DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run supporting structure for slidably supporting a door glass of an automobile door.

[0002]

2. Description of the Related Art Conventionally, the front and rear edges of a door glass of an automobile door are vertically guided by a door frame. However, in order to guide the front edge of the door glass even when the door glass is lowered. As disclosed in Japanese Utility Model Laid-Open No. 2-71024, a lower sash is connected to the lower end of a door frame. However, in the case of a thin door having a narrow internal space, such as a door for a mini car, the gap between the lower sash and the internal mechanism of the door (for example, a door panel or a bracket for door check) becomes small, and the lower sash and the internal mechanism of the door become smaller. There was a risk of interference.

[0003] In view of this, there has been proposed a type in which only a glass run fitted into the inner periphery of a door frame is extended downward from a lower end portion of the door frame. In this case, even if the extension of the glass run interferes with the internal mechanism of the door, there is no problem because the glass run itself is formed of an elastic body.

[0004]

However, in this case, when the door glass is lowered to near the lower end position,
Due to the frictional resistance between the door glass and the glass run, there is a problem that the extension of the glass run bends forward and easily comes off the front edge of the door glass. If the door is strongly closed with the glass run off the door glass, the impact may cause the door glass to directly interfere with the internal mechanism of the door. Therefore, an object of the present invention is to provide a support structure for a glass run that can prevent the glass run from coming off the front edge of the door glass and prevent interference between the door glass and the internal mechanism of the door with a simple structure. It is in.

[0005]

In order to achieve the above object, the present invention extends a glass run downward from a lower end of a door frame, and when the door glass is lowered, a front edge of the door glass is moved to the glass run. In an automobile door slidable along an extension, a door check bracket fixed to the door is provided with a support surface for restricting the extension of the glass run from moving forward of the vehicle body.

[0006]

When the door glass is lowered, the extension of the glass run tends to bend forward due to the frictional resistance between the front edge of the door glass and the glass run. However, since the front side of the glass run is supported by the support surface provided on the door check bracket, the forward deflection of the glass run is restricted, and the extended portion of the glass run comes off the front edge of the door glass. There is no. Therefore, when the door is closed tightly,
The door glass can be prevented from directly interfering with the internal mechanism of the door.

[0007]

1 to 4 show an example in which the present invention is applied to a rear door of an automobile. In the figure, 1 is a rear door, 2 is a front door, 3 is a center pillar, and the rear door 1 can be opened and closed around a hinge point O to a position indicated by a two-dot chain line.

A door frame 5 is provided on the upper portion of the rear door 1, and a glass run 7 for slidably guiding and sealing both front and rear edges of the door glass 6 is fitted inside the door frame 5. I have. Since the rear side of the inner space of the rear door 1 has less interference than the front side, the lower end 5b on the rear side of the door frame 5 is the lower end 5 on the front side.
It extends below a. The glass run 7 is made of a known soft material such as extruded rubber or vinyl chloride,
One end of the door frame 5 extends downward from a lower end 5a on the front side of the door frame 5. When the door glass 6 is lowered to the lowermost position (shown by a solid line in FIG. 1), the front edge of the door glass 6 is slidably guided along the extension 7a of the glass run 7.

Between the center pillar 3 and the rear door 1 and near the extension 7a of the glass run 7, a door check device 10 for preventing the door from opening excessively is provided. The door check device 10 includes an arm 12 supported by a bracket 8 fixed to the rear surface of the center pillar 3 by a pin 11 so as to be swingable in a horizontal direction, and a rear door 1.
And a door operating force control unit 13 for inserting and holding the distal end of the arm 12. As shown in FIGS. 2 and 3, the door operating force control unit 13 includes a bracket 14 fixed to the inner surface of the inner panel 1 a of the rear door 1 and a cup-type housing 15 fixed to the bracket 14 with screws 9. Have. Inside the housing 15,
A pair of rollers 16 pressed against the upper and lower surfaces of the arm 12
And a collar 17 for supporting the roller 16 and a rubber 18 for urging the roller 16 in the opposite direction. When the rear door 1 is opened, the roller 16 rides over the bulging portion 12a of the arm 12 so that the opening / closing operation of the rear door 1 is given a sense of moderation and can be held at the open position. A stopper 20 is provided at the tip of the arm 12 and is prevented from coming off by a pin 19.
Is opened, the stopper 20 hits the housing 15,
An open limit position is defined.

As shown in FIG. 4, the bracket 14 is bent stepwise along the inner surface of the inner panel 1a, and has a hole 14 through which the arm 12 is inserted.
a and a screw insertion hole 14b for fixing the housing 15
Are formed. A support fitting (support portion) 21 having a substantially L-shaped cross section is fixed to the front side of the bracket 14 by means such as spot welding.

A first support surface 21a for supporting the front surface of the extension 7a of the glass run 7 and a first support surface 21a
A second support surface 21b for supporting the inner side surface of the support surface 21a is formed, and inclined surfaces 21c and 21d inclined forward are formed at upper and lower portions of the support surface 21a. Upper inclined surface 21c
Has a role as a guide surface when the glass run 7 is inserted from above the rear door 1 when the glass run 7 is assembled, so that the glass run 7 is easily assembled. It is needless to say that the support fitting 21 may be formed integrally with the bracket 14.

Further, as shown in FIG. 5, the shape of the support fitting 21 may be a U-shaped cross section to which a third support surface 21e for supporting the outer side surface of the extension 7a is added. Third support surface 21e
Is added, the extended portion 7a of the glass run 7 can be held on three surfaces, that is, the front surface and the left and right side surfaces.

In the above structure, when the door glass 6 is lowered, its front and rear edges slide downward along the glass run 7 fitted into the door frame 5. When the door glass 6 is lowered to a position near the lowermost position, the door glass 6
Due to the frictional resistance between the front edge of the glass run 7 and the extension 7a of the glass run 7, the extension 7a tends to bend forward.
a may come off the front edge of the door glass 6. However, the front of the extension 7a of the glass run 7
Is supported by the first support surface 21a of the support fitting 21 fixed to the support member 21, so that the forward bending of the extension portion 7a is restricted,
It does not come off the front edge of the door glass 6. Therefore, the front edge of the door glass 6 is always protected by the glass run 7, and interference between the door glass 6 and an internal mechanism (for example, the bracket 14 or the like) of the rear door 1 is prevented. Also,
When the rear door 1 is forcibly closed with the door glass 6 lowered to the lowermost position, an inertial force acts on the door glass 6 toward the inside of the vehicle body. , The door glass 6 is prevented from swinging inward, and the door glass 6 can be stably supported.

In the above-described embodiment, an example in which the present invention is applied to the rear door 1 has been described. However, if a door check bracket is disposed in the vicinity of the extension 7a of the glass run 7, the front door may be provided. 2 can be similarly applied.

[0015]

As is apparent from the above description, according to the present invention, the door check bracket is provided with the support surface for restricting the extension of the glass run from swinging toward the front of the vehicle body.
The extension of the glass run can be prevented from coming off the door glass, and the door glass can be prevented from directly interfering with the internal mechanism of the door when the door is strongly closed. Further, since the above function can be achieved only by partially changing the shape of the door check bracket, there is an effect that the weight is hardly increased and the cost is low.
