Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a seal structure for a collapsible pillar provided in, for example, a so-called open-top automobile in which the upper rear portion of the vehicle body is covered with a hood that can be opened and closed.

(Conventional technology) Feeling of freedom when driving in warm, sunny weather;
In order to improve the feeling of exhilaration and enjoy a comfortable drive, a car has been put into practical use in which the roof panel is removed and the hood with a rear window can be folded and stored at the rear of the car body. Ori,
As this type of car, for example, the British published patent No.
There is one shown in Publication No. 2086316.

This type of car is called an open-top car, and has an inverted U-shaped retractable pillar at the rear of the car, which can be rotated to the front of the car to raise it up, allowing the hood to be placed in a position that covers the upper part of the rear of the car. and also
By rotating the collapsible pillar toward the rear of the vehicle body, the hood is stored at the rear of the vehicle body.

(Problem to be solved by the invention) By the way, in a car equipped with this type of collapsible pillar, when the collapsible pillar is rotated forward and the hood is moved to a position that covers the rear of the vehicle body. , ensuring sealing between the hood and the vehicle body and the mating surface between the lower surface of both legs of the collapsible pillar and the vehicle body facing the lower surface to prevent the intrusion of rainwater when driving in the rain and the intrusion of car wash liquid when washing the car. It is requested to prevent this.

For this purpose, a sealing material is provided on the lower surface of both legs of the collapsible pillar and the surface facing the vehicle body. The material is pressed into contact with the material to ensure a seal on the facing surface and prevent rainwater, car wash fluid, etc. from entering.

However, with the above-mentioned structure in which the lower surfaces of the legs come into contact with the vehicle body when the collapsible pillar is rotated forward from the rearward state, it is difficult to properly align the contact parts. For example, if there is an assembly error between the collapsible pillar and the vehicle body, the sealing material on the collapsible pillar side will be misaligned with the sealing material on the vehicle body side due to this error, and as a result, the alignment The sealing performance on the surface decreases. In particular, such problems are more likely to occur as the distance from the center of rotation of the collapsible pillar to the mating surface of the sealing material is shorter, that is, the radius of rotation of the collapsible pillar is smaller.
It is conceivable to increase this distance to reduce the displacement of the sealing material, but doing so would cause problems such as a decrease in the rigidity of the collapsible pillar.

The present invention addresses the above-mentioned situation in automobiles equipped with retractable pillars, and improves the sealing material provided on the lower surface of both legs of the retractable pillar and the vehicle body facing the surface. Even if a positional shift occurs between sealing materials due to an assembly error of an inverted pillar, the purpose is to effectively absorb this positional shift and ensure required sealing performance.

(Means for Solving the Problems) That is, in the present invention, an inverted U-shaped retractable pillar is disposed at the rear of the vehicle body, and the pillar is retracted into a first position where it stands up almost vertically and at the rear side of the vehicle body. In an automobile configured to be rotated between a second position and a second position, a sealing material is provided on the lower surface of both legs of the collapsible pillar and on the vehicle body facing the lower surface, and at least one of these sealing materials is provided. The first collapsible pillar
It is characterized by a seal lip that extends forward and backward and is provided in a protruding manner so as to come into pressure contact with the other seal member when in position.

(Function) According to the above configuration, when the collapsible pillar is properly assembled to the vehicle body, the sealing material provided on the lower surface of both legs of the collapsible pillar and the vehicle body opposite to the lower surface. The mating surfaces are in close contact with each other to ensure the required sealing performance, and even if a positional shift occurs between the two sealing materials when the pillar is erected due to an assembly error of the collapsible pillar, Since the seal lip provided on at least one seal material comes into pressure contact with the other seal material, the required sealing performance is ensured.
