Abstract

A seal for an automobile door includes a glass run and a belt line inner seal. The glass run has a vertical portion which includes a vertical seal lip, and the belt line inner seal includes an upper belt line seal lip and a lower belt line seal lip. The vertical seal lip is integral and unitary with ends of the upper and lower belt line seal lips, and the vertical portion includes a A-divider wall portion extending vertically and protruding toward the outside of a cabin of the automobile between the upper and lower belt line seal lips. A predetermined gap is formed between the lower belt line seal lip and the divider wall portion when the window glass is in an open state, and the lower belt line seal lip contacts the divider wall portion when the window glass is in a closed state.

First claim

What is claimed is:

1. A seal for an automobile door of an automobile, the automobile having a cabin, the automobile door having a body and a window frame that supports a peripheral portion of a window glass, the seal comprising:
a glass run configured to attach to the window frame such that the window glass is movable up and down within the window frame; and
a belt line inner seal configured to attach to an inner side of a belt line of the body of the automobile door, wherein the belt line inner seal is located closer to an inside of the cabin than an outside of the cabin of the automobile when the automobile door is closed, and extends in a lengthwise direction of the automobile when the automobile door is closed,
the glass run including a vertical portion extending in a moving direction of the window glass such that a distal lower end of the vertical portion forms an opening inside the body of the automobile door, and
the belt line inner seal is integrally molded with the vertical portion of the glass run, wherein:
the vertical portion of the glass run includes a vertical seal lip which is configured to be elastically deformed when contacting an inner surface of the window glass facing the inside of the cabin when the automobile door is closed,
the belt line inner seal includes an upper belt line seal lip and a lower belt line seal lip which are configured to be elastically deformed when contacting the inner surface of the window glass facing the inside of the cabin when the automobile door is closed, the upper and lower belt line seal lips extending in the lengthwise direction of the automobile when the automobile door is closed, and being vertically spaced from each other,
the vertical seal lip of the glass run is integral and unitary with an end of each of the upper and lower belt line seal lips in the lengthwise direction of the automobile, and
the vertical portion includes a divider wall portion extending in a vertical direction and protruding toward the outside of the cabin between the upper and lower belt line seal lips, and
a space surrounded by the seal and the window glass is at least partially divided by the divider wall portion into a space in the vertical portion and a space in the belt line inner seal.

2. The seal for the automobile door of claim 1 , wherein
the lower belt line seal lip is spaced apart from the divider wall portion to form a predetermined gap between the lower belt line seal lip and the divider wall portion when the window glass is in an opened state, in which the window glass is disengaged from the lower belt line seal lip, and
when the window glass is in a closed state, the window glass contacts the lower belt line seal lip to elastically deform the lower belt line seal lip causing the lower belt line seal lip to contact the divider wall portion.

3. The seal for the automobile door of claim 2 , wherein
the divider wall portion has an edge, and the edge has a notch configured to receive the lower belt line seal lip when the window glass in the closed state.

4. The seal for the automobile door of claim 1 , wherein
the divider wall portion is inclined such that an upper portion of the divider wall portion extends toward the outside of the cabin when the automobile door is closed to a greater extent than a lower portion of the divider portion extends toward the outside of the cabin when the automobile door is closed.

5. The seal for the automobile door of claim 1 , wherein
an upper portion and a lower portion of the divider wall portion are continuous with the vertical seal lip.

6. The seal for the automobile door of claim 1 , wherein
the vertical portion includes an inner wall portion and an outer wall portion the inner and outer wall portions being arranged to sandwich the window glass therebetween,
the vertical seal lip is formed on an outer surface of the inner wall portion,
the inner wall portion and the vertical seal lip are connected via a connecting wall portion extending from the inner wall portion to the vertical seal lip, and
the connecting wall portion extends from a proximal end to a distal end of the vertical seal lip.

7. The seal for the automobile door of claim 6 , wherein
the connecting wall portion has a first end and a second end, and
the connecting wall portion is inclined such that the first end of the connecting wall portion is positioned lower than the second end of the connecting wall portion.

8. The seal for the automobile door of claim 1 , wherein
the divider wall portion is curved and an upper portion of the divider wall portion extends toward the outside of the cabin when the automobile door is closed to a greater extent than a lower portion of the divider wall portion extends toward the outside of the cabin when the automobile door is closed.
