A single tool Allen Key 3/16, or 5/16 shall be used for unlocking of the attachments fasteners. The maximum force for the locking operation shall not exceed (5 1) daN, respecting er

    45、gonomic aspects. The (pure) seat installation time, comprising two (2) Fwd and two (2) aft fittings, shall not exceed one (1) minute. The last seat row may have a longer installation time due to restricted accessibility of a monument installation (e.g. Doghouses, partitions, etc.). The SLD shall not

    46、 include parts that have to be disassembled or removed from the device for seat position shifting, removal and installation. The locking motions of the fitting shall not damage the seat track, floor panels or any other component and their surfaces. A clear and reliable visible indication for the SLD

    47、 in locked position shall be incorporated in order to guarantee correct installation and engagement of the fitting. The SLD engagement/disengagement to the track shall be directly visible to personnel (e.g. quality inspector) standing in the longitudinal passenger aisle. Copyright European Committee
