Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a weather strip used in the belt line section of an automobile, and more specifically to a weather strip that can be used to raise and lower door glass that has a partially large curvature. This invention relates to a weather strip for automobiles that has been improved.

[Background Art] In the current common weather strip for the belt line part of an automobile, a lip part that elastically comes into close contact with the door glass is connected to the weather strip through a flat base part.
It is attached and fixed to the door trim or door inner panel, and the only movable part is the lip.

Therefore, in order to raise and lower a door glass that has a partially large curvature as shown in FIG. You must do so. However, in this case, because the lip portion becomes too large, problems such as deterioration in the appearance of the lip portion, increased deformation of the lip portion due to its own weight, and stick slip with the door glass are likely to occur. This narrows the permissible range of curvature of the door glass, which causes restrictions on the design of the door glass and, by extension, the design of the entire vehicle.

[Purpose of the invention] The present invention was made in consideration of the above facts, and it is possible to raise and lower a door glass that has a large curvature while keeping the dimensions of the lip part that comes into close contact with the door glass to the same as conventional ones. An object of the present invention is to provide a weather strip for an automobile that can accept and absorb biting caused by weather stripping.

[Structure of the device] In order to achieve the above purpose, the present device has the following features:
A mounting base that is fixed to the door inner panel that is located inside the vehicle body than the door glass in the door body that forms the storage section in which the door glass is stored; a lip base extending upwardly and integrally formed with the mounting base and facing the mounting base; and a lip base having elasticity extending from the lip base in a direction opposite to the mounting base and integrally formed with the lip base. a lip portion that directly contacts the door glass; an elastic member that is interposed between the mounting base and the lip base and biases the lip base in a direction opposite to the mounting base when the lip base is deflected; Extending from the upper end of the lip base toward the mounting base, the lip base is integrally formed with the lip base, and the door glass is brought into contact with the inner surface of the upper end of the vehicle interior trim that covers the door inner panel to which the mounting base is fixed. and a protrusion that is movable relative to the inner surface of the upper end of the vehicle interior trim.

[Embodiment of the invention] FIG. 1 is a cross-sectional view showing the belt line portion of an automobile to which an embodiment of the weather strip according to the invention is applied, with the door glass raised or closed.

In the figure, 10 is the door glass, 12 is the door body, and 20
3 is an outer weather strip, and 30 is an inner weather strip according to this embodiment. A reinforcing panel 16 is provided inside the door outer panel 14 of the door body 12.
are arranged, and a belt molding 18 is attached to the upper ends of both panels 14 and 16. The outer weather strip 20 has a conventional general shape, and its flat base is attached to the inside of the belt molding 18, and its lip portion is elastically in close contact with the door glass 10.

On the other hand, a reinforcing panel 24 is also disposed inside the upper end of the door inner panel 22 of the door body 12, and the space between these panels 22, 24 and the reinforcing panel 16 serves as a storage area for the door glass 10. Further, above the door inner panel 22, a door trim 28 is mounted as a vehicle interior trim that is positioned by a bracket 26 that stands up from the upper surface of the door inner panel 22 and covers both panels 22 and 24.

The inner weather strip 30 has a flexible base 3
It has 2. The base 32 is composed of a piece 34 as a mounting base and a piece 36 as a lip base extending upward from the lower end of this piece 34 and integrally formed with the piece 34. It has a roughly U-shaped cross section. An elastic body 38 as an elastic member made of rubber, sponge, etc. is interposed between the two pieces 34 and 36 of the base 32 to control the deflection of the entire base 32. A plate-shaped insert reinforcing material 40 is provided in a piece 34 of the base 32 on the side of the door inner panel 22, and the base 32 is attached and fixed to the reinforcing panel 24 via the piece 34.

Further, on the piece 36 of the base 32 on the side of the door glass 10, a lip part 42 is formed integrally with the base 32 and extends from the outer surface toward the door glass 10. A protrusion 44 extends in the opposite direction and is formed integrally with the base 32. The lip portion 42 elastically comes into close contact with the door glass 10 as in the conventional product, and the protruding portion 4
4 moves relative to the inner surface of the door trim 28 when the base 32 is deformed about its central bend. During this relative movement, the protrusion 44 moves toward the door trim 2.
It may slide while contacting the inside of 8. Thereby, the protrusion 44 closes the gap between the vehicle outer side end of the door trim 28 and the door glass 10 even when the gap is large. Note that a lip portion 43 having a similar structure protrudes below the lip portion 42.

The operation of the belt line section configured as described above will be explained with reference to FIG. As shown in FIG. 2, when the door glass 10 having a partially large curvature at the upper end is lowered, that is, opened, in a range where the amount of inward bite X due to the lowering of the door glass 10 is small, this bite is caused by the lip of the inner weather strip 30. This is absorbed by the portion 42 being bent.

However, when the amount of biting X exceeds the range that can be absorbed by the lip portion 42, the U-shaped base portion 32 of the strip 30 bends while compressing the elastic body 38 interposed between the two pieces 34, 36. Absorbs bites that exceed the above range. Therefore, door glass 1
0 is a simple quadratic curved surface, but even if the door glass 10 is a complicated cubic curved shape that is curved along the longitudinal direction of the vehicle, the base 32 is fixed according to the curved shape. The lip portion 42 is brought into close contact with the door glass 10. Also,
In this case, the protrusion 44 of the weather strip 30 moves relative to the inner surface of the door trim 28, and
and the door inner panel 22. Therefore, the space between the door glass 10 and the door trim 28 is reliably closed by the protrusion 44, and the protrusion 44 is not exposed to the outside, giving a good appearance.

When the door glass 10 is raised or closed, the base portion 32 and the lip portion 42 return to their original positions through a process reverse to that described above, resulting in the state shown in FIG.

In the above embodiment, the deflection of the base 32 is controlled by the elastic body 38 interposed between the two pieces 34, 36, but this can be modified in various ways. For example, FIGS. 3 and 4 show an example of this, and in this example, a metal insert 46 having spring characteristics is embedded in the base 32, and the amount of deflection is controlled by the elasticity of this insert 46. It's summery. A plurality of slits 48 are cut into one side of the insert 46 to adjust the elastic force.

Further, the elastic body 38 having the structure of the first and second embodiments may be added to the structure of FIGS. 3 and 4.

In the above embodiment, the weather strip has a substantially U-shaped cross section, but the present invention is not necessarily U-shaped, but has a structure in which a part for attaching a flexible lip protrudes from the part for attaching it to a door, etc. Good to have.

[Effects of the invention] According to the weather strip according to the invention having the above-mentioned configuration, the presence of the mounting base, the lip base, the elastic member interposed between them, and the protrusion protruding from the upper end of the lip base makes it possible to prevent the weather strip from touching the door glass. Even though the dimensions of the closely spaced lip portions are the same as before, the tolerance range of the curvature of the door glass that can be used is increased. Therefore, it is possible to use a two-dimensional curved surface having a partially large curvature without spoiling the interior design, and it is therefore possible to improve the exterior design of the vehicle body or reduce air resistance. Furthermore, since the degree of freedom in the design of the door glass parting is increased, the glass housing portion can be designed freely even in a vehicle body with many curved sections, and it is therefore possible to improve the ease of getting in and out of the vehicle.
