Description

[0001] The present invention relates to a belt retractor having the features of the preamble of claim 1 and to a vehicle seat having the features of the preamble of claim 7.

[0002] Restraint systems for motor vehicles include not only airbags but also seat belt systems, which directly restrain the occupant via a seat belt. The seat belt system can, for example, be designed as a three-point belt. In this case, one end of the seat belt can be wound onto a belt shaft of a belt retractor, which can be locked in the extension direction, and the other end is fixed to the vehicle via an end fitting. Furthermore, the seat belt has a tongue that can be locked into a buckle permanently attached to the vehicle. In the locked position, this tongue divides the seat belt webbing into a diagonal section that crosses the occupant's chest and a lap section that crosses the occupant's pelvis.If the safety belt system is designed as a 2-point belt or as a 4-point belt, the free ends can instead be locked directly via a belt tongue in a vehicle-mounted belt buckle.

[0003] The restraining forces required in an accident are then transferred from the seat belt to the vehicle structure via the fixed attachment points, i.e., the belt retractor, the end fitting, and / or the buckle. Therefore, these components themselves and their attachment to the vehicle structure must be designed to bear the load. Furthermore, it may be necessary for the seat belt to be redirected again from the belt retractor shaft to ensure it is positioned at an angle that is favorable for restraining the occupant. The same problem arises if, due to space constraints, the belt retractor must be mounted in a specific location, and the seat belt must first travel a longer path before being redirected and positioned over the occupant.

[0004] From this perspective, seat-integrated seat belt systems, such as those found in convertible seats, swivel seats, or bench seats, present a particular problem. The issue with such seat-integrated seat belt systems is the very limited installation space available within the vehicle seat. Furthermore, the restraint forces from the belt retractor must be transferred to the vehicle seat, requiring correspondingly rigid attachment points on the seat, which complicates the mechanical attachment of the belt retractor. This is especially true for vehicle seats that lack a steel frame or for seats designed as benches, i.e., for example, two or three seats side by side.

[0005] From DE 10 2021 105 010 B4 a load-bearing belt winder with two housing halves is known, which are in contact at two contact lines above and below functional modules.

[0006] Furthermore, a load-bearing structural part of a vehicle seat is known from DE 10 2018 213 279 A1, which has a cavity in which a belt retractor is arranged.

[0007] DE 10 2019 205 307 A1 discloses a belt retractor for attachment to a vehicle seat, which has a load-bearing frame with a belt shaft mounted therein, wherein the frame is shape-individualized and has a fastening attachment for a load-bearing connection with a vehicle structure.

[0008] DE 20 2010 008 379 U1 discloses a bench seat for vehicles, wherein a seat belt retractor can be fixed to the support frame.

[0009] Furthermore, a hinge end fitting for attaching a safety belt to a reversible seat is known from DE 10 2005 061 541 B4.

[0010] Against this background, the invention is based on the objective of providing a belt retractor for a vehicle seat and a vehicle seat with such a belt retractor, which enable simple integration of the belt retractor into a vehicle seat.

[0011] To solve the problem, a seatbelt retractor with the features of claim 1 and a vehicle seat with the features of claim 7 are proposed. Further preferred embodiments and developments can be found in the dependent claims, the figures, and the accompanying description.

[0012] To solve the problem, a belt retractor for mounting in and / or on the backrest of a vehicle seat is proposed. The belt retractor has a housing in which a belt shaft is rotatably mounted about a pivot axis, onto which a seat belt of the belt retractor can be wound. The seat belt exits the belt retractor through an opening, and the housing of the belt retractor has at least two mounting points for attachment in and / or on the backrest of a vehicle seat. It is proposed that the housing has at least two housing parts, which are connected to each other by means of at least two connecting elements, preferably four connecting elements. The at least two connecting elements form at least two mounting points for attachment in and / or on the backrest of a vehicle seat.

