The door of a vehicle is usually opened and closed more than the window. So the mechanical load on the door sealings is unequally larger than the one e on window sealings: on average, the door on the driver’s side is moved about 100.000 times, while a window is only moved about 10.000 times. Due to the resulting factor, glass run sealings are static sealings and door sealings are dynamic sealings.
