Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal structure for an openable roof vehicle in which a vehicle body opening formed in an upper portion and a rear portion of a vehicle compartment is opened and closed by a movable roof.

[0002]

2. Description of the Related Art As is well known, various types of open / close roof vehicles, which are so-called convertible sedans capable of opening / closing the roof of a vehicle body, are provided (for example, see Japanese Utility Model Laid-Open No. 1-165716). ).

That is, as shown in FIG. 5, the openable roof vehicle 1 has a vehicle body opening 2 formed in an upper portion and a rear portion of a vehicle compartment, and the vehicle body opening 2 can be opened and closed by a movable roof 3. The movable roof 3 includes a front roof 3a made of a hard synthetic resin plate that covers the upper portion of the vehicle body opening 2, and a rear roof 3b that is foldably connected to the front roof 3a and covers the rear portion of the vehicle body opening 2. .. The rear roof 3b is formed of a rigid body such as a synthetic resin material, and both lower ends of the rear roof 3b are rotatably supported by the vehicle body 1 through a pair of pivotally supporting members, and the back window glass 4 is attached to the center thereof. ing.

A storage space 5 for accommodating the movable roof 3 at the time of opening the vehicle body opening 2 is provided in the rear portion of the vehicle body, and the upper space of the storage space 5 is pivotally supported at the rear end portion of the vehicle body. The storage cover 6 is opened and closed. A weather strip 7 having a circular cross-section and made of a synthetic rubber material is attached to the periphery of the upper opening of the storage space 5. This weather strip 7 is shown in FIG.
As also shown in FIG. 3, the storage space other than the location where the movable roof 3 is installed is fitted and fixed to the flange portion 8 which is erected on the opening peripheral edge of the storage space 5 via the notch portion which is cut out in the radial direction. 5 is disposed on the periphery of the upper opening.

On the other hand, a substantially linear seal member 9 is provided at the rear edge of the rear roof 3b. The seal member 9 is made of a synthetic rubber material, and has a base portion 9a fixed to the rear end edge of the rear roof 3b with an adhesive or the like, and a seal which integrally has a lower end portion of the base portion 9a and forms a drip channel 10 inside. It is mainly composed of a lip 9b.

When the vehicle body opening 2 is closed, the movable roof 3 folded in the storage space 5 is pulled out, slidably moved to a predetermined position along the periphery of the vehicle body opening 2 and stopped by a predetermined stopper. For example, both ends 7a of the weather strip 7 and both ends 9c of the seal member 9 are continuously joined at the same time when the closing work is completed. Then, when the storage space 6 is closed by the storage cover 6, the inner peripheral edge of the storage cover 6 comes into pressure contact with the upper edge of the weather strip 7 and the upper end of the seal lip 9b to seal the storage space 5. There is. As a result, for example, rainwater flowing from the front roof 3a along the rear roof 3b can be prevented from flowing into FIG.
As shown by the arrow, it reaches the drip channel 10 of the seal member 9 and is divided into two sides from here to be discharged to the outside through the trough portion 11 on the outer peripheral side of the weather strip 7, respectively.

[0007]

However, in the above-mentioned conventional seal structure, the weather strip 7 and the facing ends 7a and 9c of the seal member 9 are joined to each other when the movable roof 3 is in use as described above. However, due to variations in the mounting accuracy of the weather strip 7 and the seal member 9 and errors in the processing accuracy during manufacturing, the adhesiveness of the joint ends 7a and 9c is unsatisfactory. There is a possibility that the gap S is sufficient and a gap S is generated between the two. Therefore, in particular, high-pressure water (strong water discharge) such as car wash water enters from between the rear end side edges of the movable roof 3 and the vehicle body, enters the clearance S, and drips into the storage space 5 as it is. It wraps around from S to the back surface 9d side of the seal member 9 and drops from the bottom edge of the seal lip 9b into the storage space 5 as it is.

[0008]

The fitting portion 47 is for fitting to the bent outer end edge of the wind frame 23c to position and fix the seal member 42, and the gutter lip 51 is provided at the lower end edge of the outer piece. It is integrally provided along the longitudinal direction.

The gutter lip 51 is bent in a substantially V-shape from the approximate center toward the movable roof 23 side, and a water passage 52 is formed inside the bend of the upper piece 51a and the lower piece 51b. There is. A gap 53 is provided between the tip edge of the lower piece 51b and the back surface of the wind frame 23c. Further, drainage holes 54 are formed at both ends of the lower piece 51b of the gutter lip 51, that is, at both ends located above the drainage grooves 40.

Therefore, according to this embodiment, when the movable roof 23 covers the opening 22 of the vehicle body and the lid 26 closes the storage space 25, both sides of the vehicle body and the movable roof can be washed. The car wash water that has entered from between the both side edges of the rear part of 23 enters the gap S between the joint ends 28a, 42a of the weather strip 28 and the seal member 42 as it is, and a part of the car wash water is the outer end part of the wind frame 23c. Although it wraps around to the back surface 23e side of 23d and flows down toward the outer edge, it is received here in the water passage 52 inside the gutter lip 51. Further, it flows through the water passage 52, falls from the drain hole 54 into the drain groove 40, and is immediately discharged as it is from the drain hole 41 to the outside of the vehicle.

The car wash water that has flowed through the gap S as it is is directly received in the drain groove 40, merges with the water from the water passage 52, and is discharged from the drain hole 41 to the outside of the vehicle.

Further, the water leaked to the outside from the upstream end side of the drainage groove 40 flows down into the gutter groove 36 and is discharged from the vehicle through the drainage hole 37 to the outside of the vehicle.

Furthermore, at the time when both ends 42a of the seal member 42 are joined to both ends 28a of the weather strip 28, the lower surface of both ends 42a of the seal member 42 is the shelf 3.
8 is pressed against and stably supported, and the sub seals 31 and 45, the main seals 32 and 48, and the inner and outer gutter portions 34, 49, and 3
It is possible to prevent the vertical displacement of 5 and 50 from each other to maintain continuity, and improve the pressing force of the joint ends 28a and 42a in the longitudinal direction, thereby sufficiently preventing the occurrence of the gap S. Moreover, since both end portions 42a of the seal member 42 are firmly fixed to the wind frame 23c by the bolts 43, the both end portions 42a are prevented from being lifted from the wind frame 23c and are reliably positioned and fixed. Therefore, continuity and pressure contact force with the weather strip 28 are promoted.

[0022]

As is apparent from the above description, according to the seal structure for the openable roof vehicle of the present invention, the car wash water that has entered through the gap between the joint ends of the weather strip and the seal member remains as it is. What has flowed down is received in the drainage channel and discharged to the outside of the vehicle, but what has flowed around the back side of the seal member is received in the water passage of the gutter lip,
Since it flows toward both ends and is discharged from the vehicle through the drainage groove to the outside of the vehicle, it is possible to sufficiently prevent the car wash water and the like from dripping into the storage space.
