SUMMARY OF THE INVENTION

In a roof of an automobile having an opening portion that includes a movable panel that can be opened and closed and a fixed panel, as compared with a vehicle having no movable panel that can be opened and closed in the roof, an interior height, which is one of indices indicating a space in the vehicle, that is, a vertical maximum distance from a flat floor surface near a center portion of the vehicle to a ceiling lining is shortened by about 10 mm to 30 mm. Therefore, it has been reported that some people, especially tall people are dissatisfied with small head clearance.

Further, in electric vehicles (EVs), which have been rapidly expanding in recent years, a battery is often mounted under a floor, which means that the floor surface is located upward, and a seat surface is also moved upward accordingly, so that the head clearance of a passenger is further reduced. Therefore, in a vehicle having a movable panel that can be opened and closed in the roof, narrowness of the head clearance may be a significant problem.

Further, from a viewpoint of weight reduction of the vehicle, it is also important to use resin for the panel and to reduce the size of an attachment portion of the roof weather strip. Furthermore, in a case where the roof weather strip is attached to a resin panel by adhesion, degreasing treatment or primer processing of the surface of the resin panel is required, and workability during assembly is poor. Further, in the case of the double-sided adhesive tape, water leakage due to peeling from the panel or the roof weather strip due to deterioration of the tape, and panel malfunction due to peeling of the roof weather strip also become problems.

According to a first disclosed aspect includes, an attachment structure for a roof weather strip, in whichat least two panels are disposed on a roof of a vehicle,a first panel is a movable panel configured to be able to open and close an opening portion of the roof, a second panel is a fixed panel that is made of resin and fixedly disposed adjacent to a vehicle front side or a vehicle rear side of the first panel, an inclined surface having an acute angle is formed at a second panel end portion of the second panel on a side of the first panel in a vehicle downward direction from the side of the first panel in a vehicle vertical direction, a weather strip attachment portion having a substantially L-shaped cross section is formed in the vehicle downward direction from a second panel lower surface of the second panel and in the direction of the first panel, the roof weather strip includes an attachment base having a substantially U-shaped cross section and a hollow seal portion connected to the attachment base, and the attachment base is attached to the weather strip attachment portion.

According to the first disclosed aspect, the weather strip attachment portion having a substantially L-shaped cross section is formed in the vehicle downward direction from the second panel lower surface of the second panel and in the direction of the first panel, the roof weather strip includes the attachment base having a substantially U-shaped cross section and the hollow seal portion connected to the attachment base, and the attachment base is attached to the weather strip attachment portion, therefore, the workability during attachment is improved as compared with a case where the roof weather strip is attached by adhesion, and defects such as water leakage due to deterioration after attachment due to adhesion and peeling of the roof weather strip can be eliminated.

Further, since the weather strip attachment portion has a substantially L-shaped cross section in the vehicle downward direction from the second panel lower surface of the second panel and in the direction of the first panel, the attachment base of the roof weather strip can be located higher in the vehicle as compared with a case where the weather strip attachment portion is formed perpendicular to the second panel. As a result, the interior height can be increased in a vehicle having an opening portion in the roof that includes a movable panel that can be opened and closed and a fixed panel.

Further, since the inclined surface having an acute angle is formed at the second panel end portion of the second panel on the side of the first panel in the vehicle downward direction from the side of the first panel in the vehicle vertical direction, the hollow seal portion can be disposed including a space in the vehicle downward direction of the inclined surface. As a result, when the hollow seal portion is brought into contact with the first panel, the hollow seal portion can be deformed without generating a load such as excessive bending. Further, since the space in the vehicle downward direction of the inclined surface is used, a space between the first panel and the second panel can be narrowed. Furthermore, it is possible to easily perform control for preventing the hollow seal portion from protruding upward from the vehicle between the first panel and the second panel and impairing an appearance of the roof.

