Description

[0001] The invention relates to an arrangement comprising a seat with a backrest and a safety belt, wherein at least in the buckled state of the seat, a shoulder belt section of the safety belt is formed and the seat has an adjusting device via which a deflection element guiding the safety belt is arranged on the vehicle seat so as to be displaceable along the backrest.

[0002] As is widely known, a seat belt is a crucial safety feature in vehicles, as it safely restrains vehicle occupants, especially during an accident or sudden braking. A seat belt distributes impact forces evenly across the upper body and pelvis, minimizing the risk of serious injury. Its widespread use has contributed significantly to improving road safety and is required by law in many countries.

[0003] One problem, however, is that the upper exit or attachment point of the seat belt in vehicles is often too high for short people, especially for children in child seats. This leads to an unfavorable belt path on the occupant, particularly in the neck area, which can increase the risk of injury in the event of an accident. With the emerging trend towards robotaxis and the need for child seats integrated into the vehicle seat, the challenge arises of integrating the belt height adjustment and guidance, which is currently found on separate child seats, into the vehicle itself. This is particularly important because children from around the age of 4 use the vehicle's seat belt as a restraint system.

[0004] This transition from separate to integrated seat belts requires not only technological adaptations but also careful consideration of safety standards to ensure the restraint system's protective effectiveness for people of different sizes, such as children of all ages. The seamless integration of these features is critical to improving the protection of short occupants while maintaining comfort and usability.

[0005] Solutions to address this problem are already known from the prior art. For example, AT 13 503 U1 describes a height-adjustable restraint system for securing a passenger to a vehicle seat equipped with a safety belt. The vehicle seat accordingly has a backrest and the fastened safety belt has a shoulder belt running diagonally downwards from a deflection fitting and, connected to this, a lap belt running transversely between a belt buckle and a belt attachment. A slide rail is also attached along a side surface of the backrest or to a load-bearing body part, in which the deflection bracket is mounted on a slide element so that it can be displaced longitudinally along the slide rail. A spring force exerted by an adjusting device on the slide element acts in a direction essentially opposite to gravity to reset the slide element.The sliding element is arranged so that it can move freely along the slide rail, whereby when a force acts on the sliding element transversely to the longitudinal direction of the slide rail and thus in the longitudinal direction of the vehicle, the sliding element is locked in place by locking lugs on the sliding element engaging in locking openings in the slide rail.

[0006] DE 196 18 302 A1 also discloses a height adjustment device with a height-adjustable deflection fitting for forming a shoulder strap of a safety belt, which is coupled to the horizontally displacing seat adjustment of a vehicle seat. The height adjustment device consists of a rail in which a carriage is arranged so as to be longitudinally displaceable. The deflection fitting is attached to the carriage. One end of a Bowden cable is attached to a suspension on the carriage, and the Bowden cable is guided over a deflection pulley arranged at the upper end of the rail. The Bowden cable is then guided towards a seat rail of the seat adjustment of the associated vehicle seat and fastened via a stationary guide to a fastening of a second seat rail.When the vehicle seat is moved along the seat rails, the end of the Bowden cable attached to the second seat rail moves with the seat, resulting in a tension or release movement on the height adjustment slide. This moves the guide fitting and thus the seat belt with the slide up or down.

[0007] A major disadvantage of the above solutions is that the height adjustment is designed in such a way that the deflection fitting is arranged to the side of the backrest. Due to the necessary further deflection of the seat belt, the backrest itself forms an additional, yet undefined deflection point, which makes it impossible to ensure the correct position of the shoulder belt and thus increases the risk of injury to a short occupant. Furthermore, in the event of a load, for example in an accident, the seat belt is shifted significantly to one side of the deflection fitting and thus bunched up in the guide of the deflection fitting. This poses a very high risk of seat belt failure, which can potentially lead to serious injuries to the occupant secured in this way.

[0008] Against this background, the object of the invention is to design an arrangement of the type mentioned at the outset in such a way that the injury potential for an occupant, in particular one with a small body size, is reduced.

[0009] This object is achieved by an arrangement according to the features of patent claim 1. The subclaims relate to particularly expedient developments of the invention.

