Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a weather strip for automobiles that comes into contact with the upper part of a window glass when it is raised.

[Prior art]

When raising the window glass of a car that can be raised and lowered,
Various structures have been devised for the weather strip with which the upper part is brought into contact (for example, see Japanese Utility Model Publication No. 53-28897).

FIG. 3 shows a conventional example of such a weather strip, which is constructed as follows.

Side rail 1 installed along the vehicle width side of a car
Then, the drip rail 2 is fixed, the side edge of the roof panel 3 is fixed to the drip rail 2, and the molding 4 is attached to the outside thereof. Also, a roof trim 6 and a side trim 7 are attached to the inside of the vehicle.

A retainer 9 is fixed to the lower surface of the side rail 1, and a weather strip 1 is brought into contact with the raised window glass 10 (without a sash).
Fit 2.

The weather strip 12 is formed hollow so that its fin portion 12a receives the upper portion 10a of the window glass 10. The retainer 9 also has a fin portion 12a to prevent the glass from floating (displacement of the glass toward the outside of the vehicle) caused by negative pressure on the outside of the vehicle during high-speed driving. A pressing overhang 9a is provided.

With this configuration, the upper edge (end) of the window glass is hidden within the weather strip 12, so the appearance is good, but the contact area of the weather strip 12 with the window glass 10 is in a single row. Since there is no strong position adjustment in the vehicle width direction, there will be variations in the adjustment of the glass abutting position.
Further, there is a problem that the airtight and watertight sealing properties are also deteriorated.

[Purpose of the invention] This invention is intended to provide a weather strip for automobiles that solves the above-mentioned problems.

[Structure of the idea]

This invention has a weather strip 20 having a base 20i in the shape of a substantially square shape, a hollow part 20b at one end facing outside the vehicle, and an upper part of the window glass 10.
A fin portion 20c is formed with which the edge portion 10b of the lip portion 0a comes into contact to form a seal, and a second hollow portion 20c is formed on the other end side, which is partitioned by a partition wall 20e extending in the lip width direction from the first hollow portion 20j on the base side.

This is a weather strip for an automobile, in which the fin portion 20c and the pantograph-shaped cross-sectional portion 20g are connected by a connecting wall 20k.

〔Example〕

The details of this invention will be explained below with reference to the embodiment shown in FIG.

This configuration is similar to the conventional weather strip 12.
is replaced with a weather strip 20.

The weather strip 20 has a base portion 20i with a substantially shaped cross section, consisting of a portion fitted into the retainer 9 and a portion protruding along the indoor side of the window glass, and is connected to a partition wall 20a provided inside. , a fin portion 20c is formed with a hollow portion 20b on the inside, and the window glass 1 is raised to the fin portion 20c.
The edge portion (end portion) 10b of the upper portion 10a of 0 is brought into contact.

Further, the weather strip 20 is attached to the base 20i.
A hollow portion partitioned into a first hollow portion 20j and a second hollow portion 20f by a partition wall 20e extending in the width direction from A pantograph-shaped cross section 20g is formed by projecting to the side of the first hollow part 20j, and a lip 20h is protruded from the side of the pantograph, and this is applied to the side surface 10c of the upper part 10a of the raised window glass 10. Let them come into contact with you.

Furthermore, a connecting wall 20k is provided that connects the partition wall 20a of the fin portion 20c and the partition wall 20e of the pantograph-shaped cross-sectional portion 20g.

That is, in the upper portion 10a of the window glass 10, the edge portion 10b abuts the fin portion 20c of the weather strip 20, and the side surface 10c abuts the lip 20h of the weather strip 20, forming a double seal structure. Note that the fin portion 20c is, as in the conventional example,
The outside of the vehicle is held down by the overhanging portion 9a of the retainer 9.

[Effect of idea]

This idea is as described above, and the fins and lips of the weather strip come into contact with the upper edge and side surfaces of the raised window glass, creating a double seal structure, making it airtight and watertight. The sealing performance of the product is significantly improved.

And the fin part and pantograph-shaped cross section are
Since each is formed in a sealed hollow portion, when the upper edge and side surface of the window glass come into contact with this, the sealing pressure increases and the sealing performance is maintained well.

Regarding this, if the fin portion and the pantograph-shaped cross-sectional portion are formed independently (not connected), they will become unstable vertically and in the vehicle width direction with respect to the rising and falling window glass, which may cause them to fall over. The sealing performance will be impaired.

However, in this invention, the fins and the pantograph-shaped cross-section are integrally formed by connecting them with a connecting wall, so that they are stable in the vertical and vehicle width directions and do not fall down, and the contact position of the rising and falling window glass is stable. Even if there is a misalignment, this is absorbed to ensure sealing performance. It is also possible to prevent the glass from floating when the vehicle is running.
