weight, and allow to finish all operations step that is used to compress air bag in a device (equipment), and described control step comprises being pressed in assembly container (package shell).If suitable, can operate a plurality of such folding apparatus in process of production concurrently.
