Abstract

A dual-opening panoramic sunroof may include front glass which slides forward and rearward by being connected with a front sled that is slidable forward and rearward along a mechanism rail, a rear glass which slides forward and rearward by being connected with a rear sled, a front timing plate which has a rear end rotatably coupled to the rear sled, and a front end formed with a front groove to accommodate a portion of the front sled, and selectively connects the front sled and the rear sled, a rear tilt lever which is disposed rearward of the mechanism rail, and a rear timing plate which has a rear end rotatably coupled to the rear tilt sled, and a front end formed with a rear groove formed to selectively accommodate a portion of the rear sled, and connects the rear sled and the rear tilt sled.

First claim

What is claimed is:

1. A dual-opening panoramic sunroof comprising:
a front glass sliding forward and rearward by being connected with a front sled that is slidable forward and rearward along a mechanism rail disposed at either side of an opening formed in a roof panel of a vehicle;
a rear glass sliding forward and rearward by being connected with a rear sled that is slidable forward and rearward along the mechanism rail;
a front timing plate which has a rear end rotatably coupled to the rear sled, and a front end formed with a front groove to accommodate a portion of the front sled, and selectively connects the front sled and the rear sled;
a rear tilt lever which is disposed rearward of the mechanism rail, is rotatable by having a portion that is accommodated in a rear tilt sled that is slidable forward and rearward, and tilts up a rear portion of the rear glass;
a rear timing plate which has a rear end rotatably coupled to the rear tilt sled, and a front end formed with a rear groove formed to selectively accommodate a portion of the rear sled, and connects the rear sled and the rear tilt sled; and
a rear lever rotatable connected between a rear rail coupled to a lower portion of the rear glass and the rear sled, wherein the rear lever is movable with the rear sled along the mechanism rail and is configured to tilt up a front portion of the rear glass,
wherein both of the front glass and the rear glass are configured to slide after being tilted up toward an outside of the roof panel.

2. The dual-opening panoramic sunroof of claim 1 , wherein a front protrusion protrudes from one side of the front sled to be accommodated in the front groove, a front surface of the front groove is formed as a first front inclined surface having an obtuse angle, a rear surface of the front groove is formed as a second front inclined surface having an acute angle, and front and rear surfaces of the front protrusion are formed to have shapes corresponding to shapes of the first front inclined surface and the second front inclined surface of the front groove.

3. The dual-opening panoramic sunroof of claim 1 , wherein a rail trimmed portion is penetratively formed in a lower portion of the mechanism rail to restrict a lower end of the front groove of the front timing plate when the rear glass is closed.

4. The dual-opening panoramic sunroof of claim 1 , wherein a first rear protrusion protrudes from one side of the rear sled so as to be accommodated in the rear groove, a second rear protrusion is formed to be spaced apart from the first rear protrusion so as to support the rear timing plate, a front surface of the rear groove is formed as a first rear inclined surface having an acute angle, a rear surface of the rear groove is formed as a second rear inclined surface having an obtuse angle, and front and rear surfaces of the first rear protrusion are formed to have shapes corresponding to shapes of the first rear inclined surface and the second rear inclined surface of the rear groove.

5. The dual-opening panoramic sunroof of claim 4 , wherein a distance at which the first rear protrusion and the second rear protrusion are spaced apart from each other is identical to a width of the rear timing plate such that the rear timing plate is prevented from being moved vertically when the rear sled is moved.

6. The dual-opening panoramic sunroof of claim 1 , wherein a first rear tilt slit and a second rear tilt slit are curvedly and penetratively formed in the rear tilt sled, a first rear tilt protruding portion and a second rear tilt protruding portion, which are slidably accommodated in the first rear tilt slit and the second rear tilt slit, respectively, are formed on the rear tilt lever, and when the rear tilt sled is moved rearward, the first rear tilt protruding portion and the second rear tilt protruding portion are configured to slide along the first rear tilt slit and the second rear tilt slit, respectively, such that the rear tilt lever is rotated.

7. The dual-opening panoramic sunroof of claim 1 , further comprising:
a front lever which is rotatably connected between a front carriage plate coupled to a lower portion of the front glass and the front sled, and tilts up a front portion of the front glass.
