Technical Field
The present disclosure relates to a glass run channel that is mounted on a window frame that is fixedly disposed relative to a door of a vehicle.

Disclosure of Invention
[ problem to be solved by the invention ]
In a state where the glass run is mounted on the window frame, it is necessary to ensure sealing performance by reliably bringing the lip into contact with the window frame. Therefore, in order to prevent the lip from being separated from the window frame due to manufacturing errors of the window frame and the glass run channel, it is preferable to set the error range so that the longest dimension (maximum height) of the side wall of the glass run channel in the pressing direction of the glass run channel is equal to or smaller than the shortest dimension (minimum height) of the side plate of the window frame.
However, when the error range is set as described above, the height of the side plate of the window frame is excessively high with respect to the height of the side wall of the glass run, and there is a possibility that the protruding amount (protruding height) of the front end portion of the side plate of the window frame with respect to the front end portion of the side wall of the glass run is excessively large. When the protruding height of the side plate of the window frame becomes too large, the lip portion is bent from the front end portion of the side plate and rolled up, and a good contact state with the window frame is not obtained, and the sealing performance may be lowered. In addition, rolling up of the lips causes a reduction in the aesthetic appearance.
In addition, in the hollow lip portion of patent document 1, the door-window side region and the window-frame side region facing each other with the hollow portion interposed therebetween are formed of a sponge material softer than the window-frame side region, and therefore, when the protruding amount of the front end portion of the side plate of the window frame with respect to the front end portion of the side wall of the glass run is excessively large, the lip portion is bent and curled up due to deformation of the door-window side region. Therefore, as in the case of the solid lip portion, the sealing performance and the aesthetic property cannot be prevented from being lowered.
Accordingly, an object of the present disclosure is to provide a glass run capable of preventing a reduction in sealing performance or a reduction in appearance beauty by preventing rolling.
[ means for solving the technical problems ]
To achieve the above object, the present disclosure relates to a glass run having: the first and second sash inner surfaces are separated and opposed in the door width direction so as to define fitting recesses that open along a door window opening of a door of the vehicle, and the first and second sash end surfaces extend in a direction of separating from each other from respective front end edge portions of the first and second sash inner surfaces on the door window side; the glass run is an elastic body attached to a window frame fixedly provided with respect to a vehicle door from a door window side, and includes a glass run main body and first and second lips. The glass run main body integrally has a first glass run side wall portion and a second glass run side wall portion which are opposed to and separated from each other, and the first glass run side wall portion and the second glass run side wall portion are fitted into the fitting recess portion of the window frame from the door-window side in a posture of being opposed to the first window frame inner side surface and the second window frame inner side surface, respectively. The first lip portion and the second lip portion extend in directions away from each other from the respective front end edge portions of the first glass run side wall portion and the second glass run side wall portion on the door window side.
In a state where the glass run main body is fitted in the fitting recess, that is, in a state where the glass run is mounted, the first glass run side wall portion and the second glass run side wall portion define a glass entry groove that opens to the door window side to allow entry of the peripheral edge portion of the window glass, and the first lip portion and the second lip portion are opposed to the first window frame end face and the second window frame end face, respectively. At least a first lip of the first lip and the second lip has a hollow shape in which a window frame side lip region opposed to the first window frame end face and a door window side lip region not opposed to the first window frame end face are opposed to each other through a hollow portion. The window frame side lip region is formed in a thin-walled shape thinner than the door window side lip region.
In the above configuration, 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, it is necessary to ensure sealing performance by reliably bringing the first lip portion 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 channel, the error range is preferably set so that the longest dimension (maximum height) of the first glass run channel side wall portion in the pressing direction of the glass run channel is equal to or smaller 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 is excessively high with respect to the height of the first glass run channel side wall portion, and when the first glass run channel side wall portion is the shortest dimension (minimum height) and the first sash inner side surface is the longest dimension (maximum height) in the pressing direction of the glass run channel, the protruding amount (protruding height) of the first sash end surface is the largest with respect to the front end portion (base end portion of the first lip portion) of the glass run channel side wall portion. In this way, there is a possibility that the protruding height of the first sash end face is excessively large, but the first lip portion is a hollow shape in which the sash side lip region opposing the first sash end face and the door side lip region not opposing the first sash end face are opposed to each other through the hollow portion, and since the sash side lip region is formed in a thin wall shape thinner than the door side lip region, even when the protruding height of the first sash end face is excessively large, the sash side lip region flexibly and elastically deforms in a state in which elastic deformation of the door side lip region is suppressed, and the protruding of the first sash end face is well absorbed. Therefore, the first lip portion can be prevented from being bent and rolled from the front end portion of the first glass run side wall portion, which results in a decrease in sealing performance and a decrease in appearance aesthetic quality.
In addition, the sash side lip region in the glass run attached state may be elastically deformed by being pressed by the first sash end face.
In the above configuration, the window frame side lip region in the glass run mounted state is pressed by the first window frame end face to be elastically deformed. That is, even when the first glass run side wall portion has the maximum height within the error range and the first sash inner side surface has the minimum height within the error range, the first lip portion contacts the first sash end surface. Therefore, the first lip portion and the first window frame end face can be sealed more reliably, and the sealing performance can be improved.
[ Effect of the invention ]
According to the present disclosure, by preventing rolling up, a decrease in sealing performance or a decrease in aesthetic appearance can be prevented.

