Furthermore, DE 42 31 050 A1 discloses a belt retractor.It is the object of the invention to create an arrangement of a vibration damper on a structural element of a seat system of a motor vehicle, so that the weight and / or production outlay of the motor vehicle can be kept particularly low.This object is achieved according to the invention by an arrangement of a vibration damper on a structural element of a seat system of a motor vehicle having the features of patent claim 1. Advantageous embodiments of the invention are the subject matter of the dependent claims and the description.The invention relates to an arrangement of a vibration damper on a structural element of a seat system, in particular on a backrest of the seat system, of a motor vehicle. The motor vehicle is designed, for example, as a motor vehicle, in particular as a passenger car, utility vehicle or as a truck. The vibration absorber can be referred to in particular as an absorber.The vibration damper can be part of the seat system or the vibration damper can be formed separately from the seat system. Preferably, the motor vehicle, in particular in its completely manufactured state, has the seat system, and in particular the vibration damper.The seat system can be understood to mean, in particular, a vehicle seat of the motor vehicle. The vehicle seat has at least one surface, which is designated in particular as a seat surface and is designed for seating at least one vehicle occupant, in particular during a journey of the motor vehicle. In other words, the vehicle occupant can sit on the seat system. The seat system is preferably arranged in an interior of the motor vehicle. The interior space can be referred to in particular as a passenger space or as a passenger space. The backrest of the seat system is preferably designed as a backrest. The backrest preferably has at least one backrest surface on which a back of a vehicle occupant seated on the seat contact, in particular the seat surface, can be supported, in particular directly.The vibration damper has at least one damper mass for damping or damping vibrations of the seat system, in particular of the structural element and / or of the backrest. In other words, the oscillation of the seat support, in particular of the structural element and / or of the backrest, can be damped or tilgated, in particular in a targeted manner, by means of the damper mass. This means in particular that the vibration damper suppresses or dampens vibration inputs of the seat system or into the seat system by means of a mass which is referred to in particular as damper mass. Thus, because the vibration damper is arranged on the structural element of the seat system, the vibrations of the seat system, in particular of the structural element, are preferably at least lower than if the vibration damper were not arranged on the structural element or the motor vehicle, in particular the seat system, were free of the vibration damper.The damper mass is held at least indirectly, in particular directly, preferably movably, for example elastically, on the structural element via at least one bearing device. In other words, the damper mass is fastened or arranged via the bearing device or by means of the bearing device, in particular movably or flexibly, on the structural element, in particular at least indirectly or directly. The fact that the damper mass is held on the structural element so as to be movable at least indirectly via the bearing device can be understood in particular to mean that the damper mass is held on the structural element so as to be movable at least indirectly, in particular directly, via the bearing device relative to the structural element, in particular in a translatory and / or rotary manner. The bearing device is, for example, part of the vibration damper. Alternatively, the bearing device can be formed separately from the vibration damper. The bearing device can be part of the seat system or can be formed separately from the seat system.The vibration damper can be understood in particular as a vibration damper. For example, a natural frequency of the vibration damper, in particular of the damper mass, is tuned, preferably in a targeted manner, to a resonant frequency of the seat system, in particular of the structural element or of the backrest, which resonant frequency is to be eliminated or to be damped. This means that when the vibration damper, in particular the damper mass, is excited with its natural frequency via the structural element, the seat contact, in particular the structural element or the backrest, then carries out only particularly low vibrations, in particular movements. The damper mass is thus designed in particular for specifically damping or damping the oscillations of the seat system, in particular of the structural element or the backrest.For example, the vibration damper has at least one spring-mass system which is formed by the damper mass and a damper spring, which is formed in particular separately from the damper mass. A natural frequency of the spring-mass system is preferably set to the resonant frequency or oscillation frequency of the seat system, in particular of the component or the backrest, which is to be eliminated or to be damped. In particular, the vibration damper can draw vibration energy for its own vibration movements at its natural frequency or in the region of its natural frequency of the seat system, in particular of the component or of the backrest, wherein the vibration energy can be converted into heat by friction.In order to be able to keep weight and / or production outlay, in particular production