Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run for an automobile which is mounted on a grooved sash of an automobile door and holds and guides a vertically moving glass.

[0002]

[Related Art] Front door 1 of an automobile as shown in FIG.
The cross-sectional shape of the glass run 14 mounted on the second grooved sash 16 was, for example, as shown in FIG.

A run main body 18 having a channel cross section fitted and mounted in a grooved sash 16 and a pair of slides which project from the tips of both side walls 20 and 22 of the run main body 18 toward the groove bottom side. This is a configuration including lips 24 and 26. A lubricating layer 28 made of a urethane coating or the like is formed on each surface of the run body 18 and the sliding lips 24 and 26 against the glass.

Although the glass run 14 in FIG. 2 shows a cross section on the roof side taken along line 2-2 in FIG. 1, the cross sections of the glass run 14 on the front and rear pillars are basically the same. .

[0005] When the glass run is mounted on an automobile and the vehicle runs, a rattling sound (rattle sound) may be generated due to the vibration of the elevating glass 30. This can be attributed to variations in the molding of the channel sash 16 and / or the elevation glass 3.
This is because the holding force of the sliding lips 24 and 26 of the elevating glass 30 is not sufficient due to the variation in the mounting of 0 (usually 2 to 3 mm). The vibration of the elevating glass 30 is caused not only by the vibration of the automobile itself but also by the suction / return phenomenon of the elevating glass 30 when the automobile is running at high speed.
Alternatively, it also occurs at the time of opening / closing of the half-open door of the elevating glass 30.

For this reason, conventionally, as shown by a two-dot chain line,
Protrusions 3 are provided on the inside of the leading ends of the sliding lips 24 and 26 and / or on the inside of the side wall facing the leading ends of the sliding lips 24 and 26.
2, 33 are formed (Jpn.
7, Japanese Utility Model Publication No. 50-12804, etc.).

[0007]

However, in the case of the above structure, when the elevating glass is to be stored, the raising / lowering load of the elevating glass 30 at the time of elevating the elevating glass 30 is increased due to the flattening action of the flattening ridges 32 (33). There was a fear. This means that the height of the raised ridges 32 (33) is made larger, assuming variations in the formation of the grooved sash 16 and variations in the construction of the elevating glass 30, and the raised ridges 32 (33) are usually , Are formed so as to protrude vertically with respect to the side walls 20 and 22, so that when the elevating glass 30 is stored in the run body 18, the elevating glass 30
This is because no gap is generated between the sliding lips 24, 26, the ridges 32 (33), and the side walls 20, 22.

In view of the above, the present invention provides a glass run for an automobile that can prevent rattling of the glass without substantially increasing the lifting load of the raising and lowering glass even when there is a variation in the construction of the raising and lowering glass. The purpose is to do.

[0009]

SUMMARY OF THE INVENTION The glass run for an automobile according to the present invention solves the above problems by the following constitution.

A glass run for an automobile mounted on a glass sliding portion such as an automobile door, the run body having a channel cross section fitted and mounted in a grooved sash of the glass sliding portion;
In a configuration including a pair of sliding lips that are curved and protrude from the ends of both side walls of the run body toward the groove bottom, the sliding lip inside the vehicle prevents rattling of the rising and falling glass. The rattle preventing lip has a base portion connected to a substantially central portion of a sliding lip on the inside of the vehicle, and the base portion side is a side wall portion on the vehicle inside when the elevating glass is stored in the run body. , And the tip side is curved and protruded in a direction substantially parallel to or apart from the side wall portion.

[0011]

The glass run for an automobile of the present invention is
In the configuration of the conventional glass run, the sliding lip on the inside of the vehicle is provided with a rattle preventing lip for preventing rattling of the elevating glass, and the rattle preventing lip has its base substantially at the center of the sliding lip inside the vehicle. When the elevating glass is housed in the run main body, the front side is curved and protrudes in a direction substantially parallel to or away from the side wall while the base side faces the side wall on the vehicle interior side. ,
The following operations and effects are achieved (see FIGS. 3 and 4).

When the elevating glass 30 attempts to vibrate,
Due to the presence of the rattling preventing lip 36, the inside sliding lip 24 is prevented from moving in such a way as to generate rattling noise inside the vehicle, and the elevating glass 30 does not generate rattling noise.

On the other hand, in the case where the elevating glass 30 is to be stored in the run main body 18, when the elevating glass 30 is located inside the vehicle due to variation in installation, the original portion of the rattling sound preventing lip 36 is pulled, but the tip side is closed. In the above, a gap is formed between the sliding lip 24 and the tip of the sliding lip 24 inside the vehicle, and the rattle preventing lip 36 is curved and protrudes. For this reason, the rattle preventing lip 36
Easily escapes by the above gap. For this reason, the lifting load of the lifting glass hardly increases.

Therefore, the glass run for an automobile according to the present invention can prevent the rattling of the glass with almost no increase in the lifting load of the raising / lowering glass even if there is a variation in the construction of the raising / lowering glass.
