Swivel bearings for vehicle sun visors

The innovation relates to a swivel bearing for blinds of vehicles, in which the bearing axis consists of a dimensionally stable material and has a non-cylindrical structure in the design, such that the bearing axis and Bearing axis receptacle are fixed without additional parts xn axis direction and that the bearing receptacle having little bearing blocks made of a hard material that regresses in its basic shape after a slight deformation set plastic is made.

It is already known to make folding bearings for sun visors or the bearings in sun visor bodies structurally simple and also inexpensive in terms of material and short-term assembly, but such simple designs for swivel bearings could not be used so far, because the first-mentioned bearings can be used from to The space available can be designed with a long axis, and they only require a relatively small amount of drainage because, in relation to these bearings, no position of the sun visor body has a larger lever arm. With the swivel bearings, on the other hand, the sun visor body is held with its greatest length in the sense of a one-armed lever, so © is irftig in a much greater torque.

Through the German utility model 7 433 993 a pivot bearing for sun visors has become known «in which the above Disadvantages are largely avoided by a construction based on a simple design, but must For functional reasons, the bearing mount is made of a less rigid material, so that the bearing axis is in Swing direction of tumble. This always creates a one-sided load, which results in a deformation of the position axis runs out and results in an uncontrollable hanging position of the sun visor body, so that there is always an additional

It is the task of the innovation to have an onnenble: the swivel bearing

to create something that is easy and cheap to manufacture, complete

animalable and to be mounted on the vehicle, the basic position secures the bearing axis and has a sufficiently long service life that maintains the same torque.

According to the invention, the object is essentially achieved in that the bearing axis faces the freely expiring enoe has one or more conically tapered sections and in a mushroom which protrudes a bit over the final cross-section and forms the pull-out lock of the bearing axis ends, with the coordinated dimensions of the bearing cone and bearing uptake in the sense of a press fit.zes are formed. The conically tapered formation of the Lagaraehse together The free end of the bearing and the adapted bearing receptacle can do that

existing warehouse can be completed 1st. However, it is crucial that the bearing is made of a dimensionally stable material can be «ao that the bearing axis is guided safely and linearly and for a sufficiently long service life that retained original torque that was structurally abandoned remains.

If a particularly large torque related to the size is required, it proves to be expedient if either the bearing cone or cones or the bearing receptacle has an oval cross-section and the other part has a round cross-section, wherein the outer surfaces of the bearing cone and bearing mount are the same are made large, because the radially closer together areas of the bearing axis mount an additional, exert elastic pressure on the bearing axis within certain limits.

If, despite the hard setting of the material for the bearing, a certain radial elasticity is to be present, it turns out it is expedient that the bearing receptacle is thin-walled and / or with coaxial air gaps is equipped and the outer wall has a single or multi-stage harpoon training, which is used as a plug-in attachment in Breakthroughs can be used. The constructively given up This is because elasticity is canceled again when the pivot ™ bearing is inserted into openings in the body. with their edge act on the outer wall of the bearing receptacle.

In order to achieve a particularly large impacting effect, the outer walls can be a contact surface for the opening the body wall should be flaps folded inwards.

In the drawing, the innovation is shown in simplified form in several versions.

Show it:

Fig. 1, 2 and 3 pivot bearings in different designs in longitudinal section ^

4 shows a further exemplary embodiment of a pivot bearing in a cutout.

In general, 1 is a bearing block and 2 is a Designated bearing axis. A plastic is required as the material for the bearing block 1, which is inherently dimensionally stable is, however, has a slight, receding elongation. Dimensional stability and elongation are, however, kept in such a way that a SelLjttaktige adaptation of the bearing seat 3 of the bearing block for the bearing axis 2 does not take place, but the outer surface of the bearing axis 2 with the adjacent area of the bearing nahine 3 matches, the sizes to each other like that are matched that there is a lighter press fit that the necessary torque, which a sun visor pivot bearing has to iron, forms.

In the embodiment according to FIG. 1, the bearing block is provided with a flange 4 with screw-on positions. the Bearing axle receptacle 3 is slightly conical, with the conically tapered part facing away from the entrance. the Bearing axis 2 has a compensating conical area and is provided at the free end with a mushroom 5, which with its circumferential edge, the bearing axis receptacle 3 engages behind a piece. For suitable assembly of these two parts, the bearing block 1 and the bearing axis 2, it is appropriate that the edge or the approach of the mushroom 5 is smaller than the

7531982 26.0176

the largest width of the bearing axis mounts is 3. This is a safe approach for driving through the bearing axis 2 given, depending on the setting of the material for the bearing block 1 devices are necessary because the insertion is not possible by hand or is too tiring in the assembly kit. Ufa driving in the bearing axis 2 in the last area of the To favor bearing receptacles 3 are the bearing axis receptacles 3 assigned slots 6 running in the axial direction, the length of which *? Axle mount would take about a third of the length of the bearing 3 matters.

In the exemplary embodiment according to FIG. 2, only the bearing axis 2a is opposite to the bearing axis 1 according to FIG. 1, however thus also the bearing axis receptacle 3, modified, namely the one recorded by the bearing axis receptacle 3 Area of the bearing axis 2 from several cones that are directed against each other.

In the embodiment of Fig. 3, the bearing block la is provided with a plug-in connection, which consists of a circumferential groove 7, in which the edge area of an opening 8 of a body wall 9 are fixed. Wiec \ -5r assumes that the inner, in diameter conically smaller part is smaller than the diameter of the opening 8, so that an easy plug-in assembly is possible from the attachment and insertion. Furthermore, a tab 10 is shown on one side, which is cut free from the body shell 9 and rests against the wall of the bearing block 1 a, whereby the stability, in particular the tight fit of the bearing block 1 a ₉ , is ensured.

This so-called harpoon connection is particularly favorable if apart from the loading of the rotor axis 2 or 2a cannot be precisely defined insertion depths are present, as is the case with a padding layer.
