Description

  The present invention relates to an opening trim weather strip for automobiles that seals between an automobile door and a vehicle body opening periphery.

  Conventionally, the seal between the door of the automobile and the periphery of the opening of the vehicle body includes a door weather strip provided on the outer periphery of the door frame of the door, a glass run attached to an inner peripheral channel of the door frame, and the vehicle body opening. And an opening trim weatherstrip attached to the flange on the periphery of the part.

  As shown in FIGS. 3 and 4, the opening trim weather strip 110 is formed by one extrusion molding and is attached to substantially the entire periphery of the vehicle body opening periphery 6 of the vehicle body. 2 or contact the outer periphery of the door panel and seal. As shown in FIG. 5, a flange 7 is provided at the periphery 6 of the opening of the vehicle body, and an opening trim weather strip 110 is attached to the flange 7. The flange 7 is fixed to the front end of the inner panel 8 and the outer panel 9 by welding. Has been formed.

  As shown in FIG. 5, the opening trim weather strip 110 has a hollow seal portion 130 and a mounting base portion (trim portion) 120 having a substantially U-shaped cross section, and is attached to the flange 7 by the mounting base portion (trim portion) 120. It is done. In order to increase the force for gripping the flange 7, the trim portion 120 has a core material 127 such as a metal insert embedded therein, and is formed from a vehicle outer side wall 121, a vehicle inner side wall 122, and a bottom wall 123. (For example, refer to Patent Documents 1 and 2).

  As shown in FIG. 5, an outer side holding lip 124 and an inner side holding lip 125 are formed on the inner surfaces of the vehicle outer side wall 121 and the vehicle inner side wall 122 so as to grip the flange 7. ing. When the flange 7 is inserted into the trim portion 120, the leading ends of the vehicle outer side holding lip 124 and the vehicle inner side holding lip 125 are bent and pressed against the respective side surfaces of the flange 7 to hold the flange 7. 110 can be installed.

  The hollow seal portion 130 includes a first side seal wall 131 that constitutes a side wall on the base side of the flange 7, a second side seal wall 132 that constitutes a side wall on the distal end side of the flange 7, and the door frame 2. The abutting portion seal wall 133 abuts and the abutting lip 135 extending in the extending direction from the tip of the abutting portion seal wall 133. A contact lip 135 is formed at the tip of the hollow seal portion 130 in order to increase the water stoppage. The contact lip 135 is formed in order to increase the water stoppage of the hollow seal portion 130. When the door is closed, the contact portion seal wall 133 and the contact lip 135 of the hollow seal portion 130 abut against the door frame bulging portion 2a without any gap and seal.

  However, as described above, since the opening trim weather strip 110 is formed by one extrusion molding, when the trim portion 120 is attached to the corner portion of the vehicle body, it is bent and attached along the corner. . When the trim part 120 is bent and attached, the hollow seal part 130 is bent so as to be crushed. That is, as shown by the dotted line B in FIG. 5, the contact lip 135 of the hollow seal portion 130 bends downward. Then, the hollow seal portion 130 is deflected by the second side seal wall bent portion 137 and is displaced in the distal end direction of the flange 7 as a whole.

When the door is closed, the hollow seal portion 130 comes into contact with the door frame bulging portion 2a, and the first side seal wall 131 of the hollow seal portion 130 is located near the center as indicated by the dotted line in FIG. It will bend. In this case, the hollow seal portion 130 cannot be brought into contact with the entire surface of the door frame bulge portion 2a, is displaced in the distal direction of the flange 7, and is brought into contact with only a part, resulting in a decrease in sealing performance. It becomes.
Further, a gap is formed between the abutment lip 135 and the door frame bulging portion 2a, and rain water, car wash water, and the like accumulate in this gap. This accumulated rain water, car wash water, etc. was not preferable because it would fall into the car when the door was opened.

  For this reason, an object of this invention is to provide the opening trim weather strip for motor vehicles which can ensure sealing performance even if it attaches to a corner part.

