Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a structure around a weather strip for guiding a window glass of a vehicle door and keeping its edge portion airtight.

<Prior Art> Conventionally, a weather strip has been provided that guides the peripheral edge of a door window glass of a vehicle in order to hold and seal the edge of the door window glass. I'm trying to get airtightness. Such a windshield weather strip (hereinafter simply referred to as a weather strip) generally consists of a rubber-based member with a U-shaped cross section that is fitted into a U-shaped groove provided in a door sash.

Such a weather strip usually has a tongue integrally formed along its longitudinal direction as an inner contact part that comes into contact with the inner surface of the upper end of the weather strip when the window glass is fully closed. This system absorbs errors in the position of the upper end of the vehicle interior and exterior, ensuring airtightness and avoiding flapping of the window glass due to wind pressure on the window glass or vehicle body vibration.

However, when the window glass is slightly opened, the upper end of the window glass separates from the tongue piece serving as the inner abutment part, and the upper end of the window glass is not held sufficiently. The windshield hits the weather strip due to the impact when opening and closing the door or other vibrations of the vehicle body, which can cause problems such as a banging sound and the windshield flapping. This tendency is particularly noticeable in a window glass having an upper end that is not straight, such as a front side window of a vehicle, because the holding force of the side edge is weak.

Utility Model Publication No. 56-161826 and Utility Model Publication No. 58-26173
A glass guide as shown in the above publication or a glass guide for guiding a window glass is proposed in Japanese Utility Model Application Publication No. 48-25418, but these guides are not suitable for hard synthetic resin materials, etc. However, the above-mentioned problems cannot be solved.

<Problems to be solved by the invention> In view of these problems of the prior art, the main purpose of the present invention is to position the window glass in a slightly open position, that is, a position slightly separated from the weather strip at the top of the door. To provide a weather strip structure which prevents the knocking sound generated when closing a door even when the door is closed.

<Means for Solving the Problems> According to the present invention, an object of the present invention is to provide a structure around a weather strip for a window glass that can be raised and lowered. an inner abutting portion that abuts the inner surface near the upper end of the glass; and an inner surface of the upper end of the window glass at a position spaced downward in the moving direction of the window glass with respect to the inner abutting portion; a protrusion that protrudes toward the outside of the vehicle so as to be opposed to the inner surface and with a slight gap from the inner surface, the protrusion having a rigidity capable of limiting vibrations of the window glass, and at least This is achieved by providing a weather strip structure characterized in that the tip has a soft surface capable of mitigating the impact upon collision with the window glass.

<Function> In this way, the range in which the window glass flaps is limited, and the window glass also prevents the windshield from softening at the protrusion of the weather strip when the door is closed when the window glass is slightly opened for ventilation, etc. The impact is absorbed by the tip.

<Embodiments> The present invention will now be described in detail with reference to specific embodiments with reference to the accompanying drawings.

FIG. 1 is a side view showing a vehicle to which a weather strip structure according to the present invention is applied, in which a window glass 3 is guided in a groove in a sash 2 provided at the top of a door 1. There is.

As shown in FIG. 2, the sash 2 forming the upper end portion of the door 1 includes an outer panel 4, an inner panel 5, and a weather strip retainer 6. The outer panel 4 is made of a flat plate having a shape that follows the outer contour of the vehicle body. The inner panel 5 is
An upper vertical portion 5a caulked to the upper end of the outer panel 4, an intermediate portion 5b extending laterally from the vertical portion toward the interior of the vehicle, and a lower vertical portion 5c hanging down from the inner end of the intermediate portion. It consists of. The weather strip retainer 6 has a U-shaped cross section that opens downward, and is fixedly connected between the lower ends of the outer panel 4 and the inner panel 5 by spot welding.

A door weather strip 8 is attached to the upper surface of the intermediate portion 5b of the inner panel 5 via a retainer 7 having an upwardly open U-shaped cross section.
A seal is formed between the door 1 and the vehicle body 9. A weather strip 10 is fitted into the U-shaped groove of the weather strip retainer 6 to provide a seal between the upper end of the window glass 3 and the sash 2.

The weather strip 10 is fitted into the U-shaped groove of the weather strip retainer 6, and has a main body portion 11 having a U-shaped cross section to receive the upper end of the window glass 3, and a weather strip at the open end thereof. Tongue pieces 12 and 13 integrally protrude into a U-shaped groove formed inside the main body 11.
and a leg portion 14 that is folded back upward from the base of the tongue piece 13 on the inside of the passenger compartment so as to surround both lower ends of the inner panel 5 and the weather strip retainer 6, which are fixedly connected to each other by spot welding. have As shown in FIG. 2, the joint between the inner panel 5 and the weather strip retainer 6 is the joint between the outer panel 4 and the weather strip retainer 6 in order to increase the rigidity and strength of the sash 2. It extends further downward than the other parts.

The connecting portion between the inner panel 5 and the weather strip retainer 6 at the position of the portion 16 shown in FIG. 1 has a bulge 15a in the middle as shown in FIG. A spacer 15 made of a thin metal plate folded in two is attached locally, and the weather strip 10, especially its legs 14, are connected to the inner panel 5 and the weather strip retainer 6 from above the spacer 15. It is wrapped in the joint part of. Therefore, weather strip 10
The portion 17 as a protrusion is the tongue piece 13 on the inside of the passenger compartment.
It bulges out toward the window glass 3 at a slightly lower position.

Figure 3 shows spacer 1 as seen from the - line in Figure 1.
FIG. 2 is a diagram similar to FIG. 2 showing a portion where 5 is not provided. Here, the distance between the surface of the weather strip 10 and the window glass 3 is m, and the bulging portion 17 of the weather strip 10 in FIG.
If the distance between and the window glass 3 is l, then m>
l≧0.

In such a weather strip structure,
When the tip of the windshield 3 is at position A shown in FIGS. 2 and 3, that is, slightly below the fully closed position and slightly below the tongue piece 13 on the inside of the passenger compartment. position, that is, in the slightly open position, the distance l between the protruding portion 17 of the weather strip 10 in FIG. 2 and the window glass 3 is smaller than the similar distance m in FIG. Since the bulging portion 17 supported by the spacer has enough rigidity to damp the vibration of the window glass 3, the tip of the bulging portion 17 is soft. Moreover, since the stress at the time of impact is concentrated in the same part, the weather strip rubber in the same part absorbs the impact force with high effective compliance, so that the relationship between the windshield 3 and the weather strip 10 is It is possible to prevent the tapping sound between the two.

Furthermore, instead of using the spacer 15 of the above embodiment, a portion similar to the bulging portion 17 thereof may be provided on the weather strip retainer 6, or a local bulging portion may be integrally provided on the weather strip 10. Alternatively, a similar effect can be obtained by adhering another rubber member.

Further, although this embodiment has been described with respect to a vehicle having a door sash, it goes without saying that the present invention can be easily applied to a guide portion of a window glass of a vehicle such as a hard-top vehicle that is not provided with a door sash.

<Effects of the invention> As described above, according to the invention, with the simple structure, there is a gap between the window glass and the weather strip when the window glass is in the slightly open position.
In particular, it is possible to prevent the impact noise that occurs when closing the door, so the effect is extremely large.
