The invention relates to an airbag module for a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a motor vehicle. EP 1 555 169 A1 discloses a flexible airbag flap of an airbag module, which is arranged on a frame connected to a decorative carrier of an instrument panel and attached to the decorative carrier. US 2014 / 0 167 396 A1 discloses an airbag module. US 2008 / 0 073 885 A1 discloses an airbag device as known. Furthermore, US 5 605 347 A also discloses an airbag module. The object of the present invention is to create an airbag module for a motor vehicle and a motor vehicle with such an airbag module, so that a particularly advantageous stiffness and a particularly safe mounting of the airbag module can be achieved. This problem is solved according to the invention by an airbag module with the features of claim 1 and by a motor vehicle with the features of claim 7. Advantageous embodiments of the invention can be found in the dependent claims. A first aspect of the invention relates to an airbag module, also referred to as an airbag module, for a motor vehicle, particularly a passenger vehicle. The airbag module has a housing which includes or defines a receiving space. Furthermore, the housing or receiving space has a through-opening, also simply referred to as an opening. The housing terminates at an end face extending in a plane, the end face of which is formed, for example, by a flange of the housing. The housing can be supported via its end face on at least one further component of the motor vehicle, which is preferably separate from the airbag module and external to the airbag module, and in particular directly, such that the end face can be supported or is supported on the component, particularly directly.The end face extends at least partially, and in particular at least predominantly, around the circumference of the opening. It is conceivable that the opening is arranged at least partially, and in particular predominantly or completely, in the same plane as the end face, also referred to as the end surface. The airbag module also includes at least one airbag, also referred to as an airbag, which is in a stowed position. This means that at least one airbag component, also referred to as an airbag part, is located or contained within the receiving space or housing. To move the airbag from the stowed position to a deployment position, the airbag component must be at least partially, and in particular at least predominantly or completely, movable through the opening from the receiving space and thus from the housing. For example, the airbag component is folded or folded within the receiving space. As is well known, the airbag is a restraint element that can be moved, or is moved, from the stowed position to the deployment position, particularly in the event of a motor vehicle accident.In the restraint position, also known as the capture position, the airbag occupies a significantly larger volume in the vehicle's interior, also called the passenger compartment, compared to the stowed position. This allows, for example, an occupant in the passenger compartment to be captured and restrained by the airbag in the restraint position if they are shifted due to an accident. To move the airbag from the stowed position to the deployed position, a fluid, in particular a gas, is preferably introduced into the airbag explosively, especially by being blown in. The gas is supplied, for example, by a gas generator, particularly explosively, which allows the airbag to be moved from the stowed position to the deployed position particularly quickly, i.e., in a particularly short time. The gas generator is thus a pyrotechnic actuator, and the gas generator can be part of the airbag module. The airbag module also has at least one cover element, which is designed separately from the airbag and the housing. This cover element is also referred to as a protective cover, tensioning element, or bracing element. The cover element covers the airbag at least partially, and in particular at least predominantly or completely, on a side of the airbag facing away from the housing. The cover element is tensioned or braced against the housing by means of at least one tensioning element, which is also referred to as a bracing element. This, for example, presses the airbag against the housing. Furthermore, the airbag is compressed. This is also referred to as bracing the airbag. This prevents the airbag from unintentionally moving out of the receiving space and thus out of the housing.Furthermore, a conveniently small pack size for the airbag can be achieved because the airbag is compressed, for example, by means of the cover element. The tensioning element is hooked into the housing, thereby tensioning the cover element and, by means of the cover element, the airbag against the housing. Hooking the tensioning element into the housing is also referred to as "hooking." The aforementioned component, to which the housing can be sealed via its front face, is, for example, an instrument panel that can be or is already located in the interior of the vehicle. The cover element is thus, for example, positioned on the side of the airbag facing the instrument panel or the