Abstract

An embodiment inner belt mounting structure of a door for a vehicle includes an inner panel disposed inside the door of the vehicle, the inner panel including an installation groove, and an inner belt inserted into an upper end of the inner panel, wherein a first side of the inner belt is inserted in the installation groove, and wherein an inner belt joint of the inner belt is in contact with a frame of the door.

Claims (53)

1. A structure comprising:

an inner panel disposed inside a door, the inner panel comprising an installation groove; and

an inner belt arranged on an upper end of the inner panel,

wherein a first side of the inner belt is arranged in the installation groove,

wherein an inner belt joint of the inner belt is in contact with a frame of the door,

wherein the inner belt comprises a rear lip protruding from a surface of the inner belt in a length direction of the inner belt and in contact with an inner surface of the inner panel,

wherein the inner belt comprises a fixing portion fitted onto and fixed to the upper end of the inner panel and in contact with an outer surface of the inner panel,

wherein a lower end of the fixing portion is located higher than the rear lip,

wherein the lower end of the fixing portion is spaced apart from the inner panel, and

wherein the upper end of the inner panel is a single layer.

2. The structure of claim 1 , wherein a surface of the inner belt joint in contact with the frame is an inclined surface.

3. The structure of claim 1 , wherein a first side surface of the installation groove becomes an inclined portion in which a width of the installation groove becomes narrower toward a lower portion of the installation groove.

4. The structure of claim 3 , wherein the inclined portion is disposed at a side adjacent to the inner belt joint in the installation groove.

5. A structure comprising:

an inner panel disposed inside a door, the inner panel comprising an installation groove; and

an inner belt arranged on an upper end of the inner panel,

wherein a first side of the inner belt is arranged in the installation groove,

wherein the inner belt comprises:

an inner belt joint in contact with a frame of the door, and

a stopper protruding from a surface of the inner belt toward the inner panel, wherein the stopper is inserted into the installation groove,

wherein the inner belt further comprises a rear lip protruding from the surface of the inner belt in a length direction of the inner belt and in contact with an inner surface of the inner panel,

wherein the inner belt further comprises a fixing portion fitted onto and fixed to the upper end of the inner panel and in contact with an outer surface of the inner panel,

wherein a lower end of the fixing portion is located higher than the rear lip,

wherein the lower end of the fixing portion is spaced apart from the inner panel, and

wherein the upper end of the inner panel is a single layer.

6. The structure of claim 5 , wherein the stopper is disposed at a position spaced apart from the inner belt joint in a direction opposite to a center pillar of a vehicle.

7. The structure of claim 5 , wherein a second side surface of the installation groove becomes a support for supporting the stopper, wherein the second side surface is in contact with the stopper to prevent the inner belt from being pushed.

8. The structure of claim 5 , wherein the rear lip is positioned in a lower portion of the stopper.

9. The structure of claim 5 , wherein the rear lip is in contact with a bottom surface of the stopper.

10. The structure of claim 5 , wherein the stopper and the inner belt joint each comprise thermoplastic vulcanizates (TPV).

11. The structure of claim 10 , wherein the stopper comprises a material having a hardness that is greater than a hardness of the inner belt joint.

12. The structure of claim 5 , wherein:

the inner belt is extrusion-formed; and

the inner belt joint and the stopper are injection-molded.

13. A vehicle comprising:

a vehicle body comprising a center pillar;

a vehicle door coupled to the vehicle body and comprising a door frame;

an inner panel disposed inside the vehicle door, the inner panel comprising an installation groove; and

an inner belt arranged on an upper end of the inner panel,

wherein a first side of the inner belt is arranged in the installation groove,

wherein the inner belt comprises:

an inner belt joint in contact with the door frame, and

a stopper protruding from a surface of the inner belt toward the inner panel, wherein the stopper is inserted into the installation groove,

wherein the inner belt further comprises a rear lip protruding from the surface of the inner belt in a length direction of the inner belt and in contact with an inner surface of the inner panel,

wherein the inner belt further comprises a fixing portion fitted into and fixed to the upper end of the inner panel and in contact with an outer surface of the inner panel,

wherein a lower end of the fixing portion is located higher than the rear lip,

wherein the lower end of the fixing portion is spaced apart from the inner panel,

wherein the upper end of the inner panel is a single layer.

14. The vehicle of claim 13 , wherein the stopper is disposed at a position spaced apart from the inner belt joint in a direction opposite to the center pillar of the vehicle body.

15. The vehicle of claim 13 , wherein a second side surface of the installation groove becomes a support for supporting the stopper, and wherein the second side surface is in contact with the stopper to prevent the inner belt from being pushed.

16. The vehicle of claim 13 , wherein the rear lip is positioned in a lower portion of the stopper.

17. The vehicle of claim 13 , wherein the rear lip is in contact with a bottom surface of the stopper.

18. The vehicle of claim 13 , wherein the stopper and the inner belt joint each comprise thermoplastic vulcanizates (TPV).