Here, the “movable panel” refers to a panel that is movable in a front-rear direction of the vehicle so as to be able to open and close an opening portion formed in the roof of the vehicle. Further, the “fixed panel” refers to a panel that is attached to the roof of the vehicle and does not move in the front-rear direction of the vehicle. Note that, the fixed panel includes an operation in which the side of the movable panel of the fixed panel moves upward of the vehicle when the movable panel opens the opening portion.

According to a second disclosed aspect includes, an attachment structure for a roof weather strip, in which a protruding portion is formed in the weather strip attachment portion, an engagement portion is formed inside an opening of the attachment base, and the protruding portion and the engagement portion are engaged with each other.

According to the second disclosed aspect, the protruding portion is formed in the weather strip attachment portion, the engagement portion is formed inside the opening of the attachment base, and the protruding portion and the engagement portion are engaged with each other, therefore, even when a force in the front-rear direction of the vehicle is applied to the attachment base due to deformation of the hollow seal portion when the first panel is opened and closed, the attachment base can be prevented from moving in the front-rear direction of the vehicle.

Incidentally, although the first panel can be opened and closed, a time period during which the first panel is left in a closed state, that is, in a state where the hollow seal portion and the end portion of the first panel are in contact with each other, is generally long. Therefore, there is a case where the hollow seal portion and the end portion of the first panel are fixed to each other, and when the first panel is opened in a state where the hollow seal portion and the end portion of the first panel are fixed to each other, the hollow seal portion is pulled in the front-rear direction of the vehicle, and accordingly, the attachment base connected to the hollow seal portion is also pulled in the front-rear direction, and there is a possibility that the attachment base comes off from the weather strip attachment portion.

Even in this case, since the protruding portion and the engagement portion are engaged with each other, even when the hollow seal portion is pulled in the front-rear direction of the vehicle, and the attachment base connected to the hollow seal portion is pulled in the front-rear direction, it is possible to prevent the attachment base from coming off from the weather strip attachment portion.

According to a third disclosed aspect includes, an attachment structure for a roof weather strip in which at least one of an upper bulging portion and a lower bulging portion is formed on a side surface on a non-opening side of the attachment base, hardness of the upper bulging portion and the lower bulging portion is lower than that of a member constituting the attachment base, the upper bulging portion is in contact with the second panel lower surface, and the lower bulging portion is in contact with a housing disposed in the vehicle downward direction of the second panel.

According to the third disclosed aspect, at least one of the upper bulging portion and the lower bulging portion is formed on the side surface on the non-opening side of the attachment base, the hardness of the upper bulging portion and the lower bulging portion is lower than that of the member constituting the attachment base, the upper bulging portion is in contact with the second panel lower surface, and the lower bulging portion is in contact with a housing disposed in the vehicle downward direction of the second panel, therefore, the upper bulging portion bends when it comes into contact with the second panel lower surface, and a space between the attachment base and the second panel lower surface is sealed, so that it is possible to prevent water from entering. Further, the upper bulging portion serves as a downward biasing force, which can stabilize an attachment position of the roof weather strip and reliably fix the attachment base of the roof weather strip to the weather strip attachment portion. Further, even when the attachment base deteriorates over time, it is possible to prevent the distal end portion on an opening side of the attachment base having a substantially U-shaped cross section from expanding and the attachment base from being easily detached from the weather strip attachment portion.

On the other hand, the lower bulging portion bends when it comes into contact with the housing, a space between the attachment base and the housing is sealed, and when the first panel, being a movable panel, is opened, water adhering to the hollow seal portion can be prevented from entering the attachment base and the housing in a case where the water flows downward on the surface of the hollow seal portion or in a case where the water bounces back at a lower position.

Note that, in the third disclosed aspect, since at least one of the upper bulging portion and the lower bulging portion is formed on the side surface on the non-opening side of the attachment base, a case where only the upper bulging portion is formed, a case where only the lower bulging portion is formed and a case where both the upper bulging portion and the lower bulging portion are formed are included.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

An embodiment of the present invention will be described with reference toFIGS.1to3. Note that, hereinafter, the front-rear direction of a vehicle1is referred to as a “front-rear direction”, and an upper side and a lower side in a height direction of the vehicle1are referred to as an “upper side” and a “lower side”, respectively. Further, a width direction of the vehicle1is referred to as a “width direction”.

