[0002] ISOFIX CONNECTION, BELT RACK ARRANGEMENT AND RECREATIONAL VEHICLE

[0003] The invention relates to a recreational vehicle, in particular a mobile home, with at least one seat belt anchorage assembly. Furthermore, the invention relates to a seat belt anchorage assembly with an Isofix connection for such a recreational vehicle and a related Isofix connection.

[0004] A motorhome with a belt rack arrangement is known from DE 20 2020 106 815 U1. The belt rack arrangement has a belt rack and a restraint system. The restraint system has a belt system and a retaining fitting for a child seat arranged on the belt rack. The seat lock can be designed, for example, according to the Isofix standard or in another way. Children can be secured in the respective child seat with the safety belt system. A child seat can have a seat element and a seat holder. The seat element can be, for example, a seat shell or a baby carrier. The seat holder can have one or more extendable retaining arms with fixing elements at the ends, for example locking claws. The seat holder can interact with several individual retaining fittings on the belt rack and, when engaged, form the seat lock.

[0005] Regulation No. 14 of the Economic Commission for Europe of the United Nations (UNECE) (Official Journal of the European Union of 19 August 2015, I., 2018 / 27) describes uniform conditions for the approval of vehicles with regard to safety belt anchorages, Isofix anchorage systems, Isofix top tether anchorages and i-Size seating positions.

[0006] A seat belt anchor and an Isofix connection can be used as a restraint system for a bench seat, particularly in a second or third row. A welded steel construction can be used. In safety class N1, the Isofix connection weighs approximately four kilograms. Installation can be achieved by clamping or screwing the Isofix bracket to the vertical struts of the seat belt anchor. Depending on the design, several screw directions are used. The Isofix connection is therefore a large component that allows for one or two Isofix positions and is approximately as wide as the belt frame.

[0007] However, such designs have the disadvantage of limited installation due to restricted accessibility and different screw directions. Furthermore, the design spans both seats or the entire width of the belt frame, resulting in a high weight when only one Isofix seat is required or permitted. Furthermore, different positions for different seat widths are only possible with structural adjustments and thus with different parts.

[0008] The present invention is based on the object of specifying an Isofix connection for a belt bracket of a recreational vehicle, in particular a mobile home, a belt bracket arrangement for a recreational vehicle and a recreational vehicle which enable an improved design and functioning.

[0009] The object is achieved by an Isofix connection having the features of independent patent claim 1, a belt bracket arrangement having the features of patent claim 7, and a recreational vehicle having the features of patent claim 10. Advantageous developments of the invention are specified in the subclaims.

[0010] The object is achieved by an Isofix connection for a belt bracket of a recreational vehicle, in particular a mobile home, with a connecting strut, a first bracket and a second bracket, wherein the first bracket and the second bracket are directly connected to the connecting strut and wherein the connecting strut is designed such that the connecting strut can be connected to the belt bracket.

[0011] Furthermore, the object is achieved by a belt support assembly for a recreational vehicle, in particular a mobile home, comprising a belt support and at least one Isofix connection connected to the belt support. Furthermore, the object is achieved by a recreational vehicle, in particular a mobile home, comprising at least one such belt support assembly. It is advantageous that the first bracket and / or the second bracket are connected to the connecting strut in a materially bonded and / or form-fitting manner. This achieves high strength.

[0012] It is advantageous that at least one connecting tab is formed on the connecting strut, which has at least one through-opening, and that the connecting strut can be connected to the belt bracket by means of a fastening bolt extending through the through-opening. It is further advantageous that the at least one through-opening is designed as a through-bore or as an elongated hole. This enables reliable and simple assembly. Furthermore, good accessibility is achieved. If the through-opening is designed as an elongated hole, advantageous adaptation to different applications, in particular belt bracket widths, or designs of the belt bracket can be achieved. The belt bracket can in particular be formed at least substantially from a fiber-reinforced plastic.

