[0001] manual
[0002] The present invention relates to a deflector for guiding a seat belt in a vehicle, comprising at least a metal body and a mating member made of plastic connected to the metal body, the metal body having a fixed opening for mounting on the vehicle and having a seat belt slot, the metal body having a receiving portion and forming an engagement section on the mating member corresponding to the receiving portion, such that the engagement section engages into the receiving portion, wherein the receiving portion has an inner surface facing the engagement section and the engagement section has an engagement surface facing the receiving portion.
[0003] Typically, this type of deflector is used in a vehicle to guide the seatbelt and hold it in at least three positions within the vehicle. The seatbelt is positioned around the body of the vehicle occupant so that the occupant's body is restrained by the seatbelt during vehicle braking or other movement relative to the vehicle. Here, the seatbelt is tensioned and held in predetermined positions by the deflector, thereby restraining the body in multiple different areas while in a close-fitting state.
[0004] Here, this type of deflector is fixed to the vehicle and provides a seatbelt guide slot to guide the seatbelt, which completely surrounds or at least prevents the seatbelt from being lost. The seatbelt moves along the seatbelt guide slot, for example, when worn by a vehicle occupant or during braking, causing friction between the seatbelt and the deflector, particularly in the area of the seatbelt slot. To provide sufficient restraint, the deflector must not fail within the expected force range. For this reason, a metal body is typically used, having at least one fixed opening for mounting on the vehicle and simultaneously providing the seatbelt slot. To reduce weight and for aesthetic reasons, the deflector typically has a plastic adapter that connects to the metal body. In the manufacture of the metal body, higher tolerances are imposed by manufacturing processes compared to those in the plastic adapter. Therefore, the metal parts are not always manufactured with a precise fit, which can lead to defects when assembled into the deflector and may cause rattling noises between the adapter and the metal body during deflector operation.
[0005] A deflector having the above-described features is known, for example, from DE 10 2004 050 154 B3. Here, the mating section of the fitting engages into the seatbelt groove of the metal body, thereby forming a form-fit connection between the metal body and the fitting in this area. The deflector is fixed to the vehicle via a fixed opening. To prevent rattling noise caused by the deflector stopping on the vehicle, the fitting has at least one integrally formed spring arm on the rear side facing the vehicle, which abuts against the vehicle support, so that vibrations generated during operation do not cause rattling noise.
[0006] However, a disadvantage of deflectors formed in two parts—a metal body and a mating component—is the presence of rattling noises between the mating component and the metal body when the seatbelt slides against the seatbelt guide groove or due to vibrations during vehicle operation. This rattling noises are particularly noticeable in areas forming a form-fit connection, such as through the mating section engaged in the metal body. Furthermore, during the manufacturing of the mating component or the metal body, mating surfaces may not perfectly match each other due to manufacturing reasons. This is especially true for metal stampings, where the metal body is often bent, rolled, or additionally stamped during further processing. The metal body is often manufactured with high tolerance limits. Therefore, the mating component and the metal body (in areas where a form fit should be formed) are often undesirably close to each other, and rattling noises occur particularly between the two components.
[0007] The object of the present invention is to eliminate the disadvantages described in the prior art and to provide an improved deflector for guiding seat belts in a vehicle.
[0008] This objective is achieved by a deflector having the features of the independent claim. Advantageous improvements to the deflector are given in the dependent claims and the specification, wherein the features of the advantageous improvements can be combined with each other in a technically reasonable manner.
[0009] The objective is achieved in particular by a deflector having the features described at the beginning, wherein the engagement section has at least one spring element abutting against the inner surface of the receiving portion.
[0010] For installation in a vehicle, the deflector is secured to the vehicle using a fixing device that can be inserted into a fixing opening in the metal body. Furthermore, a seatbelt can be arranged in a seatbelt slot, thus retaining the seatbelt within the seatbelt slot. In the pre-assembled state, the mating section of the mating component engages with the receiving portion of the metal body, such that the two components are form-fitted together to form the deflector. Moreover, the receiving portion of the metal body has an inner surface that mimics the contour of the mating section of the mating component. The mating surface of the mating section is thus arranged in the receiving portion and can abut against the inner surface of the receiving portion. Preferably, the mating surface at least partially, and most preferably completely, abuts against the inner surface of the receiving portion. This achieves a form-fitting connection between the metal body and the mating component. Here, another connection can be formed between the metal body and the mating component, particularly by also securing the deflector to the vehicle.
