Abstract

PURPOSE:To prevent seal cut due to the draft of a door glass by having a weather strip of a car with a sashless door provided with an inside seal portion applied in contact with the upper-end inside face of the door glass and an energizing means so as to allow the inside seal portion to be pressively moved to a car body outside. CONSTITUTION:An upward lip-like inside seal portion 6c is provided on a car body inside further than the upper-end seal portion 6b of a sashless door glass 5 so as to be applied in contact with the upper-end inside face of the door glass 5. Additionally, an energizing means 11c, which moves the inside seal portion 6c following movement of the door glass 5 to the car body outside, is provided on the back of the inside seal portion 6b. The inside seal portion 6c is thus kept in the state of being applied in contact with the upper-end inside face of the door glass 5, resulting in no need to provide a restricting member for the draft prevention of the door glass and no detraction of aerodynamic characteristic of a car.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a weather strip for a sashless door.

(Prior Art) Vehicles having a satsuri-less door in which the edge of the door glass is brought into contact with a weather strip disposed around the opening of the vehicle body are generally known. For this vehicle,
Since there is no saturation on the door glass, the door glass is sucked out to the outside of the vehicle during high-speed driving when the outside of the vehicle is under negative pressure.
The seal may break between the door glass and the weather strip, causing noise from the air being sucked out of the vehicle interior.
This makes it easier for rainwater etc. to enter the vehicle interior.

On the other hand, there has been a proposal to prevent the door glass from being sucked out by providing a stopper member on the periphery of the opening of the vehicle body that contacts the door glass from the outside of the vehicle. For example, Japanese Utility Model Application Publication No. 57-55614 discloses a weatherstrip in which a hard guide member is provided in contact with the upper end of the door glass from the outside of the vehicle.

(Problem to be Solved by the Invention) However, in the case of the conventional means of providing a regulating member on the outside of the vehicle to prevent the door glass from being sucked out, the portion of the vehicle where the regulating member is provided protrudes slightly to the outside of the vehicle body. This poses a problem in that it not only adversely affects the aerodynamic characteristics during driving, but also affects the appearance of the vehicle.

(Means for Solving the Problems) In order to solve these problems, the present invention does not take the conventional idea of regulating the suction of the door glass, but solves the problem caused by this suction, that is, the relationship between the door glass and the weather strip. This was done based on the discovery that the suction itself is not a problem if the broken seal between the windows can be solved, and a part of the weather strip is pushed to the outside of the vehicle body to follow the suction of the door glass. and
This prevents the seal from breaking and eliminates the need for a regulating member on the outside of the vehicle body.

That is, the weatherstrip for a dustless door according to the present invention is provided in a vehicle having a dustless door in which the edge of the door glass is brought into contact with the weatherstrip disposed around the opening of the vehicle body. The vehicle is provided with an inner seal portion that comes into contact with the inner surface of the upper end of the door glass, and a biasing means that urges the inner seal portion to follow the movement of the door glass toward the outside of the vehicle body and push the inner seal portion toward the outside of the vehicle body. It is characterized by:

(Function) In the case of the weather strip for a satsuri-less door, even if the door glass is sucked out to the outside of the vehicle body when the vehicle is running at high speed, the biasing means causes the inner seal portion to follow the door glass and push it to the outside of the vehicle body. This will prevent the seal from breaking between the door glass and the weather strip.

(Effects of the Invention) Therefore, according to the present invention, there is no need to provide a regulating member for preventing the door glass from being drawn out on the outside of the vehicle. It can solve the problem of cutting.

(Example) Embodiments of the present invention will be described below based on the drawings.

Example 1- This example is illustrated in FIGS. 1-3.

In a vehicle 1 shown in FIG. 1, 2 is a door provided in an opening 4 of a vehicle body 3. As shown in FIG. This door 2 is a sashless door in which the edge of the door glass 5 directly contacts a weather strip, which will be described later, provided around the periphery of the opening 4.

FIG. 2 specifically shows the structure of the weather strip 6. As shown in FIG. That is, in the figure, 7 is a roof panel, 8 is a rain rail, 9 is an inner roof rail, and 10 is an outer roof rail, and the retainer 11 of the weather strip 6 is attached to the outer roof rail 10, as also shown in FIG. It is fixed to the base of the molding 12 with a screw 13 through the base of the molding 12. Also, between the retainer 11 and the base of the molding 12, and this molding 1
Cushion materials 14 and 15 are interposed between the base portions of the roof rails 2 and the roof rail outer 10, respectively.

