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, measuring equipment typically needs to be transported on board the vehicle for test drives. Very often, this equipment is located inside the vehicle to allow access during the test drive. To prevent the equipment from shifting during the journey, it is secured with straps.

[0003] Securing the equipment with lashing straps is a relatively lengthy process and must be carried out with the utmost care to ensure the measuring equipment remains securely attached to the vehicle while driving. A problem arises from the fact that lashing points are not located everywhere on the vehicle, meaning that securing the equipment may only be possible under difficult conditions. STATE OF THE ART

[0004] A first possibility 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 mounting the measuring equipment described in this document also has certain weaknesses. In particular, attaching and detaching the adapter from a bracket in the vehicle is cumbersome and difficult. OBJECT OF THE INVENTION

[0005] Against this background, the object of the invention is to provide an adapter for a motor vehicle which quickly and easily connects objects connected to the adapter, such as measuring technology, to 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 a motor vehicle is proposed, comprising a mounting plate, wherein two locking devices are arranged on the mounting plate for locking the adapter to a bracket attached to the motor vehicle. These locking devices preferably interact with the bracket in question in such a way that they lock with the bracket. It is preferred that two Isofix brackets are used as the bracket, which are preferably mounted as standard on or on the rear seats of the motor vehicle.

[0008] The mounting plate is equipped with at least one fastening device for attaching an object to the adapter. The object is preferably a component of the measuring equipment to be attached or a related component such as special brackets. The adapter comprises, in particular, two parallel locking arms, with one locking device located at each end of the locking arms. The locking arms are guided and interact with a locking mechanism in such a way that the locking arms can be moved relative to the mounting plate in and against a sliding direction as long as the locking mechanism is not engaged. Conversely, the locking arms are fixed and therefore cannot be moved when the locking mechanism is engaged.

[0009] According to the invention, the adapter is characterized in that each locking arm comprises a Bowden cable mechanism with which the locking mechanism can be released. When the locking mechanism is released, it is in the aforementioned unactivated position. The Bowden cable mechanism comprises at least one core (or inner cable), preferably made of steel wire, and a flexible, but compression-resistant sheath in the direction of tension, in which the core is routed. The sheath (or sleeve) serves to guide the core and as a possible support point for a counter bearing to support the tensile forces to be transmitted. The Bowden cable can thus transmit tensile forces along virtually any curved path, resulting in a quick and easy way to release the locking mechanism and, preferably, to mount and / or dismount the adapter. PREFERRED TRAINING OPPORTUNITIES FOR THE INVENTION

[0010] A preferred embodiment of the adapter consists of a ratchet mechanism which, when activated, allows the locking arms to be moved relative to the mounting plate, preferably telescopically, such that the end face of the mounting plate directly opposite a rear seat backrest of the vehicle is brought closer to the backrest or even compresses its upholstery locally, whereupon the affected locking arm is preferably automatically locked in this position. This makes it easy to adjust and lock the position of the mounting plate and thus of the objects attached to it. It is particularly advantageous if the objects (such as measuring instruments) on the mounting plate or an auxiliary support connected to the mounting plate are positioned as close as possible to the backrest when the vehicle is ready for driving.In this way, particularly good fixation is achieved even when cornering, and the most accurate possible measurement data can be determined.

[0011] Furthermore, it is particularly preferred if the locking mechanism is a ratchet mechanism, a pawl lock or other self-locking mechanism that allows the retaining plate to be pushed ever closer to the back of the seat or that compresses it ever more strongly, but prevents the retaining plate from moving from a locked position once reached in the opposite direction, away from the back of the seat - unless the Bowden cable mechanism is actuated.

[0012] It is particularly advantageous if the locking mechanism is designed in such a way that it allows the following energy-saving alternating movement or the following procedure: The locking fingers of the locking device are positively connected to their respective holders on the vehicle. The locking arms are then moved together relative to the holding plate so that the holding plate or its auxiliary support or the measuring devices or other payload on the holding plate rests against the rear seat backrest or its upholstery. Bracing is now achieved with the rear seat backrest using an alternating feed: First, in step 1, one locking arm is moved at least one notch, where it then engages, so that the holding plate or its auxiliary support or the measuring devices on its side rest even more closely against the rear seat backrest or compress its upholstery (or compress it even more). The same process is then repeated as step 2 for the locking arm on the other side. If necessary, steps 1 and 2 are repeated again or even several times. This means that the locking process can be carried out with significantly less force or effort.Maximum force per step achieves a very close contact with the backrest or a very strong tension against its padding - which would often not be possible if one had to compress the padding of the backrest across its entire width in a single step.

