Description

TECHNICAL AREA

[0001] The present disclosure relates generally to the field of anchoring arrangements. In particular, the present disclosure relates to an anchoring arrangement for a child seat in a vehicle, which supports the anchoring wire and distributes the load or stress exerted by the anchoring wire evenly onto a mounting bracket connected to the anchoring arrangement. BACKGROUND

[0002] The current ISOFIX cable arrangement in vehicles consists of an ISOFIX cable and a mounting bracket for the ISOFIX system. The current design of the ISOFIX mounting bracket requires a cutout or opening, which can be rectangular, round, or otherwise shaped, to allow the ISOFIX cable to be inserted and welded in place.

[0003] The ISOFIX system is used in the automotive industry to secure child car seats. However, in an accident, the child car seat transfers significant loads to the ISOFIX cable. This stress can cause the ISOFIX wires to deform. Due to the design of the cutout in the mounting bracket, a high local stress concentration occurs at the bracket, which can pose a significant problem. This high stress concentration can frequently lead to material separation of the ISOFIX bracket, compromising the safety and integrity of the child car seat installation system.

[0004] To mitigate this problem, manufacturers have so far resorted to adding extra material to the bracket or using higher-grade materials. While these methods can reduce stress concentration and prevent material separation, they also lead to higher manufacturing costs per vehicle.

[0005] Efforts have been made in the past to secure child car seats in vehicles; for example, patent EP2384925A1 discloses a seat back body with an anchoring device for securely attaching a child car seat. The anchoring device comprises an anchoring wire that is guided between the seat back body and a retaining head of a bolt. The anchoring wire is connected to the seat back body by means of hooks. The pin contributes to fixing the anchoring wire, which includes a bridge section with a central part that projects towards the front of the body and forms a straight anchor to secure the attachment of a child car seat in a motor vehicle. However, the cited reference does not offer a reliable and cost-effective solution to overcome the aforementioned problems.

[0006] Therefore, there is a need to overcome the aforementioned disadvantages, shortcomings and limitations of existing Isofix arrangements by offering an improved, reliable and cost-effective solution that can withstand accident loads without causing high local stress concentrations and material separation. OBJECTS OF INVENTION

[0007] A general purpose of the present disclosure is to prevent failure of the arrangement of ISOFIX wires in order to ensure the secure fastening of child car seats in vehicles.

[0008] One objective of the present disclosure is to develop an arrangement of ISOFIX wires that can withstand significant accident loads without deforming or causing high local stress concentrations, thus ensuring the safe fastening of child seats in vehicles.

[0009] One purpose of the present disclosure is to minimize material delamination and stress on the ISOFIX mounting bracket, which may help to prevent failure of the ISOFIX wire assembly in accidents and increase the durability and reliability of the assembly.

[0010] One purpose of the present disclosure is to reduce manufacturing costs by eliminating the need for additional or higher-quality materials in the Isofix mounting bracket.

[0011] One objective of the present disclosure is to improve the structural integrity of the Isofix arrangement by creating a robust design of the fixing bracket that distributes the load more evenly and thus reduces the likelihood of failure in accidents.

[0012] One objective of the present disclosure is to ensure compliance with safety standards by developing an Isofix arrangement that meets or exceeds applicable safety standards and regulations. SUMMARY

[0013] Aspects of the present disclosure relate to the field of anchoring arrangements. In particular, the present disclosure relates to an anchoring arrangement for a child seat in a vehicle, which supports the anchoring wire and evenly distributes the load or stress exerted by the anchoring wire on a mounting bracket connected to the anchoring arrangement.

[0014] According to one aspect of the present disclosure, an anchoring arrangement is described. The arrangement comprises a fastening arrangement with one or more slots, wherein the fastening bracket is suitable for fastening to a first component. Furthermore, the bracket comprises a base surface defining the shape of the bracket and an inclined surface at the edge of the one or more slots, projecting from the base surface at a predefined angle. The arrangement also includes an anchoring wire that can be passed through the one or more slots and fastened to the bracket. Accordingly, the inclined surface of the one or more slots is configured to support the wire and to distribute the load or stress exerted by the wire on the bracket uniformly when the wire engages.

[0015] In one aspect, the predefined angle can be between 30 and 70 degrees. Furthermore, the height of the inclined surface relative to a plane of the base can be between 2 and 8 mm.

[0016] Furthermore, the inclined surface can have a flat or curved profile, or a combination of both.