[0010] According to the invention, an arrangement comprising a seat, preferably a vehicle seat and / or a child seat, with a backrest and a safety belt is provided. In this case, a shoulder belt section of the safety belt is formed at least when the safety belt is fastened. The fastened state is characterized by a locking of the safety belt, in particular a buckle tongue arranged on the safety belt, in a belt buckle of the arrangement assigned to the seat. According to the invention, the seat additionally has an adjusting device or displacement device via which a deflection element and / or guide element guiding the safety belt is arranged on the vehicle seat so as to be displaceable between at least two positions along the backrest.The deflection element is aligned towards a front backrest surface of the backrest facing the seat surface, so that a shoulder belt section attachment facing away from and / or away from the seat surface can be adjusted along the backrest surface via the deflection element on the front of the backrest. By routing the safety belt, and in particular the shoulder belt section, from the top of the seat along the front backrest surface, it is advantageously possible to avoid the backrest itself forming an additional, undefined deflection point. Furthermore, the risk of the safety belt being displaced to a significant extent towards one side of the deflection fitting in the event of a load, for example due to an accident, and thus becoming bunched up in the guide of the deflection fitting is minimized.This minimizes the potential for injury to an occupant, especially one with a short body size, as well as the risk of a seat belt defect. This seat belt guidance is preferably achieved by arranging the deflection element in such a way that an opening guiding and / or passing the seat belt, or the guide of the deflection element, is oriented toward the backrest of the seat.

[0011] The seat and the safety belt are preferably arranged in a motor vehicle, in particular a passenger car. The motor vehicle can, for example, be a self-propelled or autonomous motor vehicle. Furthermore, the seat, in particular the vehicle seat, is preferably designed as an integral belt seat, i.e. as a seat in which the safety belt is at least partially, but preferably completely, integrated. The deflection element can also be connected directly, but preferably indirectly, to a motor drive and designed to be displaceable via this drive. Manual displacement of the deflection element is, however, also possible.

[0012] In principle, it can also be envisaged within the scope of the invention that a single, displaceable deflection element is designed on and / or in the seat, in particular in the backrest.

[0013] In a different, but extremely advantageous development of the invention, the displaceable, preferably second, deflection element is designed separately and / or in addition to a deflection element, in particular a first, which is formed stationary on the backrest, in particular on the upper side and / or in the region of the upper side of the backrest. The separate design advantageously makes it possible to minimize the mass to be displaced, since the displaceable deflection element can have a simplified structural design. This also leads to a structural simplification of the adjusting device and thus a smaller installation space requirement. Furthermore, it is possible to divert and thus distribute a load on the seat belt, in particular one caused by an accident, via an additional connection point into the seat. The displaceable, separate deflection element can be designed, for example, as a belt ring or a belt clasp.

[0014] It is also advantageous if the backrest, in particular a cushion of the backrest, has at least one, in particular gap-like opening and / or at least one recess in which at least part of the displaceable deflecting element and / or at least part of the adjusting device for displacing the deflecting element can be arranged and / or is arranged, in particular during displacement. In this way, the adjusting device and / or the deflecting element can be at least largely integrated into the seat, here specifically the backrest, and / or displaced therein. Furthermore, it is possible to mount the deflecting element via a guide, preferably arranged on the rear of the seat, in particular in a space-saving manner. The deflecting element itself or a holding element holding the deflecting element would be guided through the backrest via the at least one opening. The embodiments also lead to increased safety for an occupant, e.g.from contact with the adjustment device and / or parts of the guide of the deflection element.

[0015] It is also particularly advantageous if, in one embodiment of the invention, a cover device is provided on the deflecting element and / or the backrest, by means of which the at least one opening and / or the at least one recess can be concealed, at least on the backrest side. A recess, particularly a large one, for example for accommodating the adjustment device and / or the displaceable deflecting element, leaves an unsightly impression and could also compromise safety due to the potential access of an occupant to the adjustment device. The implementation of a cover device advantageously offers a solution to avoid these disadvantages.

[0016] In an advantageous development of the invention, the deflection element is furthermore held by a retaining element of the adjustment device that extends at least partially laterally of the backrest, for example, in a guide of the adjustment device. This enables an elegant solution, in particular to avoid gap-like openings in the backrest through which at least part of the deflection element would have to be guided. This ensures a more aesthetically pleasing appearance of the backrest.

