Description

  In the present invention, for example, a roof panel attached to a vehicle body roof opening of an automobile is divided into a plurality of roof panels, at least one of which is a sliding roof panel, and the sliding roof panel and other divided roofs. The present invention relates to a sealing structure for an automobile that seals between panels.

  Conventionally, as shown in FIG. 7, in an opening 2 of a vehicle body roof 1 of an automobile and a roof panel 110 that opens and closes the opening 2, the roof panel 110 is constituted by a single panel without being divided. Is often used. The weather strip that seals between the roof panel 110 and the vehicle body roof opening 2 is a sliding roof weather strip 50 attached around the roof panel 110 as shown in FIG. For this purpose, the mounting base 51 and the hollow seal 52 are formed. The mounting base portion 51 is formed with a trim portion having a substantially U-shaped cross section so that the sliding roof weather strip 50 can be mounted by sandwiching the glass panel of the sliding roof and inserting the flange portion of the frame. Yes.

A hollow seal portion 52 is integrally formed on the outer wall of the attachment base portion 51, and the hollow seal portion 52 is in contact with the peripheral portion of the vehicle body roof opening 2. Thus, sealing can be performed between the vehicle body roof opening 2 and the hollow seal portion 52 (see, for example, Patent Document 1).
In this case, the attachment base 51 for attaching the weather strip to the roof panel 110 may become large and the weight may increase.
FIG. 8 is a partial cross-sectional view taken along line BB in FIG.

Further, there has been a demand to increase the opening of the vehicle body roof 1 in order to brighten the passenger compartment, improve the air flow, improve the feeling of opening, and improve the view.
In this case, when the roof panel 110 is a single panel, the roof panel 110 that slides when the opening is opened is also heavier and heavier, the distance to which the roof panel 110 moves rearward becomes longer, and the driving mechanism is also improved. In addition to the increase in size, the design was not desirable, and the sliding roof panel might protrude beyond the rear of the vehicle body.

Thus, it has been attempted to divide the roof panel 110 into a plurality of roof panels in the front-rear direction of the vehicle body, but a seal between the divided roof panels 110 is necessary.
In order to seal between the divided roof panels 110, there is a type in which weather strips are attached and sealed to the rear end portion of the front roof panel 110 and the front end portion of the rear roof panel 110, respectively (for example, (See Patent Document 2).

However, attaching weather strips to both roof panels 110 is time consuming and costly.
In addition, there is a case where the weather strips are not necessarily brought into contact with each other properly due to variations in assembly of both roof panels 110, 110, and changes in the shape of the weather strips attached to both.
In addition, in order to improve the sealing performance, some weather strips are provided with a hollow seal portion. However, when the hollow seal portion is compressed and the seal wall comes into close contact with the mounting base portion, the roof panel 110 is opened. In some cases, the seal wall is in close contact and the hollow seal portion remains crushed, and abnormal noise may be generated when the seal wall is released elastically. Furthermore, the hollow seal portion may be compressed, and the hollow seal portion may protrude outward from between the roof panels 110, resulting in poor appearance.

Further, when there are three divided roof panels 110, there are some that slide the two roof panels 110, 110 on the rear side together (for example, see Patent Document 3).
In this case, the mechanism for sliding the roof panel 110 becomes large-scale, and the seal between the roof panels 110 and the seal between the roof panel 110 and the vehicle body roof opening are complicated.
Therefore, an attempt has been made to reduce the number of sliding roof panels that slide among the divided roof panels 110, for example, to have one sliding roof panel.

In this case, the seal between the sliding roof panel and the other roof panel may be performed by attaching a weather strip to the sliding roof panel or by attaching it to the base member of the vehicle body roof opening 2.
When the weather strip is attached to the base member 3 of the vehicle body roof opening 2, when the sliding roof panel 12 is slid and closed as shown in FIG. The weather strip 120 contacts and seals. At this time, an inner weather strip 140 is attached to the inside of the lower surface of the sliding roof panel 12 for double sealing.

