    The invention relates to a method for packaging an airbag for the protection of a person. In addition to this, the invention relates to an airbag packaged for the protection of a person. In addition, the invention relates to a package for an airbag for the protection of a person, an airbag module and a vehicle security system.
    It is known from the prior art that the folded driver air bags are mounted in the steering wheel of a vehicle. In a mounting variant, the folded airbag must remain spaced from a module blank in the mounted state to allow the module blank to be compressed downward. The downward compression of the module cache is necessary, for example to trigger a horn. It is known in this context, as shown in Figure 1, for example, surround the folded airbag 11 with a strap 10, for example made with the material of the airbag and fix it to a support of module 12. The attachment to the module support 12 is carried out, for example, by pulling or by putting the strap 10 with two holes on the bolts 13 of the module support 12. The strap 10 is configured, with respect to its length , so that the holes can be placed on the ends 15 of the bolts 13. At both ends of the strap 10, an additional packing surface 16 is required so that the strap 10 can be driven onto the bolts 13.
    Once the holes are threaded into the bolts 13, the tension acting on the strap 10 decreases so that the volume of the folded airbag 11 is increased. In the permanently mounted state, the airbag therefore has an unnecessarily large volume. In addition, the method shown for packaging an airbag is relatively complex with respect to its implementation. The object of the present invention is to provide a method for packaging an airbag for the protection of a person by which the airbag has a small volume even when mounted.

    The method for packaging an airbag for the protection of a person according to the invention relates in particular to an airbag of driver arranged to be integrated in a steering wheel. The method for packaging an airbag for the protection of a person according to the invention comprises the steps of: - folding an airbag, - attaching the folded airbag to a module holder, - positioning the folded airbag fixed to the module holder relative to a package comprising a plurality of surface portions so that the respective outer ends of the surface portions protrude from the airbag, - folding each of the outer ends of the surface portions towards the center of the package so that the folded airbag is packed at least in parts, and - connect, in particular weld, in parts, the outer ends of the surface parts to the airbag.
    Therefore, the invention is based on the idea of connecting, in particular soldering, a package to the airbag so that the length of the package or individual surface portions of the package can be independently selected. the length of the bolt of a module support.
    In the simplest of cases, the package is an elongated strap comprising two surface parts, that is to say from the center of the strap, the left and right surface portions having left and right ends, the two ends or both outer ends of the surface portions being connected, in particular welded, to the airbag. Alternatively, it is possible to glue and / or sew the outer ends of the surface portions to the airbag.
    In an independent aspect, the method for packaging an airbag for the protection of a person according to the invention is based on the steps of: - folding an airbag, - attaching the folded airbag to a module holder which preferably comprises at least two bolts, - positioning the folded airbag fixed to the module holder with respect to a package having a plurality of surface portions so that the respective outer ends of the surface portions protrude the airbag, - bend each of the outer ends of the surface parts towards the center of the package so that the folded airbag is packed at least in parts and at least two surface parts are arranged to be overlapped at least in parts in an overlapping zone, and - to connect, in particular to weld, in parts at least two x surface areas between them in the overlapping area.
    In an independent aspect, the invention is based on the idea of positioning a package with respect to a folded airbag attached to a module holder so that at least two surface portions or at least the respective outer ends surface parts protrude from the airbag. Then, each of the outer ends of the surface portions is folded in the direction of the center of the airbag of the package so that the folded airbag is wrapped at least in parts. The lengths of the surface portions are selected so that at least two surface portions, in particular two respective outer ends of the surface portions, can be arranged to overlap at least in portions in an overlap area. This is followed by the connection, in particular welding, of at least two parts of the surface to each other in parts in the overlapping zone. As an alternative to welding, at least two surface portions may be connected together in the overlap area by stitching and / or gluing.
