Description

FIELD OF THE INVENTION

[0001] The invention relates to an adapter according to the preamble of claim 1. TECHNICAL BACKGROUND

[0002] During vehicle development, measurement equipment typically needs to be transported on board the vehicle during test drives. The measurement equipment is often located inside the vehicle, allowing access during test drives, for example. To prevent the measurement equipment from slipping during the test drive, it is secured.

[0003] Lashing is a relatively lengthy process, and it must be done with the utmost care to ensure the measuring equipment is securely connected to the vehicle while driving. The problem is that lashing eyes are not available everywhere on the vehicle, so lashing may only be possible under difficult conditions. STATE OF THE ART

[0004] A first option for better securing the measuring equipment is shown in DE 20 2019 100 463 U1, which is fully incorporated into this application. However, the adapter for attaching the measuring equipment described in this document also has certain weaknesses. For example, the adapter can only be installed on rear seats and not, for example, on the front passenger seat. OBJECT OF THE INVENTION

[0005] Against this background, it is the object of the invention to provide an adapter for a motor vehicle which connects objects connected to the adapter, such as measuring technology, to the motor vehicle quickly and easily and is independent of existing fastening systems in the motor vehicle. INVENTIVE SOLUTION

[0006] A solution to this problem is provided by the main claim.

[0007] According to the invention, an adapter for intended attachment to a seat of a motor vehicle is proposed. This adapter has a holding plate, wherein at least one fastening device for attaching an object to the adapter is arranged on the holding plate. The adapter is characterized in that it comprises a first belt receptacle and a second belt receptacle, wherein one belt receptacle partially accommodates the lap belt section and the other belt receptacle partially accommodates the chest belt section of a motor vehicle belt. The motor vehicle belt is preferably a belt provided as standard on a motor vehicle and / or a belt which is preferably intended for an average Central European. The motor vehicle belt is preferably a safety belt or seat belt with a buckle tongue, a belt buckle and a deflector. The motor vehicle belt is preferably a three-point belt.

[0008] The first belt receptacle preferably partially accommodates the lap belt section of the motor vehicle belt and the second belt receptacle preferably partially accommodates the chest belt section. However, it is possible, although not preferred, for the first belt receptacle to partially accommodate the chest belt section and the second belt receptacle to partially accommodate the lap belt section. The lap belt section and the chest belt section are preferably to be differentiated from one another as follows: The lap belt section is preferably the section of the belt that runs between the lower, fixed anchorage of the belt - preferably below the seating surface of the seat - up to the buckle tongue, which is engaged in the belt buckle. The chest belt section is the section of the belt that runs between the buckle tongue, which is engaged in the belt buckle, and the deflector.

[0009] In the context of the invention, “receiving” the belt in relation to the belt receptacles means at least partially guiding the belt section, at least partially enclosing the belt section and / or at least partially supporting the belt section.

[0010] Because the two belt sections can be attached to two different belt mounts, it is possible to easily secure the adapter in the respective seat using only the vehicle's belt. This means that attaching the adapter, for example, for a test drive, is independent of any additional fastening systems in the vehicle and depends only on the presence of a vehicle's belt. This vehicle belt is standard on every seat in most cars and thus also allows for attachment to the front passenger seat of a vehicle, which normally does not have additional fastening systems. PREFERRED TRAINING OPPORTUNITIES FOR THE INVENTION

[0011] A preferred embodiment of the adapter includes a support bracket on the side facing the seat back for additional support of the adapter against the seat back. This provides a second, additional support, in addition to securing the adapter with the vehicle seat belt, which primarily prevents rotation of the adapter.

[0012] It is also particularly preferred if the support bracket includes a handle for holding the adapter. This handle facilitates installation and removal of the adapter in the vehicle and also makes it easier to carry.

[0013] Furthermore, it is particularly preferred if the adapter includes a retaining bracket on the side facing away from the seat back. This retaining bracket facilitates installation and removal of the adapter in the vehicle and also allows the adapter to be carried, especially in conjunction with the support bracket's handle.

[0014] Furthermore, it is particularly preferred if the retaining bracket is formed by a cutout in the retaining plate. This allows the retaining bracket to be implemented in a simple and cost-effective manner. For this purpose, the retaining plate preferably has a projection on the side opposite the seat back.

