[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door sash structure for an automobile, and more particularly to a door sash having an improved corner portion.

[0002]

2. Description of the Related Art As a conventional door sash structure of this kind, there is, for example, one shown in FIGS.
An automobile door 1 includes a door body 2 below a door waist line and a door sash 3 above the door body 2.
Are formed by the door outer 4 and the door inner 5. The door sash 3 has a retainer 6 attached to a mounting surface 5a of the door inner 5, and a weather strip 8 for sealing between the retainer 6 and a peripheral edge 7 of a door opening of the vehicle body. This weather strip 8
Are integrally formed from a fixed portion 8a fitted to the retainer 6 and a hollow portion 8b for sealing between the fixed portion 8a and the peripheral edge portion 7 of the door opening.

When the automobile door 1 is closed, in the general portion of the door sash 3, the hollow portion 8b has
, And is deformed and sealed as shown by a solid line from a two-dot chain line in FIG.

[0004] As another example of this type, there is one described in Japanese Utility Model Application Laid-Open No. 63-16231.

[0005]

However, in such a conventional device, the general portion of the hollow portion 8b in FIG. 5 is located at a position shown by a two-dot chain line in FIG. 5, the hollow portion 8b is lower than the general portion, as shown by the dashed line in FIG.
Therefore, in this state, when the hollow portion 8b in the corner portion 9 contacts the door opening peripheral edge portion 7, the hollow portion 8b is deformed as shown by a solid line in FIG. And sufficient sealing performance cannot be secured,
It may cause wind leakage. Further, since such normal bending does not occur, a large reaction force is generated when the hollow portion 8b is deformed, and a large force is required when the door is closed.

As a countermeasure, there is a method of inserting a spacer (not shown) into the hollow portion 8b to maintain the shape. However, this causes an increase in the number of parts and an increase in cost, and the hollow portion 8b is closed even when the door is closed. It is difficult to deform and has an adverse effect.

Accordingly, an object of the present invention is to provide an automobile door sash structure which can easily close the automobile door while ensuring the sealing property and does not increase the number of parts.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and a retainer fixed inside a door sash is provided on a retainer fixed inside a door sash to seal a space between the door opening and the periphery of a vehicle body. While the strip is attached, a sash garnish that covers the interior side of the door sash is mounted inside the door sash, and the weather strip is fixed to the retainer,
In the automobile door sash structure having a hollow portion that abuts against the peripheral edge of the door opening when the door is closed and elastically deforms, a retainer of the door sash has a mounting portion to which an upper terminal portion of the sash garnish is mounted. ,
A push-up portion for pushing up the hollow portion upward is formed at an upper portion of the sash garnish.

[0009]

According to this means, the hollow portion of the door sash tends to hang downward at the corner of the door sash.
The push-up portion of the sash garnish goes under the hollow portion, and the hollow portion is pushed upward. Therefore, the hollow portion is brought into contact with the peripheral edge of the door opening at a regular position and is elastically deformed, so that a reliable seal is achieved.

As described above, since the hollow portion is elastically deformed at the regular position, the door can be easily closed without generating a large reaction force when the door is closed unlike the related art.

Further, since a reaction force from the hollow portion acts on the push-up portion of the sash garnish, the sash garnish is prevented from rattling.

Moreover, the number of components is not increased by using the existing sash garnish and retainer.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.

FIGS. 1 and 2 show an embodiment of the door sash structure of the present invention.

First, the structure will be described.
2, a door body 13 below the door waist line and a door sash 14 above the door body 13 are formed by a door outer 15 and a door inner 16. The door sash 14 has a retainer 17 mounted on the mounting surface 16a along the substantially horizontal direction of the door inner 16 over substantially the entire periphery thereof. The strip 1
9 is attached.

The weather strip 19 is provided on the retainer 1.
7 and a hollow portion 19b abutting on the peripheral edge portion 18 of the door opening. The hollow portion 19b comes into contact with the door opening peripheral portion 18 with a predetermined force and is elastically deformed.

Further, the door inner 1 of the door sash 14
The sash garnish 20 is attached to the interior of the vehicle 6.

More specifically, the retainer 17 is formed with a fitting recess 17a as a mounting portion into which the upper terminal portion 20a of the sash garnish 20 is fitted. At the upper part of the sash garnish 20, there is formed a push-up portion 20b which goes under the hollow portion 19b and pushes up the hollow portion 19b.

Next, the operation of the weather strip mounting structure having the above configuration will be described.

When the vehicle door 12 is closed, the hollow portion 19b abuts against the peripheral edge portion 18 of the door opening and is elastically deformed to seal.

In the corner portion 21 of the door sash 14, particularly when the door 12 is open, the hollow portion 19b tends to hang down as shown by the dashed line in FIG. But this hollow part 1
9b, the hollow portion 19b
It is pushed up as shown by the solid line. Therefore, when the vehicle door 12 is closed from this state,
The hollow portion 19b is located at the regular position,
By being elastically deformed by contacting the seal 8, a reliable seal is obtained (see FIG. 1). In addition, since the hollow portion 19b abuts on the peripheral edge portion 18 of the door opening and is elastically deformed at its proper position, a large reaction force is not generated unlike the related art, and the closing of the door 12 for the automobile can be easily performed. Will be performed.

A reaction force from the hollow portion 19b of the weather strip 19 acts on the push-up portion 20b of the sash garnish 20, and the upper end portion 20a of the sash garnish 20 is fitted into the fitting recess 17a of the retainer 17. , The rattling of the sash garnish 20 is prevented.

Further, the existing sash garnish 20
The use of the retainer 17 does not increase the number of parts.

[0024]

As described above, according to the present invention, in the corner portion of the door sash, the hollow portion is pushed upward by the push-up portion of the sash garnish. In this position, it can be securely sealed by abutting against the edge of the door opening and elastically deforming, and it is easy to close the car door without generating a large reaction force when the door is closed. Can be. Further, since the reaction force from the hollow portion of the weather strip acts on the push-up portion of the sash garnish, it is possible to prevent the sash garnish from rattling. Moreover, by utilizing the existing sash garnish and retainer, there is a practically useful effect that the number of parts is not increased.
