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

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 a tape, the tape being attached to the main portion of the seal,
characterized in that the tape comprises a split liner.

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 or 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.

4 . Taped seal construction according to any one of the preceding claims, 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 any one of the preceding claims, wherein the pressure-sensitive adhesive layer comprises an acrylic-type pressure sensitive adhesive.

6 . Taped seal construction according to any one of the preceding claims, wherein the lip portion covers the tape with the liner thereby enclosing a space with an opening.

7 . Taped seal construction according to any one of the claims 1 to 5 , wherein the lip portion extends in a direction essentially perpendicular to the tape.

8 . Taped seal construction according to any one of the preceding claims, wherein the liner is completely split such that the liner consists of at least two parts.

9 . Taped seal construction according to any one of the preceding claims, wherein the liner is split along the direction of the longitudinal extension of the taped seal construction.

10 . Taped seal construction according to any one of the preceding claims, wherein the liner is split such that the two liner parts have different widths in a cross sectional view perpendicular to the direction of the longitudinal extension of the taped seal construction.

11 . Method of applying a taped seal construction to a body part of a vehicle, the taped seal construction comprising a seal and a tape, wherein the tape comprises a split liner consisting of at least two parts, the method comprising the following steps:
removing a first 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 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 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 part of the liner.

12 . Method of applying a taped seal construction according to any one of the claims 1 to 10 to a body part of a vehicle, the method comprising the following steps:
removing a first 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 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 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 part of the liner.

13 . Motor vehicle comprising a taped seal construction according to any one of the claims 1 to 10 .
