The present invention relates to a sealing structure for a motor vehicle with a retractable roof including a front-side roof and a rear-side roof. The motor vehicle has a cabin that has its upper end opened and closed by the retractable roof.
Exemplary known retractable roofs described above include a retractable roof which includes a front roof and a middle roof as a front-side roof, and a deck cover as a rear-side roof, and which opens and closes an upper end of the vehicle cabin, as disclosed in Patent Document 1.
In general, the front-side roof is provided with a roof-side weatherstrip, and pillars of a vehicle body are each provided with a pillar-side weatherstrip.
When the retractable roof is to be closed, the pillar-side weatherstrip is pushed by a side window of an associated side door so that the roof-side weatherstrip is pushed inward in the vehicle width direction by the pillar-side weatherstrip. As a result, a gap is formed between the pillar-side weatherstrip and a front portion of the deck cover.
To prevent the formation of the gap, the roof-side weatherstrip may have a lip portion caught on an outer surface of the side window in the vehicle width direction. When the roof is to be closed, the lip portion may prevent the roof-side weatherstrip from being pushed inward in the vehicle width direction.
In this case, when the front roof and the middle roof are retracted, the lip portion is retracted in a storage compartment together with the front-side roof. Thus, the gap described above is left between the pillar-side weatherstrip and the front portion of the deck cover. Under the influence of travel wind having a relatively high velocity and a relatively low pressure against the inside of the deck cover, air is sucked out of the vehicle through the above-described gap, thereby generating noise (suction sound).
That is to say, air flowing rearward along the upper portion of the pillar is sucked out of the vehicle through the gap by an air stream flowing along a side surface of the vehicle body and having a higher velocity and a lower pressure than the air, thereby generating noise.

The present invention is thus intended to provide a sealing structure for a motor vehicle with a retractable roof, the sealing structure being capable of blocking the gap with a roof open and preventing wind suction sound, without hindering the sealing performance of a lip portion of the sealing structure while the roof and a side window are closed.
A sealing structure for a motor vehicle with a retractable roof according to the present invention is directed to a sealing structure for a motor vehicle with a retractable roof including a front-side roof and a rear-side roof, the motor vehicle having a cabin that has an upper end opened and closed by the retractable roof. Side windows are provided in front of respective side surfaces of the rear-side roof. Corner portions of an upper edge of the rear-side roof close to the side windows each protrude toward a front of the vehicle beyond a rear frame portion of an associated one of the side windows. Pillars provided on a vehicle body are positioned on the respective corner portions inside the vehicle. Front-side roof-side weatherstrips attached to the front-side roof each include a lip portion, the lip portion being positioned to cover an upper end portion of an associated one of the pillars from outside of the vehicle while the roof is closed. Sealing members are respectively provided on the corner portions of the rear-side roof close to the side windows inside the vehicle. An extended sealing portion extends from each sealing member, the extended sealing portion blocking a gap while the front-side roof is open, the gap being formed between an associated one of the corner portions and an associated one of the pillars and intended for the lip portion. The extended sealing portion is positioned to sandwich the lip portion of the front-side roof-side weatherstrip between the extended sealing portion and the pillar while the roof is closed.
The front-side roof may include a front roof and a middle roof. The rear-side roof may include a deck cover. Further, a frame portion of each side window may be constructed of, for example, a roof, a front pillar, a center pillar, and a deck cover. The rear frame portion of the side window means a rear portion of the frame portion.
According to this configuration, the extended sealing portion is provided to block a major portion of the gap from the sealing member inside the vehicle. Thus, the extended sealing portion blocking the gap can prevent wind suction sound (noise) arising from the air stream flowing along a side surface of the vehicle body. In addition, the extended sealing portion extending from the inside of the vehicle pushes the lip portion from outside the vehicle while the roof is closed. This helps position the lip portion.
In one embodiment of the present invention, a trim strip may be provided on the rear frame portion of each of the side windows outside the vehicle, and a front end portion of the trim strip and a rear edge of the extended sealing portion may engage with each other while overlapping each other with the front end portion of the trim strip located inside the rear edge of the extended sealing portion.
According to this configuration, the extended sealing portion inside the vehicle and the trim strip outside the vehicle engage with each other while overlapping each other with the front end portion of the trim strip located inside the rear edge of the extended sealing portion. This can improve the persistence of the positioning accuracy without rigidifying the extended sealing portion, such as providing a core material in the extended sealing portion.
More specifically, even though the extended sealing portion and the trim strip are each formed of a flexible member, these flexible members, which have high durability in the tensile direction, pull each other toward the associated attachment region (an associated one of the inside and outside of the vehicle cabin), thereby improving the persistence of the positioning accuracy.
In one embodiment of the present invention, an upper portion of each of the pillars may have a recess receiving the retractable roof and extending in a longitudinal direction of the vehicle.
This configuration allows the recess to support the retractable roof on the upper portion of the pillar without misalignment, and can effectively prevent wind flowing in the direction of the gap along the recess (the pillar recess) from causing suction sound. That is to say, the retractable roof can be supported, and suction sound can be prevented.
According to the present invention, while the roof is open, the gap can be blocked, and wind suction sound can be prevented, without hindering the sealing performance of a lip portion while the roof and an associated side window are closed.