[0013] The connecting elements allow for the simple creation of a mounting point on the seatbelt retractor, enabling easy assembly and efficient force transmission from the mounting point to the housing, particularly to at least two housing parts, of the seatbelt retractor. The housing and housing parts are preferably made of metal or a metal alloy. Furthermore, the housing parts are preferably sheet metal. The housing preferably consists of two shell- and / or cover-like housing parts, which are connected to each other by the connecting elements. The connecting elements simultaneously provide mounting points for attachment to a vehicle seat. Preferably, the seatbelt retractor can be secured to and / or in a vehicle seat using simple screws via the connecting elements.Due to the design of the mounting points with connecting elements, the mechanical requirements for the vehicle seat to accommodate the seatbelt retractor are reduced, and the possibilities for positioning the seatbelt retractor on a vehicle seat are expanded. Preferably, the two housing parts and the connecting elements form an integral assembly, making the seatbelt retractor transportable and ready for immediate installation on a vehicle seat.

[0014] According to the invention, the connecting elements are designed as rivet nuts. The rivet nuts can be inserted, for example, from one side during assembly and simultaneous joining of the housing parts. In advantageous embodiments, the rivet nuts have a preferably hexagonal rim, which, during assembly, is brought to rest against a housing part, for example, in a hexagonal opening. In alternative embodiments, the rivet nuts can also be inserted into round openings in the housing. Subsequently, the rivet nut is preferably deformed on the side opposite the rim by pulling on a screw that engages in the thread of the rivet nut, so that the housing parts are permanently fixed by the rivet nut between the rim and a bead formed by the deformation. The thread of the rivet nut is then available for mounting the belt retractor.Preferably, the connecting elements, each designed as a rivet nut, are formed in one piece. The rivet nuts preferably have a bead that is larger than the head of the respective rivet nut.

[0015] The mounting in and / or on a backrest refers to the orientation and position of the belt retractor housing. For example, when mounted on and in a backrest, the belt retractor's mounting points can be located on the back of the backrest. When mounted inside a backrest, the belt retractor housing projects into the backrest from the mounting points, while when mounted on a backrest, the belt retractor housing projects out of the backrest from the mounting points. The proposed belt retractor therefore offers a wide variety of mounting options in this respect as well. The mounting points are preferably located in mounting sections of the housing or in the mounting sections of one or both housing parts.

[0016] It is particularly advantageous if a fastening point and / or a rivet nut is positioned centrally below the belt shaft and the seat belt. This largely avoids the introduction of additional moments under load, and the forces from the seat belt can be efficiently transferred into the seat structure.

[0017] In an advantageous embodiment, the housing has at least two housing parts which are connected by means of at least one clinch joint.

[0018] A clinch joint, also known as a clinch connection, is particularly suitable for the additional joining of two sheet metal housing parts. This can, for example, further increase the rigidity and strength of the housing. The belt retractor preferably features several clinch joints. Furthermore, the at least one additional clinch joint allows for a particularly flexible positioning of the rivet nuts as fastening points on the belt retractor housing, enabling a highly adaptable connection. Alternatively or additionally to the clinch joint, other mechanical connections, such as adhesive bonding, are also possible.

[0019] It is further proposed that the housing comprises two housing parts which are connected to each other by means of at least one folded joint. The folded joint can, for example, extend over the entire length of the edges at the top and / or bottom edge, particularly over the mounting sections. In other embodiments, it is also possible that the folded joint extends only over a short section, e.g., a partial section of the edges, particularly the mounting sections.

[0020] In further advantageous embodiments, the housing has at least two housing parts which are connected by means of at least one clinch connection and one fold connection, thereby achieving a particularly stable and secure mechanical connection.

[0021] Preferably, the belt retractor comprises a belt guide element which is inserted into a housing part of the housing and has the exit opening for the seat belt.

[0022] The belt guide element preferably closes the housing of the belt retractor to such an extent that only the exit opening for the seat belt remains. The belt guide element particularly prevents dirt from entering the belt retractor. The exit opening is preferably tunnel-shaped and further preferably has a flat, rectangular cross-sectional area. The exit opening is also preferably tubular, which further hinders the ingress of foreign objects and dirt. The belt guide element can be made of plastic, preferably by injection molding.

[0023] In advantageous embodiments, the belt guide element is inserted transversely to the exit direction of the safety belt into a housing part.

[0024] This allows for easy installation and prevents the belt guide element from coming loose or being pulled along in the event of unwanted contact between the seat belt and the belt guide element.

