BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for a sashless door type vehicle that is attached to an opening in a vehicle body to seal the interior and exterior of the vehicle.

0002

2. Description of the Related Art As this type of weather strip, one having a structure as shown in FIGS. 4 and 5 has been put into practical use. This weather strip consists of a base part 3 attached to a vehicle body opening 1 via a retainer 2, and a hollow lip 4 connected to the base part 3. Inside the hollow lip 4, there is a seal. Stays 5 and 6 to increase reaction force
is provided. and the sealing wall 7 of the hollow lip 4
is formed to bulge out in the direction of outside the vehicle Ro, and by closing the door 9 with the door glass 8 raised or raising the door glass 8 with the door 9 closed, the outer peripheral part of the door glass 8 can be expanded. When the seal wall 7 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 addition, in the figure, 10 indicates a car wash hose, and Ri indicates the interior of the vehicle.

[0003] This similar structure is disclosed in Japanese Patent Application Laid-Open No. 63-41233.
This is shown in the publication number, etc.

0004

[Problems to be Solved by the Invention] However, in the case of the conventional weather strip shown in FIGS. 4 and 5, the seal wall 7 of the hollow lip 4 has approximately the same thickness over the entire cross section; When the vehicle-inward corner C of 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.
The part shown in (the part located further to the outer periphery than the outer periphery of the door glass 8) is crushed, and the opening angle θ formed between the outer periphery of the door glass 8 and the seal wall 7 increases, resulting in strong water spray during car washing, etc. There is a risk that water droplets may sometimes enter the passenger compartment from this area. That is, as the opening angle θ increases, the water pressure applied to the contact area between the door glass 8 and the seal wall 7 increases during strong water discharge, and water droplets enter the passenger compartment from the gap between the seal wall 7 and the door glass 8, which are deformed by this water pressure. The possibility of infiltration increases.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a weather strip for a sashless door type vehicle that can reliably prevent water droplets from entering the vehicle interior during strong water spraying.

[0006]

[Means for Solving the Problems] As a means for solving the above-mentioned problems, the present invention includes a hollow lip that is connected to a base portion that is attached to an opening in the vehicle body, and a sealing wall of the hollow lip that extends outward from the vehicle. In a weather strip for a sashless door type vehicle, the outer peripheral edge of the door glass on the inside of the vehicle is in close contact with the seal wall, and the outer peripheral edge of the door glass is in close contact with the seal wall. A thin wall portion is provided at the portion where the inner corner comes into contact, and a high-rigidity portion is provided at a portion located further toward the outer periphery than the outer periphery end face of the door glass that is raised the highest.

[0007]

[Operation] When the outer circumferential edge of the door glass on the inside of the car comes into contact with the sealing wall of the hollow lip, the sealing wall deforms elastically under the pressure from the door glass, but the inner corner of the outer circumference of the door glass comes into contact with the sealing wall of the hollow lip. Since the contacting part is a thin part, and the part located further toward the outer periphery than the outer peripheral edge of the door glass is a highly rigid part, the part of the seal wall near the thin part almost follows the outer peripheral edge of the door glass. As a result, the opening angle between the outer peripheral end face of the door glass and the seal wall becomes extremely small.

[0008]

[Embodiment] Next, an embodiment of the present invention will be described based on FIGS. 1 and 2. Note that the same reference numerals are used for the same parts as those shown in FIGS. 4 and 5.

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

In FIGS. 1 and 2, reference numeral 3 denotes a base portion that is attached to an opening in the vehicle body via a retainer, and a hollow lip 4 is extended from the base portion 3. The outside Ro side of this hollow lip 4 is a sealing wall 7 that directly seals the door glass 8. This sealing wall 7 is formed by a connecting portion 11 with the base portion 3 bulging out by a set amount in the direction outside the vehicle Ro. has been done. A stay 5 is formed inside the hollow lip 4 so as to connect the base portion 3 and the seal wall 7, and the stay 5 gives the hollow lip 4 a sealing reaction force.

Furthermore, a portion of the seal wall 7 that is in contact with the inner corner C of the outer periphery of the door glass 8, that is, a portion slightly closer to the inner periphery of the vehicle body opening than the connecting portion 11 (lower side in the figure)
A thin wall portion 12 that is thinner than other portions is formed at the portion located at the seal wall 7, and the seal wall 7 easily bends and deforms around this thin wall portion 12 when the door glass 8 comes into contact with the door glass 8. It looks like this. Further, a portion of the seal wall 7 that is located further toward the outer circumferential side than the outer circumferential end surface of the door glass 8 that has risen the highest, that is, the connecting portion 11 is connected to the reinforcing column 1.
3 is provided across the body, making it a highly rigid part that is unlikely to be bent or deformed by external forces.

Note that the connecting portion 14 between the seal wall 7 and the stay 5
is set to be located as close to the outer periphery of the vehicle body opening (upper side in the figure) as possible, thereby increasing the seal reaction force of the seal wall 7.

In the above configuration, when the door is closed with the door glass 8 raised to the highest level, or when the door glass 8 is raised with the door closed, as shown in FIG.
A corner C of the outer periphery of the door glass 8 on the inside of the vehicle comes into contact with the thin part 12 of the seal wall 7, and the outer peripheral edge of the door glass 8 on the inside of the vehicle comes into close 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 pillar 13, the door glass 8
The thin wall portion 11 and its vicinity do not collapse and deform even when subjected to a pressing force from the door glass 8, but the thin wall portion 11 and its vicinity are bent and deformed along the outer peripheral end surface of the door glass 8. As a result, the outer peripheral end surface of the door glass 8 and the seal wall 7 are brought into substantially close contact with each other, and the opening angle θ of the slight gap formed is extremely small. For this reason, when strong water is released, the door glass 8
The problem of water droplets entering through the gap between the outer peripheral end face of the seal wall 7 and the seal wall 7 will no longer occur.

In the case of the embodiment described above, the support 13 was provided across the connecting portion 11 as a means for providing a highly rigid portion in the seal wall 7, but as shown in FIG. A high-rigidity portion may be provided in the seal wall by increasing the thickness of the seal wall 11.

[0016]

As described above, the present invention provides a thin wall portion in the sealing wall of the hollow lip at the portion where the inner corner of the outer periphery of the door glass comes into contact, and furthermore, the seal wall of the hollow lip is provided with a thin wall portion at the portion where the inner corner of the outer periphery of the door glass contacts. Furthermore, a high-rigidity part is provided at a part located on the outer peripheral side, so that when the door glass comes into contact with the seal wall, the part near the thin part of the seal wall is deformed so as to almost follow the outer peripheral end surface of the door glass. The opening angle between the outer edge of the door glass and the seal wall is made extremely small, so when strong water is sprayed, the water pressure applied in the gap between the outer edge of the door glass and the seal wall is reduced, ensuring that water droplets do not enter the passenger compartment. can be prevented.
