  • 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.
