[0002] REARVIEW DEVICE FOR A MOTOR VEHICLE

[0003] The invention relates to a rearview device for a motor vehicle.

[0004] Rearview devices for motor vehicles come in various forms. These can, for example, include a motor vehicle's exterior mirror, which allows the driver to see traffic behind them.

[0005] Known rear-view devices are attached to the vehicle by means of a mounting in the vehicle structure. They are positioned in a pre-assembled functional position within the mounting in the vehicle structure and then moved into a final, assembled position by means of a rotational movement around an axis of rotation that runs parallel or at an angle to the vehicle's transverse axis.

[0006] The rear-view devices incorporate delicate sealant elements on their base elements, which are used to attach the rear-view devices to the vehicle structure. When moving the rear-view device from its pre-assembled functional position to its final assembly position, it is never entirely possible to completely rule out the possibility that the sealant will not slide into the correct position, but instead become compressed or jammed. This proves disadvantageous because the unfilled gap where the sealant should be located creates a kind of air channel, through which, for example, noise generation during vehicle operation can never be completely eliminated.

[0007] One object of an embodiment of the invention is to propose a rearview device for a motor vehicle in which the rearview device is arranged in a better sealed manner in the joined end position.

[0008] This problem is solved by a rear-view device for a motor vehicle with at least one base element by which the rear-view device can be fixed or secured to a receptacle of a vehicle structure, wherein the base element can be moved from a pre-assembled functional position, in which the base element is arranged in the receptacle, by a rotational movement about an axis of rotation running parallel or oblique to the transverse axis of the vehicle into a joined end position, in which the base element is secured in the receptacle, with at least one sealing means which is arranged at least sectionally on an outer surface of the base element circumferentially with respect to the axis of rotation and which, in the joined end position, is in contact with the receptacle, and with at least one clamping means by which at least one sealing section of the sealing means is clamped in the direction of the receptacle, at least in the joined end position, to bear against the receptacle.

[0009] Because the back-end device includes a clamping element by which at least one sealing section of the sealant is tensioned towards the receptacle, at least in the assembled end position, it can be ensured that the sealant assumes its desired final position in the assembled end position. This prevents unwanted air channels from forming between the back-end device and the receptacle of the vehicle structure.

[0010] The clamping device allows the sealant itself to function without necessarily needing to exert sufficient spring force to automatically move into the desired final position. This function can be performed solely or additionally by the clamping device.

[0011] In principle, it is conceivable that the sealing section is formed at any point on the base element. In embodiments of the back-view device, it proves advantageous if the sealing section of the sealant is arranged at a corner region of the base element, particularly one comprising an acute angle.

[0012] This ensures that the sealing section and the clamping device functionally assigned to the sealing section are provided at a particularly critical point of the base element, where the risk of not assuming the desired end position is particularly high when transferring from the pre-assembled functional position to the assembled end position.

[0013] The sealing section can, in principle, be of any shape, provided it fulfills its function of resting against the receptacle in the assembled final position. In such a case, the sealing section of the sealant can rest against the receptacle in a linear or surface manner.

[0014] It proves advantageous if the sealing section is lip- or rib-shaped and extends away from the base element in a direction transverse or oblique to the axis of rotation and / or if the sealant in the sealing section encompasses its weakest area in a direction parallel to the axis of rotation.

[0015] The sealant can, in principle, be made of any material, provided it fulfills its function of sealing against the fitting in the assembled final position. It proves cost-effective if the sealant, and in particular the sealing section of the sealant, comprises a plastic, rubber, or sealing foam.

[0016] Furthermore, embodiments of the retrospective device are conceivable in which at least one of the at least one clamping means is arranged between the sealing section of the sealant and the base element and / or in which at least one of the at least one clamping means is arranged in the joined end position between the sealant and the receptacle.

[0017] If the clamping device is positioned between the sealing section of the sealant and the base element, the clamping device can space the sealant away from the base element. In this case, the sealant and the base element can each be in direct contact with the clamping device.

[0018] If the clamping device is positioned between the sealant and the receptacle, the clamping device can, for example, rest against an outer surface of the sealant and press the sealing section of the sealant into the desired final position in the joined end position.

[0019] At least one of the at least one clamping device may comprise a component that is separate or separable from the sealing device and / or the base element.

[0020] In order to ensure that the sealing section of the sealant can be moved into the desired arrangement in the joined end position, it is advantageous if the sealing section of the sealant is arranged on a first side of the corner region of the base element, in particular comprising an acute angle, and if at least one of the at least one clamping means is arranged on a second side of the corner region of the base element, in particular comprising an acute angle, adjacent to the first side, wherein the first side and the second sides enclose the angle of the corner region.

