Abstract

A taped seal construction for a body part of a vehicle, with a seal with a main portion and a lip portion, the main portion being designed to extend on one side of the body part of the vehicle and the lip portion being designed to extend on another side of the body part of the vehicle thereby covering an edge of the body part, and a tape, the tape being attached to the main portion of the seal, wherein that the tape comprises a split liner.

First claim

The invention claimed is:

1. Taped seal construction for a body part of a vehicle, comprising
a seal with a main portion and a lip portion, the main portion being designed to extend on one side of the body part of the vehicle and the lip portion being designed to extend on another side of the body part of the vehicle thereby covering an edge of the body part, and
an adhesive tape attached to the main portion of the seal, with the tape comprising an adhesive covered by a split liner having a first liner part and a second liner part that are split such that the first liner part has a smaller width than the second liner part, in a cross sectional view perpendicular to the direction of the longitudinal extension of the taped seal construction, wherein the first liner part of the split liner is closer to the lip portion of the seal than the second liner part.

2. Taped seal construction according to claim 1 , wherein the seal is made out of ethylene-propylene copolymers, ethylene propylene-diene terpolymers and/or styrene-butadiene copolymers.

3. Taped seal construction according to claim 1 , wherein the tape comprises a heat-activatable adhesive layer and a pressure-sensitive adhesive layer, wherein the heat-activatable adhesive layer faces the main portion of the seal.

4. Taped seal construction according to claim 3 , wherein the heat-activatable adhesive layer is a resin layer, wherein the resin is a polymer of one or more monomers selected from the group consisting of olefins.

5. Taped seal construction according to claim 3 , wherein the pressure-sensitive adhesive layer comprises an acrylic-type pressure sensitive adhesive.

6. Taped seal construction according to claim 1 , wherein the lip portion covers the tape with the liner thereby enclosing a space with an opening.

7. Taped seal construction according to claim 1 , wherein the lip portion extends in a direction essentially perpendicular to the tape.

8. Taped seal construction according to claim 1 , wherein the liner is completely split such that the liner consists of at least two parts.

9. Taped seal construction according to claim 1 , wherein the liner is split along the direction of the longitudinal extension of the taped seal construction.

10. Method of applying a taped seal construction according to claim 1 to a body part of a vehicle, the method comprising:
removing the first liner part of the liner,
applying the taped seal construction to the body part of the vehicle with that portion of the tape that was covered by the first liner part of the liner,
checking the position of the taped seal construction,
correcting the position of the taped seal construction, if necessary,
removing the second liner part of the liner and
applying the taped seal construction to the body part of the vehicle with that portion of the tape that was covered by the second liner part of the liner.

11. Motor vehicle comprising a taped seal construction according to claim 1 .

12. Taped seal construction according to claim 2 , wherein the tape comprises a heat-activatable adhesive layer and a pressure-sensitive adhesive layer, wherein the heat-activatable adhesive layer faces the main portion of the seal.

13. Taped seal construction according to claim 3 , wherein the lip portion covers the tape with the liner thereby enclosing a space with an opening.

14. Taped seal construction according to claim 8 , wherein the lip portion extends in a direction essentially perpendicular to the tape.

15. Taped seal construction according to claim 6 , wherein the liner is completely split such that the liner consists of at least two parts.

16. Taped seal construction according to claim 13 , wherein the liner is completely split such that the liner consists of at least two parts.

17. Taped seal construction according to claim 14 , wherein the liner is completely split such that the liner consists of at least two parts.

18. Taped seal construction according to claim 8 , wherein the liner is split along the direction of the longitudinal extension of the taped seal construction.

19. Taped seal construction according to claim 15 , wherein the liner is split along the direction of the longitudinal extension of the taped seal construction.
