Abstract

A vehicle sealing system includes an outer sash molding component, an inner sash trim component, a first seal, and first, second and third seal members. The outer sash molding component covers a first portion of a door frame member. The inner sash trim component covers a second portion of the door frame member. The first seal is co-extruded with the outer sash molding component. The first seal member is dual shot molded with the inner sash trim component. The second seal member is co-extruded with the outer sash molding component. An end of the outer sash molding component is embedded in the second seal member. The third seal member forms a cushion between the glass and the door frame member. The seal members are spaced apart from each other and coupled to one of the outer sash molding component and the inner sash trim component separately from each other.

Claims

1. A vehicle sealing system, comprising:

a door frame member including a generally U-shaped cavity formed therein for receiving glass from a window;

an outer sash molding component covering a first portion of the door frame member;

an inner sash trim component covering a second portion of the door frame member;

a first seal including a flexible seal member co-extruded with the outer sash molding component;

and

first, second, and third seal members provided in or on the generally U-shaped cavity formed in the door frame member, wherein;

the first seal member is dual shot molded together with the inner sash trim component,

the second seal member is co-extruded with the outer sash molding component such that an end of the outer sash molding component is embedded in the second seal member, the first and second seal members being inwardly rotatable upon receiving a biasing force from upward movement of the glass, and

the third seal member is provided on a base of the generally U-shaped cavity so as to form a cushion between the glass and the door frame member,

wherein the first, second and third seal members are non-integrally formed with each other and spaced apart from each other such that the first seal member is directly attached to the inner sash trim component and is individually coupled to the inner sash trim component separately from the second and third seal members, the second seal member is directly attached to the outer sash molding component and is individually coupled to the outer sash molding component separately from the first and third seal members, and the third seal member is directly attached to the base of the generally U-shaped cavity and is individually coupled to the base of the generally U-shaped cavity separately from the first and second seal members.

2. The vehicle sealing system of claim 1, wherein the second seal member forms a glass run seal, and the flexible seal member of the first seal forms a margin seal, wherein the glass run seal and the margin seal integrated into the outer sash molding component.

3. The vehicle sealing system of claim 2, wherein the first seal member forms another glass run seal.

4. The vehicle sealing system of claim 1, wherein the first seal member forms a glass run seal.

5. The vehicle sealing system of claim 1, wherein the sash molding component comprises roll-formed stainless steel or roll-formed aluminum.

6. The vehicle sealing system of claim 1, wherein the flexible seal member of the first seal comprises EPDM or TPE.

7. The vehicle sealing system of claim 1, wherein the first seal member comprises TPE.

8. The vehicle sealing system of claim 1, further comprising a fourth seal member located on an inner leg of the generally U-shaped cavity, the fourth seal member forming a cushion between the first seal member and the inner leg of the cavity.

9. A vehicle door comprising a sealing system, comprising:

a door frame member including a generally U-shaped cavity formed therein for receiving glass from a window, the door frame member comprising a roll-formed outer structure and a stamped inner structure;

a roll-formed outer sash molding component provided at an exterior portion of the vehicle door;

an inner sash trim component provided at an interior portion of the vehicle door; and

first, second, and third seal members provided in or on the generally U-shaped cavity formed in the door frame member, wherein;

the first seal member is dual shot molded together with the inner sash trim component,

the second seal member is co-extruded with the outer sash molding component such that an end of the outer sash molding component is embedded in the second seal member, the first and second seal members being inwardly rotatable upon receiving a biasing force from upward movement of the glass, and

the third seal member is provided on a base of the generally U-shaped cavity so as to form a cushion between the glass and the door frame member,

wherein the first, second and third seal members are non-integrally formed with each other and spaced apart from each other such that the first seal member is directly attached to the inner sash trim component and is individually coupled to the inner sash trim component separately from the second and third seal members, the second seal member is directly attached to the outer sash molding component and is individually coupled to the outer sash molding component separately from the first and third seal members, and the third seal member is directly attached to the base of the generally U-shaped cavity and is individually coupled to the base of the generally U-shaped cavity separately from the first and second seal members.

10. The vehicle door of claim 9, further comprising a first seal proximate to an exterior of the sealing system, the first seal including a flexible seal member co-extruded with the outer sash molding component.

11. The vehicle door of claim 10, wherein:

the second seal member forms an outer glass run seal, and the flexible seal member of the first seal forms a margin seal, wherein the glass run seal and the margin seal are integrated into the outer sash molding component, and

the first seal member forms an inner glass run seal.

12. The vehicle door of claim 9, further comprising a fourth seal member located on an inner leg of the generally U-shaped cavity, the fourth seal member forming a cushion between the first seal member and the inner leg of the cavity.

13. A vehicle comprising the vehicle door according to claim 9.
