Patent granted for vehicle roof roller blind arrangement
The granted patent (Publication Number: US11987108B2) discloses a roller blind arrangement designed for motor vehicles. The system includes a roller blind web that can be wound up to form a fabric roll, along with two guide rails on either side of the web's center plane. These guide rails have infeed elements that form tracks for the guide strips, ensuring proper alignment and movement. The transverse frame part connecting the guide rails features support walls that are elastically deformable to compensate for tolerances, creating a one-piece injection-molded plastic part. Additionally, a winding shaft supports the fabric roll and is pivotally attached to the transverse frame part, enhancing functionality and ease of use.
Furthermore, the patent details various additional features and configurations of the roller blind arrangement. For instance, the support walls of the infeed elements have a maximum wall thickness of about 4 mm, ensuring optimal performance and durability. Each strip infeed element includes locking elements that engage with the guide rails, securely fixing the components together. Moreover, sealing elements are placed between the guide rails and the transverse frame part to enhance the system's efficiency. The transverse frame part is specifically designed as an injection-molded plastic part made of glass-fiber-reinforced plastic, while the guide rails are extruded aluminum profiles, highlighting the use of different materials for specific functionalities within the arrangement.
