DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash-equipped door car sealing structure for sealing between a sash-equipped door and a body panel by a door weatherstrip.

[0002]

2. Description of the Related Art As shown in FIGS. 1 to 4, a door weather strip 3 is attached to a door 1 of a door car with a sash. 2 is an enlarged cross section taken along line AA of FIG. 1, FIG. 3 is an enlarged cross section taken along line BB of FIG. 1, and FIG. 4 is an enlarged cross section taken along line CC of FIG. A door weather strip 3 is attached to the door 1 along the periphery of the door sash 2 above the belt line BL and the door periphery below the belt line BL.

The door weather strip 3 includes a mounting base 4 to be mounted on a door frame, a hollow seal portion 5 integrally formed with the mounting base 4 and having a hollow cross section, and a hollow portion located outside the hollow seal portion 5 on the vehicle interior side. A seal lip portion 6 having a lip-shaped (tongue-shaped) cross section integrally formed with the seal portion 5 is provided. One extruded door weatherstrip 3 is formed by molding at a rear upper corner portion. They are connected integrally. Above the belt line BL, when the door 1 is closed, the hollow seal portion 5
The seal lip 6 located on the peripheral edge of the door sash 2 in parallel with the hollow seal portion 5 also elastically contacts the body panel 20.

[0004]

However, as shown in FIGS. 2 to 4, at the rear side of the door 1 below the belt line BL, when the door is closed, only the hollow seal portion 5 elastically contacts the body panel 20. It has a seal structure. That is, the rear side of the door portion of the sash-equipped door has a structure in which the belt line portion from the base of the sash abruptly projects in the width and rearward directions (see the attached drawings). Has also become. Therefore, the sealing function by the weather strip requires a double seal at the sash part with no thickness, the door part is overhanged in the width and the rear, so the seal part is deeper than the parting part, and even a single seal is supported You can do it. However, a smooth shape change is desirable on the body side of a portion where the belt line portion changes rapidly in consideration of press formability. As a result, in the part that changes rapidly,
In addition, the seal lip portion 6 does not elastically contact, and the original sealing function is not exhibited.

For this reason, there is a case where the high-pressure water W from a car wash or the like directly hits the hollow seal portion 5 without coming into contact with the body panel 20 and the seal lip portion 6 as shown in the locus shown in FIG. In such a case, there is a possibility that the hollow seal portion 5 loses the water pressure and the water leaks.

In order to prevent this, a hollow seal portion 5 is provided for stabilizing the door weather strip 3 against pressure.
In order to increase rigidity by putting a pad in the inside or to fix the mounting base 4 using butyl tape. Further, as shown in FIGS. 3 and 4, the shape of the surface of the body panel 20 is further reduced from the state shown in FIG. 2 below the belt line BL to the lower part corresponding to the place where the high-pressure water W enters. Since the high-pressure water W changes so as not to directly hit the hollow seal portion 5, the mold forming portion is set between the lower part of the belt line BL and the limit position of the direct hit of the hollow seal portion 5 shown in FIG. However, there is a problem that the sealing performance is improved and the door tightness is deteriorated and the cost is increased, although the effect is somewhat improved.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a sash-equipped door car seal structure which enhances the sealing property between the rear side of the sash-equipped door and the body panel without increasing the cost by adding other members. To provide.

[0008]

In order to achieve the above object, a seal structure for a door car with a sash according to the first aspect of the present invention comprises a door sash (2) above a belt line (BL) of the door car with a sash. A door weatherstrip (3) integrally formed with a hollow seal portion (5) and a seal lip portion (6) is attached along a peripheral edge and a door peripheral portion below the belt line (BL). When the door is closed, the hollow seal portion ( 5)
And a seal structure of a door car with a sash in which a seal lip portion (6) located at the periphery of the door sash (2) is in elastic contact with the body panel (20). (20) surface (20A)
When the door is closed, the rear side of the door (1) and the body panel (20) do not come into contact with the surfaces of the seal lip (6) and the body panel (20) at least when the door is closed. When the door is closed, the position of the body panel (20) changes from a position where it can reach the hollow seal portion (5) in a straight line via the parting-off portion (M) to a position where the shape of the surface of the body panel (20) changes. It is characterized in that it is provided so as to be continuously pressed against the seal lip (6).

[0009] The seal structure for a door car with a sash according to the second aspect of the present invention is the same as the first aspect of the invention.
The surface of the body panel (20) is continuously pressed against the back surface of the seal lip (6) on the side of the hollow seal portion (5).

The symbols in parentheses above correspond to the symbols described in the drawings and the embodiments of the invention described later.

According to the present invention, the periphery of the door sash at the upper portion of the belt line is double-sealed by the hollow sealing portion and the sealing lip portion of the door weather strip elastically contacting the body panel. And, on the rear side of the door below the belt line, the surface of the body panel facing the peripheral edge of the door is projected so as to be continuously pressed against the back surface of the seal lip portion on the side of the hollow seal portion when the door is closed. Therefore, the hollow seal portion and the seal lip portion are double-sealed by elastically contacting the surface of the protruding body panel, similarly to the door sash peripheral portion above the belt line.

Therefore, even if high-pressure water is applied by a car wash or the like, the hollow seal portion is not directly hit, and the pressure is relieved by contacting the body panel or the seal lip portion, so that the water flows through the hollow seal portion. Therefore, it is prevented from entering the vehicle interior. Furthermore, since the sealing lip portion elastically contacts the surface of the protruded body panel below the belt line, the fixing force of the mounting base of the door weather strip increases, so that water infiltrates into the vehicle interior through the mounting base. Is also prevented.

