Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a door sash structure for an automobile, and more particularly to a door sash structure for a so-called press door, which is composed of an outer sash and an inner sub-sash which are integrally press-molded with a door outer panel and a door inner panel. Regarding.

Conventional technology Fig. 4.5 shows the door sash structure of a conventional press door, in which the sash body 1 has an outer sash 2 that is press-molded integrally with the door outer panel 4, and an outer sash 2 that is press-molded integrally with the door inner panel 5. The outer sash 2 and the inner sash 3 are joined together at the outer periphery of the sash. The outer sash 2 has a molding mounting part If and a glass run mounting part 12 formed in multiple stages on the inner peripheral edge, and a flange 9 at the end thereof.
It is formed. The inner sash 3 has a shelf 6 formed on its outer periphery, and a door weather strip 7 that is in close contact with the vehicle body opening edge il (14) is attached to the shelf 6 via a retainer 8. A flange IO is bent and formed at the end.A channel material I3 is joined across the end flange 9.lO, and the channel material I3 forms the sash main body (■) into a closed cross section to ensure the sash rigidity. The glass run 15, which also has the function of sealing and slidingly holding the door glass G, is fitted into the joint between the terminal flange 9 of the outer sash 2 and the channel material 13, and the outer peripheral surface is attached to the glass run attachment part 12. and place the sash molding 16 on this glass run 15.
I between the outer edge of the outer circumferential surface and the molded bent part of the molding H part II
II It is installed by elastic engagement. In addition, at the joint between the end flange IO of the inner sub bush 3 and the channel material 13, a sugar nib 17 that positively depicts the end flange 10 from the inner edge of the inner periphery of the glass run 15 is fitted and fixed. This similar structure is, for example,
This is shown in Japanese Patent No. 628.

Problems to be Solved by the Invention Since the glass run 15 is fitted and held at the joint between the end flange 9 of the outer sash 2 and the channel material 13, the mounting accuracy of the glass run 15 affects the molding accuracy of this joint. If the joint is tilted toward the passenger compartment, not only will a gap be created between the outer peripheral surface of the glass run 15 and the inner peripheral edge of the stub molding 16, but also the glass run 15 will be undulated in a part of the sub-shock corner. Deformation occurs and the appearance and sense of quality are significantly impaired. Similarly, the sub sugar nib 17 also connects to the terminal flange lO of the inner sub bush 3.
The molding accuracy of the joint between the channel material 13 and the channel material 13 is easily affected, and if the joint is tilted toward the passenger compartment, a gap will be created between the glass run I5 and the sub-shu corner, and a part of the sub-shock corner will be wavy. If deformation occurs and the joint portion is tilted toward the outside of the vehicle, the terminal flange IO surface of the garniture bushing ends up floating.

Therefore, the present invention enables glass run without being affected by the forming accuracy of the end flange of the outer sash.

To provide an automobile door sash structure in which a sash molding can be attached with high precision.

Means for Solving the Problem In a structure in which the main body of the satchel is made up of an outer satush and an inner satush, the inner circumferential edge of the outer satush is mountain-folded toward the passenger compartment side to form a molding mounting surface, and a flange is bent and formed at the end thereof. The terminal flange is joined to the terminal flange of the inner periphery of the inner sash to form the sash main body with a closed cross section, and a sash molding having a substantially channel-shaped cross section is fixed to the molding mounting surface,
The sash molding is equipped with a glass run.

Function Since the sash molding is directly fixed to the molding mounting surface of the outer sash, the positional relationship between the sash molding and the outer sash is constant, and since the sash molding itself, which has a generally channel-shaped cross section, is provided with a glass run, the relationship between the sash molding and the glass run is The positional relationship is also constant.

Example Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings and figures.

In FIG. 1, the main body seal consists of an outer sash 2 and an inner sash 3, and these outer sashes 2. The inner sash 3 is wound and joined at the outer periphery of the sash. Inner subdivision: A shelf FJ6 is formed on the outer periphery of L3, and a door weather strip 7 that is in close contact with the vehicle body opening edge I4 is attached to this shelf 6 via a retainer 8. A flange IO is bent and formed at the end.
