  In this type of door weather strip, the body panel side is sealed by the hollow seal portion and the body side seal lip portion, and the door panel side is sealed by the door side seal lip portion and the base portion, so that the door panel and the body panel are sealed. It is configured to prevent water from entering the car. In particular, in the type that is fixed to the base surface of the door panel using a clip, it is high between the door panel (the base surface) and the base portion in order to reliably prevent water intrusion (under water) on the door panel side. Water-tightness (sealability) is required.

  From this point of view, for example, as disclosed in Patent Document 1 and Patent Document 2 and the like, a thick sponge material is disposed at the base portion, so that the elasticity of the sponge material is improved and an appropriate reaction force is obtained. 2. Description of the Related Art There has been known a configuration that improves the water-stopping property between a door panel and a base portion while ensuring door closing performance (performance or flexibility capable of closing a door with a small force).

  Specifically, as shown in FIG. 11, a conventional door weatherstrip 102 is formed by extrusion molding parts P1 and P2 formed by extrusion molding and connected by molding at a molding part P3. In the portion P1, the body panel side is sealed by the hollow seal portion 121 and the body side seal lip portion 122 in a state where the projections 120a and 120a protruding from the base portion 120 are pressed against the base surface of the door panel, and the door The body panel side is configured to be sealed by a low specific gravity sponge material 127 for water stop disposed at the lower end of the side seal lip portions 123 and 124 and the base portion 120 on the vehicle exterior side.

  Indeed, in the configuration of the conventional door weather strip 102 shown in FIG. 11, since the thick sponge material 127 is disposed in the extrusion molding portion P1, the sponge material 127 contracts over the entire length of the extrusion molding portion P1. By being elastically deformed, the stress (seal pressure) on the door panel side is made uniform to prevent undulation, and an improvement in water stoppage between the door panel and the base portion 120 can be expected.

  However, in the mold forming portion P3, the sponge material 127 cannot be integrally formed at the time of molding. Therefore, an auxiliary material (such as a sponge material or the like) not shown as a separate body between the base portion 120 and the door-side seal lip portion 124. )), Etc., and in such a configuration, the seal line is not continuous at the gradually changing portion of the end portion of the sponge material 127 of the extrusion molding part P1, and is adhered. Further, there is a problem that the water stoppage at the molded part P3 is inferior, for example, water intrusion to the inside of the vehicle may occur along the auxiliary material. Furthermore, in such a conventional configuration, there is also a problem that the workability is inferior because it requires a supplementary work and cost.

  As shown in FIGS. 1 and 2, the door weather strip 2 of this embodiment is configured as a door weather strip that is attached to a door panel 10 of an automobile 1 and seals between the door panel 10 and the body panel 11. . The door weather strip 2 includes extrusion molded parts P1 and P2 formed by extrusion molding and a mold molded part P3 molded by mold molding, and extends along the upper portion of the door panel 10 on the roof side of the automobile 1. The extrusion molding part P1 attached along the vertical part of the door panel 10 on the side of the center pillar extending in the vertical direction and the extrusion molding part P2 attached in the vertical direction are respectively formed and connected to the molding part P3.

  As shown in FIGS. 2 to 4, the extruded portion P <b> 1 of the door weather strip 2 is attached mainly along the upper part of the door panel 10 on the roof side of the automobile 1, and includes a base portion 20, a hollow seal portion 21, The body side seal lip part 22, the door side seal lip parts 23, 24, the base lip part 25, the recessed groove part 26, the first flexible part 27, the second flexible part 29, etc. are integrated by extrusion molding. Molded and configured.

  The base portion 20 is formed so as to have substantially the same thickness at a flush portion, and is attached to the base surface 10 a of the door panel 10 via the clip 12. A projecting portion 20a projecting downward from the bottom surface of the base portion 20 is integrally formed at the lower end portion on the vehicle interior side of the base portion 20, and the door weather strip 2 is attached to the door panel 10 while being attached to the base surface 10a. The protrusion 20a is pressure contacted.