[0017] An embodiment of the invention is also considered advantageous if the deflection element is pivotably mounted on and / or in the seat, in particular on and / or in the backrest, via the retaining element. This makes it possible to dispense with a guide, which in particular enables linear displacement of the deflection element, thereby reducing the space requirement for the adjustment device. Only a rotatable or pivotable mounting needs to be provided. The reduced space requirement thus makes it possible, among other things, to incorporate additional components, in particular the adjustment device, in and / or on the seat.

[0018] Furthermore, an embodiment of the invention has the advantage if the adjusting device has a locking mechanism or latching mechanism, via which the deflecting element, in particular via the holding element, can be fixed in at least two positions. In a further development of this, the positions are designed as pivoting positions. The locking mechanism can advantageously prevent undesirable and / or disadvantageous displacement of the deflecting element, especially in the event of an accident-related load on the seat belt, and thus ensure the safety of a passenger in the seat, particularly one of small stature. The locking mechanism can prevent linear displacement and / or pivoting displacement of the deflecting element, wherein the positions in which the deflecting element can be locked can be designed to be continuously adjustable or adjustable in steps.

[0019] An embodiment of the invention is also advantageous if the displaceable deflecting element and / or the holding element are designed such that, in one of the at least two positions, in particular an upper position, no force can be exerted on the deflecting element and / or the holding element via the safety belt. The upper position is preferably designed as an upper pivot position. Additional securing of the displaceable deflecting element in the position in which no force acts on the deflecting element would therefore not be necessary, which could, for example, make the locking mechanism structurally simpler and therefore more cost-effective.

[0020] In a further advantageous embodiment of the invention, the deflecting element and / or the holding element are guided via a slotted guide—the adjustment device—wherein the slotted guide is configured such that a transverse movement can be imposed on the deflecting element and / or the holding element during displacement, particularly during pivoting displacement between the positions. The movement transverse to the backrest of the seat and correspondingly parallel to the backrest, thus in the transverse direction of the vehicle, advantageously provides an optimized belt path, particularly for occupants of short stature, such as children. This is due to the fact that short stature is usually accompanied by a narrow body width.

[0021] In an advantageous embodiment of the invention, at least part of the adjusting device and / or the deflecting element is also designed as a force limiter. A load acting on the occupant, in particular an accident-related load, can thus be limited, thereby minimizing injuries to the occupant caused by the seat belt. Integration into the adjusting device and / or the deflecting element also advantageously minimizes the required installation space compared to a separate design of a force limiter. The force limiter can be designed, for example, as a torsion bar, with the torsion bar forming at least part of the holding element. Furthermore, the force limiter can be designed on its own or in combination with a design as a torsion bar as part of a bearing and / or a guide that accommodates the holding element and / or the deflecting element.

[0022] The invention permits numerous embodiments. To further clarify its basic principle, several of them are shown in the drawing and are described below. The drawing shows in Fig. 1 to 4 show a first embodiment of the arrangement with a single displaceable deflection element; Fig. 5 to 9 show a second embodiment of the arrangement with a separate, linearly displaceable deflection element; Fig. 10 to 13 designs of adjustment devices; Fig. 14, Fig. 15 an embodiment of the arrangement with a linearly displaceable holding element extending at least partially laterally of the backrest; Fig. 16 to 19 show an embodiment of the arrangement with a holding element extending at least partially laterally of the backrest and pivotably arranged on the seat; Fig. 20 to 22 Design forms of a locking mechanism of the adjustment device.

[0023] The Fig. 1 shows an arrangement according to the invention comprising the seat 1 and the safety belt 3, wherein the seat 1 has the backrest 2 with a front backrest 9 (not shown in detail) facing the seat surface of the seat 1. In this embodiment, the seat 1 is an integral belt seat, wherein the deflection element 6 guiding the safety belt 3 is displaceably arranged in the head-end region of the seat 1.