The objective of blocking a gap with a roof open and preventing wind suction sound, without hindering the sealing performance of a lip portion while the roof and a side window are closed is attained by the following features of a sealing structure for a motor vehicle with a retractable roof including a front-side roof and a rear-side roof, the motor vehicle having a cabin that has an upper end opened and closed by the retractable roof. Specifically, side windows are provided in front of respective side surfaces of the rear-side roof, corner portions of an upper edge of the rear-side roof close to the side windows each protrude toward a front of the vehicle beyond a rear frame portion of an associated one of the side windows, pillars provided on a vehicle body are positioned on the respective corner portions inside the vehicle, front-side roof-side weatherstrips attached to the front-side roof each include a lip portion, the lip portion being positioned to cover an upper end portion of an associated one of the pillars from outside of the vehicle while the roof is closed, sealing members are respectively provided on the corner portions of the rear-side roof close to the side windows inside the vehicle, an extended sealing portion extends from each sealing member, the extended sealing portion blocking a gap while the front-side roof is open, the gap being formed between an associated one of the corner portions and an associated one of the pillars and intended for the lip portion, and the extended sealing portion is positioned to sandwich the lip portion of the front-side roof-side weatherstrip between the extended sealing portion and the pillar while the roof is closed.
An embodiment of the present invention will now be described with reference to the drawings.
The drawings illustrate a sealing structure for a motor vehicle with a retractable roof.

As can be seen, a sealing structure for a motor vehicle with a retractable roof according to the embodiment is a sealing structure for a motor vehicle with a retractable roof 20 including a front-side roof 23 and a rear-side roof (see a deck cover 24), the motor vehicle having a cabin that has an upper end opened and closed by the retractable roof 20. Side windows 7 are provided in front of respective side surfaces of the rear-side roof (the deck cover 24). Corner portions 24X of an upper edge of the rear-side roof (the deck cover 24) close to the side windows each protrude toward a front of the vehicle beyond a rear frame portion of an associated one of the side windows 7. Pillars 31 provided on a vehicle body are positioned on the respective corner portions 24X inside the vehicle. Front-side roof-side weatherstrips 34 attached to the front-side roof 23 each include a lip portion 34b, the lip portion 34b being positioned to cover an upper end portion of an associated one of the pillars 31 from outside of the vehicle while the roof is closed. Sealing members 40 are respectively provided on the corner portions 24X of the rear-side roof (the deck cover 24) close to the side windows inside the vehicle. An extended sealing portion 40b extends from each sealing member 40, the extended sealing portion 40b blocking a gap g1 while the front-side roof 23 is open, the gap g1 being formed between an associated one of the corner portions 24X and an associated one of the pillars 31 (specifically, the pillar-side weatherstrips 32) and intended for the lip portion 34b. The extended sealing portion 40b is positioned to sandwich the lip portion 34b of the front-side roof-side weatherstrip 34 between the extended sealing portion 40b and the pillar 31 (see the pillar-side weatherstrip 32) while the roof is closed (see
According to this configuration, the extended sealing portion 40b is provided to block a major portion of the gap g1 from the sealing member 40 inside the vehicle. Thus, the extended sealing portion 40b blocking the major portion of the gap g1 can prevent wind suction sound (noise) arising from the air stream flowing along a side surface of the vehicle body. In addition, the extended sealing portion 40b extending from the inside of the vehicle pushes the lip portion 34b while the roof is closed. This helps position the lip portion.
In one embodiment of the present invention, the trim strip 42 is provided on the rear frame portion of the side window 7 outside the vehicle, and the front end portion of the trim strip 42 and the rear edge of the extended sealing portion 40b engage with each other while overlapping each other in the inside-to-outside direction of the vehicle cabin (see
According to this configuration, the extended sealing portion 40b inside the vehicle and the trim strip 42 outside the vehicle engage with each other while overlapping each other in the inside-to-outside direction. This can improve the persistence of the positioning accuracy without rigidifying the extended sealing portion 40b, such as providing a core material in the extended sealing portion 40b.
More specifically, even though the extended sealing portion 40b and the trim strip 42 are each formed of a flexible member, these flexible members, which have high durability in the tensile direction, pull each other toward the associated attachment region (an associated one of the inside and outside of the vehicle cabin), thereby improving the persistence of the positioning accuracy.
Furthermore, in one embodiment of the present invention, an upper portion of each of the pillars 31 (more specifically, see the pillar-side weatherstrips 32) has a recess 33 receiving the retractable roof 20 and extending in the longitudinal direction of the vehicle (see
This configuration allows the recess 33 to support the retractable roof 20 on the upper portion of the associated pillar 31 without misalignment, and can effectively prevent wind flowing in the direction of the gap g1 along the recess 33 (the pillar recess) from causing suction sound. That is to say, the retractable roof 20 can be supported, and suction sound can be prevented.
In the correspondence between components of the present invention and those of the foregoing embodiment, the rear-side roof of the present invention corresponds to the deck cover 24 of the embodiment. However, components of the foregoing embodiment are merely examples of the present invention.
For example, in the foregoing embodiment, the front roof 21 and the middle roof 22 form the front-side roof 23. However, the front-side roof 23 may include only the front roof.
The extended sealing portion 40b is configured to block a major portion of the gap g1. However, this configuration is merely an example of the present invention. The extended sealing portion 40b may block the entire gap g1.
As can be seen from the foregoing description, the present invention is useful for a sealing structure for a motor vehicle with a retractable roof including a front-side roof and a rear-side roof. The motor vehicle has a cabin that has its upper end opened and closed by the retractable roof.