    During the welding of at least two surface portions together in the overlap area, it is possible to weld at least two surface portions with the airbag in the overlap area. Therefore, it can be imagined that during a welding operation, the two surface portions are welded, not only to each other in the overlap area, but also in addition to the airbag. In addition, the package may be welded in the overlap area or outside the overlap area in addition to the air bag. The connection, which is referred to as the connection term, particularly partial welding, provides that the surface portions do not need to be connected or welded throughout the overlapping area. The connection or welding shall be carried out only to the extent that, in the unactivated state, a packaged airbag is affixed tightly to the module carrier due to the connected packaging .
    At least one surface portion of the package may have at least one preferably curved and / or circular segment extension at the outer end. An extension configured in this manner may be part of the overlap area formed by at least two surface portions, for example.
    In another embodiment of the invention, at least one surface portion comprises two preferably curved and / or circular segment-like extensions at the outer end. An outer end of a surface portion may include, for example, an outer surface edge that has a straight or curved shape. In the corner regions of the surface edge that are formed by the longitudinal extensions of a surface portion, the extensions may be formed, for example. The extensions can be formed in the form of tabs as circle segments and / or with curved shapes. There is no exhaustive list of possible geometric shapes of extensions. Preferably, the extensions should be designed so that overlapping areas as large as possible can be formed with surface portions that must be arranged to overlap.
    At least one extension of a surface portion may protrude from the width of the dedicated surface portion to the non-connected state, in particular not welded. The width of a surface portion is formed, for example, by the outermost edge of a surface portion, which is formed to be spaced at most from one center of the surface portion. At least one extension projects from this width or respectively at least one extension is formed at the surface portion so that the width of the surface portion is increased in the area of the extension. It is also possible to design a surface portion with a dedicated extension or dedicated extensions, respectively, which both protrude from the width of the dedicated surface portion. It is also conceivable that a surface portion comprising two extensions is configured symmetrically with respect to an axis of symmetry extending transversely to the width of the surface portion. This facilitates the manufacture and reduces the manufacturing costs of a part of surface.
    A respective overlapping area of the two surface portions arranged to overlap, is preferably formed by two extensions of two surface portions, in particular two parts of adjacent juxtaposed or folded surfaces of the package.
    In another embodiment of the invention, at least one surface portion of the package comprises a recess, in particular a cutout, at the outer end, wherein the folded airbag attached to a carrier of module is positioned relative to the enclosure so that at least one bolt of the module support is positioned in a recess. In other words, a recess at the outer end of a surface portion can serve as a positioning aid when positioning the package relative to the airbag and when folding each of the ends. external parts of the surface in the direction of the center of the packaging. The package and the surface portions should preferably be positioned and folded in the process according to the invention, so that each of the bolts of a module support is positioned in a recess.
    By recess, for example means a cut or notch at the outer end of a surface portion. The positioning in the recess can be configured, on the one hand, so that the bolt is in contact at least in portions with the material of the surface portion, in particular the outer end. Also a spaced positioning of the bolts in the recess or in the notch of the material is possible without being in contact with the latter. If the bolts are used as a positioning aid in the method according to the invention for packaging an airbag, it is also possible to correct an incorrect or inaccurate positioning at the origin of the folded airbag fixed to the airbag. supporting module relative to the package, in particular moving it, before at least two surface parts are connected together in the overlap area.
    The welding can be performed by means of ultrasonic welding and / or hot welding. On the one hand, this concerns the connection of the outer ends of the surface parts to the airbag, and on the other hand, the connection of at least two surface portions to one another in the overlap area. The connection and welding, respectively, of at least two surface portions in the area of overlap with the airbag can also be achieved by said welding processes. During welding, firstly, a weld spot may lead to connecting the outer ends of the surface portions to the airbag and / or connecting at least two surface portions to each other in the overlap area. In addition, several welding points can be provided. Welding by means of a welding line or several welding lines is also possible. It can be provided in the method according to the invention that the individual welds are made successively. One can also imagine the simultaneous welding of all the overlapping areas and / or the outer ends of the surface parts on the airbag. For this purpose, an automatic welding process is preferred.