interior when the vehicle is fully assembled. The instrument panel has, for example, a so-called deployment channel through which the airbag moves, or unfolds, from its stowed position to its restraint position during its movement, particularly during deployment. Thus, for example, the airbag component can move through the opening in the housing and through the deployment channel, and therefore enter the passenger compartment, when the airbag is moved from its stowed position to its restraint position.The airbag module or airbag can be used in particular as a passenger airbag to catch, restrain and thus protect the passenger in the event of an accident. To achieve particularly high rigidity and a particularly secure mounting of the airbag module, the invention provides that the clamping element extends, particularly along a passage direction, through a passage channel in the housing, which opens on one side into the receiving space and on the other side into the surrounding area of ​​the housing, thereby extending under at least a portion of the end face. In other words, the clamping element, for example starting from the receiving space, passes under the portion of the end face also referred to as the end face portion and thus extends, for example, from the receiving space through the passage channel into the surrounding area of ​​the housing.This means that the clamping element is overlapped or covered by a wall section of the housing that forms at least the end face section, in the direction of the end face. In a direction away from this wall section, the passage channel is bounded, for example, by another wall section of the housing, so that this wall section forms the bottom of the passage channel. The bottom and the first wall section are spaced apart, so that the passage channel, and thus the clamping element, runs between the bottom and the first wall section. In the circumferential direction of the opening, the passage channel is bounded, for example, on both sides by lateral wall sections of the housing. Thus, for example, the first wall section projects from one of the lateral wall sections, like a balcony projects from a house wall.The clamping element runs past one side wall section and between the first wall section and the floor, so that the clamping element overlaps or is covered by the balcony in the direction of the end face section. The end face thus not only connects to the passage channel in the circumferential direction of the opening, but the end face section is also positioned above the passage channel. Consequently, the end face can be designed to be particularly large, so that it can be easily detected and subsequently monitored, especially visually and / or haptically, during the installation of the airbag module. This allows for particularly good monitoring of the airbag module installation, thus enabling a particularly effective and safe installation of the airbag module.Furthermore, the described design of the airbag module allows for a particularly high rigidity of the airbag module, especially of the housing. The invention is based in particular on the following findings: If, for example, there is a so-called protrusion of the airbag, which is formed, for example, from a fabric, so that the airbag, whose airbag part is received in the receiving space, protrudes from the receiving space and thus from the housing and thus protrudes beyond the front surface and consequently, for example, an edge formed by the front surface, in particular the upper and / or end edge, of the housing, then during the assembly of the airbag module it can usually happen that the airbag comes into contact with the front surface, especially when the airbag is tensioned by means of the cover element, i.e., stretched against the housing. In other words, with conventional airbag modules, when the airbag is tensioned using the cover element, it can happen that the airbag is tensioned against the front surface or the flange forming the front surface. If the airbag module is then connected to the instrument panel, the airbag can become trapped between the front surface and the instrument panel. This can damage the airbag, especially its fabric, negatively affect the airbag's deployment, and adversely affect the installation of the airbag module. During installation, the airbag module is screwed in place. Specifically, the airbag module is screwed to or against the instrument panel. This connects the airbag module to the instrument panel. The airbag module according to the invention reliably prevents the airbag from resting on or being tensioned against the front surface, particularly during assembly, and thus from becoming trapped between the instrument panel and the housing. This allows for a particularly safe installation. Simultaneously, a previously described airbag overhang can be permitted or implemented, although, due to the described design of the airbag module according to the invention, even with such an overhang, the airbag does not rest on the front surface. Furthermore, the front surface and, for example, the flange of the housing forming the front surface can be monitored during the installation of the airbag module. This allows