Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a weather strip used in an automobile.

[Prior Art] In a car with a frameless door such as a hard top car, a weather strip is attached along the door opening of the body, and the periphery of the door glass is pressed when the door is closed to perform sealing.

Further, in an automobile door having a door frame, a weather strip of the same kind as the above is attached along the inner circumference of the door frame, and the peripheral edge of the door glass is pressed when the door glass is closed.

FIG. 7 shows a typical example of this type of weatherstrip. A weatherstrip 5 is held by a retainer 4 along the upper half of the door opening of an automobile body.
The weather strip 5 is hollow and the sealing wall 52 facing the peripheral edge of the door glass 6 is pushed up by the peripheral edge when the door glass is closed.

By the way, the weather strip 5 is required to have excellent sealing performance, that is, waterproof performance and sound insulation performance. The improvement of the sealing property is realized by increasing the pressure contact force between the seal wall 52 and the door glass 6 or increasing the wrapping area of the peripheral edge of the door glass by the seal wall 52.

By the way, as a means for increasing the pressure contact force, for example, it is conceivable to increase the rigidity by increasing the wall thickness on both sides of the portion of the seal wall 52 that is pushed up by the door glass 6, especially on the inside of the vehicle. If the force increases, the door glass closing force and the door closing force when closing the door by closing the door glass also increase, which is not preferable. Further, as a means for improving the wrapping, it is conceivable to make the entire seal wall 52 thin so as to be easily deformed and to set a large bending allowance of the seal wall 52 by pushing up the door glass 6,
If the sealing wall 52 is too thin, the sealing performance cannot be improved even if the bending margin is large.

[Problems to be Solved by the Present Invention] The present invention has been made to solve the above-mentioned problems in a weather strip to be attached along a door opening or a door frame of an automobile body. The purpose of the present invention is to improve the sealing property of the weather strip without increasing the glass closing force.

[Means for Solving the Problems] The weather strip of the present invention comprises a mounting base for holding along the door opening or door frame of an automobile body,
A hollow weatherstrip is constituted by a side wall on the outer side of the vehicle and a seal wall connecting a tip of the side wall and a mounting base, and a part of the seal wall on the outer side of the vehicle that is pushed up by a door glass (hereinafter, outer half part). Is formed almost at right angles to the direction of pushing up the door glass, and the inner part of the car (hereinafter referred to as the inner half part) is an inclined surface that rises diagonally with respect to the direction of pushing up the door glass. None, the inner half portion is thicker than the outer half portion, and the inner half portion is bent at the root portion so that the inner half portion can be bent at the root portion.

[Effect] When the door glass is lifted and closed, the door glass pushes up the outer half of the weather strip sealing wall. Along with this, the inner half part rotates upward around the root part where the lightening is formed. Then, when the door glass rises to the closed position, the inner half portion forms an angle close to a right angle with respect to the door glass surface. On the other hand, the tip of the side wall on the outer side of the vehicle, which is connected to the outer half, is pulled inward and pushes the outer surface of the peripheral edge of the door glass. Then, the tip of the inner half portion, to which the pushing force is made thick to give rigidity, is supported from the inner surface of the peripheral portion of the door glass.

Therefore, the peripheral edge portion of the door glass is wrapped by the seal wall from both the inner and outer side surfaces together with the end surface, and the sealing property becomes good. Further, when the seal glass is pushed up by the door glass or when the door is closed at the door glass closed position, the inner half part of the seal wall rotates around the root portion, so that the door and door glass closing force hardly increases.

[Embodiment] In the first embodiment shown in FIGS. 1 to 3, the front pillar 1 and the roof side 2 of the hardtop type automobile
A weather strip 5 made of sponge rubber is attached to a door opening formed by the center pillar 3 by a retainer 4 along the door opening. As shown in FIG. 2, the weather strip 5 is fitted to the retainer 4 by a base portion 51 having a substantially U-shaped cross section. Side wall 512 of the base 51 inside the vehicle
Is hollow and extends downward, and an inner lip 53 extends from the tip. The protrusions of the retainer 4 are engaged with the recesses formed on the outer surfaces of the side wall 512 and the side wall 513 outside the vehicle. Reference numeral 7 is a trim mounted around the door opening.

The front of the bottom wall 511 of the base 51 has a V-shaped cross section, one end of which is connected to the tip of a side wall 513 outside the vehicle, and the other end is closed by a seal wall 52 that connects to the end of the bottom wall 511. 52 and bottom wall 51
The space between 1 and 1 is hollow.

The outer half portion 52a of the seal wall 52 is substantially parallel to the bottom wall 511 and is substantially perpendicular to the direction of pushing up the door glass 6, and the inner half portion 52b rises diagonally to the direction of pushing up the door glass 6. It is inclined. Inner half 52
The b is thicker than the outer half portion 52a, particularly in the root direction. However, only the root part is thinned by providing a lightening 54 on the inner side and can be bent.

In the weather strip 5 configured as described above,
When the door glass 6 rises and is closed, the above-mentioned sealing wall
The outer half portion 52a of the 52 is pushed up by the peripheral edge of the door glass. This connects the outer half 52a with the inner half 52b.
Although the outer end of the door is lifted, the inner half portion 52b rotates around its root, so there is little resistance to raising the door glass. When the door glass 6 reaches a predetermined closed position, the tip of the side wall 513 outside the vehicle is pulled inward and pushes the outer surface of the peripheral edge of the door glass 6 inward, and pivots against this. The outer edge of the thick inner half portion 52b approaching in the direction perpendicular to the door glass surface supports the peripheral edge of the door glass 6 from the glass inner surface side. It will be wrapped from the outside.

4 to 6 show an embodiment of a weather strip mounted along the inner circumference of the door frame 7, and the bottom wall 51 of the mounting base 51 having a U-shaped cross section of the weather strip 5 is shown.
Reference numeral 1 denotes a hollow shape, and a side wall 513 on the vehicle exterior side and a side wall 512 on the vehicle interior side, the tip of which forms a molding lip 514, are connected by a seal wall 52 having a V-shaped cross section. Mounting base 51
Is fitted into the door frame 7, and the side wall 512 on the inside of the vehicle, which has a U-shaped cross section with the holding lip 55, is attached to the door frame 7.
It is held on the flange 71 of the.

Of the seal wall 52, an outer half portion 52a pushed up by the door glass 6 is substantially perpendicular to the door glass pushing up direction, and an inner half portion 52b is inclined. The inner half portion 52b has a thick wall, and a lightening 54 is formed on the outer side of the root portion so as to be bendable. The outer half portion 52a of the seal wall 52 is made of sponge rubber, and the other portion is made of solid rubber.

This weather strip is also the outer half portion 52a of the seal wall 52, similarly to the weather strip mounted on the door opening of the body.
When the door glass 6 is pushed up by the door glass 6, the inner half portion 52b rotates around the root portion provided with the lightening 54, and when the door glass 6 rises to a predetermined closed position as shown in FIG. From the inner and outer surfaces, the peripheral edge of 6 is a molding lip 514.
And the inner half portion 52b of the seal wall are sandwiched and wrapped.

As described above, according to the weather strip of the present invention, the wrapping around the edge of the door glass can be increased and the sealing performance can be further improved as compared with the conventional weather strip. At the same time, since the thick inner half portion 52b of the seal wall 52 can be bent around its root, the door glass closing force and the door closing force when closing the door in the door glass closed state do not increase.