  Hereinafter, the vehicle inner side (left side in FIG. 3) from the axial center of the clip 12 that is a vertical axis with respect to the base surface 10a of the door panel 10 is the vehicle inner side of the door weather strip 2, and the vehicle outer side from the axial center of the clip 12 (right side in FIG. 3). Is called the outside of the door weather strip 2.

  The hollow seal portion 21 is formed as a main seal member having an annular cross section, and is integrally formed with the base portion 20 on the vehicle interior side. The hollow seal portion 21 is elastically contacted with the opening edge 11a of the body panel 11 when the door is closed, so that a continuous seal line is formed on the body panel 11 side. Further, a substantially triangular hollow portion 21a is formed between the base portion 20 and the hollow seal portion 21, and door side seal lip portions 23 and 24, which will be described later, are integrally formed on the vehicle outer side wall 28 of the hollow portion 21a. Yes.

  The body-side seal lip portion 22 is formed as a seal member having a tongue-like cross section, and protrudes outward from the hollow seal portion 21 so as to be integrally formed with the base portion 20. The body side seal lip portion 22 is elastically contacted with the opening end edge 11a of the body panel 11 when the door is closed, and the back surface portion is pressed against the opening end edge 11a and is bent into a substantially U-shaped cross section. A seal line is formed on the side.

  The door-side seal lip portions 23 and 24 are formed as tongue-shaped sealing members in cross section, and extend from the above-described vehicle outer side wall 28 extending from the base portion 20 toward the vehicle outer side in the vertical position, respectively. And is integrally molded. The door-side seal lip portions 23 and 24 are elastically contacted with the outer peripheral projecting edge 10b extending substantially perpendicular to the base surface 10a when the door weatherstrip 2 is attached to the door panel 10 and when the door is closed. A double seal line is formed.

  In the door-side seal lip portions 23 and 24, it is difficult to suitably set the amount of elastic contact (elastic deformation amount) with the door panel 10 (the outer peripheral protruding edge 10b), and considering variations in products and mounting, etc. It is difficult to make the amount of elastic contact constant across the entire seal line. In particular, if the amount of elastic contact with the door panel 10 is too large, the door weather strip 2 is inclined toward the vehicle interior while being attached to the door panel 10, and the water stoppage (sealability) and door closing performance are reduced. Become. In the door weather strip 2 of the present embodiment, the water stopping performance and the like that are insufficient in the door-side seal lip portions 23 and 24 are reinforced by the base lip portion 25.

  The base lip portion 25 is formed as a sealing member having a tongue-like cross section, and is formed in the lower end portion on the vehicle outer side of the base portion 20 in an obliquely downward direction toward the vehicle outer side, and is integrally formed with the base portion 20. The base lip portion 25 is continuous from the lower end portion of the base portion 20 at the root portion 25a, and is formed such that the axis connecting the root portion 25a and the tip portion 25b is inclined and the tip portion 25b faces the vehicle exterior side. The base lip portion 25 is elastically brought into contact with the base surface 10a when the door weather strip 2 is attached to the door panel 10 and when the door is closed, and a seal line is formed on the door panel 10 side.

  The concave groove portion 26 is formed in a substantially V-shaped cross section at a parting portion that is a portion between the vehicle outer side wall 28 and the base lip portion 25, and is opened toward the vehicle outer side. Since the front end 25b of the base lip 25 is separated from the vehicle outer side wall 28 by the concave groove 26, the base lip 25 can be elastically contacted with the base surface 10a with the front end 25b tilted toward the vehicle outer side. It is said that.

  The first flexible portion 27 is formed of an elastic material having a specific gravity lower than that of other portions (for example, a highly foamed sponge material (EPDM) or the like), and a base portion of the base lip portion 25 so as to close the concave groove portion 26. It fills from 25a to the front end portion 25b, and is arranged so as not to protrude outward from the front end portion 25b of the base lip portion 25. By disposing the first flexible portion 27 in this manner, the distal end portion 25b of the base lip portion 25 is securely pressed against the base surface 10a when the door weather strip 2 is attached to the door panel 10 and when the door is closed. Can be made.