[0021] In such a case, the clamping device can be positioned between the sealant and the receptacle and build up a pressure by which the sealing section of the sealant is moved into the desired arrangement in the joined end position.

[0022] Furthermore, embodiments are conceivable in which at least one of the at least one clamping means and the sealing means form a common one-piece component and / or in which at least one of the at least one clamping means and the base element form a common one-piece component.

[0023] If the clamping device and the sealing device form a single, one-piece component, the back-view device can be designed with a reduced number of components.

[0024] This applies equally if the clamping device and the base element form a single, integrated component.

[0025] The clamping device can, in principle, be of any design. In one embodiment of the back-view device, it proves advantageous if at least one of the at least one clamping device comprises at least one clamping rib projecting transversely or obliquely beyond the sealing element to the axis of rotation, which in particular extends parallel to the axis of rotation to its longest extent and which rests against the receptacle in the assembled end position.

[0026] In particular, if clamping means and sealing means form a common one-piece component, the clamping rib projecting across the sealing means transversely or obliquely to the axis of rotation may be formed by a surface section of the sealing means.

[0027] In a further development of the latter embodiment, it proves advantageous if the at least one clamping device comprises at least three clamping ribs running parallel to each other and spaced apart from each other without contact, which in particular each extend parallel to the axis of rotation to their longest extent.

[0028] This allows the clamping force acting on the sealing section of the sealant to be further increased.

[0029] Further features, details and advantages of the invention will become apparent from the attached patent claims, from the graphic representation and the following description of a preferred embodiment of the backview device.

[0030] The drawing shows:

[0031] Figure 1 shows a top view of an area of ​​a rear-view device according to the invention in the joined end position;

[0032] Figure 2 shows a perspective side view of the embodiment of the rearview device according to Figure 1 in an unassembled arrangement;

[0033] Figure 3 shows a perspective detail view of a corner area of ​​the embodiment of the rearview device according to Figure 1 in the unassembled arrangement.

[0034] The figures show a rearview device for a motor vehicle, designated with reference numeral 2 (not explicitly shown in the figures).

[0035] The rearview device 2 comprises a base element 4 by which the rearview device 2 can be fixed to a receptacle 6 of a vehicle structure 8.

[0036] The rearview device 2 can be arranged in the receptacle 6 in a pre-assembled functional position. By moving it about a pivot axis 10 running parallel or obliquely to the vehicle's transverse axis, the rearview device 2 can be moved from the pre-assembled functional position to an assembled end position. Figure 1 shows the rearview device 2 in the assembled end position. The rearview device 2 comprises a sealing element 12, which is arranged at least partially on an outer surface of the base element 4 that is circumferential with respect to the pivot axis 10 and which, in the assembled end position, rests in contact with the receptacle 6.

[0037] Furthermore, the retrospective device 2 includes a clamping means 14 by which at least one sealing section 16 of the sealing means 12 is clamped in the direction of the receiving 6, at least in the joined end position.

[0038] In the embodiment shown in the figures, the rear-view device 2 comprises three clamping means 14 formed by clamping ribs 18. The clamping ribs 18 extend parallel to the axis of rotation 10 and are arranged parallel to each other, spaced apart from each other without contact, on an outer surface of the sealing means 12. The sealing means 12 and the clamping means 14, in particular the clamping ribs 18, form a single, integral component.

[0039] The figures show that both the sealing section 16 of the sealant 12 and the clamping element 14 are arranged in a corner region of the base element 4 that forms an acute angle. The sealant 12 is arranged on a first side 20 of the corner region of the base element 4, and the at least one clamping element 14 is arranged on a second side 22 adjacent to the first side 20. The first side 20 and the second side 22 together enclose the acute angle of the corner region and are directly adjacent to each other.

[0040] Figure 1 shows the back-end device 2 in its assembled final position. In this position, the sealing section 16 of the sealing element 12 is pressed into the desired position by the clamping means 14. This ensures that no gap is left between the receptacle 6 and the back-end device 2, which could, for example, form an air channel.

[0041] Figures 2 and 3 show the rearview device 2 in an unassembled arrangement.

[0042] Figures 2 and 3 show that the sealing element 12, in particular the sealing section 16 of the sealing element 12, has its shortest extent in the direction parallel to the axis of rotation 10, i.e., it is delicate or thin. Furthermore, Figures 2 and 3 show that the clamping element 14, in particular the clamping ribs 18, has its longest extent in the direction parallel or oblique to the axis of rotation.

[0043] The features of the invention disclosed in the foregoing description, in the claims and in the drawing may be essential, both individually and in any combination, in the realization of the invention in its various embodiments within the scope of protection of the following claims.
