Description

The present invention relates to a fixed window attached to a vehicle door.

Conventionally, vehicle doors include a movable window that can be opened and closed by sliding vertically and a fixed window. A fixed window is a window that is fixed to a door panel in order to close a narrow opening of a door formed on the rear side of a movable window or the like.

As a conventional technique for preventing air, sound, etc. from entering the vehicle through the gap between the fixed window and the door panel, Patent Document 1 describes a weather strip in which the frame of the fixed window abuts the flange of the door panel. A structure with a seal member is disclosed.

In this structure, the weather strip provided on the frame of the fixed window fits between a pair of opposing flanges on the mating surfaces of the inner panel and outer panel that make up the door panel, so that the fixed window and the door panel can be connected to each other. Sealing performance is achieved in the gaps.

Japanese Patent Application Publication No. 2012-11941

In the seal structure between the fixed window and the door panel as described above, there was only one lip of the weather strip that came into contact with each of the pair of flanges of the door panel, but in order to further improve the sound insulation performance, It is conceivable to provide a plurality of lip portions.

However, in the structure described in Patent Document 1, an exterior member such as a garnish is provided behind the fixed window, so there is not enough space and it is not possible to ensure sufficient spacing between the plurality of lip parts. Therefore, when a plurality of lip parts are molded with resin, the cross-sectional area of the mold between the lips becomes small, making it difficult to ensure moldability.

The present invention was made to solve this problem, and an object of the present invention is to provide a fixed window that can ensure the moldability of the plurality of lip portions and improve the sound insulation.

In order to solve the above problems, the fixed window of the present invention is a fixed window that is attached to an opening of a vehicle door, and includes a transparent plate and a frame that holds the periphery of the transparent plate. , the frame has a lower side extending in the longitudinal direction of the vehicle, and a rear side extending upward from a rear end of the lower side and forming a corner together with the lower side, the rear side being , a base portion extending in the vertical direction; and a lip portion protruding inwardly in the vehicle width direction from the base portion and extending in the vertical direction, which corresponds to a first surface facing outward in the vehicle width direction of a door component constituting the vehicle door. a front lip part that can come into contact with the vehicle; a rear lip part that projects from the base toward the rear of the vehicle and extends in the vertical direction and that can come into contact with a second surface of the door component that faces the front of the vehicle; The front lip part and the rear lip part are connected to each other, and the space formed by the front lip part and the rear lip part is vertically connected. a partition wall portion for partitioning, the rear lip portion having an end portion above the corner portion and at a position where it can abut against the second surface, and the partition wall portion having an end portion above the corner portion and abutting the second surface; It is characterized by being located at the position of

According to this configuration, the rear side portion of the frame of the fixed window has two lip portions extending in different directions, that is, the lip portion protrudes inward in the vehicle width direction from the base, and the first surface of the door component member faces outward in the vehicle width direction. and a rear lip portion that protrudes from the base toward the rear of the vehicle and can come into contact with a second surface of the door component facing toward the front of the vehicle. These front lip portions and rear lip portions are different from general multiple lip portions that protrude in the same direction and extend in parallel; they protrude in different directions, so when molding these lip portions with resin, etc. It becomes possible to increase the cross-sectional area of the mold between the lip parts, and it is possible to ensure the moldability of the lip parts. In addition, even if the rear lip part can only maintain contact with the second surface of the door component up to the upper end of the corner part, the partition wall part that partitions the space formed between these lips makes it possible to maintain contact between the lips. It is possible to block sound transmitted through space and improve sound insulation performance. As a result, it is possible to ensure the moldability of the plurality of lip portions and to improve the sound insulation properties.

In the fixed window described above, it is preferable that the thickness of the partition wall portion is thinner than the thickness of each of the front lip portion and the rear lip portion.

According to this configuration, the partition wall portion is formed thinner than the front lip portion and the rear lip portion, so that it is easily deformed. Therefore, it is possible to suppress the reaction force exerted on the frame from the partition wall when the partition wall comes into contact with the door component, and it is possible to suppress displacement when the fixed window is installed. As a result, it is possible to improve the mounting accuracy of the fixed window and to efficiently seal the door components.

In the above fixed window, an upper lip portion that projects inward in the vehicle width direction from the rear side portion above the rear lip portion and extends in the longitudinal direction of the vehicle, a rear end portion of the upper lip portion, and the rear lip portion. and a transition lip portion that connects the upper end portion and extends between the rear lip portion and the upper lip portion such that the direction of the lip tip continuously changes from the rear of the vehicle to the inside in the vehicle width direction. Preferably, the front end portion of the upper lip portion and the upper end portion of the front lip portion are connected.

According to this configuration, the fixed window includes an upper lip portion that projects inward in the vehicle width direction from the rear side portion above the rear lip portion and extends in the longitudinal direction of the vehicle. The rear end of this upper lip extends rearward through a transition lip that extends between the rear lip and the upper lip so that the lip tip direction continuously changes from the rear of the vehicle to the inside in the vehicle width direction. It is connected to the upper end of the lip part. Further, the front end portion of the upper lip portion and the upper end portion of the front lip portion are connected. Therefore, it is possible to maintain high sealing performance by connecting with other lip parts at both the front end and the rear end of the upper lip part. Therefore, it is possible to improve the sealing performance of the upper part of the fixed window, and it is possible to prevent not only air and sound from entering from above the fixed window, but also water such as rainwater from entering, improving sound insulation and It is possible to improve waterproofness.

In the fixed window described above, it is preferable that the partition wall portion has an arcuate outer periphery that can be continuously abutted from the first surface to the second surface.

According to this configuration, the arc-shaped outer periphery of the partition wall portion continuously contacts the door component from the first surface to the second surface, thereby improving sealing performance and, as a result, further improving sound insulation performance. Improvement becomes possible.

According to the fixed window of the present invention, it is possible to ensure the moldability of the plurality of lip portions and to improve the sound insulation properties.