[0024] In particular, the deflection element 6 is located, as in the Fig. 2, in the upper position 7, which is formed at the head-side end of the backrest 2 and thus at a smaller distance therefrom than the lower position 8 of the deflection element 6, which is thus formed at a further distance from the head-side end in the direction of the seat surface of the seat 1 (not shown in detail). The deflection element 6 is in this case by means of the Fig. 3 and Fig. 4 shown adjusting device 5 between the two positions 7, 8, in particular continuously displaceable.

[0025] In addition, the Fig. 1 and Fig. 2 that the deflection element 6 is aligned towards the backrest 9, so that the projection 10 of the shoulder belt section 4 of the safety belt 3, which is formed opposite the deflection element 6 of the seat surface, can also be changed in position between the two positions 7, 8 via the deflection element 6 on the front side of the backrest 2 along the backrest 9 and is changed in position accordingly when the deflection element 6 is moved between the positions 7, 8. This is shown in the Fig. 2 by an arrow P. The displacement and / or change in position corresponds in this case to a height adjustment of the deflection element 6 and / or the attachment 10 on the backrest 2. In this way, the safety belt 3 and in particular the shoulder belt section 4 can be advantageously adapted to the body size of an occupant secured on the seat, wherein the upper position 7 is suitable for adult occupants and the lower position 8 is suitable for occupants of reduced body size, such as children. The shoulder belt section 4 of the safety belt 3 is, as shown in particular in the Fig. 2, at least in the buckled state of the safety belt 3, in which the, for example in the Fig. 1, the belt tongue of the safety belt 3 is locked in a buckle assigned to the seat 1.

[0026] In order to enable the displacement of the deflection element 6, the backrest 2, as shown in the Fig. 3 and Fig. 4, also has the recess 13, in which at least a part of the displaceable deflection element 6 and at least a part of the adjustment device 5 for displacing the deflection element 6 can be arranged and / or is arranged. In particular, in the Fig. In the upper position 7 shown in Figure 4, the deflecting element 6 is only partially arranged in the recess 13, whereas the deflecting element 6 dips into the recess 13 during displacement and is arranged completely in the recess 13 at least in the lower position 8. Furthermore, the deflecting element 6 is mounted, in particular for the purpose of displacement, in the two guides 17, via which a linear displacement of the deflecting element 6 can be realized. The guides 17 themselves are arranged on the backrest 2, specifically the backrest frame 18.

[0027] Since the recess 13 in the backrest 2 does not leave an aesthetically pleasing impression and due to the potentially possible access of an occupant to the adjustment device 5 via the recess 13, the safety of the occupant cannot be guaranteed, as the Fig. 2 to 4, the cover device 14 is designed on the displaceable deflection element 6 and the backrest 2, by means of which the recess 13 on the side of the backrest 9 can be concealed. In this embodiment, the cover device 14 comprises the cover element 19, which is designed in the form of a roller blind. Furthermore, the cover device 14 comprises the winding device 20, here in the form of a winding roller, in which one end of the cover element 19 is secured against a return element, in particular a torsion spring, so that the cover element 19 can be retracted and extended relative to the winding device 20. The winding device 20 is also connected to the deflection element 6, here in particular to the lower region of the deflection element 6 opposite the upholstery part 21 of the backrest 2, and the end of the cover element 19 not secured in the winding device 20 is connected to the backrest 2, here specifically to the upholstery part 21.Thus, when the deflecting element 6 is moved into or out of the winding device 20, the cover element 19 is pulled in or out of the winding device 20 and thus follows the deflecting element 6 in such a way that the recess 13 is always covered. The cover element 19 is essentially flush with the backrest 9.

[0028] From the Fig. 5 to 9 show a further embodiment of the arrangement of the seat 1 and the safety belt 3, wherein the displaceable deflection element 6 in this embodiment is designed separately from the further deflection element 11 fixedly formed on the backrest 2. The displaceable deflection element 6 is designed as a belt clip, in particular a U-shaped belt clip, which, as in the embodiment of Fig. 1 to 4, is again displaceable via the two guides 17 between the upper position 7 and the lower position 8. A part of the deflection element 6 designed as a belt clip, here the longitudinal struts 22 arranged in the guides 17, are arranged, at least when displacing the deflection element 6, in the two slot-shaped openings 12 spaced apart in the backrest 2, in particular in the upholstery part 21, and thus pass through the backrest 2 from the rear of the backrest 2 to the front backrest side 9. To accommodate the guides 17 belonging to the adjustment device 5, the backrest 2 also has the recess 13, wherein the guides 17 are also again arranged on the backrest frame 18. This is particularly evident from the Fig. 5 and Fig. 6 stands out.

