Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the vehicle door described in Patent Document 1, since the weatherstrip is attached by a double-sided adhesive tape, the weatherstrip is overly restricted and the followability to the vehicle door is poor. In addition, since the entire sash portion is formed by press forming, the cross section cannot be reduced in all parts of the sash portion.

[0006] The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle door capable of ensuring the followability of a weatherstrip and reducing the cross-sectional area of a part of a sash portion.

Means for Solving the Problems

[0007] According to the present invention, a vehicle door for opening and closing an opening of a vehicle body, wherein a weatherstrip that contacts the vehicle body in a state where the opening is closed is provided along an outer edge, comprises a sash portion provided at an upper portion of a door body, the sash portion has a first member extending along a roof side of the vehicle body in the opening, and a second member joined to the first member in the vicinity of a corner portion of an outer edge of the vehicle door and extending along a pillar side of the vehicle body in the opening, the weatherstrip has a first straight section extending along a roof side of the vehicle body in the opening, a second straight section extending along a pillar side of the vehicle body in the opening, and a curved corner section connecting the first straight section and the second straight section, the first member is formed by roll forming, the second member is formed by press forming including the corner portion, the second straight section and the corner section are arranged on the second member, the weatherstrip is attached to the first member and the second member so as to be movable in an extending direction in the first straight section and the second straight section, there is provided a vehicle door in which movement prevention portions for preventing movement of the weatherstrip with respect to the sash portion are respectively provided on the corner section sides of the first straight section and the second straight section.

[0008] According to this vehicle door, since the weatherstrip is attached to the first member and the second member so as to be movable in the extending direction in the first straight section and the second straight section, it is not excessively restricted on the sash section side, and followability with respect to the vehicle door is ensured. Further, since both outer ends of the corner section of the weatherstrip are fixed to the sash section by clips, displacement does not occur in the corner section, and the sealing performance of the corner section is improved. In addition, since the second member in which the corner section of the weatherstrip is disposed is formed by press molding, it has higher rigidity compared to the case of roll forming, and this also improves the sealing performance of the corner section. Further, by making the first member into roll forming, the cross section of the portion constituted by the first member of the sash section can be made smaller. Furthermore, by including the corner section in the second member formed by press molding, the shape of the attachment section of the weatherstrip and the external shape of the sash section can be set independently in the corner section. Thereby, the angle of the corner section of the vehicle door can be freely set, and for example, the angle can be made sharper than before, and the product power of the vehicle can be improved.

[0009] Also, in the above vehicle door, the second straight section may be formed across the second member of the sash section and the inner panel of the door body.

[0010] Also, in the above vehicle door, the vehicle door may be a rear door, and the pillar may be a C pillar.

[0011] Also, in the above vehicle door, the vehicle body may have a quarter panel formed integrally with the outer panel of the C pillar, and the quarter panel may have a convex shape protruding outward in the vehicle width direction.

[0012] The movement preventing portion may include a clip that engages with the weatherstrip and is fixed to the sash section.

Advantages of the Invention

[0013] According to the vehicle door of the present invention, it is possible to ensure the followability of the weather strip and reduce the cross-sectional area of a part of the sash portion.

[0016] As shown in FIG. 1, the automobile vehicle 10 includes a plurality of front doors 30 and rear doors 40 that open and close the front seat opening and the rear seat opening of the vehicle body 20. The vehicle body 20 has an A-pillar 21, a B-pillar (not shown), a C-pillar 22, a roof rail 23, and a side sill 24. The front seat opening is formed by the A-pillar 21, the roof rail 23, the B-pillar, and the side sill 24, and the rear seat opening is formed by the B-pillar, the roof rail 23, the C-pillar 22, and the side sill 24. Further, the vehicle body 20 has a quarter panel 25 that is integrally formed with the C-pillar 22 and forms a design surface, and a convex shape 26 that protrudes outward in the vehicle width direction is formed on the quarter panel 25.