The weather strip 6 includes a base portion 6a that is fitted and bonded to one of the mating recesses of the retainer 11, an upper end seal portion 6b that comes into contact with the upper edge of the door glass 5, and the upper end seal portion 6b.
It is provided with an upwardly directed lip-shaped inner seal portion 6C that is provided on the inner side of the vehicle body and comes into contact with the inner surface of the upper end portion of the door glass 5.

On the other hand, the retainer 11 is an outer member 11 located outside the vehicle body.
a, and an inner member 11b located inside the vehicle body,
Both members 11a and 11b are joined together by partially overlapping each other. The inner member 11b is made of a shape memory alloy, and comes into contact with the back of the inner seal portion 6C of the weather strip 6, that is, the side surface of the weather strip 6 inside the vehicle body, so as to close the inner seal portion 6C on the outside of the vehicle body. It is provided with a biasing portion 11C that can be pushed.

That is, when the inner member 11b is heated, the biasing portion 11c moves as shown by the chain line in FIG. 2 (the inner seal portion 6
C is deformed to a position where it is pushed to the outside of the vehicle body, and at room temperature, it is deformed to the inside of the vehicle body as shown by the solid line in the same figure, and the above-mentioned pushing is released.

As a heating means for this inner member 11b, the above-mentioned urging section 1
At the base of the retainer 1c, a heating element 16 is provided in the longitudinal direction of the retainer 11, as shown in FIG. This heating element 16 is used when the vehicle is running at high speed (for example, when the vehicle is running at high speed).
The vehicle speed switch 17, which is opened upon detecting a speed of 100 m or more, receives electricity from a power source 18.

Therefore, in the case of the vehicle 1 described above, when the vehicle is stopped or normally running, the vehicle speed switch 17 is open, the heating element 16 is not energized, and the biasing portion 11c of the retainer 11 is in the state shown by the solid line in FIG. Therefore, the inner seal portion 6c of the weather strip 6 is not pushed toward the outside of the vehicle body. Therefore, the door glass 5 is not subjected to any force from the inner seal portion 6C toward the outside of the vehicle body, so it can easily come into contact with the upper end seal portion 6b of the weather strip 6, and there is no problem in closing the door 2. Of course, there is no problem in raising and lowering the door glass 5.

Therefore, when the vehicle 1 is running at high speed, the outside of the vehicle body becomes a negative pressure compared to the inside of the vehicle body due to the running wind, and the door glass 5 is slightly sucked out to the outside of the vehicle body as shown by the chain line in FIG. When the vehicle speed switch 17 is opened, the heating element 16 is energized and generates heat, and the inner member 11b of the retainer 11 is heated and its biasing portion 11c is deformed toward the outside of the vehicle body as shown by the chain line in FIG. Therefore, the inner seal portion 6c of the weather strip 6 is pushed toward the outside of the vehicle body following the suction of the door glass 5 by the urging of the urging portion 11c, and comes into contact with the inner surface of the upper end of the door glass 5. Therefore, the seal between the door glass 5 and the weather strip 6 does not break. In other words, no noise is generated due to air being sucked out of the vehicle interior, and no rainwater or the like enters the vehicle interior.

In the above embodiment, the beam taker 11 is divided into the outer and inner members 11a and llb, but the entire retainer 11 may be integrally formed of a shape memory alloy.

Embodiment 2 - This embodiment is shown in FIGS. 4 and 5, and differs from the previous embodiment in the biasing means for the inner seal portion 6c of the weather strip 6.

That is, in the weather strip 6 of this example, an elastic tube 6d is disposed at the back along the inner seal portion 6c. This tube 6d has one end connected to a water tank 21 via an electric pump 22, and the other end is closed. The electric pump 22 is activated by receiving electricity from a power source 18 by a vehicle speed switch 17 that is opened when the vehicle is running at high speed. 6
d, and when the operation is stopped, the water in the tube 6d can be returned to the water tank 21. Note that the other configurations are the same as in the first embodiment.

Therefore, in the case of this example, when the vehicle is running at high speed, the tube 6d of the weather strip 6 is supplied with water and expands.
The inner seal portion 6c is pushed toward the outside of the vehicle body following the suction of the door glass 5, thereby preventing the seal from breaking.

Note that a liquid other than water or a gas such as air may be supplied to the tube 6d.