[0025] According to a further development, it is proposed that at least three fastening points lie in a common fastening plane of the belt retractor.

[0026] The common mounting plane facilitates the structural connection and installation of the seatbelt retractor to the backrest of a single vehicle seat, a backrest of a vehicle seat for two or three people, or a vehicle bench seat for several people. Furthermore, the structural connection, installation, and fastening of the seatbelt retractor to such a backrest are also simplified. The housing of the seatbelt retractor can extend forward from the mounting plane or from the edges or mounting sections of at least two housing parts, which are preferably connected to each other by the connecting elements, in particular the rivet nuts, either towards an occupant in a vehicle seat or backward away from an occupant in a vehicle seat.

[0027] It is further proposed that the exit opening for the seat belt be positioned parallel to the mounting plane. This ensures good force transmission from the seat belt to the vehicle seat.

[0028] Furthermore, to solve the problem, a vehicle seat with the features of claim 7 is proposed. A vehicle seat with a seat belt retractor according to any one of claims 1 to 6 is proposed, wherein the vehicle seat has a backrest, and the seat belt retractor is attached in and / or to the backrest.

[0029] A suitable vehicle seat allows for integration into the seat backrest, whereby the integration of the seat belt retractor is not limited to attachment to a seat pillar or as an integral upper cross member of the vehicle seat. Rather, the seat belt retractor can be mounted or attached to the backrest in a largely flexible manner at various positions. Therefore, in possible embodiments, the seat belt retractor can be placed on the backrest at different locations and, for example, covered. In alternative embodiments, the seat belt retractor can be integrated into the backrest at various points, so that the backrest forms a closed surface behind which the seat belt retractor is recessed. The vehicle seat preferably has corresponding mounting positions for the connecting elements, in particular for the connecting elements designed as rivet nuts.

[0030] Preferably, the exit opening of the seatbelt retractor is directed upwards. "Upwards" here refers to the orientation of the vehicle seat within the vehicle, so that the exit opening preferably points towards the upper end of the backrest. This allows for easy belt guidance from the belt shaft without deflection, thus enabling simple force transmission parallel to the backrest and preferably parallel to a mounting plane. The upward-facing exit opening is particularly advantageous in combination with the belt guide element, as it effectively prevents particles from falling into the seatbelt retractor.

[0031] According to an advantageous further development, it is proposed that the vehicle seat has a belt guide, wherein the seat belt is guided from the belt retractor to the belt guide parallel to the backrest. The belt guide in the vehicle seat is preferably attached to and / or in the backrest separately from the belt retractor. By separating the belt guide, for example for feeding the seat belt to the front, and the belt retractor, the largely free positioning of the housing, for example by means of the connecting elements, in particular the connecting elements designed as rivet nuts, as fastening points, can be particularly well utilized. Accordingly, a space-optimized integration of one or more belt retractors into a backrest can be achieved. The belt guide can, for example, be a ring on the vehicle seat, in particular on the seat pillar, or an exit plate for the seat belt.

[0032] In preferred embodiments, the belt retractor and the belt guide are spaced more than 10 cm apart. Accordingly, with a typical belt guide featuring a belt retractor integrated into the backrest, it is not necessary to attach the belt retractor to the upper end of the backrest. Therefore, the belt retractor can be mounted in a lower area of ​​the backrest, allowing for a flatter backrest in the upper section.

[0033] According to a further development, it is proposed that the seat belt be guided from the belt shaft out of the belt retractor without contact. Accordingly, preferably no deflection takes place within the belt retractor, so that the seat belt can be guided out of the retractor without additional friction caused by a deflection. Furthermore, the seat belt is preferably guided out of the exit opening without contact, so that additional friction is also avoided at this point.

[0034] In preferred embodiments, the belt retractor and the belt guide are spaced more than 10 cm apart. Accordingly, with a typical belt guide featuring a belt retractor integrated into the backrest, it is not necessary to attach the belt retractor to the upper end of the backrest. Therefore, the belt retractor can be mounted in a lower area of ​​the backrest, allowing for a flatter backrest in the upper area.