  The second flexible portion 29 is formed of an elastic material having a specific gravity lower than that of other portions (for example, a highly foamed sponge material (EPDM) or the like) like the first flexible portion 27 described above, and the door side seal lip. It extends toward the vehicle outer side between the portion 24 and the base lip portion 25. The second flexible portion 29 is elastically contacted with the base surface 10a when the door weather strip 2 is attached to the door panel 10 and when the door is closed, so that a seal line is formed on the door panel 10 side.

  The material of the first flexible part 27 and the second flexible part 29 is preferably formed from a highly foamed sponge material (EPDM or the like) having a specific gravity of 0.15 to 0.4. In general, the other portions including the base lip portion 25 are formed of a sponge material or a solid material having a specific gravity greater than 0.4, and therefore, the first flexible portion 27 and the second flexible portion 29 are the other portions. A material having a low specific gravity (0.15 to 0.4) and a high foaming rate is preferably used. This is because when the first flexible portion 27 and the second flexible portion 29 are formed of a material having a specific gravity greater than 0.4, door closing performance is mainly deteriorated.

  The door weather strip 2 of the present embodiment is provided with the first flexible portion 27 and the second flexible portion 29 that are formed of an elastic material having a specific gravity lower than that of other portions in the extruded portion P1. Between the door panel 10 and the base portion 20, the door-side seal lip portions 23 and 24 and the base lip portion 25 are uniformly and stably applied with stress (seal pressure) to prevent water from entering the vehicle (through water). It is comprised so that the water-stopping property can be improved. In particular, by providing the first flexible portion 27, it is possible to absorb an excessive reaction force of the base lip portion 25 elastically contacted with the base surface 10a, and to ensure a good door closing property, It is possible to cause the lip portion 25 to exhibit an appropriate elastic force for maintaining the water stoppage with the door panel 10. Moreover, the amount of elastic contact (elastic deformation amount) of the base lip portion 25 can be increased to prevent undulation in the state in which the door weather strip 2 is attached to the door panel 10 and to improve the reliability of waterstop. .

  As shown in FIGS. 2 and 5, the extrusion part P2 of the door weather strip 2 is attached mainly along the vertical part of the door panel 10 on the center pillar side of the automobile 1, and is similar to the above-described extrusion part P1. The base portion 20, the hollow seal portion 21, the door side seal lip portion 24, the base lip portion 25, and the like are integrally formed by extrusion molding. Unlike the extrusion molding portion P1, the body side seal lip is formed. The part 22, the door-side seal lip part 23, the recessed groove part 26, the first flexible part 27, the second flexible part 29, and the like are not particularly provided.

  As shown in FIGS. 2 and 6 to 10, the molded part P3 of the door weatherstrip 2 is mounted mainly along the corner part of the door panel 10 of the automobile 1, and is similar to the extruded part P1 described above. The part 20, the hollow seal part 21, the body side seal lip part 22, the door side seal lip parts 23, 24, the base lip part 25, the concave groove part 26 and the like are integrally formed by molding. However, unlike the extrusion molding part P1, the first flexible part 27 and the second flexible part 29 are not particularly provided, and a reinforcing rib part 30 is provided instead.

  In the molding part P3, the body side seal lip part 22, the door side seal lip parts 23 and 24, and the base lip part 25 are formed at the end part on the extrusion molding part P1 side, and the body side seal of the corresponding extrusion molding part P1 is formed. A seal line is formed continuously with the lip portion 22, the door-side seal lip portions 23 and 24, and the base lip portion 25 (see FIGS. 2, 4, and 7). On the other hand, the body side seal lip part 22 and the door side seal lip part 23 are not formed at the end on the extrusion molding part P2 side, and the seal line is interrupted, but the door side seal lip part 24 and the base lip part 25 Is formed continuously and is continuous with the door-side seal lip portion 24 and the base lip portion 25 of the corresponding extrusion-molded portion P2, so that the door weather strip 2 (the extrusion-molded portions P1 and P2 and the mold-molded portion P3) is formed. ), A seal line is formed at the door-side seal lip portion 24 and the base lip portion 25 (see FIGS. 2, 5, and 8).

