Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sunroof seal structure, and more particularly to a sunroof seal structure in which a weather strip is fitted onto a downwardly bent flange on the outer peripheral edge of a sunroof panel for sealing.

Generally, in the sealing structure of a sunroof, a sealing material 4 is provided between a sunroof panel 1 and a roof panel 2, as shown in FIG. 1, to seal the inside and outside of the sunroof when the sunroof is closed.

However, in such cases, a sealing material exclusively for sunroofs has conventionally been designed and manufactured, and since the production volume of sunroof vehicles is smaller than that of general vehicles, the cost has been high.

Therefore, as shown in FIG. 2, it is conceivable to use the existing weather strip 5 used for the edges of vehicle body openings such as trunks, etc., also as the sealing material 4 for the sunroof.

As shown in FIG. 2, the weather strip 5 for the vehicle body opening edge has a draining lip 7 protruding from the upper end of the inner peripheral edge of the substantially U-shaped base 6, which is in close contact with the vehicle body opening edge flange. Flange retaining lips 8, 8', 9, 9' are protruded from the inner circumferential side and are opposed to each other.

Furthermore, a main lip 10 is formed on the outer surface of the base 6.

Such an existing weather strip for the opening edge of the vehicle body 5
When used as the sunroof sealing material 4 as is, the flange portion 1 of the sunroof panel 1
1 is facing downward, and when the weather strip 5 is attached to the flange portion 11, the base portion 6
Because the opening of the drainer lip 7 faces upward, and because the draining lip 7 receives the water pressure of rainwater and car wash water flowing down from the sunroof panel 1 and the roof panel 2, water flows into the space between the flange portion 11 and the draining lip 7. Water that has entered space A gradually enters spaces B and C between the flange retaining lips 8 and 9 on the outdoor side and flange part 11 and remains there. There was a problem in that the outer peripheral edge of the sunroof panel 1 was susceptible to rust and corrosion due to accumulated water.

In view of such conventional circumstances, the present invention has been developed by providing a drainage hole at the bottom of the base of the weather strip when the weather strip generally used on the edge of the opening of the vehicle body is used as a weather strip for a sunroof. The water that enters the base is discharged to the outside of the weather strip, thereby preventing rust and corrosion on the outer edge of the sunroof panel. are given the same reference numerals and will be described in detail.

That is, in the present invention, as shown in FIG. 3, a draining lip 7 is provided on the upper end of the inner peripheral edge of the substantially U-shaped base 6, and a flange holding lip 8 is provided on the inner peripheral side of the base 6.
The weather strip 5 having protruding portions 8', 9, 9' and a main lip 10 attached to the outer surface of the base is attached by fitting the base 6 to the downward flange 11 of the outer periphery of the sunroof panel 1. In this configuration, a drainage hole 13 is provided in the bottom 12 of the base 6.

An appropriate number of drain holes 13 may be provided depending on the length of the weather strip 5.

The close contact area 14 between the main lip 10 and the sunroof opening edge is connected to the sunroof panel 1 or the roof panel 2.
There is a risk of water leaking from the contact area 14 due to the water pressure of falling rainwater or car wash water, so the roof panel 2 is
A drain groove 2' is formed at the end of the roof panel, and a drain port 15 is provided at each corner of the roof panel so as to communicate with the drain groove 2'.A drain pipe 16 is connected to the drain port 15 to drain the outside of the vehicle. It is designed so that it can be discharged to

The drain hole 13 is configured to be located at the upper part of the drain groove 2', and the water flowing down from the drain hole 13 is
The water flows down through the drain pipe 16 from the drain port 15 through the drain groove 2' and is discharged to the outside of the vehicle.

In addition, by forming drainage notches in the flange holding lips 8 and 9 on the outdoor side and forming a drainage passageway leading to the drainage hole 13, water that has entered into the spaces A and B can be efficiently removed. It can be made to flow down to the drain hole 13.

As described above, according to the present invention, a water drain hole 13 is provided in the existing weather strip 5 that is generally used on the edge of the opening of a vehicle body, and the weather strip 5 is also used as a weather strip for a sunroof. Thus, there is no need to design and manufacture a sunroof-specific sealing material 4, and moreover, effective sealing performance can be ensured, reducing costs.

In addition, water flowing down from the roof panel 2 and the sunroof panel 1 flows through the draining lip 7 of the weather strip 5 and the flange retaining lip 8 on the outdoor side.
Even if the water enters the spaces A, B, and C between the sunroof panel 9 and the flange portion 11, the intruding water can be efficiently drained from the drain hole 13, thereby solving the problem of rust and corrosion on the outer peripheral edge of the sunroof panel. This excellent effect can be achieved.

Claims (1)

[Scope of utility model registration request] A weather strip base having a substantially U-shaped cross section is fitted onto a flange portion bent downward on the outer periphery of the sunroof panel with its opening facing upward, and a main lip formed on the outside surface of the base is attached to the flange portion of the sunroof panel. In a configuration in which the weather strip is brought into close contact with the opening edge of the sunroof to seal the interior and exterior of the vehicle interior, a drainage hole is provided at the bottom of the weather strip base;
A seal structure for a sunroof, characterized in that rainwater that has entered the base is discharged from the drainage hole into a drain groove formed at an end of the roof panel.
