Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a sun visor, comprising: a pivot bearing arranged in one end section of the upper longitudinal edge and consisting of a pivot bearing casing and a sun visor shaft; a counter-bearing shaft arranged in the end section of the visor and removably connected to a counter-bearing casing made of synthetic resin; a mirror arranged in the sun visor body; and a light source supplied from the vehicle electrical system for illumination. , the counter-bearing casing has in the bearing opening at least one electrical contact element connected to the vehicle electrical system, and the counter-bearing shaft has at least one counter-contact element connected to the light source. Concerning forms that have the following.

In the known sun visor of the above type (German Utility Model No. 7702394), the mirror is provided with a cover plate, which is mounted on the upper mirror edge so as to be pivotable about a horizontal axis. has been done. The cover plate is provided with a light source on the back side of the upper edge section. Furthermore, the cover plate is provided with a spring that holds the cover plate itself in the open pivoted position and a locking member that holds the cover plate itself in the closed pivoted position.
When moving the cover plate from one end position to the other end position, the electrical contacts are either disconnected from one another or connected to one another. A number of significant disadvantages arise in the known construction of sun visors with illuminated mirrors. In this case, the construction cost of the lighting device is particularly high, the number of required components is large, and the assembly costs are therefore high.

It is therefore an object of the invention to save costs in a sun visor of the type mentioned at the outset due to a small number of components and simple manufacture and assembly.

In order to achieve this objective, the configuration of the present invention includes:
The counter-bearing shaft extends into the sun visor body in a recess for accommodating the counter-casing, which is provided in the end section of the upper longitudinal edge of the sun visor body, corresponding to the counter-bearing casing, in the core material formed from the wire frame. It consists of a section extending parallel to the upper longitudinal edge and a synthetic resin body with a circular cross section fitted over the section of the core material, and the opposing contact member of the opposing bearing shaft pivots the sun visor body downward. The contact member of the counter support casing is disposed on the circumferential surface of the synthetic resin body having a circular cross section of the counter support shaft so as to be connected to the contact member of the counter support casing at the opposite position. Such an arrangement avoids the arrangement of a cover plate with contact elements and thus reduces manufacturing and assembly costs.

Next, embodiments of the present invention will be specifically described using the drawings.

A sun visor body 1 of the sun visor is arranged in one end section of the upper longitudinal edge 2 of the sun visor body and includes an axle bearing casing 3 and a sun visor shaft 4.
a pivot bearing 5 consisting of a pivot bearing 5, a counter-bearing shaft 6 arranged in the other end section of said longitudinal edge and removably inserted in a counter-bearing casing 7 made of synthetic resin; and a mirror 8 illuminated by at least one light bulb 10 as a light source.

As is clear from Fig. 2, the sun visor body 1
has a chamber-shaped notch 11 that is open toward the wide side, and a rectangular box 12 is placed within this notch. The box 12 advantageously contains the sun visor body 1
Embedded in foam during manufacturing. Box 12 holds frame 9 using, for example, clips (not shown). As is clear from FIG. 2, the frame 9 has a T-shaped cross section. In this case, the horizontal section foot 13 of the T-shaped cross section of the frame is configured such that the surface on the side of the vertical section leg 14 of the frame serves as stop surfaces 15 and 16. The stop surface 15 supports the mirror 8 in an annular manner, whereas the stop surface 16 rests on the edge section of the recess 11 in the sun visor body 1 and on the free end face of the box 12. The sun visor body 1 advantageously has a recess in the section supporting the frame, so that the frame 9 is arranged to be sunken into the sun visor body, so that the outer surface of the cross-sectional foot of the frame substantially extends into the sun visor body. It forms the same surface as the exterior of 1.

Contact springs 20 are arranged at the bottom 19 of the box, and a light bulb 10 is mounted between the contact springs. One or more light bulbs 10 are placed within the box 12 depending on the desired luminous intensity.

The counter-support shaft 6 extends inside the notch of the core member 33 formed from a wire frame, which accommodates the counter-support casing 7, which is provided in the end section of the sun visor main body 1 in correspondence with the counter-support casing 7. It consists of a section extending parallel to the longitudinal edge 2 and a synthetic resin body 21 having a circular cross section, which is fitted over the section of the core material 33. A synthetic resin body 21 made of a relatively soft material is constructed with two longitudinal slits 22, 23 extending parallel to each other over the entire length. Vertical slit 23
has a notch 24 located approximately in the center and open toward the outer peripheral surface of the synthetic resin body 21. A counter-contact element designed as a sheet-metal strip 25 is inserted into the longitudinal slot 23 and has a curved section 26 with a contact protrusion 27 which is pushed in towards the outside. It protrudes from a notch 24 in the synthetic resin body. By means of the curved section 26 the sheet metal strip 25 is axially fixed immovably and the contact projection 2
7, elastic support is obtained. The cross section of the sheet metal strip 25 corresponds to the cross section of the slit 23, so that the sheet metal strip is also held against rotation. In addition, the sheet metal strip 25 has, in its end section projecting from the plastic body, an extension 28 which is bent over and equipped with a locking pin 29, so that the extension 28 receives the cable clamp 30 in a secure manner. From the cable grip, a conductor 31 leads to a light bulb 10, which is arranged between the contact springs 20 or received in a socket.

In order to fix the synthetic resin body 21 in a non-rotatable and axially movable manner, a section of the core member 33 extends in a notch provided in the left end section of the upper longitudinal edge 2 of the sun visor body 1. has a chamfered portion 32. Before the core material 33 is welded together as a wire frame, the synthetic resin body 21 is inserted up to the chamfered portion 32 of the core material 33 under the elastic action of the synthetic resin body itself. The synthetic resin body 21 can be welded to the exterior of the sun visor body 1, resulting in a clean transition at the contact point between the exterior of the sun visor body and the synthetic resin body.

The counter-bearing casing 7 is of substantially known construction, but as shown in FIG.
It differs from known opposed bearing casings in that it is equipped with: The contact element 35 consists of a sheet metal strip, the lower section of which forms a curvature with a semicircular diameter approximately corresponding to the radius of the bearing opening 34 and is preferably guided in a groove 36. With its upper end section, the contact element 35 protrudes from the housing slot 37 and has a cable grip 38 there, in which case a conductor 39 connected to the cable grip can be connected to the vehicle electrical system and advantageously are placed together in the circuit of the vehicle lighting system.

The arrangement of the contact member 35 and the arrangement of the opposing contact portion (contact protrusion 27) are such that the contact member 35 is disposed only when the sun visor body 1 is pivoted downward from the inactive position to the active position (a position that allows use of the mirror 8). 35 and a counter contact.
