Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a vehicle door sealing structure for sealing between an automobile body and a door.

[Prior Art] A description will be given with reference to FIG.

6a is a body outer panel, 6b and 6c are door fitting steps, 20 is an inner panel, 7 is a door sash, 21
Is a glass run, 22 is an elevating glass, 7a is a dovetail-shaped weather strip attachment portion provided on the upper surface of the door sash 7, 7
Reference numeral b is a flange portion provided upright on the outer edge of the door touch 7. The rubber weather strip 8 has a flange portion 7b.
It has a groove portion 8a that fits into the dovetail groove, and a mounting base portion 8b that fits into the dovetail-shaped mounting portion 7a. When the door is closed, the hollow main seal portion 8d is a vertical portion of the door fitting step portion 6b. 6
In addition to contacting d, the door seal stepped part also contacted the horizontal part 6e, and the drip seal part 8c contacted the outer surface of the body outer panel 6a.

[Problems to be Solved by the Invention] Body outer panel 6a, door fitting steps 6b, 6
There are dimensional variations in each of the parts c, the door sash 7, the dovetail-shaped weather strip attachment portion 7a, the flange portion 7b, and the weather strip 8. Therefore, it is difficult to surely bring the main seal portion 8d and the drip seal portion 8c into contact with the fitting step portion 6b and the body outer panel 6a, respectively.

This invention is intended to surely bring the weather strip attached to the upper edge of the door sash into contact with the body outer panel and the door fitting step at the same time.

[Means for Solving Problems] A description will be given with reference to FIGS. 1 to 4.

In the vehicle door seal structure according to the present invention, a body outer panel 1a is provided with a small arc-shaped corner portion 1b and bent at an acute angle to form a door fitting step portion 1c, and a mounting base portion 2a,
The attachment bases 2a and 2j of the weather strip 2 composed of 2j and the hollow seal portion 2b are attached to the peripheral edge of the door sash 3, and the hollow seal portion 2b of the weather strip 2 is
Smoothly from the linear parting seal portion 2c, the "shi" shaped portion 2d folded back inward so as to overlap from the apex of the linear parting seal portion 2c, and the inward upward end on the indoor side of the "shii" shaped portion 2d. The "T" -shaped portions 2e connected to each other and the attachment bases 2a, 2 which are smoothly connected to the outer lower end of the "T" -shaped portions 2e.
Returning to j, the arcuate upper end of the "tsu" shaped portion 2e contacts the door fitting step 1c and is pushed by the step 1c when the door is closed. It is lowered and deformed so that the upper vertical portion 2g of the "shib" shaped portion 2d is brought into pressure contact with the body outer panel 1a, and the upward arc 2h of the bottom of the "shid" shaped portion 2d forms the small arcuate corner portion 1b of the body panel and The door fitting step portion 1c is configured so as not to be in contact with the door fitting step portion 1c.

[Embodiment] A first embodiment will be described with reference to FIGS. 1 to 3.

The body outer panel 1a is provided with a corner portion 1b with a small arc portion and bent at an acute angle to form door fitting step portions 1c and 1d.

The mounting base 2a of the weather strip 2 including the mounting base 2a and the hollow seal portion 2b is mounted on a dovetail-shaped mounting portion 3a provided on the peripheral edge of the door sash 3. The hollow seal portion 2b of the weather strip 2 includes a linear parting seal portion 2c, a "shib" shaped portion 2d that is folded back inward so as to overlap from the apex of the linear parting seal portion 2c, and the "stripe part". The "tsu" shaped portion 2e that is smoothly connected from the inward upward end on the indoor side of the "2" shaped portion 2d, and the inwardly convex shape that is smoothly connected to the outer lower end of the "tsu" shaped portion 2e and returns to the mounting base 2a. It is constituted by the large arc portion 2f.

When the door is closed, the arcuate upper end of the "T" shaped portion 2e comes into contact with the door fitting step portion 1c and is pushed down by the step portion 1c to be deformed, so that the upper vertical portion 2g of the "square" shaped portion 2d is deformed. It is configured so that it is pressed against the body outer panel 1a and the upward arc portion 2h of the bottom of the "square" shaped portion 2d is not in contact with the corner portion 1b with the small arc portion of the body panel.

3b is a vertical wall portion on the indoor side of the door sash 3, 3 is a glass run mounted on the outer side surface of the vertical wall portion, and 3c is a main seal member mounting portion provided overhanging on the vertical wall portion 3b on the indoor side. Main seal member 4 attached to main seal member attachment portion 3c
Is adapted to come into contact with the vertical wall of the door fitting step portion 1c for sealing. Reference numeral 10 is an inner panel, 12 is an elevating glass, and 13 is a molding layer formed on the outer surface of the parting seal portion 2c.

A second embodiment will be described with reference to FIG.

Instead of the dovetail-shaped mounting portion 3a in FIGS. 1 and 2, a flange portion 3d is provided upright on the outer edge of the peripheral edge of the door sash 3. A fitting groove 2k is provided in the mounting base portion 2j of the weather strip 2 so that the fitting groove 2k is press-fitted to the flange portion 3d.

[Operation] When the door is closed, the arcuate upper end of the "T" -shaped portion 2e comes into contact with the door fitting step portion 1c and is pushed down by the step portion 1c to be deformed, and the upper portion of the "shi" shaped portion 2d is vertically perpendicular. The portion 2g is pressed against the body outer panel 1a. At that time, the upward arc portion 2h of the bottom of the "square" shaped portion 2d is not in contact with the corner portion 1b with the small arc portion of the body panel and the door fitting step portion 1c.

[Effect of the Invention] Weather strip 2 of the door seal device according to the present invention
When the door is closed, as shown in FIG. 3, the upper end of the arcuate portion of the "U" shaped portion 2e contacts the door fitting step 1c and is pushed down by the step 1c as indicated by arrow A. It is deformed, and the upper portion 2g of the "square" shaped portion 2d is drawn to the body outer panel 1a as shown by the arrow B. At this time, "tsu"
By designing the deformation amount of the character portion 2e to be appropriately large, the allowable sealing range of the parting seal portion 2c can be increased. Therefore, it is possible to absorb the dimensional variation related to the door sash and maintain a sufficient sealing performance.

Further, the seal structure of the present invention can be applied to a flush surf ace door.