costs, of the motor vehicle, in particular of the seat system, particularly low, it is provided according to the invention that the damper mass is formed at least by at least one component of a belt tightening device for a seat belt, which is provided in particular for the seat system. In other words, the damper mass is designed at least as a component part of the belt tightening device. This means that the damper mass is designed, in particular at least partially or completely, as the, in particular completely, belt tightening device or as a part of the belt tightening device. In other words again, the damper mass is designed, in particular at least partially or completely, as a component which is designed or provided as a, in particular complete, belt tightening device or as part of the belt tightening device. This means that the belt tightening device or at least the component part of the belt tightening device is used as the damper mass, i.e. is used as a damper. In particular, at least a part of the belt tensioning device is thus part of the vibration damper.The belt tensioning device can be referred to in particular as a belt tensioner or as a retractor. For example, the belt tensioning device is part of an, in particular active, safety system of the motor vehicle. By means of the belt tensioning device, in particular in the event of an accident of the motor vehicle, the seat belt can be tightened, in particular so that the vehicle occupant sitting on the seat system, in particular the seat surface, can participate earlier or particularly early in an overall deceleration of the motor vehicle. Tightening the seat belt can be understood in particular as tightening the seat belt. Preferably, at least one force, in particular a tensile force, can be provided or exerted by means of the belt tensioning device in order to tighten or tighten the seat belt. In other words, the seat belt can be acted upon with the force by means of the belt tensioning device for tensioning or tightening the seat belt. The force can be brought about by means of the belt tensioning device, for example by means of a spring or pyrotechnically, that is to say, for example, by means of a small explosive charge. The belt tensioning device can have at least one belt force limiting device, which is referred to in particular as a belt force limiter.For example, the belt tensioning device has at least one housing element. Preferably, at least one length region of the seat belt is arranged within the housing element and in particular, for example movable relative to the housing element, guided within the housing element. Thus, the housing element delimits, for example, at least one receiving space in which at least the longitudinal region of the seat belt can be arranged or arranged, in particular guided or guided.For example, at least one belt rolling device, which is referred to in particular as a belt retractor, is provided. By means of the belt retractor or on the belt retractor, the seat belt can be at least partially rolled up or rolled up, in particular the length region of the seat belt. For example, the belt retractor has at least one roller for rolling up the seat belt. In particular, by rotating the roller about an axis of rotation of the roller, the seat belt can be wound up on the roller and / or can be unrolled from the roller. For example, the belt retractor, in particular the roller, is arranged within the housing element or in the receiving space. The belt retractor, in particular the roller, can be part of the belt tensioning device.The component of the belt tightening device can be understood in particular as an individual component of the belt tightening device or an, in particular multi-part, assembly of the belt tightening device. For example, the component is designed as the belt retractor, in particular the roller, and / or the housing element.The seat belt can be understood to mean, in particular, a restraint system of the motor vehicle, in particular the seat system, which is designed as a belt. The seat belt can be referred to in particular as a seat belt. In particular, by means of the seat belt, forward displacement of the vehicle occupant, in particular seated on the seat system, can be prevented or prevented, for example during an accident of the motor vehicle and / or in the event of deceleration of the motor vehicle. The forward displacement can be understood in particular to mean a movement of the vehicle occupant in the vehicle longitudinal direction that runs forward relative to the seat system, in particular the backrest and / or the seat surface. For example, the motor vehicle, in particular the seat system, has at least one seat belt system which has at least the seat belt and the belt tensioning device. The seat belt, in particular the seat belt system, can be part of the seat system or can be formed separately from the seat system.The invention is based in particular on the following findings and considerations: seat systems which are designed, for example, as integrated seat belts can have a particularly heavy backrest, for example, on account of a belt integration. This can lead to natural frequencies of the seat system, in particular of the backrest, wherein these natural frequencies can strike a vehicle excitation. Alternatively or additionally, a belt machine can be located on the backrest, which can lead to natural frequencies which the vehicle excitation impinges. The vehicle excitation can be understood in particular as an excitation of a body of the motor vehicle. This means in particular that oscillations of the body, in particular in the