for monitoring of the assembly sequence and during the assembly process.For example, the front surface is optically detected by means of at least one camera and / or at least one scanner and / or at least one laser and / or another detection element. Alternatively or additionally, the front surface can be detected, for example, haptically, and in particular by means of at least one push button. Since the assembly of the airbag module can be reliably monitored by the inventive design of the airbag module, the aforementioned protrusion, also referred to as package overhang, can be safely implemented, i.e., permitted or realized, without damaging the airbag during assembly, without negatively affecting its deployment, and without negatively impacting the assembly of the airbag module. It is provided that the clamping element, extending along the passage direction through the passage channel of the housing, extends under a second part of the end face, whereby the clamping element overlaps or is covered by a second wall section of the housing, which forms at least the second part of the end face, in the direction of the second part of the end face. The second part of the end face is also referred to as the second end face section. A slot is arranged circumferentially around the opening between the first wall section and the second wall section, which opens into the passage channel, particularly towards the bottom, with the slot being arranged circumferentially around the opening between the end face sections.This allows for a particularly safe assembly or manufacture of the airbag module, since, for example, the clamping element, which may initially be located completely outside the passage channel, can be guided through the slot and thus moved into the passage channel, in particular threaded in. Alternatively or additionally, the aforementioned airbag protrusion is provided. This means that the airbag, in its stowed position, penetrates the opening and thus protrudes beyond the opening from the receiving space and the housing. The airbag therefore has at least a second airbag component, which is connected to the first airbag component, in particular, formed integrally with the first airbag component. The second airbag component is located outside the receiving space and thus outside the housing, so that the second airbag component protrudes from the housing. In other words, the second airbag component, for example, extends beyond the front face or the aforementioned upper edge of the housing formed by the front face. This protrusion, also referred to as the package extension, allows for a particularly advantageous installation and function of the airbag module.As previously described, it is conceivable that the additional component is supported, particularly directly, on the end face, or vice versa. For example, an end face of a channel wall in the instrument panel that defines the firing channel is supported, particularly directly, on the end face. The raised section of the airbag assembly makes it possible to achieve a particularly long or high firing channel in the instrument panel. Consequently, particularly long screws can be used to bolt the housing to the instrument panel. In return, the airbag module according to the invention can be made somewhat lower in height compared to conventional solutions. In the fully manufactured state of the vehicle, the raised section of the airbag assembly, or the airbag itself, particularly the second airbag component protruding from the housing, is designed to project into or be arranged within the firing channel.This design ensures, on the one hand, that the airbag module is securely bolted to the instrument panel. On the other hand, the airbag can be guided safely and precisely through the firing channel during its deployment, i.e., during its movement into the restraint position, thus ensuring a particularly advantageous deployment. Alternatively or additionally, the clamping element is designed to engage behind the further wall area of ​​the housing that defines the passage channel in the direction away from the end face and the first wall area. This ensures, for example, that the clamping element is particularly firmly connected to the housing, especially in a snap-fit ​​manner, so that the cover element can be clamped securely against the housing using the clamping element. In an advantageous embodiment of the invention, the clamping element is covered by the wall area over its entire width, particularly in the circumferential direction of the opening, towards the end face portion. This means that the passage channel is completely enclosed and thus closed by the wall area along its entire width in the circumferential direction of the opening towards the end face or end face portion. This allows for particularly high rigidity. It is preferably intended that the first wall section and the second wall section are formed in one piece. This allows for a particularly high stiffness to be achieved. The feature that the cover element is tensioned against the housing by means of the tensioning element does not necessarily imply that the cover element directly touches the housing, i.e., is directly tensioned