Description

  The present invention relates to an automobile door weather strip that is attached along the periphery of an automobile door and elastically contacts the door opening edge when the door is closed to seal a gap between the door and the body, and an attachment structure of the automobile door weather strip. Is.

  As shown in FIGS. 8 and 9, a door weather strip 10 is provided on the outside of the vehicle and an opening weather strip 20 is provided on the inside of the vehicle between the door opening edge of the body panel 1 of the automobile and the door D. The inside and outside of the vehicle are sealed (for example, see FIG. 3 of Patent Document 1). FIG. 9 shows a mounting structure for an automotive door weatherstrip according to a conventional example, and corresponds to an enlarged cross-sectional view taken along line AA in the external side view of the automobile shown in FIG.

The door weather strip 10 is attached to the entire periphery along the outer peripheral edge portion of the door D. On the roof side, as shown in FIG. 9, an attachment base portion 11 attached to the outer periphery side of the door sash 3 by a clip 4. And a hollow main seal portion 12 and a lip-shaped sub seal portion 13 which are integrally formed on the vehicle inner side and the vehicle outer side of the mounting base 11 and elastically contact the door opening edge of the body panel 1 when the door D is closed. .
On the other hand, the opening weather strip 20 has an opening trim 21 having a substantially U-shaped cross section that is attached so as to sandwich the flange 2 formed inside the door opening edge vehicle of the body panel 1, and an opening trim 21 on the vehicle outer side surface of the opening trim 21. A hollow seal portion 22 that is integrally formed and elastically contacts the inside of the door sash 3 when the door D is closed is provided.
Further, on the inner peripheral side of the door sash 3, a mounting base 31 having a substantially U-shaped cross section and a vehicle inner lip formed integrally with both ends of the mounting base 31 and in sliding contact with the inside and outside of the door glass 5 that moves up and down. The glass run 30 provided with the part 32 and the vehicle outer side lip part 33 is attached.

Here, the main seal portion 12 of the door weather strip 10 is formed with a hollow portion having a cross-sectional shape close to a circle, and when the door D is closed, the main seal portion 12 is bent at the corner portion P of the body panel 1. It is bent so that it spreads laterally in a direction perpendicular to the direction in which the hollow portion is elastically contacted and performs a sealing function.
For this reason, the entire cross section of the main seal portion 12 becomes large and large, and the door weather strip 10 needs to be positioned and attached at a position where the main seal portion 12 can be elastically contacted with the corner portion P of the body panel 1. Moreover, it is necessary to form the corner | angular part P in the body panel 1 side.

Moreover, since the cross-sectional shape of the main seal part 12 is hollow as described above, the cross-sectional shape of the sub-seal part 13 is a lip shape and is not subject to right and left, so it is used for both the left and right doors. Even if the cross-sectional shape of the door weather strip is the same, it is necessary to manufacture the door weather strip for the right door and the door weather strip for the left door with their processing directions aligned (for example, the positions of the holes for the clips) Such). FIG. 1 of Patent Document 1 describes a hollow cross-sectional shape with respect to both the main seal portion and the sub-seal portion, but it is asymmetrical because it is not the same shape.
For this reason, it is necessary to install the right and left equipment to manufacture the door weather strips used for the left and right doors respectively, and the installation of the door weather strips also requires matching the left and right, which increases the installation time and cost. .

  On the other hand, there is a demand for simplifying the manufacturing process and reducing the cost by making the cross-sectional shape of the door weather strip the same cross-sectional shape over the entire periphery of the door (for example, Patent Document 2). Since it is difficult to make both the main seal portion and the sub seal portion have an extrusion molding cross section, the invention described in Patent Document 2 adopts a method in which the sub seal portion is formed into a molded body.

  In addition, although the door weather strip which has the double hollow cross section of substantially the same shape is known (patent document 3), since both hollow cross sections are contacting each other at the time of elastic contact, the site | part to seal becomes a limited range. In addition, the same cross-sectional shape cannot be made over the entire periphery of the door.

The cross section of the base portion (51) is substantially bilaterally symmetric with respect to a center line (L) that divides the vehicle outer side and the vehicle inner side into ½.

  According to a fourth aspect of the present invention, the first seal portion (52) and the second seal portion (53) have a cross-sectional shape such that the cross-section of the mounting base portion (51) is 1 / It is characterized by being substantially bilaterally symmetric with respect to a center line (L) that is divided into two.

  The invention according to claim 5 is characterized in that a cross-sectional shape of the mounting base (51) is substantially symmetrical with respect to the center line (L).

