Description

It has long been customary in the automotive industry to equip passenger vehicles with a so-called car headliner. This generally introduced word designates the roof covering in the interior of the body in an elaborate and time-consuming way, for example how "d" so-called clipping is attached to the roof of the car . otherwise it forms wrinkles

Thereby arises between the actual Iu odach and heaven always οΐπ, cavity, especially since any textile keteching is always very thin

These disadvantages of the state of the art are more likely to be present Innovation surmounted by a car horn, the progressive-wise Much easier to manufacture and much safer and faster to assemble 1st «In further progress

the innovation according to the car dealership consists in the fact that it has a shown upholstery effect, a wall insulation as well as a Exerts soundproofing effect, i.e. it comes with the new headliner the safety within the vehicle for the vehicle occupants significantly increased.

The essence of the present innovation is explained in detail with reference to the enclosed Figures 1 to 3.

Figure 1 shows an embodiment of the innovation according to the headliner in a perspective view.

FIG. 2 shows a perspective illustration of a special type of execution of a rear corner of the innovation according to the invention Car heaven.

Figure 3 shows a perspective view of a special type of execution of the front corner of the car headliner.

The car headliner according to the innovation is marked daduroh that it consists of a rigid foam sheet that is deformed using higher temperatures, the Faohmann using this type of deformation looking at the finished sky

According to a preferred design, Eich builds the new one Car roof made of a hard layer, but something else flexible polyurethane foam with a synthetic leather or any other foil or textile material is cached

The enclosed figures show the finished headliner with the Reference number 1, the foam with the reference number la and

- Sheet 3 denotes the lamination with the reference number 2.

The front corner Id of Figure 1 is in Figure 3 and the back

1 c
toe corner of Figure 1 in Figure 2 drawn out again.

You can especially see the deformation here.

To produce the headliner according to the innovation is now as follows

The rigid foam made of polyurethane foam is cut into panels 5 - 20 mm thick and these panels are laminated with the selected covering material. Now, the Hartsohaumplatte with hot air of 120 ° is - 250 ⁰ C, preferably ⁰ I50 -, warmed 200 ⁰ C by inflating and deformed by pressing in a suitably shaped mold, the enteprioht the contours of the desired Himmele. In contrast to the deformation of the cold foam, the deformation that occurs here is irreversible. A self-supporting headliner is thus obtained through a rreßVorgang, which can be easily attached to the inside of the car roof, for example by gluing.

Of course, it is also possible to use the rigid foam board eret au deform and then conceal, but this is The way of working is more laborious and time-consuming, especially with a complicated shape or more pronounced curvature.

The mold itself can be heated, but this is not absolutely necessary «

It usually needs a prolonged contact at temperatures above 200 ° C, otherwise discoloration or embrittlement of the foam can occur
