A weather strip includes an attachment base (10) and a hollow seal portion (30). The hollow seal portion (30) is integrally moulded with the outer wall (11) of the attachment base (10), and it makes a resilient contact with the door (42) when the door (42) of a vehicle is closed. The hollow seal portion (30) has a first wall (31), second wall (32), third wall (33), fourth wall (34) and bridge (35). The bridge (35) is spanned between the second wall (32) and the fourth wall (34). The hollow seal portion (30) includes bending points which bend when the door (42) is closed. The bending points include a connection part (51) formed between the second wall (32) and the third wall (33), a connection part (52) formed between the third wall (33) and the fourth wall (34), and a connection part (53) formed between the first wall (31) and the fourth wall (34).

This invention relates to a weather strip for vehicles attached along the door opening of a vehicle body.
As shown in FIGS. 3 to 5, a conventional type of a weather strip is attached along the body 40 of a vehicle. The weather strip includes an attachment base 10 and a hollow seal part 20. The attachment base 10 is U-shaped in section and is attached to a flange provided along the opening of the door 42. The hollow seal part 20 is integrally moulded with the outside wall 11 of the attachment base 10 and makes a resilient contact with the door 40 when the door 40 is closed. The inside of the hollow seal part 20 is divided by the bridge 25. The side walls 11, 12 of the attachment base 10 are provided with protruding lips 15, 15 at inner sides thereof, which slide on the surfaces of the flange 41 when the attachment base 10 is attached to the flange 41. The inner side wall 12 is provided with a tongue-shaped seal lip 16. The inner metal member 17 is embedded in the attachment base 10.
Although the bridge 25 is provided in the hollow seal part 20 of this weather strip, the bridge 25 does not function as it should, since, as shown in FIG. 6, it allows the hollow seal part 20 to entirely deform. Therefore, as shown in FIG. 4, the hollow seal portion 20 is deteriorated in making a follow up performance along the curve of the corner part 60, thus, developing wrinkles in the corner part 60 in particular.
FIG. 1 is an expanded sectional view showing the preferred embodiment of the weather strip according to the invention, and is an expanded sectional view along line I—I in FIG. 4.
FIG. 2 is an expanded sectional view showing a deformation of the weather strip shown in FIG. 1.
FIG. 3 is an appearance of a vehicle body.
A preferred embodiment of the invention will be described below referring FIGS. 1 and 2. FIG. 1 illustrates a sectional view where the door 42 is about to make a resilient contact with the weather strip. FIG. 2 illustrates a sectional view where the door 42 has made a resilient contact with the weather strip.
The weather strip in this preferred embodiment comprises, as similar to the prior art shown in FIGS. 5 and 7, an attachment base 10 and a hollow seal portion 30. The attachment base 10 is attached to a flange 41 provided along with the opening for the door 40 of a vehicle body 40. The hollow seal portion 3 is integrally moulded with the outer side wall 11 of the attachment base 10. The hollow seal portion 30 makes a resilient contact with the door 42 when the door 42 of a vehicle is closed.
The attachment base 10 is made substantially U-shaped in section, having an outer wall 11, inner wall 12 and bottom wall 13. The bottom wall 13 connects the outer walls 11 and the inner wall 12. There are provided a number of protruding lips 15 at the inner surfaces of the outer wall 11 and the inner wall 12. The protruding lips slide over the surfaces of the flange 41 when the weather strip is attached to the flange 41. There is also provided a tongue-shaped seal lip 16 at the inner wall 12. The attachment base 10 comprises an inner metal member 17 which is embedded inside the base 10.