In this case, for example, when a high-pressure car wash is performed, as shown in FIG. 10, high-pressure water directly strikes the gap between the sliding roof panel 12 and the roof panel 11, and the hollow seal portion 126 of the weather strip 120 is recessed. There is a case where the high-pressure water passes through the surface of the hollow seal portion 126 and enters under the sliding roof panel 12, hits strongly between the inner weather strip 140 and the sliding roof panel 12, and spreads between them to enter the vehicle. It was.

  Accordingly, the present invention divides a roof panel for opening and closing a vehicle body roof opening of an automobile into a plurality of parts, and a weather strip hollow seal that seals between the sliding roof panel and the other roof panel among the divided roof panels. An object of the present invention is to provide a sealing structure for a sliding roof for an automobile that does not enter the vehicle compartment even when high pressure water dents the weather strip by providing a bent portion at the portion.

The present invention of claim 1 is a sliding roof panel in which a plurality of roof panels divided in the longitudinal direction of a vehicle body are attached to a vehicle body roof opening of an automobile, and at least one of the divided roof panels slides. Yes, in a sliding structure for a sliding roof for automobiles that seals between a sliding roof panel and another roof panel with a weatherstrip,
The vehicle body roof opening is provided with a base member for mounting the weather strip at a position below the plurality of roof panels.
The weather strip is provided with a base portion attached to the base member and a hollow seal portion that is integrally formed on the base portion and seals between the divided roof panels. A pair of hollow seal portion side walls and a pair of hollow seal portion side walls that are continuous between the other end of the pair of hollow seal portion side walls and seal between a sliding roof panel and another roof panel are configured. At least one hollow seal part side wall of the seal part side wall is formed by bending, and has a sliding structure for a sliding roof for an automobile.

In the present invention of claim 1, since the roof panel divided into a plurality in the longitudinal direction of the vehicle body is attached to the vehicle body roof opening, the size of each roof panel is increased even if the vehicle body roof opening is enlarged. The vehicle body roof opening can be easily enlarged, the interior of the vehicle can be brightened, the view can be improved, and the feeling of opening can be improved.
A sliding roof panel in which at least one roof panel of the divided roof panels slides, and at least one of the other roof panels does not slide. The mechanism for driving can be easily reduced.
Since the space between the sliding roof panel and another roof panel is sealed with a weather strip, the roof panels can be reliably sealed even when the roof panels are divided.

The vehicle body roof opening is located below the roof panels and is provided with a base member to which the weather strip is attached, so there is no need to attach the weather strip to the roof panel, and the roof panel should be lightened. And the sliding drive mechanism of the sliding roof panel can be simplified.
The weather strip includes a base portion attached to the base member and a hollow seal portion that is integrally formed on the base portion and seals between the divided roof panels. The base portion and the hollow seal portion are formed by extrusion molding. They can be integrally formed at the same time and are easy to manufacture.

  The hollow seal portion is a hollow seal that is continuous between the pair of hollow seal portion side walls extending from the front and rear of the base portion and the other end of the pair of hollow seal portion side walls, and abuts between the sliding roof panel and another roof panel. Consists of upper wall. For this reason, when the sliding roof panel is closed, a gap between the sliding roof panel and another roof panel can be sealed with the upper wall of the hollow seal portion. At this time, the side walls of the pair of hollow seal portions can be elastically bent, and the upper wall of the hollow seal portion can be elastically pressed into the gap to be sealed.

  At least one hollow seal part side wall of the pair of hollow seal part side walls is bent. For this reason, when the upper wall of the hollow seal portion is pushed by high-pressure water during high-pressure car washing or the like, the side wall of the hollow seal portion having a bent portion is bent, and the upper wall of the hollow seal portion is bent downward together with the side wall of the hollow seal portion. The high pressure water flows in the direction of the base of the sliding roof panel weather strip, which is the direction away from the sliding roof panel. Therefore, the high-pressure water does not directly hit between the sliding roof panel and the sliding roof panel weather strip, and does not enter between them, thereby preventing entry into the vehicle.