[0017] In one aspect, one or more slots can be provided on a body of the base surface of the bracket. Another aspect is that one or more slots can be formed on an edge of the base surface of the bracket.

[0018] The bracket can be manufactured from a single plate of a predefined material, whereby one or more slots can be formed on the base surface and the edge of the corresponding slots can be machined to form the inclined surface.

[0019] Furthermore, the ends of the anchoring wire can extend through one or more slots and be welded to the bracket, with the mounting bracket being attached to the first component. Additionally, a section of the anchoring wire can be attached to a second element inside the vehicle.

[0020] In one case, the anchoring arrangement can be an ISOFIX arrangement of a vehicle, where the first element can be a body or seat of the vehicle and the second element can be a child seat.

[0021] Accordingly, the inclined surface of one or more slots can be configured so that, in the event of an impact on the vehicle, the wire is supported on the bracket in the event of a load or stress, and the load or stress is distributed evenly over the inclined surface, thereby reducing deformation of the wire and preventing cracks in the bracket.

[0023] The embodiments described herein relate to an anchoring arrangement for a child seat in a vehicle, which supports the anchoring wire and distributes the load or tension exerted by the anchoring wire evenly onto a mounting bracket connected to the anchoring arrangement.

[0024] With reference to Fig. In Figures 1A to 1C, the proposed anchoring arrangement “arrangement” is disclosed. The arrangement 100 may include a fastening bracket 102 (also referred to herein as wire 104 or Isofix wire 104) which can be adapted to be attached to a first element 202, as shown in Fig. Figure 2 shows that the arrangement 100 can further comprise an anchoring wire 104 (also referred to here as wire 104 or Isofix wire 104) which can be passed through and attached to the bracket 102. Furthermore, a segment 104-1 of the anchoring wire 104 (which is attached to the bracket 102) can be attached to a second element 204, thereby anchoring the first element 202 to the second element 204. In one embodiment, the arrangement 100 can be an Isofix arrangement of a vehicle, wherein the first element 202 can be a body part or a seat of the vehicle and the second element 204 can be a child seat. Accordingly, the arrangement 100 can anchor the child seat 204 to the body part / seat 202 in the interior of the vehicle.

[0025] In one embodiment, the holder 102 comprises a base surface 102-1, which defines the shape of the holder 102 and may also include one or more slots (S). The holder 102 may further have an inclined surface 102-2 at the edge of the corresponding slots (S), which may project from the base surface 102-1 at a predefined angle to form a profiled, lip-shaped interface at the edge of the slots (S) of the holder 102. In one embodiment, the predefined angle may be between 30 and 70 degrees, but is not limited to this range. Furthermore, the height of the inclined surface 102-2 with respect to a plane of the base surface 102-1 is in a range of 2 to 8 mm, but is not limited to such values. In addition, the inclined surface 102-2 of the holder 102 may have any flat profile or a combination of a flat and a curved profile.

[0026] In one embodiment, the base surface 102-1 or the bracket 102 can have a predefined shape based on the surface of the first element / BiW / seat 202 to which the bracket 102 is to be attached. For example, in an exemplary embodiment, if the bracket 102 is to be attached to a flat side of the first element / BiW / seat 202, the base surface 102-1 of the bracket 102 can have a substantially flat profile, as shown in the Fig. 1A and Fig. 3A shown. Furthermore, in an exemplary embodiment (not shown), if the bracket 102 is to be attached to an edge or corner of the first element / BiW / seat 202, where two adjacent sides are at right angles (90-degree angles) to the corresponding edge or corner, the base surface 102-1 of the bracket 102 can also have a substantially L-shaped profile, so that the base surface 102-1 of the bracket 102 extends at least partially onto the two adjacent sides of the first element / BiW / seat 202. The base 102-1 of the bracket 102, which has a flat shape, can also be attached to a flat surface at the edge of the first element / BiW 202, so that the base 102-1 of the bracket 102 with the slots (S) at the edge of the base 102-1 remains on the corresponding side of the first element / BiW / seat 202.

[0027] Furthermore, in another exemplary embodiment, if the bracket 102 is to be attached to an edge or corner of the first element / BiW / seat 202, where two adjacent sides form a non-right angle at the corresponding edge or corner, the base surface 102-1 of the bracket 102 can also have a substantially V-shaped profile with the same non-right angle between the inclined sides of the bracket 102, as shown in Fig. 1B shown, so that the base area 102-1 of the support 102 extends at least partially onto two adjacent sides of the first element / BiW / seat 202.