[0011] According to the invention, the mating section has at least one spring element that rests against the inner surface of the receiving portion. Here, the at least one spring element is preferably in a tensioned state and pressed against the inner surface of the receiving portion. Therefore, a preload is applied from the mating member to the metal body in the region of the receiving portion by the at least one spring element. In this way, for example, surface defects caused by manufacturing can be compensated by the at least one spring element in the region of the inner surface of the receiving portion, wherein the at least one spring element also rests against the inner surface of the receiving portion even when there is a gap between the metal body and the mating member. Therefore, the spring element helps to compensate for manufacturing tolerances on the metal body caused by manufacturing.
[0012] Furthermore, the presence of at least one spring element abutting against the inner surface of the receiving portion prevents uncontrolled movement between the metal body and the mating member. Thus, the at least one spring element prevents, in particular, the stopping of the inner surface of the receiving portion and the mating surface. Additionally, the at least one spring element advantageously prevents defects in the area of the receiving portion during assembly into the deflector. If relative movement between the two components of the deflector occurs due to vibrations during operation or due to slippage of the seatbelt in the seatbelt groove in the area of the receiving portion, the at least one abutting spring element further prevents rattling or damped excitation of vibrations. The at least one spring element also prevents rattling in other contact areas between the metal body and the mating member.
[0013] The deflector is specifically a two-piece component formed by a metal body and a mating part. The metal body is preferably a metal stamping. This metal stamping is advantageously manufactured at low cost and can advantageously absorb the main part of the force under load without failure.
[0014] The mating part is preferably a plastic part designed as a one-piece construction. Furthermore, the mating part has an engagement section, particularly designed as a protrusion, such that the engagement section engages in a receiving portion constructed onto the metal body. The mating part is preferably designed to be constructed in other areas corresponding to the metal stamping part. Additionally, further connecting parts, such as hooks, are provided for securing the mating part to the metal stamping part, thereby forming the deflector as a pre-assembled self-contained component.
[0015] Here, the mating component may specifically have a lower section and an upper section, wherein a seatbelt guide section may be formed in the area of the seatbelt groove in the metal body on the upper section, thereby guiding the seatbelt by the mating component. Specifically, the mating component may mimic an area or the entire area of the seatbelt groove. The lower section of the mating component is preferably connected to the upper section via two connecting arms, such that the lower and upper sections are connected, and the mating component is designed as a one-piece plastic part. The lower section of the mating component particularly has an engaging protrusion.
[0016] Furthermore, the mating component may have an additional finish profile, making the metal body of the deflector invisible when assembled in the vehicle. When the deflector is assembled in the vehicle, preferably the upper section is at least partially embedded in the fixing opening of the metal body, wherein the fixing device for mounting the deflector on the vehicle preferably passes through the mating component and abuts against it.
[0017] At least one spring element abutting the inner surface of the receiving portion may be, for example, an elastic segment of the engagement section, which protrudes from or bulges from the engagement section or engagement surface, particularly in the unassembled state of the deflector. The spring element is preferably made of the same material as the mating member. Particularly preferably, the at least one spring element is also made of plastic and possesses a degree of flexibility. Furthermore, the at least one spring element may be molded, mounted, or placed on the engagement section such that the at least one spring element presses against the mating member in the pre-assembled state of the deflector. In this way, the at least one spring element prevents rattling noises in the deflector, compensates for manufacturing errors, and avoids defects during assembly into the deflector, particularly by connecting the metal body to the mating member.
[0018] In one embodiment, the at least one spring element provides a spring force acting on the inner surface of the receiving portion. The spring force depends particularly on the deflection of the at least one spring element and the material properties of the mating parts. When in contact with the inner surface of the receiving portion, the at least one spring element is preferably located in the elastic region. The desired preload can be advantageously adjusted according to the spring force, thereby particularly preventing rattling. Preferably, the spring force increases as the at least one spring element deflects away from the inner surface of the receiving portion, thereby preventing the inner surface of the receiving portion from uncontrollably stopping against the mating surface. If the excitation of the deflector causes the metal body and the mating parts to move apart in the region of the receiving portion, the deflection of the at least one spring element toward the inner surface of the receiving portion advantageously prevents uncontrolled loss of the preload.