[0015] A further preferred embodiment of the adapter is that each fastening device of the holding plate is a circular hole, to which an elongated hole of smaller diameter is connected, which runs in the direction of the side facing away from the seat back. The elongated hole preferably runs parallel to the long side of the adapter and is preferably perpendicular to the short side of the adapter. These fastening devices can thus be used in a simple manner for many fastening options. It is preferred that an equivalent adapter plate with attached objects is already prepared in the laboratory or outside the motor vehicle. This adapter plate preferably has mushroom-shaped projections on its underside, which can be inserted into the circular holes of the fastening devices.The underside of the adapter plate then rests preferentially on the top side of the retaining plate and the slender part of the mushroom-shaped projections can be guided in the elongated holes to their closed end, whereby the adapter plate is held in the fastening devices on the retaining plate.

[0016] Furthermore, it is particularly preferred if the circular hole is at least partially reinforced in its peripheral area by a mushroom-shaped guide mounted on the underside of the retaining plate. This mushroom-shaped guide serves as a simple centering stop when removing or undocking the adapter plate described above.

[0017] Furthermore, it is particularly preferred if the adapter comprises a multi-part—preferably a two-part—seat plate that is firmly connected to the retaining plate at a distance from the retaining plate. The seat plate is provided for placing the adapter on the seat surface of the vehicle seat. This provides a flat or at least partially flat support surface for the adapter on the seat, allowing the weight of the adapter to be more easily distributed across the seat.

[0018] Furthermore, it is particularly preferred if the distance between the seat plate and the support plate is not constant and the distance between the support plate and the seat plate decreases in the direction away from the seat back. This quasi-negative gradient of the support plate compared to the seat plate ensures that the gradient of the seat surface is at least substantially compensated for in a simple manner.

[0019] “Substantially balanced” means that the retaining plate, when properly attached to the seat, is preferably parallel to the base of the vehicle, whereby a deviation of no more than + / - 10°, particularly preferably of no more than + / - 5°, from the base is acceptable.

[0020] Furthermore, it is particularly preferred if the adapter preferably has a stiffener on each of its two long sides as a spacer between the seat plate and the retaining plate, and also has at least one additional, preferably even two, stiffeners in the area between the two long sides. These stiffeners thus contribute in a simple way to the stability of the adapter and also offer the possibility of providing the belt receptacles on them. This makes it easy to effectively ensure the distance between the two plates and also provide additional stiffening and stabilization of the adapter.

[0021] A further preferred embodiment of the adapter is that the first belt receptacle is located in the central region of the stiffeners. The first belt receptacle is thus preferably distributed across several stiffeners. The "central region" is preferably located - viewed in the longitudinal direction of the stiffeners - in the middle 50% of the length of the stiffeners, particularly preferably even in the middle 30% of the length of the stiffeners. This allows the stiffeners to simultaneously assume the function of the first belt receptacle in a simple manner, and sufficient space can be provided between the first and second belt receptacles so that the desired holding effect of the vehicle belt can be achieved.

[0022] Furthermore, it is particularly preferred if the first belt receptacle is formed by circular-arc cutouts in the stiffeners, each of which is connected to a preferably narrowing cutout, preferably a triangular cutout. The narrowing section is used here as a threading aid for the vehicle belt, while the vehicle belt, when installed as intended, rests permanently in the circular-arc cutout. The circular-arc cutout ensures that the belt is not potentially cut into by sharp edges at any point, and the belt can also spread out along the cutout and is preferably not compressed.

[0023] Furthermore, it is particularly preferred if the circular cutouts of the first belt receptacle are aligned. This is advantageous for simplifying the adapter's production, as only identical stiffeners need to be manufactured, and it also prevents the vehicle belt from being jammed by offset cutouts.

[0024] A further preferred embodiment consists in that the second belt receptacle is located in the end region of the stiffeners. The second belt receptacle is thus preferably distributed across several stiffeners. The "end region" is preferably located - viewed in the longitudinal direction of the stiffeners - in the last third of the length of the stiffeners, particularly preferably even in the last 20% of the length of the stiffeners and absolutely preferably at the free end of the stiffeners, which is on the side facing away from the seat back. This allows the stiffeners to simultaneously take on the function of the first belt receptacle in a simple manner and sufficient space can be provided between the first and second belt receptacles so that the desired holding effect of the motor vehicle belt can be achieved.