In order to solve the above-mentioned problem, the present invention of claim 1 is an opening trim weather strip that is attached to a flange formed at the periphery of a vehicle body opening of a vehicle and seals between the vehicle door and the periphery of the vehicle body opening.
The opening trim weather strip is provided with a mounting base portion that is attached to the flange, and a hollow seal portion that is provided integrally with the mounting base portion and that contacts the door frame of the automobile door and seals between the automobile door and the periphery of the vehicle body opening. Have
The hollow seal portion includes a first side seal wall that extends from the mounting base and forms a side wall on the base side of the flange, and a second side that extends from the mounting base and forms a side wall on the tip side of the flange. Side contact wall, contact portion seal wall continuous with the other end of each of first side seal wall and second side seal wall, and contact portion from front end of outer contact portion seal wall Consists of a contact lip extending in the extending direction of the seal wall,
A first side seal wall bent portion and a second side seal wall bent portion are formed on the first side seal wall and the second side seal wall, respectively, and the first side seal wall bent portion is the second side portion. The first side seal wall is formed at an obtuse angle with respect to the extended mounting base, while being formed farther from the mounting base than the seal wall bent portion,
The thickness of the abutment seal wall is an opening trim weather strip characterized by being formed thicker than the first side seal wall and the second side seal wall.

  In the first aspect of the present invention, the opening trim weather strip is provided integrally with the attachment base portion attached to the flange and the attachment base portion, and is in contact with the door frame of the automobile door so that the automobile door and the vehicle body opening peripheral edge are It has a hollow seal part that seals the gap. For this reason, when the attachment base portion is attached to the flange, the seal portion can contact the door frame to seal between the door frame and the periphery of the vehicle body opening.

  The hollow seal portion includes a first side seal wall that extends from the mounting base and forms a side wall on the base side of the flange, and a second side that extends from the mounting base and forms a side wall on the tip side of the flange. A contact seal wall, a contact seal wall that is continuous with the other end of each of the first side seal wall and the second side seal wall and contacts the door frame, and a contact seal wall from the tip of the contact seal wall It comprises a contact lip extending in the extending direction. For this reason, when the door is closed, the first side seal wall and the second side seal wall are bent, and the contact portion seal wall and the contact lip are surely brought into contact with the door frame to contact the contact portion seal wall. It can be sealed over a wide area of the lip and has excellent sealing properties.

  Since the first side seal wall and the second side seal wall are formed with a first side seal wall bent portion and a second side seal wall bent portion, respectively, the first side seal wall bent when the door is closed. The bent portion and the second side seal wall bent portion can be bent to prevent abnormal deformation of the hollow seal portion, and the contact portion seal wall and the contact lip can surely contact the door frame bulge portion.

  Since the first side seal wall bent portion is formed farther from the mounting base than the second side seal wall bent portion, the first side seal wall is formed when the opening trim weather strip is attached to the corner portion. Therefore, when the door is closed, the contact lip can reliably contact the door frame bulge. Furthermore, when the door is closed, the first side seal wall is less bent, the abutment seal wall and the abutment lip can be parallel to the flange, and sealing performance can be ensured.

Since the first side seal wall is formed at an obtuse angle with respect to the extending mounting base, the first side sealing wall is extended so that the upper part extends outward from the mounting base. Therefore, even if the opening trim weather strip is attached to the corner portion and the hollow seal portion is pulled and bent, the first side seal wall can be at an angle close to a right angle with respect to the attachment base portion, and the door is closed. Sometimes, the abutting portion seal wall and the abutting lip can be held against the door frame, and can be surely brought into contact with the door frame bulging portion.

  The wall thickness of the abutment seal wall is thicker than the first side seal wall and the second side seal wall. Therefore, even when the opening trim weather strip is attached to the corner, the door frame swells when the door is closed. Even when it comes into contact with the protruding part, it can come into contact with the door frame bulging part without deformation of the contact part sealing wall, and the sealing performance can be improved.

  According to the present invention of claim 2, the base portion extending from the mounting base portion of the second side seal wall is formed of a solid material, and the other portion of the second side seal wall, the first side seal wall The contact seal wall and the contact lip are an opening trim weather strip formed of a sponge material.

  In the present invention of claim 2, since the base portion extending from the mounting base portion of the second side seal wall is formed of a solid material, the door is closed even when the opening trim weather strip is mounted to the corner portion. Even at times, there is little deformation of the base part of the second side seal wall, and abnormal deformation of the hollow seal part is prevented, so that the contact part seal wall and the contact lip are reliably brought into contact with the door frame bulge part. Can do.

  The present invention of claim 3 is the opening trim weather strip in which the outer surface of the abutting portion seal wall abuts in parallel with the bulging portion of the door frame.

  According to the third aspect of the present invention, the outer surface of the abutting portion seal wall abuts in parallel with the bulging portion of the door frame. Sealability can be improved.

  According to a fourth aspect of the present invention, the outer surface of the contact seal wall and the outer surface of the contact lip form a smooth flat surface, and the flat surface is an opening trim weather strip that contacts the bulge of the door frame in parallel. .

