Description

[Detailed Description of the Invention] This invention relates to an improvement in the structure of an automobile weather strip.

Conventionally, for example, in a hard-top automobile 1 without a door sash as shown in FIG. 1, a weather strip is attached to the peripheral edge of an outer panel 2 at the opening of the vehicle body, which contacts the door glass 4 of the door 3 via a retainer. This prevents rainwater, dust, etc. from entering the vehicle interior through the space between the door glass 4 and the outer panel 2 (see Japanese Utility Model Publication No. 134313/1983).

However, when driving at high speed with the door glass 4 closed, negative pressure is generated on the outside of the door glass 4, so if the support rigidity of the weather strip is small, the door glass 4 will be sucked outward by the negative pressure. This may cause a gap to form between the upper end surface of the door glass 4 and the lip of the weather strip, which may cause air to be sucked out of the vehicle interior or wind noise from outside the vehicle to enter the vehicle interior. There's a problem.

For this reason, a weather strip has been proposed that has a function to prevent the door glass 4 from being sucked out, but if this function is emphasized, the weather strip will act as a resistance when the door 3 is opened and closed, making it difficult to open and close the door smoothly. There was a problem that there was no.

This idea was made in view of the above-mentioned conventional problems, and includes a first lip part that comes into contact with the retainer and a second lip part that comes into contact with the pillar or pillar garnish on the outer lip part of the weather strip. This device enables smooth opening and closing operations in the opening and closing directions, and also prevents the door glass from being sucked out outward by the first and second lip parts pressing the retainer and pillar in the suction direction. This is what I did.

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

As shown in Figure 2, the weather strip W
is formed into a hollow shape by extruding an elastic material such as rubber or synthetic resin, and the mounting base 7 is inserted into the U-shaped grooves 6a and 6b on both sides of the retainer 6 attached to the pillar outer panel 2. It fits into the protrusions 7a, 7a formed on both sides, while the outer lip part 8 on the outside of the vehicle body and the inner lip part 9 on the inside of the vehicle body.
It has a lip part 10 that connects the outer lip part 8 and the inner lip part 9, and a bending bridge 12 that traverses the hollow part 11 and connects the inner surface of the mounting base 7 and the inner surface of the lip part 10. The first portion 8 is provided with a first portion that contacts the retainer 6.
A first lip portion 13 having a pressing surface 13a, and a second lip portion 13 having a second pressing surface 14a that comes into contact with the pillar outer panel 2 (or pillar garnish) 2.
A lip portion 14 is formed.

If the first lip part 13 and the second lip part 14 are made almost flush with the pillar outer panel 2 without providing a step, there will be no wind noise due to the rectification effect and it will be advantageous for air resistance etc. .

When the door glass 4 is fully closed and the door 3 is closed, the upper end surface of the door glass 4 comes into contact with the lip portion 10 of the weather strip W, as shown in FIG. The portion 10 is curved inward of the hollow portion 11, and the upper end surface of the door glass 4 and the lip portion 10 of the weather strip W are held airtight by the elasticity of the weather strip W.

When the door glass 4 is fully closed, when the door 3 is operated in the opening/closing direction A, only the outer lip portion 8 provides resistance, and the opening/closing operation can be performed smoothly.

On the other hand, when the door glass 4 is fully closed and when driving at high speed, when a suction force in the suction direction B is applied to the door glass 4, the weather strip W that is in elastic contact with the upper end surface of the door glass 4 also It tries to deform in the suction direction, but the first lip part 1
The first pressing surface 13a of the pillar outer panel 2 presses the retainer 6, and the second pressing surface 14a of the second lip part 14 presses the pillar outer panel 2.
14 restricts the deformation and prevents the door glass 4 from being sucked out.

As is clear from the above explanation, this invention is based on the outer lip of the weather strip.
Since it is provided with a first lip part and a second lip part that contact the retainer and the pillar, respectively,
The door glass can be opened and closed smoothly in the opening and closing direction, and at the same time, in the suction direction, the deformation of the weather strip is restricted by contact with a retainer, etc., and the weather strip is prevented from being sucked out. Become,
The suction prevention function will also be guaranteed.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) In the structure of an automobile weather strip in which a weather strip for sealing between the door glass and the vehicle body is fixed to the opening edge of the vehicle body via a retainer, The outer lip portion of the lip is provided with a first lip portion having a first pressing surface that contacts the retainer, and a second lip portion having a second pressing surface that contacts the pillar or pillar garnish. The first and second lip parts press the retainer and the pillar to prevent the door glass from being sucked out by the negative pressure generated during high-speed driving with the door closed. The structure of an automobile weather strip. (2) The structure of a weather strip for an automobile according to claim 1, wherein the first and second lip portions are substantially flush with a pillar or a pillar garnish.
