Vehicle weather strip for liquid drainage and prevention of liquid intrusion into vehicle interior
A weather strip for a vehicle door includes a flow channel extending along at least a portion of the weather strip. A discharge portion is in fluid communication with the flow channel and is structured to enable a liquid to flow therealong from the flow channel to a location outside the flow channel. An end wall extends from a first side of the flow channel and is positioned to direct a liquid impinging on the end wall from the flow channel toward the discharge portion.
1. A weather strip for a vehicle door, the weather strip comprising:
a flow channel extending along at least a portion of the weather strip;
a discharge portion including a through-hole formed along the flow channel and structured to enable a liquid to flow therealong from the flow channel to a location outside the flow channel, the through-hole being structured to direct at least a portion of the liquid along a forward face of the discharge portion; and
an end wall extending from a first side of the flow channel and defining an edge of the through-hole, the end wall being positioned to direct a liquid impinging on the end wall from the flow channel toward the through-hole,
wherein the discharge portion forward face is structured so that liquid reaching an end of the discharge portion forward face flows onto a first portion of the weather strip extending along a forward edge of the vehicle door and then further downwardly along the first portion of the weather strip.
2. The weather strip of claim 1 , wherein the through-hole is structured to discharge a liquid from the flow channel through a passage formed between a side of the flow channel and the end wall.
3. The weather strip of claim 1 , wherein the discharge portion comprises a ramp portion extending from the flow channel and the through-hole, the ramp portion being structured to guide a flow of liquid away from the flow channel.
4. The weather strip of claim 1 , wherein the through-hole is bounded on all sides by other portions of the weather strip.
5. A vehicle door comprising:
an upper edge; and
a weather strip in accordance with claim 1 and having a portion extending along the door adjacent the door upper edge and including the flow channel.
6. The vehicle door of claim 5 , wherein the door includes:
a rear edge extending from the door upper edge; and
a forward edge extending from the door upper edge opposite the door rear edge,
and wherein the portion of the weather strip extending along the door adjacent the door upper edge is mounted to the door so as to slope downwardly in a direction extending from the door rear edge toward the door forward edge when the door is mounted on a vehicle and is completely closed.
7. The vehicle door of claim 6 , wherein the door upper edge is structured so as to slope downwardly in a direction extending from the door rear edge toward the door forward edge, when the door mounted on a vehicle and is at least partially open.
8. The vehicle door of claim 5 , wherein the weather strip is structured and attached to the door so as to cause a liquid in the flow channel to flow along the flow channel while the door is in completely closed.
9. The vehicle door of claim 5 , further comprising a side wall extending from a side of the flow channel and structured to seal against a portion of a body of the vehicle when the door is completely closed.
10. A weather strip for a vehicle door, the weather strip comprising:
a flow channel extending along at least a portion of the weather strip;
an end wall extending from a first side of the flow channel;
a discharge portion including a notch formed in the end wall, wherein the end wall and the flow channel are structured to direct a flow of liquid from the flow channel through the notch to a location outside the flow channel, the discharge portion being structured to direct at least a portion of the liquid along a forward face of the discharge portion so that liquid reaching an end of the forward face flows onto a first portion of the weather strip extending along a forward edge of the vehicle door and then further downwardly along the first portion of the weather strip.
11. The weather strip of claim 10 , further comprising a side wall extending from a side of the flow channel and intersecting the end wall.
12. The weather strip of claim 11 , wherein the flow channel is structured to curve in a direction away from the side wall as the flow channel extends toward the end wall.
13. A vehicle door comprising a weather strip in accordance with claim 5 , wherein the discharge portion is structured to discharge a flow of liquid from the flow channel at a location forward of a forward edge of a panel of the door.