[0017] The vehicle door of the present invention is applied to the rear door 40. The rear door 40 has a door body 41, a sash portion 42 provided at the upper part of the door body 41, and a window glass 43 that opens and closes an opening formed by the door body 41 and the sash portion 42. The window glass 43 moves up and down by a regulator disposed inside the door body 41. In the present embodiment, a convex shape 44 that forms an integrated design with the convex shape 26 of the quarter panel 25 is formed on the outer panel 411 of the door body 41.

[0018] As shown in FIG. 2, the sash portion 42 has a first member 421 extending along the roof side of the vehicle body 20 in the rear seat opening, a second member 422 extending along the C-pillar 22 side of the vehicle body 20 in the rear seat opening, and a third member (not shown) extending along the B-pillar side of the vehicle body 20 in the rear seat opening. The first member 421 and the second member 422 are joined in the vicinity of the corner portion 45 at the upper rear end of the outer edge of the rear door 40, and the first member 421 and the third member are joined at the corner portion 46 at the upper front end. The first member 421 and the third member are formed by roll forming, and the second member 422 is formed by press forming including the corner portion 45.

[0019] As shown in FIG. 2, a weather strip 50 that contacts the vehicle body 20 with the rear seat opening closed is provided along the outer edge of the rear door 40. The weather strip 50 is formed of an elastic material such as rubber. The weather strip 50, in a state of being attached to the rear door 40, has a first straight section 51 extending along the roof side of the vehicle body 20 in the rear seat opening, a second straight section 52 extending along the C-pillar 22 side of the vehicle body 20 in the rear seat opening, and a curved corner section 53 connecting the first straight section 51 and the second straight section 52. As shown in FIG. 2, the second straight section 52 and the corner section 53 are disposed on the second member 422. On the other hand, only the end portion of the first straight section 51 on the corner section 53 side is disposed on the second member 422, and the other portion is disposed on the first member 421. As shown in FIG. 3, clips 60 that prevent the weather strip 50 from moving relative to the rear door 40 are provided on the corner section 53 sides of the first straight section 51 and the second straight section 52, respectively.

[0020] As shown in FIG. 4, on the side opposite to the corner section 53 of the first straight section 51, the weather strip 50 is attached to the first member 421 of the sash section 42. The first member 421 is formed of a single panel by roll forming. In the present embodiment, the first member 421 has a blocking section 421a and a retainer section 421b, and the weather strip 50 is attached to the retainer section 421b. The retainer section 421b has a concave cross-sectional shape with a narrowing opening side and extends in the longitudinal direction of the first member 421. The weather strip 50 fitted into the retainer section 421b is movable in its extending direction and does not hinder the work during attachment.

[0021] As shown in FIG. 5, on the corner section 53 side of the first straight section 51, the weather strip 50 is attached to the attachment surface 422a of the second member 422 of the sash section 42. The attachment surface 422a extends in the extending direction of the weather strip 50 and is continuously formed from the corner section 53 side of the first straight section 51, via the corner section 53, to the corner section 53 side of the second straight section 51. The weather strip 50 is in close contact with the attachment surface 422a from the corner section 53 side of the first straight section 51, via the corner section 53, to the corner section 53 side of the second straight section 51. At a predetermined position on the corner section 53 side of the first straight section 51, the weather strip 50 is fixed to the sash section 42 side by a clip 60 as a movement prevention portion. Specifically, the clip 60 is inserted through a first hole 50a formed in the weather strip 50 and a first hole 422b formed in the attachment surface 422a, and is fixed to the second member 422.

[0022] Also, as shown in FIG. 6, at a predetermined position on the corner section 53 side of the second straight section 52, the weatherstrip 50 is fixed to the sash section 42 side by the clip 60. Specifically, the clip 60 is inserted through the second hole 50b formed in the weatherstrip 50 and the second hole 422c formed in the mounting surface 422a, and is fixed to the second member 422. In the present embodiment, the second member 422 has a blocking section 422d formed by a plurality of panels different from the panel forming the mounting surface 422a, and has a thicker cross section compared to the case of forming by roll forming.