[0013] Furthermore, it is particularly advantageous if the adapter includes a support bracket to prevent rotation around the mount, and especially if the support bracket includes a handle for holding the adapter. This provides a second point of fixation, in addition to securing the adapter to the mount, which prevents rotation of the adapter around the mount. The handle also facilitates the installation and removal of the adapter in the vehicle.

[0014] Furthermore, it is particularly preferred if the adapter includes a seat plate that is firmly connected to the mounting plate at a distance from the mounting plate, with the seat plate being designed for placing the adapter on the vehicle seat. This provides a flat contact surface for the adapter on the vehicle seat, allowing the weight to be distributed more easily across the seat.

[0015] Another preferred embodiment of the adapter consists in the connection of an object to the fastening device being detachable and, in particular, being a screw connection, a clamping device, or a bayonet connection. Thus, the adapter can be easily fitted with various objects.

[0016] Furthermore, it is particularly preferred if the adapter has at least one thumb release with which at least one Bowden cable mechanism can be actuated. Preferably, one thumb release can actuate either one Bowden cable mechanism at a time, or, although this is not preferred, two Bowden cable mechanisms. The thumb release is preferably a component that can only be moved, preferably partially rotated, by actuation with a thumb in such a way as to actuate the Bowden cable mechanism. In this way, the locking mechanism can be released easily with minimal effort and by actuating a separate component.

[0017] Furthermore, it is particularly preferred if the adapter has a counter-support near each of the at least one thumb opener, which holds back the sleeve of the Bowden cable mechanism. The counter-support (or counter bearing) mentioned above is required for the intended operation of a Bowden cable mechanism in order to support the tensile forces to be transmitted. "Near" the thumb opener means that the counter-support is located at most 20 cm away from the nearest point of the thumb opener, preferably at most 10 cm, and most preferably at most 5 cm.

[0018] Another preferred embodiment consists in the adapter preferably having a stiffener on each of its two longitudinal sides, acting as a spacer between the seat plate and the mounting plate. This allows for a simple and effective way to ensure both the distance between the two plates and to provide additional stiffening and stabilization of the adapter.

[0019] Furthermore, it is particularly preferred if the adapter has at least one, preferably two, belt guides that serve as guides for a vehicle seat belt. This allows a standard vehicle seat belt to be easily used to further secure the adapter in its mounted state. For this purpose, the belt guides are preferably designed to guide the vehicle seat belt around the adapter and at least partially hold it in position to prevent the belt from slipping off the adapter.

[0020] Furthermore, it is particularly preferred if the locking device comprises at least two foldable teeth, which preferably protrude from the locking arm on the side facing the holding plate, wherein the teeth are offset from one another in the width direction. The width direction is the direction which is perpendicular to the direction in which the locking arm can be pushed together and which faces the underside of the holding plate, preferably even touches it. In this case, a first tooth can penetrate an opening assigned to it in the corresponding side of the covering of the locking arm, wherein this first tooth can be folded in by actuating the Bowden cable mechanism. The “covering” of the locking arm is only the outermost layer of the locking arm.The "folding in" of the first tooth can either occur actively, by the tooth actively folding downwards by actuating the Bowden cable, or passively, by the first tooth being released to fold away, whereby additional force is required in order to then finally fold the tooth in. In addition, the second tooth can penetrate several of its associated openings in the corresponding side of the locking arm cover, whereby this second tooth is folded in by the telescopic displacement of the locking arm as material moves over it and the telescopic movement blocks it in one direction after snapping into an opening. The second tooth is "automatically" folded in during the telescopic displacement of the locking arm when the telescopic movement moves the tooth into an area in which it is folded down by the material above it.Preferably, the first tooth and / or the second tooth also comprises a resilient mechanism, which gives the respective tooth a tendency to protrude upwards—through the side facing the retaining plate. This generally provides a simple locking mechanism that allows for easy and convenient operation for mounting and dismounting the adapter.

[0021] Furthermore, it is particularly preferred if the locking device is designed such that in the respective extreme position of the second tooth—and thus either at the very back or at the very front, i.e., with the locking arm fully retracted or fully extended—the first tooth must first be folded in using the Bowden cable mechanism to allow a telescopic displacement of the locking arm. In this case, folding in is either an active folding or a release of the tooth for possible folding. In this way, a safety mechanism is created in a simple manner to prevent the locking arm from being accidentally extended or retracted.

[0022] Furthermore, it is particularly advantageous if the locking mechanism is designed such that the second tooth does not engage in one of its associated openings when the locking arm undergoes a telescoping movement – ​​at least when installed on the mounting plate. This allows the locking arm to be fully extended without having to pass through each opening individually. While during retraction (the telescoping movement), a single pass and engagement of the second tooth in its respective opening is even preferred – as mentioned above – during extension, a quick and smooth operation is desirable, which is easily achieved with this design.

