DE19834999A1 - Sun shield used in road vehicle - Google Patents

Abstract

The vehicle sunshield is encapsulated between two covering films (5a,5b), bonded together. The shield has a netting core (2) between two plates (4a,4b) of soft plastics foam. At least one stiff board (3a,3b) is between the core and one of the foam plates, so that the netting structure shape is not detected on touching. The stiff boards are made of polyethylene, polypropylene, polyamide, polyvinyl chloride (PVC) or with a content of additives with molecules which oscillate when subjected to an alternating voltage to generate heat (TPO material). Alternatively the boards are made of natural materials such as cardboard, cork or a wood lamination.

Description

The invention relates to a sun visor for cars, which has an aperture arranged between two cover foils, the cover foils ver with each other around the panel are bound and the aperture is a mesh-like insert made of plastic, which is between two plates of egg nem soft foam is arranged.  

The mesh-like insert is in the middle plane of the son arranged and ensures the rigidity of the Blen de. It includes means by which a bearing for a curved th support arm can be rotatably accommodated, which on Upper part of the body of the vehicle is attached, and Means that the sun visor on one with the top connected hook can be hooked.

The cover films are often made of PVC and are welded to the peripheral wall of the panel.

The panels are generally made of polyethylene foam manufactured. The main job of these plates is heavy Injuries in the event of a blow through the head of a pas to prevent sagiers in an accident and a pleasant one Ensure grip.

The main disadvantage of this technology is that the user the shapes of the plastic insert when touched through the cover foils and the soft plastic foam can feel by.

The object of the invention is to overcome this disadvantage.

The aim of the invention is achieved in that the Son nenblende also at least one rigid panel element has, which between the insert and one of the Foam sheets is arranged.

It preferably comprises two rigid panel elements, which each between the insert and one of the foam plates are arranged.

The rigid panel elements are e.g. B. made of plastic such as made of polyethylene, polypropylene or Polyamide, or of non-plastic, such as. B. from cardboard,  Cork or "Woodstock", the latter also for. B. Holzfour nier includes.

According to a preferred embodiment, this becomes rigid Panel element when forming the net-like insert on egg ne molded from the end faces.

Due to the invention, the farms of the insert can no longer be felt when touched. So it is now possible the distances between the ribs of the netzarti gene insert, which means less material for the insert is required.

Further advantages and properties of the invention are described with With the help of the following exemplary description and with Be train clearly on the attached drawing, in which the one Zige figure is an exploded view of a structure represents sun visor according to the invention.

The drawing shows an exploded view of a sun visor 1 , which has a mesh-like insert 2 . This is arranged in the manner of a sandwich between two cushioning plates 4 a, 4 b made of foam, the outer sides of which are covered by two cover foils 5 a, 5 b. These cover films 5 a, 5 b are then connected to each other around the net-like laying part 2 .

Between the upholstery panels 4 a, 4 b and the mesh-like insert 2 , two rigid panel elements 3 a, 3 b are also provided.

The mesh-like insert 2 is produced by injecting a plastic into a suitable shape. It comprises a peripheral wall 10 and a plurality of cross-shaped ribs 11 , through which cells 12 define who who open into the opposite end faces of the insert 2 . It also includes means by which a bearing for a curved arm (not shown in the drawing) is fixed in the direction of rotation and with which a support arm can be attached, which cooperates with a hook that attaches to the upper part of the body of the vehicle which is equipped with the sun visor.

The rigid board elements 3 a, 3 b have a small thickness. You can be made of a rigid plastic, such as. B. made of polyethylene, polypropylene or polyamide. They can also be made of a non-plastic material, such as cardboard, cork or "Woodstock", where the latter also contains e.g. B. includes wooden veneer. These Tafelele elements made of plastic have the task that the shapes of the mesh-like insert 2 can not be erta Stead at a touch. As a result, the distances between the ribs 11 can be increased, thereby saving material in the insert 2 is achieved.

In the case in which the sun visor according to the invention has only one rigid panel element 3 on one of the end faces of the mesh-like insert 2 , this rigid panel element 3 can be connected to the insert 2 and in the form of a cover on one of the end faces of the insert 2 during injection molding of the insert 2 are produced.

In this case, the cells 12 are only open on the side opposite the cover.

The padding plates 4 a, 4 b are made in a conventional manner from a soft plastic foam.

The cover films 5 a, 5 b can be drawn from PVC sheets. In this case, they are welded together around the circumferential wall 10 of the mesh-like insert 2 .

To assemble the sun visor, the individual sandwich components are arranged in a suitable two-part form, which has means with which the cover foils 5 a, 5 b can be connected to one another, for example by welding, and which means with which the parts the cover films 5 a, 5 b can be cut off, which are located outside the weld.

In order to prevent the person to sammenbaut the sun visor 1, is required to handle numerous components, the rigid panel members 3 a can 3 b above with the reticulated A fixing part 2 or the padding plates 4 a, 4 b of soft foam, for example by Bonded together.

In the same way, the cover films 5 a, 5 b can be connected beforehand to the padding plates, for example by gluing or welding.

The rigid panel elements 3 a, 3 b can Sieren polypropylene ba and comprise polarized additives which make them during welding in a high frequency electric field ther mixed sensitive. The alternating voltage causes the molecules of the additives in oscillation, thereby they heat up and thus heat the material from which the Ta felelemente 3 a, 3 b are formed. This type of material is known under the name TPO.

With this type of material, the sheet elements 3 a, 3 b are preferably welded together at the edge of the mesh-like insert 2 and cut off outside the weld seam in the form of the last step of assembling the sun visor.

The cover films 5 a, 5 b can also be produced with the same material on the basis of polypropylene, which has polarized additives. In this case, the rigid panel elements 3 a, 3 b and the cover foils 5 a, 5 b can be connected to one another by welding in the last step of the assembly.

If the plates are made of foam with a material Herge, which is compatible with the material from which the rigid panel elements 3 a, 3 b and the cover sheets 5 a, 5 b are made, all these components can mitein other during the last step of the assembly are welded.