  According to the fourth aspect of the present invention, the outer surface of the contact portion seal wall and the outer surface of the contact lip form a smooth flat surface, and the flat surface is in contact with the bulging portion of the door frame. The outer surface of the door and the outer surface of the contact lip can smoothly contact the bulging part of the door frame without gaps, and the seal can be sealed in the area where the contact part seal wall and the contact lip are combined, improving the sealing performance Can be made.

  The present invention of claim 5 is the opening trim weather strip in which the outer surfaces of the second side seal wall, the contact seal wall and the contact lip are coated with a solid material.

  In this invention of Claim 5, since the outer surface of the 2nd side part seal wall, the contact part seal wall, and the contact lip was coat | covered with the solid material, it is excellent in appearance from the vehicle outer side, and an outer surface is smooth. Therefore, sealing performance can be improved.

The first side seal wall and the second side seal wall are formed with a first side seal wall bent portion and a second side seal wall bent portion, respectively. The contact lip can reliably contact the door frame bulge.
Since the first side seal wall bent portion is formed farther from the mounting base than the second side seal wall bent portion, when attached to the corner portion, the amount of bending of the first side seal wall is small, There is little change in the position of the contact seal wall and the contact lip.

Since the first side seal wall is formed at an obtuse angle with respect to the extended mounting base, the first side seal wall is attached to the corner portion and bent so that the hollow seal portion is crushed. The contact portion sealing wall and the contact lip can be reliably brought into contact with the door frame bulging portion.
Since the thickness of the contact portion seal wall is thicker than that of the first side seal wall and the second side seal wall, the contact portion seal wall can contact the door frame bulge without deformation. It is possible to improve the sealing performance.

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a cross-sectional view of a state in which an opening trim weather strip 10 is attached to a flange 7 in the embodiment of the present invention, and FIG. 2 is a view in which the opening trim weather strip 10 is attached to the flange 7 and the door is closed. It is sectional drawing which shows the relationship between the door frame 2 and the opening trim weather strip 10 in the case of.

As shown in FIG. 3, the vehicle body 1 of the automobile has a door opening, and the door opening is opened and closed by a door that is an opening / closing member. The periphery of the door opening forms a vehicle body opening periphery 6, and a flange 7 (FIG. 1, FIG. 2) with the outer panel 9 and the inner panel 8 constituting the vehicle body 1 welded to the vehicle body opening periphery 6. See). An opening trim weather strip 10 is attached to the flange 7 so as to seal between the vehicle body opening peripheral edge 6 and the door.
In the flange 7, the number of panels to be welded changes from about 2 to about 8 depending on the position of the vehicle body opening peripheral edge 6 of the vehicle body 1.

The opening trim weather strip 10 is linearly formed by extrusion. As shown in FIG. 4, the straight opening trim weather strip 10 is attached to the flange 7 so as to form an annular shape along the shape of the periphery 6 of the vehicle body opening. The mounting is performed sequentially from one end of the opening trim weather strip 10 to the flange 7, and when the mounting is completed, the other end is joined to the one end. This terminal may be formed into an annular shape by being joined by the connecting portion 11.
Alternatively, the ends of the opening trim weather strip 10 may be bonded to each other with an adhesive before being attached to form an annular shape.

As shown in FIGS. 1 and 2, the opening trim weather strip 10 is integrally formed from a trim portion (mounting base portion) 20 having a substantially U-shaped cross section, which is attached to the flange 7, and the trim portion 20. A hollow hollow seal portion 30 is provided in contact with the door frame bulging portion 2a to seal between the door and the vehicle body opening peripheral edge 6.
In the embodiment of the present invention, the hollow seal portion 30 is integrally provided on the outer surface of the outer side wall 21 of the trim portion 20. The trim part 20 will be described later.

  A hollow seal portion 30 is integrally formed on the outer surface of the vehicle outer side wall 21 of the trim portion 20. The hollow seal portion 30 includes a first side seal wall 31, a second side seal wall 32, a contact portion seal wall 33, and a contact lip 35. One end of the first side seal wall 31 extends from the base side outer surface of the flange 7 of the outer side wall 21 of the trim portion 20, and the other end is formed continuously with one end of the contact portion seal wall 33. 7 forms the side wall of the hollow seal portion 30 on the root side.

  The second side seal wall 32 has one end extending from the front end side outer surface of the flange 7 of the outer side wall 21 of the trim part 20, and the other end formed continuously with the other end of the contact part seal wall 33. A side wall of the hollow seal portion 30 on the distal end side of the flange 7 is formed. A hollow is formed by the first side seal wall 31, the second side seal wall 32, and the contact portion seal wall 33. The first side seal wall 31 is formed at an obtuse angle as indicated by X in FIG.