[0013] Furthermore, it is advantageous that at least one further connecting link is formed on the connecting strut, that the first bracket is connected to the connecting strut at the connecting link, and that the second bracket is connected to the connecting strut at the further connecting link. Specifically, a through-hole configured as a through-hole can be provided on one connecting link, while a through-hole configured as an elongated hole is provided on the other connecting link. This results in a particularly advantageous assembly.

[0014] It is advantageous that at least one stiffening rib is formed on the connecting strut, extending from the first bracket on the one hand to the second bracket on the other, and that the stiffening rib extends at least approximately in and / or opposite to the extension of the first bracket and the extension of the second bracket. This advantageously allows for targeted and, if necessary, direction-dependent stiffening of the connecting strut, while simultaneously achieving weight optimization.

[0015] Advantageously, the belt bracket can be designed so that the Isofix connection is positioned on the front side of the belt bracket and bolted to it. This allows for particularly convenient installation.

[0016] It is also advantageous to have at least two adjacent Isofix attachments connected to the seat belt bracket. This allows for two Isofix seats, resulting in an optimized design, particularly with regard to weight.

[0017] Thus, depending on the design, one or more of the following features and advantages can be realized. The Isofix connection can serve exactly one Isofix seat, but still have both required brackets. The Isofix connection can be very lightweight. The Isofix connection can be designed to be less susceptible to tolerance problems because there are fewer interfaces to the belt frame. The Isofix connection can be attached and screwed to the belt frame from the front. The Isofix connection can also be used multiple times as a component on a belt frame. This advantageously allows for the implementation of multiple Isofix seats.

[0018] In addition, different seating group widths and different Isofix positions, for example in the transverse direction of the vehicle, can be realized through elongated holes provided on the connecting strut and / or different drilling positions. Such elongated holes and / or different drilling positions are preferably provided on the at least one connecting plate. Thanks to this advantageous design, it is possible to ensure that the Isofix connection does not need to encompass the belt frame or other parts. The Isofix connection can also be designed so that it does not extend backwards. This does not restrict the installation space of structures behind it. Furthermore, simple repair and replacement can be realized. Accordingly, simple assembly and disassembly can be enabled.

[0019] Further advantages and details of the invention are explained in more detail with reference to the exemplary embodiments illustrated in the schematic figures. In the figures: Fig. 1 shows an Isofix connection in a schematic, three-dimensional representation, according to an exemplary embodiment of the invention, showing a design with through-holes configured as through-holes;

[0020] Fig. 2 shows the Isofix connection shown in Fig. 1 in a modified embodiment, wherein one through-hole is designed as a through-hole and the other through-hole is designed as an elongated hole to enable attachment; and

[0021] Fig. 3 shows a belt bracket arrangement for a recreational vehicle in an excerpted, schematic representation according to a possible embodiment of the invention.

[0022] Fig. 1 shows an Isofix connection 1 for a belt bracket 2 (Fig. 3) of a recreational vehicle 3 in a schematic, spatial representation according to an exemplary embodiment. The recreational vehicle 3 can be designed, in particular, as a mobile home. The Isofix connection 1 preferably serves for a belt bracket 2 of such a recreational vehicle 3.

[0023] The Isofix connection 1 comprises a connecting strut 4, a first bracket 5, and a second bracket 6. The first bracket 5 and the second bracket 6 are each directly connected to the connecting strut 4. In the assembled state, the connecting strut 4 is connected to the belt bracket 2, so that the brackets 5, 6 are then attached to the belt bracket 2 via the connecting strut 4. The brackets 5, 6 can be connected to the connecting strut 4 in a material-to-material and / or form-fitting manner.

[0024] In this embodiment, two connecting plates 7, 8 are formed on the connecting strut 4. The connecting plate 7 is located on the first bracket 5. The connecting plate 8 is located on the second bracket 6. The connecting plates 7, 8 have through-openings 9, 10, as also illustrated in Fig. 2. Fig. 1 shows fastening bolts 11, 12, which conceal the through-openings 9, 10 in the illustration. The fastening bolts 11, 12 extend through the through-openings 9, 10 of the connecting plates 7, 8.

