Hinge mechanism for a sliding door
View Patent ↗A hinge assembly for coupling a sliding door of a vehicle to a drive unit for sliding the sliding door from an open position to a closed position, the drive unit causing the hinge assembly to slide within a guide track as the door moves between the open position and the closed position, the hinge assembly comprising: a first hinge portion; a second hinge portion, the first hinge portion being pivotally secured to the second hinge portion; a cable attachment being secured to the second hinge portion; and a guide surface disposed on a surface of the first hinge portion, the guide surface being configured to make contact with a portion of a cable having an end secured to the cable attachment when the second hinge portion is in a first orientation with respect to the position of the first hinge portion and the cable no longer makes contact with the guide surface as the second hinge portion moves from the first orientation to a second orientation with respect to the first hinge portion.
1. A hinge assembly for coupling a sliding door to a vehicle for sliding the sliding door from an open position to a closed position, the hinge assembly sliding within a guide track as the door moves between the open position and the closed position, the hinge assembly comprising:
a first hinge portion;
a second hinge portion, said first hinge portion being pivotally secured to said second hinge portion;
a cable attachment being mounted on said second hinge portion; and
a guide surface disposed on a surface of said first hinge portion, said guide surface contacting a portion of a cable for sliding the sliding door between the open and closed positions when said second hinge portion is in a first orientation with respect to said first hinge portion and said cable no longer contacting said guide surface as said second hinge portion moves from said first orientation to a second orientation with respect to said first hinge portion;
wherein said cable has an end mounted to said cable attachment; and
wherein said cable attachment moves closer to said first hinge portion as said second hinge portion moves from said first orientation to said second orientation.
2. The hinge assembly as in claim 1 , wherein said first hinge portion is pivotally secured to said second hinge portion by a pivot pin.
3. The hinge assembly as in claim 1 , wherein said first hinge portion further comprises a plurality of rollers for being slidably received within the guide track.
4. The hinge assembly as in claim 1 , wherein said first orientation of said second hinge portion corresponds to the open door position and said second orientation of said second hinge portion corresponds to the closed door position.
5. The hinge assembly as in claim 4 , wherein movement of said second hinge portion from said first orientation to said second orientation is caused when said first hinge portion travels in a curved portion of the guide track.