[0025] Furthermore, it is particularly preferred if the second belt receptacle is formed by circular-segment-shaped cutouts in the stiffeners. The vehicle belt thus preferably rests on the circular-segment-shaped cutout and is even preferably partially encompassed by it. The circular-segment-shaped cutout ensures that the belt is not potentially cut into by sharp edges at any point, and the belt can also spread out along the cutout and is preferably not compressed.

[0026] Furthermore, it is particularly preferred if the circular-segment-shaped cutouts of the second belt receptacle are aligned. This is advantageous for simplifying the adapter's production, as only identical stiffeners need to be manufactured, and it also prevents the vehicle belt from being jammed by offset cutouts.

[0027] Furthermore, it is particularly preferred if the seat plate has a projection on its side facing the seat back, which can be at least partially inserted into the gap between the seat back and the seat surface. This provides a simple assembly aid and additional fixation of the adapter to the seat, thereby preventing or reducing the likelihood of rotation or rising of the adapter.

[0028] Furthermore, it is particularly preferred if the seat plate is designed as a two-part, flat sheet metal part that is interrupted in the area of ​​the first belt receptacle. This makes it easy to create a gap that exposes the first belt receptacle and allows the vehicle belt to be threaded into this first belt receptacle.

[0029] Furthermore, it is particularly preferred if the connection of an object to the fastening device is detachable and, in particular, is a screw connection, a clamping device, or a bayonet connection. Thus, the adapter can be easily equipped with various objects.

[0030] Further possible embodiments, functions and advantages emerge from the dependent claims and / or the following description of the exemplary embodiment and / or with reference to the figures. A FURTHER OBJECT UNDERLYING THE INVENTION

[0031] Furthermore, the invention is based on the object of providing a system that is as flexible as possible, with which objects, such as measuring technology, can be quickly and easily mounted in the motor vehicle. THE FURTHER INVENTIONAL SOLUTION

[0032] A solution to this problem is provided by claim 22.

[0033] Here, a system is proposed which comprises the adapter according to the invention, an adapter plate, an additional adapter for attachment to a rear seat of the vehicle, preferably a support, and a holding plate for attachment in the trunk of the vehicle.

[0034] The adapter for attaching to the rear seat is described in the as yet unpublished application 20 2024 103 585.2, which is fully incorporated herein by reference. The corresponding application is filed as a supplementary document in addition to this application.

[0035] The mounting plate for mounting in the trunk of the vehicle is described in the as yet unpublished application 20 2024 001 249.2, which is fully incorporated into this disclosure. The corresponding application is filed as a supplementary document in addition to this application.

[0036] The system according to the invention is characterized in that the measuring technology and / or components associated with the measuring technology are preferably mounted entirely on the adapter plate. The adapter plate is preferably mounted via the mushroom-shaped projections of the adapter plate, which engage with the correspondingly cooperating fastening devices. The adapter plate can be mounted in the same way on the mounting plate of the adapter according to the invention on the rear seat, on the adapter of the passenger seat, or on the mounting plate in the trunk.

[0037] This makes it easy to create a flexible mounting system in which the measurement technology or associated components can be mounted on an adapter plate outside the vehicle, preferably even in the laboratory. In the vehicle, an adapter is then preferably already mounted on the front passenger seat, at least one adapter on one of the rear seats, and / or a mounting plate in the trunk. Depending on the test situation, the user can then flexibly decide which of the receiving components the adapter plate should be mounted on. Furthermore, the adapter plate can be installed and removed very quickly and easily, preferably without tools and simply by placing and sliding the adapter plate.

[0038] It should be emphasized here that connecting the adapter plate to the receiving parts via the mushroom-shaped projections and the corresponding receiving holes with elongated holes (mounting drilling directions) is preferred, but other mounting methods are also conceivable. The goal of the mounting is an easily removable yet secure connection to the receiving parts.

[0039] The Fig. 1 to Fig. 8 show a preferred embodiment of the adapter 1 and the associated components.

