Description

Field of the Invention

[0001] The present invention relates to a base, a mirror leg, and a mounting assembly for mounting an interior rearview mirror of a vehicle. Background Art

[0002] In vehicle manufacturing, an interior rearview mirror is usually mounted on the windshield in the interior space of the vehicle. A known mounting assembly herein includes a base mounted on the windshield. A mirror leg is mounted on the base, and when installing, the mirror leg is screwed onto the base. In the final installation position, the base and the mirror leg abut against each other and are held together by a torsion spring. Finally, the interior rearview mirror is provided on the mirror leg.

[0003] For example, it is known from DE 21 2018 000 374 U1 that four positioning slots of a holding device are embedded in four positioning mechanisms on a windshield button, and the holding device and the windshield button are held together by a fixing clip. The windshield button is also provided for accommodating a sensor.

[0004] Furthermore, in DE 11 2019 000 611 T5, five mating protrusions of five protrusions of a support base and mating grooves in a support surface of a mounting base abut against each other and are pressed against each other by the pre-tightening force of an arm of a leaf spring for mounting the support base. Thus, five abutting support sections are formed. A sensor assembly is also provided between the support base and the mounting base.

[0005] However, the disadvantage of the known mounting assemblies is that they have a complex structure and thus require a large space requirement. In addition, undesired vibrations occur in the mounting assembly during vehicle driving operation, and the known mounting assemblies cannot prevent such vibrations. Summary of the Invention

[0006] Therefore, the task on which the present invention is based is to provide a base for mounting an interior rearview mirror of a vehicle that has low vibrations and saves space, a corresponding mirror leg, and a corresponding mounting assembly.

[0007] The solution according to the invention for this task is achieved by a base for being provided on a windshield of a vehicle and for accommodating a mirror leg of an interior rearview mirror.

[0008] The present invention relates to a base for being arranged on a windshield of a vehicle and for receiving a foot of an interior rearview mirror, the base having a base plane. According to the invention, at least six resistance surfaces are arranged on the base plane; every two resistance surfaces are at least partially arranged in a common resistance plane, thereby forming at least three resistance planes; each of the resistance planes in the resistance planes is oriented relative to the base plane such that the resistance plane intersects the base plane in a straight line, thereby forming at least three straight lines in the base plane, and the straight lines have intersection points with an acute intersection angle at least pairwise between each other, thereby forming at least three acute intersection angles, the intersection points are arranged between the resistance surfaces of the intersecting straight lines, and the acute intersection angles are equal.

[0009] Due to the equal acute intersection angles, the base can transmit the forces occurring during the driving operation of the vehicle in a uniformly distributed manner, thereby minimizing vibrations to the greatest extent. Therefore, the base can symmetrically absorb or transmit these forces. In addition, the resistance surfaces can particularly well absorb or transmit the occurring forces through their planar design and can be constructed more space-savingly compared to the engaging elements. Here, the term "equal acute intersection angles" is generally understood to mean that the acute intersection angles are substantially equal and the difference is only within a tolerance range of ±3°.

[0010] Preferably, six resistance surfaces are arranged on the base plane here and the acute intersection angles are each 60°. The forces can be particularly well absorbed with six resistance surfaces and acute intersection angles of 60° each. Here, a resistance surface corresponds to half a fulcrum of a static system, and the static system is in turn statically completely defined by three complete fulcrums. Therefore, overdefinition is avoided with six resistance surfaces, which further saves space. Generally speaking, in the mechanical sense, a resistance surface can be understood as half a fulcrum. The stable orientation in space can be defined by three fulcrums.

[0011] In a preferred embodiment, two resistance surfaces are at least partially arranged in a common resistance plane such that in the mounted state of the base in the vehicle, the resistance surfaces are arranged for absorbing the collision forces caused by a collision in the X direction of the vehicle. The collision forces may be caused, for example, by the forward-accelerating head of a vehicle occupant. Therefore, the collision forces in the X direction of the vehicle can be particularly well absorbed by the base until a certain threshold. The two resistance surfaces are arranged such that when the collision force exceeds the threshold, the foot of the mirror separates from the base, thereby preventing head injuries. The collision forces are generally defined in the regulation FMVSS 571.111.

[0012] To limit the detachment of the temple from the base, the temple is preferably connected to the base by a restraint strap. In one embodiment, the base accordingly has a side wall in which through-holes are provided for receiving clips for the restraint strap. The clips are here connected to the restraint strap and inserted into the through-holes.