  According to a second aspect of the present invention, the roof panel divided into a plurality of parts in the front-rear direction of the vehicle body comprises a transparent member divided into three parts. The first roof panel is a sliding roof panel that is tilted up at the rear, the second roof panel is tilted up and slides backward, and the third roof panel is fixedly attached to the vehicle roof and is weather stripped. Comprises a front weather strip that seals between the first roof panel and the second roof panel, and a rear weather strip that seals between the second roof panel and the third roof panel.

Since the roof panel is composed of a first roof panel, a second roof panel, and a third roof panel from the front side and is divided into three parts, the size of each roof panel is larger than a non-divided sliding roof panel. The roof panel can be made small, and mounting of each roof panel becomes easy.
Since the rear portion of the first roof panel is tilted up, it is possible to prevent a large amount of air from flowing into the vehicle interior by controlling the flow of air when the sliding roof panel is opened.

Since only the second roof panel is a sliding roof panel that tilts up and slides backward, it is possible to simplify the sliding mechanism with a single sliding roof panel, contributing to a reduction in vehicle weight. it can.
Since the third roof panel is fixedly attached to the vehicle body roof, it is possible to maintain daylighting and a feeling of opening while reducing the opening portion of the vehicle body roof opening while leaving the transparent portion as it is. In addition, the third roof panel is attached with a simple structure because there is no moving part, and can contribute to weight reduction and cost reduction.

  The weather strip includes a front weather strip that seals between the first roof panel and the second roof panel, and a rear weather strip that seals between the second roof panel and the third roof panel. The hollow seal part of the strip 20 and the hollow seal part of the rear weather strip are respectively attached so as to seal between the panels. For this reason, when the second roof panel is closed by sliding the second roof panel, which is a sliding roof panel, the rear end of the first roof panel and the front end of the third roof panel are elastically contacted, The gap can be sealed.

Consists of an upper wall of a hollow seal portion that is continuous between the other ends of the seal portion side wall and seals between the movable member and the other panel member, and at least one of the pair of hollow seal portion side walls is formed by bending, One weather strip is a sealing structure for automobiles, and is disposed inside a movable member or another panel member substantially in parallel with a second weather strip.

  In the present invention of claim 7, the plurality of panel members divided in the front-rear direction of the vehicle body are attached to the vehicle body opening of the automobile, at least one of the panel members is a movable member, and between the movable member and the other panel member. This is a seal structure for sealing with a weather strip. Since the space between the movable member and the other panel member is sealed by the weather strip, the space between the panel members can be reliably sealed even if the panel member is divided.

  The vehicle body opening is provided with a base member that is located inside the plurality of panel members and attaches a weather strip. For this reason, the weather strip includes a base portion attached to the base member and a hollow seal portion that is integrally formed on the base portion and seals between the divided panel members. It can be integrally formed at the same time by extrusion and is easy to manufacture.

  The weather strip has a first weather strip comprising a mounting base and a hollow seal portion formed integrally on the mounting base, and a second weather strip comprising a mounting base and a hollow seal portion. The hollow seal portion of the second weather strip is continuous between the other ends of the pair of hollow seal portion side walls extending from the front and rear of the attachment base portion, and seals between the movable member and the other panel member. Consists of upper wall. For this reason, when a panel member closes, the clearance gap between a panel member and another panel member can be sealed with a hollow seal part upper wall. At this time, the side walls of the pair of hollow seal portions can be elastically bent, and the upper wall of the hollow seal portion can be elastically pressed into the gap to be sealed.

  At least one of the side walls of the pair of hollow seal portions is formed by bending, and the first weather strip is disposed inside the movable member or other panel member substantially in parallel with the second weather strip. For this reason, when the upper wall of the hollow seal portion is pushed by high-pressure water during high-pressure car washing or the like, the side wall of the hollow seal portion having a bent portion is bent, and the upper wall of the hollow seal portion is bent downward together with the side wall of the hollow seal portion. The high-pressure water flows in the direction of the base of the second weather strip, which is the direction away from the panel member. Therefore, the high-pressure water does not directly hit between the panel member and the second weather strip, and does not enter between them, so that entry into the vehicle can be prevented.

It is sectional drawing of a wide part in the front-back direction.

