JPS6071324A - Sealing structure of car door glass - Google Patents

Abstract

PURPOSE:To prevent jolting of door glass due to a negative pressure during running, by providing an extension part formed by extending the one end of the part, on the outer side of a car, of a cover member to the outer surface of a glass holder. CONSTITUTION:A glass run 14 is fixedly engaged with a cover member 12 extended from a door sash. The glass run 14 has inwardly-extending seal lips 14a and 14b and a seal lip 14c, and further has a retainer lip 14d which is located at about the middle part thereof and serves to engage with a projection 12a on a cover member 12 in a manner that it covers the projection. One end of the part, on the outer side of a car, of the cover member 12 is extended to the outer side of a glass holder 16 to form an extension part 12b, and the extension part 12b is forced into slidable contact with the outer surface of a holder 16. This, even if a door glass 15 is swung outward due to a negative pressure during running, causes the extension part 12b to act as a stopper which stops the movement of the holder 16.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing structure for a door glass in which one end of a glass holder fixed to the door glass is brought into elastic contact with a glass thin fixed to a cover member extending from the door sash and raised and lowered. .

Conventionally, an example of the door glass seal structure near the triangular badge 1 at the front end of the front door of an automobile shown in FIG.
As shown in the figure. That is, a bracket 2 extending from the vehicle body side and a cover member 3 extending from a door sash (not shown) are connected by a fixture 4.
A glass holder 7 is provided extending from the door glass 6 so as to come into elastic contact with the glass holder 15 which is fitted and fixed to the cover member 3. The seal lips 5a and 5b of the glass run 5 abut on both sides of the glass holder 7 to improve adhesion.

However, with the conventional door glass seal structure as described above, if there is rattling due to poor installation of the door glass 6, negative pressure during driving will be applied to the door glass 6, causing the door glass to swing. This has disadvantages in that it causes noise or wind leakage, and sealing defects occur due to fluctuations in the seal line.

It is an object of the present invention to provide a device which has a structure that eliminates the various drawbacks of the conventional door glass seal structure as described above, and which eliminates rattling and sealing defects.

The present invention will be described in detail below with reference to the drawings.

That is, in FIG. 3, 11 is a bracket extending from the vehicle body side, 12 is a cover member (not shown) extending from a door sash, and both are fixed using a fixture 13. Numeral 14 is a glass run that is fitted and fixed by the cover member 12, and has seal lips 14a and 14b that extend inward, and extends largely toward the door glass 15 side, and is bent in a substantially dogleg shape so that the tip thereof is attached to the door glass 15. 14C.

Further, a retaining lip 14d is provided approximately in the middle of the glass run 14, and is engaged so as to cover the protrusion 12& of the cover part 12.

The tip of the glass holder 16, which has one end 1634 attached to the door glass 15, is guided and extended so as to come into elastic contact with the glass run 14, and is held between the seal lips 14EL and 14b.

Furthermore, in the present invention, an extending portion 12b is provided that extends one end of the outer side portion of the cover portion 1412 to the outer surface of the glass holder 16, and the extending portion 12b extends from the outer surface of the glass holder 16. It is formed so that it can slide freely. Reference numeral 17 is a hair-planting member that is attached depending on the concubine.

The present invention relates to a seal structure for an automobile door glass as described above, and has the following operational effects. That is, even if the door glass 15 swings toward the outside of the vehicle due to negative pressure during driving, the extended portion 12b of the cover member 12 acts as a stopper to stop the movement of the glass holder 16, thereby preventing the door glass 15 from rattling. can be prevented.

Therefore, noise or wind leakage caused by the above operation can be eliminated. Fourth, the seal line does not vary depending on the position of the door glass 15, and there is an effect that seal failure does not occur. Seal lip 14 of glass run 14
a, 141) clamps the glass holder 16, and the large seal lip 14c presses the door glass 15 outward, so the sealing effect is strong.

As described above, the present invention provides a door glass seal structure near the triangular patch at the front end of a front door of an automobile, and has the advantage of providing a structure with better sealing properties and no rattling.
