  • Seat locking mechanisms
    Publication number: 20040200926
    Abstract: Locking mechanisms for backrest portions of (typically vehicle) seats are detailed. The mechanisms avoid any need to use conventional recline locks and thus simplify the designs of existing seats otherwise so equipped. The mechanisms also permit adjustment of the positions of the backrests relative to the bases prior to deployment and allow for tolerances as well.
