[Conventional technology]

It is well known in the prior art to provide a weatherstrip device of the above-mentioned type in order to ensure the sealing property in the vehicle interior.

FIG. 1 is a side view of an automobile, and FIG. 2 is an enlarged sectional view taken along line II-II of the automobile. Reference numeral 1 is a vehicle body of the automobile, and 2 is a door pivotally attached to the vehicle body 1. The door 2 is the door body 3
2 has a door frame 4 fixed to it, and a glass run 6 is fitted to a channel portion 5 formed on the window opening side of the door frame 4 as shown in FIG. When the supported window glass 7 moves up and down, the edge thereof slides on the glass run 6.

The reference numeral 8 in FIG. 2 denotes a roof panel that constitutes the upper part of the vehicle body 1, 9 is a roof side rail extending in the front-rear direction of the vehicle body, and this rail 9 is an inner panel 10 located inside the vehicle, It consists of an outer panel 11 located outside the vehicle, and both panels 10 and 11 are the upper mating flange 1
2 and the lower mating flange portion 13 are integrated by spot welding. Reference numeral 14 denotes a drip channel fixed to the roof side rail 9 and the roof panel 8, to which a drip molding 15 is fixed, and the molding 15 and the roof panel 8 form a rain gutter. .

A weather strip 16 made of a soft elastic material such as rubber or soft synthetic resin is provided around the door frame 4 for the purpose of maintaining the sealing property in the vehicle interior when the door 2 is closed. ing. Weather Strip 16
The base 17 is fitted and held in a weatherstrip mounting groove 18 formed in the door frame 4. The mounting groove 18 extends along the outer periphery of the door frame 4 along its entire length, and the weather strip 16 is mounted therein.

When the door 2 is closed as shown in FIGS. 1 and 2, the seal portion 19 of the weather strip 16 is elastically deformed and comes into pressure contact with the outer panel surface of the roof side rail 9. Further, as shown in FIG. 1, the weather strip portions attached to the front portion 4a and the rear portion 4b of the door frame 4 are the front pillars of the vehicle body 1.
20 and center pillar 21 are pressed against each other. Also, as shown in FIG. 2, the lip 22 of the weather strip 16 is pressed against the drip molding 15. In this way, it is possible to prevent wind and rainwater from entering the vehicle interior from around the door frame when the door is closed.

The above-mentioned weatherstrip 16 and the weatherstrip mounting groove 18 for holding the same constitute a conventional door weatherstrip device, but in order to further ensure the sealing property in the vehicle interior, in addition to this weatherstrip device, As shown in FIG. 2, a weather strip 116 made of a soft elastic material is provided on the inner side of the vehicle. In the example of FIG. 2, the opening trim 23 fitted to the lower mating flange portion 13 of the roof side rail 9 and the weather strip 116 are provided.
(Hereinafter referred to as an opening weather strip) is integrally formed, and when the door 2 is closed, the opening weather strip 116 is pressed and elastically deformed by the door frame 4, and a part of the opening weather strip 116 is formed on the outer panel surface of the roof side rail 9. It also press-contacts and enhances the sealing performance inside the vehicle.

[Problems to be solved by the device]

As described above, conventionally, in addition to the door weatherstrip device, the opening weatherstrip 116 is provided, but since these weatherstrips 16 and 116 are located adjacent to each other, they may interfere with each other. .
In particular, when the door 2 is closed with a strong force, the weather strip 16 is deformed as shown by the chain line in FIG. 2 and hits the opening weather strip 116 when closed. If the position and shape of each weather strip 16 and 116 are set so as to prevent such interference, the sealing function may be deteriorated.

While the above-mentioned interference operation is repeated, the opening weather strip 116 is permanently deformed so as to be depressed inward. Since the opening weather strip 116 is attached to a portion that can be seen from the outside when the door 2 is opened, if it is permanently deformed as described above, its appearance is deteriorated.

Further, when the opening weather strip 116 is integrated with the opening trim 23, there is an advantage that the mounting work can be simplified as compared with the case where these members are separated from each other, but when the opening trim 23 is mounted, this may wavy. The opening weather strip 116 is also attached in a wavy state in such a case, and the appearance thereof is significantly deteriorated.