    Since the packaging and the dimensions of the package no longer have to be configured according to the dimensions of the bolts of the module holder, the packaging material can be saved above all. In addition, the method according to the invention offers the advantage that the threading or the complicated installation of a strap around the bolt is dispensed with. Since the fixing of the package is carried out directly on the folded airbag and / or on the package itself, it does not cause any state of relief, as is the case during the previous threading on the bolts of a module holder. The volume of the folded airbag is thus not unnecessarily increased. As a result, a tight package is maximized and reduced in volume of the folded airbag by the method according to the invention.
    Within the scope of another aspect, the invention is based on the idea of mentioning a packaged airbag, manufactured especially according to a previously mentioned method according to the invention. This results in advantages similar to those already explained with respect to the embodiment previously described according to the invention.
    With regard to an airbag packaged for the protection of a person, the object is further obtained by an airbag packaged for the protection of a person, in which the folded airbag is fixed a module holder and is packaged at least in parts by a package comprising at least two surface parts, characterized in that at least the outer ends of the surface portions are connected, in particular welded, to the airbag. Therefore, the folded airbag is attached to a module holder and is at least partially packaged by a package having at least two surface portions. According to the invention, at least the outer ends of the surface portions are connected, in particular welded, to the airbag.
    In a structurally simple configuration of the invention, the invention is in the form of a band. From the center of the strip, two surface areas are formed to the left and right of a tape center. The outer ends of the surface portions may be wrapped around the airbag so that the latter is wrapped in parts. The outer ends of such a strip may be connected, in particular welded, to the airbag.
    According to another independent aspect, the invention relates to an airbag packaged for the protection of a person, the folded airbag being attached to a module carrier and being at least partly packaged by a package having at least two surface parts. With regard to an airbag packaged for the protection of a person, the object is further achieved by an airbag packaged for the protection of a person, in which the folded airbag is fixed to a module carrier and is packaged at least in parts by a package comprising at least two surface parts, characterized in that at least the outer ends of the surface parts are folded towards the center of the package so that the parts surface portions are arranged to overlap at least in parts in an overlap area, the surface portions being connected, in particular welded, to each other in the overlapping zone.
    According to the invention, at least the outer ends of the surface portions are folded towards the center of the package so that the surface portions are arranged to overlap at least in portions in an overlap area, the surface portions being connected, in particular welded, to each other in the overlapping zone. This results in advantages similar to those already explained with respect to the embodiment previously described according to the invention. The airbag packaged according to the invention is characterized by a compact package and by a packaging volume as small as possible. In addition, it is no longer necessary, since the surface portions are no longer placed on the bolts, to provide a larger packing area than the required packing volume.
    In one embodiment of the invention, at least two surface portions of the package may be connected, particularly welded, to the airbag in the overlap area. Alternatively, the surface portions may be stitched and / or glued to the airbag in the overlap area.
    At least one surface portion may have a recess, in particular a cutout, at the outer end, wherein the folded airbag attached to the module support is positioned relative to the package so that at least one bolt of the module holder is positioned in a recess. The recess or cutout of the surface portion may also be referred to as a serration of the outer edge of the surface portion. Preferably said recess is formed between two extensions of the surface portion. Therefore, at least one bolt can be positioned in the recess, this being possible with or without contact with the surface portion.
    With regard to a package of an airbag for the protection of a person, particularly for a packaged airbag according to the invention, the object is further achieved by a package for a safety cushion inflatable device for the protection of a person, in particular for an airbag packaged according to any one of the points 10 to 13 defined above, the package being characterized in that it is formed with at least four surface parts forming a cross shape, wherein at least one outer end of a surface portion comprises a preferably curved and / or circular segment extension projecting from the width of the dedicated surface portion. Therefore, the package of the invention comprises at least four cross-shaped surface portions, at least one outer end of a surface portion including a preferably curved and / or circular segment-like extension. protruding from the width of the dedicated surface portion. In other words, the package is cross-shaped, with each of the four cross-shaped elements forming a surface part. In other words, the package is formed with two bands arranged in the shape of a cross.
