The granted patent (Publication Number: US11918492B2) discloses a seal component designed to removably secure to a suspension liner. The seal component comprises a single unitary body made from a polymeric material with at least one seal protruding radially outward between open ends. A textile sleeve, formed from a flexible textile material, extends from the body, providing greater elasticity. The design ensures concentric alignment with the liner central axis and includes features like ribs for reinforcement, friction-reducing regions, and a unique geometry for effective sealing.

Furthermore, the seal component features a specific construction where the seal extends upwardly from the body, overlapping an upper portion and including pitched segments designed to collapse for a secure fit. The integration of the textile sleeve with the body ensures inseparability during use, while the overall design aims to provide a comfortable and effective sealing solution for suspension liners. The patent highlights the innovative approach to seal component design, combining polymeric materials with textile elements for enhanced flexibility and sealing performance, catering to the needs of industries requiring reliable suspension liner seals.