[0035] It is further proposed that the belt retractor in the chest area be located in and / or on the backrest, or that the belt retractor in the pelvic area be located in and / or on the backrest. This allows for a functional separation of the belt retractor and the guide, which increases the design possibilities of the vehicle seat and reduces the mechanical requirements for the backrest's fastening elements in relation to the belt retractor's mounting points.

[0036] In an advantageous embodiment, it is proposed that three seatbelt retractors be arranged side by side on a backrest for three occupants. This allows for the simple implementation of an integrated seatbelt retractor in the backrest of a multi-seat vehicle bench.

[0037] According to an advantageous embodiment, it is proposed that the housing extends at least half the width of the backrest of the vehicle seat.

[0038] The invention is explained below with reference to preferred embodiments and the accompanying figures.

[0039] Fig. Figure 1 shows an advantageous embodiment of a seatbelt retractor 10 in a front view. The seatbelt retractor 10 has a seatbelt shaft 12 (shown schematically) rotatably mounted about a pivot axis 25, which is arranged in a housing 11 together with the other functional modules 35 of the seatbelt retractor 10, such as locking elements, seatbelt tensioners, etc. The housing 11 has two housing parts 16, 17, wherein in the illustration the Fig. 1 The front housing part 16, which is shell-shaped, can be seen. The rear housing part 17 is shown in the rear view of the belt retractor 10. Fig. 2 is shown and designed as a lid. The front housing part 16 has an overlapping mounting section 22 at the top and bottom with the rear housing part 17, which is connected by four connecting elements 18. In addition to mechanically connecting the two housing parts 16, 17, the connecting elements 18 also serve as fastening points 15 for attaching the belt retractor 10 to a vehicle seat 40, see also Fig. 5 to 10.

[0040] As in the Fig. As can be seen in Figure 2, the connecting elements 18 are arranged in a common mounting plane 21. This allows the connecting elements 18 or the mounting attachments 15 to be mounted particularly advantageously on flat areas of a vehicle seat 40.

[0041] A safety belt 13 is arranged on the belt spool 12 and is led out of the belt retractor 10 in an exit direction 20. In this advantageous embodiment, the safety belt 13 is guided by a plastic belt guide element 19, which has an exit opening 14 through which the safety belt 13 is led out of the belt retractor 10.

[0042] In the Fig. Figure 3 shows an exploded view of the housing 11 with the two housing parts 16 and 17. Four connecting elements 18 are also shown, which are advantageously designed as rivet nuts, which can be inserted from the rear of the belt winder 10 from the side of the housing part 17 into the mounting sections 22 or edges of the housing parts 16, 17.

[0043] As shown in the exploded view of the Fig. As can be seen in Figure 3, the two housing parts 16, 17 form a cuboid interior space 28 that extends along the axis of rotation 25. The interior space 28 is formed by the interior sections 24 of the two housing parts 16, 17. In the area of ​​the belt shaft 12, onto which the safety belt 13 can be wound into a belt reel 26, the interior sections 24 of both housing parts 16, 17 have partially cylindrical protrusions 27, which are adapted to the cylindrical shape of the belt reel 26.

[0044] Furthermore, in this advantageous embodiment, the housing 11 comprises three bearing plates 29, 30, 31, wherein two bearing plates 29, 30 are arranged on both sides of the belt winder 26 and close off a belt winding chamber 32 axially on both sides along the axis of rotation 25 of the belt shaft 12. The bearing plate 30 divides the interior 28 of the belt winder 10 into a belt winding chamber 32 and a functional chamber 33, in which, for example, a belt tensioner and / or other functional modules 35 that can act on the belt shaft 12 can be arranged. The functional chamber 33 is axially closed off by the bearing plate 31.

[0045] Fig. Figure 4 shows an exploded view with a housing 11, in which the two housing parts 16, 17 are joined by four connecting elements 18 designed as rivet nuts, and a belt guide element 19. As in the Fig. As can be seen in Figure 4, the belt guide element 19 has lateral guides 23 on both sides, with which the belt guide element 19 can be inserted into the housing 11 perpendicular to the exit direction 20 in this advantageous embodiment. The belt guide element 19 includes the exit opening 14, through which the safety belt 13 is guided in the installed state.