An object of the present invention is to provide an automobile door weather strip device in which the above-mentioned conventional drawbacks are eliminated by a simple structure.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a door weatherstrip device of the type described at the beginning, in which when the door is closed, the weatherstrip is attached to a lower mating flange portion of an outer panel of a roof side rail and a lower inner flange portion of an inner panel. The weather strip is protruded to the inside of the vehicle so as to be pressed into contact with the attached interior material, and the weather strip is fitted and held to the door frame portion facing the lower mating flange portion with the door closed. We propose a structure with a weatherstrip mounting groove.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 3 is a sectional view similar to FIG. 2, showing an example of a door weather strip device according to the present invention, but the basic structure of the vehicle body structure to which the door weather strip device shown here is mounted is It is the same as that described above with reference to FIGS. 1 and 2, and the appearance of the vehicle body is not different from that shown in FIG. Therefore, among the elements in FIG. 3,
1 and 2 are included in the same or similar parts as in the conventional configuration.
The same reference numerals as those shown in the drawings are given, and the description thereof will be omitted. In the following description, FIG. 1 will be referred to as necessary.

The door weather strip device shown in FIG. 3 is also formed in the door frame 4 in the same manner as in the conventional case, and a weather strip mounting groove 18 extending along the outer periphery of the frame 4 and a base 17 thereof are fitted and held therein. Although it has a weather strip 16, it is different from the conventional one.
The second base portion 117 of the weather strip 16 is fitted and held on the door frame portion facing the lower mating flange portion 13 of the roof side rail 9 with the door 2 largely protruding toward the inside of the vehicle. Weather strip mounting groove 118
Is formed. That is, the conventionally used opening weatherstrip is omitted, and instead, the weatherstrip 16 is projected to the region occupied by the conventional opening weatherstrip, and this protruding portion extends over the entire length of the door frame 4. By retaining the second mounting groove 118, the weather strip 16 also functions as a conventional opening weather strip.

Also, in the example of FIG. 3, the opening trim 23 shown in FIG. 2 is also omitted, and instead, an inner garnish 24 that has been conventionally used as an interior material in the vehicle is extended to the outside of the vehicle. It covers the lower mating flange 13 of. Other configurations are the same as those in FIG. The dashed line in FIG. 3 indicates the weather strip 16
The shape of the weather strip 16 when an external force is not applied to is shown.

When the door 2 is closed as shown in FIGS. 1 and 3, the weather strip 16 is pressed against the outer panel surface of the roof side rail 9 while its seal portion 19 is elastically deformed as shown in FIG. At the same time, a weather strip protruding inside the car
The 16 sealing portions 19 also press-contact with the inner garnish 24 attached to the lower mating flange portion 13 of the roof side rail 9 to seal the interior of the vehicle. That is, only one weatherstrip 16 functions as both a conventional weatherstrip and an opening weatherstrip.

Since the opening weather strip can be omitted as described above, there is no room for causing a problem that the appearance thereof is deteriorated due to permanent deformation or waviness of the opening weather strip. Further, since it is not necessary to consider any interference between the weatherstrip 16 and the opening weatherstrip, the degree of freedom in designing the shape of the weatherstrip 16 is increased.

Further, since the opening weather strip 116 can be omitted, the opening trim 23 can be omitted as in the embodiment shown in FIG. 3, and the lower mating flange portion 13 can be covered with the inner garnish 24 to enhance its appearance. Installation work of the trim 23 is unnecessary. Since the opening trim 23 is generally struck and attached to the lower mating flange portion 13 by a tool such as an air hammer, the work thereof is very complicated, but such work can be omitted. Further, by covering the lower mating flange portion 13 with the inner garnish 24 extending into the vehicle interior, a sense of unity in design can be provided, and the appearance thereof is further improved.

Of course, instead of the inner garnish 24, the lower fitting flange portion 13 may be covered with an opening trim as in the conventional case. In this case, when the door 2 is closed, the seal portion 19 of the weather strip 16 is pressed against the opening trim. . Also opening trim and inner garnish
It is also possible to expose the lower mating flange portion 13 without covering it with an interior material such as 24. In this case, when the door 2 is closed, the sealing portion 19 of the weather strip 16 is covered by the roof side rail. 9 lower flange 13
Press directly against.

Although the door 2A is also arranged at the rear of the door 2 in the vehicle shown in FIG. 1, the present invention is naturally applicable to the weather strip device for the door 2A.

[Effect of device]

According to the present invention, since the conventional opening weatherstrip can be omitted, it is possible to prevent deterioration of the appearance due to permanent deformation and waviness of the opening weatherstrip, and it is possible to omit the mounting work and improve workability.