against it. The feature that the cover element is tensioned against the housing by means of the tensioning element can be understood, in particular, to mean that a tensioning force acting specifically on the cover element is realized by means of the tensioning element, which, for example, points from the tensioning element towards the housing, wherein, for example, the cover element is supported against the housing, particularly against the tensioning force, via the tensioning element and / or via the airbag, and is thus tensioned against the housing by means of the tensioning element and / or by means of the airbag. It is particularly conceivable that the cover element, especially a side of the cover element facing the airbag and the housing, directly touches the airbag. To achieve particularly safe mounting and function of the airbag module, a further embodiment of the invention provides that a covering area of ​​the cover element, which at least partially, and in particular at least predominantly or completely, covers the airbag on its side facing away from the housing, extends in a further plane parallel to the plane in which the end face extends and is spaced apart from that plane. Particularly when the aforementioned package extension is provided, the further plane does not intersect the receiving space. The airbag can thus be held particularly compactly by means of the cover element, and the package extension can be represented particularly advantageously. In order to achieve particularly high rigidity and particularly good assembly, a further embodiment of the invention provides that the clamping element is formed integrally with the cover element. Finally, achieving particularly high rigidity has proven advantageous if the housing is manufactured in one piece. For example, the housing is made of a plastic. Furthermore, it is conceivable that the housing is manufactured by injection molding, especially plastic injection molding. A second aspect of the invention relates to a motor vehicle, preferably designed as a passenger car, which has at least one airbag module according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention and vice versa. Details of the invention will become apparent from the description of the figures and the drawings. Here, Fig. 1 shows a schematic perspective view of an airbag module according to the invention; Fig. 2 shows a partial schematic perspective view of the airbag module; Fig. 3 shows a schematic sectional view of the airbag module along a section line AA shown in Fig. 2; and Fig. 4 shows a schematic top view of the airbag module. Fig. 1 shows a schematic perspective view of an airbag module 1, also referred to as an airbag module, for a motor vehicle, in particular a passenger car. The airbag module 1 has a housing 2, also referred to as a module housing or airbag module housing, which has, defines, or forms a receiving space 4 as shown in Fig. 3. As can be seen particularly well in conjunction with Fig. 2 and Fig. 4, the housing 2 terminates at an end face 5 of the housing 2 extending in a virtual or imaginary plane. In this case, the end face 5 is formed at least partially, in particular predominantly or completely, by a collar 6 of the housing 2.In the fully manufactured state of the motor vehicle, the housing 2 is supported via the end face 5 and thus via the flange 6 on an instrument panel of the motor vehicle, which is formed separately from the airbag module 1 and, in particular, external to the airbag module 1, in such a way that the end face 5 directly contacts the instrument panel, especially an inner side of the instrument panel facing away from the interior of the motor vehicle. The end face 5 and thus the flange 6 form an end edge 7 of the housing 2, also referred to as the upper edge, wherein, for example, the housing 2 and thus the receiving space 4 terminate at the end edge 7. Furthermore, it is conceivable that the end face 5 terminates at the end edge 7. The housing 2 and the receiving chamber 4 have an opening 8 (Fig. 3), also referred to as a through-opening, which opens into the receiving chamber 4 at one end and into a surrounding area 9 of the housing 2 at the other end. The end face 5 extends at least partially, and in particular at least predominantly, around the opening 8 in the circumferential direction. The airbag module 1 also has an airbag 10, also referred to as an airbag, which is in a stowed position. The airbag 10 is, for example, folded. As can be seen in Fig. 3, the airbag 10 has at least one, and in particular a predominant, airbag component 11 arranged or received in the receiving chamber 4. This means, in particular, that more than half of the airbag 10 is received in the receiving chamber 4. In order to catch and restrain a person inside the vehicle, such as the front passenger, in the event of an accident using the airbag 10, a gas generator, designed as a pyrotechnic actuator, provides a gas, particularly in an explosive manner. The gas is introduced into the airbag 10, causing it to inflate. This moves the airbag 10 from its stowed position, as shown in the figures, to a restraint position. In the restraint position, the airbag 10 occupies a larger