[0013] In one embodiment, a fitting region for fitting with a planar torsion spring is constructed on the side wall. Thereby, the temple can be advantageously fixed to the base by means of the torsion spring.

[0014] Particularly preferably, the fitting region includes a fixing element protruding from the side wall for fitting with the torsion spring and at least two notches, and for each notch on the side wall, a pre-fixing rib for fitting with the torsion spring is provided. Before the temple is rotated to its final installation position, the temple can be pre-fixed to the pre-fixing rib by means of the torsion spring during installation. Thereby, a simplified installation with higher safety is provided, since the temple can be pre-fixed to the base in a first-hand position and can be comfortably rotated to the final installation position in a second-hand position, where the second-hand position is more suitable for rotation. Thus, dropping of the temple is avoided when changing from the first-hand position to the second-hand position.

[0015] In all embodiments, preferably the angle between the base plane and the respective resistance plane is less than 90° and preferably in the range of 25° to 45°, particularly preferably in the range of 30° to 45°. Thus, with respect to the collision force in the vehicle X, Y or Z direction, the threshold value for the detachment of the temple from the base can be set particularly advantageously.

[0016] The invention also relates to a temple for connecting to a base and for arranging an interior rearview mirror on the windshield of a motor vehicle, the temple having a temple plane. According to the invention, at least six fixing surfaces are provided on the temple plane; two fixing surfaces each are at least partially arranged in a common fixing plane, thereby forming at least three fixing planes; each of the fixing planes is oriented relative to the temple plane such that the fixing plane intersects the temple plane in a straight line, thereby forming at least three straight lines in the temple plane, the straight lines having intersections with an acute angle between them at least in pairs, thereby forming at least three acute-angle intersections, the intersections being arranged between the fixing surfaces belonging to the intersecting straight lines and the acute-angle intersections being equal.

[0017] Due to the equal acute intersection angles, the temple can evenly distribute and transfer the forces that occur during the running of the vehicle, thereby minimizing vibrations to the greatest extent. Therefore, the temples can symmetrically absorb or transfer these forces. In addition, the fixing surface can particularly well absorb or transfer the occurring forces through its planar design and can be constructed more space-savingly compared to the fitting elements. Here, the term "equal acute intersection angles" is generally understood to mean that the acute intersection angles are substantially equal and the difference is only within a tolerance range of ±3°.

[0018] The invention further relates to a mounting assembly for mounting an interior rearview mirror of a vehicle, the mounting assembly including a base according to one of the foregoing embodiments and temples according to the foregoing embodiments. In the final mounting state, the base and the temples are connected to each other such that a resistance surface and a fixing surface are in contact with each other.

[0019] Since the acute intersection angles are equal not only in the base but also in the temples, the mounting assembly can evenly distribute and transfer the forces that occur during the running of the vehicle, thereby minimizing vibrations to the greatest extent. Therefore, the paired resistance surfaces and fixing surfaces that are in contact with each other in a plane can symmetrically absorb or transfer these forces. In addition, the resistance surfaces and the fixing surfaces can particularly well absorb or transfer the occurring forces through their planar design and can be constructed more space-savingly compared to the fitting elements.

[0020] According to a preferred embodiment, the mounting assembly includes a sensor for being arranged on the windshield of the vehicle. In the final mounting state, the sensor and the base connected to the temples are arranged at different positions on the windshield, preferably side by side. Since the base according to the invention is constructed particularly space-savingly as described above, the base is advantageously arranged beside the sensor on the windshield, thereby enabling a more flat design of the base and the sensor in the interior space. Therefore, according to the invention, the sensor is not arranged inside the base.

[0021] Preferably, the mounting assembly may also include the windshield of the vehicle.

[0022] In addition, a vehicle is provided, which has a base according to one of the foregoing embodiments, temples according to the foregoing embodiments, or a mounting assembly according to one of the foregoing embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 Schematic perspective view showing an embodiment of a base 10 according to the present invention, which is adapted to be arranged on a windshield of a vehicle and to accommodate Figure 2 the mirror leg 20 for an interior rearview mirror therein. The base 10 is preferably configured to be circular.