FIG.1is a plan view of a roof2of the vehicle1as viewed from above the roof2. The vehicle1is a sedan type automobile, the roof2is divided into four by panels in the front-rear direction, a first panel11is a movable panel, and a second panel12, a third panel13, and a fourth panel14are fixed panels, which is a type called a so-called panoramic roof (panoramic moonroof). The first panel11and the third panel13are made of a glass plate, and by moving a cover of the glass plate on a vehicle interior side, it is possible to enhance a sense of openness inside the vehicle in a wide area and to take light into the vehicle. Note that, the vehicle1is not limited to a sedan type automobile, and the roof2is not limited to a panoramic roof type.

The first panel11is attached so as to be able to open and close an opening portion10. In other words, the first panel11is attached so as to be capable of performing a tilt-up operation in which its rear portion is raised with its front portion as a fulcrum and a sliding operation in the front-rear direction. In an opening/closing operation by the first panel11, a so-called outer sliding type in which the first panel11slides while remaining in a tilted-up state is adopted. In the first panel11, a first panel edge portion11a(FIG.3) that has a substantially quadrangular annular shape made of a polyurethane resin material along periphery of the first panel11and corresponds to an end portion on the side of the second panel12is formed. Note that, the resin material of first panel edge portion11ais not limited to polyurethane.

On the other hand, the second panel12is located in front of the first panel11and is attached so as to block a front portion of the opening portion10. The second panel12is configured so that when the first panel11moves rearward, the first panel11side thereof is lifted upward in order to adjust entrance of wind into the vehicle. Note that, the second panel12may have a configuration in which the first panel11side thereof is not lifted upward.

FIG.2is a cross-sectional view of a roof weather strip20. The roof weather strip20has an attachment base21and a hollow seal portion22connected to the attachment base21. The attachment base21has a substantially U-shaped cross section in which a first vertical side portion23and a second vertical side portion24are connected by a coupling portion25.

An upper bulging portion28is formed in a semicircular shape on an outer side surface of the first vertical side portion23of the attachment base21(a side surface of the first vertical side portion23that is not on the side of an opening26(non-opening side)). Note that, the shape of the upper bulging portion28is not limited to a semicircular shape. The upper bulging portion28is formed of a material having hardness lower than that of a member constituting the first vertical side portion23.

A lower bulging portion29is formed in a semicircular shape on an outer side surface of the second vertical side portion24of the attachment base21(a side surface of the second vertical side portion24that is not on the side of the opening26(non-opening side)). Note that, the shape of the lower bulging portion29is not limited to a semicircular shape. The lower bulging portion29is formed of a material having hardness lower than that of the member constituting the second vertical side portion24.

An engagement portion27is formed inside the opening26of the attachment base21and on an inner side surface of the second vertical side portion24(a side surface of the second vertical side portion24on the side of the opening26). The engagement portion27has a substantially right-angled triangular shape in which a degree of protrusion from the inner side surface of the second vertical side portion24decreases as the distance from the coupling portion25increases. Note that, an oblique side of the substantially right-angled triangle may have an arc shape.

The hollow seal portion22is connected to the attachment base21at a first end portion30and a second end portion31, which are two end portions, and has a substantially D-shaped cross section. The first end portion30is connected to a position across the first vertical side portion23and the coupling portion25, and the second end portion31is connected to the coupling portion25. Note that, the connection portion between the first end portion30and the second end portion31with the attachment base21is not limited to the above position.

