Description

  The present invention relates to a sash portion structure of a vehicle door, and more particularly to a sash portion structure of a separate sash door in which a sash portion is configured separately from a door panel portion.

  The door structure disposed on the side of the vehicle includes a door main body configured by joining a door outer panel and a door inner panel, and a sash that defines a window opening above the door main body. “Sash-integrated doors” formed integrally with each door panel and “sash-separated doors” whose sash portions are formed separately from the door panels.

  The sash-integrated door has a sense of unity from the door body portion to the sash portion and is excellent in appearance, but has a disadvantage that a large die is required for press molding of the door panel, which requires cost. On the other hand, the sash separate door requires a small door panel mold and uses a roll-shaped channel-shaped roll sash for the sash, so it is less expensive than a sash-integrated door. The design restrictions of the sash are large, the parting line is increased above the belt line, and the width of the sash is narrow, so that the weather strip provided around the sash is easily exposed to rainwater.

  Of the doors arranged on the side of the vehicle, the rear door positioned on the rear side in the vehicle front-rear direction needs to move the window glass up and down while avoiding the lock mechanism disposed on the rear side of the door main body. Therefore, conventionally connecting the upper end of the lower sash raised in parallel with the sash on the front side from the inside of the door body, to the upper end or the middle part of the rear sash disposed inclined to the vehicle rear side, A fixed triangular window is provided in the space surrounded by the rear side sash, the lower sash, and the upper edge of the door body, or a cover (garnish) is attached as described in Patent Document 1, and the appearance of this part is adjusted. I am doing so.

  However, in Patent Document 1, the outer cover is located inside the sash, and a parting line is generated at the mating part of the sash and the outer cover. There is a problem that there is no place. In addition, the outer edge of the sash has a weather strip extended to the joint with the outer cover on the outer surface in order to ensure the water tightness of the narrow sash. Therefore, there is a problem that the manufacturing cost increases due to an increase in the size of the mold.

  Weather strips are basically formed by extrusion using rubber materials, but straight extruded products cannot sufficiently follow in areas with large bends such as corners of door sashes. The molding part and the extrusion molding part are connected to ensure the overall sealing performance. The molding part and the extrusion molding part are connected by setting the end part of the extrusion molding part in the mold when molding the molding part. Extrusion molding can form a seal shape with a hollow flexible part at a low cost. Therefore, it is possible to reduce the cost of the weather strip by reducing the range of the molding part where the mold cost is high and using the extrusion part over a wide range. It is preferable for reducing.