volume in the vehicle interior than in the stowed position. During the movement of the airbag 10 from the stowed position to the restraint position, it is at least partially moved through a so-called deployment channel in the instrument panel and thus through the instrument panel and into the vehicle interior.In this process, the airbag component 11 is at least partially moved out of the receiving space 4 and thus out of the housing 2 via the opening 8. During its movement from the stowed position to the deployment position, the airbag 10, for example, inflates. The airbag 10 is, for example, flexible and is made of a particularly flexible textile, especially a flexible fabric. The airbag module 1 also has a cover element 12, which is formed separately from the housing 2 and preferably also separately from the airbag 10. This cover element is also referred to as a protective cover. Preferably, the protective cover is made of the same textile, in particular the same fabric, as the airbag 10. The cover element 12 covers the airbag 10 at least partially, in particular at least predominantly or completely, on a side 13 (Fig. 3) of the airbag 10 facing away from the housing 2. Furthermore, the airbag module 1 comprises tensioning elements 14, which are also referred to as tensioning elements, tensioning tabs, or tensioning tabs. By means of the tensioning elements 14, the cover element 12 is tensioned against the housing 2 such that the cover element 12 is tensioned against the airbag 10 by means of the tensioning tabs and, via the airbag 10, against the housing 2. For example, the cover element 12 is supported on the housing 2 via the airbag 10.Furthermore, the cover element 12 is directly supported on the airbag 10, in particular on its side 13, so that, for example, the cover element 12 touches the side 13. The tensioning elements 14 are, for example, formed separately from the cover element 12 and connected to the cover element 12. It is also conceivable that the tensioning elements 14 are formed integrally with the cover element 12. The tensioning elements 14 are, for example, hooked and / or latched to the housing 2 and / or otherwise connected to the housing 2, such that the cover element 12 is tensioned or held against the airbag 10 by means of the tensioning elements 14 and, via the airbag 10, against the housing 2. Furthermore, the airbag module 1, in particular the housing 2, has fastening elements 15 by means of which the housing 2 can be attached to the instrument panel. In the embodiment shown in the figures, the respective fastening element 15 is designed as a through-hole, also known as a screw hole, screw opening, or screw hole, through which, for example, a screw element, in particular designed as a screwdriver, can be inserted. By means of the screw element, the housing 2 is screwed to the instrument panel and thereby attached to the instrument panel, or vice versa. It is particularly evident from Fig. 1 that the respective fastening element 15 is formed in the collar 6 and thus penetrates the collar 6 and the end face 5, in particular completely. In order to achieve particularly advantageous rigidity and a particularly secure mounting of the airbag module 1, which, for example, is mounted in such a way that the housing 2 is attached to the instrument panel by means of the fastening elements 15, the respective clamping element 14 extends along a passage direction illustrated in Fig. 3 by a double arrow 16 through a respective passage channel 17 of the housing 2, which opens on the one hand into the receiving space 4 and on the other hand into the surroundings 9, and thereby under at least a respective part T1 of the end face 5, whereby the respective clamping element 14, in particular its length region L (Fig. 3) extending through the passage channel 17, is overlapped or covered in the direction of the respective part T1 of the end face 5 by a wall region W1 of the housing 2 which forms at least the respective part T1. As can be seen particularly well in Fig. 3, the passage channel 17 is bounded, in particular completely, by a further wall section W3 of the housing 2 in a direction pointing away from the wall section W1, so that the wall sections W1 and W3 are spaced apart from each other, such that the passage channel 17, and thus the clamping element 14, in particular the length section L, extends between the wall sections W1 and W3, in particular along the passage direction. The wall section W3 is also referred to as the bottom. In the circumferential direction of the opening 8, the respective passage channel 17 is bounded on both sides by lateral wall sections spaced apart from each other in the circumferential direction of the opening 8. With reference to the passage channel 17 visible in Fig. 3, one of the lateral wall sections is visible in Fig. 3 and is labelled 18 there. The wall area W1 projects from the wall area 18, similar to how a balcony projects from a house wall, so that the respective wall area W1 is also referred to as a balcony. Thus, the respective wall area W1 is, for example, a balcony formed on the housing 2. The balconies, and the fact that the clamping elements 14 extend under the balconies and thus under