  According to a sixth aspect of the present invention, in the automobile door weather strip (50) according to any one of the first to fifth aspects, both ends of one extruded product having the same cross-sectional shape are provided. It is characterized by being attached along the entire circumference of the outer peripheral edge of the door of the automobile by molding and connecting.

According to a seventh aspect of the present invention, there is provided a structure in which the automobile door weather strip (50) according to any one of the first to sixth aspects is attached along the entire periphery of the outer peripheral edge of the automobile door. Because
In the portion of the automobile door weather strip (50) attached to the upper side of the door (D) and facing the roof of the automobile, both the first seal portion (52) and the second seal portion (53) are provided. Elastically contact the roof,
In the part of the automobile door weather strip (50) attached to the front vertical side, the rear vertical side, and the lower side of the door (D), only the second seal part (53) located inside the vehicle is used as the door opening edge. It is attached so that it may be elastically contacted to a part (1).

  The invention according to claim 8 is a vehicle roof portion where the inner side surface of the second seal portion (53) of the automotive door weather strip (50) attached to the upper side of the door (D) is elastically contacted. The surface is inclined downward.

  Note that symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and modes for carrying out the invention described later.

According to the invention of the automobile door weather strip according to claim 1 of the present invention, the door outer peripheral edge portion and the door opening edge portion are provided on the vehicle outer side and the vehicle inner side of the mounting base attached along the door outer peripheral edge portion of the automobile. The first seal portion and the second seal portion that seal the gap are integrally formed, and the first seal portion and the second seal portion are formed as seal lips. Compared with the main seal part 12, the cross-sectional area can be reduced to make the whole compact, and deformation such as sink marks or an inclination of the attachment base part to the attachment surface hardly occur at the corner part. .
Further, since the first seal portion and the second seal portion are integrally formed in an inverted C shape from the mounting base so as not to contact each other when elastically contacting the door opening edge, the first seal portion and the second seal portion are formed. The sealing portion can sufficiently exhibit the sealing function possessed individually. Also, it is difficult for sink marks and mounting bases in the corners to be inclined with respect to the mounting surface.
In particular, the second seal portion is bent as the seal lip so that the inner side surface of the vehicle is elastically contacted with the door opening edge and the front end portion is bent toward the outer side of the vehicle, so the door opening edge may be flat as in the conventional example. The corner P does not need to be processed and formed, and the positioning of the door weatherstrip requires less stringency than the conventional example.

  The first seal portion and the second seal portion can be formed as, for example, a seal lip having a tongue-like cross section. However, as in the invention according to claim 2, the first seal portion and the second seal portion are formed into a hollow seal lip and have a tapered cross-sectional shape toward the tip. In particular, a hollow seal lip is excellent in sealing performance.

Further, according to the inventions according to claim 3 and claim 4, the cross-sectional shape of the first seal portion and the second seal portion or the vehicle outer side surface of the cross-sectional shape of the first seal portion and the vehicle inner side surface of the cross-sectional shape of the second seal portion. Therefore, it is possible to use one door weatherstrip for both the right door and the left door even after molding, before molding which requires a mold. Therefore, in order to manufacture door weather strips that correspond to the left and right doors respectively, left and right dedicated equipment (such as a hole punch for a clip and a mold for molding) is not required, and only one piece of equipment is required, thereby reducing costs. In addition, the installation position of the equipment is reduced, so that the space can be saved. Also, the door weather strip can be easily assembled because it is not necessary to match the left and right sides.
It should be noted that, as in the invention according to claim 3, it is not substantially the entire cross-section, such as the vehicle outer side surface of the cross-sectional shape of the first seal portion and the vehicle inner side surface of the cross-sectional shape of the second seal portion, but partially symmetrical This is because many facilities for manufacturing door weather strips are based on the outer surface of the seal portion.
Further, as in the invention according to the fifth aspect, the cross-sectional shape of the mounting base portion can be more easily assembled by making it substantially symmetrical.

  Moreover, according to the invention which concerns on Claim 6, an automobile door weatherstrip is carried out to the perimeter of the outer-periphery edge part of a motor vehicle by carrying out the die-molding connection of the both ends of one extrusion molded product with the same cross-sectional shape. Since it is attached along, it is simple in structure and easy to manufacture. Moreover, if the cross-sectional shape is substantially bilaterally symmetrical and has the same single-turn configuration, the door weather strip will not easily fall after being assembled to the door.

