Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a weather strip mounted along a door opening of an automobile body.

[Prior Art] In an automobile as shown in Fig. 1, a weather strip is attached along a door opening 1 of a vehicle body.
As shown in FIG. 4, a weather strip 4 of this type is a sealing wall that forms a hollow portion 43 between a base 41 and a mounting base 41 that is generally fitted to a retainer 2 provided along a door opening. 42, and the peripheral edge of the door glass 3 of the sashless door is pressed against the seal wall 42 when the door is closed.

[Problems to be solved by the present invention] By the way, this seal structure has a good sealing property,
Moreover, it is desirable that the door glass 3 is stable and that rattling does not occur during traveling. Therefore, if the sealing wall 42 is made thin and easily bent, the wrapping of the door glass 3 is improved and the contact area with the door glass 3 is increased, but the contact pressure is too small and the sealing performance is not necessarily improved, and the glass Stability is reduced and rattling occurs. On the other hand, if the sealing wall 42 is thick, the sealing property is deteriorated. Therefore, in consideration of these points, the thickness is usually set to about 2.0 to 2.2 mm, but rattling may occur during traveling.

Therefore, the present invention is to provide a weather strip having excellent sealing property and preventing rattling, and an object thereof is to solve the conventional problems.

[Means for Solving the Problems] As shown in FIG. 2, in the present invention, of the sealing walls 42 of the weatherstrip that are bent by the pressing of the door glass, the central portion where the door glass 3 is pressed is the sealing wall 42. The outer wall 42a is thinner than the other part, and the inner wall 42b is thicker than the other part and both ends of which are connected to both ends of the outer wall 42a. To do.

[Effect] As shown in FIG. 3, when the door is closed, the peripheral edge of the door glass 3 is pressed against the thin outer wall 42a, and the outer wall 42a bends, and finally the peripheral edge of the door glass 3 passes through the outer wall 42a to the inner wall. It is in a state of being pressed against 42b.

Then, the contact area of the peripheral edge of the door glass 3 is increased by being wrapped in the thin outer wall 42a and pressed against the inner wall 42b, so that the sealing property is good. Moreover, the inner wall 42
By being pressed against b, the door glass 3 has good stability and rattling is prevented. Further, since the entire seal wall 42 including the inner wall 42b has flexibility, the outer wall 42
When the inner wall 42b is pressed by the door glass 3 via a, the door closing force does not suddenly increase.

[Embodiment] In the embodiment shown in FIGS. 2 and 3, the weather strip 4 is hollow between the mounting base 41 held by the retainer 2 provided along the door opening of the vehicle body and the mounting base 41. It is manufactured by extruding sponge rubber, which has a seal wall 42 that forms the portion 43 and bends when the door glass 3 is pressed.

The central portion of the seal wall 42 against which the door glass 3 is pressed includes a thin outer wall 42a and a thicker inner wall 42a.
It has a double structure consisting of b. That is, the seal wall 42
Is a portion of the outer wall 42a that is thinner than the other portion from the end portion on the vehicle outer side toward the end portion on the vehicle inner side than the center in the width direction, and both ends of the inner wall 42b having substantially the same thickness as the other portion are Each is connected to both ends of the outer wall 42a. Outer wall 42
The outer surface of the seal wall 42 including a has an arch shape that projects in the direction of the door glass 3, the inner wall 42b projects toward the opposite door glass side, and has an arch shape that corresponds to the outer wall 42a, and the outer wall 42a and the inner wall 42b. A space 43 exists between and.

The thickness of the outer wall 42a is, for example, about 1.0 to 1.5 mm, and the thickness of the other portion forming the outer surface of the seal wall 42 with the outer wall 42a and the thickness of the inner wall 42b are about 2.0 to 2.2 mm. .

Then, when the door glass is closed, the peripheral edge of the door glass 3 is pressed against the outer wall 42a as shown in FIG. 3, whereby the door glass 3 is wrapped by the thin outer wall 42a from the inner surface to the end surface of the peripheral edge. At the final position, the door glass 3 is pressed against the thick inner wall 42b via the outer wall 42a.

As a result, the peripheral edge of the door glass 3 is wrapped in the outer wall 42a and is in contact with the outer wall 42a with a wide contact area, and is pressed against the inner wall 42b so that the surface pressure is high and thus the sealing property is good, so that water leakage does not occur even during high pressure car washing. There is no fear of. Further, since the peripheral edge of the door glass 3 is supported by the inner wall 42b as well as the outer wall 42a, the rattling of the door glass 3 during traveling is almost eliminated. Further, when the door glass is closed, the door glass 3 is received by the flexible outer wall 42a, so that the door closing force is also reduced. Further, the seal wall extending from the inner wall 42b to the end on the inner side of the vehicle has greater flexibility than the outer wall 42a, but has flexibility. Therefore, when the door is closed, the door glass 3 is pressed against the inner wall 42b via the outer wall 42a. When closed, the door closing force does not increase suddenly.
