Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sub-seal device in a sliding roof device for a vehicle.

More specifically, in a sliding roof device that opens and closes a ceiling opening of a vehicle with a sliding roof member, a sub-seal member is provided at the rear end of the roof member to enter the lower surface of the ceiling around the opening, and the sub-seal is provided with a sub-seal member that enters the lower surface of the ceiling around the opening. a first lip on the side, and a first lip provided in front of the first lip;
This sub-seal device is provided with a second lip that is formed to be slightly inclined forward and does not contact the lower surface of the ceiling, and that reliably prevents water droplets from entering a vehicle interior when a roof member is opened.

2. Description of the Related Art Sliding roof devices are already known in which an opening is provided in the ceiling of a vehicle and the opening is opened and closed by a sliding roof member.

The sliding roof member of the sliding roof device described above is equipped with a main seal member for sealing the inner periphery of the opening, which ensures airtightness when the opening is closed, prevents the intrusion of rainwater, etc. Drainage grooves are provided on the frame side at the front and left and right sides to catch and drain remaining raindrops adhering to the roof and roof members.

However, in the rear part, the roof member tilts downward and moves rearward to be stored on the lower surface of the rear part of the ceiling, so it is not possible to provide the above-mentioned drainage groove.

Therefore, conventionally, a sub-seal is provided as shown in FIG.

That is, 1 is a ceiling, and a sliding roof member 3 that closes an opening 2
A sub-seal 5 is provided at the rear end portion, and includes a lip 6 that extends rearward together with the main seal portion 4, stands diagonally upward, and contacts the lower surface of the periphery of the opening 2.

When the roof member 3 is initially opened, that is, when the roof member 3 is initially tilted downward, the sub-seal 5 receives rainwater and the like adhering to the top surface of the roof member 3, and drains it into drains on both sides.

In the above, the lip part 6 is one step, and fatigue occurs in this part due to contact bending with the lower surface of the ceiling, and rainwater etc. on the roof member 3 is caused by inertia due to the forward movement of the vehicle. As shown by the arrow in FIG. 5, there is a risk that rainwater may cross over the lip portion 6 and enter the rear part of the vehicle compartment, and the function of the lip portion 6 to prevent rainwater from entering is not reliable.

The present inventor has devised the present invention in view of the above-mentioned problems of the sliding roof device and to effectively solve the problems.

The purpose of the present invention is to provide a first lip portion in contact with the lower surface of the ceiling at the rear of the sliding roof member, a second lip portion located in front of this lip portion that is slightly inclined forward, and does not contact the lower surface of the ceiling; The first lip seals the lower surface of the ceiling and the sub-seal, and the second lip guides rainwater to the drainage ditch when the roof member is initially tilted when the roof member is opened. To provide a sub-seal device which reliably and effectively prevents rainwater from entering a vehicle interior when a roof member is opened by preventing the intrusion into a vehicle interior by a first lip part.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is an explanatory plan view showing the main parts of the vehicle ceiling;
The figure is an enlarged sectional view of the main part taken along the line 2-2 in FIG.

An opening 12 is formed in the front part of the ceiling 11 of the vehicle 10,
A slide roof member 13 that is slidable back and forth with guide rails (not shown) provided on the left and right sides faces the opening 12,
The roof member 13 opens and closes the opening 12, and the roof member 13 moves up and down in the opening 12 when opening and closing.

A main seal member 1 made of rubber or the like is provided around the entire circumference of the roof member 13.
The main seal member 14 has a lip portion 14a and a bulge portion 14b to enhance the sealing effect.
is provided on the outer periphery.

On the other hand, an acid tapered molding 15 is provided around the opening 12 of the ceiling 11 so as to expand the opening downward, and the lower surface of the ceiling 11 is covered with a backing plate 16.
The rear area around the opening is flat.

A base portion of a sub-seal plate holder 17 is connected and supported on the rear lower surface of the roof member 13, and the holder 17 extends rearward to the rear lower surface around the opening 12 when the roof member 13 is closed.

A sub-seal 18 made of rubber or the like is provided at the rear of the holder 17 by baking and integrating the sub-seal 18 and the holder 1.
7 is provided over the entire width in the width direction of the opening 12, and is provided slightly longer than this.

The sub-seal 18 is provided with a first lip portion 19 at the rear that stands diagonally backward and upward, and in the illustrated example, the upper end portion of the lip portion 19 is bent slightly forward, and this lip portion 19 is bent when the roof member 13 is closed. The tip is set so as to elastically contact the peripheral rear lower surface 16a of the ceiling opening 12.

On the other hand, a second lip part 20 is provided upright on the rear lower surface 16a of the opening 12 in front of the first lip part 19.
The lip portion 20 is erected in the opposite direction to the first lip portion 19, that is, with a slight inclination toward the front, and the height of the lip portion 20 increases when the roof member 13 is closed, as shown in FIG. A gap S is maintained between the rear lower surface 16a and the tip of the lip portion 20 is set so as not to contact the lower surface 16a.

The lip 19, 20U sub-seal member 18 described above is molded entirely in one piece.

FIG. 2 shows a closed state of the roof member 13, in which the lip 14a and the bulging portion 14b of the main seal member 14 are connected to the molding 1.
The first lip portion 19 of the sub-seal 18 comes into elastic contact with the inner peripheral wall of the sub-seal 18 to provide a seal, and the tip of the first lip portion 19 of the sub-seal 18 contacts the rear lower surface 16a around the opening to provide a double seal.

By the way, when the roof member 13 is opened, the rear part of the roof member 13 descends and slopes at the initial stage of opening.

This is shown in Figure 3. Rainwater or the like on the roof member 13 passes over the main seal member 14 and falls in front of the second lip portion 20 of the sub-seal 18, where it is guided to the left and right drains.

Since this lip portion 20 is inclined forward, it prevents rainwater and the like from flowing backward.

When the water exceeds the multi-lip portion 20, the first lip portion 19 is located behind this portion, so that the water is dammed up by this portion and water is prevented from flowing out to the rear.

In this way, rainwater is doubly blocked and prevented from entering the vehicle interior, and the forward tilting of the second lip portion 20 provides an extremely high prevention effect.

By the way, although the second lip portion 20 does not touch the lower surface of the ceiling,
This was done in consideration of the fact that contact would cause slight deformation over time, and in order to fully demonstrate the water damming effect without deformation, it was decided not to contact.

As is clear from the above, according to the present invention, the roof member is provided with a double lip portion, and the second lip portion for blocking water is not in contact with the lower surface of the ceiling, which is the sealing surface, and is tilted forward. It is possible to reliably and effectively prevent rainwater from entering the vehicle interior due to the tilting at the initial stage of opening.

In addition, it is sufficient to simply provide double lips on the sub-seal, and since the sub-seal is also molded from rubber etc., the structure is simple.
In addition, the above can be achieved easily and inexpensively, and it is highly practical as it is convenient for practical use of sliding roof devices.
