Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sealing device for an automobile, and is particularly suitable for a body sand sealing device around a side door.

[Prior Art] An example of a conventional body sand seal device is shown in FIG. 2 (see Japanese Patent Laid-Open No. 58-12823).

In FIG. 1, reference numeral 1 denotes a roof side rail that constitutes an opening peripheral portion of a vehicle body, a closed cross section is formed by an outer panel 1a and an inner panel 1b, joined by upper and lower flanges 1c and 1c, and is vertically installed in a longitudinal direction of the vehicle body. There is. Reference numeral 3 denotes a drip channel in which one side portion 3a is joined to the roof side rail outer panel 1a, and multiple side portions 3b are joined to the roof panel 5, and a drip seal 7 elastically contacted with a door D described later is attached to the multiple side portion 3b. ing. D is a side door as an opening / closing body, and as a whole, the outer panel 9a and the inner panel 9b constitute a door main body 9, and a connecting panel 11 is joined to the door main body 9 and the roof side when the door is closed. A door weather strip 13 elastically contacting the rail outer panel 1a is mounted, and a retainer 15 is attached.
Glass run 1 that makes elastic contact with the lifting door glass 17 via the
9 is attached. Reference numeral 21 is a body side seal fitted to the flange 1c of the roof side rail 1, and is composed of a resin welt 23 made of vinyl chloride or the like and a rubber seal 25 made of sponge rubber or the like and formed in a substantially U shape.

The welts 23 are on both sides 23a, 23 on the inside and outside of the vehicle.
By holding the flange 1c by the lip-shaped holding portions 23c and 23d formed on the inside of the flange 1b,
It is attached to c.

The sealing body 25 is provided so as to project from the side portion 23b of the welt 23 on the vehicle exterior side, and elastically contacts the communication panel 11 of the door D when the door D is closed to seal the interior and exterior of the vehicle. The welt 23 and the seal body 25 are both extrusion-molded, and the seal body 25 is bonded to the welt 23. As the manufacturing method, either the welt 23 and the seal body 25 are extruded at the same time, or the formed seal body 25 is adhered to the formed welt 23. In this example, the coextrusion molding is performed. Is shown. 27 in the figure
Is a door sash mall. Therefore, the vehicle body and the door D are triple-sealed by the drip seal 7, the door weather strip 13, and the body side seal 21.

[Problems to be Solved by the Invention] By the way, in such a body side seal 21, the welt 23 made of a resin such as vinyl chloride can have various color arrangements, and it is possible to match the interior color of the vehicle interior. Although it is possible to apply a color with a good appearance quality, since the rubber seal body 25 such as sponge rubber is required to have sealing properties, weather resistance, ozone resistance, and durability, black synthetic rubber is used. The occupant sees a black object on the other side of the welt 23 that matches the interior color, which impairs the quality of the interior appearance.

In addition, even when the door D is opened, the periphery of the opening of the vehicle body becomes a black color different from the vehicle body color and the interior color, which may impair the appearance quality. Therefore, in order to solve the above-described problem of appearance quality, the appearance of the body side seal 21 from the welt 23 to the seal body 25 is the interior color that is visible.
It may be possible to improve the appearance quality by wrapping it in a cloth that matches the body color.

However, when the body side seal 21 is wrapped with cloth as described above, it is necessary to bond the body side seal 21 and the cloth because the cloth is wrinkled or sagging when simply wrapped, but the welt 23 Generally, the adhesiveness is poor, and the fabric is a bodyside seal 2 after long-term use.
It becomes easy to peel off from No. 1 and it is difficult to secure the appearance quality with good durability.

The present invention has been made in view of the above-mentioned situation, and an object thereof is to provide a sealing device for an automobile having good durability and improved appearance quality.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention attaches a lip-shaped holding portion formed on the inside to the flange by holding the opening peripheral edge flange of the vehicle body. An automotive seal device comprising a substantially U-shaped welt and a seal body projecting on a side portion of the welt on the vehicle exterior side and elastically contacting an opening / closing body, wherein the welt and the seal body are made of a rubber material. In addition to being integrally formed, a U-shaped core metal is embedded in the welt, and the inner bottom region of the welt is made thinner than the regions of the lip-shaped holding portions on both sides of the welt to form a space portion between the flange tip portion. On the other hand, it is an object of the present invention to provide a sealing device for an automobile, which is characterized in that a fabric cover is adhered by an adhesive over the entire outer region of the welt and the seal body.

[Embodiment] In FIG. 1, a body side seal 50 extends from above and below a welt 60 fitted to a flange 1c of a roof side rail 1 as a vehicle body, and a side 62 of the outer side of the welt. A seal body 70 that forms an intermediate portion 72 and elastically contacts a door (see door D in FIG. 2) as an opening / closing body;
The core metal 100 is formed in a substantially U shape and is embedded in the welt 60, and extends from the side portion 64 on the vehicle interior side of these welts 60 to the side portion 62 on the vehicle exterior side of the welt 60 via the seal body 70. It is covered by a fabric cover 80.

The welt 60 and the seal body 70 are integrally formed of rubber such as sponge rubber (eg, ethylene propylene rubber), and are extruded, for example, and the core metal 100 is also embedded by coextrusion. And welt 60
Lip-shaped holding portions 66, 68 for sandwiching the flange 1c from both sides are provided so as to project from the inside of the both side portions 62, 64, and both side portions 6 in the portion where the holding portions 66, 68 are formed.
2, 64 are formed thick and the welt bottom portion 69,
The circumference is formed thin, and a space 65 is formed between the flange 1c and the tip of the flange 1c.

The fabric cover 80 is colored in a color that matches the interior color or the vehicle body color to enhance the appearance of the interior of the vehicle or the appearance quality when the door is opened. Welt 60 through seal body 70
The outer side portion 62 of the vehicle is adhered by an adhesive 90.

The front ends of the side portions 62, 64 of the welt 60 contact the roof side rail 1 via the fabric cover 80, 110, 1.
20.

With this structure, the fabric cover 80 is adhered to the rubber welt 60 and the seal body 72, which have good adhesiveness, so that the adhesive force is stable for a long period of time and is not peeled off from the body side seal 50. It is possible to improve the appearance quality with good durability without causing any occurrence.

Further, the attachment strength of the body side seal 50 to the flange 1c of the vehicle body roof side rail 1 is stably ensured by the welt side portions 62 and 64 which are formed thick, and the core metal 100 further increases the attachment strength. The mounting strength is perfect because it is increased.

Further, although the tip of the flange 1c often causes an opening due to heat at the time of spot welding, it does not come off due to the formation with the space portion 64, and the welt 60 is brought into close contact with the vehicle body roof side rail 1 exactly. 110 and 120, and it looks good.

[Advantages of the Invention] As described above, the present invention has the following advantages.

Since the welt and the seal body are made of rubber, they can be integrally molded and have excellent moldability, and the fabric cover can be reliably bonded by the adhesive. Moreover, the appearance quality is improved.

The strength of the welt reduced by rubber can be reliably reinforced by the core metal.

The space allows the flange to be securely attached to the tip.