[0030] Here, the base 10 preferably extends at least partially in the base plane 12. As shown Figure 1 herein, the base plane 12 can be formed by the surface of the base. However, it is also conceivable that the base plane 12 is only defined by an abstract plane. Preferably, each part of the base 10 extends into this plane or at least intersects this plane.

[0031] Six resistance surfaces 14.1 - 14.6 are provided on the base plane 12. Here, the resistance surfaces 14.1 and 14.2, as a first pair of resistance surfaces, are at least partially arranged in a common resistance plane E1. For example, the edge regions of the resistance surfaces 14.1 and 14.2 can also deviate from the plane E1.

[0032] As can be seen in Figure 4 herein, the resistance plane E1 is arranged at an angle β with respect to the base plane 12 and the plane E1 thus intersects the base plane 12 in a straight line G1. For the sake of clarity, the angle β is not shown in Figure 1 herein. Preferably, the angle β is less than 90° and preferably in the range of 25° to 45°, particularly preferably in the range of 30° to 45°.

[0033] In the same way as the first pair of resistance surfaces, the second pair of resistance surfaces 14.3 and 14.4 and the third pair of resistance surfaces 14.5 and 14.6 are arranged in a plane E2 or E3 at an angle β with respect to the base plane 12, thereby forming straight lines G2 and G3. Here, the angle β can be selected to be the same or different for each of the planes E1, E2, and E3.

[0034] The resistance surfaces 14.1 - 14.6 are arranged on the base plane 12 in such a way that the resulting straight lines G1 - G3 have intersection points S1 - S3 with an acute intersection angle α at least pairwise. The intersection point S1 is formed, for example, by the intersecting straight lines G1 and G3 and is arranged here between the resistance surfaces 14.1 and 14.2 as well as 14.5 and 14.6. In addition, the intersection point S2 is formed, for example, by the intersecting straight lines G2 and G3 and is arranged here between the resistance surfaces 14.3 and 14.4 as well as 14.5 and 14.6. Finally, the intersection point S3 is formed, for example, by the intersecting straight lines G1 and G2 and is arranged here between the resistance surfaces 14.1 and 14.2 as well as 14.3 and 14.4.

[0035] As can be seen in Figure 1 three equal acute intersection angles α are formed between the straight lines G1 and G2, G2 and G3, and G1 and G3. In the preferred case of three pairs of resistance surfaces, the acute intersection angle α is always 60°.

[0036] The equal acute intersection angle α ensures that the forces occurring during the driving operation of the vehicle are transmitted evenly through the resistance surfaces 14.1 - 14.6 of the base 10. The resistance surfaces 14.1 - 14.6 can absorb or transmit the occurring forces particularly well due to their planar design and can be constructed more space - saving compared to the mating elements. Thus, the vibrations during the driving operation are minimized.

[0037] It can also be considered here that the base 10 has more than three pairs of resistance surfaces and the resulting acute intersection angle α is always equal to ensure a symmetrical force distribution. As mentioned at the beginning, a tolerance range of ±3° is also considered here.

[0038] In addition, it can also be considered that the resistance surfaces 14.1 - 14.6 are arranged in such a way that the resulting straight lines G1 - G3 all intersect at a common intersection point S (not shown). When the resistance surfaces 14.1 - 14.6 are arranged in a circular shape as Figure 2 shown, the spacing of the individual resistance surfaces 14.1 - 14.6 on the circumference line is thereby increased, which constitutes an alternative arrangement for uniform force transmission when the acute intersection angle α is equal.

[0039] Preferably, one pair of resistance surfaces is assigned to the X - direction of the vehicle, and in Figure 1 this can be, for example, the resistance surfaces 14.5 and 14.6.

[0040] In the mounted state of the base in the vehicle, the resistance surfaces 14.5 and 14.6 are provided for absorbing the collision forces caused by a collision in the X direction of the vehicle. The collision forces may, for example, be caused by the head of a vehicle occupant accelerating forward and hitting the rearview mirror in the vehicle. Thus, the collision forces in the X direction of the vehicle can be absorbed particularly well by the base 10 up to a certain threshold. The two resistance surfaces 14.5 and 14.6 are arranged here by selecting the angle β such that when the collision force exceeds the threshold, the mirror foot 20 with the rearview mirror separates from the base 10, thereby avoiding head injuries.