The roof weather strip20is formed by extrusion molding such that the cross section inFIG.2is continuously formed in the width direction inFIG.1. Ethylene propylene diene rubber (EPDM) was used as a material of the roof weather strip20, a solid material was used for the attachment base21, and a sponge material was used for the hollow seal portion22, the upper bulging portion28, and the lower bulging portion29. The hardness of the solid material is an international rubber hardness degree (IRHD) of 60 or more. Further, the hollow seal portion22has a specific gravity of 0.4 or more and 1.0 or less. In the present embodiment, sponge materials having the same hardness were used for the hollow seal portion22, the upper bulging portion28, and the lower bulging portion29. Note that, it is preferable that the hardness of the upper bulging portion28and the lower bulging portion29is less than or equal to the hardness of the hollow seal portion22from a viewpoint of ease of bending in contact with a second panel lower surface12b(FIG.3) in the upper bulging portion28and in contact with a housing50(FIG.3) in the lower bulging portion29.

FIG.3is a cross-sectional view taken along an A-A line inFIG.1when the roof weather strip20according to the embodiment of the present invention is attached to the second panel12and the first panel11is closed. The second panel12is made of resin. In the second panel12, an inclined surface16having an acute angle X is formed at a second panel end portion15on the side of the first panel11in a downward direction from the side of the first panel11. Further, an angle formed by a first panel upper surface11band a first panel side surface11cof the first panel edge portion11ais 100 degrees. Note that, the angle formed by the first panel upper surface11band the first panel side surface11cis not limited to 100 degrees.

Further, a weather strip attachment portion17having a substantially L-shaped cross section is formed downward from the second panel lower surface12bof the second panel12and in the direction of the first panel11. The weather strip attachment portion17in a substantially L-shaped shape includes a projecting portion17athat projects substantially vertically downward from the second panel lower surface12b, and a mounting portion17bthat extends substantially parallel to the second panel lower surface12bfrom a lower distal end portion of the projecting portion17a, and a protruding portion18that protrudes downward and engages with the engagement portion27formed in the attachment base21of the roof weather strip20is formed at the distal end portion of the mounting portion17bon the side of the first panel11. Note that, the upper bulging portion28is formed in a semicircular shape on the outer side surface of the first vertical side portion23of the attachment base21, and since the upper bulging portion28bends and comes into contact with the second panel lower surface12bof the second panel12, in order to engage the engagement portion27formed on the second vertical side portion24with the protruding portion18, it is necessary to open the second vertical side portion24on the side of the opening26to allow the protruding portion18to pass through. Therefore, it is preferable that the protruding portion18is formed on a lower side of the mounting portion17b.

Further, when the protruding portion18and the engagement portion27are engaged with each other, the attachment base21can be stably attached to the mounting portion17bwhen the protruding portion18matches the shape of the joined portion between the second vertical side portion24and the coupling portion25, therefore, it is preferable that the protruding portion18is formed in a rectangular shape, in particular, a rectangular shape or a square shape at the distal end portion of the mounting portion17b.

It is preferable that the distal end portion of the mounting portion17bon the side of the first panel11is formed so that when the attachment base21of the roof weather strip20is attached to the mounting portion17b, the outer side surface (the surface on the non-opening side) of the coupling portion25of the attachment base21is near a connection portion19between the second panel lower surface12band the inclined surface16with a vertical downward direction interposed therebetween because the hollow seal portion22can be disposed by effectively utilizing the inclined surface16. InFIG.3, the outer side surface of the coupling portion25of the attachment base21is located slightly closer to the side of the first panel11than the vertical downward direction (a dashed-dotted line) of the connection portion19.

In the present embodiment, the angle X between a second panel upper surface12aand the inclined surface16is 50 degrees. Note that, the angle X between the second panel upper surface12aand the inclined surface16is preferably 40 degrees to 60 degrees. In a case where the angle X is less than 40 degrees, although the length of the inclined surface16can be secured, it is necessary to form the hollow seal portion22large in the front-rear direction, and the weight of the roof weather strip20increases, which is not preferable. Further, when the angle X exceeds 60 degrees, the space between the inclined surface16and the first panel edge portion11abecomes narrow, and accordingly, when the first panel11is closed, the degree of curvature of an upper end portion22aduring deformation increases in the hollow seal portion22, and durability of the hollow seal portion22decreases, which is not preferable.

