Description

[Detailed explanation of the idea] The present invention relates to a rattling device for automobile door glass.

In order to prevent the door glass of an automobile from rattling in the lateral direction, a rattling prevention device is provided on the inner panel of the door, and the door glass and the rattling prevention device are kept in contact with each other.

The glass contacting part of this rattling prevention device is made of a rubber surface bonded to cloth, but frictional noise is generated while the door glass is being raised and lowered.

In particular, it has been experienced that this sound becomes unpleasant and is transmitted to the user when the humidity is high.

For this reason, eliminating this abnormal noise has become a common problem for automobile door designers, but this problem has not been solved to date.

In order to solve the above-mentioned problems, the present inventor created the contact part of the rattling prevention device made of various materials, and as a result of experiments using an actual vehicle under all weather conditions, it was found that a material made of felt material with fiber cloth attached to the door It has been found that frictional noise due to contact between the glass and the rattling device is not generated.

Therefore, the object of the present invention is to provide an automobile door glass which has a felt material and a fiber cloth material stretched on the surface of the felt material, and in which the fiber cloth material is in contact with the hook of the door glass when the door glass is at its upper limit. An object of the present invention is to provide a rattling prevention device.

Preferred embodiments of the invention will now be described in conjunction with the accompanying drawings.

With reference to FIGS. 1 and 2, the movement of the automobile door glass 1 will first be described.

A door 4 is attached to an opening 3 of a car body 2 according to a conventional method.

The door 4 has a door glass opening 5 in its upper part, the door glass 1 rising and lowering into and out of the interior space 8 formed by the outer and inner panels 6.7 forming the door 4.

A bracket 9 is fixed to the lower part of the door glass 1, and upper and lower sliders 10° 11 separated from each other are further fixed to the bracket 9.

Further, a guide rod 12 whose both ends are fixed to the door 4 is provided in the interior space 8, and upper and lower sliders 10, 11 are attached to the guide rod 12.
Pass through the through hole provided in the.

The bracket 9 is connected to a window regulator 13 mounted on the inner panel 7 via a link 14.

Thus, the bracket 9 is moved up and down by the operation of the window regulator, and the glass 1 is moved in the vertical direction.

Airtightness between the door glass 1 and the interior 15 is ensured by an upper sealing material 16 provided on the side edge of the body opening 3 and both sealing materials 17.18 provided on the upper edges of the outer and inner panels 6.7. .

The door glass 1 has a complex three-dimensional curved surface that matches the exterior of the automobile, and at its upper limit position, the upper end of the glass touches the upper sealing material 16 and moves up and down so that it is pressed against the interior side. The sliding engagement between the child 10 and the guide rod 12 is such that the door glass 1 can be slightly oscillated at least in the width direction of the vehicle, allowing a complicated trajectory of movement of the door glass 1 while it is being raised and lowered. I'm letting you do it.

The door glass 1 mainly consists of an outer sealing material 17 and a board member 1.
1, the door glass moves up and down along the guide rod 12 while being supported by the guide rod 12 attached to the door inner panel 7. Therefore, when the door is closed with the door glass open, the door glass swings significantly toward the interior of the room, and the guide rod attached to the door inner panel 7]2 or other parts, causing problems such as damage to the door glass.

For this reason, a backlash preventing device 19 is provided on the inside and upper side of the inner panel 7.

As shown in FIG. 3, the backlash prevention device 19 according to this invention has a main body 2 made of metal or hard plastic material.
0, a felt material 21 fixed to the tip of the main body 20, that is, to the door glass 1 side, and a fiber cloth material covering the felt material 21 and fixed to the main body.

The felt material 21 and the fiber cloth material 22 are attached to the main body 20 by applying double-sided tape to the back side of the fiber cloth material 22, adhering felt to the tape surface, and applying double-sided tape to the other surface of the felt material 21. The fiber cloth material 22 to which the felt material 21 is attached is attached to the main body 20 together with the felt material 21.

The main body 20 has a groove 24 that opens downward, and the hook 23 engages with the hour groove 24 in which the door glass 1 takes the upper limit position.

The fiber cloth material 22 is extended into the tapered groove 24 of the main body 20, and when the hook 23 fixed to the lower part of the window glass 1 comes into contact with the groove 24 of the main body, the sound caused by the contact between the skins is suppressed. It is something.

The fiber cloth material 22 extending into the tapered groove 24 is
Only the tapered surface on the door glass side may be used.

The fibrous material extending into the groove is effective in eliminating the knocking sound between the hook and the body when the door glass assumes its upper limit position.

Since the fiber cloth material is brought into contact with the door glass through the felt material, it is possible to prevent rattling in the lateral direction, that is, the width direction of the vehicle, and to completely eliminate abnormal noise while the door glass is being raised and lowered.
