When the sun visor body rotates around the X axis, to the lowest position of its lower edge, THEN, for the category M1 vehicle, the lower edge of the sun visor may be within the range 0° ~ 2° of the pitch angle, which is determined by the V1 point specified in GB 11562-2014. For the other categories of vehicles, the lower edge of the sun visor may be located within the range 0° ~ 4° of the pitch angle, which is determined by the V1 point specified in GB 11562-2014. when the sun visor is not in use, it shall not reduce the driver’s front vision. 4.1.3 The body of the sun visor shall be made of energy-absorbing and shock- absorbing materials OR the surface covered with flexible materials OR designed as an energy-absorbing and shock-absorbing structure. The sun visor shall not have sharp corners. The sun visor of category M1 vehicles shall meet the requirements of GB 11552. 4.1.4 The sun visor shall be adjusted flexibly, smoothly, without abnormal noise. It can be stopped at any position, in the work area; it shall not change position with the vibration of the vehicle body. 4.1.5 For vehicles, which are equipped with airbags on the front passenger side, the sun visor's label shall meet the requirements of GB 11551. 4.2 Appearance requirements 4.2.1 The color and pattern of the sun visor shall be consistent with the color plate or sample, which is approved by the specified procedures. 4.2.2 If heat-sealed seams are used around the sun visor, the height of the heat- sealed seams shall not be greater than 0.5 mm. 4.2.3 The sun visor body and accessories shall have a smooth appearance, without warping. 4.2.4 The skin of the sun visor shall be free from defects, such as wrinkles, bumps, ripples, slack, cracks, stains, peeling off of warning labels. 4.2.5 The surface of plastic parts shall be smooth and free of defects, such as burrs, warpage, obvious parting lines. 4.2.6 The metal installation parts must be corrosion-resistant; the surface shall be smooth AND free from cracks or rust.