When the upper bulging portion28is attached to the mounting portion17bof the weather strip attachment portion17from the opening side of the attachment base21of the roof weather strip20, above the mounting portion17b, the upper bulging portion bends and comes into contact with the first vertical side portion23of the attachment base21and the second panel lower surface12b, and seals between the first vertical side portion23and the second panel lower surface12b.

Further, below the mounting portion17b, the protruding portion18formed on the mounting portion17band the engagement portion27formed on the second vertical side portion24of the attachment base21are engaged with each other. Since the engagement portion27has a substantially right-angled triangular shape in which the degree of protrusion of the second vertical side portion24from the side surface decreases as the distance from the coupling portion25increases, the attachment base21is easily inserted into the mounting portion17bforward from the side of the first panel11.

A housing40is disposed below the second panel12. In the housing40, a housing step portion41with a step on the lower side is formed on the side of the first panel11. Further, the distal end portion of the housing step portion41is bent by 90 degrees with respect to the housing step portion41and extends downward.

When the housing40is disposed, the lower bulging portion29bends below the mounting portion17band comes in contact with the housing step portion41to seal between the second vertical side portion24and the housing step portion41.

When the first panel11is closed, the hollow seal portion22of the roof weather strip20is pressed against the first panel edge portion11aof the first panel11and deforms, and the hollow seal portion22comes in contact with the first panel edge portion11aof the first panel11and the inclined surface16of the second panel12.

Further, the upper end portion22aof the hollow seal portion22is located below a line connecting the first panel upper surface11band the second panel upper surface12a.

As described above in detail, according to the present embodiment, the following effects can be obtained.

(1) In the present embodiment, the roof weather strip20includes the attachment base21having a substantially U-shaped cross section and the hollow seal portion22connected to the attachment base21, and the attachment base21is attached to the weather strip attachment portion17formed in the housing50, therefore, the workability during attachment is improved as compared with attachment by adhesion of the roof weather strip20, and defects associated with deterioration after attachment due to adhesion can be eliminated.

(2) In the present embodiment, since the hollow seal portion22is in contact with the first panel edge portion11aof the first panel11and the inclined surface16of the second panel12, it is possible to prevent water from entering the vehicle interior side from between the first panel11and the second panel12.

(3) In the present embodiment, the weather strip attachment portion17has a substantially L-shaped cross section downward from the second panel lower surface12bof the second panel12and in the direction of the first panel11, and the weather strip attachment portion17in a substantially L-shaped shape includes the projecting portion17athat projects substantially vertically downward from the second panel lower surface12band the mounting portion17bthat extends substantially parallel to the second panel lower surface12bfrom the lower distal end portion of the projecting portion17a, and the attachment base21of the roof weather strip20is attached to the mounting portion17bthat extends substantially parallel to the second panel lower surface12b, therefore, the attachment base21of the roof weather strip20can be located higher in the vehicle as compared with a case where the weather strip attachment portion17is formed perpendicular to the second panel12. As a result, the interior height can be increased in a vehicle having an opening portion in the roof that includes a movable panel that can be opened and closed and a fixed panel.

(4) In the present embodiment, since the inclined surface16having an acute angle is formed at the second panel end portion15of the second panel12on the side of the first panel11in the downward direction from the side of the first panel11in the vertical direction, the hollow seal portion22can be disposed including a space formed below the inclined surface16. As a result, when the hollow seal portion22is brought into contact with the first panel11, the hollow seal portion22can be deformed without generating a load such as excessive bending. Further, since the space below the inclined surface16is used, the space between the first panel11and the second panel12can be narrowed. Furthermore, it is possible to easily perform control for preventing the upper end portion22aof the hollow seal portion22from protruding upward from between the first panel11and the second panel12and impairing the appearance of the roof.

