DETAILED DESCRIPTION

(11) To begin with, FIG. 1 shows extremely schematically a vehicle 1, in the present case a passenger vehicle, with an inside rearview mirror 2 that is mounted on the windshield 3 of the vehicle 1. The invention is not restricted to an inside rearview mirror 2 mounted on the windshield 3, however, but instead also includes an inside rearview mirror 2 that is mounted on another component of the vehicle 1, in particular a body component of the same, such as a frame element of the windshield 3.

(12) According to FIG. 1 to FIG. 3, the inside rearview mirror 2 has a mirror head 4 that is adjustably mounted, by the agency of a mirror base 5, on a base plate 6 permanently attached to the vehicle.

(13) The base plate 6 is preferably made of a plastic, and in addition is preferably mounted on the windshield 3 by adhesive bonding. The connection between the mirror head 4 and the mirror base 5 is accomplished by means of a ball-and-socket joint 7 (see, in particular, FIG. 3 and FIG. 4). The mirror base 5 is supported on the base plate 6 by means of a first, front support point 8 and a second, rear support point 9.

(14) The first, front support point 8 is formed by two bearing side pieces 10, 11 of the base plate 6 that are spaced apart from each other viewed in the vehicle transverse direction (y-direction), each of which bearing side pieces 10, 11 has a bearing eye 12, 13. The mirror base 5 is mounted within the bearing side pieces 11, 12 by means of one common bearing axle or—according to this exemplary embodiment—by means of one bearing axle 14 apiece so as to be pivotable about a vehicle transverse axis 15 (see, in particular, FIG. 3 and FIG. 4). Preferably, the bearing axles 14 are designed as a single piece with the mirror base 5, and in addition are preferably made of a plastic.

(15) According to this exemplary embodiment, the second, rear support point 9 has two retaining elements 16, 17 that are spaced apart from each other viewed in the vehicle transverse direction (y-direction). Each of these elements is composed of a clamp element or clip element, which is elastic or resilient in design in this exemplary embodiment, and is tightly connected at one end to the mirror base 5 in the present case and at the other end engages in a corresponding opening 18 in the base plate 6 through form-locking and/or frictional connection (see, in particular, FIG. 4 and FIG. 5). The retaining force of the retaining elements 16, 17 is chosen such that these elements detach from the base plate 6 as a result of a specific increased application of force to the mirror head 4 and/or mirror base 5. For example, the said increased application of force can result, as indicated in FIG. 6 by the direction arrow 19, from an impact (force “F”) of the head of a vehicle occupant due to a frontal crash event of the vehicle 1. In this respect, FIG. 6 shows the mirror head 4 along with the mirror base 5 in two operating positions, on the one hand in a functional position “A” (solid lines) for the intended use of the inside rearview mirror 2, and on the other hand in a safety position “B” (dashed lines) into which the mirror head 4 along with the mirror base 5 is pivoted toward the vehicle front as a result of the said head impact (force “F”).

(16) As is further evident from FIG. 2 to FIG. 7, at least one of the bearing side pieces 10, 11 is slotted in design for installation of the applicable bearing axle 14 on the base plate 6 of the mirror base 5. The installation slot 20 extends transversely to the central axis 21 of the bearing eye 12, 13, which corresponds to the aforementioned vehicle transverse axis 15, toward the bearing eye 12, 13. Preferably, each bearing side piece 10, 11 has said installation slot 20.

(17) As is additionally evident from FIG. 2 to FIG. 7, the installation slots 20 (only one installation slot 20 is shown in the present case) are each located in a region of the relevant bearing side piece 10, 11 that faces away from the vehicle front 1a (see FIG. 1) when viewed in the vehicle longitudinal direction (x-direction).

