SEALING PROFILE FOR SEALING A PANEL ELEMENT IN A STRUCTURE, IN PARTICULAR FOR SEALING A PANE IN A MOTOR VEHICLE BODYWORK

Abstract

In a sealing profile for sealing a panel element in a structure, in particular for sealing a pane in a motor vehicle bodywork, comprising an attachment region for attachment to the structure, wherein the attachment region has a reinforcement profile with at least one decorative region openly visible to the exterior, and at least one sealing region, provision is made such that the reinforcement profile is constituted by a thin metal material and at least one rigid plastic material, wherein the plastic material is extruded onto the metal material and wherein the metal material comprises the decorative region.

Claims

1. A sealing profile for sealing a panel element in a structure, in particular for sealing a pane in a motor vehicle bodywork, comprising an attachment region for attachment to the structure, wherein the attachment region has a reinforcement profile with at least one decorative region openly visible to the exterior, and at least one sealing region, wherein the reinforcement profile is constituted by a thin metal material and at least one rigid plastic material, wherein the plastic material is extruded onto the metal material and wherein the metal material comprises the decorative region.

2. The sealing profile according to claim 1, wherein the metal material is a thin sheet with a thickness of approximately 0.2 to 0.4 mm.

3. The sealing profile according to claim 1, wherein the metal material has a U-shape, wherein an outer side of a U-leg is constituted as the decorative region and the extruded-on rigid plastic material is applied at the inner sides of a the U-base and U-legs.

4. The sealing profile according to claim 1, wherein the extruded-on rigid plastic material is PP.

5. The sealing profile according to claim 1, wherein a non-rigid plastic material for forming the sealing region is additionally extruded onto the thin metal material and onto the extruded-on rigid plastic material.

6. The sealing profile according to claim 5, wherein sealing lips are formed with the non-rigid plastic material.

7. The sealing profile according to claim 5, wherein the decorative region of the metal material openly visible to the exterior is coated with the extruded-on non-rigid plastic material.

8. The sealing profile according to claim 5, wherein a primer is applied on sections of the thin metal material and of the rigid plastic material before the extruding-on of the non-rigid plastic material.

9. The sealing profile according to claim 5, wherein the non-rigid plastic material is an EPDM.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] An example of embodiment, from which further inventive features emerge, is represented in the drawing. In the figures:

[0018] FIG. 1: shows a sealing profile according to the invention during its fitting on the flange of a motor vehicle bodywork and

[0019] FIG. 2: shows the sealing profile according to FIG. 1 during its use.

DETAILED DESCRIPTION

[0020] FIG. 1 shows a flange 1 of a motor vehicle bodywork, towards which a glass pane 2 is to be brought up close. The transition between flange 1 and glass pane 2 is ensured by the sealing profile according to the invention, for which purpose the latter is fixed to flange 1.

[0021] For the fastening of the sealing profile, attachment region 3 with the sealing profile is placed on flange 1. Attachment region 3 comprises a reinforcement profile 4 constituted U-shaped. According to the invention, reinforcement profile 4 is constituted by a thin metal material 5 and a rigid plastic material 6 extruded onto metal material 5. Rigid plastic material 6 is arranged at the inner sides of the U-legs and the U-base of reinforcement profile 4. Rigid plastic material 5 forms, with the aid of a protrusion 7, an end stop for the fitting of the sealing profile on bodywork flange 1.

[0022] A non-rigid plastic material 8 is arranged on the outer side of reinforcement profile 4. Said non-rigid plastic material is extruded onto metal material 5 and onto rigid plastic material 6, it covers the outer side of reinforcement profile 4 and also forms sealing lips 9. The latter are applied against various sections of bodywork flange 1 or against glass pane 2. Sealing lip 9, for its application on glass pane 2, is also coated with a flock material 10, which improves the slidability of pane 2 along non-rigid plastic material 8.

[0023] FIG. 2 shows the sealing profile with the formation of a decorative region 11 visible to the exterior. This decorative region 11 is constituted by thin metal material 5 by sections at the outer side of a U-leg of reinforcement profile 4. Non-rigid plastic material 8 is removed in this region. In other regions, non-rigid plastic material 8 adheres to thin metal material 5 or to rigid plastic material 6, preferably by using a primer between these materials.