region of the natural frequency of the seat system or of the backrest, can excite the seat system or the backrest, that is to say can be transmitted to the seat system or the backrest. Vibrational excitations of the seat system, in particular of the backrest, can have a negative effect on comfort of the motor vehicle. In principle, it is conceivable, in particular for reducing the oscillations of the seat system, in particular of the backrest, to increase the natural frequency of the seat system or of the backrest, for example, by means of massive reinforcing measures, which, however, can lead to an increase in production costs and / or weight. Alternatively or additionally, it is conceivable to use a conventional, separate vibration damper, which can likewise lead to an increase in weight and / or to an increase in production costs. In other words, an additional conventional damper can mean increases in weight and / or costs of the motor vehicle, in particular of the seat system.In contrast, in the arrangement according to the invention, the belt tightening device or at least the component part of the belt tightening device is used as a vibration damper, in particular as a damper mass. This means that no additional vibration damper is to be provided, but rather an already present component in the form of the belt tightening device or of the at least one component of the belt tightening device can be used as damper mass for damping the vibrations. In particular, because no additional or separate vibration damper is to be provided, the weight and / or production outlay, in particular production costs, of the motor vehicle, in particular of the seat system, can be kept particularly low, for example with simultaneous securing or increasing of the comfort, in particular driving comfort, of the motor vehicle. By damping or cancelling the oscillations by means of the oscillation damper, the comfort, in particular the driving comfort, of the motor vehicle can be particularly improved. As a result, a journey of the motor vehicle can be made particularly comfortable for the vehicle occupant. By means of the bearing device, a suspension of the damper mass on the structural element can be effected, wherein this suspension allows a vibration of the damper mass, in particular relative to the structural element, in order to cancel the vibrations, in particular in the region of the natural frequency. In this case, safety requirements, preferably for dynamic and / or static load cases, can be met particularly reliably, in particular simultaneously.Furthermore, it is provided that the bearing device is formed at least in regions, in particular predominantly or completely, from at least one elastic material. In other words, the bearing device is at least partially, in particular completely, elastic. The elastic material can be understood to mean, in particular, an elastic material. As a result, the damper mass can be held on the structural element so as to be movable at least indirectly, in particular directly, by elastic deformation of the bearing device relative to the structural element, in particular in order to cancel or damp the oscillations by the movement or the elastic deformation. This means that the damper mass is, for example, elastically suspended via the bearing device, in particular so that the damper mass or the retractor can oscillate. Because the bearing device is formed at least in regions from the elastic material, the movement or the oscillation of the damper mass can be realized with particularly low outlay, in particular particularly reliable. As a result, the oscillations can be cancelled by means of the oscillation damper with particularly low outlay, and in particular particularly reliably. Furthermore, it is provided that the elastic material is a plastic. In other words, the bearing device is formed at least in regions, in particular completely, from the plastic. As a result, the oscillations can be cancelled particularly low in terms of complexity and / or particularly reliably. Furthermore, the vibration damper, in particular the seat system and / or the motor vehicle, can be produced with particularly low cost, in particular particularly cost-effective. For example, the plastic is an elastomer.Alternatively or additionally, it is provided that the damper mass has at least one first connecting means and at least one second connecting means, in particular formed corresponding to the first connecting means, is provided on the structural element. The second connecting means can be part of the component, that is to say the component can have the second connecting means. Alternatively, the second connecting means can be formed separately from the component and can be arranged, in particular at least indirectly or directly, on the component, in particular can be connected to the component. Furthermore, it is provided that by means of the connecting means, by forming a positive connection, in particular between the damper mass and the structural element, the movement of the damper mass relative to the structural element can be prevented or prevented, for example in the event of an accident of the motor vehicle. In other words, a, in particular at least indirectly or directly, positive connection of the damper mass to the structural element can be effected or brought about via the connecting means, wherein, when the positive connection is effected or formed, the movement of the damper mass relative to the structural element is omitted, that is to say is not possible. Again in other words, the damper mass can be connected or connected immovably, at least indirectly, in