Abstract

A seal includes a body and two lips. The body includes two walls defining a space with an opening. The lips have fixed ends respectively connected to the walls adjacent the opening. A movable end of the first lip is within the space. A movable end of the second lip extends across the opening towards the first lip fixed end. The movable end of the first lip includes a first end portion extending from the first lip fixed end along the first wall to a middle portion extending across the space to a second end portion extending along the second wall towards the second lip fixed end. The second end portion includes a hook section meeting the second wall and the second lip fixed end. The second lip movable end moves into the space and presses the hook section against the second wall to clamp the hook section.

Claims

1. A seal comprising:

a sealing body having first and second opposite side walls defining a portion of a receiving space having an opening;

a first sealing lip having a fixed end and a movable end, wherein the fixed end of the first sealing lip is connected to the first side wall of the sealing body adjacent to the opening and the movable end of the first sealing lip is within the receiving space; and

a second sealing lip having a fixed end and a movable end, wherein the fixed end of the second sealing lip is connected to the second side wall of the sealing body adjacent to the opening and the movable end of the second sealing lip extends across a portion of the opening towards the fixed end of the first sealing lip, wherein the first sealing lip is longer than the second sealing lip;

wherein the movable end of the first sealing lip includes a first end portion, a middle portion, a second end portion, and a U-shaped hook section, the first end portion extending from the fixed end of the first sealing lip away from the opening along the first side wall of the sealing body to the middle portion, the middle portion being disposed away from the opening and extending from the first end portion across the receiving space toward the second side wall of the sealing body to the second end portion, and the second end portion extending from the middle portion towards the fixed end of the second sealing lip;

the U-shaped hook section having a first leg, a middle segment, and a second leg, the first leg extending from the second end portion of the movable end of the first sealing lip towards the fixed end of the second sealing lip, the middle segment extending from the first leg towards the second side wall of the sealing body to the second leg and directly engaging the fixed end of the second sealing lip, and the second leg extending from the middle segment away from the opening along the second side wall of the sealing body;

wherein, in response to a window being inserted through the opening into the receiving space, the movable end of the second sealing lip moves into the receiving space and the first leg of the U-shaped hook section is moved towards the second side wall of the sealing body such that the second leg of the U-shaped hook section is pressed against and directly engages the second side wall of the sealing body whereby the U-shaped hook section is clamped in place between the fixed and movable ends of the second sealing lip and the second side wall of the sealing body.

2. The seal of claim 1 wherein:

the middle portion of the movable end of the first sealing lip is U-shaped.

3. The seal of claim 2 wherein:

the U-shaped middle portion is opened towards the opening.

4. The seal of claim 1 wherein:

the movable end of the first sealing lip includes a tapered wall section where the middle portion extends from the first end portion, wherein the tapered wall section forms a predetermined bending point.
