[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a door weather strip having an outer seal, a main seal, and an inner seal for sealing between a body of a vehicle with a door sash and a door.

[0002]

[Prior Art]

 Description will be made with reference to FIGS. 1 to 5. Conventionally, a door weather strip 13 and an inner seal 14 which is a separate body from the door weather strip 13 have been used as means for sealing between a body opening edge 1 of a vehicle with a door sash, a front door 2a and a door 2 including a rear door 2b. A combination of and is used. In detail, the door weather strip 13 is formed by combining a base portion 13a attached to the door sash 5 via a retainer 5a with a lip-shaped outer seal 13b and a hollow main seal 13c that elastically contact with the body opening edge 1 respectively. The inner seal 14 includes a trim 14a fitted in a flange 1a provided on the vehicle inner side 8 of the body opening edge 1 and a hollow seal portion 14b elastically contacting the vehicle inner convex portion 5b of the door sash 5. is there.

However, in the above-mentioned conventional seal structure, as shown in FIGS. 4 and 5, there are 16 molding portions Q provided in the middle of the extrusion molding portion P of the weather strip per unit, which is a cause of high cost. That is, when the door 2 is closed, the glass run 5c, the sash convex portion 5b, the seal portion 14b, and the trim 14a are different from each other. As shown in FIG. 3, the center pillar portion has problems such as poor appearance and interference between the main seal 13c of the rear door 2b and the seal portion 14b of the inner seal 14 when the door is opened and closed.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that there are many molding points, the cost is high, the appearance is not good, and the seal members interfere with each other in the rear door 2b when the door 2 is opened and closed.

[0005]

[Means for Solving the Problems]

 The present invention is a door weather strip that seals between a door opening edge 1 and a door 2 of a vehicle with a door sash at three points. The body opening is attached to a base portion 3a attached to the door sash 5 via a retainer 5a. The lip-shaped outer seal 3b and the hollow main seal 3c, which are elastically contacted with the rim 1, respectively, are integrally joined, and further, the hollow main seal 3c is fitted to the vehicle inner side 8 to the vehicle inner convex portion 5b of the door sash 5. Together with the grip 3d, a hollow inner seal 3e that elastically contacts the trim 4 attached to the inside of the body opening edge 1 is integrally joined.

[0006]

【Example】

 An embodiment will be described with reference to FIG. 1 and FIGS. 6 to 8. 1 is a body opening edge of an automobile with a door sash, 2 is a front door 2a and a rear door 2b, 3 is a door weather strip, and a retainer 5a is provided. A lip-shaped outer seal 3b and a hollow main seal 3c elastically contacting the body opening edge 1 are respectively coupled to a base 3a attached to the door sash 5 via the door sash 5, and the hollow inner main seal 3c is further provided with a door sash 5 inside the vehicle. A hollow inner seal 3e that elastically contacts the trim 4 attached to the body opening edge vehicle inner side flange 1a is integrally coupled with a grip 3d fitted to the vehicle inner side convex portion 5b. A grip claw T is provided on the inner surfaces of the trim 4 and the grip 3d so as to project therefrom.

Explaining the operation, as shown in FIGS. 7 and 8, the number of die forming portions Q provided in the middle of the extrusion forming portion P of the weatherstrip is reduced to 12 places per unit, and the cost is reduced. When the door 2 is closed, the connection between the grass run 5c, the door weather strip 3 and the trim 4 is reduced, and the convex portion 5b of the sash is covered with a part of the door weather strip 3 to improve the appearance, and the center pillar. Since the rear seal main seal 3c and the inner seal 3e are integral with each other, they do not interfere with each other when the door is opened and closed, and the inner seal 3e is firmly held by the sash convex portion 5b by the grip 3d so that it shifts backward. Is also prevented.

[0008]

[Effect of the device]

 Since the present invention is configured as described above, the number of molding portions is reduced, the cost is reduced, and the sash convex portion 5b is covered with a part of the door weather strip 3 when the door 2 is closed, and the appearance is improved. Also, when the door is opened and closed, the interfering portion is eliminated, and the inner seal 3e is firmly held by the sash convex portion 5b, so that it does not slip backward.
