Description

[Detailed description of the invention] automotive sun visor The present invention relates to a sun visor for a motor vehicle having a rectangular plate of plastic material.

For safety reasons, modern car sun visors are made of relatively It has a plate of soft material or a hollow plate of non-foamed plastic. This thing is Sun visors to absorb shock from the occupants in the event of a collision or sudden braking. It gives compressibility to.

In either case, the plate is aesthetically pleasing, usually suitable for sun visors inside automobiles. Covered by a plastic film that helps give the look. on the board A commonly used method for installing film is to place a sheet of film on both sides of the board. Install, weld a sheet of film around both edges of the board and remove excess film. This includes trimming the film material outside the weld line.

Sun visors are manufactured in very large numbers and therefore can be done to keep prices low. It is only important to significantly automate the manufacturing process. However, the film Installation is difficult to perform completely without manual labor.

The object of the invention is to enable the manufacture of plates without the need to attach a surface layer on the side after manufacture. By providing a sun visor with a rectangular plate of plastic material constructed be.

This means that, according to the invention, the surface has the final shape and surface structure of the plate. This is achieved by a plate made of plastic elastomer.

The present invention is based on a method of manufacturing conventional sun visors; A process consisting of a durable backing of one material and a soft surface layer of another material attached to it. Based on the idea of abandoning the idea, instead, the sun visor was manufactured from a single material and the method combines the properties of traditionally used materials in the backing and surface layers as much as possible. Ru. Therefore, it is possible to achieve the desired properties by using thermoplastic elastomers. That's what I found out. These materials combine the flexibility of rubber with the strength of structural plastics. Sun visor through regular blow molding or injection molding technology for example can be used in the manufacture of sun visor panels with a final surface structure The whole can be manufactured in a single step.

Reference will now be made in more detail to the embodiments illustrated in the accompanying drawings.

FIG. 1 shows an exploded view of a sun visor plate consisting of two arms.

Section 2 shows a cross-sectional view through the plate of FIG. 1 with the circled area enlarged separately.

The sun visor plate shown in FIG. and their opposite sides are mirror symmetrical. Inside each of them is a plate half 1, 2 is provided with reinforcing ribs 3 and 4 extending vertically and horizontally, respectively. They form a stiffened frame around the unreinforced recess 5. Board half part 1 ．． 2 is a first notch 6 for the main pivot pin (not shown) and a second notch 6 (not shown). A notch 7 for a pivotable bin is formed.

A laterally extending rib 4a revealing a semicircular notch 8 for the main mounting bin extends longitudinally. with a snap-in retaining spring (not shown) for the main bearing. A box or pocket 9 is defined. The wall portion 10 facing the cutout 7 has a second A semicircular notch 11 for a pivotable bin is formed.

FIG. 2 shows that the complete sun visor panel has been removed, e.g. by sticking or welding. and 2 are shown in cross-sectional view after being glued together. As is clear from the drawing, the board is simply It consists of one material layer 20. The material is a thermoplastic elastomer, such as Hytre This material is commercially available under the registered trade name HYTREL. The material layer 20 is the back side It forms a support unit, the surface 21 of which forms the surface of a sun visor. Itahan The parts can be injection molded from materials containing colored pigments, thereby enhancing the internal structure of the vehicle. It is possible to provide a surface structure suitable for construction. The surface may be a textile surface or a leather surface, for example. It can be configured to resemble a surface. Such sun visors are made of PvC film Thus it looks and feels like a regular sun visor made from covered foam. It can be configured so that it is the same. The recess 5 between the halves l and 2 is give it the necessary compressibility. The elasticity of the material and therefore the compressibility of the sun visor board is determined by the It is determined by the thickness of layer 2o. The thickness of the plate layer can be up to 3 mm .

For the injection molding and subsequent joining of the two plate halves, for example by gluing or welding. Alternatively, blow molding or gas injection can be used, thereby The board can be manufactured in one piece.
