  • a mount assembly, said mount assembly being adapted to be fixedly secured to the frame of the aircraft seat,said mount assembly including at least one guide member,a retraction assembly, aid retraction assembly including a generally horizontal support structured to generally define an upper support surface,said retraction assemble further including at least one guide element structured to b slidably engaged with said guide member of said mount assembly so as to guide generally vertical movement of said retraction assembly relative to said mount assembly between an extended position and a retracted position,lock means for locking said retraction assembly in said extended position, said lock means being releasable so as to permit movement of said retraction assembly into said retracted position upon a gentle but affirmative lifting force being applied to said retraction assembly when in said extended position,retraction resistance means for resisting a slight, momentary upward movement of aid retraction assembly from said extended position so as to prevent accidental release of said lock means, while still permitting facilitated release of said lock means, andsaid lock means comprising;

    a lock rod pivotally secured to said retraction assembly and structured and disposed to extend towards said mount assembly,a retention segment protruding outwardly from generally a lower end of said lock rod,a guide assembly operably coupled to said mount assembly, said guide assembly including a guide track structured and disposed to receive said retention segment of said lock rod slidably therein,said guide track being further structured to retain said retention segment of said lock rod in an elevated position, and thereby maintain said retraction assembly to which said lock rod is s cured in said extended position, until said retraction assembly, and therefore said retention segment of said lock rod, are lifted relative thereto to release the retention thereof from with said guide track,said guide track including an entry track, a central retention region, and an exit track, andsaid guide track further including a biased flap disposed over an outlet of said exit track and structured to permit said retention segment to exit said exit track therethrough without permitting re-entry of said retention segment into said exit track therethrough.