particular directly, to the structural element via the connecting means by forming the positive connection relative to the structural element. As a result, the movement of the damper mass relative to the structural element can be prevented in a particularly low-expenditure and / or particularly reliable manner, for example in the event of an accident of the motor vehicle. This makes it possible, for example, to ensure that the seat belt system, in particular the belt tensioning device, functions reliably in the event of an accident. In other words, a safety of the motor vehicle, which is referred to in particular as vehicle safety, can be particularly increased. The form-fitting connection is designed, for example, as a clamping connection.The connecting means make it possible, for example, to dispense with an additional securing device for securing the function of the seat belt in the event of an accident of the motor vehicle. As a result, manufacturing complexity, in particular manufacturing costs, and / or weight of the motor vehicle, in particular of the seat system, can be kept particularly low. In particular, because one of the connecting means is part of the damper mass, an additional, further connecting means formed separately from the damper mass can thus be dispensed with.In a further embodiment, it is provided that the structural element is designed as a frame element of the seat system, in particular of the backrest. In other words, the vibration damper is arranged, in particular at least indirectly or directly, on the frame element and is held, in particular, at least indirectly on the frame element via the bearing device. As a result, oscillations of the frame element can be particularly well absorbed or damped by means of the oscillation damper, in particular the damper mass, as a result of which, in particular, comfort can be particularly increased. Furthermore, the damper mass can be arranged or held particularly securely on the seat system. The frame element can be referred to in particular as a backrest frame. The frame element can be understood to mean, in particular, a supporting structure of the seat system, in particular of the backrest.In a further embodiment, it is provided that the bearing device has at least one spring element, by means of which the damper mass is held at the structural element at least indirectly elastically, in particular movable relative to the structural element. In other words, the damper mass is coupled to the structural element elastically or movably at least indirectly, in particular directly, via the spring element. As a result, the movement or oscillation of the damper mass relative to the structural element can be effected in a particularly low-complexity and / or particularly reliable manner. The oscillations can thus be cancelled by means of the oscillation damper in a particularly low-expenditure and / or particularly reliable manner. The spring element is formed from a metal, for example. For example, the spring element is designed as a helical spring and / or as a helical spring. For example, the spring element is designed as a tension spring, as a bending spring or as a torsion spring.For example, the spring element is the elastic material. Alternatively, the spring element is provided in addition to the elastic material formed from the plastic, for example. The bearing device can thus comprise the, in particular elastic, spring element and / or the elastic material formed, for example, from plastic.In a further embodiment, it is provided that the seat contact is designed as an integral seat for the belt. In other words, the seat system has the seat belt, in particular the seat belt system, and in particular the belt tensioning device. In particular because the seat of the belt integral seat can be particularly heavy as a result of the belt integration, the comfort can be increased in a particularly low-complexity manner, in particular in a particularly weight-saving and / or particularly cost-effective manner, by means of the arrangement according to the invention. The arrangement according to the invention is thus particularly advantageous in particular for an integral seat of the belt.The belt integral seat can be understood in particular as a seat system which provides or brings about both a seat function for the vehicle occupant and a function with respect to the seat belt, in particular for the vehicle occupant. The belt integral seat preferably has at least one receiving region, within which at least the longitudinal region of the seat belt is arranged. The receiving region can be understood in particular as a receiving space which is bounded at least partially, in particular completely, by at least one wall of the seat system. For example, the belt tensioning device is arranged at least partially, in particular completely, within the receiving region.In a further embodiment, it is provided that the connecting means, in their installed position provided in the motor vehicle, are located in a first position relative to one another, in which the damper mass is movable relative to the structural element. In other words, the damper mass is held on the structural element so as to be movable at least indirectly relative to the structural element via the bearing device in the first position. This means that the movement of the damper mass relative to the structural element in the first position is possible, in particular because the movement or movability is or is released by the connecting means. The installation position of the connecting means carried out in the motor vehicle can be understood