Description
Technical Field
The present disclosure relates to a glass run mounted on a window frame fixedly provided with respect to a door of a vehicle.
Background

Disclosure of Invention
[ problems to be solved by the invention ]
In a state where the glass run is mounted on the window frame, the lip needs to be reliably brought into contact with the window frame to ensure sealing performance. Therefore, in order to prevent the lip from being separated from the window frame by manufacturing errors of the window frame and the glass run, it is preferable to set an error range such that the longest dimension (maximum height) of the side wall of the glass run in the pressing direction of the glass run is equal to or less than the shortest dimension (minimum height) of the side plate of the window frame.
However, if the error range is set as described above, the height of the side plate of the sash becomes too high relative to the height of the side wall of the glass run, and the amount of protrusion (protrusion height) of the front end portion of the side plate of the sash relative to the front end portion of the side wall of the glass run may become too large. When the protruding height of the side plate of the window frame becomes too large, the lip portion is bent and rolled up from the front end portion of the side plate, and a good contact state with the window frame is not obtained, and the sealing performance may be lowered. Further, the curling of the lip portion causes a reduction in the aesthetic appearance.
Further, since the hollow lip of patent document 1 is formed of a sponge material softer than the sash-side region in the door-window-side region and the sash-side region opposed to each other with the hollow portion interposed therebetween, when the amount of protrusion of the front end portion of the side plate of the sash from the front end portion of the side wall of the glass run is excessively large, the lip is bent and curled up due to deformation of the door-window-side region. Therefore, as in the case of the solid lip, it is impossible to prevent the deterioration of the sealing performance and the deterioration of the appearance.
Accordingly, an object of the present disclosure is to provide a glass run capable of preventing a reduction in sealing performance and a reduction in aesthetic appearance by preventing the glass run from being rolled up.
[ means for solving the problems ]
To achieve the above object, the present disclosure relates to a glass run having: a first sash inner side surface and a second sash inner side surface that are separated from and opposed to each other in the door width direction so as to define a fitting recess that opens along a door window opening of a door of a vehicle, and a first sash end surface and a second sash end surface that extend in directions away from each other from respective front end edge portions of the first sash inner side surface and the second sash inner side surface on the door window side; the glass run is an elastic body that is attached to a window frame that is fixedly provided with respect to a vehicle door from a vehicle door window side, and includes a glass run main body and first and second lips. The glass run channel main body integrally has a first glass run channel side wall portion and a second glass run channel side wall portion that are opposed to each other and separated from each other, and the first glass run channel side wall portion and the second glass run channel side wall portion are fitted to the fitting recess portion of the sash from the door window side in a posture in which the first sash inner side surface and the second sash inner side surface are opposed to each other. The first lip portion and the second lip portion extend in directions away from each other from respective front end edge portions of the first glass run channel side wall portion and the second glass run channel side wall portion on the door window side.
In a state where the glass run channel main body is fitted in the fitting recess, that is, in a state where the glass run channel is mounted, the first glass run channel side wall portion and the second glass run channel side wall portion define a glass inlet groove that is open toward the door window side and allows the peripheral edge portion of the window glass to enter, and the first lip portion and the second lip portion are opposed to the first sash end surface and the second sash end surface, respectively. At least a first lip of the first and second lips has a hollow shape in which a sash side lip region facing the first sash end face and a door window side lip region not facing the first sash end face oppose each other via a hollow portion. The sash side lip region is formed in a thin-walled shape thinner than the door window side lip region.
In the above-described configuration, in a state where the glass run channel main body is fitted to the fitting recess, that is, the mounting glass run channel, it is necessary to ensure sealing performance by reliably bringing the first lip into contact with the first sash end face. Therefore, in order to prevent the first lip from being separated from the first sash end surface by the manufacturing error of the sash and the glass run and generating a gap, it is preferable to set the error range so that the longest dimension (maximum height) of the first glass run side wall portion in the pressing direction of the glass run is equal to or less than the shortest dimension (minimum height) of the first sash inner side surface.
When the error range is set as described above, there is a possibility that the height of the first sash inner side surface becomes excessively high relative to the height of the first glass run channel side wall portion, and when the first glass run channel side wall portion has the shortest dimension (the smallest height) and the first sash inner side surface has the longest dimension (the largest height) in the pressing direction of the glass run channel, the projecting amount (the projecting height) of the first sash end surface becomes the largest relative to the tip end portion (the base end portion of the first lip portion) of the glass run channel side wall portion. In this way, although there is a possibility that the protruding height of the first sash end face may become excessively large, the first lip portion has a hollow shape in which the sash side lip region facing the first sash end face and the door window side lip region not facing the first sash end face oppose each other via the hollow portion, and the sash side lip region is formed in a thin wall shape thinner than the door window side lip region, so even when the protruding height of the first sash end face becomes excessively large, the sash side lip region flexibly and elastically deforms while suppressing elastic deformation of the door window side lip region, and the protrusion of the first sash end face is favorably absorbed. Therefore, it is possible to prevent the first lip portion from being bent and rolled up from the front end portion of the first glass run channel side wall portion, thereby preventing a reduction in sealing performance and a reduction in appearance.
