Automobile door sealing structure

An automobile door sealing structure comprising:

• a glass run mounted to a window frame defining a window opening of an automobile door to provide a seal between the window frame and a window glass;
• and
• a weather strip mounted to the window frame and located closer to a cabin than the glass run is, wherein
• the glass run includes an upper glass run portion extending in a front-rear direction of a vehicle along an upper frame portion of the window frame,
• the upper glass run portion includes a glass run body having an insertion groove into which a glass run mount of the upper frame portion is inserted,
• the glass run body includes an upper plate portion extending along an upper surface of the glass run mount, a lower plate portion extending along a lower surface of the glass run mount, and an exterior plate portion extending from an exterior end of the upper plate portion to an exterior end of the lower plate portion,
• the glass run body has a door panel sealing lip protruding downward from an interior end of the upper plate portion to contact the upper frame portion, the door panel sealing lip extending in the front-rear direction,
• the weather strip includes an upper weather strip extending in the front-rear direction along the upper frame portion, and mounted to a lower portion of a step part in the upper frame portion, the step part being located closer to the cabin than the glass run mount is, and having an exterior upper portion away from the cabin and an interior lower portion closer to the cabin,
• the upper weather strip includes a hollow seal part configured to elastically deform upon compression by a vehicle body and an outer sealing lip protruding upward from an exterior part of the hollow seal part to contact an interior end surface of the upper plate portion and an interior part of the door panel sealing lip of the glass run body,
• center portions of the upper weather strip and the upper glass run portion in the front-rear direction extend generally parallel to each other in the front-rear direction, and the upper weather strip extends downwardly away from the upper glass run portion in the front-rear direction to form a gap between the upper weather strip and the upper glass run portion, and
• the door panel sealing lip has a gradually varying portion with a protruding length or width substantially perpendicular to the upper plate portion, wherein the protruding length or width gradually increases toward an end of the door panel sealing lip in the front-rear direction starting from a position immediately before where the upper weather strip extends downwardly away from the upper glass run portion such that the gradually varying portion spans the gap to restrict water intrusion through the gap.
