DESCRIPTION OF EMBODIMENTS

Embodiment 1

[0034] FIGS. 1 to 5 show Embodiment 1 of the present disclosure. As shown in FIGS. 1 to 3, an inner weatherstrip 10 is elongated. The inner weatherstrip 10 is located at the lower edge of a window opening 2 of a door 1 of an automobile. The inner weatherstrip 10 elastically comes into contact with a window pane 3 that moves up and down inside the window opening 2. As a result, the inner weatherstrip 10 seals the space between the door panel 5 and the window pane 3 that constitute the door 1. A flange 6 is erected on the upper edge of the door panel 5 by bending an inner door panel 5a. The inner weatherstrip 10 is attached to cover the flange 6 from above.

[0035] FIG. 1 shows an example in which the inner weatherstrip 10 is attached to the front door. The inner weatherstrip 10 can also be attached to the rear door. As a weatherstrip, there is an outer weatherstrip that is located on the vehicle outside of the window pane 3, but the present disclosure relates to the inner weatherstrip 10 located on the vehicle inside. FIGS. 1 and 2 are views of the door 1 viewed from the vehicle inside. FIG. 2 is a perspective view of a state where an inside trim 4 covering the door panel 5 is removed. In FIGS. 2 and 4, reference numeral 50 denotes a sash panel. Reference numeral 51 denotes a run channel holder that extends in the up-down direction along the side surface of the window pane 3. Reference numeral 52 denotes a glass run channel which elastically comes into contact with the side edge of the window pane 3. The glass run channel 52 is attached to the run channel holder 51.

[0036] The inner weatherstrip 10 is basically an extrusion molded article that has a uniform shape along the entire longitudinal direction thereof. The inner weatherstrip 10 has an approximately inverted U-shaped cross section including a vehicle outside sidewall portion 11, a vehicle inside sidewall portion 12, and a top wall portion 13 coupling the upper edges of both of the sidewall portions 11 and 12 to each other. A holding lip 14 is formed continuously along the longitudinal direction on the inner surface of the vehicle inside sidewall portion 12. A shielding lip 15 is formed continuously along the longitudinal direction on the lower surface of the vehicle inside sidewall portion 12. A seal lip 16 is formed continuously along the longitudinal direction on the outer surface of the vehicle outside sidewall portion 11. A decorative lip 17 is formed continuously along the longitudinal direction at a corner portion between the vehicle outside sidewall portion 11 and the top wall portion 13. In Embodiment 1, two holding lips 14 and two seal lips 16 are formed upper and lower. The holding lip 14 and seal lip 16 may be one or three or more. No lip is formed on the inner surface of the vehicle outside sidewall portion 11. The vehicle outside sidewall portion 11 directly comes into contact with the flange 6 (inner door panel 5a).

[0037] In the inner weatherstrip 10, an extrusion molded portion 10p, which will be described later, is made of a material that can be extruded. The vehicle outside sidewall portion 11, the vehicle inside sidewall portion 12, and the top wall portion 13 are made of a material having higher rigidity than each lip. The holding lip 14, the shielding lip 15, the seal lip 16, and the decorative lip 17 are made of a softer material than the vehicle outside sidewall portion 11 and the like.

[0038] Thermoplastic elastomer, thermoplastic resin, rubber, or the like can be used for the material of the vehicle outside sidewall portion 11, the vehicle inside sidewall portion 12, and the top wall portion 13. Specific examples include thermoplastic olefin elastomers (TPO), styrene elastomers (TPS), vinyl chloride resins (PVC), polypropylene resins (PP), and ethylene-propylene-diene copolymers (EPDM). Among them, those having a durometer hardness (type D) of HDA 50 to 80 according to JIS K 7215 are preferable.

[0039] As materials for the holding lip 14, the shielding lip 15, the seal lip 16, and the decorative lip 17, thermoplastic elastomer, thermoplastic resin, rubber, and the like, which are softer and more elastically deformable than the vehicle outside sidewall portion 11 and the like, can be used. Specific examples include thermoplastic olefin elastomers (TPO), styrene elastomers (TPS), vinyl chloride resins (PVC), polypropylene resins (PP), and ethylene-propylene-diene copolymers (EPDM). Among them, those having a durometer hardness (type A) of HDA 50 to 90 according to JIS K 7215 are preferable.

