[0006]

In the above-described side door portion, since the rib 500 performs a sealing function, when the window glass G is completely closed, the window glass G is moved through the glass run molding 100. There is a problem that a collision with the frame F at a considerable speed may cause an impact or an abnormal sound due to the collision between the window glass G and the frame F.
In particular, recently, since an electric power window has been adopted, the rising speed of the window glass is large, and the above-described impact and abnormal sound have become problems.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided:
In an automotive glass run molding having a base portion extending in a band shape and trim portions at both ends in the width direction of the base portion and having a corner portion, at least on the inner side surface of the base portion of the corner portion, along the longitudinal direction of the base portion. A glass run molding characterized by extending two ribs having different heights, a base portion extending in a strip shape, and a trim portion at both ends in the width direction of the base portion according to claim 3, wherein a corner portion is provided. In the glass run molding for automobiles, three ribs having different heights are extended at least along the longitudinal direction of the base at the inner surface of the base at the corner, and the rib at the center is located on both sides of the corner. The above problem was solved by glass run molding, which is characterized by being higher.

[0008]

The window glass inserted into the receiving space of the glass run molding first comes into contact with the higher rib to reduce the ascending speed, and finally stops at the lower rib. . Thus, the windowpane will be held between the high and low ribs. Claim 3
In the configuration described above, even if the window glass is biased toward the indoor side, the window glass is stopped by being received by the lower rib, so that the window glass does not collide with the base portion and does not generate a collision sound.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A glass run molding according to the present invention is mounted on an inner peripheral edge of a frame F of a side door portion of an automobile as shown in FIG.
Its overall shape is as shown in the side view of FIG.

FIG. 1 is a partially enlarged perspective view of the glass run molding of the present invention, and corresponds to a portion indicated by reference numeral X in FIG. 2 shows a cross section of each part in the perspective view of FIG. 1. FIG. 2 (a) is a cross-sectional view taken along line aa of FIG. 1 in a state where a window glass G is received, and FIG. FIG. 2C is a sectional view taken along the line bb of FIG. 1 in a state where the glass G is not received.
FIG. 2 is a sectional view taken along the line cc of FIG. 1 in a state where a window glass G is received. Although FIG. 2 shows the glass run molding 10 in a state where it is not elastically deformed, for convenience of explanation,
Actually, each part of the glass run molding 10 is elastically deformed for mounting on the frame F and receiving the window glass G.

In the glass run molding 10, for example, as shown by reference numeral A in FIG. 5, a portion forming a gentle curved portion or a straight line portion has a configuration shown in a sectional view of FIG. I have. The portion shown in FIG. 2A is, like the conventional one, a base portion 20 extending in a band shape substantially parallel to the end face of the window glass G, and the base portion 20 from both ends in the width direction to the base portion 20. Two trim portions 30a, 3 extending at an angle slightly larger and slightly smaller than a right angle, respectively.
0b, a receiving space 40 for receiving the window glass G is formed by the base portion 20 and the trim portions 30a, 30b, and extends diagonally upward into the receiving space 40 at the tip of each of the trim portions 30a, 30b. Seal rib 32
a, 32b are formed. Also, two upper engaging pieces 24a, 24b projecting obliquely outward and upward from both ends in the width direction of the base portion 20, and two lower engaging pieces extending obliquely downward from the distal ends of the trim portions 30a, 30b. 34a,
34b are respectively engaged with predetermined engagement portions of the frame F and are attached to the frame F.

In the glass run molding 10, the start and end portions of the corners indicated by reference numerals X and Y in FIG. 5 have a configuration shown in the sectional view of FIG. 2B. The basic configuration of the corner portion of the glass run molding 10 is the same as the above-described curved / straight portion, but the inner surface of the base portion 20 extends along the longitudinal direction of the base portion 20 with respect to the base portion 20. A deceleration rib 50 extending substantially at right angles into the receiving space 40, and a thick stopper rib 60 extending obliquely from the base of the deceleration rib 50 are formed. The height of the deceleration rib 50 is higher than that of the stopper rib 60. Is also higher.

