Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is a door glass that is mounted along the inner periphery of a door frame of an automobile and seals around the door glass when the door glass rises and is closed. It concerns weather strips.

[Prior Art] As a door glass weather strip (hereinafter, simply referred to as a weather strip), as shown in FIG. 3, a mounting base 30 having a U-shaped cross section and mounted on the door frame 1 and an outer side of the base 30. One end is connected to the tip of the side wall 31 and the other end is connected to the tip of the support wall 33 extending downward from the bottom of the base 30, and the seal wall 34 pushed up by the door glass 2 when the door glass is closed and the base 30. There is used a weather strip 3 having an inner seal lip 35 extending obliquely upward from the lower end of the side wall 32 on the inside of the vehicle and having a tip end in contact with the inner surface of the door glass 2 (Actual No. 1-123917). Then, in this weather strip 3, as shown in FIG. 4, the upper end of the door glass 2 is wrapped with the seal wall 33, and the inner seal lip is formed.
When 35 contacts the inner surface of the door glass 2, excellent sealing performance is exhibited.

By the way, in this weather strip, the tip of the inner seal lip 35 that comes into contact with the door glass 2 has a side wall 31 outside the vehicle.
When the door glass is opened, or when seen through the transparent door glass 2 from the outside, it is located at a position lower than the tip of the above, and a gap is formed between the both tips, which is not preferable in appearance. Therefore, the inner seal lip 35 is extended as shown by the broken line in FIG. 3, and the length is such that the tip reaches the sealing wall 34 when the door glass 2 is lifted and closed as shown by the broken line in FIG. Then, the tip of the inner seal lip 35 is hidden and the gap is not visible.

However, in this way, the inner seal lip
The tip of 35 enters the back side of the support wall 33 as shown by the broken line in FIG. 4, and when the door glass 2 is lowered, the inner seal lip 35 remains attached to the inner end corner of the seal wall 34. There is a risk that it will not return to its original shape.

[Problems to be solved by the present invention] Therefore, in the present invention, even if the inner seal lip 35 is formed to be long enough to reach the seal wall 34 when the door glass is closed, it may be attached to the seal wall 34 as in the conventional case. It is an object to provide a weather strip that does not have any.

[Means for Solving the Problems] As shown in FIGS. 1 and 2, the present invention provides a side wall 32 on the vehicle interior side of a mounting base 30 of a weather strip 3 with a seal wall 34 and a support wall at the upper end. An inclined surface 322 which is almost in contact with the connection portion with 33 and continues gently from the upper end in the extending direction of the seal wall 34.
In addition, the inner seal lip 35 is formed to have a sufficient length to reach the seal wall 34 when the door glass is closed.

[Operation and Effect] When the door glass 2 is lifted and closed as shown in FIG. 2, the inner seal lip 35 is lifted along with the door glass 2 and its tip comes into contact with the seal wall 34. By the way, since the user strip continuously forms the inclined surface 322 from the seal wall 34 to the side wall 32 on the vehicle inner side, even if the tip of the inner seal lip 35 is strongly pressed, the inclined surface is formed.
Even if it moves along the side wall 322 toward the side wall 32, it is not caught, and when the door glass 2 descends, the inner seal lip 35 returns to its original shape.

[Embodiment] FIGS. 1 and 2 show an embodiment of the present invention. As shown in FIG. 1, a weather strip 3 is attached to the inner periphery of the door frame 1.

The weather strip 3 includes a mounting base 30 that is assembled to the door frame 1, a seal wall 34 that is pushed up by the door glass 2 when the door glass is closed, a support wall 33 that supports the seal wall 34, and a door glass when the door glass is closed. The inner seal lip 35 is provided so as to abut the inner surface of the second member 2.

The support wall 33 extends downward from the bottom surface of the mounting base 30 in front of the side wall 32 on the vehicle inner side, and one end of the seal wall 34 is connected to the tip of the side wall 31 on the vehicle outer side of the mounting base 30 and the other end. Is connected to the tip of the support wall 33 to form a surface that faces the door glass 2 substantially vertically. The inner seal lip 35 extends obliquely upward from the lower end of the side wall 32 on the vehicle interior side of the mounting base 30. The length of the inner seal lip 35 is such that when the door glass 2 is closed and reaches the uppermost position, the tip end contacts the seal wall 34. Further, the tip end surface is shaped so as to closely contact with the seal wall 34.

A protrusion 321 is formed on a side wall 32 on the vehicle interior side of the mounting base 30 on the vehicle exterior side facing the door glass 2, and the projecting end is in contact with a corner portion connecting the seal wall 34 and the support wall 33. ing.
As a result, the opening of the gap S between the support wall 33 and the side wall 32 is closed. Then, on the side wall 32, the sealing wall pushed up by the door glass 2 with the protruding end as the upper end is pushed up.
An inclined surface 322 is formed in the direction of extending 34 (FIG. 2).

FIG. 2 shows a state of the weather strip 3 constructed as above when the door glass is closed. When the door glass 2 rises, the side surface of the inner seal lip 35 will be the door glass 2.
Is pressed against the inner surface of. Then, when the door glass 2 further rises and reaches the rising end, the inner seal lip 35 is lifted by the door glass 2, and the leading end thereof is curved inward and abuts on the inner end of the seal wall 34.

The rising end position of the door glass 2 inevitably has some variation. When the upward variation occurs, the inner seal lip 35 is rolled into the vehicle interior, and its tip is displaced from the inner end of the seal wall 34 toward the side wall 32. However, since the inner end and the side wall 32 form a continuous surface, the tip of the inner seal lip 35 does not catch on the corner of the inner end. Then, when the door glass 2 is lowered and opened, even if the inner seal lip 35 is in a rolled-in state, the tip of the inner seal lip 35 moves along the gentle continuous surface toward the seal wall 34 side and leaves the continuous surface to the original shape. Restore.

As described above, in the weather strip of the present invention, the inner seal lip can be made sufficiently long to prevent its tip from appearing in appearance when the door glass is closed, and when the door glass is opened, the inner seal lip is smoothly formed into its original shape. Can be returned.
