DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weatherstrip for a sashless door type vehicle which is attached to an opening of a vehicle body and seals the interior and exterior of the vehicle.

[0002]

2. Description of the Related Art As such a weather strip, a weather strip having a structure as shown in FIGS. This weather strip is composed of a base portion 3 attached to the vehicle body opening 1 via a retainer 2 and a hollow lip 4 connected to the base portion 3. Stay 5 and 6 to increase reaction force
Is provided. And the sealing wall 7 of the hollow lip 4
Outside R _o is formed by bulging direction, or close the door 9 in a state of increasing the door glass 8, by or raise the door glass 8 with the door closed 9, the outer periphery of the door glass 8 When the portion is pressed against the seal wall 7, the seal wall 7 is elastically deformed and comes into close contact with the outer peripheral edge of the door glass 8. In the drawing, 10 denotes a car wash hose, R _i denote the vehicle.

[0003] This similar structure is disclosed in JP-A-63-41233.
It is shown in Japanese Patent Publication No.

[0004]

However, in the case of the conventional weather strip shown in FIGS. 4 and 5, since the sealing wall 7 of the hollow lip 4 has substantially the same thickness over the entire cross section, When the inside corner C on the outer periphery of the door glass 8 comes into close contact with the seal wall 7, A of the seal wall 7 in FIG.
(A portion located further on the outer peripheral side than the outer peripheral end surface of the door glass 8) is crushed, and the opening angle θ formed by the outer peripheral end surface of the door glass 8 and the seal wall 7 becomes large, and strong water discharge during car washing etc. At this time, water droplets may enter the vehicle interior from this portion. That is, when the opening angle θ increases, the water pressure applied to the contact portion between the door glass 8 and the seal wall 7 at the time of strong water discharge increases, and water droplets enter the vehicle cabin from the gap between the seal wall 7 and the door glass 8 deformed by the water pressure. Increases the possibility of intrusion.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a sashless door type weather strip which can surely prevent water droplets from entering into a vehicle cabin during strong water discharge.

According to the present invention, as a means for solving the above-mentioned problem, a hollow lip is continuously provided on a base portion attached to an opening of a vehicle body, and a seal wall of the hollow lip is formed so as to protrude outwardly of the vehicle. In a weatherstrip of a sashless door type vehicle in which the outer peripheral portion of the door glass on the vehicle interior is in close contact with the seal wall, the outer peripheral portion of the door glass on the vehicle inner side of the seal wall is in close contact with the seal wall .
Area and the inner side of the area are formed to a substantially constant thickness
In the part of the outer periphery of the door glass where the inside corner of the door abuts, a thinner part having a locally thinner wall thickness than other parts is provided, and further on the outer peripheral side than the outermost end surface of the highest raised door glass. A high-rigidity portion was provided at the position where the member was located.

[0007]

When the outer edge of the door glass inside the vehicle abuts against the sealing wall of the hollow lip, the sealing wall is elastically deformed by the pressing force from the door glass.
The part where the peripheral edge is in close contact with the part on the inner peripheral side
With a constant thickness, the inside corner of the door glass abuts
Thin part is provided locally at the part where
The outer edge of the outermost edge of the door glass
Because the part located on the side is a high rigidity part, the seal wall is
In the state where the highest raised door glass is in contact,
As a bending point, almost at the corner inside the car around the door glass
Deforms to follow. Therefore, the opening angle between the outer peripheral end face of the door glass and the seal wall is extremely small.

[0008]

Next, an embodiment of the present invention will be described with reference to FIGS. The same parts as those shown in FIGS. 4 and 5 are denoted by the same reference numerals.

FIGS. 1 and 2 are sectional views corresponding to FIG. 5 of a weather strip according to the present invention, and FIG.
FIG. 2 shows a state in which the door glass 8 is not pressed.