[0023] Also, the second member 422 has a retainer section (not shown) to which the weatherstrip 50 is attached on the side opposite to the corner section 53 of the second straight section 52. This retainer section also has a concave cross-sectional shape with a narrowing opening side, similar to the retainer section 421b of the first member 421, and the weatherstrip 50 fitted into the retainer section is movable in its extending direction. As shown in FIG. 2, in the present embodiment, the second straight section 52 is formed across the second member 422 of the sash section 42 and the inner panel 412 of the door body 40. In the present embodiment, a retainer section into which the weatherstrip 50 is fitted is also formed in the inner panel 412 of the door body 41.

[0024] In the rear door 40 configured as described above, since the weatherstrip 50 is attached to the first member 421 and the second member 422 so as to be movable in the extending direction in the first straight section 51 and the second straight section 52, it is not overly restricted on the sash part 42 side, and followability with respect to the rear door 40 is ensured. Further, since both outer ends of the corner section 53 of the weatherstrip 50 are fixed to the sash part 42 by the clips 60, displacement does not occur in the corner section 53, and the sealing performance of the corner section 53 is improved. In addition to this, since the second member 422 in which the corner section 53 of the weatherstrip 50 is arranged is formed by press working, it has higher rigidity compared to the case of roll working, and also by this the sealing performance of the corner section 53 is improved. As a result, there is no variation in the attachment work of the weatherstrip 50 to the rear door 40, and the weatherstrip 50 does not shift in the corner section 53 due to external input when the rear door 40 is opened and closed, etc., and water intrusion from the outside to the inside of the room can be suppressed.

[0025] Further, the second straight section 52 of the weatherstrip 50 is formed up to the inner panel 412 of the door body 41, and since it does not bend at the boundary between the sash part 42 and the door body 41, the sealing performance of the weatherstrip 50 is also improved by this. By making the second member 422 into press forming, the door body 41 and the sash part 42 can be connected in a smooth shape at the outer edge of the rear end of the rear door 40, and it has a configuration in which it is easy to extend the second straight section 52 up to the inner panel 412.

[0026] Further, by making the first member 421 into roll forming, the cross section of the part of the sash part 42 constituted by the first member 421 can be made small. Furthermore, by including the corner part 45 in the press formed second member 422, the shape of the attachment part of the weatherstrip 50 and the external appearance shape of the sash part 42 can be set independently at the corner part 45. Thereby, the angle of the corner part 45 of the rear door 40 can be set relatively freely, for example, the angle can be made sharper than before, and the product power of the vehicle 10 can be improved.

[0027] In particular, when a convex shape 26 is formed on the quarter panel 25 as in the present embodiment, depending on the shape of the upper rear end side corner of the rear seat opening in the vehicle body 20, it becomes difficult to mold the C-pillar 23 and the quarter panel 25. However, by press-molding the second member 422 of the sash portion 42 of the rear door 40, the shape of the corner portion 45 of the rear door 40 and the upper corner of the rear seat opening can be made into a shape that allows the C-pillar 23 and the quarter panel 25 to be molded.

[0028] In the above embodiment, the present invention is applied to the corner portion 45 at the upper rear end of the rear door 40, but it may also be applied to the corner portion 46 at the upper front end, or the present invention may be applied to the front door 30. Also, in the above embodiment, the clips 60 are provided at two locations, but as long as they are provided on at least the corner section 53 side of the first straight section 51 and the second straight section 52, the clips 60 may be provided at three or more locations. Further, means other than the clips 60 may be used to prevent the weatherstrip 50 from moving relative to the sash portion 42.

[0029] Although the embodiments of the present invention have been described above, the embodiments described above do not limit the invention according to the claims. Also, it should be noted that not all combinations of the features described in the embodiments are essential means for solving the problems of the invention.