    The outer ends of the surface portions are the end portions of the respective surface portions spaced from the center of the cross. The longitudinal axis of the surface portion is formed by a line from the center of the package to the center of the outermost edge of a surface portion. The width of a surface portion is preferably formed by a vertical relative to the longitudinal axis of the surface portion, the vertical being formed in a central region of the longitudinal axis. In other words, the vertical formed with respect to the longitudinal axis is spaced from both the center of the package and the outer edge of the surface portion. The outermost edge may be curved or straight, for example. According to the invention, at least one outer end of a surface portion comprises an extension. Such an extension may also be referred to as an additional surface tab. The extension protrudes from the width of the dedicated surface portion and widens the surface portion at the outer end.
    In addition, at least one surface portion may have two preferably curved and / or circular segmented extensions at the outer end. In this case, the two extensions protrude from the width of the dedicated surface portion.
    The symmetrical configuration of a surface portion concerning the formed extensions is advantageous since it facilitates the manufacturing process in terms of packaging. This is accompanied by a cost reduction. The axis of symmetry preferably extends perpendicular to the width of a surface portion and intersects the surface portion in the width direction. In a particularly preferred embodiment of the invention, the four surface portions are configured in the same manner, i.e. the four surface portions have the same arrangement of extensions. Preferably, the shape of the extensions is likewise configured in the same way on the four surface parts. Therefore, it is conceivable that a package according to the invention is formed axially symmetrical with respect to both a longitudinal axis and a transverse axis.
    In addition, at least one surface portion may have a recess, in particular a cutout, at the outer end. The blank may also be referred to as the serration of the material of the surface portion. Such a recess serves to position the package around a bolt. Preferably, the recess is formed between two extensions of a surface portion. The packaging can be made from polyethylene terephthalate (PET) or polyamide (PA) or polyethylene, such as high density polyethylene (PE-HD or HDPE). Uncovered PET is particularly suitable. The selection of the material for a package focuses on its ability to be welded.
    In the context of an independent aspect, the invention is based on the idea of mentioning an airbag module comprising the packaged airbag described above and / or comprising a package described above. The airbag module according to the invention further comprises an inflator for inflating the airbag. This results in advantages similar to those already explained with respect to the method described according to the invention and respectively with respect to the inflatable airbag packaged according to the invention or with respect to the package according to the invention.
    With respect to a vehicle occupant restraint system, the object is achieved by a vehicle occupant restraint system, particularly a driver airbag, comprising an airbag packaged according to the present invention. any of the points 10 to 13 previously defined and / or comprising a package according to any of the points 14 to 18 defined above and / or comprising an airbag module according to the point 19 defined above. Therefore, a vehicle occupant restraint system, particularly a driver airbag, comprises an airbag packaged according to the invention and / or a package according to the invention and / or a cushion module. inflatable safety device according to the invention. This results in advantages similar to those already explained with respect to the method described for packaging an airbag according to the invention, and / or with respect to an inflatable airbag packaged according to the invention and / or compared to a package. according to the invention and / or with respect to an airbag module according to the invention.
    Hereinafter the invention will be illustrated in detail by means of the embodiments with reference to the accompanying diagrammatic drawings. Other features and advantages of the invention will emerge more clearly from the following description taken in conjunction with these drawings, in which: FIG. 1 represents an airbag packaged according to the state of the art; FIG. 2 represents a package according to the invention; Figure 3 shows a folded inflatable airbag packaged according to the invention; and Fig. 4 shows an embodiment relating to an inflated airbag packaged according to the invention.
    Hereinafter, the same reference numbers are used for identical parts and behaving identically.
    The method relating to a packaged airbag to be manufactured according to the state of the art, as illustrated in FIG. 1, has already been explained at the beginning.
    Figure 2 shows a package 20 according to the invention for an airbag. The package comprises four surface portions 21 constituting a cross shape. The individual surface portions 21 are substantially perpendicular to each other. The lengths L of the surface portions 21 extend from the center M of the package to a respective outer edge 22 of the surface portion 21. The outer edges 22 are spaced at the maximum from the center M of the package 20.
