The present invention relates to a vehicle door sash.
Regarding the grass run to be attached .

[0002]

2. Description of the Related Art In a side door a of an automobile shown in FIG. 4, a glass run c is mounted on a sash b to guide a door glass d up and down. As a mounting structure of the glass run c, for example, as shown in FIG. 3, hooks e, e are provided at both ends of the glass run mounting portion of the sash b, and the hooks e, e are respectively engaged with the engaging grooves f, f of the glass run c. A combination is known (see JP-A-63-43823).

[0003]

In assembling the glass run c, first, the engagement groove f of the glass run c is engaged with the hook e on the lower side of the sash b, and then the glass run c is engaged with the hook e on the upper side. The glass run c is rotated while pressing the side surface so that the engaging groove f is connected to the upper hook e.
Must be engaged. In other words, such a work must be performed over the entire length of the glass run c, which requires a great deal of trouble.

[0004] In view of such circumstances, an object of the present invention is to provide a glass run excellent in assemblability.

[0005]

In order to solve the above-mentioned problems, the present invention provides a glass run mounting portion provided with a locking portion at one end on the outside of the vehicle body, and a glass run mounting portion provided with a second end at the inside of the vehicle body. A glass run attached to a vehicle door sash having a locking portion provided with a first guide surface, and further partially raising an inner surface of the glass run mounting portion to form a second guide surface, the base comprising: A first guided portion and an engagement groove are provided at a lower end of the portion, a second guided portion is provided at an intermediate portion of the base portion, and a hook portion is provided outside the vehicle body at an upper end of the base portion. By pushing the first and second guided portions into the glass run mounting portion of the sash while abutting the guide portions on the guide surfaces of the sash, the hook portions and the engaging grooves respectively engage with the locking portions at both ends of the glass run mounting portion. Is An upper end of the base portion on the inner side of the vehicle body, which extends from the upper end to the inner side of the vehicle body, is pressed against the second guide surface when the glass run is mounted, and is bent and deformed. A first seal lip made of sponge rubber is provided, which is separated from the surface and closely adheres to the inner surface of the side wall of the glass run mounting portion.

The distance from the tip of the first seal lip to the hook when the first seal lip is pressed against the second guide surface and bent when the glass run is mounted is determined by the distance between the second guide surface and the outside of the vehicle body. May be set so as to be smaller than the distance from the locking portion.

At the upper end of the base portion inside the vehicle body,
Extends to the opposite side of the seal lip of No. 1 and attaches to a glass run
The second that adheres to the inner surface of the upper wall of the glass run mounting part when completed
May be provided.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a cross section taken along line AA of FIG.
In the figure, 1 is a sash, and the sash 1 is a plate 2
The glass run mounting portion 3 having a substantially L-shaped cross section is formed by roll molding. The glass run mounting portion 3 has a bent portion 4 formed at a side end of an upper wall 3a, and a lower end of a side wall 3b is bent into a substantially L-shape to form a locking portion 5 and a first guide surface 6.
Is formed. The second guide surface 7 is formed by partially protruding the side wall 3b. Furthermore, the upper wall 3a
, A weather strip 8 is mounted, and the tip of the weather strip 8 is wound around the bent portion 4 to form a locking portion 9.

A glass run 10 has a first guided portion 12 and an engagement groove 13 formed at a lower end of a base portion 11 thereof. Further, the glass holding lip 14 extends obliquely upward from the lower end of the base portion 11, and the first and second seal lips 15, 16 extend from the upper end of the base portion 11 to the inside and outside of the vehicle body, respectively. is there. A horizontal wall 18 is provided near the upper end of the base portion 11 with a hook portion 17, and a glass holding wall 19 is provided at an end of the horizontal wall 18. A seal bridge 20 is provided from the tip of the glass holding wall 19 to the base portion 11 to form a hollow portion 21. A second guided portion 22 is formed on a side surface of the base portion 11 opposite to the hollow portion 21. The first and second seal lips 15, 16 and the seal bridge 20 are formed of sponge rubber, and the other portions are formed of solid rubber.

When assembling the glass run 10 to the sash 1, first, as shown in FIG.
The glass run 10 is pushed up while the first and second guided portions 12 and 22 of the glass run 10 abut against the first and second guide surfaces 6 and 7, respectively, and the engagement groove 13 and the hook portion 17 are respectively moved. What is necessary is just to engage with the locking parts 5 and 9 of the sash 1 side .

In the present embodiment, since the glass run 10 is inserted into the sash 1 while guiding the glass run 10 by the two guide surfaces 6, 7 of the sash 1, the insertion direction is stable, and the insertion is easily performed. In particular, when the glass run 10 is set as shown in FIG. 2, the first seal lip 15 is pressed against the second guide surface 7 and is bent and deformed. Guide surface 7 and locking
Since the distance from the portion 9 is smaller, the upper end portion of the glass run 10 smoothly passes through this interval. However, when the insertion of the glass run 10 is started, the first seal lip 15 is moved to the second guide lip. When the second guided portion 22 comes back into contact with the second guide surface 7, the locking portion 9 and the hook portion 17 are engaged.

Furthermore, when the glass run 10 is mounted, the first and second seal lips 15 and 16 are in close contact with the side walls of the glass run mounting portion and the inner surfaces of the upper walls 3b and 3a, respectively. Even if there is a distortion or a dimensional error of the glass run 10, stable sealing performance can be ensured.

In the glass run 10 of this embodiment, when the upper end of the door glass 23 pushes up the seal bridge 20, the seal bridge 20 folds the glass holding wall 19 inward, and the tip of the glass bridge 10 contacts the surface of the door glass 23. Although it is of a so-called flash surface type that smoothly connects, the present invention is not limited to this type of glass run.

[0015]

According to the present invention, when assembling the glass run, the first guided portion of the glass run is brought into contact with the first guide surface of the sash, and the first sponge rubber is formed. By pushing the glass run into the glass run mounting portion of the sash while bending and deforming the seal lip by abutting the second guide surface, the hook portion and the engaging groove can be easily inserted into the locking portions at both ends of the glass run mounting portion. It becomes possible to engage and work becomes very easy.