[0019] In another advantageous embodiment of the invention, the at least one spring element is integrally formed with the mating member. The at least one spring element may be formed, for example, by a protrusion on the mating member itself. Here, the at least one spring element is flexible and protrudes from the mating member in the unassembled state of the deflector. Additional assembly or manufacturing steps can be advantageously omitted when manufacturing the mating member or assembling the deflector. Furthermore, the position of the at least one spring element on the engagement section can be advantageously preset.
[0020] In another advantageous embodiment of the invention, the mating member has at least two spring elements staggered along the seatbelt groove, such that the mating member can provide spring force to the inner surface of the receiving portion at at least two staggered locations. The particularly elongated seatbelt groove, shaped to match the seatbelt, is oriented parallel to the preferably equally elongated receiving portion of the mating member. The mating member with at least two spring elements advantageously prevents unilateral loading or relative movement between the mating member and the metal body. Furthermore, rattling is better prevented in the region of the receiving portion, locally limited manufacturing errors are compensated for by the at least two spring elements, and a higher overall tolerance limit is determined. The staggered arrangement of the at least two spring elements makes it advantageously possible to prevent rattling and compensate for manufacturing errors in different regions of the receiving portion of the metal body.
[0021] In another advantageous embodiment of the invention, the mating surface is arranged such that it has at least one opening, and the at least one spring element is at least partially arranged in said opening. Preferably, the mating surface has one opening for each spring element. The arrangement of the at least one spring element in the at least one opening is advantageously such that the at least one spring element does not protrude when it abuts against the inner surface of the receiving portion of the mating surface, but rather aligns with the mating surface in the region of the opening by means of the area abutting against the inner surface of the receiving portion. In this way, it is advantageously possible to achieve that the inner surface of the receiving portion abuts against the mating surface, wherein a spring force acting on the inner surface of the receiving portion is simultaneously provided by the at least one spring element.
[0022] In another advantageous embodiment of the invention, the at least one spring element is configured such that it is deflectable toward the inner surface of the receiving portion and toward the at least one opening. At least one spring element abutting against the inner surface of the receiving portion can advantageously move within the opening. In this way, the at least one spring element can particularly effectively prevent rattling or compensate for unevenness of the inner surface of the receiving portion due to manufacturing errors. For example, in the case of two or more spring elements each arranged in an opening, contact between the inner surface of the receiving portion and the mating surface may occur in different areas, causing one spring element to deflect, while in another area another spring element deflects and protrudes beyond the mating surface, preventing the mating surface from contacting the inner surface of the receiving portion. Therefore, at least one deflectable spring element can cause at least one spring element to flexibly and advantageously abut against the inner surface of the receiving portion of the metal body.
[0023] In another advantageous embodiment, the surface of the metal body facing away from the inner surface of the receiving portion forms a seatbelt support surface defining the seatbelt groove. In this way, the seatbelt can be guided by the particularly stable metal body. Furthermore, the guidance of at least one spring element, particularly arranged on the opposite side of the seatbelt support surface, advantageously prevents noise near the origin of any rattling sound caused specifically by the sliding of the seatbelt in the seatbelt groove. Therefore, vibrations excited by sliding can be damped particularly effectively and efficiently by at least one spring element.
[0024] In another advantageous improvement, at least two engagement ribs are formed through the engagement surface, wherein the at least two engagement ribs mimic the contour of the inner surface of the receptacle, thereby abutting against the inner surface of the receptacle. The at least two engagement ribs are preferably distributed on the engagement surface, particularly arranged regularly. The at least two engagement ribs are preferably not directly arranged in the region of at least one spring element, but staggered along the seatbelt groove. In this way, lateral movement of the metal body relative to the mating member can be advantageously prevented, wherein at least one spring element laterally abuts against one of the at least two protruding engagement ribs. Furthermore, the inner surface of the receptacle can advantageously abut against the at least two engagement ribs. The at least two engagement ribs advantageously predetermine the abutment of the metal body against the mating member in the region of the receptacle. Furthermore, the at least two engagement ribs predetermine the maximum deflection of the at least one spring element in the direction of the engagement section, because the inner surface of the receptacle abuts against the engagement ribs that join the engagement surfaces in the region of the at least two engagement ribs. For deflector assembly purposes, at least one spring element can be deflected in the direction of the engagement section via the protruding engagement ribs. When the at least one spring element is arranged in the opening, it is also feasible for assembly purposes for the at least one spring element to extend beyond the opening and turn into the interior region of the opening. Thus, at least two engaging ribs can advantageously predefine the abutment area of the metal body and the mating member in the region of the receiving portion.
