Abstract

A sunroof seal assembly and method for a vehicle includes a sunroof frame disposed on the vehicle that defines a sunroof opening into which an associated sunroof panel is received, a first seal member mounted to the sunroof frame for sealing to an underside of a roof of the vehicle and a second seal member slideably mounted to the first seal member for sealing to the associated sunroof panel when the associated sunroof panel is in a closed position.

First claim

The invention claimed is:

1. A sunroof seal assembly for a vehicle, comprising:
a sunroof frame disposed on the vehicle that defines a sunroof opening into which an associated sunroof panel is received;
a first seal member mounted to the sunroof frame for sealing to an underside of a roof of the vehicle; and
a second seal member slideably mounted to the first seal member for sealing to the associated sunroof panel when the associated sunroof panel is in a closed position
wherein the second seal member slides onto and relative to the first seal member when a roof flange of the roof of the vehicle engages the second seal member and moves the second seal member relative to the first seal member during installation of the sunroof frame to the roof of the vehicle,
wherein the first seal member includes:
a sealing portion that seals against the underside of the roof of the vehicle,
a slideable mounting portion onto which the second seal member is slideable mounted,
a base portion from which the slideable mounting portion extends upward, and
a seal base portion from which the sealing portion extends upward, the seal base portion extends upward from the base portion in spaced relation relative to, and parallel with, the slideable mounting portion.

2. The sunroof seal assembly of claim 1 , wherein the first seal member further includes:
a frame mounting portion that fixes the first seal member to the sunroof frame.

3. The sunroof seal assembly of claim 1 , wherein the sealing portion is formed of a first material and the slideable mounting portion is formed of a second material, wherein the second material is more rigid than the first material, and wherein the first seal member is formed integrally as a unitary member.

4. The sunroof seal assembly of claim 1 , wherein the second seal member includes:
a U-shaped mounting channel that slideably receives the slideable mounting portion of the first seal member to slideably mount the second seal member onto the first seal member; and
a sunroof sealing portion that seals against the associated sunroof panel when the associated sunroof panel is in the closed position.

5. The sunroof seal assembly of claim 4 , wherein the second seal member further includes:
a flap-like roof sealing portion having a distal free end that extends away from the U-shaped mounting channel, the roof sealing portion seals against the roof flange of the roof of the vehicle, wherein the roof sealing portion is disposed on a roof side of the U-shaped mounting channel and the sunroof sealing portion is disposed on a sunroof side of the U-shaped mounting channel that is opposite the roof side.

6. The sunroof seal assembly of claim 5 , wherein the second seal member includes a shelf portion extending from the U-shaped mounting channel toward the roof, the shelf portion having an upper contact surface in abutment with a distal end of the roof flange, wherein said abutment by the distal end of the roof flange of the roof with the upper contact surface of the shelf portion of the second seal member slideably moves the second seal member relative to the first seal member such that the U-shaped mounting channel of the second seal member further seats onto the slideable mounting portion of the first seal member.

7. The sunroof seal assembly of claim 1 , wherein the first and second seal members define a flange recess into which the roof flange of the roof is received, the second seal member having a shelf portion with a contact surface that is engaged by the roof flange to move the second seal member slideably relative to the first seal member and further seat the second seal member relative to the first seal member.

8. The sunroof seal assembly of claim 7 , wherein the second seal member includes a bulbous sunroof sealing portion extending in a first direction away from the flange recess and toward the associated sunroof panel when the associated sunroof panel is in the closed position to seal against the associated sunroof panel and further includes a flap-like roof sealing portion extending in a second, opposite direction away from the flange recess toward the roof of the vehicle to seal against the roof flange of the roof.

9. The sunroof seal assembly of claim 7 , wherein a seal stiffener is embedded in the second seal member at the location of the shelf portion.

10. The sunroof seal assembly of claim 9 , wherein the seal stiffener extends around a U-shaped mounting channel of the second seal member that receives a slideable mounting portion of the first seal member.

11. The sunroof seal assembly of claim 7 , wherein the roof includes a roof stiffener and a roof skin, the roof skin wraps around the roof stiffener at the location of the distal end of the roof flange to form a hem.

12. A sunroof seal assembly method for a vehicle, comprising:
providing a sunroof frame disposed on the vehicle that defines a sunroof opening into which an associated sunroof panel is received when the associated sunroof panel is in a closed position;
mounting a first seal member to the sunroof frame for sealing to an underside of a roof of the vehicle; and
slideably mounting a second seal member to the first seal member for sealing to the associated sunroof panel when the associated sunroof panel is in the closed position installing the sunroof frame to the roof of the vehicle by inserting a roof flange of the roof into a flange recess adapted to receive the roof flange, wherein the roof flange engages the second seal member and moves the second seal member relative to the first seal member,
wherein the first seal member includes a slideable mounting portion and a sealing portion that seals against the underside of the roof of the vehicle,
wherein the second seal member includes a U-shaped mounting channel that slideably receives the slideable mounting portion of the first seal member and a flap-like roof sealing portion having a distal free end,
wherein the engagement of the roof flange with the second seal member moves the flap-like roof sealing portion into sealingly engagement with the U-shaped mounting channel.

13. The sunroof seal assembly method of claim 12 , further including:
slideably seating the second seal member onto the first seal member via the roof flange of the roof engaging and forcibly moving the second seal member.

14. The sunroof seal assembly of claim 13 , wherein the second seal member includes a shelf portion into which the roof flange engages to move the second seal member onto and relative to the first seal member.

15. The assembly of claim 11 , further comprising a dust sealer applied at the location of the roof flange and contacts a bottom surface of the roof stiffener.

16. The assembly of claim 12 , further comprising applying a dust sealer at the location of the roof flange and contacts a bottom surface of a roof stiffener.
