Description

Vehicle door inside belt weatherstrip assembly and vehicle door equipped with the same

The present invention relates to a vehicle door inside belt weather strip assembly and a vehicle door equipped with the same. More specifically, a belt weather strip that can maintain a stable fixed installation on the inner panel while effectively blocking the inflow of rain or moisture into the inside of the vehicle door. It's about technology.

In general, vehicle door glass is installed to be lifted up and down by a window regulator installed on the door panel.

In addition, the part where the door glass appears in the side door is called the belt line part, and the door glass is supported by a belt weather strip installed along the belt line part when moving up and down.

Belt weather strips are installed in closed areas such as door glass, doors, and sunroofs to block the intrusion of rain, wind, dust, and dirt, while also insulating noise transmitted from outside the vehicle and blocking vehicle vibration when opening and closing the door. performs its role.

The weather strip installed on the door trim on the inside of the door glass is called the door inside belt weatherstrip, and the weather strip installed on the door outer panel on the outside of the door glass is called the door outside belt weather. It is called a door outside belt weatherstrip.

1 and 2 show an example of a vehicle door inside belt weather strip according to the prior art.

The door inside belt weather strip 10 may include a body 11, a coupling portion 13, an inner lip 15, etc.

The coupling portion 13 is bent and extends from the body 11 in the direction of the door trim 50, and a coupling groove may be formed in the space between the body 11 and the coupling portion 13.

The upper part of the coupling portion 13 may be inserted and fitted into the door trim rib 60 disposed on the door trim 50, and the door inner panel 70 may be inserted into the coupling groove between the body 11 and the coupling portion 13. ) can be inserted to secure the door inside belt weather strip (10).

And the inner lip 15 extending from the lower part of the body 11 may contact the door glass (G).

This door inside belt weather strip 10 is manufactured in a straight line along the longitudinal direction of the door trim 50.

As the door inside belt weather strip (10) is arranged in a straight line along the longitudinal direction of the door trim (50), rain or moisture flowing in along the door class (G) remains on the surface of the door inside belt weather strip (10). This can cause problems with moisture or moisture penetrating into the inside of the vehicle door.

In addition, the door inside belt weather strip 10 according to the prior art is fixed to the inner panel 70 inserted into the coupling groove through a pressing protrusion protruding from the body 11 and the coupling portion 13 toward the coupling groove. Shocks are generated from time to time in the process of opening and closing the vehicle door, and due to the accumulation of these shocks, there is a problem that the fastening with the inner panel (70) inserted into the coupling groove of the door inside belt weather strip (10) becomes loose, which causes the door inside belt weather strip (10) to become loose. There is a problem of noise occurring due to a rubbing phenomenon between the pressing protrusion of the belt weather strip 10 and the inner panel 70.

Japanese Patent Registration No. 6287253

The present invention was developed to solve the problems of the prior art as described above. As the door inside belt weather strip is arranged in a straight line along the longitudinal direction of the door trim, rain or moisture flowing in along the door class is prevented from entering the door inside. It may remain on the surface of the belt weather strip, and as a result, we aim to solve the problem of moisture or moisture penetrating into the inside of the vehicle door.

In addition, we are trying to solve the problem that the connection with the inner panel inserted into the coupling groove of the door inside belt weather strip becomes loose due to the accumulation of shocks that occur from time to time in the process of opening and closing the vehicle door.
