Abstract

A sealing system for an openable panel on a vehicle includes a channel member disposed on the openable panel and extending along a longitudinal axis and a seal member fastened to the channel member. The channel member includes two side portions extending parallel to each other and a recess defined between the two side portions. A plurality of depressions are defined in the side portions and extend along the longitudinal axis and into the recess. The seal member includes a proximal portion disposed within the recess and a distal portion extending away from the channel member. The proximal portion of the seal member has grooves defined on opposing sides thereof. The plurality of depressions on each side portion of the channel are received in a respective groove on the seal member to fasten the seal member to the channel member.

First claim

The invention claimed is:

1. A sealing system for an openable panel on a vehicle, the sealing system comprising:
a channel member configured to be disposed on the openable panel and extending along a longitudinal axis, the channel member comprising side portions extending substantially parallel to each other along the longitudinal axis and a recess defined between the side portions, the side portions each comprising a plurality of depressions defined therein extending along the longitudinal axis and into the recess of the channel member, the depressions arranged facing each other along the longitudinal axis; and
a seal member fastened to the channel member and extending along the longitudinal axis, the seal member comprising a proximal portion disposed within the recess of the channel member and a distal portion extending away from the channel member, the proximal portion of the seal member having grooves defined on opposite sides of the proximal portion and extending along the longitudinal axis, and the depressions on each of the side portions of the channel being received in corresponding grooves on the seal member to fasten the seal member to the channel member.

2. The sealing system according to claim 1 , wherein the plurality of depressions is formed in the side portions of the channel member by a punch and die.

3. The sealing system according to claim 1 , wherein each of the depressions comprises a straight section extending parallel to the side portion and two curved sections connecting the straight section to the side portion.

4. The sealing system according to claim 1 , wherein a depth and width of each of the depressions in the channel member is substantially the same as a depth and width of the respective groove in the seal member.

5. The sealing system according to claim 1 , wherein the depressions in each of the side portions of the channel member are spaced apart along the longitudinal axis.

6. The sealing system according to claim 1 , wherein the proximal portion of the seal member comprises a wedge.

7. The sealing system according to claim 6 , wherein the wedge comprises a cavity defined therein to facilitate insertion of the proximal portion of the seal member into the recess of the channel member.

8. The sealing system according to claim 1 , wherein the plurality of depressions is formed in the side portions of the channel member at positions configured to allow for connection of door skins to the channel member.

9. The sealing system according to claim 1 , wherein the channel member is a C-shaped channel member.

10. An openable panel for a vehicle, the panel comprising:
a rigid panel configured to be movably connected to a vehicle wall in an opening defined in the vehicle wall; and
a sealing system disposed on at least one side of the rigid panel, the sealing system comprising:
a channel member connected to the at least one side of the rigid panel and extending along a longitudinal axis, the channel member comprising side portions extending substantially parallel to each other along the longitudinal axis and a recess defined between the side portions, and
each of the side portions comprising a plurality of depressions defined therein extending along the longitudinal axis and into the recess of the channel member, the depressions arranged facing each other along the longitudinal axis; and

a seal member fastened to the channel member and extending along the longitudinal axis, the seal member comprising a proximal portion disposed within the recess of the channel member and a distal portion extending away from the channel member, the proximal portion of the seal member having grooves defined on opposite sides of the proximal portion and extending along the longitudinal axis,
the depressions on each of the side portions of the channel being received in corresponding grooves on the seal member to fasten the seal member to the channel member.

11. The openable panel according to claim 10 , wherein the rigid panel comprises a vehicle door panel.

12. The openable panel according to claim 10 , wherein each of the depressions comprises a straight section extending parallel to one of the side portions and curved sections connecting the straight section to the one of the side portions.

13. The openable panel according to claim 10 , wherein a depth and width of each of the depressions in the channel member is substantially the same as a depth and width of the respective groove in the seal member.

14. The openable panel according to claim 10 , wherein the depressions in each of the side portions of the channel member are spaced apart along the longitudinal axis.

15. The openable panel according to claim 10 , wherein the proximal portion of the seal member comprises a wedge.

16. The openable panel according to claim 15 , wherein the wedge comprises a cavity defined therein to facilitate insertion of the proximal portion of the seal member into the recess of the channel member.

17. The openable panel according to claim 10 , wherein the channel member is a C-shaped channel member.

18. A method for assembling the sealing system according to claim 1 , the method comprising:
providing the channel member;
forming the plurality of depressions in the side portions of the channel member by inwardly punching the side portions of the channel member at a plurality of locations along the longitudinal axis; and
inserting the proximal portion of the seal member into the recess of the channel member such that the plurality of depressions engages the grooves in the opposite sides of the seal member.

19. The method according to claim 18 , further comprising bending the channel member to obtain a curvature corresponding to a curved edge of the openable panel.

20. The method according to claim 18 , wherein the depressions are formed with a width and depth equal to a width and depth of the grooves in the seal member.