    Two respective opposing surface portions 21, such as the upper and lower surface portions 21, are arranged axially symmetrically with respect to the longitudinal axis L extending through the left and right surface portions 21. Left and right surface portions 21 are also opposed to each other, these two surface portions 21 being arranged axially symmetrical with respect to the longitudinal axes extending through the upper and lower surface portions.
    According to Figure 2, each of the outer ends 23 of the surface portions 21 comprises two extensions 24. The extensions 24 have a curved shape. The extensions 24 protrude from the width B of the surface portions 21 related thereto. The width B is a vertical with respect to the length L of a surface portion 21. Said vertical is spaced at the same time from the outermost edge 22 and from the center M of the package 20. The extensions 24 thus widen the parts in the area of the outer end 23. The enlargement is represented by two dashed lines in the straight surface portion 21.
    The outer edges 22 of the package 20 are also curved in the example shown. This curved shape of the outer edge 22 results in a recess 25 being formed at the outer end 23. This recess 25 may also be in the form of a cutout. The recess 25 is configured between the two extensions 24. In this case, the package 20 is made from uncoated PET.
    Figure 3 illustrates an airbag 30 for the protection of a person, packaged according to the invention. The inflated airbag 31 is attached to a module support (not visible). Only the four bolts 32 of the module support stand out clearly. The packaged airbag 30 is packaged by package 20 at least in parts. In a method step (not shown), the outer ends 23 of the surface portions 21 are positioned to protrude from the airbag 30. The outer ends 23 of the surface portions 21 are then folded toward the center M of the packaging, the folded airbag secured to the module support having been positioned forward relative to the package 20.
    Two respective surface portions 21 juxtaposed are arranged to overlap at least in parts. The area of the overlap arrangement of the two surface portions 21 is designated as the overlap zone 33. The two surface portions 21 are connected, that is, welded, to each other in portions in the overlap 33. In addition, it is possible to weld the two surface portions juxtaposed and overlapping with the airbag 30 in the overlap zone 33. The overlapping areas 33 are formed by two respective extensions 24 of parts of adjacent surface 21 of the package 20.
    The recesses 25 formed at the outer end 23 are also visible in FIG. 3. The folded airbag 30 attached to a module holder is positioned relative to the package 20 so that the bolts 32 are positioned. In the recesses 25, therefore, the recesses 25 serve to aid the positioning of the package 20 with respect to the folded airbag 31 secured to the module support.
    It is obvious that the geometry of the package, in particular the length L of the individual surface portions 21, can be dimensioned independently of the length of the bolts 32. The placing of the outer ends 23 of the surface portions 21 on the bolts 32 is not necessary according to the method of the invention. The tension of the package 20 is constant throughout the packaging process so that no expansion of the packaged airbag 31 can take place.
    Since the overlap areas 33 and thus the areas of the surface portions 21 to be welded together and respectively the surface portions 21, with the airbag 31, are deployed regularly, the tension on the packaging resulting from the connection surface parts are regularly distributed. The connection or welding of the surface portions 21 in the overlap area 33 may be embodied by one or more welds.
    Figure 4 shows another embodiment of a packaged airbag 30 according to the invention. The package 20 is strip-shaped and thus comprises two surface portions 21 from the center of the strip. Each of the outer ends 23 of the surface portions 21 is folded towards the center of the package 20 so that the airbag 31 is packaged at least in parts. The outer ends 23 of the two surface portions 21 are welded together on the airbag 30. The sufficient tension is created in the package 20 by fixing the surface portions 21 between them and in addition to the airbag 30. Expansion of the packaged airbag 31 does not occur.
    In Figure 4, there is shown at least four bolts 32 of the module holder that is not visible. It is also conceivable that the outer ends 23 of the surface portions 21 are not welded together, but simply to the airbag 31. For this purpose, the package 20 may be designed to be shorter. That is, the two surface portions 21 do not need to form an overlap area. In this context, it is not necessary to place or thread a surface portion on a bolt 32, either.
