However, in the case of such a weatherstrip, the hollow seal portion 14 on the outside of the vehicle, to which the front door panel 1 is pressed, is directly supported between the windshield side molding 7 and the drip channel 6. Therefore, these variations in construction are absorbed by the bending of the hollow seal portion 14, and therefore, there is a possibility that the bending load becomes excessively high and the sealing performance is deteriorated.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a weather strip for a vehicle of the type described at the outset, which can avoid the influence of variations in the mounting structure.

[0005]

In order to achieve this object, according to the present invention, according to claim 1, a front end portion of a base portion has a molding base joined to a front pillar of a windshield side molding and a windshield peripheral portion. The rear end of the base is provided with a lip-shaped seal toward the outside of the cabin, and is engaged with a drip channel joined to the front pillar. A windshield side molding extending from a front pillar to a roof opening and having a hollow sealing portion toward the outside of the cabin near the front of the base portion. A locking piece that forms the intermediate surface along the bending direction of the hollow seal portion when the front door is closed, and locks the front end of the base at an intermediate position of the molding intermediate surface. A gap protruding rearward and allowing a displacement of the front end portion in the bending direction is formed closer to the base of the molding than the locking piece on the middle surface of the molding, and the front surface of the hollow seal portion is arranged in the vehicle compartment from the locking piece. Formed along the outer molding intermediate surface, and lower the front surface reaching the base from the middle position of the front surface so that a gap allowing displacement of the front surface in the bending direction is formed between the middle position and the locking piece. , Formed in an inverted L-shape.

The weather strip is supported by the drip channel at the rear end of the base, and the front end of the base is locked by a locking piece to position the hollow seal in the vehicle width direction. When the front door is closed, the front surface of the hollow seal part bends along the molding middle surface of the windshield side molding due to the gap on both sides of the locking piece, and the base part also displaces in the bending direction. Can also.

[0007]

FIG. 1 shows a weather strip for an automobile according to an embodiment of the present invention based on the body structure shown in FIG. 3, and the same or equivalent parts as those described above are denoted by the same reference numerals. Indicated by

The rear end of the base portion 21 of the weather strip 20 is provided with a lip-shaped seal portion 12 toward the outside of the vehicle in the same manner as described above, and the base portion 21 is attached to the locking piece 6a of the drip channel 6. Are engaged.

A hollow seal portion 24 is formed forward of the base portion 21 from an intermediate position in the vehicle longitudinal direction toward the outside of the vehicle. A molding intermediate surface 33 that is formed in front of the molding base 7a of the windshield side molding 30 is formed along the bending direction of the hollow seal portion 24 when the front door panel 1 is closed, that is, substantially along the vehicle width direction. The base 21 is located at an intermediate position of the surface 33 in the vehicle width direction.
Locking piece 35 for receiving and locking front end portion 12a of groove in groove 34
Are protrudingly provided toward the vehicle rear side.
That is, behind the front end 12a, the gap S2 is formed in the bending direction by the groove 34.

The front surface 25 of the hollow seal portion 24 is formed along the molding intermediate surface 33 outside the vehicle cabin from the locking piece 35, and the front lower portion 26 reaching the base portion 21 from an intermediate position 25a of the front surface 25 is formed. The locking piece 35 is formed in an inverted L-shaped cross section with a gap S1 in the vehicle width direction. The molding intermediate surface 33 is provided with a molding tip 31 protruding from the periphery of the windshield 4 and integrally formed with a lip-shaped seal portion 9 which is pressed against the periphery of the windshield 4.

As a result, the hollow seal portion 24 is not directly supported on the molding intermediate surface 33, and a space is also formed around the back surface 28 only with its front surface 25 facing. Further, gaps S1 and S2 exist in the bending direction in the front surface 25 and the front end 21a.

The weather strip 20 is supported by the drip channel 6 at the rear end of the base 21, and the front end 21 a is pressed against the locking piece 35 by the bending elasticity of the base 21 and locked. Positioning in the width direction is performed. Therefore, the hollow seal portion 24 is not fixed to the windshield side molding 30, and deformation due to its installed state is suppressed. The base 21 can be bent by its elasticity. Therefore, when the front door panel 1 is closed, the front surface 25 of the hollow seal portion 24 bends along the molding intermediate surface 33 of the windshield side molding 30, and the base portion 21 is also hollow due to the existence of the gaps S1 and S2. The seal portion 24 is bent and displaced without being excessively bent. Therefore, the hollow sealing portion 24 smoothly deforms and displaces following the closing movement of the front door panel 1, and the sealing performance is improved. In addition, the hollow sealing portion 24 is deformed depending on the installation state, and the sealing performance is reduced,
This prevents the appearance from being impaired or increasing the bending load when the door is closed. Assuming that the base portion 21 has flexibility, the hollow seal portion 24 is formed so as to be able to reliably contact even if the front door panel 1 is misaligned outside the vehicle, so that the front door panel 1 is closed. Generation of wind noise can be avoided by securing the sealing performance.

FIG. 2 shows another embodiment of the present invention, in which the weather strip 20 has the same structure as described above, but the windshield side molding 40 made of synthetic resin or metal has a front end at the front end. The lip seal portion 9 is bent toward the glass 4 and has a rain gutter concave portion 41 so as to be in contact with the peripheral portion of the windshield 4.

[0014]

As described above, according to the present invention, the hollow portion of the weather strip is hardly deformed due to the variation in the construction of the front door, and is displaced in the door closing direction. Therefore, the deterioration of the sealing performance due to the deformation of the hollow portion, the generation of wind noise, the outward protrusion, the increase in the bending load when the door is closed, and the like are avoided.
