Problems solved by technology

[0010] However, when the hollow sealing lip is molded by extrusion, in order to prevent the hollow part from being crushed by negative pressure during extrusion molding, it is necessary to continuously control the supply of air at a predetermined pressure into the hollow part, thereby molding Work becomes complicated which slows down molding and hurts productivity

[0083] The following is based on Figure 4 with 6 The second embodiment will be described. Figure 6 After installing the glass guide groove 10B on the channel 3 of the door frame 2 figure 1 Sectional view of line A-A. The second embodiment is different from the first embodiment in the contact surface 32 of the inner side wall 30 of the glass run channel 10B and the inner side sealing lip body 61, and the other parts are similar. Therefore, the description of the contact surface 32 and the other parts other than the inside seal lip body 61 are omitted. The contact surface 32 has an inner side wall protrusion 33 near the middle of the inner surface of the inner side wall 30. From the protrusion 33 to the bottom wall 40, an arc-like curved surface is continuously formed in the cross section.

[0084]Therefore, when the door glass 5 is inserted at a predetermined position inside the U-shaped cross-section of the glass guide groove 10B, the front end portion 63 of the inner side seal...

[0090] The following is based on Figure 7 with 9 The third embodiment will be described.

[0091] Figure 7 Shown is a sectional view of the extruded part to be installed on the vertical side of the door frame 2.

[0092] The vehicle interior sealing lip 60 extends from the vicinity of the front end of the vehicle interior side wall 30 to the inside of the U-shaped cross-section of the glass run channel body 11. The inner side cover lip 31 extends to the inner side of the vehicle at the front end of the inner side wall 30 of the vehicle.

[0093] The outer side sealing lip 50 extends from the vicinity of the front end of the outer side wall 20 to the inside of the U-shaped cross-section of the glass run channel body 11. The outer cover lip 21 extends to the outer side of the vehicle at the front end of the outer side wall 20.

[0107] The following is based on Figure 8 with 10 The fourth embodiment of the present invention will be described. Figure 8 For the edge figure 1 A cross-sectional view of the glass run channel 10D along the line A-A. Picture 10 Install the glass guide groove 10D on the rear edge of the channel 3 in the door frame 2 figure 1 A cross-sectional view of the glass guide groove 10D on the line A-A. The fourth embodiment is different from the first embodiment in the shape of the inner side sealing lip 60, and other parts are the same. Therefore, the description of the parts other than the inside seal lip 60 is omitted.

[0108] The vehicle interior sealing lip 60 includes a root 61 of the vehicle interior sealing lip and a front end portion 62 thereof, wherein the root 61 extends from the vehicle interior side wall 30 toward the inside of the U-shaped cross-section of the glass runner body 11, and the front end portion 62 is from the vehicle interior The root 61 of the sealing lip...

Abstract

The present invention provides a glass run channel for a vehicle, wherein the sealing lip can prevent the door glass from shifting or vibrating, precisely fix the door glass, reduce the sliding resistance between the door glass and the sealing lip, and prevent abnormal noise. The length of the inner sealing lip is longer than that of the outer sealing lip, and it includes an inner sealing lip body protruding from the inner side wall, a bent portion bent from the body of the inner sealing lip toward the bottom wall, and a front end portion extending from the bent portion A certain length is extended so that when the door glass contacts the inner sealing lip, the front end of the inner sealing lip contacts the side wall of the inner side. The interior sidewall is treated to reduce sliding resistance on the surface of the interior sidewall in contact with the interior seal lip.

Description

Technical field [0001] The present invention relates to a vehicle glass run, which is installed on the inner periphery of a door frame of a vehicle door to guide the door glass to move up and down, while sealing the gap between the door frame and the door glass. Background technique [0002] Such as figure 1 As shown, a glass guide groove 110 is installed on the inner periphery of the door frame 2 of the vehicle door 1 to guide the door glass 5 to move up and down. The cross-sectional structure of the existing glass guide groove is shown in Figure 2, and Figure 2 shows the figure 1 A cross-sectional view along the line A-A. [0003] It should be noted, figure 1 And 2 shows a glass type (sash type) door, and the glass run channel is also suitable for a press type door. [0004] Such as figure 1 As shown, the conventional glass guide groove 110 is usually installed in the channel 3 of the door frame 2 to guide the door glass 5 to move up and down while sealing the gap between t...
