DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a seal structure of an automobile having a sashless door.

[Conventional technology]

A sashless door 3 having a door glass 2 ascending and descending, that is, a door without a window frame is supported on a vehicle body 1 of a hard-dop vehicle as exemplified in FIG. Is provided with a weatherstrip extending long along the opening.

FIG. 4 shows a quarter pillar 4 as an example of a vehicle pillar extending substantially vertically, and a retainer 5 is integrally fixed to the outer surface of such a pillar 4 along the pillar, and 5 holds a weather strip 6. The weather strip 6 is made of an elastic material such as rubber or soft synthetic resin. As described above, the weather strip 6 is attached to the outer surface of the vehicle body pillar along the longitudinal direction of the pillar.

The weather strip 6 is fitted to the retainer 5, that is, a base 7 fixed to the quarter pillar 4, and is integrally formed with the base 7, and a door glass edge 8 of the sashless door 3 is pressed against the base 7. And a seal portion 9. A hollow extending in the longitudinal direction of the weather strip 6 is formed in the sealing portion 9 such that when the door glass edge 8 is pressed against the sealing portion 9, the sealing portion 9 is easily elastically deformed in a direction of recessing into the interior I of the vehicle. A part 10 is formed.

FIG. 4 shows a state in which the sashless door 3 is closed by raising the door glass 2, and FIG. 5 shows a state in which the sashless door is opened or the door glass is lowered by closing the door glass. 4, the rear edge portion 8 of the door glass is pressed against the sealing portion 9 of the weather strip 6 in this state, and at this time, the hollow portion 10 is formed in the sealing portion 9, so that the sealing portion 9 is As shown, it is elastically deformed and elastically adheres to the door glass edge 8. Thus, the sealing performance of the vehicle interior I is maintained. Lower the door glass 2,
Alternatively, when the sashless door 3 is opened, the edge portion 8 of the door glass does not hit the seal portion 9 as shown in FIG. 5, so that the seal portion 9 returns to the natural state shown in FIG. 5 due to its elasticity.

In the examples of FIGS. 4 and 5, the hollow portion 10 is a partition 11
Are divided into two, but it is not necessary to separate them in this way, and in some cases, they may be separated into three or more.

The above-mentioned seal portion 9 further has a lip 12 projecting from the door glass edge 8 in a direction away from the rear side of the vehicle body 1. The lip 12 is covered by a finisher plate 13 fixed to the vehicle body 1. ing. By providing the lip 12 on the weather strip 6 and covering the lip 12 with the finisher plate 13 in this manner, it is possible to prevent a gap from being formed between the weather strip 6 and the finisher plate 13 and enhance the appearance thereof. is there.

Note that the finisher plate is a general term for a decorative member that covers a vehicle body or a component attached thereto, and generally includes a garnish or a molding. The finisher plate 13 shown in FIGS. 3 to 5 is a kind of garnish.

The quarter pillar 4 is shown in FIGS. 4 and 5 as an example of the body pillar, but the front pillar 14 shown in FIG.
Weather strips are similarly attached to body pillars such as these. In the case of the front pillar 14, a lip of the weather strip attached to the front pillar 14 projects from the front edge of the door glass of the sashless door 3 on the front side toward the front side of the vehicle body 1, and the lip forms a finisher plate ( (Not shown). in this way,
The lip projects from the edge of the door glass in a direction away from the front and rear of the vehicle body.

[Problems to be solved by the invention]

As described above, the sealing structure having the weather strip 6 can enhance the sealing property in the vehicle compartment I. In addition, the lip 12 of the weather strip 6 and the finisher plate 13 that covers the lip 12 enhance the appearance of the vehicle body. Is possible.

However, since the lip 12 constituting a part of the weather strip 6 is made of an elastic material such as rubber which is easily deformed,
With the door glass 2 raised, the sashless door 3
When the sealing member 9 is closed with a strong force, the sealing portion 9 of the weather strip 6 receives a strong external force from the edge portion 8 of the door glass, and when the sealing portion 9 is deformed as shown in FIG. A large pulling force acts on the rear wall portion 16, which also causes the lip 12 to move at the same time, which may jump out of the finisher plate 13 as shown by the chain line in FIG. In this case, since the lip 12 is exposed to the outside, its appearance is significantly reduced, and its appearance is impaired.

In order to eliminate the above-mentioned drawbacks, it is conceivable to increase the amount of protrusion of the lip 12 and make it difficult for the lip 12 to come out of the finisher plate 13. However, this increases the material cost of the weatherstrip 6 and increases its cost. .

Also, the deformation of the rear wall portion 16 is suppressed by increasing the thickness of the rear wall portion 16, or the projection 17 or 17
Proposals have been made to prevent the lip 12 from jumping out by providing a. However, it is difficult to enhance the effect of preventing the lip 12 from jumping out even though the material cost of the weatherstrip 6 is increased by these configurations.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automobile sealing structure in which the above-mentioned conventional disadvantages are eliminated by a simple structure.

