Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a weather strip for subuncle doors.

Conventional technology In sub-stress type cars, weather protection is applied to the periphery of the car body opening.
A strip is attached, and when the door is closed, the door glass is pressed against the weather strip to create a seal.

To explain this example with reference to FIG. 4, the weather strip l is formed into a hollow shape made of sponge rubber, and is attached to the roof side rail 3 with screws etc. via a retainer 2 fitted to its base. installed.

Incidentally, a decorative welt 5 is fitted onto the joining flange portion 4 of the roof side rail 3.

In addition, with the weather strip l that directly seals the door glass 6, even when the door glass 6 is moved up and down, the edge of the door glass 6 does not touch the weather strip 1.
The weatherstrip must be placed in the specified position, so it must be placed around the entire circumference of the weather strip or at key points.
A glass guide 7 is provided to guide the edge of the door glass 6 that has risen toward the interior of the vehicle.

This glass guide 7 is made of hard rubber or hard resin, and is attached to the tip of the terminal portion 2a of the retainer 2 (this similar structure is disclosed in, for example, Japanese Patent Laid-Open No. 61-222
814).

Problems to be Solved by the Invention When rainwater adhering to the edge of the door glass 6 enters between the glass guide 7 attached to the terminal portion 2a of the retainer 2 and the weather strip l, this rainwater is removed. There is a problem in that there is a risk that the water may enter the interior of the vehicle from between the retainer 2 and the base of the weather strip l and drip into the interior of the vehicle.

In addition, if the width of the attachment part of the weather strip l is partially different, it is necessary to use a weather strip with a different width, and the retainer 2 etc. must also be manufactured separately. This has the disadvantage that the number of parts and assembly man-hours increase, leading to an increase in costs.

When installing the weather strip l,
Since it is necessary to attach it while considering the positional relationship with the welt 5 and the glass guide 7, there is a problem that the attachment work is difficult to perform.

Therefore, this invention can improve watertightness,
Moreover, it is an object of the present invention to provide a weather strip for a sash-less door that can freely follow the width dimension of an attachment part and is also easy to install.

Means for Solving the Problems The present invention includes a welt part on the inside of the vehicle interior that is fitted to the joining flange part of the roof side rail, and a welt part on the outside of the vehicle interior that is fitted to the outer flange joined to the roof side rail, A trip part and a glass guide part are integrally formed in the welt part on the outside of the vehicle interior, and a hollow seal part made of soft rubber that can be expanded and contracted in the vehicle width direction is integrally formed between each of the welt parts.

A welt part on the outside of a vehicle interior provided with a working glass guide part and a hollow lip part are integrated to prevent rainwater etc. from going around between the glass guide part and the hollow lip part.

Additionally, when installing, the entire installation can be done at once by fitting the welt part on the inside of the vehicle interior into the joining flange of the roof side rail, and fitting the welt part on the outside of the vehicle cabin into the outer flange. At the same time, the hollow seal portion expands and contracts to freely respond to changes in the mounting width.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

1 to 3, the roof side rail 3 is formed from an inner panel 8 and an outer panel 9 to have a closed cross-sectional structure, and is provided with a joining flange portion 4. As shown in FIGS. On the other hand, an outer flange 10 is joined to the outer surface of the outer panel 9, and an end portion of the roof panel 11 is joined to the outer flange 10 to form a flange portion I2.

A weather strip l is attached to the joining flange portion 4 and the flange If2.

The weather strip l consists of a welt part 13 (made of hard rubber) on the inside of the passenger compartment fitted to the joining flange part 4 and a welt part 1 on the outside of the passenger compartment fitted to the flange part 12.
4 (made of hard resin), and these welt parts 1
3 and the welt part 14, a hollow seal part 15 made of sponge rubber, which is a soft rubber product, is integrally formed.

Note that the welt portions 13, 14 and the hollow seal portion 15 are simultaneously molded by extrusion molding.

The strength of the welt portion 13 on the inside of the vehicle interior is ensured by a U-shaped core bar 13a, and an extension portion 13b that covers the hollow seal portion 15 is provided on the inner edge. Note that a cloth 13c is attached to the surface of the welt portion 13.

On the other hand, the welt portion 14 on the outside of the vehicle interior has a U-shaped core bar 14a.
The strength is ensured by
A glass guide portion 14d that holds the door glass 6 is integrally formed between the trip molding portion +4c forming the trip molding portion 114b and a hollow seal portion 15 to be described later. Incidentally, a core metal 14a is also embedded in a portion extending from the trip molding portion 14c to the glass guide portion 14d.

The hollow seal portion 15 wraps around and seals the edge of the door glass 6, and the distance between the flange portion 4 of the joint 7 and the flange portion 12 (
It can be expanded and contracted in response to changes in the width of the mounting area, so that it does not interfere with installation.

In addition, a water collection groove 15 is provided between the roof side rail 3 and the roof side rail 3 on the side of the bellows portion 15a that faces the roof side rail 3.
b is formed.

A seal lip 16 made of sponge rubber is formed on the outside of the base of the welt portion 13 and on the inside and outside of the base of the welt portion 14.

According to the structure of the above embodiment, there is no room for water to enter between the glass guide part 14d and the hollow seal part 15 as in the conventional case, and watertightness can be further improved. Also,
Regarding watertightness between the roof side rail 3 and the roof side rail 3, the trip portion 14b allows water to drain smoothly, and the sealing action of the seal lip 16 prevents water from entering the interior of the vehicle. Even if the water flows around, the water is guided downward by the water collection groove 15b provided between the bellows part 15a of the hollow seal part 15 and the roof side rail 3, so that it does not reach the inside of the vehicle.

In addition, the weather strip l has both welt parts 13 and 14.
All installation can be done just by fitting the hollow seal part 1, which improves the efficiency of the installation work.
Since the bellows portion 15a of No. 5 can follow changes in the distance between the joining flange portion 4 and the flange portion 12, even if the distance increases as shown in FIG. 2, the installation work will not be hindered.

And the welt part for the hollow seal part 15! 3.14
Since the trip molding part 14c and the glass guide part 14d are integrated, the number of parts is reduced and there is no need to adjust the relative position of each part (and since it can be set accurately, adjustment work is required at the time of installation. It is advantageous in that it disappears.

As described in detail, according to the present invention, there is no room for water to enter between the glass guide part and the hollow seal part, so watertightness is improved compared to the conventional method in which the glass guide part and the hollow seal part are attached using a retainer. It has the effect of being able to improve the

In addition, even if the width of the mounting area changes partially, the hollow seal part, which is configured to be expandable and retractable, can be freely adjusted, making it possible to respond flexibly with the same parts. There is.

In addition, since the installation can be carried out by simply fitting both welt parts to the joining flange and the outer flange of the roof side rail, work efficiency can be improved.

In addition, since it is a single part, it has the functions of conventional welts, glass guides, and trips, so it has the effect of reducing the number of parts and significantly reducing costs.