[0041] Likewise, the paired resistance surfaces 14.1 and 14.2 and 14.3 and 14.4 can be assigned to the Y direction of the vehicle so that when a collision force occurs in the Y direction of the vehicle, the mirror foot 20 with the rearview mirror can be detached from the base 10 in the same way. Here, the force can act and be absorbed in the XY plane.

[0042] Furthermore, as can be seen in Figure 1 a through hole 16.1 is constructed in the side wall 16 of the base 10. A clip 30 can be inserted through the through hole 16.1, and the movement of the clip is restricted by at least one restricting element 16.2 within the base 10. The clip 30 is constructed such that the flexible element of the clip 30 engages with the base 10 in the locking position on the restricting element 16.2. A restraining strap (not shown) is fixed to one end of the clip, and the restraining strap is in turn fixed to the mirror foot 20. When a collision occurs in the vehicle, the mirror foot 20 with the rearview mirror separates from the base 10 and the movement of the mirror foot can be restricted by means of the restraining strap.

[0043] Figure 2 Fig. shows a schematic perspective view of an embodiment of the mirror foot 20 according to the invention, which is for connection to the base 10 and for arranging the rearview mirror on the windshield of a motor vehicle. The mirror foot 20 is a mating part for the base 10 and has a plane, straight lines and intersection angles corresponding to those of the base 10.

[0044] Here, the mirror foot 20 preferably extends at least partially in the mirror foot plane 22. Here, as Figure 2 shown, the mirror foot plane 22 can be formed by the surface of the mirror foot 20. However, it is also conceivable that the mirror foot plane 22 is only defined by an abstract plane. Preferably, the various parts of the mirror foot 20 extend into or at least intersect this plane.

[0045] Six fixing surfaces 24.1 - 24.6 are provided on the mirror foot plane 22. Here, the fixing surfaces 24.1 and 24.2, as the first pair of fixing surfaces, are at least partially arranged in a common fixing plane F3. For example, the edge regions of the fixing surfaces 24.1 and 24.2 can also depart from the plane F3.

[0046] Contrary to the base 10, inFigure 2 The middle fixing surfaces 24.1 - 24.6 extend from the temple plane 22 towards the rest of the temple 20's body, while in Figure 1 the base 10 in , the resistance surfaces 14.1 - 14.6 extend from the base plane 12 away from the rest of the base 10's body. Thus, the resistance surfaces 14.1 - 14.6 and the fixing surfaces 24.1 - 24.6 can abut against each other according to the key - lock principle in the installed state as Figure 3 shown.

[0047] Therefore, all the advantageous features of the base 10 equally apply to the temple 20 and can be transferred to the temple:

[0048] As can also be seen in Figure 2 , exemplarily, the fixing plane F1 is set at a right - angle β' relative to the temple plane 22 and the plane F1 thus intersects the temple plane 22 in a straight line G1'. The preferred angle β' is less than 90° and preferably in the range of 25° to 45°, particularly preferably in the range of 30° to 45°.

[0049] In the same way as the first pair of fixing surfaces, the second pair of fixing surfaces 24.3 and 24.4 and the third pair of fixing surfaces 24.5 and 24.6 are set in the plane F2 or F1 (the angle β' of these pairs is not shown) at an angle β' to the temple plane 22, thereby forming straight lines G2' and G3'. Here, β' can be selected the same or differently for each of the planes F1, F2, and F3. Preferably, β' = β is selected respectively so that the resistance surfaces 14.1 - 14.6 and the fixing surfaces 24.1 - 24.6 abut against each other better as Figure 3 shown.

[0050] The fixing surfaces 24.1 - 24.6 are set on the temple plane 22 such that the resulting straight lines G1' - G3' have intersection points S1' - S3' with an acute - angle α between them at least in pairs. The intersection point S1' is formed, for example, by the intersecting straight lines G1' and G2' and is set here between the fixing surfaces 24.5 and 24.6 and 24.3 and 24.4. In addition, for example, the intersection point S2' is formed by the intersecting straight lines G2' and G3' and is set here between the fixing surfaces 24.3 and 24.4 and 24.1 and 24.2. Finally, for example, the intersection point S3' is formed by the intersecting straight lines G1' and G3' and is set here between the fixing surfaces 24.1 and 24.2 and 24.5 and 24.6.

[0051] As can be seen in Figure 2 , three equal acute - angle intersections α are thus formed between the straight lines G1' and G2', G2' and G3', and G1' and G3'. In the preferred case of three pairs of fixing surfaces, the acute - angle intersection α is always 60°.