[0040] The inner weatherstrip 10 is attached in a state where the flange 6 of the door panel 5 is inserted between the vehicle outside sidewall portion 11 and the vehicle inside sidewall portion 12. As a result, the inner weatherstrip 10 is located along the upper edge of the door panel 5. In a state where the inner weatherstrip 10 is attached to the door panel 5, the holding lip 14 is in elastic contact with the flange 6 and clamps the flange 6 together with the vehicle outside sidewall portion 11. The shielding lip 15 is in elastic contact with the door panel 5, and the seal lip 16 is in elastic contact with the window panel 3. The decorative lip 17 hides the gap between the inner weatherstrip 10 and the window pane 3.

[0041] As shown in FIGS. 4 and 5, a part of the flange 6 is formed with a protrusion portion 5c. The protrusion portion 5c is formed by making a slit at a part of the inner door panel 5a in the longitudinal direction and cutting and raising the part of the inner door panel 5a toward the vehicle inside. The longitudinal direction of the inner door panel 5a and the flange 6 is the same as the door front-rear direction. The protrusion portion 5c is provided at a part facing the rear end portion of the inner weatherstrip 10. The protrusion portion 5c faces toward the center side in the door front-rear direction. Thereby, the protrusion portion 5c has a contact surface F.sub.1. The contact surface F faces toward the center side in the door front-rear direction, and the surface direction thereof intersects the door front-rear direction.

[0042] In Embodiment 1, the inner door panel 5a is partially reinforced by overlapping a reinforcement 5b. At the rear end portion of the inner weatherstrip 10, the door panel 5 is composed of the inner door panel 5a and the reinforcement 5b.

[0043] The inner weatherstrip 10 is obtained by cutting an extrusion molded article into predetermined lengths. However, as shown in FIGS. 2 and 4, at the rear end portion of the inner weatherstrip 10, the vehicle inside sidewall portion 12 and the holding lip 14 and the shielding lip 15 extending therefrom are cut off by a predetermined size. This cut region is covered with an injection molded portion 10s formed by injection molding. In Embodiment 1, the inner weatherstrip 10 has an injection molded portion 10s at the rear end portion thereof, and the other part is an extrusion molded portion 10p formed by extrusion molding. As a result, the rear end portion shape of the inner weatherstrip 10 can be formed into a shape adapted to the surrounding structure. In Embodiment 1, the rear end portion of the inner weatherstrip 10 corresponds to the one end portion in the longitudinal direction of the present disclosure. The vehicle inside sidewall portion 12 and the like are cut such that the rear end of the extrusion molded portion 10p is aligned with the door front-rear direction position of the contact surface F.sub.1 when the inner weatherstrip 10 is attached to the flange 6.

[0044] The injection molded portion 10s is made of a thermoplastic elastomer such as an olefinic thermoplastic elastomer, and preferably has a durometer hardness (type A) of HDD 50 to 80 according to JIS K 7215. The injection molded portion 10s is integrated with the extrusion molded portion 10p by previously setting a part (rear end portion) of the extrusion molded portion 10p in the cavity of the injection molding die and performing insert molding. As shown in FIGS. 4 and 5, the front end portion of the injection molded portion 10s overlaps the outer surface of the rear end portion of the extrusion molded portion 10p. Specifically, the front end portion of the injection molded portion 10s overlaps the outer surfaces of the vehicle inside sidewall portion 12 and the top wall portion 13 of the extrusion molded portion 10p.

[0045] In the vehicle inside sidewall portion 12, the front side of the injection molded portion 10s comes into contact with the vehicle inside outer surface of the extrusion molded portion 10p, and extends parallel to the extrusion molded portion 10p from the contact part toward the rearward of the rear end surface (positioning surface F.sub.2) of the extrusion molded portion 10p. At a position separated by a predetermined distance rearward from a rear end surface F.sub.2 of the extrusion molded portion 10p, the injection molded portion 10s is located on the vehicle outside and extends parallel to the extrusion molded portion 10p. Further rearward, the injection molded portion 10s is formed in an inclined shape along the door panel 5. In the vehicle inside sidewall portion 12, a step is formed between the vehicle outside side surface of the extrusion molded portion 10p and the vehicle outside side surface of the injection molded portion 10s. As a result, in the vehicle inside sidewall portion 12, a part facing the protrusion portion 5c is recessed toward the vehicle inside, and a positioning surface F.sub.2 extending in a direction intersecting with the longitudinal direction of the inner weatherstrip 10 is formed. The size of the positioning surface F.sub.2 is larger than the contact surface F.sub.1 of the protrusion portion 5c.