(18) It can furthermore be seen in FIG. 2 to FIG. 7 that at least the section of the bearing axle 14 that can be inserted—transversely to the said central axis 21 of the bearing eye—into the bearing eye 12, 13 of the applicable bearing side piece 10, 11, and that is supported in the bearing eye 12, 13, has a circular cross-section that is reduced by a circular segment 22 (see FIG. 7, in particular), wherein the clearance of the installation slot 20 in the associated bearing side piece 10, 11 is equal to or slightly larger than the diameter “d” of the bearing axle 14 reduced by the height “h” of the circular segment 22. As a result, the installation of the bearing axles 14 of the mirror base 5 on the base plate 6 is permitted only in a hypothetical pivoted position “C” of the mirror base 5 oriented toward the vehicle front (see the situation in FIG. 7), in that the bearing axles 14 are inserted into the relevant installation slot 20 in said pivoted position “C” in accordance with the direction arrow 23 from vehicle rear to vehicle front, and are guided to the bearing eye 12, 13. Pivoting the mirror base 5 back causes the retaining elements 16, 17 to be inserted into the respective associated opening 18 of the base plate 6 in a locking manner (see the situation in FIG. 4).

(19) Easy installation of the mirror base 5 on the base plate 6 when the mirror base 5 is in the state pivoted toward the vehicle front is ensured as a result of this joint, and in addition, a spontaneous exit of the bearing axle(s) 14 from their bearing eyes 12, 13 is prevented even better over a large pivot angle. The pivoted position “C” (FIG. 7) for installation of the mirror base 5 may possibly also arise in the loading case salient to the invention or in the said crash case (frontal crash), but in that case the forces then act on the mirror base 5 and its bearing axle(s) 14 such that the latter are subjected to forces opposite the relevant installation slot 20 in the associated bearing eye 12, 13, and thus cannot exit the bearing eye 12, 13 in question through the said installation slot 20.

(20) The variant embodiment of the invention from FIG. 8 and FIG. 9 differs from the above-described variant embodiment firstly by a different design of the second, rear support point 9. This support point 9 is distinguished by a retaining element 25 in the form of a retaining spring mounted on the mirror base 5 from the outside by means of at least one screw 24, which spring is designed with at least one lock 26 that locks under preloading with a mating lock 27 of the base plate 6 in the installed state. The retaining spring is composed of a spring steel sheet which, according to this exemplary embodiment, has a lock 26 in the form of a shaped projection that is received in a form-locking manner by the mating lock 27 in the form of a recess in the base plate 6. However, the invention is not limited to one lock 26, but also encompasses two or more lock 26 on the retaining element 25, or two or more retaining elements 25 equipped with at least one lock 26.

(21) The retaining force of the retaining element 25 is chosen such that the element detaches from the base plate 6 as a result of a specific increased application of force to the mirror head 4 and/or mirror base 5. In conformity with the above-described first variant embodiment of the invention (see FIG. 6), the said increased application of force can result, for example, from an impact (force “F”) of the head of a vehicle occupant as a result of a frontal crash event of the vehicle 1.

(22) Also shown in FIG. 9 is a base plate 6 that has, on the windshield side, an opening 28 for placement in the same of a sensor, such as, e.g., for placement of a rain sensor or the like. Such an opening can also be provided in the base plate 6 according to the first variant embodiment of the invention, and accordingly is also included by the invention.

(23) The above-described exemplary embodiments are directed toward retaining elements 16, 17; 25 in the form of clamp elements or clip elements or a retaining spring 25, which are connected or can be connected to the base plate 6 through form-locking and/or frictional connection. However, the invention is not limited to these concrete joints, but instead also includes retaining elements 16, 17, 25 that are tightly connected to both the mirror base 5 and the base plate 6, but each have a predetermined breaking point that breaks or fails as a result of increased application of force.

(24) Furthermore, the invention also is not limited to the preferred embodiment of the base plate 6 with two slotted bearing side pieces 10, 11, but instead also includes an embodiment in which only one of the bearing side pieces 10, 11 is slotted in design. In this case, in contrast to the above-described embodiment, installation takes place in such a manner that the hypothetical pivoted position “C” already described above of the mirror base 5 (FIG. 7) is established first, after which one bearing axle 14 is inserted axially or as axially as possible from the inside of the bearing side piece into the bearing eye 13 of the unslotted bearing side piece 11, and finally the other bearing axle 14 is inserted into the bearing eye 12 of the other bearing side piece 10 as already described above, namely transversely to the central axis 21 of the said bearing eye 12.

(25) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
