Abstract

PURPOSE:To aim at reduction in sliding resistance and keep off the occurrence of a step difference between both weather strips as well as to prevent rainwater from penetrating, by installing a pack of water-repellent planted bristles in an end of either a body side weather strip or a center weather strip or both. CONSTITUTION:A body side weather strip 4 is attached along a front pillar 11 via a retainer and its end part is slightly projected to an opening part for a sun roof. And, an end face of the strip 4, closing a hollow part, is molded into a baglike form and its upper half part is tilted endwise and the lower half part upward respectively, and on the surface, there is provided with a pack of water- repellent planted bristles 16. Therefore, occurrence of any clearance between both is completely prevented owing to these fine planted bristles 16 and simultaneously with the water-rellence, the penetration of rainwater along the contact surface is preventable without fall.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a T-bar roof vehicle in which both sides of the vehicle body roof are provided with removable sunroofs.
This invention relates to an improvement in the seal structure for jIkK.

BACKGROUND ART FIG. 2 shows a T-bar roof vehicle with removable sunroofs 2 on both sides of the vehicle roof 1. In this case, the structure is such that the roof sight rails are removed from the vehicle body. Weather sealing the edge of the door glass 3
The strip is separated at the sunroof 2 portion to form a round shape. That is, body side weather strings 4 are fixed to the front and rear edges of the door opening on the vehicle body side to seal the front and rear edges of the door glass 3, and the side edges of the sunroof 2 are fixed to the door glass. A center weather strip 5 is fixed to seal the upper edge of the weather strip 3, and the end surfaces of the two are brought into contact with each other so as to be continuous.

FIG. 3 shows the installation state of the center weather strip 5, where 6 is a glass, 7 is a finisher fixed to the back side of the strip, 8 is a center molding, and 9 is a garnish.

The center weather strip 5 has a hollow structure as shown in the figure, and the body side weather strip 4 also has approximately the same cross-sectional shape as this, but the end faces that abut each other have a hollow structure. is formed by closing the hollow part, and as shown in Fig. 2,
The body side weather strip 147 is slightly protruded, and the center weather strip 5t is slightly retreated.

are doing. Since the sunroof 2 is attached to the vehicle body from above, the end face of each weather strip is made into an inclined surface in the lower half, as shown in Fig. 4, and is pushed in from above. The sloped surface of the center weather strip 5 is shaped so that the sloped surface of the body side weatherstrip 4 is received, so that a good close contact can be obtained between the two (for example, Nichiwa Motors, 1939).

Problems to be Solved by the Invention However, in the above-mentioned seal structure, the end surfaces of the weather strips 4 and 5 made of rubber are directly abutted against each other. When pushed in from above as shown by the arrow in Figure 4, the sliding resistance at the contact surface is extremely large, causing the tip of the body side weather strip 4 to slide downward and downward as shown by the imaginary line in Figure 4. If there is a difference in level between the center weather strip 5 and the body side weather strip 4, the sealing performance against the edge of the door glass 3 and the sunroof 2 and the vehicle body side may be affected. This may deteriorate the sealing performance between the body side weatherstrip 4 and cause rainwater to enter.Matomo, in order to prevent the deformation of the body side weatherstrip 4 mentioned above, the pressure contact condition of the end face of each weatherstrip was set loosely. If so, it is easy to cause rainwater to enter.

Elaborate Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides water-repellent flocking on one or both end surfaces of the body side weather strip and center weather strip IJ knob. This flocking reduces sliding resistance, prevents the occurrence of a level difference between the IJ knobs (when a sunroof is installed), and prevents rainwater from entering the contact surface between the two. It is.

Embodiment FIG. 1 shows, as an example, a body side weather strip 4 attached to the front edge of a door opening on the vehicle body side. This body side weather strip 4 has approximately the same cross-sectional shape as the center weather strip 5 shown in FIG. Moreover, the end portion slightly protrudes into the sunroof opening. 12 is a drip part surrounding the sunroof opening on three sides; 13 is a sunroof weather strip attached along the inner circumference of the drip part 12; 14 is a sunroof weather strip that closes the end of the drip part [2]; The dam part 5 is inserted into the pin fitting hole for fixing the sunroof 2, and the sunroof weather strip 13 has its ends widened to form the ends of the body side weather strip 4. connected to the inner surface of the

The end face of the body side weather strip 4 is formed into a bag shape by closing the hollow part, and as described above, the upper half is substantially vertical and the lower half is slightly inclined upward. , water-repellent flocking 16 is provided on its surface.

The flocked hair 16 is obtained by planting hairs of nylon or the like on the surface of a base material coated with an adhesive by an electrostatic flocking method, and then applying a water repellent treatment using a silicone resin. Here, the silicone resin used for this water repellent treatment is made of an organosiloxane composition containing silicon atoms, and has the property of curing at room temperature or under heating, and when applied to other substances. It exhibits excellent water repellency, WI4 weatherability 2 abrasion resistance, and has the characteristics of being able to significantly reduce sliding resistance and obtain good sliding properties.

Although not shown, the end face of the center weather strip 5 which is brought into contact with the end face of the upper body side weather strip 4 is provided with similar flocks.

Therefore, when the center weather strip 5 is pushed into the body side weather strip 4 from above when the sunroof 2 is installed, extremely good sliding properties are exhibited between the end surfaces that come into pressure contact with each other due to the intervention of the flocks 16. (Body side weather) I) The tip of knob 4 does not fall downward. The fine flocked flocks 16 completely prevent the formation of gaps between the two, and their water repellency also reliably prevents rainwater from entering along the contact surface.

Effects of the Invention As is clear from the above explanation, in the seal structure for a T-bar roof vehicle according to the present invention, the body side weather
There is no difference in level between the strip and the center weather strip, and the sealing performance against the edge of the door glass can be demonstrated stably, and rainwater can be reliably prevented from entering the contact surface of each edge. Watertightness is greatly improved compared to the conventional structure.