the end face, prevent the clamping elements 14 used to tension the cover element 12 from covering parts of the end face 5. This allows, for example, the end face 5 to be particularly well detected and monitored, especially visually and / or haptically, during the installation of the airbag module 1, thus enabling particularly good monitoring of the installation process. In particular, it is conceivable that the respective clamping element 14 extends from the receiving space 4 through the passage channel 17 to the surrounding area 9. As can be seen particularly well in Fig. 4, the respective clamping element 14 also extends under a respective second part T2 of the end face 5, whereby the clamping element 14 is overlapped or covered in the direction of the respective second part T2 of the end face 5 by a respective second wall region W2 of the housing 2, which forms at least the second part T2 of the end face 5. A slot S is arranged in the circumferential direction of the opening 8, the circumferential direction of which is illustrated in Fig. 4 by a double arrow 19, between the wall regions W1 and W2 and thus between the parts T1 and T2 of the end face 5, by means of which the parts T1 and T2, and thus the wall regions W1 and W2, are spaced apart from each other. The slot S opens, for example, on one side into the passage channel 17 and on the other side to the surroundings 9.Thus, for example, during the assembly of the airbag module 1, the respective clamping element 14, in particular its length L, can be moved through the slot S relative to the housing 2, thereby moving the clamping element 14, in particular its length L, into the passage channel 17, in particular threading or inserting it. It is conceivable that the slot S is not provided, so that, for example, the clamping element 14, in particular its length L, is then covered over its entire width towards part T1 by the wall area W1. In the embodiment shown in the figures, the housing 2 is formed in one piece, so that the wall sections W1 and W2 are formed integrally with each other. Furthermore, it is provided that the wall section W3 is formed integrally with the wall section W1 and / or with the wall section W2. In addition, the clamping element 14 engages behind the base (W3), whereby the clamping element 14, and via it the cover element 12, is particularly advantageously clamped against the housing 2. Figures 1, 3, and 4 clearly show that a covering area AB of the cover element 12, which at least partially, and in particular at least predominantly or completely, covers the airbag 10 on its side 13 facing away from the housing 2, and which is at least substantially planar, extends in a further plane spaced apart from the aforementioned plane and running parallel to it. Furthermore, the airbag module 1 has a projection of the airbag 10, also referred to as a package protrusion. This means that the airbag 10 penetrates the opening 8 and thus protrudes from the receiving space 4 and the housing 2, and consequently extends beyond the end face 5.Thus, a second airbag part 20 of the airbag 10, connected to the airbag part 11, and in particular formed integrally with the airbag part 11, is arranged outside the receiving space 4 and therefore outside the housing 2 itself, with, for example, the cover element 12 directly abutting or being supported against the second airbag part 20. In other words, the end face 5 is set back from the airbag part 20. This allows the aforementioned screws to be made particularly long. In the fully manufactured state of the motor vehicle, the airbag part 20 is, for example, arranged in the firing channel of the instrument panel. The balconies formed in the housing 2, which is preferably made of plastic, prevent the airbag 10, and in particular its protective fabric, from being pulled over the collar 6 of the housing 2. This prevents the airbag from getting between the collar 6 and the instrument panel and thus from becoming trapped between them. Figure 4 shows that the tensioning elements 14, and thus the balconies and the bracing effect achieved by means of the tensioning elements 14 and the balconies, are provided on only one of the four sides of the housing 2, this one side being designated S1 in Figure 4. It is, of course, possible for the bracing to be arranged on two of the four sides, on three of the four sides, or on all four sides. Furthermore, it is alternatively or additionally conceivable that the bracing is bonded in place.In other words, it is conceivable that the respective clamping element 14 is bonded to the housing 2. The respective clamping element 14 can be formed separately from the cover element 12 and connected to the cover element 12, or the respective clamping element 14 can be formed integrally with the cover element 12. It is particularly evident from Fig. 4 that the collar 6 and the end face 5 are not obscured in any area and can therefore be detected and thus inspected using various methods. For example, the collar 6 and thus the end face 5 can be detected and subsequently monitored or inspected using at least one camera, at least one sensor, at least one scanner, at least one laser, and / or at least one other detection element.