Moreover, the surface of the body panel protruded from the lower part of the belt line does not come into contact with the seal lip portion and the surface of the body panel from at least the outside of the vehicle compartment when the door is closed. It is sufficient if the shape of the surface of the body panel changes from a position where it can reach the hollow seal portion in a straight line through the parting line to a position where it cannot be reached. Since there is no need to extend the length, there is almost no effect on the press formability of the body panel, which is efficient.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A seal structure for a door car with a sash according to an embodiment of the present invention will be described with reference to FIG. FIG. 5 is an enlarged cross-sectional view taken along line AA of FIG. 1 showing a seal structure of a door car with a sash according to the embodiment of the present invention. The same parts as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

[0015] The seal structure of the door car with sash according to the embodiment of the present invention is similar to that shown in the conventional example, and the door sash 2 peripheral portion above the belt line BL and the door below the belt line BL of the door car with sash. Along with one peripheral edge, a door weather strip 3 is integrally mounted with a hollow seal portion 5 having a hollow cross section and a seal lip portion 6 having a lip cross section located outside the hollow seal portion 5 on the vehicle interior side, When the door is closed, the hollow seal part 5 and the door sash 2
The back surface of the seal lip portion 6 located on the peripheral edge on the side of the hollow seal portion 5 elastically contacts the body panel 20.

At the lower position of the belt line BL, the surface 20A of the body panel 20 facing the periphery of the door 1 at the rear side of the door 1 is continuously connected to the back surface of the seal lip portion 6 on the side of the hollow seal portion 5 when the door is closed. It is made to protrude so as to press against. As described above, in the present embodiment, when the door is closed, the body panel 2 is brought into contact with the side surface of the surface 20A of the body panel 20 in which the back surface of the seal lip portion 6 is projected.
The surface 20A of the 0 is protruded, but the projecting direction is not limited to this, and the gap between the hollow seal portion 5 and the seal lip portion 6 is covered by the surface 20A of the protruded body panel 20. Should be fine. In FIG. 5, the position of the body panel 20 before the projecting is indicated by a dotted line.

The surface 2 of the body panel 20 to be protruded here
In the range of 0A, the parting line M between the rear side of the door 1 and the surface of the body panel 20 from the lower position of the belt line BL without contacting the seal lip portion 6 and the surface of the body panel 20 from outside the vehicle compartment at least when the door is closed. Is set to a position where the shape of the surface of the body panel 20 changes from a position where the hollow seal portion 5 can be reached linearly through the limit position (a position shown in FIG. 3), and continuously during that range. And is pressed against the seal lip portion 6.

Below the limit position as shown in FIG. 4, even if the high water pressure W caused by the car washing or the like is applied to the parting portion M from outside the vehicle cabin, it does not directly hit the hollow seal portion 5 but before the body panel 20 This is because the water pressure is reduced by contact with the body panel 20, so that the surface of the body panel 20 need not be particularly protruded.

The seal lip portion 6 has a substantially U-shaped shape in which a substantially central portion is curved toward the hollow seal portion 5 (upward in FIG. 5), and a rear surface of a front end portion of the surface 20A of the body panel 20 is projected. It is an inner contact type that comes into contact with the side. Therefore, when the high-pressure water W from the car wash or the like is applied to the seal lip portion 6,
The force acts in a direction in which the substantially rectangular shape is further curved, and the force at which the distal end portion elastically contacts the body panel 20 increases, so that the sealing performance is further improved.

According to the sealing structure configured as described above, the hollow seal portion 5 and the seal lip portion 6 of the door weather strip 3 are joined to the body panel 20 at the periphery of the door sash 2 above the belt line BL as in the conventional example. The seal is double-sealed by elastic contact. And belt line B
A door weatherstrip 3 which is continuous from the periphery of the door sash 2 above the belt line BL and has a common cross section is attached to the periphery of the door 1 below L, and the surface 20A of the body panel 20 protrudes from the rear side. , Belt line BL
Similarly to the peripheral edge of the upper door sash 2, the hollow seal portion 5 and the seal lip portion 6 are double-sealed by elastically contacting the protruding surface 20A of the body panel 20.

Therefore, even when high-pressure water W is applied by a car wash or the like, the hollow seal portion 5 is not directly hit, and the pressure is relieved by contacting the body panel 20 or the seal lip portion 6. Intrusion into the vehicle interior through the hollow seal portion 5 is prevented. Further, the protruding body panel 20 below the belt line BL is provided.
When the seal lip portion 6 elastically contacts the surface 20A, the fixing force of the mounting base portion 4 of the door weather strip 3 is increased, so that the water W is prevented from entering the vehicle interior through the mounting base portion 4.

[0022]

As described above, according to the present invention, the periphery of the door sash above the belt line is double-sealed by the hollow seal portion and the seal lip portion of the door weather strip elastically contacting the body panel. Then, on the rear side of the door below the belt line, the hollow seal portion and the seal lip portion elastically contact with the protruding body panel surface in the same manner as the door sash peripheral portion above the belt line, so that it is doubled. Sealed.

Therefore, even if high-pressure water is applied by a car wash or the like, the hollow seal portion is not directly hit, and the pressure is reduced by abutting on the body panel or the seal lip portion, so that the water flows through the hollow seal portion. Therefore, it is prevented from entering the vehicle interior. Furthermore, since the sealing lip portion elastically contacts the surface of the protruded body panel below the belt line, the fixing force of the mounting base of the door weather strip increases, so that water infiltrates into the vehicle interior through the mounting base. Is also prevented.

In addition, since it is only necessary to project the surface of the body panel from the position below the belt line to a predetermined position, the effect on the press formability of the body panel is substantially negligible, and the pad and butyl tape are efficiently provided. There is no need to use a new member or to newly set a molded part, so that there is no particular increase in cost.
