[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved weatherstrip for a sashless type or convertible type vehicle.

[0002]

2. Description of the Related Art Conventionally, as a sashless type weather strip, as shown in FIG. 1, a drip molding or a hood 50 is suspended from an outdoor end of a body opening edge portion 10 which is inclined upward and outward. A base portion 31 is fitted to the opening edge portion 10 via a retainer 20, and a hollow seal portion 32 elastically contacting the upper end and the inner surface of the closed door glass 40 is integrally connected to the base portion 31. On the outside of the base 31, a drip molding or a hood 50 is provided with a swing stopper 33 for stopping the swing of the door glass 40 while being backed up.

Conventionally, as a weather strip of a convertible type vehicle, as shown in FIG. 2, although slightly different in shape from FIG. 1, a drip molding is provided at an outdoor end of a body opening edge 10 which is inclined outward. Alternatively, a hood 50 is vertically provided, a base 31 is fitted to the body opening edge 10 via a retainer 20, and a hollow seal elastically contacts the upper end and the inner surface of the closed door glass 40 to the base 31. The part 32 is integrally connected.

However, the conventional sashless type weather strip 30 has a small wrap amount (overlap width) C between the steady rest portion 33 and the drip molding 50 and the door glass 40 when viewed from the path of entry of the door glass 40, There is a problem that, due to the variation of the drip molding 50 and the like, the waterproofness is reduced, and the effect of preventing the door glass 40 from being sucked out during running at high speed is reduced.

Further, the conventional weatherstrip 30 of a convertible type vehicle has a problem that a gap A exists between the door glass 40 and a hood (not shown), and the wind noise during traveling is high. Further, the wrap amount (overlap width) C between the drip molding 50 and the door glass 40 is small, and the waterproofness is low, as in the sashless type weather strip 30, and the effect of preventing the door glass 40 from being sucked out at the time of high-speed running is low. There is also a problem.

[0006]

The problem to be solved is that the conventional weatherstrip has a low waterproof property due to the variation of the drip molding 50 or the like, or the door glass 40 is sucked out at the time of high-speed running. This is because the effect of prevention is low, or there is a gap A between the door glass 40 and the hood (not shown), and the wind noise during traveling is high.

[0007]

A description will be given with reference to FIGS. 3 and 4. FIG. In the present invention, a drip molding 50 is suspended from the outdoor end of the body opening edge 10 inclined upward and the base 31 is fitted to the body opening edge 10 via a retainer 20. Closed door glass 4 on base 31
0 is a weather strip formed by integrally connecting a hollow seal portion 32 made of sponge rubber and elastically contacting an upper end and an inner surface of the hollow seal portion. A leg portion 36 made of solid rubber and extending along the inner surface of the drip molding 50 is continuously formed at the outdoor end of the portion 31, and protrudes from the distal end thereof to both the outside and the inside of the room. The small lip-shaped glass run portion 37 is joined, and the retainer 20
A sub-retainer 21 extends along the outer surface of the leg portion 36 at the outdoor end of the sub-retainer 21 so as to cover the end of the sub-retainer 21 outside the small lip-shaped glass run portion 37 and to meet the drip molding 50. It covers the gap, and seals the outer surface of the door glass 40 on the indoor side of the small lip-shaped glass run portion 37.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the embodiment will be described. Reference numeral 10 denotes a body opening edge which is inclined upward and 50 denotes a drip molding or a hood which is vertically provided at an outdoor end of the body opening edge 10. The length is set so that the lap amount (overlap width) C with the closed door glass 40 is sufficiently large. Reference numeral 30 denotes a weatherstrip for fitting the base 31 to the body opening edge 10 via the retainer 20. The weatherstrip 30 is configured in detail as follows. 31 is a base made of solid rubber, 32 is a closed door glass 4
A hollow seal portion elastically contacting the upper end and the inner surface of
It is integrally connected to the base 31 and is made of sponge rubber. A substantially horizontal bridge 35 is provided at an intermediate height. Reference numeral 36 denotes a leg extending from the outdoor end of the base 31 along the inner surface of the drip molding or the hood 50, and the tip of the leg 36 projects to both the indoor side and the outdoor side. The small lip-shaped glass run portion 37 is connected. Reference numeral 21 denotes a sub-retainer extending from the outdoor end of the retainer 20 along the outer surface of the leg 36. In summary, the weatherstrip of the present invention is:
It can be said that the hollow seal part of a general sponge and the solid glass run part are integrated. still,
The base 31 may be solid rubber or sponge rubber.

The operation will be described below. In the sashless type, the weather strip and the glass run are formed integrally. When the door is closed with the door glass 40 raised, first, the door glass 40 Along L, it first comes into contact with the lower part D of the hollow seal part 32, but after a few seconds, it jumps up to the upper part E, and the door glass 40
Is completely closed, that is, a so-called dropping glass type. At that time, the lap amount (overlap width) C between the door glass 40 and the hood 50 is sufficiently large as compared with the conventional one, and after being backed up, Door glass 40
Since the upper end and the inner surface of the cover are in close contact with the hollow seal portion 32, it is possible to completely prevent intrusion of water from outside and suction of the door glass 40 during high-speed traveling.

In a convertible vehicle, the same effect as described above is exhibited, and a gap A between the hood 50 of the hood (not shown) and the door glass 40 is provided with a small lip-shaped glass run portion 37 connected to the tip of the leg portion 36. , The wind noise is extremely low even at high speeds.

[0011]

[Effect of the Invention] Since the present invention is configured as described above,
It is possible to completely prevent intrusion of water from the outside and suction of the door glass 40 at the time of high-speed running, and to significantly reduce wind noise at the time of high-speed running.

Further, rainwater or the like is applied to the hollow seal portion 32 and the leg portion 3.
Even if the water enters between the two, the water is passed from between the two, for example, between the base 31 and the retainer 20, and enters the room. In addition, the legs 36 provide excellent waterproofness.