[0025] In another embodiment, the receiving portion is formed by a rolled section extending toward the seatbelt groove. Since the metal body is preferably a metal stamping, the receiving portion can advantageously be formed by bending or rolling a region of the metal stamping. The mating section of the mating member is correspondingly formed to match the rolled section extending toward the seatbelt groove. In this way, anti-rotation of the metal body relative to the mating member can be advantageously provided. Furthermore, a form-fit connection can advantageously be formed by the rolled section. Additionally, a seatbelt support surface can advantageously be formed by the surface of the rolled section facing away from the inner surface of the receiving portion.
[0026] In another advantageous embodiment of the invention, the maximum deflection of the at least one spring element is predetermined by a mating surface and / or by a mating rib. In the assembled deflector, preferably, the inner surface of the receptacle at least partially abuts against the mating surface or one or more of the at least two mating ribs forming the mating surface. If relative movement occurs between the mating surface and the inner surface of the receptacle, the at least one spring element can also desiccate stress by abutting against the inner surface of the receptacle between the metal body and the mating member. The maximum deflection of the spring element in the direction of the mating surface, and therefore the spring force at which the at least one spring element exerts its maximum effect, can advantageously be predetermined by the embodiment of the mating rib or mating surface.
[0027] The invention and its technical environment are explained below by way of example with reference to the accompanying drawings. The drawings schematically illustrate:

[0033] Figure 6 :according to Figure 4 The cross-sectional view shows the deflector according to the invention, and
[0034] Figure 7 :according to Figure 5 The cross-sectional view shows the mating parts.
[0035] The deflector 1 shown in the accompanying drawings includes a metal body 2 having a fixed opening 3 and a seatbelt slot 4, and a mating member 5 connected to the metal body 2. For this purpose, the metal body 2, designed as a metal stamping, has a receiving portion 6 with an inner receiving surface 8. The receiving portion 6 is formed by a rolled section 15. The engaging section 7 of the mating member 5 has an engaging surface 9, wherein the engaging section 7 and the engaging surface 9 are formed corresponding to the receiving portion 6 and the inner receiving surface 8, such that the engaging section 7 can be arranged in the receiving portion 6 and the mating member 5 can be connected to the metal body 2. Two openings 11 are formed on the engaging surface 9, in which two spring elements 10 are arranged integrally with the mating member 5. The spring elements 10 abut against the inner receiving surface 8. On the side of the rolled section 15 facing away from the inner receiving surface 8, a seatbelt support surface 13 is formed by the surface 12 of the metal body 2. Furthermore, the mating surface 9 has five mating ribs 14, which are also formed corresponding to the receiving portion 6, such that the five mating ribs 14 abut against the inner surface 8 of the receiving portion. Additionally, the metal body 2 has a clamping protrusion 23 above the fixing opening 3.
[0036] The mating member 5 is designed to consist of an upper section 18 and a lower section 19. The upper section 18 is cut out corresponding to the fixing opening 3 of the metal body 2, allowing the fastening device to be guided through the mating member 5 accordingly. Furthermore, the upper section 18 has a seatbelt section 20 that engages in the seatbelt slot 4 of the metal body 2. The upper section 18 of the mating member 5 is connected to the lower section 19 via two connecting arms 17, each laterally arranged beside the fixing of the simulated fixing opening 3. The lower section 19 has an engagement section 7 with a spring arm 10 and an engagement rib 14. A decorative profile 21 is laterally attached to the mating member 5, separating from the lower section 19. Additionally, the mating member 5 has a hook 16 that engages the clamping protrusion 23 of the metal body 2 from the rear when the deflector 1 is in the assembled state. Furthermore, the mating member 5 has three support elements 24 and three additional hooks 22 pointing towards the fixing opening 3 on the rear side.