[0052] Ensure the uniform distribution of the forces occurring during vehicle driving operation through the fixing surfaces 24.1 - 24.6 of the temple 20 by equal acute intersection angles α. The fixing surfaces 24.1 - 24.6 can particularly well absorb or transmit the occurring forces through their planar design and can be constructed more space - saving compared to the mating elements. Thus, the vibrations during driving operation are minimized to the greatest extent.

[0053] It can also be considered here that the temple 20 has more than three pairs of fixing surfaces, and the resulting acute intersection angles α are always equal to ensure a symmetric force distribution. As mentioned at the beginning, a tolerance range of ±3° is also considered here.

[0054] In addition, it can also be considered that the fixing surfaces 24.1 - 24.6 are arranged such that the resulting straight lines G1' - G3' all intersect at a common intersection point S (not shown). When the fixing surfaces 24.1 - 24.6 are arranged in a circular shape as Figure 2 shown, the spacing of the fixing surfaces 24.1 - 24.6 on the circumferential line is thereby increased, which constitutes an alternative arrangement for uniform force transmission when the acute intersection angles α are equal.

[0055] Preferably, a pair of fixing surfaces is assigned to the X - direction of the vehicle. In Figure 1 this, for example, these can be the fixing surfaces 24.5 and 24.6.

[0056] In the installation state of the base in the vehicle, the fixing surfaces 24.5 and 24.6 are arranged to absorb the collision forces caused by a collision in the X - direction of the vehicle. The collision forces can be caused, for example, by the forward - accelerating head of a vehicle occupant hitting the interior rear - view mirror in the vehicle. Thus, the collision forces in the X - direction of the vehicle can be particularly well absorbed by the temple 20 up to a certain threshold. These two fixing surfaces 24.5 and 24.6 are arranged here by selecting the angle β' such that when the collision force exceeds the threshold, the temple 20 with the interior rear - view mirror is separated from the base 10, thereby avoiding head injuries.

[0057] Similarly, the paired fixing surfaces 24.1 and 24.2, as well as 24.3 and 24.4, can be assigned to the Y - direction of the vehicle so that when collision forces occur in the Y - direction of the vehicle, the temple 20 with the interior rear - view mirror is allowed to break away from the base 10 in the same way. Here, the forces can act and be absorbed in the XY - plane.

[0058] Figure 3 Shows a schematic side view of an embodiment of the mounting assembly according to the invention, which has Figure 1 the base 10 and Figure 2The temple 20. The bottom 10.1 of the base 10 is hereby arranged on the windshield of the vehicle. It is conceivable here that the diameter of the bottom 10.1 is in the range of 30 mm to 55 mm, preferably in the range of 40 mm to 55 mm, and particularly preferably 40 mm. This compact structural form of the base 10 is achieved by arranging the resistance surfaces 14.1 - 14.6 according to the invention.

[0059] Generally speaking, in the final installation state, one resistance surface 14 and one fixing surface 24 are in contact with each other. As can be seen, for example, from Figure 3 the resistance surface 14.5 and the fixing surface 24.5 are in contact with each other. Here, the base 10 and the temple 20 are held together and pressed against each other by means of a torsion spring 40. Generally speaking, the torsion spring 40 can be arranged in a known manner on the axis of rotation between the base 10 and the temple 20 and can also be connected to the temple 20 first.

[0060] The torsion spring 40 includes at least two engaging arms 40.1 that are opposed to each other. Here, the engaging arms 40.1 are arranged for engaging with the engaging region 18 of the base 10 during installation and in the final installation state, which is explained by means of Figure 4 and Figure 5 to explain.

[0061] Particularly preferably, in the Figure 3 installation assembly, there is a sensor (not shown), such as a rain sensor, arranged for installation on the vehicle windshield. In the final installation state, the sensor and the base 10 are hereby arranged at different positions on the windshield, preferably side by side. Since the sensor is not arranged inside the base 10 on the windshield but outside the base 10, the available structural space can be used advantageously for arranging the resistance surfaces 14.1 - 14.6 and does not have to be used for the sensor. Thereby, a flatter structural height or a smaller diameter of the bottom 10.1 of the base can be achieved.

