Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition sash mounting structure arranged on a rear door of an automobile.

[0002]

2. Description of the Related Art A rear door of an automobile equipped with a door sash on the periphery thereof generally has an area of a door window glass that can be raised and lowered and an area of a fixed partition glass.
Partitioned by partition sash. This partition sash is molded in a substantially linear shape, and while its lower part is fixed inside the door body,
The upper end portion is connected to the upper side portion of the door sash so as to form a substantially T shape. Specifically, as shown in FIGS. 9 and 10, a vertical side portion 102a of a bracket 102 formed by bending a strip-shaped metal plate into an L shape at the upper end portion of a partition sash 101 having a substantially H-shaped cross-sectional shape. Is fixed in advance by spot welding, the horizontal side portion 102b of the bracket 102 is overlapped with the bottom wall portion of the door sash 103 having a substantially U-shaped cross section, and one screw is provided from above, that is, from the outer peripheral side of the door. It is fixed by 104. 1
Reference numeral 05 denotes a partition weatherstrip attached around the partition glass 106, which is fitted in the respective grooves of the door sash 103 and the partition sash 101 (for example, JP-A-11-263).
No. 126).

[0003]

However, in the conventional mounting structure as described above, as shown by the arrow in FIG. 9, when the partition sash 101 is mounted, the partition sash 101 rotates about the screw 104. Therefore, the outer surface 10 of the door sash 103
3a to the outer surface 10 of the partition sash 101
Partition sash 10 with 1a tilted
1 may be fixed, impairing the appearance quality,
There was a problem. At the same time, the worker
Since it is necessary to consider the accurate positioning of the partition sash 101 when tightening 04, workability is poor.

Further, in the conventional mounting structure, as shown in FIG. 10, since the partition glass 106 is biased toward the outside of the vehicle compartment, it is relatively larger inside the door sash 103 than the bracket 102 on the vehicle interior side. A gap 107 is generated. Since the gap 107 can serve as a passage for wind noise and water droplets, it has been necessary to close the gap 107, for example, by filling a sponge-like sealing material in order to improve sound insulation and watertightness.

[0005]

According to a first aspect of the present invention, a vertical side portion of an L-shaped bent bracket is integrally fixed to an upper end portion of a partition sash having a substantially H-shaped cross section. Then, in the partition sash mounting structure of the automobile door in which the horizontal side portion of the bracket is screwed to the upper side portion of the door sash having the glass run fitting groove, the upper end portion of the bracket extends to the vehicle interior side. Formed an extended part, and the tip of this extended part,
It is characterized in that the door sash is fitted in a concave groove on the vehicle interior side of the glass run fitting groove.

As a result, the rotation of the partition sash during screwing is restricted, and the partition sash is accurately positioned with respect to the door sash.

The above extension is preferably formed on the metal bracket itself, but it is also possible to integrate a separate member into the bracket.

According to the second aspect of the present invention, the extension portion is formed integrally with the end cap arranged at the end portion of the partition sash with synthetic resin and is bonded to the metal bracket. The end cap is provided so as to fill the gap on the outside of the passenger compartment between the partition sash and the door sash for improving the appearance quality, and by forming the extension portion integrally with this, The rotation of the partition sash can be regulated without increasing the number of parts.

According to the third aspect of the present invention, the extension portion is formed by extending the horizontal side portion of the bracket toward the vehicle interior side, and the upper end portion of the vertical side portion of the bracket is directed toward the vehicle interior side. The extended seal wall portion is formed integrally with the bracket, and the end edge of the seal wall portion on the vehicle interior side is continuous with the tip portion of the extension portion.

That is, the seal wall portion extends to the tip of the extension portion and is integrated with this. Since the tip portion is generally bent downward from the extension portion, it has a shape in which three surfaces, that is, a horizontal side surface, an extension surface, and a vertical side surface are connected to each other. , The rigidity of the bracket becomes high. Then, the seal wall portion at least partially closes the above-mentioned gap generated inside the door sash. If the seal wall portion is made sufficiently large, it is possible to close the gap almost completely.

According to the invention of claim 4 subordinate to claim 3, the outside of the glass fitting portion located in the glass run fitting groove of the door sash is provided at the corner portion of the partition weather strip attached to the partition sash. A partition wall-shaped projection piece is formed to fill a gap between the side surface and the inner wall surface of the door sash on the vehicle interior side, so that the upper edge of the projection piece and the lower edge of the seal wall portion are butted against each other. It is configured.

According to the present invention, the upper region of the gap is covered by the seal wall portion of the bracket, and the lower region is covered by the protruding piece of the partition weather strip.

Further, in the invention of claim 5, the extension portion is formed by extending the horizontal side portion of the bracket toward the inside of the vehicle compartment, and the door sash of the horizontal side portion including the extension portion is formed. The length (L1) in the longitudinal direction is equal to the opening width (L) of the glass run fitting groove of the door sash.
It is smaller than 2).