The glass run molding 10 is formed by connecting the respective portions after the above-mentioned corner portions X and Y and the curved / straight portion A are formed separately, and the symbol S in FIG. Part is shown.

Next, the glass run molding 10
The deceleration ribs 50 and the stopper ribs 60 formed at the corners are described below with reference to FIG. FIG. 3 is a sectional view of the start and end portions of the corner portion X. In FIG. 2B, the window glass G is inserted into the receiving space 40, and the deceleration rib 50 and the stopper rib 60 are inserted.
It is sectional drawing which shows the state which has elastically deformed.

The window glass G rises, and the trim portions 30a, 3
0b, two seal ribs 32a, 32b formed at the tip
When entering the receiving space 40 through the gap, the end face of the window glass G first comes into contact with the deceleration rib 50 formed at the corner. When the window glass G further rises, the deceleration rib 50 is elastically deformed to generate an elastic repulsive force, so that the rising speed of the window glass G is reduced, and the end face of the window glass G has the deceleration rib 50 and the stopper rib 60. It stops in the state of having entered between.

As described above, in the state shown in FIG. 3, since the two ribs 50 and 60 are elastically deformed, the window glass G
The end faces are securely sealed. In this embodiment,
In order to bias the window glass G toward the outdoor side, the deceleration rib 50 is provided on the indoor side, and the stopper rib 60 is provided on the outdoor side.

Next, a glass run molding 12 according to a second embodiment of the present invention shown in FIG. 4 will be described. 4 is a cross-sectional view of a portion corresponding to a cross-sectional view taken along the line bb in FIG. 1 and shows a state in which the window glass G is not received. The glass run molding 12 is the same as that of the first embodiment except for the configuration of a deceleration rib and a stopper rib, which will be described later, and therefore the description of the entire configuration is omitted.

A deceleration rib 50 having the same shape as that of the first embodiment is provided on the inner surface of the base portion 20 of the glass run molding 12, and two stoppers on the both sides of the deceleration rib 50 are provided on the indoor side and the outdoor side. Ribs 60a and 60b are formed.

The above-mentioned glass run molding 12 comprises:
Even when the window glass G rises in the receiving space 40 toward the indoor side or the outdoor side, the end face of the window glass G is pressed against one of the indoor side rib 60a and the outdoor side rib 60b and surely. In addition, since the window glass G does not directly collide with the base portion 20, the generation of collision noise is reliably prevented.

In the above description, only the corner portions X and Y have the deceleration rib 50 and the stopper ribs 60, 60a,
Although the case where 60b is formed is shown, both ribs may be formed over the entire length of the glass run moldings 10 and 12.

The location to which the glass run moldings 10 and 12 of the present invention are applied may be any door portion that is opened and closed by moving the window glass G up and down, and is limited to the side door portion. Not something.

[0022]

According to the above construction, the glass run molding of the present invention can reduce the rising speed of the window glass by the high deceleration rib which first comes into contact with the window glass, so that the window glass can be moved at a high speed. There is no collision with the base. As a result, there is an effect that generation of a collision sound between the window glass and the frame can be prevented. Also, since the end face of the windowpane enters between the two ribs,
The window glass can be deeply received in the receiving space, and the sealing performance is improved, and the waterproof and soundproof properties are excellent.

Further, when the low ribs are provided on both sides of the high ribs as described in claim 3, even if the window glass is biased toward the indoor side in the receiving space, the end surface of the window glass is high. There is an effect that the rib is reliably pressed against the lower rib and the generation of collision noise can be prevented.

In addition, since a relatively simple configuration in which ribs having different heights are provided on the base portion can be used, the manufacturing cost can be suppressed, and the upper stopping point of the window glass can be brought near the frame. This has the effect of increasing the degree of freedom in setting the glass pinch detection system.