[0023] Another preferred embodiment consists in the locking device comprising a rotatable mounting receptacle having an upper and a lower locking finger, wherein the upper and lower locking fingers partially engage the mounting, and wherein, upon insertion of the mounting and rotation of the mounting receptacle by 90 degrees, the mounting receptacle locks into place such that the upper locking finger obscures direct access to the mounting and the mounting receptacle can no longer be released as intended, unless the Bowden cable mechanism is actuated. This provides an additional layer of security against unintentional decoupling of the adapter from the mounting.

[0024] 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. ANOTHER TASK UNDERLYING THE INVENTION

[0025] Furthermore, the invention is based on the objective 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

[0026] A solution to this problem is provided by claim 21.

[0027] Herein a system is proposed which comprises the adapter according to the invention, an adapter plate, preferably a support, an additional adapter for attachment to the passenger seat of the vehicle and a mounting plate for installation in the trunk of the vehicle.

[0028] The adapter for mounting on the passenger seat is described in the unpublished application 20 2024 103 584.4, which is fully incorporated into this disclosure. The corresponding application is submitted as an additional document alongside this application.

[0029] The mounting plate for installation in the vehicle's trunk is described in the unpublished application 20 2024 001 249.2, which is fully incorporated into this disclosure. The corresponding application is submitted as an additional document alongside this application.

[0030] The system according to the invention is characterized in that the measuring technology and / or components related to 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 in the correspondingly cooperating mounting devices, wherein the adapter plate can be mounted in the same manner on the mounting plate of the adapter according to the invention on the rear seat, or on the adapter of the passenger seat, or on the mounting plate in the trunk.

[0031] This allows for the simple creation of a flexible mounting system, enabling the measuring equipment and related components to be mounted on an adapter plate outside the vehicle, preferably even in the laboratory. Ideally, an adapter is already mounted on the passenger seat, at least one adapter is on one of the rear seats, and / or a mounting plate is installed in the trunk. Depending on the test situation, the user can then flexibly choose which of these mounting points the adapter plate should be attached to. Furthermore, mounting and dismounting the adapter plate is very quick and easy, preferably without tools, simply by placing and sliding the adapter plate.

[0032] 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.

[0033] The Fig. 1 to Fig. Figure 3 shows the assembled adapter 1 with its individual parts. The basic structure of the adapter 1 consists of the mounting plate 2 and the seat plate 10, which are mounted at a distance from each other. The spacer between the two plates is preferably a stiffener 13 on both sides, which is attached to the longitudinal sides of the plates. The stiffener 13 (see Fig. 7) is preferably located in its entirety between the retaining plate 2 and the seat plate 10. Preferably, the stiffening 13 consists of two parts that surround the locking arm 5 and are preferably even designed as a receptacle for the locking arm 5.

[0034] The retaining plate 2 (see Fig. 4) is the upper of the two plates and comprises various fastening devices 4 for fastening objects or fastening devices for objects. Preferably, a mushroom guide 15 is connected to each of the fastening devices 4, preferably in the area of ​​the radius. This mushroom guide (see Fig. 5) preferably serves as a guide for cylindrical components that are inserted into the fastening device 4 and is preferably located on the half of the largest bore of the fastening device 4 facing the support bracket 8. Here, the mushroom guide 15 is preferably attached 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 bore of the fastening device 4.

[0035] At the rear end of the holding plate 2 (the end facing the locking arms 5), the adapter 1 comprises a support bracket 8 with a handle 9 (see Fig. 8). The support bracket 8 is preferably a curved tube construction, wherein its two open ends are preferably each supported by a support bracket holder 16 (see Fig. 6) are included. This support bracket holder 16 is preferably mounted between the mounting plate 2 and the seat plate 10. The support bracket 8 has several holes at its two free ends. These can be used to adjust the position of the support bracket 8. This allows the support bracket 8 to be mounted closer to or further away from the mounting plate 2.

[0036] Two locking arms 5 are preferably mounted on the mounting plate 2, which are also partially located between the mounting plate 2 and the seat plate 10. At the end of the locking arm 5 facing the support bracket 8, it includes a locking device 3 for attachment to a mounting bracket of a motor vehicle. The locking arm 5 is designed to be slidable or telescopic and has a sliding direction V for retraction and extension. The locking arm 5 also includes a ratchet mechanism 7 with various openings for preferably a first tooth and a second tooth (not shown here).

