Abstract

A cargo screen assembly for opening or closing an upper portion of a cargo space defined between a rear seat and a back door of a vehicle, the cargo screen assembly may include a cargo screen rail mounting groove formed horizontally in a rear surface of the rear seat of the vehicle, a plurality of side trims protruding rearward from respective opposite end portions of the rear surface of the rear seat, and a plurality of cargo screen rails configured to be inserted into the respective side trims or the cargo screen rail mounting groove.

First claim

What is claimed is:

1. A cargo screen assembly for opening or closing an upper portion of a cargo space defined between a rear seat and a back door of a vehicle, the cargo screen assembly including:
a cargo screen rail mounting groove formed horizontally in a rear surface of the rear seat of the vehicle;
a plurality of side trims protruding rearward from respective opposite end portions of the rear surface of the rear seat;
a plurality of cargo screen rails configured to be inserted into the respective side trims or the cargo screen rail mounting groove; wherein each of the cargo screen rails includes a first end portion and a second end portion; and
a latch structure mounted in each of the side trims at a point at which the side trims make contact with the second end portion of a corresponding cargo screen rail, the latch structure being configured to lock the corresponding cargo screen rail to a corresponding side trim or release the corresponding cargo screen rail from the corresponding side trim.

2. The cargo screen assembly of claim 1 , wherein the cargo screen rail includes:
a rotation shaft mounted to the first end portion of each of the cargo screen rails and configured to rotate the corresponding cargo screen rail in a first direction so that each of the cargo screen rails is inserted into the associated side trim, or to rotate the corresponding cargo screen rail in a second direction so that the corresponding cargo screen rail is inserted into the cargo screen rail mounting groove.

3. The cargo screen assembly of claim 2 , further including:
a gear spring assembly mounted to the rotation shaft and configured to rotate the corresponding cargo screen rail in the second direction.

4. The cargo screen assembly of claim 1 , further including:
cargo screens each including a first end portion mounted in the corresponding side trim, and a second end portion provided to be movable along the corresponding cargo screen rail mounted in the cargo screen rail mounting groove.

5. The cargo screen assembly of claim 4 , wherein each of the cargo screens includes:
a wheel mounted to a first side of the second end portion of each of the cargo screens and inserted into the corresponding cargo screen rail to be movable along the corresponding cargo screen rail; and
a coupling part mounted to the second end portion of each of the cargo screens, the coupling part being coupled to the second end portion of the opposite side cargo screen to close the upper portion of the cargo space.

6. The cargo screen assembly of claim 5 ,
wherein each of the cargo screens includes a plurality of panels,
wherein when the second end portion of each of the cargo screens is moved into the corresponding side trim, the plurality of panel are stacked in the corresponding side trim or wound in a form of a roll in the corresponding side trim to open the upper portion of the cargo space, and
wherein when the second end portion of each of the cargo screens is moved along the corresponding cargo screen rail, the plurality of panels are deployed along the cargo screen rail or unwound in a form of a roll to close the upper portion of the cargo space.

7. The cargo screen assembly of claim 1 , wherein the latch structure is configured such that, while the corresponding cargo screen rail is locked to the corresponding side trim, when force is applied to the second end portion of the corresponding cargo screen rail in the first direction, the latch structure is unlatched.

8. The cargo screen assembly of claim 3 , wherein the gear spring assembly includes:
a coil spring configured to apply force to the rotation shaft so that the corresponding cargo screen rail rotates in the second direction; and
a gear damper configured to reduce a speed at which the rotation shaft rotates.

9. The cargo screen assembly of claim 8 ,
wherein the rotation shaft includes a protrusion protruding vertically from the rotation shaft, and
wherein the gear spring assembly includes a rack gear configured, wherein when the rotation shaft rotates in the second direction, a first end portion of the rack gear contacts with the protrusion, and a rotational motion of the rotation shaft is converted into a linear motion by the contact, wherein the rack gear is moved away from the rotation shaft.

10. The cargo screen assembly of claim 9 , wherein the gear spring assembly includes:
a pinion gear configured to be rotated by movement of the rack gear; and
a gear link configured to transmit rotating force of the pinion gear to the rotation shaft and rotate the rotation shaft in the second direction.

11. The cargo screen assembly of claim 10 , wherein the gear spring assembly further includes:
a rack gear spring mounted to a second end portion of the rack gear so that when the rotation shaft rotates in the second direction, the rack gear spring is compressed by movement of the rack gear.

12. The cargo screen assembly of claim 11 , wherein the gear spring assembly further includes:
a locking device configured to maintain the rack gear spring in a compressed state when the cargo screen rail is mounted in the cargo screen rail mounting groove by rotation of the rotation shaft in the second direction.

13. The cargo screen assembly of claim 12 , wherein the gear spring assembly further includes:
a button device configured to release the rack gear from the locking device through a link structure so that the rotation shaft is rotated in the first direction by restoring force of the rack gear spring.

14. The cargo screen assembly of claim 8 ,
wherein the rotation shaft includes a protrusion protruding vertically from the rotation shaft, and
wherein the gear spring assembly includes:
a second rack gear;
a second pinion gear configured to be rotated by movement of the second rack gear;
a second gear link configured to transmit rotating force of the second pinion gear to the rotation shaft and rotate the rotation shaft in the second direction; and
a second rack gear spring mounted to a first end portion of the second rack gear and configured to apply restoring force to the second rack gear so that the second rack gear is moved.

15. The cargo screen assembly of claim 14 , wherein the gear spring assembly further includes:
a second locking device configured to maintain the second rack gear spring in a compressed state and configured such that, when the rotation shaft rotates in the second direction, the second locking device is unlatched by the protrusion.

16. The cargo screen assembly of claim 15 , wherein the gear spring assembly further includes:
a second button device configured to apply force to the second rack gear through a second link structure in a direction in which the second rack gear spring is compressed, so that the second rack gear spring is maintained in a state of having been compressed by the second locking device.

17. A method of operating the cargo screen assembly of claim 1 , including:
an operation of applying force to the second end portion of each of the cargo screen rails in the first direction to release a corresponding latch structure, and releasing the cargo screen rail from the corresponding side trim;
a first rotation operation of rotating the rotation shaft of the cargo screen rails in the second direction by restoring force of a coil spring;
an operation of bringing a protrusion of the rotation shaft into contact with a rack gear and thus moving the rack gear in a direction away from the rotation shaft;
an operation of rotating a pinion gear by a movement of the rack gear, and transmitting rota