to mean, in particular, a normal position of the connecting means, in particular relative to one another. In particular, the connecting means are in the first position before the accident of the motor vehicle, or if the accident of the motor vehicle fails or does not take place. Therefore, the first position can be understood to mean, in particular, an accident-free position.Preferably, the connecting means are movable, in particular relative to one another, as a result of an accident-induced movement of the damper mass relative to the structural element, in particular from the first position into a second position which is different from the first position. In other words, in the event of the accident of the motor vehicle, the connecting means can be moved or displaced relative to one another, in particular from the first position, into the second position. The accident-related movement of the damper mass relative to the structural element can be understood to mean, in particular, a movement of the damper mass relative to the structural element during the accident of the motor vehicle, wherein this movement is preferably or can be effected by the accident, in particular by at least one accident-related force and / or at least one accident-related torque. In the second position, the movement of the damper mass relative to the structural element is preferably prevented or can be prevented by forming the positive connection. This means that in the second position the form-fitting connection is formed or is present. In particular, the form-fitting connection is not formed in the first position. This means that the positive connection is preferably formed exclusively in the second position with respect to the first and the second position. In other words, in the second position, the damper mass and the structural element are connected to one another at least indirectly, in particular directly, in a form-fitting manner, in particular immovably relative to one another, via the connecting means.For example, the connecting means are spaced apart from one another in the first position. Preferably, the connecting means are not spaced apart from one another in the second position, but rather abut one another, in particular directly. The movement of the connecting means relative to one another can be understood in particular to mean a movement of the first connecting means relative to the second connecting means and / or a movement of the second connecting means relative to the first connecting means.For example, the connecting means can be moved, in particular from the first position, into the second position if the relative movement of the connecting means with respect to one another or the movement of the damper mass relative to the structural element is greater than a, in particular predefined, reference movement. This means that the form-fit connection is formed in particular when the movement of the damper mass relative to the structural element is greater than the, in particular predefined, reference movement. The reference movement can be understood in particular to mean a maximum permissible movement.Overall, it can be seen that the damper mass can be connected positively to the structural element, for example, when the damper mass oscillates unintentionally strongly in the event of the accident or moves differently than desired, in particular by means of clamping. Thus, clamping of the damper mass can be effected in order to fix the damper mass. The movement of the connecting means into the second position can be effected, for example, by a particularly strong tensile load acting on the seat belt. The form-fit connection makes it possible to ensure the function, in particular the restraining function, of the seat belt particularly reliably even in the event of a crash. In particular, it can be ensured that, in particular, defined belt points of the seat belt are in their intended or correct position. As a result, the safety of the motor vehicle, in particular for the vehicle occupant, can be particularly increased.For example, it is provided that one of the connecting means is designed as a receiving opening and the other of the connecting means is designed as a receiving element, in particular designed corresponding to the receiving opening, which can be arranged or received in the receiving opening, in particular directly, for forming the positive connection. In other words, the receiving element, in particular with respect to the first and the second position exclusively, is arranged or received in the receiving opening in the second position. In other words again, the receiving element, in particular in the second position, can be engaged or engaged in the receiving opening. As a result, the form-fitting connection can be effected in a particularly low-expenditure and / or particularly reliable manner. The receiving element is designed, for example, as a nose. This means that the receiving element protrudes from a base body of the damper mass, for example.Further features of the invention are evident from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or alone.The invention will now be explained in more detail on the basis of a preferred exemplary embodiment and with reference to the drawings. The following are shown: FIG. 1 shows a schematic perspective view of an arrangement according to the invention of a vibration damper on a structural element of a seat system; and FIG. 2 shows a schematic side view of an arrangement according to the invention of a vibration damper on a structural element of a seat system; and FIG. 3 shows a schematic side view of an