[0028] In one embodiment, the slots (S) can be provided on the body of the base surface 102-1. In such an embodiment, the slots (S) can remain perpendicular to the body, as shown in Fig. Figure 1A shows how the bracket 102 is to be attached to a flat side or to the edges / corners of the first element 202. However, the slots (S) can also run essentially parallel to the base 102-1, as shown in the Fig. 1B and Fig. 1C, if the support 102 is to be attached to the edges / corners of the first element 202. In another embodiment, the containers (S) can be attached to the edges of the base 102-1, as shown in Fig. Figure 1C shows that in such an embodiment the slots (S) can run substantially parallel to the base surface 102-1. Furthermore, in one embodiment the slots (S) can be circular, rectangular, oval and / or square, but are not limited to such shapes.

[0029] In one embodiment, the bracket 102 can be manufactured from a single plate of a predefined material, wherein the slots (S) can be formed on the base surface 102-1 and the edge of the corresponding slots (S) can be machined to form the inclined surface 102-2. In an exemplary embodiment, the anchoring wire 104 can be a single solid wire or consist of a bundle of wire strands, which can be made of, but are not limited to, steel, metal, and alloys. In an exemplary embodiment, the bracket 102 can be made of, but is not limited to, steel, metal, and alloys.

[0030] In Fig. Figure 1A represents the ends of the wire 104 welded to the support 102, while figure 108 represents the load of the wire 104 distributed over the inclined surface. Fig. 1B represents the ends of wire 104, which are welded to the holder 102, and 112 represents a non-right angle. In one embodiment, the ends E1, E2 (in Fig. 4 shown) of the anchoring wire 104 is passed through the slots (S) of the bracket 102 and welded to the bracket 102, as shown in Fig. Figures 1A to 1C show the mounting bracket 102 being further attached or welded to the first element / bicycle / seat 202, so that the corresponding ends of the anchoring wire 104 remain attached to the first element / bicycle / seat 202. In one embodiment, the bracket 102 may additionally have holes H to allow the mounting of the bracket 102 to the first element 202 using fasteners (not shown). Furthermore, a segment 104-1 of the anchoring wire 104 may be attached to the second element / child seat 204 inside the vehicle, thereby anchoring the child seat 204 to the bicycle / seat 202. In one embodiment, as shown in Fig. As shown in Figure 4, the wire 104 can be twisted from the middle segment 104-2 such that the outer ends E1, E2 of the wire 104 remain on the same side and substantially parallel to each other. The two ends E1, E2 of the twisted wire 104 can be inserted into slots (S) and welded to the holder 102, as shown in Figure 4. Fig. 1A to 1C. Furthermore, segment 104-1 of wire 104 can be anchored to the second element / child seat 204, as shown in Fig. 2 shown.

[0031] The person skilled in the art recognizes that, when a load or tension is applied to the support 102 by the wire 104, the inclined surface 102-2 of the slots (S) can support the wire 104 on the support 102 in the event of an accident upon impact with the vehicle, as shown in Fig.1A shows that direct contact with the base surface 102-1 of the bracket 102 is prevented, and that stress concentration is prevented and the load or stress is distributed evenly over the inclined surface 102-2, thereby reducing the deformation of the wire 104 and preventing cracks in the bracket 102.

[0032] This disclosure overcomes the disadvantages, shortcomings, and limitations associated with the existing Isofix wire fastening arrangement by providing an improved, reliable, and cost-effective anchoring arrangement that can support the anchor wire (Isofix) and withstand crash loads without causing high local stress concentrations and material separation in the fixing bracket. This allows the arrangement to withstand significant crash loads without deformation or high local stress concentrations, ensuring the safe installation of child car seats in vehicles. Furthermore, the arrangement minimizes material separation and stress on the fixing bracket, increases the durability and reliability of the fastening, and reduces manufacturing costs, as no additional or higher-grade materials are required for the fixing bracket.

[0033] It is obvious to the person skilled in the art that the proposed anchoring arrangement, which serves as an Isofix arrangement for the secure anchoring of a child seat to the car seat / seat of a vehicle, although elaborated in various embodiments and representations of the present disclosure, that the proposed anchoring arrangement can also be used for anchoring any other vehicle or non-vehicle component to any structure and that all such embodiments fall within the scope of the present disclosure without restriction.