[0037] The mating component 5 is secured to the metal body 2 via a hook 16, which engages the clamping protrusion 23 of the metal body 2 from the rear above the fixing opening 3. Furthermore, three additional hooks 22 of the mating component 5 engage the metal body 2 from the rear in the region of the fixing opening 3. Here, the three additional hooks 22 are supported laterally from the inside of the fixing opening 3 of the metal body 2 and engage the metal body 2 from the rear in a circumferentially staggered manner. The additional hooks 22 are regularly distributed around the circumference of the fixing opening 3. Three rearwardly arranged support elements 24 of the mating component 5 support a portion of the vehicle and, together with a fixing device that can be inserted into the fixing opening 3, pre-tighten the deflector 1 to the portion of the vehicle. In this way, the deflector 1 is prevented from uncontrollably stopping on the vehicle. Here, the three support elements 24 are staggered relative to the additional hooks 22 and evenly distributed around the circumference of the fixing opening 3, thereby resulting in an advantageously uniform connection or support for the deflector 2.
[0038] exist Figure 1 The metal body 2 shown in the figure is in Figure 2 The mating parts 5 shown in the figure are formed together in Figure 3 The deflector 1 is shown in the diagram. The metal body 2 and the mating part 5 are attached to each other in multiple areas, as can be seen from... Figure 4 exist Figure 6 As shown in the cross-sectional view, the mating member 5 engages with the seatbelt groove 4 via the seatbelt section 20. Furthermore, the mating member 5 engages with the metal body 2 in the area of the fixed opening 3, wherein three additional hooks 22 of the mating member 5 engage with the fixed opening 3 of the metal body 2. The mating member 5 and the metal body 2 are additionally held together via the additional connection of the hooks 16 on the clamping protrusion 23.
[0039] Furthermore, the connection between the metal body 2 and the mating part 5 and the deflector 1 is achieved by engaging the receiving portion 6 via the engaging section 7. Here, the engaging surface 9 has five protruding engaging ribs 14, such that the engaging ribs 14 abut against the inner surface 8 of the receiving portion 6 of the metal body 2. The receiving portion 6 is formed here by the rolling section 15 of the metal body. Advantageously, the metal body 2, designed as a metal stamping part, can be bent or rolled during its manufacturing, such that the receiving portion 6 is bent inward with respect to the inner surface 8 of the receiving portion. In addition, a seat belt support surface 13 is provided on the surface 12 of the metal body 2 facing the inner surface of the receiving portion in the region of the seat belt groove 4. At the same time, the surface 12 or the seat belt support surface 13 restricts the seat belt groove 4 in one direction. For example, it is possible to... Figure 6 As can be seen, on the front side, the mating part 5, with the seat belt section 20, also engages with the seat belt groove 4 of the metal body 2 in the area of the seat belt support surface 13, so that the seat belt can advantageously slide along the mating part 5 and can avoid wear on the sharp edges of the seat belt groove 4.
[0040] Two spring elements protruding from the mating surface 9 or the mating rib 14 according to Figure 7 Each is arranged in the opening 11. If the mating part 5 is connected to the metal body 2 to form a deflector 1, the spring element 10 presses against the inner surface 8 of the receiving portion 6, and can advantageously compensate for unevenness or misalignment of the rolling section 15 of the metal body 2 and prevent tilting during assembly. Specifically, in... Figure 6 As can be seen, the spring element 10 contacts the inner surface 8 of the receiving portion. Furthermore, the inner surface 8 of the receiving portion rests against five engaging ribs 14 that mimic the contour of the inner surface 8 of the receiving portion. The spring element 10, in particular, is... Figure 6 As can be seen, it is aligned with the engaging rib 14, which segmentally forms the engaging surface 9. In this case, the spring element 10 of the deflector 1 deflects to the maximum extent toward the interior of the engaging section 7, wherein the spring element 10 is partially arranged in the corresponding opening 11.
[0041] If the mating part 5 stops on the metal body 2 at this time, the tension of the spring element 10 prevents a rattling sound. Furthermore, the two staggered spring elements 10 prevent uncontrolled stopping or separation of the metal body 2 and the mating part 5 on one side. For example, if the metal body 2 and the mating part 5 are... Figure 2 When the right side of the spring element 10 moves away from the inner surface 8 of the receiving portion and the connecting rib 14, the spring element 10 on the right side can deflect accordingly and remain against the inner surface 8 of the receiving portion, thereby providing tension. The same applies when the receiving portion 6 formed by the rolling section 15 has an irregularly shaped inner surface 8.