(5) In the present embodiment, the protruding portion18that protrudes downward in a rectangular shape is formed at the distal end portion of the mounting portion17bof the weather strip attachment portion17on the side of the first panel11, the engagement portion27having a substantially right-angled triangular shape in which the degree of protrusion from the side surface of the second vertical side portion24decreases as the distance from the coupling portion25increases is formed on the inner side surface of the second vertical side portion24of the attachment base21of the roof weather strip20, and the protruding portion18and the engagement portion27are engaged with each other, therefore, it is easy to insert the attachment base21on which the engagement portion27is formed into the mounting portion17bof the weather strip attachment portion17on which the protruding portion18is formed.

Further, after the attachment base21is attached to the mounting portion17b, even when a force in the front-rear direction of the vehicle1is applied to the attachment base21due to the deformation of the hollow seal portion22when the first panel11is opened and closed, the attachment base21can be prevented from moving in the front-rear direction of the vehicle1.

Further, in general, a time period during which the first panel11is left in a closed state, that is, in a state where the hollow seal portion22and the first panel edge portion11aare in contact with each other is generally long, and there is a case where the hollow seal portion22and the first panel edge portion11aof the first panel11are fixed to each other, however, even in this case, since the protruding portion18and the engagement portion27are engaged with each other, even when the hollow seal portion22is pulled in a backward direction of the vehicle1, and the attachment base21connected to the hollow seal portion22is pulled in the backward direction, it is possible to prevent the attachment base21from coming off from the weather strip attachment portion17.

(6) In the present embodiment, the upper bulging portion28is formed on the outer side surface of the first vertical side portion23of the attachment base21, the hardness of the upper bulging portion28is lower than that of the member constituting the attachment base21, and the upper bulging portion28bends, deforms, and is in contact with the second panel lower surface12b, therefore, the side of the first vertical side portion23of the attachment base21is biased against the weather strip attachment portion17, whereby the attachment position of the roof weather strip20is stabilized.

Further, when the first panel11is opened, the upper bulging portion28is in contact with the second panel lower surface12beven when water accumulated in a contact portion between the hollow seal portion22and the inclined surface16or water adhering to the hollow seal portion22flows to the inclined surface16or the side of the inclined surface16of the hollow seal portion22, therefore, it is possible to prevent the flowing water from entering between the attachment base21and the weather strip attachment portion17.

Further, even when the hollow seal portion22deteriorates over time and water enters between the hollow seal portion22and the inclined surface16, it is possible to prevent water from entering between the attachment base21and the weather strip attachment portion17.

(7) In the present embodiment, the lower bulging portion29is formed on the outer side surface of the second vertical side portion24of the attachment base21, and even when the housing40is disposed below the second panel12, the hardness of the lower bulging portion29is lower than that of the member constituting the attachment base21, and the lower bulging portion29bends, deforms and is in contact with the housing step portion41of the housing40, therefore, the side of the second vertical side portion24of the attachment base21is biased against the weather strip attachment portion17, whereby the engagement between the engagement portion27and the protruding portion18can be reliably secured. Further, the attachment position of the roof weather strip20is stabilized.

Further, when the first panel11is opened, the lower bulging portion29is in contact with the housing step portion41even when the water accumulated in the contact portion between the hollow seal portion22and the first panel edge portion11aor the water adhering to the hollow seal portion22flows along the side of the first panel11of the hollow seal portion22or when the water flowing along the side of the first panel11drops and bounces back at a lower position, therefore, it is possible to prevent the flowing water or bounced water from entering between the attachment base21and the housing40.

(8) In the present embodiment, since the second panel12is made of resin, weight reduction can be achieved.

The implementation of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention.

The roof weather strip20may be made of a thermoplastic elastomer, a soft synthetic resin, or the like in addition to EPDM. As the thermoplastic elastomer, in addition to TPV, an olefinic thermoplastic elastomer (TPO) is preferable from the viewpoints of weather resistance, recycling, cost, and the like.
