Description

  The present invention relates to an opening trim weather strip for automobiles that seals between a vehicle body opening / closing member that opens and closes an automobile opening / closing member and a periphery of the vehicle body opening.

Conventionally, the seal between the opening / closing member of the automobile opening and the periphery of the vehicle body opening is made by an opening trim weather strip 110 attached to the flange 7 of the vehicle body opening periphery 6 as shown in FIG.
As shown in FIG. 1, the flange 7 is formed by the front end of the outer panel 9 that defines the vehicle body opening peripheral edge 6, the front end of the inner panel 8 inside the vehicle, and the like.

The opening trim weather strip 110 attached to the periphery of the vehicle body opening of the automobile body is formed by extrusion molding and includes a trim portion 120 and a hollow seal portion 130 as shown in FIG.
The trim portion 120 is formed by the vehicle outer side wall 121, the vehicle inner side wall 122, and the bottom wall 123. The trim portion 120 holds the flange 7 formed on the periphery 6 of the vehicle body opening so that the opening trim weather strip 110 is attached to the vehicle body opening. Hold all around. The trim portion 120 is formed of a solid material or a fine foam material, an insert member is embedded therein, and an inner-side holding lip 124 and an inner-side holding lip 125 that hold the flange 7 are formed on the inner surface to hold the flange 7. is doing.

  The hollow seal portion 130 is integrally formed on the outer surface of the bottom wall 123 of the trim portion 120. When the back door as the opening portion opening / closing member is closed, the hollow seal portion 130 contacts the outer periphery of the back door, and The space between the vehicle body opening periphery 6 is sealed. The hollow seal portion 130 is formed of a sponge material so as to be in a flexible contact with the shape of the door frame 2 such as the unevenness and the curved surface, and to be surely sealed.

  When the opening trim weather strip 110 is attached to the flange 7, the opening trim weather strip 110 comes into contact with the tip of a garnish 150, which is an interior part of the vehicle, and seals between the garnish 150 and the trim portion 120. There is one in which a joint portion 126 is formed (for example, see Patent Document 1). However, in the hollow abutting portion 126, the degree of freedom of deformation is small, the weight increases, and a space is required.

  Further, as shown in FIG. 6, in the roof weather strip 210 that contacts and seals against the door glass 5, an interior lip 240 is formed at the front end of the vehicle interior side wall 222, and the front end of the garnish 250 or the like is contacted, Some cover and seal between the garnish 250 and the roof weather strip 210 (see, for example, Patent Documents 2 and 3). However, due to variations in dimensions of the garnish 250 and the like, as well as variations during assembly, gaps and wrinkles were generated between the interior lip 240 and the garnish 250, and the aesthetics were unfavorable, and the sealing performance was reduced.

  Further, as shown in FIG. 7, the opening weather strip 310 is provided with a hollow seal portion 330 and a trim portion 320, and a sponge material that abuts an interior member such as a garnish 350 on the outer surface of the vehicle interior side wall 322 of the trim portion 320. Some have an interior lip 340 that covers the tip of the garnish 350 or the like. In this case, the interior lip 340 has to be formed long in order to reliably cover the tip of the garnish 350, etc., even if there are variations in the dimensions of the garnish 350, etc., or variations in assembly.

  However, if the interior lip 340 is formed long enough to reliably cover the tip of the garnish 350 or the like, the interior lip 340 will wave when the opening weather strip 310 is attached to the corner of the periphery 6 of the vehicle body opening. In addition, there was a tendency to wrinkle, aesthetics were unfavorable, and the sealing performance was reduced. For this reason, there is one that prevents the wrinkle by providing the interior lip 340 with a bent portion 341 (see, for example, Patent Document 4). In this case, due to the sponge material, the rigidity was low and sufficient wrinkle prevention was not always possible.

Further, as shown in FIG. 8, the opening weather strip 410 is provided with a hollow seal portion 430 and a trim portion 420, and an interior lip 440 that abuts an interior member such as a garnish 450 on the outer surface of the vehicle interior side wall 422 of the trim portion 420. Some of them cover the tip of garnish 450 and the like. The interior lip 440 is composed of a solid portion 441 and a sponge portion 442, and the solid portion 441 is largely formed to the vicinity of the tip of the interior lip 440 (see, for example, Patent Document 5).
In this case, the rigidity of the interior lip 440 is large, and it is insufficient to reliably cover the front end of the garnish 350 or the like due to variations in dimensions of the garnish 350 or the like, or variations during assembly.