An abutting lip 35 extends from the tip of the abutting portion seal wall 33 toward the root of the flange 7 in the extending direction of the abutting portion sealing wall 33. The tip of the first side seal wall 31 is continuous with the back surface of the boundary portion between the contact portion seal wall 33 and the contact lip 35.
The abutting portion seal wall 33 and the abutting lip 35 are formed in a state where the tip direction of the abutting lip 35 is slightly raised before being attached to the flange 7. The outer surface and the outer surface of the abutting lip form a smooth plane, and the plane abuts in parallel with the bulging portion of the door frame.
The abutment seal wall 33 is formed to be thicker than the first side seal wall 31 and the second side seal wall 32.

A first side seal wall bent portion 36 and a second side seal wall bent portion 37 are formed in the first side seal wall 31 and the second side seal wall 32, respectively.
The first side seal wall bent portion 36 is formed farther from the vehicle outer side wall 21 of the trim portion 20 than the second side seal wall bent portion 37. That is, the first side seal wall bent portion 36 is formed closer to the contact portion seal wall 33 than the second side seal wall bent portion 37.

A base portion extending from the trim portion 20 of the second side seal wall 32 is formed of a solid material. The other part of the second side seal wall 32, the first side seal wall 31, the contact part seal wall 33, and the contact lip 35 are formed of a sponge material.
The outer surfaces of the second side seal wall 32, the contact seal wall 33, and the contact lip 35 are covered with a solid material. For this reason, it looks good from the outside of the vehicle, and since the outer surface is smooth, the sealing performance can be improved.

Next, the configuration of the trim part 20 will be described.
The trim portion 20 includes a vehicle outer side wall 21, a vehicle inner side wall 22, and a bottom wall 23, and is formed in a substantially U-shaped cross section. An insert member 27 is embedded in the trim portion 20 in order to increase the strength for gripping the flange 7. The insert member 27 is formed of a sheet metal or a hard resin, and is formed in a ladder shape, a fish bone shape, a zigzag shape, or the like in order to ensure flexibility when attached to a corner portion. The trim portion 20 is formed of a solid material or a fine foam material.

  A vehicle outer side holding lip 24 and a vehicle inner side holding lip 25 that extend in the longitudinal direction and sandwich the flange 7 are formed on the inner surfaces of the vehicle outer side wall 21 and the vehicle inner side wall 22. For this reason, each front-end | tip of the vehicle outer side holding lip 24 and the vehicle inner side holding lip 25 is contact | abutted to the side surface of the both sides of the flange 7, respectively, and the flange 7 is hold | maintained firmly. For this reason, the trim part 20 does not fall down, and the hollow seal part 30 can contact | abut to the door frame 2 reliably, and can ensure sealing performance.

In the present embodiment, the vehicle outer side holding lip 24 is formed to be three shorter after extrusion molding, and the vehicle inner side holding lip 25 is formed to be one long and projecting in an oblique direction inside a substantially U-shaped cross section. For this reason, the flange 7 is positioned on the inner surface side of the vehicle outer side wall 21 and is stably held by the three vehicle outer side holding lips 24. Furthermore, the flange 7 can be stably held by pressing the flange 7 toward the vehicle outer side wall 21 by the vehicle inner side holding lip 25. In addition, it can reliably follow the unevenness and bending of the flange 7 and abut against the flange 7 to ensure sealing performance.
A cover lip 28 extends from the continuous portion of the vehicle interior side wall 22 and the bottom wall 23 in the vehicle interior direction and covers the tip of the garnish 60.

Next, the case where the opening trim weather strip 10 is attached to the flange 7 and the time when the door is closed will be described.
In FIG. 1, the portion indicated by the solid line A of the opening trim weather strip 10 indicates the state before being attached to the flange 7, and the portion indicated by the broken line B indicates the state when the door is opened after being attached to the flange 7. A portion indicated by a dotted line C indicates a state when the door is closed.
FIG. 2 shows a state where the opening trim weather strip 10 is attached to the flange, a deformed state when the door is closed, and a larger deformed state.

  When the opening trim weather strip 10 is attached to the flange 7, the shape of the hollow seal portion 30 does not change in the state indicated by the solid line A in the portion where the flange 7 is linear. In the straight portion, when the door is closed, the contact seal wall 33 and the contact lip 35 contact the door frame bulge 2a in parallel, but the tip of the contact lip 35 is slightly upward (the door frame bulge 2a direction), it is possible to make contact with the door frame bulging portion 2a without gaps like a line seal. Since the trim portion 20 bends along the corner portion at the flange 7 portion forming the corner portion, the hollow seal portion 30 is deformed as described by the broken line B due to the bent shape of the trim portion 20.

