Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a main pivot bearing consisting of a main support bearing and a sun visor shaft, which is arranged in one end region of the longitudinal edge of the upper part, and a main pivot bearing, which is arranged in the other end region. , a sun visor for a vehicle having a counter-bearing shaft removably coupled to a plastic counter-bearing bearing, and a mirror having a light source to which a power supply conductor and a ground conductor contactable to a power supply of the vehicle are connected. , the counter-bearing bearing has at least one contact element, on one side of which an electrical conductor of the vehicle's power supply can be connected and on the other side at least a power supply conductor for a light source. This relates to a type in which the contact bodies of the opposing bearing shafts are in contact with each other.

In the case of a sun gauge of the type described above, the opposing bearing shaft has two contact bodies with an insulator interposed between them. For this purpose, the counter-bearing shaft is constructed in a telescopic manner and consists of an intermediate plastic part with integrally molded pins at both ends and a metal sleeve arranged over said pins, in this case plastic. A coil spring is placed between the member and the metal slit, which is time consuming.

SUMMARY OF THE INVENTION It is therefore an object of the invention to provide a sun visor of the type mentioned at the outset with simple manufacturing and assembly.

According to the invention, this object is achieved in that the counter-bearing shaft is formed in one piece with the plastic bearing and has at least one, preferably two, contact bodies connected to an electrical conductor. The contact body is held form-fittingly in a groove-shaped radial groove of the counter-bearing shaft, and the outer surface of the contact body partially coincides with the outer circumferential surface of the counter-bearing shaft, or This problem was solved by making the support shaft protrude slightly from the outer peripheral surface. Manufacture and assembly are significantly simplified by integrating the plastic bearing and the counter-bearing shaft into one component.

In a further advantageous embodiment, each contact body is designed as a sleeve with a slit, to the two longitudinal edges of which a diverging wave is integrally connected, and furthermore, the free longitudinal edge of the respective web comprises: It has an outwardly curved portion that matches the curvature of the opposing bearing shaft. The advantage of such an embodiment is that the electrical conductor can be inserted into the sleeve and retained therein by a simple compression of the sleeve, and then the contact body can be pressed into the tapered groove of the counter-bearing shaft. Or, you just have to do it in a snap.

However, it is also possible to optionally form one or each contact body as a gripping piece, which gripping piece is partially wrapped around the counter-bearing shaft and is supported by at least one free longitudinal edge bent inwards. It projects into a radial groove in the shaft and contacts an electrical conductor inserted into the axial bore of the counter-bearing shaft. To attach the gripping piece, the gripping piece is hooked into the radial groove, for example by one bent longitudinal edge, then wrapped around the counterbearing shaft and then concentrically into the counterbearing shaft by the other longitudinal edge. Press it against a conductor placed on the ground. Since the counter-bearing shaft is made of plastic and thus has a certain return elasticity, the gripping piece is deformed by an initial stress that ensures constant contact with the electrical conductor. Furthermore, the gripping piece can be brought into contact with a conductor which is press-fit into the C-shaped groove and which is arranged in the axial bore in the opposing bearing shaft between the longitudinal edges that are pressed together. In this case, it is advantageous if the longitudinal edges of the gripping piece are tooth-shaped. This is because this results in a satisfactory contact engagement.

Furthermore, in a particularly advantageous embodiment of the invention, the plastic support is formed in one piece with the reinforcing insert of the sun visor body. With such an embodiment, it is only necessary to mount the contact body on the counter-bearing shaft.

Next, the present invention will be specifically explained with reference to the illustrated embodiments.

The sun visor body 1 according to FIG. A main swing bearing is arranged. In the other end region of the upper longitudinal section 2, a counter-bearing is provided which consists of a counter-bearing shaft 5 and a counter-support bearing 6. A mirror 7 is disposed on the surface of the sun cruiser body 1 facing the passenger compartment when the sun cruiser is turned downward, and a lamp 8
Switch operable by flip-up lid (not shown)
Can be flashed via. Mirror 7 and lamp 8 are arranged in a conventional manner and will therefore not be described in detail individually.

FIG. 2 shows the counterbearing bearing 6 in a perspective view. Furthermore, as can be seen in FIG. 2, the counter-bearing bearing 6 is provided with two contact elements 11 for electrical connection with the electrical conductor 10 of the vehicle's power supply, the upper area of which is a contact plug. and the lower region is configured as a contact spring. Contact between the electrical conductor led to the lamp 8 and the contact member 11 takes place via a contact member arranged on the opposing bearing shaft 5, in which case the contact member 11 and the contact member are contact when the easer body occupies at least a downwardly pivoted position;

The embodiment shown in FIG. 3 shows a counter-bearing shaft 5 which is constructed in one piece with a plastic bearing 12. The embodiment shown in FIG. In this case, the counter-bearing shaft 5 has a tapered radial groove 13 extending from a central axial bore, in which two contact bodies 14 are arranged. The contact bodies 14 each consist of a sleeve 15 with a longitudinal slit,
The sleeve has a web 16 integral with the longitudinal slit, the free end of which is curved outwards (see diagram). Each sleeve 15 receives an insulated electrical conductor 17 at its end.

The necessary connection is effected by soldering, but preferably by pressing along the crimp section 18. Owing to the special shape of the contact body 14, it is simply fixed by snapping into the tapered radial groove 13 of the pack. The outer surface of the outwardly curved tongue piece 16a of the contact body 14 is aligned with the outer peripheral surface of the opposing support shaft 5 or protrudes slightly from the outer peripheral surface of the opposing support shaft 5, so that contact between the contact member 14 and the contact member 11 is prevented. A reliable contact engagement with the spring is obtained. The radial grooves 13 are interrupted between the solid contacts 14 by webs 19, so that the solid contacts are electrically isolated from one another. If the insertion frame 20 and the sensor shaft 4 are made of metal, only one contact body can be provided instead of the solid contact body 14. In FIG. 1, the insert frame made of metal wire is shown in chain lines. When the insertion frame 20 and the sun visor body are made of metal, the light source 8 is grounded to the vehicle body via the sun visor shaft and the insertion frame 2o. On the other hand, in the case of a plastic insert, which may be formed in one piece with the plastic bearing 12, the supply conductor as well as the ground conductor can be led to the light source 8 via a counter-bearing bearing 6 (see FIG. 3). . In this case the electrical conductor 17.17a connected to the contact 14
is guided directly to the lamp 8 inside the sun visor body 1.

FIG. 5 shows the opposing bearing shaft 5a which is formed integrally with the plastic bearing 12a. Opposing support shaft 5a
has an axial bore 21 into which a radial groove 13a opens (see also FIG. 6).

An electrical conductor 17 is inserted into the axial bore 21 and comes into contact with a contact body 14 which is designed as a gripping piece 22 . The gripping piece 22 has an approximately circular shape with tongues 23,24 bent inward at the free longitudinal edge.
, the shorter tongue piece 23 of the tongue piece is hooked in the radial groove 13a, and the free longitudinal edge of the longer tongue piece 24 is It is pressed into the radial groove 13a in such a way that it contacts the electrical conductor 17 very reliably.

FIG. 7 shows the opposing bearing shaft 5b, which is formed integrally with the plastic bearing 12b. The embodiment according to FIG. 7 differs significantly from the embodiment according to FIG. The edges are arranged in radial grooves facing each other in the diametrical direction of the counter-bearing shaft 5b, and between the longitudinal edges there is an electrical conductor 17.
is in contact with. In this case, as shown, the two vertical lines are preferably tooth-shaped.
