Abstract

PURPOSE:To prevent the occurrence of a step difference by interposing the projecting curve-like edge in the upper front between the front perpendicular edge guided by a groove of a door mirror base and the upper front inclined edge to be elastically contacted with the upper end and an inside surface of a hollow sealing part, and sealing the hollow sealing part by smoothly changing it almost in parallel to the projecting curve-like edge. CONSTITUTION:The projecting large curve-like edge is formed in the upper front- between the front perpendicular edge 21 guided by a groove of a door mirror base 40 of door glass and the upper front inclined edge 22 to be elastically contacted with the upper end and an inside surface of a hollow sealing part 32. Since a tip sealing part A point of a door weather strip 30 can be gently set by a shape change over an upper end elastically contacting part of the door mirror base 40 from an elastically contacting part of the door glass upper front inclined edge 22, even if longitudinal directional dispersion of accuracy of fittings is caused, it is easily followed up, and a step difference is hardly caused, and sealing performance is not spoiled. Even if the door glass is raised in a door opening condition, it does not rise up to the uppermost part, and rises for several seconds after a door is closed, and enters between the hollow sealing part 32 and an outside lip 35.

That is, 31 is a base portion fitted into the retainer 15, 32 is a hollow seal portion which makes elastic contact with the tip and the outer surface of the door glass 20, and is integrally connected to the vehicle exterior side of the base portion 31 and The outer surface is the front pillar portion 11
It is located along the inner surface of the mall 16 hung vertically. Reference numeral 33 denotes an inner seal structure integrally connected to the vehicle interior side of the base portion 31, and includes the base portion 31, a base portion 34 protruding downward, and a lower end of the base portion 34 and an inner surface of the door glass 20 protruding outside the vehicle. The seal lip 35 is elastically contacted, and the interior lip 36 is provided at the lower end of the base 34 and protrudes toward the inside of the vehicle to cover the flange 12. The molding 16 is integral with the retainer 15 and is formed by extending the retainer 15 to the outside of the vehicle and bending it. Reference numeral 40 denotes a door mirror base that is attached to the front side of the front pillar 11 and the corner portion where the door waist line intersects, and the door side.

In the present invention, the door glass 20 to be improved will be described. A front vertical edge 21 which moves up and down by being guided by a groove provided in a rear vertical portion of a door mirror base 40, and a weather strip 30 when it rises. Upper front slanted edge 22 to be elastically contacted with the inner surface of the hollow seal portion 32 of
have.

Further, the door glass 20 has a dropping function to prevent the door glass 20 from hitting or catching the molding 16 and the hollow seal portion 32 when the door glass 20 is opened and closed while the door glass 20 is raised. It is equipped with and is designed to operate as follows.

That is, even if the door glass 20 is lifted while the door is open, the door glass is still 5 to 20 from the top.
Only when the door is closed, the door glass 20 rises after a few seconds and the hollow seal portion 3
2 and the seal lip 35, and come into elastic contact with both,
It is designed to be fully closed.

At this time, the door glass is slightly displaced inside the vehicle by the hollow seal portion 32. Further, when the door glass 20 is raised most and the door lever is pulled to open the door, the door glass 20 is lowered by 5 to 20 mm, and then the door is opened.

However, when the door glass 20 of the above-mentioned conventional sashless vehicle is closed while the door glass 20 is raised, the door glass 20 is projected upward and forward between the front vertical edge 21 and the upper front inclined edge 22. The curved edge 23 has a small radius R _1, and the point A of the weather strip tip seal portion suddenly changes in shape from the elastic contact portion of the front inclined edge 22 of the door glass to the upper elastic contact portion of the door mirror base. Therefore, it is difficult to follow the building variations in the vehicle front-rear direction, and a step is likely to occur,
There is a problem that the sealing property is impaired.

[0009]

The problem to be solved is that the door glass 20 of the conventional sashless vehicle described above is
When the door is closed in a state where the door glass is lifted, the curved edge 23 protruding upward and downward between the front vertical edge 21 and the front slanted edge 22 is small, and the weather strip tip seal portion A point is the door glass. Since the shape from the upper front slanted edge elastic contact part 21 to the upper end elastic contact part of the door mirror base suddenly changes, it is difficult to follow the building variation in the vehicle front-rear direction, a step is likely to occur, and sealing performance is improved. To be damaged.

[0010]
