Description

[Detailed description of the invention] The present invention relates to a weather strip for an automobile door, and in particular, to a weather strip for a vehicle door.
This invention relates to a weather strip that is suitable for use on surfaces and has improved sealing performance.

In the case of automobiles, generally, as shown in FIGS. 1 and 2, a weather strip 4 is provided on the entire periphery of the door 1, extending from the periphery of the door body 2 of the automobile door 1 to the periphery of the door sash 3. , when the door 1 is closed, this weather strip 4 is attached to the vehicle body opening edge 5.
It is placed in close contact with the surface to seal the interior and exterior of the vehicle from water, dust, and sound.

However, when applying the flash surface technique, which has recently been widely adopted from a technical and design perspective, to automobile doors, the weather strip 4 and the door glass run 7, which also serves as a seal for the door glass 6, are The installed door sash 3 is not exposed to the outer surface of the vehicle and is provided inside the door glass 6. Even in such a flat surface door, special measures are required to reliably seal the interior and exterior of the vehicle in relation to the vehicle body and the door glass.

Therefore, the object of this invention is to provide a weather strip for automobile doors that is more suitable for flash surface doors and has excellent sealing performance.

To summarize this idea, a main lip that elastically comes into close contact with the edge of the opening of the car body that is exposed to the car body side when the car door is opened is installed in the channel provided on the inside of the car rather than the door glass of the car door. A sub-rip provided on the outside (outward from the vehicle interior) and elastically abutting against the inner surface of the door glass; and a substantially concave launch channel attached to the channel extending outward from the end on the vehicle body side and extending outward from the inner surface of the door glass. This weather strip consists of an auxiliary lip that elastically abuts against the vehicle body, and is reliably sealed with the main lip, and double-sealed with the door glass by the sub-rip and the auxiliary lip.

Preferably, the main lip and the sub-lip are integrally molded, and the cross section of the integral body is approximately V.
Shape like a letter. This has the advantage that when the door is closed, the two sides of the V-shape are pressed so as to become narrower, and the elastic reaction force against this pressure increases the adhesion of the seal.

The present invention will be explained below based on the embodiments shown in FIGS. 3 and 4.

3 is a longitudinal cross-sectional view of the roof side rail portion corresponding to the cross section taken along line A-A in FIG. 1, and FIG. 4 is a cross-sectional view of the center pillar portion corresponding to the cross-section taken along line B-B in FIG. It is.

As can be seen from FIG. 3, the outer surfaces of the roof side rails 9 provided on both sides of the roof panel 8 are aligned with the surface of the front door glass 6f to form a flat surface, and as can be seen from FIG. The outer surfaces of the front door glass 6f and the rear door glass 6r are also aligned flush to form a flat surface. Therefore,
The channel 10 supporting the weather strip is
The channel 10 is located on the inner side of the vehicle interior than the door glass 6f, and as can be seen from FIGS. 3 and 4, is provided at the peripheral edge of the door glass 6f, and both ends of the channel 10 enter the bottom side of the door 1, although not shown. and door body 2 (first
(see figure).

A weather strip made of an elastic material such as rubber is fixed to the channel 10 at its base. Main lip 11 forming part of the weather strip
has a bulging shape facing inward to the vehicle interior, and when the door is closed, the vehicle body opening edge 12 at the bottom of the roof side rail 9
and the vehicle body opening edge 1 on the side of the center pillar 13
4 and seals between it and the vehicle body. A sub-rip 15 is provided on the outside of the main lip 11, that is, on the side closer to the door glass 6f, and extends toward the door glass 6f and whose tip end elastically abuts against the door glass 6f. sublip 1
5 seals between the inside and outside of the vehicle interior, that is, between the door glass 6f and the channel 10. However, considering the importance of the seal, it is secondary to the main lip 11.

In a preferred embodiment, the main lip 11 and the sub-rip 15 are formed into a single piece having a substantially V-shaped cross section, and are fixed to the channel 10 by providing an enlarged portion at the base thereof. By doing this, when the door is closed, the main lip part 11 and the sub-rip part 15 are pressed so that they become narrower, so the opening edge 12,
14 and the glass 6f, and the sealing performance can be further improved.

Next, the door glass 6f is supported by the channel 10 via a bracket 16, as shown in FIG. That is, the door glass 6f is fixed to the L-shaped bracket 16 with decorative screws 17, and a screw 18 is fixed to the bracket piece facing inward to the passenger compartment in a direction substantially parallel to the glass surface, and a large screw 18 formed at the tip of the screw 18 A diameter portion 19 is slidably supported by the channel 10. The large diameter portion 19 is fitted into a concave groove 22 formed by a rubber member 21 fixed in the same concave shape to the inner periphery of a lunch channel 20 formed in a concave shape. Therefore, when the door glass 6f moves up and down, the lance channel 20 or the groove 22
serves as a guide for the door glass. Note that a reinforcing metal core 23 may be embedded inside the concave rubber member 21. However, only the guide portion that requires a core metal is sufficient, and it is not necessary in a portion where a guide portion is not constituted as shown in FIG.

A lip portion 24 is provided integrally with this rubber member 21 having a concave cross section. The lip portion 24 is formed to curve at a slightly acute angle from the edge of the rubber member 21 near the door glass 6f, extend toward the door glass 6f, and come into elastic contact with the door glass. This lip portion 24 forms an auxiliary lip that comes into close contact with the inner surface of the door glass 6f to supplementally seal the inside and outside of the vehicle interior (when viewed from the sub-rip 15), but it is a part of the weather strip of the present invention. include.

If you configure the weather strip in this way,
When the door is closed, the main lip 11 touches the vehicle body opening edge 12,
Since both the sub-rip 15 and the auxiliary lip 24 provide a double seal with the door glass 6f, sufficient sealing performance can be ensured.

Note that thin moldings 6m, 6m may be applied to the edges where the door glasses 6f, 6r meet to seal the space between the front door glass 6f and the rear door glass 6r.

As is clear from the above, according to this invention, the main lip that is in close contact with the opening edge of the vehicle body creates a seal between the main lip and the vehicle body, and the sub-rip and auxiliary lip that are in close contact with the door glass provide a double seal between the lip and the door glass. Since it is designed to seal, it is possible to exhibit excellent sealing performance in the flat surf S door.
