Holding device for holding a vehicle component on a pane surface of a motor vehicle

Abstract

A holding device holds a vehicle component such as an internal rear view mirror on a pane surface of a motor vehicle. The holding device includes a base element having a fastening surface for attachment to the pane surface of the motor vehicle, a cover part for fastening to the base element and for holding a foot element, wherein the cover part is held on the base element by engaging at least one pin in an associated recess in a holding element of the cover part. The holding element has an auxiliary recess which is arranged offset to the recess in a direction of extension such that when force is applied in the direction of extension with an amount of force which is greater than a threshold amount, the cover part shifts on the base part and the at least one pin is at least partially accommodated in the auxiliary recess.

DETAILED DESCRIPTION OF THE DRAWINGS

(10) FIG. 1 shows a side view of a holding device 2 which is mounted on a windscreen 1 of a motor vehicle and has a cover part 3 on which an adjustable mirror device 5 as an example of a windscreen-mounted vehicle component is arranged via a mirror foot 4 in order to form an interior mirror device of a motor vehicle. The cover part 3 adjoins a roof lining 6 and extends in the lateral direction along the windscreen 1 approximately in the center of the windscreen 1 and in the longitudinal direction of the motor vehicle in the direction of a lower edge of the windscreen 1.

(11) As is shown in the side view of FIG. 2 with the cover part 3 removed, a base element 8 for holding the foot element 4 is attached to the windscreen 1 in the region of the cover part 3 to be placed on. The base element 8 can be designed, for example, as a base plate. FIG. 3 shows a sectional view along the intersecting line A-A of FIG. 2. The base element 8 can be connected fixedly to the windshield 1 in particular by adhesive bonding of a fastening surface 83 on the inner surface of said windshield 1. The base element 8 serves to reliably hold the cover part 3 on the windshield 1. For the installation, the cover part 3 is placed onto the base element 8 and fastened thereto.

(12) The cover part 3 is of shell-shaped design and, in the state placed onto the base element 8, completely overlaps the base element 8 and covers the latter, with the edges of the cover part 3 preferably lying against the inner surface of the windshield 1. For this purpose, the cover part 3 has an upper side 34 and side surfaces 35 which surround the latter and flatly cover the covered part of the windshield 1. The side surfaces 35 are entirely or partially arranged on the edges of the upper side 34 and protrude in the direction of the windshield 1. The base element 8 can be covered visually by the cover part 3 by being accommodated in the cover part 3.

(13) Pins 81 which in particular protrude opposite each other and serve for holding the cover part 3 on the base element 8 are provided at the sides of the base element 8. The pins 81 are projections which can have substantially any desired cross section.

(14) FIG. 4 shows a view of the lower side of the foot element with a holding element 31 for receiving a mirror foot (not shown in FIG. 4). At the sides of the holding opening 31, holding elements 32 are provided which, as shown in the sectional view along the intersecting line B-B of FIG. 5, are fastened to the cover part 3 and each have a recess 33. The recess 33 has a substantially rectangular cross section and serves for receiving the pins 81 of the base element 8 in the mounted state. The width B of the recess 33 substantially corresponds to the width of the pins 81 to be received therein.

(15) As illustrated in FIGS. 5 and 6, the holding element 32 has an extension of the recess 33 which can be designed in the form of a laterally arranged auxiliary recess 36. The auxiliary recess 36 is arranged laterally next to the recess 33 and is separated from the latter by a narrow web 37 (see FIGS. 5 and 6) or is connected to said recess such that a single approximately L-shaped recess is formed, as illustrated in FIG. 7.

(16) In the assembled state, the pins 81 are accommodated in the associated recess 33 of the holding element 32. The extension of the recess 33 by means of the auxiliary recess 36 enables the cover part 3 to be displaced relative to the base element 8. In the event of an action of force on the cover part 3 in the longitudinal direction L, the auxiliary recess 36 enables the cover part 3 to be able to be displaced along the fastening surface 83 in a direction transversely with respect to the direction of extent of the pins 81. The pins 81 move here in the direction of the auxiliary recesses 36 and are at least partially accommodated in the respective auxiliary recess 36.

(17) The auxiliary recess 36 can be connected to the recess 33 in such a manner that a movement of the cover part 3 on the base element 8 is permitted only as soon as the force amount of a corresponding action of force in the longitudinal direction exceeds a predetermined threshold amount.

(18) In order to define the threshold amount which is necessary in order to permit a movement between the cover part 3 and the base element 8 in the longitudinal direction L, the strength of the web 37 arranged between the recess 33 and the auxiliary recess 36 can be dimensioned in such a manner that, when a force amount exceeding the threshold amount acts along the fastening surface 83 and transversely with respect to the direction of extent of the pins 81, the web breaks and the pin 81 moves in the direction of the auxiliary recess 36 and into the latter.

(19) FIG. 7 shows the situation, corresponding to FIG. 6, in which the cover part 3 is displaced in relation to the base element 8 by an action of force.

(20) FIG. 8 shows a side view of the foot element 4 for holding the mirror device 5. The foot element is inserted with a holding part 42 integrally formed thereon into the holding opening 31 of the cover part 3 and is provided with studs 41. The studs 41 are arranged in such a manner that they engage in the respective recess 33 and the foot element 4 is thus held on the cover part 3. Both the associated pin 81 and the stud 41 are therefore accommodated and held in each of the recesses 33.

(21) By the pins 81 being received in the recesses 33 of the holding elements 32, the cover part can be reliably held on the base element 8. In particular, the holding elements 32 on the cover part 3 and the width of the base element 8 can be designed in such a manner that, when the cover part 3 is placed onto the base element 8, the mutually facing sides of the holding elements 32 lie against lateral outer surfaces 84 of the base element 8 in order to ensure protection against rotation of the cover part 3 on the base element 8.

(22) FIG. 9 illustrates a sectional view through the cover part 3 and the base element 8 in a locked state. It is seen that the pins 81 project into the recess 33 of the holding element 32 and are held there.

(23) In order to ensure a fixed fit of the cover part 3 on the base element 8, when the pin 81 engages in the recess 33 that side of the pin 81 which faces the windshield 1 and that edge 39 of the recess 33 which faces the pin lie against each other with force, and therefore the cover part 3 is reliably held on the base element 8 and at the same time is pressed with the side surfaces 35 onto the windshield 1. As a result, in particular in the embodiment in which the recess 33 and the auxiliary recess 36 form a common L-shaped recess, the threshold amount of the force which is required for displacing the cover part 3 in relation to the base element 8 can be adjusted by the friction between the side of the pins 81 and the edge 39 of the recess 33.
