Abstract

PURPOSE:To prevent the slight vibration of a door glass in high-speed traveling by installing in projection a small lip which is arranged lower than the upper edge of the door glass in closing at one edge of an outer sealing lip and contacts with the upper edge of the door glass, pressing it to the car-interior side. CONSTITUTION:A weather strip body 11 is supported by a retainer 12 and fixed onto a chassis side. Said body 11 has a main sealing lip 11a positioned on the car-interior side and an outer sealing lip 11b positioned outside the car-interior side, and a glass guide 11c is installed onto the necessary part of the outer sealing lip 11b. With such constitution, a small lip piece 16 is installed in projection at one edge of the outer sealing lip 11b. Said small lip piece 16 is arranged lower than the upper edge of a door glass 15 in closing, and contacts with the upper edge of the door glass 15 in closing so as to press it onto the car interior side. Therefore, the slight vibration of the door glass 15 on high-speed traveling can be prevented.

Description

[Detailed Description of the Invention] (Field of application in the industry) The present invention is directed to a body side weathering system for use in front and rear vehicles.
The present invention relates to a weather strip, and particularly to a weather strip structure that prevents door glass from vibrating slightly due to negative pressure generated when a vehicle is running at high speed.

(Prior art) The conventional body side weather strip used only by Satsu/Ures has been devised to ensure that the door glass that contacts the weather strip is in the correct position. The stability of the system is measured. For example, the car body opening of the vehicle shown in Figure 1! 2iclI
A body side weather strip 5 shown in FIG. 2 is fixed between the upper end of the layered door 3 and the door glass 4 that can be raised and lowered from the door 3 and the vehicle body opening 2. As shown in FIG. In the figure, 6 is a retainer that supports the weather strip. The body side weather strip 5 includes a main knoll lip 5a located on the side of the single room relative to the door glass 7 when closed, and an outer knoll lip 5b located sub-outside of the door glass 7 when closed. A glass guide 8 is provided protruding from one end of the seal lip 5b. According to the above configuration, the upper end of the door glass 7 when closed is
It is held between the main knob lip 5a and the outer lip 5b, and when the door glass 7 shows a movement toward the outside due to the negative 1'E generated on the outside of the vehicle during high-speed driving, the outer 7-Ruritubu 5
b and the glass guide 8 act to exert a force that attempts to return the door glass 7 to its normal position.

However, such a conventional body side weather strip structure has a drawback in that it cannot completely prevent the minute vibrations of the door glass caused by negative pressure during high-speed driving. The door glass can be raised and lowered from the door body, so in order to maintain the ease of raising and lowering the door glass, it is given a slight degree of freedom, and as a result, the negative pressure during driving causes slight vibrations to the outside of the vehicle. , "katakana" sounds and other noises will be generated. In particular, the outer seal lip is made of a material with good 7tiIIJN properties, such as sponge, to absorb variations when the glass is installed.
C1 is usually molded using soft soda rubber, etc.
The inner lining prevents minute movements in the elastic region.

(Object of the Invention) The present invention eliminates the drawbacks of the conventional body-knit weather strips for cars such as those described above, and
The object of the present invention is to provide a body side weather strip that does not cause minute vibrations of the door glass during high-speed driving and also does not cause any hindrance to the door opening/closing operation.

(Structure and operation of the invention) In order to achieve the above object, the present invention provides a body side weather strip having the above-described structure, which is located at one end of the outer knoll lip below the upper end of the door glass when closed. The main object of the present invention is to obtain a body side weather strip for a non-slip vehicle, characterized in that a small lip is protruded from the outside of the upper end portion of the door glass to press against the door glass. With the above structure, the small lip 'C1 acts to prevent minute movement of the door crow due to negative pressure.

(Example) Examples of Akira Kimi will be described below based on the drawings.

Figure 3 shows a body side weather strike I that is compatible with the present invention.
The main part of the J-tube is shown in cross section, and in the figure, 11 is a weather strip main body, 12 is a retainer, and the weather strip main body 11 is supported by the retainer 12 and fixed to the vehicle body side.

The weather I-IJ knob body 11 is attached with a main knoll lip 11a located on the passenger compartment side and an outer seal lip 1.11) located on the outside of the vehicle, and hollow portions 13 and 14 are perforated. This provides cushioning properties. 11 (+ is a glass guide provided in the main part of the outer seal lip 11b, 15
indicates the position of the door glass when closed.

Furthermore, in the present invention, the outer seal lip o
A special feature is that a small lip 16 is protruded from one end of b. This small lip 16 is located lower than the upper end of the door glass position when closed, which is indicated by 15, when viewed horizontally,
Further, the upper end of the door glass 15 is in contact with the upper end of the door glass 15 so as to be pressed toward the passenger compartment side when the door glass 15 is closed.

Since the outer seal lip tib is usually made of a soft material such as sponge, the small lip 16 may also be formed integrally with the same material, or may be made separately using a hard material such as solid rubber. The outer seal lip 11b may be fixed in contact with the outer seal lip 11b along the longitudinal direction.

The operation of the body side weather strip having the above structure is as follows. That is, arrow A shown in FIG. 3 indicates the direction in which the door glass is pulled by negative pressure on the outside of the vehicle during high-speed driving, and arrow B indicates the trajectory of the upper end portion of the door glass 17 when opening and closing the door body of the vehicle. It shows.

Therefore, when the upper end of the door glass is pulled toward the outside of the vehicle due to negative pressure at high speed, the small lip 16 functions as a stopper to prevent minute movement of the door glass. On the other hand, vehicle doors are generally designed to rise near the opening of the vehicle body when they are "closed", and this increases the stability when closing, so they draw a trajectory like arrow B. When the upper end of the door glass 17 moves, the small lip 16 does not interfere with the door glass, does not cause trouble in opening and closing the door, and there is no risk of damaging the small lip 16.

(Effects of the Invention) As explained in detail above, the present invention is such that the outer seal lip is located at one end of the outer seal lip below the upper end of the door glass when closed, and presses the door glass from the outside of the upper end portion of the door glass. Since a small protruding lip is provided to abut against the door glass, the door glass has the effect of increasing the stability of the door glass during high-speed driving.

In other words, even if the door glass is pulled toward the outside of the vehicle due to the negative pressure generated when the vehicle is running at high speed, the small lip tightly contacts the top edge of the door glass to prevent minute movement of the door glass and reduce vibration. The occurrence can be eliminated. Therefore, the generation of noise caused by the above-mentioned vibrations is eliminated, and quietness during high-speed running is maintained satisfactorily, and stability is improved. Furthermore, the small lip does not become a hindrance during the opening/closing operation of the door and is not damaged, so it can perform its function for a long period of time. By forming the small lip using another member such as hard rubber, the stopper performance is further improved.

As described above, the weather strip according to the present invention is as follows.

It is mainly characterized by a structure that prevents the door glass from vibrating slightly during high-speed driving, and is highly effective when applied to body side weather strips for Saratsuyuless cars.
