  • Patent number: 9259997
    Abstract: Disclosed is a center reinforcement structure of a panoramic sunroof that is coupled in a vehicle width direction between a front glass and a rear glass disposed at a ceiling of a vehicle. The center reinforcement structure may include a frame which is disposed in the vehicle width direction, and has one end that is tightly attached and fixedly coupled to a lower portion of the rear glass, and a first center reinforcement which is coupled to a lower portion of the frame, and has a first closed cross-sectional portion that is formed at one side of the first center reinforcement by sequentially bending a first plate to provide a first closed space, and a first joint portion that is formed at the other side of the first center reinforcement by overlapping both ends of the first plate substantially in parallel so that both ends of the first plate are in surface contact with each other.

  • Patent number: 8740295
    Abstract: An apparatus adjusts a parting line of a panoramic sunroof comprising a moving glass and a rail. The apparatus includes a fixing bracket, a moving bracket, and a slide structure. The fixing bracket is disposed on a side surface of a rear end of the moving glass to be tiltable and movable in a straight line. The moving bracket is disposed on a curved path of the rail to be movable along a curved trajectory. The slide structure is connected between the fixing bracket and the moving bracket to enable curved movement by allowing the moving bracket to spread from the fixing bracket when the fixing bracket moves in a straight line.
