An extension mechanism for a passenger oxygen mask includes a guide block with defined channels to guide the rotation of a telescoping extension arm mechanism. After rotation, a rotating sleeve latch releases an internal telescoping arm that extends a pull flag for the passenger to grab and release the oxygen mask. A pull flag release mechanism releases the pull flag when the extension arm mechanism is fully extended. Combined spring biasing elements keep the pull flag secured in place while stowed and retract a pull flag retention pin at full extension.
