Description

Weather-strip inner}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip inner, and more particularly, to a weather strip inner which is designed to maintain airtightness and generate noises irrespective of whether moisture is generated or not in contact with a door glass.

The door of the passenger vehicle is usually constructed by coupling an outer panel and an inner panel on the outer side, wherein the door glass is mounted so as to descend, and the door panel elevating device and door opening / closing device are mounted on the inner panel So that the door trim is coupled.

Further, the door glass has a sealing structure for preventing moisture, dust, noise or the like outdoors from entering the room in a closed state. A weather strip is installed at the bottom of the door where the door glass is exposed. The weather strip is composed of a weather strip outer provided on the outer side of the door glass and a weather strip inner provided on the inner side.

The conventional weather strip has a structure in which a door and an outer are fixed to the inner panel (or door trim) and the outer panel, respectively, and a plurality of lips are formed so as to contact each other when the door glass rises.

1 is a view showing a structure of a weather strip.

In the drawing, reference numerals 5 and 6 denote an outer panel and an inner panel of the door, respectively. The outer panel 5 and the inner panel 6 are spaced apart from each other by a predetermined distance, and the side glass 2 is provided so as to be movable up and down between them. A door trim 4 is provided at an upper end of the inner panel 12.

The waste seats 3 and 4 have a plurality of elongated ribs extending from the waste seals and are made of elastic material such as rubber and are provided on both sides of the side glass 2. [ The outer side seal 3 provided on the outside of the side glass 2 is integrally formed with the outer side molding and the end of the rib is in close contact with the outer side surface of the side glass 2. [ The inside chamber 4 is fixed to the door trim by adhesion or caulking, and the end of the rib is in close contact with the inside surface of the side glass 2. [

In the waste chambers 3 and 4 as described above, a plurality of ribs extending from the waste chamber are closely attached to the side glass 2, thereby preventing dust, moisture or noise from entering the interior of the vehicle.

However, such a conventional structure has a problem in that the assembling tolerance at the time of assembling is large (excessive scattering of the assembled scale), and friction occurs at the contact portion when moisture in the ascending and descending direction of the door glass is generated.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a weather strip which is hermetic and does not generate a seam, regardless of whether moisture is generated or not when the door glass is brought into contact with the door glass.

In order to accomplish the above object, the present invention provides a weather strip inner which is fixed to a door trim along a longitudinal direction of a vehicle body, one side of which is fixed to a coupling portion of a door trim and the other side is in contact with a door glass, And a body having a contact surface which is brought into contact with the door glass when the glass rises, the contact surface being formed in an arcuate shape so as to be separated from the door glass toward the lower end, The body is protruded along the longitudinal direction of the vehicle body at the surface of the contact surface so that the door glass contacts the contact surface in a line.

The ribs may be parallel to each other and spaced apart from each other to form a plurality of ribs.

The rib may have a curved shape at a portion contacting the door glass.

In the body, a hollow hole may be formed along the longitudinal direction.

The hollow hole may be formed so that the inner diameter decreases toward the lower end.

A film portion for reducing the frictional force upon contact with the door glass may be mounted on the surface of the contact surface.

The body is formed with a wedge portion which is inserted and fixed into a mounting hole formed in a fastening portion of the door trim on a fixing surface facing the door trim, and the upper and lower sides of the wedge portion are formed such that the fixing surface is spaced apart from the door trim. May be additionally formed.

The first flange may be extended to the door panel such that the fastening portion is positioned on the lower side of the inner panel, and the fastening portion is disposed on the opposite side of the wedge portion.

The second flange may be bent to the door panel so that the lower panel of the coupling panel can be brought into contact with the inner panel.

According to the weather strip inner according to the present invention, when the door glass is lifted, the contact surface to be abutted is formed into a linear contact structure, minimizing the frictional force and reducing the possibility of occurrence of the joint.

In addition, since hollow holes are formed in the inner wall of the weather strip, the body can be elastically deformed efficiently, the assembling tolerance can be reduced as the first flange and the second flange are formed and the assembly direction is regulated, (Swinging) of the weather strip inner can be suppressed.
