JPS6071325A - Sealing structure of car door glass - Google Patents

Abstract

PURPOSE:To prevent jolting of a door glass due to a negative pressure during running and to improve a sealing effect, by a method wherein the one end of the part, on the outer side of a car, of a cover member is bent in an L-shape to form a bent part. CONSTITUTION:A bracket 11, extended from a car body side, and a cover member 12, extended from a door sash, are secured by means of a fixing device 13. The forward end of a glass holder 16, having the one end secured to a door glass 15, is guided and extended such that it makes resilient contact with a glass run 14, and is held between the nip formed by seal lips 14a and 14b. The one end of the part, on the outer side of a car, of a cover member 12 is bent in an L-shape to form a bent part 12b, and the forward end of the bent part 12b is positioned so that it makes contact with the side of a holder 16. This, even if the door glass 15 is swung to the outer side of a car due to a negative pressure during running, causes the bent part 12b of the cover member 12 to act as a stopper which stops the movement of the holder 16, resulting in prevention of jolting of the door glass.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides 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 run attached to a cover member extending from the door sash and raised and lowered. Regarding.

Conventionally, an example of the structure of the door glass door near the triangular bunch l 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 to a fixture 4.
A glass holder 7 is provided extending beyond the door glass 6 so as to come into elastic contact with the glass run 5 which is fitted and fixed to the cover member 3. The seal rims 5a and 5b of the glass 7'15 abut on both sides of the glass boulder 7 to improve adhesion.

However, in 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 shake. This has disadvantages in that it causes noise or wind leakage, as well as sealing failure due to fluctuations in the seal line.

An object of the present invention is to obtain a structure that eliminates the various drawbacks of the conventional door glass seal structure as described above, and to provide a device that 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 extending from a door sash (not shown), and both are fixed using a fixture 13. 14 is a glass yy fitted and fixed by a cover member 12;
It includes seal lips 14a and 14b extending toward the inner pocket 1, and a seal lip 14C that extends largely toward the door glass 15, is bent in a substantially square shape, and has its tip abutted against the door glass 15. A retaining lip 14d is provided on the remaining portion (in the middle of the glass run 14), and the protruding portion 12B of the cover member 12 is
Attach to cover.

A glass holder 1 whose one end is fixed to the door glass 15
The tip of the glass run 14 is guided and extended so as to make elastic contact with the glass run 14, and forms a seal lip 14a.

It is surrounded by 14b.

Further, in the present invention, a bent portion 12b is provided at one end of the outer side portion of the cover member 120 and is folded into an abbreviated shape, and the tip of the bent portion 12b is configured to abut against the side surface of the glass holder 16.

Further, FIG. 4 shows a second embodiment of the present invention. The basic configuration in this figure is approximately the same as that in FIG. 3, and therefore is designated by the same reference numerals. That is, in addition to the configuration shown in FIG. 3, a sub-seal member 18 is provided between the bent portion 12b of the cover member 120 and the glass holder 16. This sub-seal member 18 eliminates the gap exposed to the outside of the vehicle, enhances the sealing effect, and provides an appearance with one surface being flattened.

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 outside the vehicle due to negative pressure during driving, the cover member 120 bends 1.
Since the door glass 2b acts as a stopper to stop the movement of the glass holder 16, rattling of the door glass 15 can be prevented.

Therefore, leakage caused by the above operation can be eliminated. Furthermore, the seal line does not change depending on the position of the door glass 15, and there is an effect that no cooling failure occurs. Glassura/14 seal lip 14
a, 14b abut against the glass holder 16, and the large seal lip 14C suppresses the door glass 15 from external forces, making the sealing effect even stronger. Furthermore, in the second embodiment of the present invention, by adding the sub-seal member 18 in addition to the above configuration, the sealing effect can be further enhanced, and the external surface can be made flat, which is effective in terms of appearance and wind pressure prevention. .

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.