[0040] Fig. 1 and Fig. 2 initially show the adapter 1 in a state not attached to the seat. The adapter 1 comprises a retaining plate 2 with at least one fastening device 3. The retaining plate 2 preferably also has a retaining bracket 8 at the end facing away from the seat S, which is preferably a cutout in the retaining plate 2.

[0041] On the side facing the seat S, the holding plate 2 preferably carries a support bracket 6 on its underside, which, when attached to the seat, presses against the seat back S1 (see Fig. 3). The support bracket 6 is preferably a bent tubular construction, with its two open ends preferably each being received by a support bracket holder located on the underside of the holding plate 2 and not visible in the figures. The support bracket 6 preferably also includes a handle 7.

[0042] The seat plate 10 is preferably designed in two parts as a flat part (see Fig. 6) and, when attached to the seat, preferably rests essentially completely on the seat surface S2 (see Fig. 3). Between the retaining plate 2 and the seat plate 10 are stiffeners 11—four stiffeners 11 in the example shown—which support the belt receptacles 4a and 4b. The first belt receptacle 4a is formed by the circular cutouts in the stiffeners 11. The stiffeners 11 also have several cutouts along their entire length, which primarily serve to reduce weight.

[0043] Fig. 3 and Fig. 4 show the seat-mounted state of the adapter 1, which was attached to the vehicle seat S as described above. The vehicle belt 5 is a standard three-point safety belt, and the adapter was mounted on the passenger seat, which is preferred. The lap belt section 5a is received by the first belt receptacle 4a (see Fig. 3) and the chest strap section 5b is taken up by the second strap holder 4b (see Fig. 4). The seat plate 10 has a projection 12 at its end facing the seat back S1, which is inserted into the gap between the seat back S1 and the seat surface S2 (see Fig. 5).

[0044] The preferred sequence for mounting the adapter 1 on the seat S is as follows: First, the support bracket 6 should be pressed against the seat back S1 and the projection 12 inserted into the aforementioned slot. The seat should then be moved completely rearward to facilitate installation of the vehicle belt 5. The lap belt section 5a can then be threaded into the first belt receptacle 4a and pulled through it. The buckle tongue can then be engaged in the belt buckle. In the next step, the chest belt section 5b is preferably pulled around the second belt receptacle 4b and routed to the front. Pre-tensioning can also be achieved by firmly pulling on the vehicle belt 5.

[0045] In Fig. 1 are also mushroom tours 9 (see also Fig. 8). Here, the mushroom guide 9 is preferably mounted below the holding plate 2 (pointing in the direction of the seat plate 10) and preferably has the same radius as the radius of the corresponding largest hole in the fastening device 3. This mushroom guide 9 serves as a simple centering stop when removing or undocking the adapter plate 13 described above.

[0046] The fastening devices 3 in the holding plate preferably comprise a circular hole, which is adjoined by a slotted hole of smaller diameter, which runs in the direction of the side facing away from the seat back. The slotted hole preferably runs parallel to the long side of the adapter 1 and is preferably perpendicular to the transverse side of the adapter 1. These fastening devices 3 can thus be used in a simple manner for many fastening options. It is preferred that an equivalent adapter plate 13 (see Fig. 9 and Fig. 10) with attached objects is prepared in the laboratory or outside the vehicle. For this purpose, the adapter plate 13 preferably has a plurality of holes that can be used to attach a wide variety of objects.

[0047] This adapter plate 13 preferably has mushroom-shaped projections 14 on its underside, which can be inserted into the circular holes of the fastening devices 3. Accordingly, the mushroom-shaped projections 14 must be distributed equivalently to the fastening devices 3 in the holding plate 2. The underside of the adapter plate 13 then preferably rests on the upper side of the holding plate 2 or is spaced from it by spacers 15, and the slender part of the mushroom-shaped projections 14 can be guided in the elongated holes to their closed end, whereby the adapter plate 13 is held in the fastening devices 3 on the holding plate.

[0048] As mentioned above, it is preferred if the circular hole is at least partially reinforced in its peripheral area by a mushroom guide 9, which is mounted on the underside of the holding plate 2. This mushroom guide 9 serves as a simple centering stop when removing or undocking the adapter plate 1 described above.
