Description

[Detailed Description of the Invention] This invention relates to an improvement in a sealing device for a door opening in an automobile body.

Automobiles are sometimes provided with doors that open and close on hinges at the rear. If a door is provided, the first
As shown in Figures 1 and 2, the rear inner panel 2 is overlaid on the rear pillar inner lower panel 1 and welded by spot welding, and an L is provided at the end of the rear pillar inner lower panel 1 and the rear inner panel 2. A rear pillar outer panel 4 is superimposed on the inside of the letter-shaped bend 3 and welded by spot welding. Furthermore, the ends of the outer panel 5 are overlapped and welded to the outer edge of the rear pillar outer panel 4 to form the rear part of the body. Then, a sealer 6 is applied to the overlapping edges to seal them. A weather strip 7 is attached to the L-shaped bend 3, and the protrusion 8 on the rear side is brought into elastic contact with the door 9 for sealing. In this case, water may enter the passenger compartment through the overlapped gaps between the rear pillar inner lower panel 1 and rear inner panel 2 and the rear pillar outer panel 4, so sealer 6 must be applied sufficiently. It won't be, but
Applying the sealer 6 so that there are no gaps is difficult, time-consuming, and increases manufacturing costs.

This idea is an improvement based on these points.
The embodiment of the present invention shown in FIGS. 3 and 4 will be described below.

The rear inner panel 2 is stacked and welded to the rear pillar inner lower panel 1, and the rear pillar outer panel 4 is stacked on the inside of the L-shaped bend 3 provided at the end of the rear pillar inner lower panel 1 and the rear inner panel 2. to weld. The point that the outer panel 5 is overlapped and welded to the rear pillar outer panel 4 is the same as that described in the conventional example. Therefore, the present invention provides a protrusion 8 along the rear side of the weather strip 7 attached to the L-shaped bend 3 so as to come into elastic contact with the door 9, and also provides a A tongue piece 10 is provided along the outer edge, and this tongue piece 10 is brought into elastic contact with the corner portion of the rear pillar outer panel 4, so that the rear pillar inner lower panel 1 and the rear inner panel 2 and the rear pillar outer panel 4 are overlapped. The mating part is located inside the tongue piece 10. Note that the upper end surface of the L-shaped bent 3 of the rear pillar inner lower panel 1 that overlaps the rear inner lower panel 2 is cut so as to be slanted downward toward the rear corner, as shown in Fig. 4. be.

The effect will be explained.

The overlapping and welding parts of the rear pillar inner lower panel 1 and rear inner panel 2 and the rear pillar outer panel 4 become the inner side sealed by the tongue piece 10 provided integrally with the weather strip 7. Therefore, even if there is some uncoated sealer 6, rainwater will not get in and the tongue piece 10
Can be sealed by In addition, the upper end surface of the L-shaped bend 3 of the rear pillar inner lower panel 1 is
The cut is slanted downward toward the rear corner, so that even if water gets in, the water that falls from the top will be collected at the corner of the rear pillar inner lower panel 1 and will be used as a weather strip. It is possible to prevent the water from going around the inside of the pipe 7 and flowing into the room.

As explained above, this invention overlaps the upper end of the rear pillar inner lower panel with the L-shaped bend integrally molded at the end and the lower end of the rear inner panel integrally molded with the L-shaped bend. A rear pillar outer panel is overlaid and welded on the inside of the L-shaped bend, and a rear pillar inner lower panel is attached to the upper end of the L-shaped bend integrally formed with the rear pillar inner lower panel. The weather strip, which is inclined downward toward the edge of the panel and attached to the L-shaped bend, has a protrusion on the rear side that comes into elastic contact with the door, and a rear pillar outer panel on the outer end. Since the rear pillar inner lower panel and the welded portion where the rear inner panel and the rear pillar outer panel are overlapped are on the inside of the tongue piece, the tongue piece is sealed. Therefore, the sealer can be applied easily and at low cost. In addition, the seal between the door and the body and the seal between the body and the outside air can be ensured.
Sealing performance indoors and outdoors can be improved.
Additionally, the tongue piece can be integrated with the weather strip, making it inexpensive. Furthermore, the upper end surface of the L-shaped bend,
The cut is slanted downward toward the rear corner, so even if water gets in, the water that falls from the top will be collected at the corner of the rear pillar inner lower panel, and the inside of the weather strip will be protected. This has the effect of being able to prevent the water from going around and flowing into the room.