  In the mold forming portion P3, a fin piece 31 is formed on the outer side wall 28 of the hollow portion 21a so as to extend in the outer peripheral direction, and is attached to the door panel 10 via a clip (not shown) (FIGS. 2 and 8). And FIG. 9).

  The reinforcing rib portion 30 is formed in an upright wall shape having a mountain-shaped cross section or a trapezoidal cross section, and both ends are connected to the carved side portion of the vehicle outer side wall 28 so as to connect the vehicle outer side wall 28 and the base lip portion 25 to the groove 26 described above. And the side surface of the base lip portion 25 on the parting portion side are continuously provided. The reinforcing rib portions 30 of the present embodiment are plural (this embodiment) so as to have a predetermined interval (1.5 mm to 5.0 mm) along the concave groove portion 26 at the curved portion of the mold forming portion P3 and to be substantially equidistant. In the example, 13 pieces are arranged, and are erected so that each top ridge line intersects with the direction along the longitudinal direction of the groove 26. When the door weather strip 2 is attached to the door panel 10 and the reinforcing rib portion 30 is bent (elastically deformed) when the door is closed, an elastic force is applied to the base lip portion 25 and the base surface 10a is elastically contacted. The excess reaction force of the base lip portion 25 is absorbed.

  In addition, the reinforcing rib portion 30 extends from the root portion 25a to the tip portion 25b with respect to the base lip portion 25, and does not reach the tip portion 25b from the root portion 25a toward the vehicle outer side from the tip portion 25b. It does not protrude. By forming the reinforcing rib portion 30 in this way, it is possible to ensure the amount of elastic contact (elastic deformation amount) of the base lip portion 25 (the tip end portion 25b), and the door weather strip 2 is attached to the door panel 10. When the door is closed and the door is closed, the tip 25b can be reliably brought into pressure contact with the base surface 10a.

  The reinforcing rib portion 30 is preferably formed so as to give the base lip portion 25 the same stress (seal pressure) as the base lip portion 25 of the extrusion molding portion P1. That is, when the elastic force applied by the reinforcing rib portion 30 is low (reaction force absorption is high), the stress S3 (see FIG. 7) of the base lip portion 25 of the mold forming portion P3 is weakened, and is caused by the base lip portion 25 and the like. Even if the uniformity of the stress (seal pressure) in the seal line is impaired and water can be stopped at the base lip portion 25 in the extrusion molding portion P1, the water stoppage at the base lip portion 25 in the mold forming portion P3. This is because there is a case where it cannot be secured. On the other hand, if the elastic force applied by the reinforcing rib portion 30 is high (reaction force absorption is low), the stress S3 of the base lip portion 25 of the mold forming portion P3 increases, but the door-side seal lip portions 23 and 24 Stress S1 and S2 (see FIG. 7) are weakened and susceptible to variations in product and mounting, etc. As a result, the uniformity of the seal line stress (seal pressure) due to the base lip portion 25 and the like is impaired and sufficient In some cases, it is not possible to guarantee a good water-stopping property.

  As described above, the door weather strip 2 according to the present embodiment includes the base portion 20 attached to the base surface 10a of the door panel 10, the hollow seal portion 21 and the seal lip portion 22 that seals between the door panel 10 and the body panel 11. 23, 24 (body-side seal lip portion 22 and door-side seal lip portions 23, 24), the door weatherstrip 2 is inclined downward toward the vehicle outer side at the lower end portion of the base portion 20 on the vehicle outer side. A base lip portion 25 extending in the direction and elastically contacting the base surface 10 a of the door panel 10, and a portion between the vehicle outer side wall 28 and the base lip portion 25 where the door side seal lip portions 23 and 24 are formed. A recessed groove portion 26 formed in the parting portion, and a reinforcing rib portion 30 formed so as to connect the vehicle outer side wall 28 and the base lip portion 25 to the recessed groove portion 26. Since formed by Bei, form a continuous sealing line to the door panel side enhance water-stopping while ensuring resistance closed door, and can be improved processability.