FIG. 3 is a plan view of the roof panel 10 divided into three parts. The roof panel 10 includes a first roof panel 11, a second roof panel 12, and a third roof panel 13 from the front side. The rear portion of the first roof panel 11 is tilted up and down with the front end as the center. The second roof panel 12 is a sliding roof panel 12 that tilts up and down as a whole and slides in the front-rear direction of the vehicle. The third roof panel 13 is fixedly attached to the base member 3 in the present embodiment.
The upper surface of an annular weather strip (sliding roof panel weather strip) 40 is in contact with the lower surface of the sliding roof panel 12 as the second roof panel 12 so as to surround the outer peripheral end portion in an annular shape. A front weather strip 20 is disposed between the first roof panel 11 and the second roof panel 12, and a rear weather strip 30 is disposed between the second roof panel 12 and the third roof panel 13. Yes.

FIG. 4 is a perspective view seen obliquely from above, showing a state in which the first roof panel 11, the second roof panel 12, and the third roof panel 13 of the roof panel 10 divided into three are positioned with respect to the base member 3. is there.
The base member 3 has two opening portions corresponding to the divided roof panel 10 and is attached to the vehicle body roof opening portion 2.
The base member 3 is provided with an outer frame 3a on the outer periphery, and an intermediate frame 3b is provided between an opening corresponding to the second roof panel 12 and an opening corresponding to the third roof panel 13, and the outer frame 3a. It is linked with.
5 to 6 are diagrams showing the configuration and movement of the front weather strip 20, the rear weather strip 30, the annular weather strip 40, the base member 3 to which these weather strips are attached, and the roof panel 10. It is.

First, the shape of the front weather strip 20 will be described with reference to FIGS. As will be described later, since the rear weather strip 30 has substantially the same shape as the front weather strip 20, the description will be made centering on the front weather strip 20.
The front weather strip 20 is formed by extrusion, has a substantially straight shape, and is continuous in the longitudinal direction. The cross section of the front weather strip 20 includes a base 21 attached to the base member 3 and a hollow seal portion 26 that is integrally formed on the base 21 and seals between the divided roof panels 10.

The base 21 has a substantially trapezoidal cross section, a hollow base 25 having a hollow interior, a base bottom wall 22 forming a trapezoidal base, base sides 23 and 24 forming a trapezoidal hypotenuse, and a trapezoidal shape. It is formed from a base upper wall 24 that forms the upper side. The base hollow portion 25 increases the flexibility of the base portion 21 so that it can be mounted along the base member 3 to reduce the weight.
Bottom protrusions 22 a and 22 a are provided on the lower surface of the base bottom wall 22. A double-sided adhesive tape 20 b is attached to the lower surface of the base bottom wall 22 and is fixedly bonded to the base member 3. At this time, the bottom protrusions 22 a and 22 a can be pressed against the base member 3 to provide a seal between the base 21 and the base member 3. Similarly, the double-sided adhesive tape 20b can also seal between the base 21 and the base member 3.

The hollow seal portion 26 is formed in a sector fan shape in the front and rear direction (front side and rear side) of the base portion upper wall 24 of the base portion 21, that is, upward from the upper surfaces of both side ends in the width direction.
The hollow seal portion 26 is integrally formed in a circular arc shape by connecting a pair of hollow seal portion side walls 27, 27 formed in an inverted C shape from the front and rear of the base upper wall 24 and the tips of the hollow seal portion side walls 27, 27. It is formed of a hollow seal portion upper wall 28 that is curved toward the upper direction and a hollow hollow seal portion hollow portion 29 inside the hollow seal portion 26.

  When the sliding roof panel 12 is closed, the sliding roof panel 12 is first slid obliquely from above, and its tip abuts against the hollow seal portion 26 and tilts down from above to push the hollow seal portion 26. At this time, the hollow seal portion upper wall 28 of the hollow seal portion 24 contacts and seals the gap between the rear end of the first roof panel 11 and the sliding roof panel 12 (second roof panel). At this time, since the hollow seal portion upper wall 28 is curved in an arc shape toward the upper direction, even if the gap varies, the gap can be reliably sealed.

