Description

[Detailed Description of the Invention] This invention relates to a mounting structure for a weather strip for a door glass of an automobile.

Weather strips for door glass are generally attached to the inner and outer panels at the bottom of the door window to prevent rainwater and dust from entering the inside of the door, and also to prevent the door glass from vibrating when the door is opened/closed or when the car is running. It is something to do. By the way, as a structure for attaching such a weather strip to a door panel, there is a structure as disclosed in Japanese Utility Model Application Publication No. 168420/1983. There is also another weather strip mounting structure as shown in FIG. In the figure, 2 is an outer door panel, and a flange portion 2a at the upper end thereof is provided with an L shape by bending the tip of the flange portion 2a further downward.
A weather strip holding portion 2b is formed in the shape of a letter, and a welding portion 2c is formed at the lower end of the holding portion 2b. A set plate 3 is attached to this holding portion 2b by spot welding its welded portion 3c to the welded portion 2c of the holding portion 2b.
The set plate 3 is formed with an inverted L-shaped weather strip holding portion 3b, and the holding portion 3b forms a U-shaped groove 6 together with the weather strip holding portion 2b. A protrusion 3d is provided at the upper end of the set plate 3 to protrude inward from the groove 6. A weather strip 5 is attached to the groove 6 by press-fitting its thicker engaging portion 5a, and a lip 5b is formed at the right end of the weather strip 5. is adapted to press against the door glass 4 when it is closed.

The mounting structure of the weather strip on the inner door panel 2' side is also similar to that of the outer door panel 2'.
In the figure, the inner door panel 2' side has the same reference numerals as the outer door panel 2 side. In addition, inner door panel 2'
A lip 5c is also formed at the lower end of the weather strip 5 on the side. Further, a belt line molding 7 is attached to the outer side of the flange portion 2a of the outer door panel 2 with screws.

According to such a conventional weather strip mounting structure, the set plate 3 is attached to the outer door panel 2 (the same applies to the inner door panel 2') by welding, which increases the number of parts.
Furthermore, there is a problem in that a large number of assembly steps are required, leading to high costs. Moreover, in order to hold the weather strip 5 in the U-shaped groove 6, the engaging part 5a is pushed into the groove 6 from above, and the protruding part 3d at the upper end of the groove 6 is engaged with the engaging part 5a. However, there was a problem in that the holding force of the weather strip 5 was weak and it easily came off upward.

This idea was made in view of the problems of the conventional ones, and the flange part at the upper end of the door panel has a U-shaped cross section with a hole for engagement with a weather strip on either side of the vertical wall. A weatherstrip with a U-shaped cross section is inserted into the groove, a molding clip having a protrusion is press-fitted into the weatherstrip, and the protrusion allows the weatherstrip to be attached to its vertical wall. By pressing outward to engage with the above-mentioned engagement hole,
The number of door panel parts and assembly man-hours can be reduced.
Another object of the present invention is to provide a mounting structure for a weather strip for an automobile, which has a strong holding force and prevents the weather strip from coming off upward.

An embodiment of the present invention will be described below with reference to the drawings.

2 to 4 show an embodiment of the present invention. In the figures, the door body 1 consists of an outer door panel 12 and an inner door panel 12', and an elevating glass 14 is provided between the two panels 12 and 12'. It is provided so that it can be moved up and down. Further, the flange portion 12a at the upper end of the outer door panel 12 has a U
A letter-shaped groove 12b is integrally formed at the bottom,
Vertical wall 12 on the outside of the vehicle body (left side in FIG. 3) of the groove 12b
A plurality of engagement holes 12d are opened at constant intervals in the longitudinal direction of the vertical wall 12c (in the direction perpendicular to the plane of the paper in the third drawing).

Further, a weather strip 15 having a U-shaped cross section is inserted into the groove 12b from above.
Lips 15c and 15d are provided at the upper and lower ends of the vertical wall 15b of the weather strip 15 inside the vehicle body (on the right side in the figure) to protrude upwardly toward the inside of the vehicle body. Flocking 15e made of nylon (trade name) or the like is applied to the lower surface of the lower part, so that it comes into pressure contact with the elevating glass 14 when the glass 14 is closed.

A molding clip 18 is press-fitted into the U-shaped groove of the weather strip 15 from above. The head is a band-shaped molding part 1 with chrome plating etc.
8a, and a pressing portion 18c is formed at the lower end of the leg portion 18b continuing downward from the molded portion 18a by further bending the leg portion 18b upward.
A plurality of projections 18d are formed on the pressing portion 18c at regular intervals in the longitudinal direction of the clip 18 (horizontal direction in FIG. 4), with a portion of the pressing portion 18c protruding outward. The protrusion 18d is connected to the vertical wall 15a of the weather strip 15 on the outside of the vehicle body.
A part of the vertical wall 15a is pressed to protrude outward from the vehicle body, thereby fitting a part of the vertical wall 15a into the engaging hole 12d, and the weather strip 15 is attached to the U-shaped part of the outer door panel 12. It is held in the groove 12b to prevent the weather strip 15 from coming off upward.

The mounting structure of the weather strip on the inner door panel 12' side is almost the same as that on the outer door panel 12 side, and the same reference numerals are used for the inner door panel 12' side in the figure as for the outer door panel 12 side.

As described above, according to the mounting structure of the automobile weather strip of this embodiment, the outer door panel 1
2 (Same for inner door panel 12')
Since a U-shaped groove 12b for attaching a weather strip is integrally formed on the upper end flange portion 12a,
The number of parts and the number of assembly steps for the door panel 12 can be reduced, and the cutting of the door panel 12 can be improved. In addition, a clip 18 that also serves as a molding is press-fitted into the weather strip 15, and a portion of the weather strip 15 is fitted into the engagement hole 12d of the door panel 12 using the protruding portion 18d, so that the weather strip 15 can be pressed into the weather strip 15. The molding 15 can be firmly held in the groove 12b to prevent it from coming off, and furthermore, no separate molding is required, and of course no molding installation work is required.

As described above, according to the automotive weather strip mounting structure according to the present invention, a U-shaped groove for holding the weather strip is integrally formed in the flange portion at the upper end of the door panel, and at least one of the grooves is An engagement hole is provided in the vertical wall, a weatherstrip is inserted into the groove, and a molding clip is press-fitted into the weatherstrip, so that the protrusion of the clip fits the weatherstrip into the engagement hole. As a result, the number of parts and assembly man-hours for the door panel can be reduced, the cutting of the door panel has been improved, and costs have been reduced, and the holding power of the weather strip has been strengthened to prevent it from falling off. Furthermore, there is no need for a separate molding, and the molding installation work can be omitted.