[0025] The fastening bolts 11, 12 can be designed, in particular, as screw bolts 11, 12. The fastening bolts 11, 12 enable reliable fastening to the belt bracket 2. Since the connecting tabs 7, 8 are located in the area of ​​the brackets 5, 6, this results in advantageous force transmission from the brackets 5, 6 to the fastening bolts 11, 12 and thus to the belt bracket 2 when the brackets 5, 6 are subjected to heavy loads, for example, in a crash.

[0026] It is particularly advantageous if the bracket 5 is connected directly to the connecting plate 7. Furthermore, it is particularly advantageous if the bracket 6 is connected directly to the connecting plate 8. This ensures a high load-bearing capacity of the Isofix connection 1 at its brackets 5, 6 when installed.

[0027] The connecting strut 4 has a stiffening rib 14. The brackets 5, 6 extend in mutually parallel extensions 15, 16. The stiffening rib 14 is designed such that it extends in an extension 17 that is at least approximately parallel to the extensions 15, 16. Furthermore, the stiffening rib 14 extends from a first side 18 on the connecting plate 7 to a second side 19 on the connecting plate 8. The first side 18 is also the first side 18 of the connecting strut 4. Furthermore, the second side 19 is also the second side 19 of the connecting strut 4. In particular, the stiffening rib 14 thus extends, on the one hand, over the first bracket 5 and, on the other hand, over the second bracket 6.

[0028] The design of the Isofix connection 1 is further described below with reference to Fig. 2.

[0029] Fig. 2 shows the Isofix connection in a schematic, three-dimensional representation according to a modified embodiment. In this embodiment, the through-opening 9 is designed as an elongated hole 9. The through-opening 10 is designed as a through-bore 10. The elongated hole 9 allows a certain degree of variability in the fastening, since the fastening bolt 11 can be mounted along the elongated hole 9 at a suitable location. In contrast, in the exemplary embodiment shown in Fig. 1, the through-opening 9 is also designed as a through-bore 9, as is illustrated by the through-opening 10. The through-opening 10 is designed as a through-bore 10 in both the exemplary embodiment illustrated in Fig. 1 and the exemplary embodiment illustrated in Fig. 2.

[0030] To increase the variability, instead of an elongated hole 9, as shown in Fig. 2, a design with several through holes arranged next to one another can also be realized.

[0031] Fig. 3 shows a belt support assembly 20 for the recreational vehicle 3 in a partial, schematic representation according to a possible embodiment of the invention. The belt support assembly 20 comprises a belt support 2 and Isofix attachments 1, T connected to the belt support 2. Each Isofix attachment 1 serves for a seat. The Isofix attachments 1 can be implemented according to the embodiments described with reference to Figs. 1 and 2.

[0032] The Isofix attachments 1, T are attached to the belt bracket 2 from a front side 21 of the belt bracket 2. When installed, the Isofix attachments 1, 1' are also screwed to the belt bracket 2 via fastening bolts 11, 12. To simplify the illustration, only the fastening bolts 11, 12 are marked.

[0033] This allows for multiple Isofix attachments 1, 1' to be mounted side by side in a suitable manner. This results in an optimized design that allows for reduced material usage, since an optimized connecting strut 4 can be implemented for each Isofix attachment 1, 1'. This also results in weight savings.

[0034] In particular, a certain distance 25 of the connecting strut 4 from one side 26 of the belt support 2 can be specified. Furthermore, a certain distance 27 between the Isofix connections 1, 1' can be specified. This allows for material savings compared to a design in which a strut extends from the side 26 of the belt support 2 to an opposite side 28 of the belt support 2. The invention is not limited to the described embodiments.