  Next, as shown in FIG. 2, the annular weather strip 40 will be described, and the flow of high-pressure water during high-pressure car washing will be described. An upper surface of an annular annular weather strip 40 that is a sliding roof panel weather strip is brought into contact with the lower surface of the end portion of the sliding roof panel 12 over the entire circumference. The annular weather strip 40 is mounted on the lower surface of the end portion of the sliding roof panel 12 so that the hollow seal portion 43 abuts slightly inside the portion where the hollow seal portion 26 of the front weather strip 20 abuts. Yes. For this reason, the front weather strip 20 and the annular weather strip 40 can double seal.

The annular weather strip 40 includes a linear extruded portion formed by extrusion molding and a molded portion in which the linear portions are connected by molding. The annular weather strip 40 is formed in an annular shape and has a peripheral edge portion of the sliding roof panel 12. Seals against the lower surface. As shown in FIG. 2, the annular weather strip 40 has a base 41 attached to the base member 3 and a hollow that is integrally formed on the base 41 and abuts against the lower surface of the sliding roof panel 12 for sealing. It consists of a seal part 43.
In the present embodiment, the annular weather strip 40 is formed in an annular shape. However, it is sufficient that the sliding roof panel 12 can be double-sealed, and a linear weather strip is combined as the sliding roof panel weather strip. May be used.

  The base 41 has a substantially flat cross section, and bottom convex portions 42 and 42 are provided on the lower surfaces of both side ends in the width direction. A clip 46 and a double-sided adhesive tape 45 are attached to the lower surface of the base 41, and the clip 46 is inserted and locked in an attachment hole provided in the base member 3, and the double-sided adhesive tape 45 is adhesively fixed to the base member 3. At this time, the bottom protrusions 42, 42 can be pressed against the base member 3 to seal between the base 41 and the base member 3. Further, since the double-sided adhesive tape 45 is attached to the front end side of the sliding roof panel 12 relative to the clip 46, that is, to the outer peripheral side, rainwater entering from the gap between the roof panels 10 is formed between the base 21 and the base member 3. It is possible to seal entry from the inside and entry into the vehicle compartment from the mounting hole of the clip 46.

  The hollow seal portion 43 is formed in a hollow arc shape upward from the upper surface of both side ends of the base portion 41 in the width direction. When the sliding roof panel 12 slides so as to close the vehicle body roof opening 2 and then tilts down, the hollow seal portion 43 comes into contact with the lower surface of the sliding roof panel 12 to seal the vehicle roof opening 2. .

  In the present embodiment, as shown in FIG. 2, the base bottom wall 22 of the front weather strip 20 and the base 41 of the annular weather strip 40 are integrally connected by a connecting portion 60. Therefore, as will be described later, the high-pressure water that has entered the hollow seal portion 26 of the front weather strip 20 has entered the base portion 21 of the front weather strip 20, the base portion 41 of the annular weather strip 40, and the base member 3. The connecting portion 60 that is integrally continuous along the surface forms a discharge path having a substantially U-shaped cross section, and is discharged outside the vehicle. Since both base parts 21 and 41 are integrally continuous, there is no gap and high-pressure water does not leak.

  Next, the flow of high-pressure water during high-pressure car washing will be described. When high-pressure water from the high-pressure car wash is sprayed between the rear end of the first roof panel 11 and the front end of the sliding roof panel 12, as shown by the dotted line in FIG. The hollow seal portion 26 is pushed downward. At this time, since the hollow seal portion side wall 27 on the annular weather strip 40 side is bent from the base side wall 23, it is easily bent at the bent portion, and the hollow seal portion upper wall 28 is inclined downward. Deform. As a result, the high-pressure water flows in the direction of the base portion 41 of the annular weather strip 40 along the hollow seal portion upper wall 28.

Therefore, the high-pressure water stops vigorously near the bases of the base part 41 and the hollow seal part 43, and does not enter between the hollow seal part 43 and the sliding roof panel 12, thereby reliably preventing entry into the vehicle. Can do.