arrangement according to the invention of a vibration damper on a structural element of a seat system according to a further embodiment; and FIG. 4 shows a schematic partial view of an arrangement according to the invention of a vibration damper on a structural element of a seat system according to a further embodiment; and FIG. 5 shows a schematic partial sectional view of an arrangement according to the invention of a vibration damper on a structural element of a seat system according to a further embodiment.In the figures, identical or functionally identical elements are provided with identical reference symbols.FIG. 1 shows a schematic perspective view of an arrangement 1 of a vibration damper 2 on a structural element 3 of a seat system 4 of a motor vehicle. FIG. 2 shows the arrangement 1 in a schematic side view. In particular, FIGS. 1 and 2 show the seat system 4 in each case in a schematic partial view.As shown by way of example in FIG. 1, the seat system 4 preferably has at least one seat part 5. The seat part 5 has, for example, at least one cushion. In particular, the seat part 5, in particular the cushion of the seat part 5, has at least one seat surface 6, which is designed for seating a vehicle occupant. The seat surface 6 is, for example, a surface which points upwards at least substantially in the vehicle vertical direction 7 of the motor vehicle.As shown by way of example in FIG. 1, the seat system 4 preferably has at least one backrest 8, in particular backrest. The backrest 8 preferably has at least one backrest part 9. The backrest part 9 is covered, for example, by a cushion of the backrest 8, in particular at least partially or completely. The seat part 5 and the backrest 8, in particular the backrest part 9, can be formed separately from one another or can be formed integrally together, that is to say connected integrally to one another.In the exemplary embodiment, the structural element 3 is designed as a frame element 10 of the seat system 4, in particular of the backrest 8. The frame element 10 is, for example, the backrest part 9. the vibration damper 2 is thus arranged, for example, on the backrest part 9 designed as a frame element 10 or on a frame element 10 of the backrest part 9. The frame element 10 can be referred to in particular as a backrest frame.As shown by way of example in FIGS. 1 and 2, the seat system 4 in the exemplary embodiment is designed as an integral seat 11 for a belt. The seat system 4 therefore preferably has a seat belt 12 and a belt tensioning device 13. The seat belt 12 and the belt tensioning device 13 are, for example, part of a seat belt system of the seat system 4.The vibration damper 2 has at least one damper mass 14 for damping, in particular specifically damping, at least one vibration or oscillations of the seat system 4, for example the backrest 8, in particular the backrest part 9. As shown by way of example in FIGS. 3, 4 and 5, the damper mass 14 is held at least indirectly, in particular directly, on the structural element 3, in particular the backrest part 9 or the frame element 10, via at least one bearing device 15. The damper mass 14 and the bearing device 15 are preferably formed separately from one another. FIGS. 3 and 4 show the arrangement 1 in each case in a respective lateral schematic partial view according to a respective embodiment. FIG. 5 shows the arrangement 1 in a schematic partial sectional view according to a further embodiment. By damping or attenuating the oscillations by means of the oscillation damper 2, comfort of the motor vehicle can be particularly improved.In order to be able to keep weight and / or production outlay, in particular production costs, of the motor vehicle, in particular of the seat system 4, particularly low, it is provided that the damper mass 14 is formed at least by at least one component 16 of the belt tightening device 13 for the seat belt 12. In other words, at least the component 16 of the belt tightening device 13 is designed as the damper mass 14 or at least as part of the damper mass 14. This means that at least one component 16 of the belt tightening device 13, which is referred to in particular as retractor, is the damper mass 14 of the vibration damper 2, i.e. acts as the damper mass 14. It can be seen that the belt tensioning device 13, which is referred to in particular as a belt retractor, can be used at least partially as an absorber, in particular for absorbing oscillations of the seat contact 4, in particular of the backrest part 9.The component 16 is designed, for example, as a housing element 17 and / or as a belt retractor of the belt tensioning device 13. The damper mass 14 is thus formed, for example, at least by the housing element 17 and / or the belt retractor. For example, it is possible that, if the damper mass 14 is designed as the belt retractor and, in particular, if the damper mass 14 is not designed as the housing element 17, the structural element 3 is the housing element 17. The housing element 17 can be referred to in particular as a housing.In the exemplary embodiment shown in FIG. 3, it is provided that the bearing device 15 has at least one spring element 18, by means of which the damper mass 14 is held at least indirectly, in particular directly, on the structural element 3, in particular on the backrest part 9 or the frame element 10. In particular, the spring element 18 is designed as a damper spring of the vibration damper 2. In particular, because the bearing device 15 has the at least one spring element 18, the bearing device 15 is designed as an elastic suspension for the damper mass 14.In the respective