摘要

an aircraft emergency exit door (10) with opening mechanisms integrated by a grouping of said mechanisms in a door bar (3) positioned on one side of a standard sized window (16). In said bar an inner handle (1) is mounted on a mainshaft (102) connected to a locking shaft (8a) on which a locking / locking door mechanism (83) is mounted against return springs (83). 8) comprising a lock (81). a conditional door opening mechanism (100) comprises a vent flap (110), a pivot connection (12) for coupling flap (110) to the inner handle (1), and a locking shaft (120) having , at each end, a pressure lever (121) equipped with brackets for locking (122) and unlocking (123) the tab (110). return springs (32) mounted against the conditional opening mechanism (100) are calibrated to allow said flap (110) to open under reduced pressure under varying residual pressure conditions, and to prevent it from opening under overpressure conditions .
