Abstract

PURPOSE:To improve a sealing property by providing bent parts on two places, closer to an indoor side than a seal point, on a sealing wall, forming a side surface facing the door fringe part of a hollow sealing part to which the door fringe part is pushed, of a weather strip, and forming the sealing wall in a nearly S-shaped cross section shape. CONSTITUTION:A weather strip 3 has a fitting base part 31, having a C-shaped cross section, fitted to a drip channel 1 provided along a roof side, and a hollow sealing part 32 upwardly protruded from the upper end of the fitting base part 31. A side surface part 33 on an inner side out of the fitting base part 31 and the hollow sealing part 32 is composed of solid rubber, and a sealing wall 34 forming the side surface part on an automobile outer side consists of sponge rubber. Here the sealing wall 34 extends from the upper end, connected to the side surface part 33 on the indoor side, so as to be almost flush to a roof panel 10 to form an upper surface 341, is bent at a first bending part 342a and downwardly and nearly vertically extends to form a vertical surface 343, and is bent at a second bending part 342b and outwardly extends to be formed so as to be connected to the upper end of the fitting base part 31 to have a nearly S-shaped cross section.

As shown in FIG. 1, the weather strip 3 includes a mounting base 31 with a C-shaped cross section that is assembled into the drip channel 1 provided along the roof side, and a hollow seal portion that protrudes upward from the upper end of the mounting base 31. It is equipped with 32. The weather strip 3 is an extrusion molded body, and the mounting base 31 and the inner side surface portion 33 of the hollow seal portion 32 are made of solid rubber, and the seal wall 34 forming the side surface portion on the outside of the vehicle is made of sponge rubber. has been done. A first seal lip 35 extends inward from the base of the inner side surface 33, and a second seal lip 36 extends outward from the outer surface of the mounting base 31. It's out. In the assembled state, the upper end of the hollow seal portion 32 is in contact with the side edge of the roof, and the first seal lip 35 is in contact with the side surface of the roof side.

The seal wall 34 extends from its upper end connected to the side surface 33 on the inside of the vehicle so as to be substantially flush with the roof panel 10 to form an upper surface 341, and is bent at a first bending portion 342a and extends downward substantially vertically. It extends to form a vertical surface 343, is bent at a second bent portion 342b, and extends outward to connect to the upper end of the mounting base 31, and has a substantially S-shaped cross section.

Therefore, when the door frame 2 is pressed against the upper surface 341, the seal wall 34 deforms with good followability to the pressing mainly due to the bending of the bent portions 342a and 342b. As shown in FIG. 3, even if the position of the outer edge of the door frame 2 shifts downward due to variations in door installation, and the amount of push into the upper surface 341 increases, the push will not reach the bending portion 341.
42a and 342b are bent and the inclination angle of the vertical surface 343 changes, so that the bending is absorbed. The upper surface 341 is only displaced in the pushing direction of the door frame 2, and does not protrude as in the conventional case.

Furthermore, the door frame 2 is pushed into the bent portions 342a and 34.
2b, so even if the pushing amount changes due to variations in door installation, the sealing pressure hardly changes and remains almost constant. Furthermore, since the vertical surface 343 acts to support the seal wall 34 when the door frame 2 is pushed in,
The contact area between the door frame 2 and the upper surface 341 of the seal wall 34 is increased, which also has the effect of improving sealing performance.
