Automotive sunroof apparatus and window panel assembly thereof
A window panel assembly includes a glass panel, a window frame and a sealing strip. The window frame is installed on the glass panel, the window frame includes an abutment seat extended therefrom. The abutment seat includes a connecting portion and an elastic arm portion. The connecting portion is connected to the window frame and the elastic arm portion. The elastic arm portion includes an abutment surface. The abutment seat includes blocking surfaces at two sides of the abutment surface. A buffer space is formed between the elastic portion and the window frame. The sealing strip is arranged at the window frame, and the sealing strip abuts against the blocking surfaces. Accordingly, the sealing effect of the window panel assembly during closing is improved without gaps.