Further, the sash side lip region in the glass run mounted state may be pressed by the first sash end face to be elastically deformed.
In the above configuration, the sash side lip region in the glass run mounted state is pressed by the first sash end face and elastically deformed. That is, even when the first glass run channel side wall portion has a maximum height within the error range and the first sash inner side surface has a minimum height within the error range, the first lip portion contacts the first sash end surface. Therefore, the first lip and the first sash end surface can be more reliably sealed, and the sealing performance can be improved.
[ Effect of the invention ]
According to the present disclosure, by preventing the rolling-up, it is possible to prevent a reduction in sealing performance or a reduction in aesthetic appearance.

In the glass run 8 configured as described above, the error range of the manufacturing errors of the window frame portion 33 and the glass run 8 is set so that the longest dimension (maximum height) of the door inner side glass run side wall portion 52a and the door outer side glass run side wall portion 52b is equal to or less than the shortest dimension (minimum height) of the door inner side sash inner side surface 36a and the door outer side sash inner side surface 36b in the pressing direction of the glass run 8. Therefore, in the state where the glass run is attached, the door inner engagement lip 57a and the door outer engagement lip 57b reliably contact the door inner sash end surface 37a and the door outer sash end surface 37b, and therefore, the sealing performance can be ensured.
By setting the error range as described above, the height of the door inner sash inner surface 36a becomes excessively high relative to the height of the door inner glass run channel side wall portion 52a, and the protruding height of the door inner sash end surface 37a may become excessively large. Even when the protruding height of the door inner sash end surface 37a is excessively large, the door inner engagement lip 57a is formed in a hollow shape, and the door inner sash side lip region 58a is formed in a thin-walled shape thinner than the door inner sash side lip region 59a, so that the door inner sash side lip region 58a is elastically deformed flexibly in a state where the elastic deformation of the door inner sash side lip region 59a is suppressed, and the protrusion of the door inner sash end surface 37a can be absorbed favorably.
Therefore, it is possible to prevent the door inner side engaging lip portion 57a and the door outer side engaging lip portion 57b from being bent and rolled up from the front end portions of the door inner side glass run channel side wall portion 52a and the door outer side glass run channel side wall portion 52b, which may cause a reduction in sealing performance or a reduction in appearance.
The sash side lip regions 58a, 58b on the door inner side and the door outer side in the glass run mounted state are pressed by the door inner sash end surface 37a and the door outer sash end surface 37b and elastically deformed. That is, even when the door inner glass run channel side wall portion 52a and the door outer glass run channel side wall portion 52b have the maximum height within the error range and the door inner sash inner surface 36a and the door outer sash inner surface 36b have the minimum height within the error range, the door inner engagement lip 57a and the door outer engagement lip 57b come into contact with the door inner sash end surface 37a and the door outer sash end surface 37 b. Therefore, the gaps between the door inside engagement lip 57a and the door outside engagement lip 57b and the door inside sash end surface 37a and the door outside sash end surface 37b can be more reliably sealed, and the sealing performance can be improved.
In the present embodiment, the configuration shown by way of example is: the sash side lip region 58 and the door window side lip region 59 are provided in the door inner engaging lip 57a and the door outer engaging lip 57b, respectively, but the present invention is not limited to this, and any configuration may be used as long as the sash side lip region 58 and the door window side lip region 59 are provided in at least one of the door inner engaging lip 57a and the door outer engaging lip 57 b.
In addition, in the present embodiment, the configuration illustrated is: in the state where the glass run is attached, the sash side lip regions 58a, 58b provided on the door inner side and the door outer side of the door inner side engagement lip 57a and the door outer side engagement lip 57b are pressed by the door inner side sash end surface 37a and the door outer side sash end surface 37b to be elastically deformed, but the present invention is not limited thereto. For example, in a state where the glass run is mounted, the sash side lip regions 58a, 58b provided on the door inner side and the door outer side of the door inner side engagement lip 57a and the door outer side engagement lip 57b may be configured not to be pressed and contacted by the door inner side sash end surface 37a and the door outer side sash end surface 37 b.
While the embodiments of the present disclosure have been described above, the present disclosure is not limited to the descriptions and drawings constituting a part of the disclosure of the embodiments. That is, it is necessary to add other embodiments, examples, application techniques, and the like, which are obtained based on the embodiments by a person skilled in the art, and the like, to the scope of the present disclosure.
