## Abstract

A flush glass window seal for motor vehicle windows having a substantially rigid, dual durometer thermoplastic elastomer, carrier component and a resilient elastomer, sealing insert which are mechanically locked together. The carrier components are extruded or molded in one piece to conform to the generally U-shaped vehicle opening and the insert is extruded in a generally flat configuration suitable for application of a slip surface thereon, prior to its insertion into the carrier.

## Claims

### Claim 1

A method for assembling a flush glass window seal comprising:
coextruding thermoplastic elastomers of different durometer values to form a substantially rigid, dual durometer thermoplastic elastomer carrier in a one-piece, generally U-shaped configuration for receiving a resilient insert;
extruding a generally fiat, resilient insert for said thermoplastic elastomer carrier;
folding said resilient insert into a generally U-shaped configuration; and
pressing said folded insert into the carrier to mechanically secure the insert to the carrier.

### Claim 2 (depends on 1)

The method according to claim 1 further comprising flocking the generally fiat, resilient insert.

### Claim 3 (depends on 1)

The method according to claim 1 further comprising curing of the extruded, resilient insert.

### Claim 4

A method for assembling a flush glass window seal comprising:
molding thermoplastic elastomers of different durometer values to form a substantially rigid, dual durometer thermoplastic elastomer carrier in a one-piece, generally U-shaped configuration for receiving a resilient insert;
extruding a generally flat, resilient insert for .said thermoplastic elastomer carrier;
folding said resilient insert into a generally U-shaped configuration; and
pressing said folded insert into the carrier to mechanically secure the insert to the carrier.

### Claim 5 (depends on 4)

The method according to claim 4 further comprising flocking the generally fiat, resilient insert.

### Claim 6 (depends on 4)

The method according to claim 4 further comprising curing of the extruded, resilient insert.
