Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal part structure provided on a vehicle door, particularly a front side door.

[0002]

2. Description of the Related Art Many sealing parts are attached to automobile doors, especially front side doors.

A typical example of the arrangement of such seal components will be described with reference to FIG. 4. Reference numeral 1 denotes an inside seal attached to the door waist W of the front side door F, which is in close contact with the door window panel P. is there.

A corner piece 2 is arranged in front of the inside seal 1, and a lower sash 3 for guiding the front edge of the door window panel P is arranged under the rear side of the corner piece 2.

The door weather strip 4 is attached from the lower portion of the front side portion of the corner piece 2 to the front side portion, the lower side portion and the rear side portion of the front side door F,
At the rear end of the door weather strip 4, a rear molding part 5 is provided behind the inside seal 1 (a structure of this type is, for example, the one disclosed in Japanese Utility Model Laid-Open No. 63-176817). ..

[0006]

SUMMARY OF THE INVENTION
It is provided in order to ensure watertightness and airtightness at each location. For example, as shown in FIG. 4, in the door waist portion W, the inside seal 1 and the corner piece 2 or the rear portion due to a dimensional error or the like. There is a problem that a gap C is likely to be formed between the mold forming portion 5 and such a gap C impairs watertightness and airtightness.

Therefore, the present invention provides a vehicle door seal component structure capable of improving watertightness and airtightness and reducing the number of components.

[0008]

[Means for Solving the Problems] An inside seal attached to a door waist portion of a front side door, and a corner piece arranged in front of the inside seal,
The rear mold forming portion of the door weather strip arranged behind the inside seal is integrally formed.

[0009]

By integrally molding the inside seal, the corner piece, and the rear mold forming part, there is no room for forming a gap at the front and rear ends of the inside seal, and the watertightness and airtightness are improved and the number of parts is reduced.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. It should be noted that each of the drawings is a diagram schematically shown as in the conventional case, and the same mode parts as those of the conventional structure are designated by the same reference numerals for description.

In the embodiment shown in FIG. 1, an inside seal 1 attached to a door waist portion W of a sashless type front side door F, a corner piece 2 arranged in front of the inside seal 1, and an inside seal 1 The rear mold forming part 5 of the door weather strip 4 arranged at the rear of is integrally molded by a mold.

A lower sash 3 for guiding the front edge of the door window panel P is attached to the lower portion of the rear side of the corner piece 2. The lower sash 3 is extruded in advance, and is integrally fixed to the corner piece 2 at the same time when the inside seal 1, the corner piece 2 and the rear mold forming portion 5 are formed, or is inserted and fixed after the molding. It is something.

A door weather strip 4 is attached to the lower portion of the front side portion of the corner piece 2 to reach the front side portion, the lower side portion and the rear side portion of the front side door F.

The door weather strip 4 is also extruded in the same manner as the lower sash 3, and when the inside seal 1, the corner piece 2 and the rear molding portion 5 are molded, the front end portion is the corner piece 2. On the other hand, the rear end portions are integrally fixed to the rear die molding portion 5 at the same time, or are inserted and fixed after the die molding.

Although the door weather strip 4 is not provided with a component having the same function as the rear mold portion 5 on the front end side, it is provided as a separate component because it is integrated with the corner piece 2. It has not been done.

According to the structure of the above embodiment, since the inside seal 1, the corner piece 2, and the rear mold forming part 5 are integrally formed, there is no room for forming a gap at the front and rear ends of the inside seal 1, and therefore the watertightness is ensured. , The airtightness can be increased.

Further, since the inside seal 1, the corner piece 2 and the rear molding portion 5 are integrally molded, it is advantageous in that the number of parts is reduced.

Next, a second embodiment will be described with reference to FIG. In this embodiment, the corner piece 2 and the rear mold forming part 5 are
When each of (1) and (2) is molded, the inside seal 1 preliminarily extruded is set to integrally mold the three members, and the lower sash 3 and the door weather strip 4 are attached as in the first embodiment.

Therefore, in this embodiment as well, there is no room for forming a gap at the front and rear ends of the inside seal 1.
Watertightness and airtightness can be improved. Further, in this embodiment, since the inside seal 1 is manufactured by inexpensive extrusion molding, there is an advantage that the die cost and the like can be reduced.

Next, a third embodiment will be described with reference to FIG. In this embodiment, the inside seal 1, the corner piece 2, the rear mold forming portion 5, and the lower sash 3 are integrally formed by molding. Then, when molding the inside seal 1, the corner piece 2, the rear mold forming portion 5, and the lower sash 3, the front end portion of the door weather strip 4 extruded in advance is formed with respect to the corner piece 2 and the rear end portion. It is formed by integrally fixing to the rear mold forming portion 5 at the same time, or by inserting and fixing after molding.

Therefore, also in this embodiment, since there is no room for a gap to be formed at the front and rear ends of the inside seal 1, the watertightness and airtightness can be improved, and the parts other than the door weather strip 4 are integrally molded. Therefore, the number of parts can be significantly reduced.

[0022]

As described above, according to the present invention, since the inside seal, the corner piece and the rear mold forming portion of the door weather strip are integrally formed, adjacent corner pieces at the front and rear ends of the inside seal or the above There is no gap between the rear molding part and the watertightness and airtightness.

By integrating the above three parts, the number of parts as a whole can be reduced.