[0062] Figure 4 Fig. shows a schematic perspective view of an embodiment of the base 10 according to the invention with a torsion spring 40 in a pre-fixed position during installation, where the temple 20 is not shown for better illustration.

[0063] In Figure 4 the preferred embodiment, the torsion spring 40 includes, for example, four engaging arms 40.1, and the engaging arms are respectively inserted into the engaging region 18 of the base 10. However, embodiments with different numbers of engaging arms 40.1 are also conceivable.

[0064] The engagement area 18 is provided on the side wall 16 of the base and has at least two notches 18.1 here, which are arranged between the fixing elements 18.3 protruding from the side wall 16. In addition, a pre-fixing rib 18 is provided for each notch 18.1. The pre-fixing rib 18.2 is arranged, for example, as shown in Figure 4 between the notch 18.1 and the bottom 10.1 of the base 10. Preferably, the fixing element 18.3 protrudes further from the side wall 16 than the pre-fixing rib 18.2.

[0065] During installation, the engagement arm 40.1 in the pre-fixed position based on the notch 18.1 does not act on the fixing element 18.3, but on the pre-fixing rib 18.2. Thus, before the temple 20 is rotated to its final installation position, the temple 20 is pre-fixed on the pre-fixing rib by means of the torsion spring 40 during installation.

[0066] The base 10 and the temple 20 can preferably be designed such that three resistance surfaces 14 are directly reached during installation and these three resistance surfaces do not cause resistance during installation. By reaching the remaining three resistance surfaces 14 during installation, the installation force resistance is thereby defined.

[0067] Here, the pre-fixing surface 26 of the temple 20 is respectively assigned to the boosting surface 15 of the base 10 in the pre-fixed position. As shown in Figure 2 and Figure 3 it can be seen that the pre-fixing surface 26 is respectively opposed to one of the fixing surfaces 24.1 - 24.6, so that the two surfaces have an angle with each other. Correspondingly, as shown in Figure 4 and Figure 5 it can be seen that the boosting surface 15 is respectively opposed to one of the resistance surfaces 14.1 - 14.6, so that the two surfaces have an angle with each other.

[0068] Figure 5 Fig. shows a schematic perspective view of an embodiment of the base 10 according to the invention with a torsion spring 40 in the final installed state, where the temple 20 is not shown for better illustration.

[0069] In the transition from the Figure 4 pre-fixed position in Figure 5 to the final installed state, by rotating the torsion spring 40, for example, one of the pre-fixing surfaces 26 is rotated from its corresponding boosting surface 15 towards the corresponding resistance surfaces 14.1 - 14.6, so that in the final installed state the corresponding fixing surfaces 24.1 - 24.6 abut against the corresponding resistance surfaces 14.1 - 14.6 and are fixed to this resistance surface by the elastic force of the torsion spring 40 as shown in Figure 3 it can be seen.

[0070] It can be conceived on this principle that the three boosting surfaces 15 are respectively crossed by the corresponding pre-fixing surfaces 26, and an installation force resistance is generated here. This is preferably the case for the boosting surfaces 15.2, 15.3 and 15.6. In other words, the pre-fixing surface 26 thus slides towards the final installation state across the corresponding boosting surface 15, in which the fixing surfaces 24.1 - 24.6 abut against the corresponding resistance surfaces 14.1 - 14.6.

[0071] Alternatively or additionally, when rotating from the pre-fixed position to the final installation state, if its pre-fixing surface 26 does not cross the boosting surface 15, the corresponding fixing surfaces 24.1 - 24.6 can rotate towards their corresponding resistance surfaces 14.1 - 14.6, so that they abut against each other and are fixed by the elastic force of the torsion spring 40. This is preferably the case for the fixing surfaces 24.1, 24.4 and 24.5.

[0072] During this rotation process, the engaging arms 40.1 also respectively rotate from the pre-fixing ribs 18.2 to the corresponding fixing elements 18.3 and engage with the fixing elements, thereby generating an elastic force.

[0073] Generally speaking, other shapes of the resistance surfaces 14.1 - 14.6, the boosting surfaces 15, the fixing surfaces 24.1 - 24.2 and the pre-fixing surfaces 26 can also be conceived. In principle, all the above-mentioned elements and surfaces are arranged and oriented in terms of their shapes, heights and angles such that the requirements generated by the corresponding standardizations such as FMVSS 571.111 and ECE-R46 are met.