In FIGS. 1 and 2, reference numeral 3 denotes a base portion which is attached to a vehicle body opening via a retainer, and a hollow lip 4 is extended from the base portion 3. The outside _Ro side of the hollow lip 4 is a sealing wall 7 for directly sealing the door glass 8. The sealing wall 7 is such that the connecting portion 11 with the base portion 3 bulges in a set amount outside the vehicle _Ro direction. It is formed. A stay 5 is formed inside the hollow lip 4 so as to connect the base portion 3 and the sealing wall 7, and the stay 5 causes the hollow lip 4 to have a sealing reaction force.

Further, a portion of the seal wall 7 at which the vehicle interior corner C on the outer periphery of the door glass 8 abuts, that is, the inner peripheral side of the vehicle opening slightly below the connecting portion 11 (the lower side in the figure).
Is formed in a thin portion 12 locally thinner than other portions, and when the door glass 8 abuts, the sealing wall 7 is centered on the thin portion 12. And easily bends and deforms. In addition, of the seal wall 7,
The area where the outer edge of the door glass 8 is in close contact with the vehicle interior
The portion on the inner peripheral side is formed to have a substantially constant thickness.
In addition, a portion of the seal wall 7 that is located on the outer peripheral side further than the outer peripheral end surface of the door glass 8 that has risen up, that is,
The connecting portion 11 is a high-rigidity portion that is provided with a support column 13 for reinforcement and is unlikely to be flexed and deformed by an external force.

The connecting portion 14 between the seal wall 7 and the stay 5
Is set as far as possible on the outer peripheral side of the vehicle body opening (upper side in the figure), thereby increasing the sealing reaction force of the sealing wall 7.

In the above configuration, when the door is closed with the door glass 8 raised to the highest position, or when the door glass 8 is raised with the door closed, as shown in FIG.
The inside corner C of the outer periphery of the door glass 8 contacts the thin portion 12 of the seal wall 7 , and at this time, the thin thickness of the seal wall 7 is reduced.
The rigidity of the part 12 is locally low and the door glass 8
The inner peripheral edge and the outer peripheral end face are
A constant thickness portion on the inner peripheral side of the thin portion 12 and the thin portion 12
And sufficient sealing reaction forces F ₁ , F ₂
From the outer peripheral edge of the door glass 5 and the outer peripheral end face.
Are securely in contact with the seal wall 7.

At this time, since the rigidity of the connecting portion 11 of the seal wall 7 is increased by the support column 13, the door glass 8
The thin portion 12 and its vicinity are bent and deformed along the outer peripheral end surface of the door glass 8 even when receiving the pressing force from the door glass 8. As a result, the outer peripheral end face of the door glass 8 and the seal wall 7 are almost in close contact with each other, and the opening angle θ of the slightly generated gap becomes extremely small. For this reason, the door glass 8
The problem that water drops intrude from the gap between the outer peripheral end face and the seal wall 7 does not occur.

In the embodiment described above, the strut 13 is provided to the connecting portion 11 as a means for providing a high rigidity portion on the seal wall 7. However, as shown in FIG. By increasing the thickness of 11, a highly rigid portion may be provided on the seal wall.

[0016]

As described above, according to the present invention, in the seal wall of the hollow lip, the outer peripheral edge of the door glass on the vehicle interior is in close contact.
The part to be formed and the part on the inner circumference side are formed with a substantially constant thickness.
In the area where the inside corner of the door glass comes into contact with the inside corner, a thin part is provided that is locally thinner than the other parts, and is further on the outer peripheral side than the outermost end face of the highest raised door glass. A high-rigidity part is provided at the position where the seal glass is in contact with the seal wall.
Since the opening angle between the outer peripheral surface of the door glass and the seal wall is made extremely small as a curved point so as to substantially conform to the outer peripheral surface of the door glass, the outer peripheral surface of the door glass and the seal wall are strongly disengaged during strong water discharge. The water pressure received in the gaps is reduced, and it is possible to reliably prevent water droplets from entering the vehicle interior. Ma
