Problems solved by technology

[0007] However, according to the glass run channel described in US Pat. No. 5,396,733, during the bonding process of the two constituents, when the two constituents are bonded, the movement of the two constituents in the length direction and the width direction is not restricted, Therefore, it is difficult to precisely join the two constituent members over their entire area, and due to this, there is a fear that the sealing performance may be lowered or the mounting state with the mounting portion may be deteriorated.

[0048] The first embodiment will be described below with reference to the drawings. FIG. 1 is a schematic front view of a vehicle door structure. Fig. 2 is a partial axonometric view of the upper side of the glass run. Figure 3 is an exploded isometric view of the glass run.

[0049] As shown in FIG. 1 , a vehicle door 51 (the front door in the drawing) includes a glass run 1, which is used to guide the lift of the door glass DG, and when the door glass DG is raised to close the window, The gap between the outer periphery of the glass DG and the door frame 52 provides a seal. More specifically, the glass run channel 1 includes an upper side portion 2, a front vertical side portion 3 and a rear vertical side portion 4, the upper side portion 2 constituting a portion corresponding to the upper edge portion of the door glass DG, and the front vertical side portion 3 constitutes a portion extending downward from the front end portion of the upper side portion 2 and corresponds ...

[0088] A second embodiment will be described below with reference to the drawings. Fig. 10 is a sectional view showing the upper side of the glass run. Fig. 11 is a sectional view showing the rear vertical side of the glass run in an exploded state. Figure 12 is an exploded isometric view of the glass run.

[0089] According to the second embodiment, as shown in FIG. 10 , the upper side portion 2 includes a main body portion 111 and a vehicle exterior seal lip 112 and a vehicle interior seal lip 113 . The main body portion 111 includes a bottom 114 fitted to the channel portion DC and an exterior side wall portion 115 and an interior side wall portion 116 extending from the bottom portion 114, and constitutes a substantially U-shaped cross section as a whole. The exterior seal lip 112 extends approximately from the distal end of the exterior wall portion 115 toward the inner periphery of the body portion 111 , and the interior lip seal 113 extends approximately from the dist...

[0122] A third embodiment will be described below with reference to the drawings. Fig. 20 is a sectional view showing a state in which a glass run is attached to a window frame portion. Fig. 21 is a cross-sectional view of the glass run channel in an exploded state.

[0123] As shown in FIG. 20 and FIG. 21 , the upper side part 2 includes: a main body part 211 , a seal lip 212 on the outside of the vehicle, and a seal lip 213 on the inside of the vehicle. The main body portion 211 includes a bottom portion 214 fitted to the channel portion DC, and an outer side wall portion 215 and an inner side wall portion 216 extending from the bottom portion 214 so as to constitute a substantially U-shaped cross section as a whole. The exterior seal lip 212 extends toward the inner peripheral side of the body portion 211 from the tip of the exterior wall portion 215 , and the interior lip seal 213 extends toward the inner periphery of the body portion 211 from the tip of the interior wall...

Abstract

A glass run includes a main body portion and a pair of seal lips. Further, the glass run is constituted by a vehicle exterior side molded member and a vehicle interior side molded member divided at abottom portion of the main body portion. Further, the vehicle exterior side molded member and the vehicle interior side molded member include engaging portions for engaging to be integrated with eachother. By integrating the vehicle exterior side molded member and the vehicle interior side molded member by the engaging portions, the vehicle exterior side molded member is restricted from being shifted to move relative to the vehicle interior side molded member in a vehicle width direction and in a longitudinal direction of the vehicle interior side molded member.

Description

technical field [0001] The invention relates to a glass runway. Background technique [0002] Typically, glass run channels are provided along the inner circumference of the vehicle door frame. Viewed from the cross-sectional direction of the glass run channel, the glass run channel includes a main body portion with a U-shaped cross section, and is provided with an inner sealing lip and an outer sealing lip extending toward the inner side of the main body portion, the main body portion includes a bottom and extends from the bottom The inner side wall part and the outer side wall part of the car. With this glass run, the main body portion is mounted to the mounting portion (runner portion) provided along the inner periphery of the door frame, and the peripheral portion of the inner and outer surfaces of the door glass is sandwiched and sealed by two seal lips. [0003] In addition, the glass run channel is composed of extruded parts and molded parts, the extruded parts are ...