[0037] At the end facing away from the support bracket 8, a part of the Bowden cable mechanism 6 leaves the locking arm and interacts with the ratchet mechanism 7. At the free end of the Bowden cable mechanism 6, the core protrudes from the sleeve, with the free end of the core preferably having a projection. This projection at the free end of the core can be used by a thumb opener 11 (see Fig. 9) are included. Preferably, two thumb openers 11 are attached to the adapter 1, which are also located at least partially between the retaining plate 2 and the seat plate 10, with each thumb opener 11 preferably actuating a Bowden cable mechanism 6. The thumb openers 11 are preferably each attached to the lower end (facing away from the support bracket 8) of the longitudinal side of the retaining plate 2 and are preferably at least partially rotatable about the axis A of the bore of the thumb opener 11. In order to enable the rotational movement to be carried out as intended, sliding bushings 17 are preferably inserted into the bore of the thumb opener 11 on both sides.

[0038] In order to transmit the tensile force of the Bowden cable mechanism 6, a counterholder 12 is preferably located between the locking arm 5 and the thumb opener 11 (see Fig. 11). This counterholder 12 receives the end of the sleeve of the Bowden cable mechanism 6, whereby the core can be moved while supporting the sleeve of the Bowden cable mechanism 6. The counterholder 12 preferably consists of two parts mounted one above the other, which in Fig. 11. These two parts are preferably held together by two pins and are also completely mounted between the retaining plate and the seat plate 10.

[0039] Preferably in the area of ​​the rear corners (on the short side of the holding plate 2 facing away from the support bracket 8) there is preferably a belt holder 14. This belt holder 14 (see Fig. 10) preferably has a guide 18 for a motor vehicle belt on both sides.

[0040] The fastening devices 4 in the mounting plate preferably comprise a circular hole to which a smaller-diameter elongated hole is connected, extending towards the side of the seat facing away from the seat back. Preferably, the elongated hole runs parallel to the longitudinal side of the adapter 1 and is preferably perpendicular to the transverse side of the adapter 1. These fastening devices 4 can thus be used easily for many fastening applications. It is preferred that an equivalent adapter plate 19 (see Fig. 12) with attached objects already prepared in the laboratory or outside the vehicle. For this purpose, the adapter plate 19 preferably has a large number of holes which can be used to attach a wide variety of objects.

[0041] This adapter plate preferably has mushroom-shaped projections 20 on its underside, which can be inserted into the circular holes of the fastening devices 4. Accordingly, the mushroom-shaped projections must be distributed in the mounting plate 2 in a manner equivalent to the fastening devices 4. The underside of the adapter plate 19 then preferably rests on the top side of the mounting plate 2 or is spaced from it by spacers 21, and the slender part of the mushroom-shaped projections can be guided to their closed end in the elongated holes, thereby holding the adapter plate 19 in the fastening devices 4 on the mounting plate.

[0042] As mentioned above, it is preferred if the circular hole is at least partially reinforced in its circumferential area by a mushroom guide 15, which is attached to the underside of the retaining plate 2. This mushroom guide 15 serves as a simple centering stop when removing or undocking the adapter plate 1 described above.

[0043] Furthermore, the figures show Fig. 14 and Fig. 15 a support 22 (see Fig. 15) and their preferred mounting position relative to adapter 1 (see Fig. 14). The support 22 serves to support the motor vehicle belt in the chest belt area. As a result, the belt does not just rest on the seat in this area or is even loose in the air, but rather it rests at least partially on the support 22 in the chest belt area. The support 22 is preferably designed as a pad or cushion which comprises at least one loop 23 at its upper end facing the headrest. This loop is attached around the headrest of the respective seat as additional security and protection against slipping when the adapter 1 is mounted. The pad or cushion preferably comprises a Styrofoam core which virtually simulates a human chest, whereby the motor vehicle belt fits better. As a result, the adapter 1 can withstand even greater loads and is also even better secured.

[0044] Fig.Figure 14 shows the preferred positioning of the support 22, which preferably rests on the support bracket 8. The dimensions of the support 22 can vary, but are preferably in the range of a height of approximately 440 mm, a width of approximately 270 mm and a depth of approximately 100 mm. MISCELLANEOUS

[0045] In due course, if necessary, protection will also be claimed for a design that stands alone or is in combination with other claims already made and / or with one or more individual features from the description, as follows: Adapter 1 for securing measuring and / or data processing devices in the passenger compartment of a motor vehicle in a manner that protects occupants from avoidable injuries in the event of a crash, preferably with several sliding locking arms 5 for locking the adapter 1 to one or more Isofix mounting brackets, characterized in that the at least one locking arm 5 comprises a Bowden cable mechanism 6 with which the locking arm can be released.