[0029] In order to maintain an aesthetically pleasing appearance of the backrest 2 by making the openings 12 largely unobtrusive, the parts of the backrest 2 arranged on either side of the openings 12, here the upholstered part 21, lie against one another at least in sections in a state in which the openings 12 are not loaded by the deflection element 6 and / or parts of the adjustment device 5, e.g. the guides 17. This is shown in detail in the Fig. 7, wherein a portion of the guide 17 is arranged in a section of the illustrated opening 12. However, in the section of the opening 17 extending from the guide 17 to the backrest 9, in which no portion of the guide 17 is located, the two opposing parts of the backrest 2 rest against one another. When the deflection element 6 is displaced, the two parts are then separated or pushed apart.

[0030] In addition, the Fig. 8 the movable deflection element 6 again in the upper position 7, the Fig. 9 also in the lower position 8. From the Fig. 8 further shows that the displaceable deflection element 6 is designed such that in one of the two positions 7, 8, here the upper position 7, no force can be exerted on the displaceable deflection element 6 via the safety belt 3. For this purpose, the upper position 7 is designed so far away from the attachment 10 of the shoulder belt section 4 that the shoulder belt section 4, particularly when the safety belt 3 is fastened, runs below the deflection element 6. Fig. 8 and Fig. 9 also show the stationary deflection element 11, which is arranged at the head-side end of the backrest 2.

[0031] Furthermore, the further Fig. 10 to 13 embodiments of adjusting devices 5, wherein the Fig. 10 and Fig. 11 an adjustment device 5 for motorized and Fig. 12 and Fig. 13 Adjustment devices 5 for manually moving the deflection element 6, which is designed here, for example, as a belt clip.

[0032] The adjustment device 5 of the Fig. 10 and Fig. 11 has two bearing points, via which the deflection element 6 is mounted in the adjustment device 5. One of the bearing points is designed as a guide 17, and the second bearing point as a spindle drive. The spindle drive comprises the motor, in particular electric, drive 23 and the spindle 24. The force absorption or force flow from the deflection element 6 into, for example, the backrest frame 18 shown in the above-mentioned figures takes place via the spindle 24. This enables a continuous displacement of the deflection element 6.

[0033] The adjustment devices 5 of the Fig. 12 and Fig. 13 each have the locking mechanism 16, via which the displaceable deflecting element 6 can be fixed in several positions or locking positions along the adjustment path between the upper position 7 and the lower position 8. For this purpose, the respective deflecting element 6 is mounted on the guide 17 by means of the adjusting element 25 of the adjusting device 5, here a sliding plate, wherein the deflecting element 6 is connected to the adjusting element 25 via the abutment 26 formed on the deflecting element 6, counter to the restoring force of the restoring element 27, here a spring, specifically a compression spring. The locking mechanism 16 also comprises the locking elements 28 and the counter-locking element 29 formed on the end of the deflecting element 6 that does not guide the safety belt 3, which are engaged in the respectively illustrated locking state of the locking mechanism 16, thereby blocking the displacement of the deflecting element 6.The locking state is maintained by the restoring force acting against the adjusting element 25, which also forces the deflecting element 6 into contact with the guide 17. The transfer from the locking state to an unlocking state (not shown in more detail), or unlocking, is carried out by a manual force acting on the deflecting element 6 in the direction of the adjusting element 25, so that the restoring element 27 is compressed and the locking elements 28 and the counter-locking element 29 are disengaged. In the unlocking state, the displacement of the deflecting element 6 is then possible. The direction of force action for the transfer and the options for subsequent displacement are shown in the . Fig. 12 and Fig. 13 indicated by arrows P. The shape of the locking elements 28 and the counter-locking element 29 of the embodiments of the locking mechanism 16 of the Fig. 12 and Fig. 13 are different. The locking elements 28 and the counter-locking element 29 of the locking mechanism 16 of the Fig. 12 are cuboid-shaped, the locking elements 28 and the counter-locking element 29 of the locking mechanism 16 of the Fig. 13 wedge-shaped.

