[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door inner weather strip, and more particularly to a door inner weather strip that can apply a constant pressure to a door glass.

[0002]

[Prior art]

 Conventionally, door inner weather strips have been used for vehicle doors. The door inner weather strip functions to prevent rain, dust and the like from entering the inside of the door through the gap between the door glass and the door trim, which slides vertically with respect to the door. FIG. 5 shows a front view of a vehicle door trim in which a conventional door inner weather strip is incorporated, FIG. 6 shows a sectional view taken along the line AA of FIG. 5, and FIG. 7 shows a part of FIG. The cross-sectional structure of the door inner weather strip) is shown in an enlarged manner. 5 to 7, the door inner weather strip 30 is fixed to the door trim 40. The door inner weather strip 30 is a metal plate base 31 into which an elastic rubber member 32 is fitted. The rubber material 32 includes a base portion 32a, a first lip portion 32b and a second lip portion 32c. A hollow portion 32d is formed in the second lip portion 32c. Further, a flock 32e is formed on a portion of the first lip portion 32b that abuts on the door glass 51, and a flock 32f is formed on a portion of the second lip portion 32c that contacts the door glass 51. The flocked hairs 32e and 32f are provided to improve sliding. The door trim 40 is formed by adhering a surface material 42 to a surface of a core material 41. A metal plate upper base 43 is fixed to the upper end of the back surface of the core member 41 in the figure, and a base 31 of the door inner weather strip 30 is fixed to the upper base 43 via a skin member 42. As shown in FIG. 7, the rubber thickness L of the door inner weather strip 30₁, L ₂ By adjusting, the magnitude of the pressure force with which the second lip portion 32c contacts the door glass 51 can be adjusted to an appropriate value. Note that 51b indicates the direction in which the door glass 51 moves up and down.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional example, when the door glass 51 is attached to the door, the distance between the inner surface 51a of the door glass 51 and the rubber member 32 varies due to the variation in the attachment position of the door glass 51 (arrow 51c). Direction or position shift in the direction of arrow 51d) occurs. For this reason, the magnitude of the pressure with which the second lip portion 32c abuts the inner surface 51a of the door glass 51 deviates from the desired value, so that the sealing performance between the door glass and the door inner weatherstrip becomes undesired when the door glass 51 moves up and down. It was perfect and had the drawback of producing abnormal noise. Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks, to keep the pressure at which the rubber material of the door inner weather strip comes into contact with the door glass at a predetermined value, and to keep the door glass and the door inner weather strip from rising and falling when the door glass is raised and lowered. It is an object to provide a door inner weatherstrip that has a perfect sealing property and does not generate abnormal noise.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the structure of the present invention is such that in a door inner weatherstrip having a rubber material that is pressed against a vehicle door glass and has elasticity, the bottom surface of the rubber material is brought into contact with one surface of the plate material. That is, a spring member is interposed between a base fixing both ends of the rubber member and the other surface of the plate member.

[0005]

[Action]

 According to the configuration of the above invention, one surface is in contact with the bottom surface of the elastic rubber material, and the elastic force of the spring material interposed between the other surface of the plate material and the base fixing both ends of the rubber material, The pressure at which the rubber material comes into contact with the door glass can be adjusted to a desired and appropriate value.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a usage example of the first embodiment of the present invention, and FIG. 2 shows a sectional structure of the first embodiment. 1 and 2, the door inner weather strip 10 comprises a base 11, a coil spring 12 as a spring material, a plate material 13 and a rubber material 14. The base 11 is made by bending a stainless plate. The coil spring 12 needs a proper spring constant in order to prevent abnormal noise when the door glass is raised and lowered. Therefore, the coil spring 12 is not limited to the three shown in FIGS. The number is decided. The plate member 13 is a metal plate or a plastic plate, and one surface 13a thereof abuts a bottom surface (bottom surface of the rubber material 14) 14g of a base portion 14a of a rubber material 14 described later, and the other surface 13b thereof is a coil spring. Abut the end of twelve. The rubber material 14 is elastic and comprises a base portion 14a, a first lip portion 14b and a second lip portion 14c. The first lip portion 14b and the second lip portion 14c are integrally formed with the base portion 14a. A hollow portion 14d is formed on the second lip portion 14c. Both ends (both ends of the rubber material 14) 14e, 14f of the base portion 14a are fixed so as to be fitted to the base 11, and the bottom surface 14g of the base portion 14a is biased in the direction of the arrow 14h by the coil spring 12 via the plate material 13. Has been done. The door trim 20 is composed of a core material 21 and a skin material 22 adhered to the surface of the core material 21. The upper base 23 is formed by bending an iron plate, and is fixed to the upper end of the back surface of the core 21 by a screw (not shown) or a claw (not shown) formed integrally with the upper base 23. The base 11 of the door inner weather strip 10 is fixed to the upper base 23 via a skin material 22 by screws (not shown).

With the above configuration, when pressure in the direction of arrow 15 by the door glass (not shown) is applied to the first lip portion 14b and the second lip portion 14c, the first lip portion 14b and the second lip portion 14c are shown. The shape of the two-dot chain line changes to the shape of the solid line. At this time, since the plate member 13 receives the pressure applied from the door glass (not shown) by the entire plate member 13, the plate member 13 functions to make the pressure applied to the rubber member 14 uniform. Since the coil spring 12 is compressed by the pressure in the direction of the arrow 15, the distance between the base 11 and the plate member 13 becomes short. Further, this shorter distance becomes longer as the pressure in the direction of the arrow 15 becomes larger. Therefore, the larger the pressure in the direction of the arrow 15 is, the larger the amount of the pressure in the direction of the arrow 15 which is relaxed by the coil spring 12 is. Therefore, even if there is a variation in the attachment position of the door glass (not shown) as in the above-mentioned conventional example, the change in the pressure in the direction of the arrow 15 due to the variation in this position is significantly alleviated by the coil spring 12, so that It is possible to reduce the change in the pressure value in the direction of arrow 15. That is, the operation load of the rubber material 14 on the door glass can be made substantially constant. Therefore, changes in the shapes of the first lip portion 14b and the second lip portion 14c can be reduced. As a result, the sealing property between the door glass and the door inner weatherstrip becomes perfect even when the door glass is moved up and down, and the generation of abnormal noise can be further prevented.

FIG. 3 shows a sectional structure of a second embodiment of the present invention, and FIG. 4 shows a leaf spring used in this second embodiment. In the door inner weather strip 10a shown in FIG. 3, the leaf spring 12a is used instead of the coil spring 12 in the first embodiment. The other parts of the second embodiment are the same as the corresponding parts of the first embodiment. Therefore, also in the second embodiment, as in the first embodiment described above, even if the attachment position of the door glass varies, the change in the shape of the first lip portion 14b and the second lip portion 14c should be reduced. Therefore, the sealing property between the door glass and the door inner weather strip is perfect even when the door glass is moved up and down, and it is possible to further prevent the generation of abnormal noise.

[0009]

[Effect of device]

 As described in detail above, since the pressure of the rubber material of the door inner weather strip of the present invention abutting on the door glass can be maintained at a predetermined value, the door glass and the door inner weather strip can be lifted when the door glass is lifted. It is possible to complete the sealing property with and to prevent the generation of abnormal noise.