  According to the seventh aspect of the invention of the vehicle door weather strip mounting structure, both the first seal portion and the second seal portion of the vehicle door weather strip are elastically opposed to the opposed roof on the upper side of the door. However, since only the second seal part is elastically contacted with the door opening edge at the front vertical side, rear vertical side, and lower side of the door, it is possible to ensure sufficient sealing performance for the entire periphery of the door. In addition to being able to do so, the door closing performance is not particularly deteriorated.

  According to the invention according to claim 8, the part of the roof of the automobile, which is in contact with the inner side surface of the second seal portion of the door weather strip for automobiles attached to the upper side of the door, is inclined downward. Therefore, the second seal portion is easily bent so that the tip end portion is bent toward the outside of the vehicle at the time of elastic contact, and the sealing performance can be sufficiently exerted.

The first seal portion 52 and the second seal portion 53 that seal the gap between the door opening edge and the body panel 1 that is the door opening edge are formed integrally, and the shapes of the first seal portion 52 and the second seal portion 53 are the same. Since it is a hollow seal lip, the cross-sectional area can be reduced compared to the hollow main seal portion 12 shown in the conventional example (FIG. 9), and the entire corner can be made compact. It is difficult for the deformation or the mounting base 51 to be inclined with respect to the mounting surface.
Further, since the first seal portion 52 and the second seal portion 53 are integrally formed in an inverted C shape from the mounting base portion 51 so as not to contact each other when elastically contacting the body panel 1, the first seal portion 52 is formed. And the 2nd seal | sticker part 53 can fully exhibit the sealing function which it has individually.

In particular, the second seal portion 53 is bent as a seal lip such that the inner side surface 53b of the vehicle is in elastic contact with the body panel 1 and the tip end portion is bent toward the outer side of the vehicle. In addition to the need to process and form the corners P, the positioning of the door weatherstrip 50 also requires less stringency than the prior art.

In addition, since the cross-sectional shapes of the first seal portion 52 and the second seal portion 53 are substantially bilaterally symmetric, of course, before molding which requires a mold, one door weatherstrip 50 is attached to the right door even after molding. D and left door D can be used. Therefore, in order to manufacture the door weather strip 50 corresponding to each of the left and right doors D, there is no need for left and right dedicated equipment (such as a hole punch for a clip or a mold for molding), and only one piece of equipment is required. Therefore, the cost can be reduced and the space can be saved. Further, since the door weather strip 50 does not need to be matched to the left and right, the door weather strip 50 can be easily assembled and the assembling time can be shortened.
Furthermore, in addition to the first seal portion 52 and the second seal portion 53, the cross-sectional shape of the mounting base portion 51 is also substantially bilaterally symmetric, so that assembly can be performed more easily and manufacture is also easy.

  Further, the automobile door weather strip 50 is attached along the entire periphery of the outer peripheral edge of the door of the automobile by molding and connecting both ends of a single extruded product having the same cross-sectional shape. Is easy and easy to manufacture. Further, since the cross-sectional shape is substantially symmetrical and the same one, the door weather strip 50 is unlikely to roll over after being assembled to the door D.

In the embodiment of the present invention, in addition to the first seal portion 52 and the second seal portion 53, the mounting base portion 51, that is, the entire cross-sectional shape of the door weatherstrip 50 is substantially symmetrical with respect to the center line L. Only the first seal portion 52 and the second seal portion 53 are substantially bilaterally symmetric. Further, only the vehicle outer side surface 52a of the cross-sectional shape of the first seal portion 52 and the vehicle inner side surface 53b of the cross-sectional shape of the second seal portion 53 are substantially omitted. It can also be symmetric (that is, the hollow cavity shape can be asymmetrical). Here, “substantially bilaterally symmetric” means that the shape is bilaterally symmetric to the extent that the door weather strip 50 can be assembled to both the right door D and the left door D.
It is a seal part as equipment for manufacturing the door weather strip 50 that the vehicle outer side surface 52a of the first seal part 52 and the vehicle inner side face 53b of the second seal part 53 are partially symmetrical rather than the entire cross section. This is because there are many things that are based on the outer surface.

  Further, the door weather strip 50 is assembled to the door sash 3 with the clip 4 to form the hollow portion for inserting the clip 4 in the mounting base 51. However, as shown in FIG. 6A, the hollow portion is provided. Instead, the attachment base 51X (51) may be assembled to the fitting portion formed by bending the shape of the retainer R attached to the door sash 3 or the door sash 3. Further, as shown in FIG. 6B, if the sealing function is sufficiently ensured, the first seal portion 52X (52) is used instead of the hollow first seal portion 52 and the second seal portion 53. The second seal portion 53X (53) may be a sealing lip having a tongue-like cross section.
