Definitions
- a paint protection method for preferably thinner components consists of adhering the paint-free-holding area with a film or a label, which is not reusable, but can be removed after the painting process. Many attempts focus on the selection of a suitable adhesive, which has reliable sealing adhesive properties and can be easily and quickly removed after the painting process.
- a serious problem in this case is the drying process after the application of the paint.
- This has the effect that not only the properties of the freshly applied paint are affected, but also that of the adhesive, with the result that the labels are not removable without residue after the drying step or, if substances are used with a lower adhesive strength from the outset, even during painting have detachments, which lead to an undesirable underrun of Lackiertikes.
- gluing rounded parts with low radii occurring due to the curvature in the label material tension requires compared to flat paint protection areas increased adhesive force of the adhesive used.
- the first apparent use of silicone-containing release coatings proves to be problematic because sometimes released silicone the Delicate annoying paint process and can cause painting defects (see Offenlegungsschrift DE 102 03 235 A1 ).
- Lackier attacksetiketten Another problem with the use of Lackierschutzetiketten is that they must have adapted to the temperatures of the drying step in the painting process heat resistance. Metallic vapor-deposited labels are used, whose heat-reflecting properties are exploited. The production of such labels is more costly, time consuming and costly than the production of single-layer labels.
- paint protection labels are currently being used in many areas, they are mainly used to protect simple textured areas and quickly find their limitations when it comes to protecting more complex moldings from painting.
- thermoplastic material which is injection-suitable and encases the area to be protected.
- the sheath is formed at least at one point as a complete, tight enclosure of the molding used and thus ensures sufficient material tension. Without at least one point at which the casing completely surrounds the molded part used, only an attachable partial casing would be provided, which only in exceptional cases would have the required sealing properties compared to the lacquers used in automotive finishes.
- the sheath has at least one weakened zone, in which the thermoplastic material can be separated under the action of tensile, shear, rotational, compressive, compressive or tensile forces.
- the weakening zone can be defined by one or more material recesses, wherein a material recess is understood to mean a hole extending through the entire material thickness, as in the case of perforated materials. It is also possible to cause the weakening of the material only by one or more recesses, wherein a recess is understood as not passing through the entire material thickness trough.
- the ISOFIX mechanism consists on the child's seat side of two locking arms with snap closures, which engage around two complementary locking bracket (6), which in turn are attached to the vehicle structure between the seat back and seat.
- the locking brackets of the ISOFIX system protrude between seat back and seat out, so that they are permanently visible in the passenger compartment with removed child seat. Since the locking bracket (6) in the case of non-replaceable seats and backbanks are firmly welded to body parts, they are subject to the above-described painting. A painting of the visible areas of the locking clip is undesirable. Due to frequent engagement and disengagement of the ISOFIX child seats, the paint layer is damaged and unsightly within a very short time. The solution to the problem here is to remove the stainless steel latch (6) at the points where they are visible, the painting process.
- the paint protection according to the invention is used: By injection molding suitable plastic of good flexibility and toughness at high and low temperatures, which should have a good resistance to oil and aliphatic or aromatic solvents, injected directly around the locking bracket (6).
- Proven here is the thermoplastic polyester elastomer Hytrel® G4774.
- a uniform sheathing of the horizontally extending to the seat edge portion of the locking clip (6) would not be effective, since although the desired paint protection would be achieved, the removal of a so-formed Lackier attackses would be too time-consuming and could not succeed without special tools.
- a targeted material recess (5) in the injection molding a weakening zone (3) of the casing, so that only two places complete enclosures (2) of the latching clip (6) remain, the required material tension maintained.
- the material recess (5) is here the rear end, the seat upholstery facing area of the locking bracket (6), which is selected in positioning and expansion so that it is no longer visible in its final arrangement between the seat back and car seat surface.
- Has proven to be suitable has a rectangular material recess (5) with a ratio of width to height of about 16 to one.