Therefore, in the state where the glass run is mounted, the door inner engagement lip 57a and the door outer engagement lip 57b are reliably in contact with 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 is excessively high with respect to the height of the door inner glass run channel side wall portion 52a, and there is a possibility that the protruding height of the door inner sash end surface 37a becomes excessively high. 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 door sash side lip region 59a, so that the door inner sash side lip region 58a flexibly and elastically deforms in a state in which the elastic deformation of the door inner door sash side lip region 59a is suppressed, and the protruding of the door inner sash end surface 37a can be satisfactorily absorbed.
Therefore, the door inner engagement lip 57a and the door outer engagement lip 57b can be prevented from being bent and curled up from the front end portions of the door inner glass run channel side wall portion 52a and the door outer glass run channel side wall portion 52b, which results in a decrease in sealing performance or a decrease in aesthetic appearance.
The door inner and door outer sash side lip regions 58a, 58b in which the glass run is mounted are pressed by the door inner side sash end surface 37a and the door outer side sash end surface 37b to be elastically deformed. That is, even when the door inner glass run side wall portion 52a and the door outer glass run side wall portion 52b have the maximum height within the error range and the door inner sash inner side surface 36a and the door outer sash inner side surface 36b have the minimum height within the error range, the door inner engagement lip 57a and the door outer engagement lip 57b are in contact with the door inner sash end surface 37a and the door outer sash end surface 37 b. Therefore, the space between the door inner engagement lip 57a and the door outer engagement lip 57b and the door inner sash end surface 37a and the door outer sash end surface 37b can be sealed more reliably, and the sealing performance can be improved.
In the present embodiment, the structure illustrated is as follows: the sash-side lip region 58 and the door-window-side lip region 59 are provided to the door inner engagement lip 57a and the door outer engagement lip 57b, respectively, but the present invention is not limited thereto, and any configuration may be employed as long as the sash-side lip region 58 and the door-window-side lip region 59 are provided to at least one of the door inner engagement lip 57a and the door outer engagement lip 57 b.
In the present embodiment, the structure illustrated is as follows: in the state where the glass run is mounted, the door inner and outer sash side lip regions 58a, 58b provided on the door inner and outer side of the door inner and outer engaging lips 57a, 57b are pressed by the door inner and outer sash end faces 37a, 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 door inner and outer sash side lip regions 58a, 58b provided on the door inner and outer sides of the door inner and outer engagement lips 57a, 57b may be configured not to be pressed and contacted by the door inner and outer sash end faces 37a, 37 b.

That is, it is to be added that other embodiments, examples, application techniques, etc. obtained by those skilled in the art based on this embodiment should be all included in the scope of the present disclosure.