[0046] When the inner weatherstrip 10 is attached to the flange 6, the flange 6 is inserted between the vehicle outside sidewall portion 11 and the vehicle inside sidewall portion 12 to cover the flange 6 with the inner weatherstrip 10 from above. At this time, by sliding the inner weatherstrip 10 rearward, the positioning surface F.sub.2 of the inner weatherstrip 10 comes into contact with the contact surface F.sub.1 of the flange 6 (inner door panel 5a). Accordingly, it is possible to easily position the door front-rear direction position of the inner weatherstrip 10.

Embodiment 2

[0047] FIG. 6 shows Embodiment 2 of the present disclosure. The basic configuration of Embodiment 2 is the same as that of Embodiment 1, and the protrusion portion 5c of the flange 6 (inner door panel 5a) protrudes toward the vehicle inside. Further, in the vehicle inside sidewall portion 12, the injection molded portion 10s overlaps the vehicle inside outer surface of the rear end portion of the extrusion molded portion 10p.

[0048] A different point from Embodiment 1 is that a projected piece 12a protrudes toward the vehicle outside from the injection molded portion 10s to cover the rear end surface of the extrusion molded portion 10p. The rear end surface of the projected piece 12a is used as the positioning surface F.sub.2. The positioning surface F.sub.2 is also larger than the contact surface F.sub.1 of the protrusion portion 5c. In FIG. 6, the areas of the positioning surface F.sub.2 and the rear end surface of the extrusion molded portion 10p are the same. The projected piece 12a may be formed such that the positioning surface F.sub.2 is larger than the rear end surface of the extrusion molded portion 10p. Since other parts are the same as those of Embodiment 1, the same members will be given the same reference numerals, and the description thereof will be omitted.

Embodiment 3

[0049] FIGS. 7 and 8 show Embodiment 3 of the present disclosure. In Embodiment 3, the protrusion portion 5c protrudes toward the vehicle outside. The protrusion portion 5c is formed by cutting and raising a part of the reinforcement 5b forming the flange 6. The protrusion portion 5c has the contact surface F.sub.1 that faces toward the center side in the door front-rear direction, and the surface direction thereof intersects the door front-rear direction. Therefore, in a state where the inner weatherstrip 10 is attached, the positioning surface F.sub.2 is formed on the vehicle outside sidewall portion 11 that comes into contact with the reinforcement 5b. The positioning surface F.sub.2 is recessed toward the vehicle outside by a step formed by partially cutting the inner surface of the vehicle outside sidewall portion 11. The positioning surface F.sub.2 intersects the longitudinal direction of the inner weatherstrip 10. In Embodiment 3, it is not necessary to recess a part of the vehicle inside sidewall portion 12 toward the vehicle inside. Therefore, the extrusion molded portion 10p and the injection molded portion 10s are continuous in a flush state. Since other parts are the same as those of Embodiment 1, the same members will be given the same reference numerals, and the description thereof will be omitted.

[0050] Although the representative embodiment of the present disclosure has been described above, the present disclosure is not limited to this, and various modifications are possible without departing from the gist of the present disclosure. For example, the protrusion portion 5c may be provided at the center portion or tip end portion of the inner weatherstrip 10 instead of being provided on the rear side of the inner weatherstrip 10. In these cases as well, the contact surface F.sub.1 is formed to face the center side in the door front-rear direction, and the positioning surface F.sub.2 is formed to face the contact surface F.sub.1.

[0051] In Embodiment 1, as a method for forming the positioning surface F.sub.2 on the vehicle inside sidewall portion 12, the injection molded portion 10s and the extrusion molded portion 10p are connected in a flush state, and then it is also possible to cut a part of the inner side wall portion 12 to make it thinner, or to drill an inner/outer through-hole. In Embodiment 3, as a method for forming the positioning surface F.sub.2 on the vehicle outside sidewall portion 11, an inside/outside through-hole may also be drilled at a part of the vehicle outside sidewall portion 11.

[0052] When the inner door panel 5a is reinforced by the reinforcement 5b, the reinforcement 5b forming the flange 6 is also cut and raised together with the inner door panel 5a, and the reinforcement 5b and the inner door panel 5a can also form the contact surface F.sub.1. When the reinforcement 5b is not located, a part of the inner door panel 5a is cut and raised to form the protrusion portion 5c.

[0053] The size of the positioning surface F.sub.2 does not necessarily have to be larger than the contact surface F.sub.1. It is not always necessary to form the injection molded portion 10s, either.
