[0187] FIG. 19 shows a schematic representation of a (rectangular) gas bag and a gas generator 72. The gas generator has a gas outlet 80, which is arranged inside the gas bag (near its centre). The gas bag comprises two guiding devices 77, each having a group of guiding structures which are straight and parallel to each other. A connection 75 is provided on the gas generator to connect the gas generator to a controller (not shown).

[0188] FIG. 20 shows a schematic representation of a gas bag and a gas generator. The gas bag has a proximal section 78 close to a gas outlet of the gas generator, and a distal section 79 further away from the gas outlet. The gas bag has two guiding devices, each with a group of (preferably line-forming) guiding structures, which are straight and (slightly) diverging. A connection is provided on the gas generator to connect the gas generator to a controller (not shown).

[0189] FIG. 21 shows a schematic representation of a gas bag 71 and a gas generator 72. The gas bag 71 has short edges that extend in an X-X direction and long edges perpendicular to the short edges that extend in a Y-Y direction. The gas bag 41 further has a guiding device 77 with guiding structures which are straight and parallel to each other and which are covered by sealings 82. Furthermore, the gas bag 71 has coupling means 83 and 83 which are configured to couple the gas bag to a support element. The coupling means 83 are each provided on an associated protrusion of the gas bag 71 which protrusion projects from a section of the gas bag that is configured to be filled with gas. These protrusions may either be selected integral with one of the walls of the gas bag, or they may be attached to the (respective wall) as separate elements.

[0190] The coupling means 83 may be arranged in a contact surface 71c and a support surface 71s (as shown in the figure) or only in a support surface 71s of the airbag 71.

[0191] FIG. 22 shows a schematic representation of a cross-section of the gas bag 71 as shown in FIG. 21 along a dashed line A. While in FIG. 21 it is not recognisable whether the gas bag 71 is inflated or non-inflated, it is shown here in its inflated state. It can be seen that the gas bag is formed at least in the area of the section of the cross-section shown (at least essentially) flatly (this can also generally apply to all cross-sections not shown). The height of the gas bag extends in a direction Z-Z (which is perpendicular to the direction X-X and the direction Y-Y and is indicated by the distance of the two arrow heads) and is (considerably) smaller than a width that extends in direction X-X (here: less than 10%). It can further be seen that the guiding device 77 or its guiding structures contribute to limiting the height. The (e.g., flat) surface of the support element is not shown.

[0192] FIG. 23 shows a schematic representation of a cross-section of the gas bag 71 analogous to FIG. 22 along the dashed line A in an alternative embodiment to that shown in FIG. 22. Here too, the gas bag 71 is shown in its inflated state. The difference to FIG. 22 is that the surface of the support element is not flat, but has webs 111 and grooves 112 which are aligned with the structures of the guiding device 77 or with channels 84. Each channel 84 faces a groove 112, while each guiding structure of the guiding device faces a web 111. In this way, a sufficient gas flow can be ensured even when a certain pressure is exerted on the contact surface 71c of the gas bag 71.

[0193] FIG. 24 shows an oblique view of an impact shield according to the invention. The impact shield has a first (solid) section 58 as well as a second (softer) section 59, as well as an inner mantle 60. A gas bag (not visible) is accommodated within the inner mantle 60. The inner mantle 60 comprises tear seams 61 which are designed such that they tear open at a predetermined pressure so that the gas bag can inflate. In the first section 58A a belt guide 62 is arranged, through which a vehicle belt or a child seat belt can be passed in order to hold the impact shield (and thus the child).

[0194] An outer mantle or cover can be arranged around the inner mantle 60 (not shown in the figure).

[0195] The first section 58 is preferably made of a non-foamed plastic. The second section 59 is preferably made of a foamed plastic.

[0196] FIG. 26 shows a further embodiment of an impact shield according to the invention (in particular as component of a child seat).

[0197] The impact shield has a central impact shield section 51 as well as a gas bag 71. This can, in principle, be constructed as shown in FIG. 21 (although this is not mandatory), in particular with regard to the coupling means 83, 83 (with the specifics explained in the following).

[0198] In particular, the impact shield according to FIGS. 26-28 can have coupling means 83, which can, for example, be inserted at the place of the lower, with reference to the drawing, coupling means shown in FIG. 21. Specifically (in relation to the impact shield), these coupling means 83 (see FIG. 26) can be coupling means which are arranged at the top of the impact shield in a front third of the impact shield, in particular at a front, upper end of the impact shield (or in the vicinity thereof, for example at most 2 cm or at most 4 cm or at most 5 cm away from such a front, upper end).

[0199] These (release) coupling means 83 can be designed as shown in FIG. 27, i.e. in particular have a (dashed-drawn) predetermined tearing point and/or predetermined breaking point, which tears or breaks when a predetermined force threshold is exceeded. This predetermined tear point and/or predetermined breaking point can, for example, have one or several (e.g. at least 2 or at least 3 or at least 5, in particular arranged in a line) perforation(s).

[0200] Alternatively or additionally, a taper (as in FIG. 28) can also be provided, which also defines a predetermined tear point and/or predetermined break point. In this respect, a combination of the solution shown in FIGS. 27 and 28 is also possible. Specifically (which is not mandatory), according to the embodiment shown in FIG. 28, a pair of mutually opposite tapers is provided (where the dashed line is drawn in FIG. 27).

[0201] The force threshold is preferably predetermined such that it is (inevitably) exceeded when the airbag is triggered. However, this is not mandatory. It is also conceivable, for example, to set the force threshold higher and to take into account in this respect that an additional force may result from, for example, the fact that the child's body influences the distribution of the forces resulting from the inflation of the gas bag.

[0202] At this point, it should be noted that all the parts described above, taken individually and in any combination, in particular the details shown in the drawings, are claimed as further developments of the invention. Modifications thereof are possible.

[0203] It should further be pointed out at this point that all the parts or features described above are each on their owneven without features additionally described in the respective context, even if these have not been explicitly identified individually as optional features in the respective context, e.g. by using: in particular, preferably, for example, e.g., optionally/possibly/if necessary, round brackets etc.,or in combination or any sub-combination are to be regarded as independent embodiments or further developments of the invention, such as they are defined in particular in the introduction to the description and the claims. Deviations from this are possible. Specifically, it should be noted that the words in particular or round brackets are intended to explicitly characterise non-mandatory features in the respective context.

[0204] Finally, it is pointed out that the present application for an industrial property right (in the event of registration or grant: the present industrial property right) aims to have a protection as broad as possible. It is requested that this be borne in mind when reading, in particular in so far as (intermediate) generalisations of explicitly disclosed features or combinations of features are concerned.