Therefore, even if the width of the horizontal side portion (dimension in the direction orthogonal to the longitudinal direction of the door sash) is larger than the opening width (L2) of the grass run fitting groove due to the formation of the extension portion. By inserting the partition sash attached with the bracket into the grass run fitting groove in a posture rotated by 90 ° and then returning the partition sash to the predetermined posture by 90 °, the horizontal side portion is arranged in the grass run fitting groove. It is possible to

As shown in the figure, the door sash 3 is formed by bending a band-shaped metal plate into a predetermined cross-sectional shape by roll forming, and has a glass run fitting groove having a substantially U-shaped cross-section that opens toward the inner peripheral side of the door. 11 has a closed cross-section portion 12 that bulges from the side surface to the inside of the passenger compartment, and a flat molding portion 13 that faces the outside of the passenger compartment is integrally formed on the opposite side surface. There is. A retainer 14 made of another metal plate is fixed to the surface of the bottom wall 11a of the glass run fitting groove 11 on the outer peripheral side of the door by spot welding or the like. In addition, this retainer 14
A door weather strip (not shown) is attached to provide a seal between the vehicle body opening edge. A trim 15 for decoration is attached to the outside of the closed cross section 12.

The glass run fitting groove 11 is constituted by the bottom wall portion 11a and the side wall portions 11b and 11c on both sides of the bottom wall portion 11a, which seals the outer periphery of the door window glass 4. A glass run (not shown) is fitted and mounted. Then, in order to lock the grass run, a locking portion 16 is formed at an intermediate position of the side wall portion 11b on the vehicle interior side so as to project into the grass run fitting groove 11, and thereby the bottom of the side wall portion 11b. Wall 1
The portion near 1a is a groove 17 that is relatively recessed toward the vehicle interior.

On the other hand, the partition sash 6 is shown in FIG.
As shown in FIG. 5, the glass run fitting groove 21 and the partition mounting groove 22 have a substantially H-shaped cross-sectional shape in which they are back-to-back, and are composed of a vehicle interior side wall 23, a vehicle interior side wall 24, and an intermediate wall 25. Has been done. At the upper end of the partition sash 6, the vehicle compartment outer side wall portion 23 is extended longer upward than the vehicle compartment inner side wall portion 24 and the intermediate wall portion 25 so as to have a continuous appearance with the molding portion 13 of the door sash 3. (See Figure 4). A synthetic resin end cap, which will be described later, may be disposed between the two.

In order to attach the partition sash 6 to the door sash 3, an L-shaped bent metal bracket 31 is used. This bracket 31
Has a vertical side portion 32 and a horizontal side portion 33 extending from the upper end thereof, and the lower portion of the vertical side portion 32 is fixed to the intermediate wall portion 25 of the partition sash 6 by spot welding. The bracket 31 is arranged on the partition mounting groove 22 side of the partition sash 6, and the horizontal side portion 33 is also positioned on the partition mounting groove 22 side. A screw hole 37 is formed in the horizontal side portion 33.

It is designed to be fixed by one screw 38.

Here, in this embodiment, the horizontal side portion 33 is provided.
The whole is extended to the vehicle interior side, and thereby an extension portion 34 that reaches the vehicle interior side side wall portion 11b of the grass run fitting groove 11 is configured. The tip of the extension 34 is bent downward by 90 ° to form a locking wall 35 having a height corresponding to the width of the groove 17 of the glass run fitting groove 11 (the vertical interval in the drawing). ing. Further, the bracket 3 has the same height as the locking wall 35.
An upper end portion of the vertical side portion 32 of 1 partially extends toward the vehicle compartment side to form a seal wall portion 36. The seal wall portion 36 is continuous with the locking wall portion 35. That is, the extension portion 34 along the horizontal side portion 33, the locking wall portion 35 orthogonal to the extension portion 34, and the seal wall portion 3 orthogonal to both of them.
3 and 6 are joined together. Therefore, the rigidity of the bracket 31 is improved.

In the mounted state of the partition sash 6, as shown in FIG. 4, the locking wall portion 35 is just fitted in the concave groove 17. This allows the screw 3
The rotation of the partition sash 6 around 8 is reliably prevented, and the partition sash 6 is fixed in a state of being positioned in a predetermined position and direction. As a result, the surface of the molding portion 13 and the surface of the vehicle compartment outer side wall portion 23 do not tilt with respect to each other. Further, the seal wall portion 36, as shown in FIG.
It covers the upper part of the gap that was created inside the vehicle interior.

Further, in this embodiment, a partition weather strip 41 attached to the outer periphery of the partition glass 5 is formed with a partition-shaped projection piece 42, and this projection piece 42 is located below the gap as shown in FIG. It covers the part. The partition weather strip 41 is formed of rubber or synthetic resin in a frame shape, and FIG. 5 shows a corner portion corresponding to the bracket 31.