[0046] In possible embodiments, the two housing parts 16, 17 are connected, in addition to the connection by the connecting elements 18, which are preferably designed as rivet nuts, for example by push-fit connections or clinch connections, which are preferably also arranged in the overlapping assembly section 22 of the two housing parts 16, 17.

[0047] The Fig. 5 and Fig. Figure 6 shows sectional views through the housing 11 with the two housing parts 16, 17, which are connected in the cutouts by means of a connecting element 18 in the form of a rivet nut. The connecting element 18 has a collar 37 which rests against the housing part 17. The connecting element 18, in the form of a rivet nut, is inserted from the side of the housing part 17 into the openings 39 of the housing parts 16, 17, so that the collar 37 rests against the housing 11. In this case, the collar 37 also serves as a spacer, which prevents the housing 11 from resting completely against the backrest 41 or the vehicle seat 40, thus reducing potential noises, such as squeaking, caused by relative movements under load. The openings 39 of the housing parts 16, 17 for the connecting elements are preferably hexagonal, so that a connecting element 18 with a hexagonal section can be inserted in a rotationally secure manner.A plastic forming process during assembly creates the bead 38, which permanently secures the housing parts 16, 17 between the bead 38 and the collar 37. The connecting element 18, designed as a rivet nut, has an internal thread as a fastening lug 15 into which it is inserted. Fig. 6 a screw 36 is inserted, which can be used, for example, for fastening to a vehicle seat 40.

[0048] In the Fig. Figures 7 to 12 show exemplary embodiments of vehicle seats 40, each comprising belt retractors 10 proposed on the backrest 41.

[0049] Fig. Figure 7 shows, for example, an embodiment of a vehicle seat 40 with a belt retractor 10, which is attached to the backrest 41 by means of the connecting elements 18. The belt retractor 10 is mounted on the backrest 41 at approximately chest height of an occupant. Thus, in this embodiment, the belt retractor 10 is not mounted at the upper end of the backrest 41. The seat belt 13, which exits upwards from the exit opening 14 of the belt retractor 10 towards the headrest 43, runs parallel to the backrest 41 to a belt guide 42, which is located in the upper region of the backrest 41. The belt guide 42 therefore directs the seat belt 13 to the front part of the backrest 41, so that the seat belt 13 can be fastened by an occupant. The seat belt 13 can, for example, be covered by an additional cover.

[0050] Fig. Figure 8 shows a further embodiment of a vehicle seat 40, in which, unlike the embodiment of the Fig. 7 The belt retractor 10 is arranged in the lower area of ​​the backrest 41 at the level of the occupant's pelvis. In this embodiment, the distance between the belt retractor 10 and the belt guide 42 is significantly increased, so that the safety belt 13 is guided parallel to the backrest 41 over a longer section of, for example, more than 40 cm.

[0051] Fig. Figure 9 shows a further advantageous embodiment of a vehicle seat 40 with a belt retractor 10. The belt retractor 10 differs from the embodiments of the Fig. 7 and Fig. 8 is attached in a different orientation in the vehicle seat 40, so that the housing 11 of the belt retractor 10 extends from the attachment points 15 into the backrest 31.

[0052] Fig. Figure 10 shows an advantageous embodiment of a vehicle seat 40 with three seats side by side on a common bench seat. Analogous to the embodiment of the Fig. 7 Three belt retractors 10 are mounted side by side on the backrest 41 in the upper area of ​​the backrest 41, approximately at chest height of an occupant. Accordingly, the three safety belts 13 are guided to three belt guides 42 of the backrest 41.

[0053] Fig. Figure 11 shows a further embodiment of a vehicle seat 40 with three seats side by side on a common bench seat with a common backrest 41. In contrast to the embodiment of the Fig. The belt retractors 10 are each arranged at a greater distance from the belt guides 42 on the vehicle seat 40. Accordingly, the exemplary embodiment of Fig. 11 analogous to the exemplary embodiment of the Fig. 8 with only one seat on the vehicle seat 40.

[0054] Another possible embodiment of a vehicle seat 40 is in the Fig. 12 shown, which differs from the embodiment of the Fig. 9 has three seats arranged side by side for occupants, each with three belt retractors 10 arranged on the backrest 41.