When the opening trim weather strip 10 is attached to the corner portion, the first side seal wall 31 is formed at an obtuse angle with respect to the extended trim portion 20, so that the hollow seal portion 30 is crushed. Even if it bends, the first side seal wall 31 changes from an obtuse angle to an angle close to a right angle with respect to the trim portion 20. Then, the contact portion seal wall 33 and the contact lip 35 can be positioned in parallel to the door frame bulging portion 2a.
Moreover, since the contact part sealing wall 33 and the contact lip 35 can contact | abut reliably, without shifting | deviating with respect to the door frame bulging part 2a, a sealing performance is securable.

  When the door is closed, as shown by a dotted line C in FIG. 1, the first side seal wall 31 and the second side seal wall 32 have a first side seal wall bent portion 36 and a second side seal wall, respectively. Since the bent portion 37 is formed, the first side seal wall bent portion 36 and the second side seal wall bent portion 37 are bent when the door is closed to prevent the hollow seal portion 30 from being deformed abnormally. The contact seal wall 33 and the contact lip 35 can reliably contact the door frame bulge 2a.

  Since the first side seal wall bent portion 36 is formed farther from the trim portion 20 than the second side seal wall bent portion 37, the first trim seal strip bent when the opening trim weather strip 10 is attached to the corner portion. The amount of bending of the side seal wall 31 is small, the change in the positions of the contact seal wall 33 and the contact lip 35 is small, and the contact lip 35 reliably contacts the door frame bulging portion 2a when the door is closed. Can be secured.

  When the door is closed, as shown by a dotted line C in FIG. 1, the contact portion seal wall 33 and the contact lip 35 can be brought into contact with the door frame bulging portion 2a in parallel. If it does so, since a clearance gap will not arise between contact | abutting lip 35 and the door frame bulging part 2a, rain water and car wash water will not accumulate in the meantime.

  As shown in FIG. 2, when the door is closed, the door frame bulging portion 2a of the door frame 2 is surely brought into contact with the contact portion seal wall 33 and the contact lip 35 so that the door frame 2 bulges. The gap between the portion 2a and the flange 7 on the periphery 6 of the vehicle body opening can be sealed with a wide area of the contact seal wall 33 and the contact lip 35, and the sealing performance is excellent. Even if there is a variation in the assembly of the door frame 2, the hollow seal portion 30 can reliably contact the door frame bulge portion 2a. A glass run 40 is attached and sealed between the door frame 2 and the door glass.

  The abutment seal wall 33 is formed to be thicker than the first side seal wall 31 and the second side seal wall 32. For this reason, even when the opening trim weather strip 10 is attached to the corner portion, the door frame bulging portion is not deformed without contacting the contact portion sealing wall 33 when contacting the door frame bulging portion 2a when the door is closed. 2a can be contacted, and the sealing performance can be improved.

  Since the first side seal wall 31, the second side seal wall 32, the contact part seal wall 33 and the contact lip 35 are formed of sponge material, the hollow seal part 30 contacts the door frame 2. Sometimes, it can flexibly abut against the door frame bulging portion 2a to ensure sealing performance. Since the base portion 41 of the second side seal wall 32 is formed of a solid material, the hollow seal portion 30 is crushed even when the weather strip is bent corresponding to the corner portion of the peripheral edge 6 of the vehicle body opening. Deformation can also be prevented.

Next, a method for manufacturing the opening trim weather strip 10 will be described.
The opening trim weather strip 10 is formed by extrusion molding, and the solid rubber constituting the trim portion 20 and the sponge rubber constituting the insert member 27 and the hollow seal portion 30 can be integrally extruded by an extrusion molding machine.
Thereafter, vulcanization is performed by a normal method, and a groove is formed by laser processing in a state where the shape is stable, and then cut into a predetermined length for one piece.

It is sectional drawing of the state which attached the opening trim weather strip which is embodiment of this invention to the flange. It is sectional drawing which attaches the opening trim weather strip which is embodiment of this invention to a flange, and shows the relationship between the door frame at the time of a door closing, and an opening trim weather strip. It is the perspective view seen from back in the state where the door of the car was opened. It is a front view of the door opening trim weather strip which is an embodiment of the invention. It is sectional drawing in the state which attached the conventional door opening trim weather strip to the opening part periphery of a motor vehicle.