[0034] Furthermore, the Fig. 14 and Fig. 15 discloses an embodiment of the arrangement of seat 1 and safety belt 3, in which the displaceable deflection element 6 is held in the guide 17 mounted on the backrest frame 18 via the holding element 15 of the adjusting device 5, which extends at least partially laterally of the backrest 2. The holding element 15 of the embodiment in the Fig. 14 is straight, the holding element 15 of the version in the Fig. 15 is angled. The angled holding element 15 enables the guide 17 to be arranged on the rear side of the backrest 2, so that it is essentially concealed from the backrest surface 9 and is also less exposed. Both embodiments also offer the advantage that the backrest 2 does not have any recesses, e.g. in the Fig. 5 to 7. This provides both an improved aesthetic appearance and increased safety. The deflection element 6 is designed as a belt clip that circumferentially encloses the safety belt 3 and / or the shoulder belt section 4.

[0035] The further embodiment of the arrangement of seat 1 and safety belt 3 according to the Fig. 16 to 19 has a displaceable deflection element 6 which is designed separately from the stationary deflection element 11 and which is held by the holding element 15 of the adjustment device 5 which extends at least partially laterally of the backrest 2. In this case, the displaceable deflection element 6 is arranged pivotably on the seat 1 via the holding element 15 which is designed in the form of a belt crank, so that the deflection element 6 can be moved between the position 7 which is designed as the upper pivot position and which is in the Fig. 16 and Fig. 17, and the lower pivot position 8, which is shown in the Fig. 18 and Fig. 19. The movement between the upper position 7 and the lower position 7 is shown in the Fig. 16 and Fig. 17 indicated by an arrow P.

[0036] From the Fig. 20 to 22 also show designs of a locking mechanism 16 of the adjusting device 5, via which in particular the Fig. 16 to 19, which is held by the pivotable holding element 15, can be fixed in the two positions 7, 8 designed as pivot positions. The holding element 15 is rotatably mounted via the bearing 30, in this case a pivot bearing, so that it can be displaced between the positions 7, 8. The locking mechanism 16 also comprises the locking element 28 and the counter-locking element 29 arranged at the end of the holding element 15 not connected to the deflection element 6, which counter-locking element 29 is arranged in the Fig. 20, the locking mechanism 16 is in engagement with one another. The locking element 28 and the counter-locking element 29 have a complementary design, by means of which the holding element 15 and thus the displaceable deflecting element 6 are arranged in a rotationally fixed manner in the locking state, e.g., on the backrest frame 18, and thereby a pivoting movement of the holding element 15 and thus of the deflecting element 6 is prevented. Furthermore, the holding element 15 and thus the counter-locking element 29 are mounted in the bearing 30 for linear movement against the restoring force of the restoring element 27, here a spring element, specifically a compression spring, which is supported on the abutment 26 and the counter-locking element 29, wherein the bearing 30 in this design also forms the abutment 26.By applying a force from the counter-locking element 29 to the abutment 26, the locking element 28 and the counter-locking element 29 can be disengaged, whereby the locking mechanism 16 can be transferred into an unlocked state (not shown in detail). In this unlocked state, the holding element 15 is freely rotatable, and the deflecting element 6 can thus be displaced by pivoting. The direction of the force for the transfer as well as the options for subsequent displacement are shown in the . Fig. 20 indicated by arrows P.

[0037] From the Fig. 21 and Fig. 22 also shows complementary designs of the locking element 28 and the counter-locking element 29. The Fig. 21 shows a square shape of the locking element 28 and the counter-locking element 29, ie in particular a rectangular and especially a square cross-section. Fig. 22, however, shows a cylindrical shape of the locking element 28 and the counter-locking element 29, ie in particular a circular cross-section, wherein the counter-locking element 29 has a locking lug 31 on its outer circumference and the locking element 28 has two locking grooves 32 on its inner circumference spaced apart from one another in the circumferential direction, which engage with the two in the Fig. 16 to 19, which are designed as pivoting positions.
