A respirator for emergency oxygen supply for passengers in aircraft, with a mounting container (1), which can be closed with a lid (2), is fastened above the row of seats, and accommodates at least one breathing mask and an exothermic chemical oxygen generator (3) connected to the breathing mask in a holder (4, 5). The pivotability of the lid of the mounting container is improved by rigidly arranging the holder on the mounting container (1) such that it permits the oxygen generator (3) to change its place by pivoting in the case of use.
