The winding component includes a support element and a roller rotatably mounted there on. The cord fabric is entirely or partially wound around the roller. The cord fabric includes a light-transmitting section and a light-tight section which are connected along a stretching direction of the cord fabric. The light-tight section is arranged in front of the light-transmitting section along the stretching direction.