embodiment shown in FIGS. 4 and 5, it is provided that the bearing device 15 is formed at least in regions, in particular predominantly or completely, from an elastic material 19 which is formed in particular separately from the spring element 18 and is, for example, a plastic 20. The plastic 20 is, for example, an elastomer. In the exemplary embodiment shown in FIG. 4, the damper mass 14 is connected at least indirectly, in particular directly, to the structural element 3, in particular the backrest part 9 or the frame element 10, via the bearing device 15 formed from the elastic material 19 by means of a bolt connection 21. In the exemplary embodiment shown in FIG. 5, the damper mass 14 is connected at least indirectly, in particular directly, to the structural element 3, in particular the backrest part 9 or the frame element 10, via the bearing device 15 formed from the elastic material 19 by means of a screw connection 22. The damper mass 14 and the structural element 3 are thus screwed to one another via the bearing device 15. In particular, in the bolt connection 21 or the screw connection 22, the damper mass 14 and the structural element 3 can be moved relative to one another by the elastic material 19. Overall, it can be seen that elastic suspension for the damper mass 14 on the structural element 3 is thus effected by the elastic material 19. In particular, the elastic material 19 or the bearing device 15 formed from the elastic material 19 is designed as an absorber spring of the vibration absorber 2.In a further embodiment, it is provided that the damper mass 14 has at least one first connecting means 23 and at least one second connecting means 24, in particular different from the first connecting means 23, is provided, in particular arranged, on the structural element 3, in particular on the backrest part 9 or the frame element 10. This is schematically depicted in FIG. 2 by way of example, but it is possible for each of the respective embodiments shown in FIGS. 1 to 5 to have the connecting means 23, 24.Preferably, the connecting means 23, 24 are movable relative to each other between at least two positions. In particular, the respective position can be understood to mean a respective position of the damper mass 14 relative to the structural element 3, in particular the backrest part 9 or the frame element 10. Preferably, the connecting means 23, 24 are in a first of the positions 26 in their installation position 25 provided in the motor vehicle. In the first position 26, the damper mass 14 is movable, in particular via the bearing device 15, relative to the structural element 3, in particular the backrest part 9 or the frame element 10. Thus, in the first position 26, the oscillations can be cancelled by means of the oscillation damper 2.It is preferably provided that the connecting means 23, 24 can be moved into the second of the positions as a result of an accident-induced movement of the damper mass 14 relative to the structural element 3. In other words, the connecting means 23, 24 can be moved into the second position as a result of the accident-induced relative movement between the damper mass 14 and the structural element 3. This means that, in the event of the accident-induced movement of the damper mass 14 relative to the structural element 3, in particular as a result of the accident-induced movement, the movement of the connecting means 23, 24, in particular from the first position, into the positions is associated. In the second position, by means of the connecting means 23, 24, the movement of the damper mass 14 relative to the structural element 3 can be prevented or prevented by forming a positive connection, in particular between the damper mass 14 and the structural element 3. As a result, in the event of an accident, uncontrolled movement of the damper mass 14 relative to the structural element 3 can be prevented, as a result of which safety of the motor vehicle can be particularly increased.For example, one of the connecting means 23, 24, in particular the second connecting means 24, is designed as a receiving opening 27 and the other of the connecting means 23, 24, in particular the first connecting means 23, is designed as a receiving element 28, which is designed in particular corresponding to the receiving opening 27 and can be arranged or is arranged in the receiving opening 27 for forming the positive connection, in particular directly.The belt tensioning device 13 is arranged, for example, at least in regions, in particular predominantly or completely, behind the backrest part 9 in the vehicle longitudinal direction 30 of the motor vehicle. For example, the belt tensioning device 13 is at least partially, in particular predominantly or completely, covered by at least one cover element, which is part of the backrest 8, for example, wherein the cover element is formed separately from the backrest part 9, for example. In other words, the belt tensioning device 13 is arranged at least partially, in particular predominantly or completely, within the backrest 8.List of reference characters1 Arrangement 2 Vibration damper 3 Structural element 4 Seat contact 5 Seat part 6 Seat surface 7 Vehicle vertical direction 8 Backrest 9 Backrest part 10 Frame element 11 Belt integral seat 12 Seat belt 13 Belt tensioning device 14 Damper mass 15 Bearing device 16 Component 17 Housing element 18 Spring element 19 Elastic material 20 Plastic 21 Bolt connection 22 Screw connection 23 First connection means 24 Second connection means 25 Installation position 26 First position 27 Receiving opening 28 Receiving element 30 Vehicle longitudinal direction