  That is, the door weather strip 2 of the present embodiment is configured such that the base lip portion 25 is elastically contacted with the base surface 10a when the door weather strip 2 is attached to the door panel 10 and when the door is closed. A continuous seal line can be formed on the door panel 10 side over the entire length of the extrusion molding parts P1 and P2 and the mold molding part P3). The water stoppage between the door panel 10 and the base portion 20 can be increased.

  Further, the reinforcing rib portion 30 is formed so as to connect the vehicle outer side wall 28 and the base lip portion 25 to the recessed groove portion 26 formed in the parting portion between the vehicle outer side wall 28 and the base lip portion 25. Thus, when the door is closed, the reinforcing rib portion 30 bends (elastically deforms), so that an excessive reaction force of the base lip portion 25 elastically contacted with the base surface 10a is absorbed to ensure good door closing performance. In addition, it is possible to exert an elastic force for maintaining the water-stopping property with the door panel 10 with respect to the base lip portion 25, and the stress (seal pressure) in the above-described seal line can be made uniform. Further, in the mold forming portion P3, as compared with the conventional configuration in which a separate auxiliary material (such as a highly foamed sponge material) is attached, the work of attaching the auxiliary material and the cost are unnecessary, and the workability can be improved.

  In particular, in the door weather strip 2 of the present embodiment, the reinforcing rib portion 30 is formed in a standing wall shape and is erected so that the top ridge line intersects the direction along the longitudinal direction of the concave groove portion 26. The elastic force imparted to the lip portion 25 by the bending (elastic deformation) of the reinforcing rib portion 30 can be increased, and the reliability of water stoppage by the base lip portion 25 can be improved.

  Further, since a plurality of reinforcing rib portions 30 are formed along the concave groove portion 26 with a predetermined interval, the base lip portion 25 elastically contacts the door panel 10 by changing the shape and arrangement of the reinforcing rib portions 30. It is possible to finely adjust the stress (seal pressure) generated during the process, and the uniformity of the stress (seal pressure) of the seal line by the base lip portion 25 can be improved.

  In addition, as a structure of the door weather strip 2, it is not limited to the Example mentioned above, A various change is possible unless it deviates from the objective of this invention.

  That is, in the door weather strip 2 of the above-described embodiment, the reinforcing rib portion 30 is formed in a standing wall shape, or a plurality (13 pieces) is arranged along the concave groove portion 26 with a predetermined interval. However, the shape and arrangement of the reinforcing rib portion 30 are not limited to this. For example, the reinforcing rib portion 30 may be formed in a block shape or the like, or may be configured with a smaller number than the number (13) of the present embodiment. In addition, the shape and arrangement having elasticity and reaction force absorbing force are applied as appropriate so that the base lip portion 25 can be given elastic force and can absorb excessive reaction force of the base lip portion 25 elastically contacted with the base surface 10a. can do.

  Further, in the door weather strip 2 of the above-described embodiment, the configuration in which the reinforcing rib portion 30 is continuously integrated with the side surface on the parting portion side of the vehicle outer side wall 28 and the side surface on the parting portion side of the base lip portion 25 has been described. However, the configuration of the reinforcing rib portion 30 is not limited to this, and may be formed so as to connect the vehicle outer side wall 28 and the base lip portion 25. For example, in the recessed groove portion 26, the part of the vehicle outer side wall 29 is on the parting portion side. Is formed only on the side surface of the base lip portion 25 or on the parting portion side of the base lip portion 25 so that the door weatherstrip 2 is attached to the door panel 10 and is in contact with the other side surface when the door is closed.
