Abstract

A door curtain assembly having a variable screening rate structure may include an internal curtain provided to be wound in a door trim and having patterns; an external curtain provided to be wound in the door trim and having a plurality of patterns; a control knob to which an upper edge portion of the internal curtain and an upper edge portion of the external curtain are fixed, and which is configured to adjust the positions of the internal and external curtains so that a rate at which the patterns of the internal curtain and the patterns of the external curtain overlap with each other may be changed, whereby the screening rate may be adjusted; and a curtain hook disposed on an upper end portion of a door frame so that the control knob may be locked to the curtain hook.

First claim

What is claimed is:

1. A door curtain assembly having a variable screening rate structure, the door curtain assembly comprising:
an internal curtain provided to be wound in a door trim of a vehicle, with a plurality of patterns formed in the internal curtain;
an external curtain provided to be wound in the door trim of the vehicle and distanced from the internal curtain, with a plurality of patterns formed in the external curtain;
a control knob to which an upper edge portion of the internal curtain and an upper edge portion of the external curtain are fixed at positions spaced from each other with a predetermined distance, the control knob being configured to adjust positions of the internal curtain and the external curtain so that a rate at which the patterns formed in the internal curtain and the patterns formed in the external curtain overlap with each other is changed, such that a screening rate is adjusted; and
a curtain hook disposed on an upper end portion of a door frame, wherein the control knob is locked to the curtain hook in an orientation selected among a plurality of orientations,
wherein the control knob includes a locking bar extending from each of opposite sides of the control knob, and a retaining portion protruding from a front end portion of the control knob.

2. The door curtain assembly of claim 1 , wherein the patterns formed in the internal curtain are identical with the patterns formed in the external curtain.

3. The door curtain assembly of claim 1 , wherein the patterns formed in each of the internal curtain and the external curtain include patterns having different light transmittances and alternating with each other.

4. The door curtain assembly of claim 1 ,
wherein the internal curtain is elastically supported on an internal reel disposed in the door trim and the internal curtain is wound around the internal reel, and
wherein the external curtain is elastically supported on an external reel disposed in the door trim at a position distanced from the internal reel and the external curtain is wound around the external reel.

5. The door curtain assembly of claim 1 ,
wherein the upper edge portion of the internal curtain is fixed to an internal curtain bar disposed in a longitudinal direction of the vehicle, and
wherein the upper edge portion of the external curtain is fixed to an external curtain bar disposed in the longitudinal direction of the vehicle.

6. The door curtain assembly of claim 5 , further including:
a first link hinged at opposite end portions thereof to the control knob and the internal curtain bar to couple the control knob with the internal curtain bar; and
a second link hinged at opposite end portions thereof to the control knob and the external curtain bar to couple the control knob with the external curtain bar.

7. The door curtain assembly of claim 6 , wherein an elastic device is disposed between the control knob and the first link and configured to elastically support the control knob such that a rear end portion of the control knob which is configured to be manipulated by a user is moved downwards therefrom.

8. The door curtain assembly of claim 7 ,
wherein the curtain hook includes a locking depression formed to receive the locking bar so that the internal curtain and the external curtain remain extracted, and a locking protrusion to which the retaining portion is selectively locked.

9. The door curtain assembly of claim 8 ,
wherein the retaining portion is formed on the control knob to protrude from the front end portion of the control knob, and
wherein the locking protrusion is formed on the curtain hook and configured to receive the retaining portion when an angle of the control knob is adjusted.