[Means for solving the problem]

In order to achieve the above object, the present invention has a weather strip made of an elastic material attached to the outer surface of the vehicle body pillar along the longitudinal direction of the pillar, and the weather strip is fixed to the vehicle body pillar. A sashless door which is integrally formed with the base and is supported on the vehicle body so as to be openable and closable. When the edge is pressed, a hollow portion extending in the longitudinal direction of the weather strip is formed such that the seal portion is elastically deformed in a direction of recessing into the vehicle interior, and the seal portion is formed from the door glass edge portion. A lip protruding in a direction away from the vehicle body in a front-rear direction is provided. The lip is covered by a finisher plate fixed to the vehicle body. In the state where the lath is pressed against the seal portion, a middle rib constituting a part of the weather strip is provided in a hollow portion between the edge portion of the door glass and the root portion of the lip, and the hollow portion is formed by the middle rib. The present invention proposes an automobile seal structure characterized by being divided.

〔Example〕

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

1 and 2 are cross-sectional views similar to FIGS. 4 and 5, showing an example of a seal structure according to the present invention. The basic structure and operation of the seal structure shown here, and the appearance of an automobile employing this seal structure are the same as those described above with reference to FIGS. Therefore the third
The same or similar portions as those in FIGS. 5 to 5 are denoted by the same reference numerals, and only differences from the conventional art will be clarified below.

As shown in FIG. 1, when the sashless door 3 is closed by raising the door glass 2, the door glass edge 8 is pressed against the sealing portion 9 of the weather strip 6. 8 and lip 12 of weather strip 6
An intermediate rib 19 is provided in a portion of the hollow portion 10 between the base portion 18 and the hollow portion 10, and the hollow portion 10 is divided by the rib 19 in the front-rear direction of the vehicle body. The rib 19 is the weather strip 6
Therefore, the middle rib 19 is also made of an elastic material such as rubber or soft synthetic resin. Here, the hollow portion on the vehicle body front side divided by the middle rib 19 is referred to as a first hollow portion 10a, and the rear hollow portion is referred to as a second hollow portion 10b, and the operation thereof will be described in detail below.

The sashless door 3 is opened, so that as shown in FIG.
In this case, the form of the seal portion 9 at this time is the same as that of the conventional weather strip 6 shown in FIG.

Here, when the door 3 is closed with the door glass 2 raised, the door glass edge 8 is turned into a middle rib as shown in FIG.
The sealing portion 9 is pressed against the portion of the sealing portion 9 on the front side of 19, that is, the wall portion 20 of the sealing portion that defines the first hollow portion 10a, and this is recessed and deformed into the interior I side. At this time, since the hollow portion 10 is divided into the first hollow portion 10a and the second hollow portion 10b by the middle rib 19, the wall portion 20 of the seal portion defining the first hollow portion 10a is formed.
Although the inner rib 19 and the middle rib 19 are elastically deformed as shown in FIG. 1, the force applied by the door glass edge 8 is not directly applied to the rear wall 16 defining the second hollow portion 10b. It is not pulled by a large force. For this reason, the force from the door glass 2 hardly acts on the base portion 18 of the lip 12, and the lip 12 does not move so much that it protrudes from the finisher plate 13. Therefore, the lip 12 is pressed by the finisher plate 13 and stays at the position shown in FIG. That is, since the hollow portion 10 is divided into the first hollow portion 10a and the second hollow portion 10b by the middle rib 19, the movement of each of the wall portions 20 and 16 partitioning each of these hollow portions 10a and 10b is respectively. It becomes independent and almost no external force is transmitted to the lip 12.

In this way, the protrusion amount of the lip 12 is particularly increased,
Even when the lip 12 is not formed with the projection 17 or 17a (FIG. 4), the lip 12 jumps out from the inside of the finisher plate 13 when the door glass 2 is closed and the door 3 is closed with a strong force. There is no.

Further, since a large tensile force does not directly act on the rear wall portion 16 of the seal portion 9 as described above, the thickness can be reduced, and the thickness of the middle rib 19 does not need to be particularly large. Also, as shown in FIGS. 1 and 2, the finisher plate 13
When the plate 13 is arranged such that the tip 13a of the plate 13 faces the second hollow portion 10b, the effect of preventing the lip 12 from jumping out can be further enhanced.

The present invention can be advantageously applied to a weather strip attached to the front pillar 14 shown in FIG. 1 and to a center pillar, particularly a weather strip attached to a center pillar of a two-door type vehicle.

[Effect of the invention]

According to the present invention, it is possible to prevent the lip of the weather strip from jumping out from the inside of the finisher plate when the sashless door is closed by the extremely simple structure of providing the middle rib of the sealing portion of the weather strip.
