Abstract: A regulator assembly for an aircrew breathing mask is provided The regulator assembly includes a support, a mode selection knob movable between a first position, a second position and a third position, the mode selection knob comprising a base pivotably mounted on the support with respect to an axis of rotation, and a cover supported by the base. The cover can be movable relative to the base between a locked position of the mode selection knob and an unlocked position of the mode selection knob, the locked position locking the rotation of the mode selection knob from the second position to the third position, the unlocked position permitting rotation of the mode selection knob from the second position to the third position.

Abstract: A control unit for an aircraft crew member's breathing mask, includes a support, a mode-selection knob pivotally mounted on a holder between at least a first position, a second position and a third position. A controller supplies a breathing cavity in three modes of operation depending on the position of the mode-selection knob. A locking/unlocking system includes an operating member moveable between a locking position and an unlocking position. The locking position blocks the rotation of the mode-selection knob from the second position to the third position, and the unlocking position allows rotation of the mode-selection knob from the second position to the third position.

Abstract: A regulator assembly for an aircrew breathing mask includes a support and a mode selection knob mounted with the ability to pivot on the support. The selection knob is able to pivot between at least a first position, a second position and a third position. The mask further includes regulator designed to supply a breathing cavity at least in three modes of operation according to the position of the mode selection knob. At least one locking/unlocking device locks and unlocks the rotation of the mode selection knob towards the third position. The locking/unlocking device comprising has an operating member that pivots between a position in which the rotation of the mode selection knob is locked, and a position in which the rotation of the mode selection knob is unlocked.

Abstract: A head armature for a respiratory system includes a cradle and a retention mechanism. The cradle is configured to receive a respiratory mask assembly in a stand-by position. The retention mechanism is configured to detachably connect the respiratory mask assembly with the head armature such that the respiratory mask assembly is movable from the stand-by position to a use position while connected to the head armature and such that the respiratory mask assembly is selectively detachable from the head armature in a stand-alone configuration whereby the respiratory mask assembly is disconnected from the head armature. In the use position, the respiratory mask assembly is configured to provide oxygen to a user. The head armature is configured to be worn on a head of the user such that the cradle is between the respiratory mask assembly and the user's head when the respiratory mask assembly is in the stand-by position.

Abstract: A breathing system for an aircraft crew member or passenger may include a face-fitting device, a storage area added to a seat headrest for retaining the face-fitting device in a storage position apart from the head, and a back portion for retaining the face-fitting device on the user's head when the breathing system is used. The back portion is retained on the headrest by a removable fixing mechanism when the face-fitting device is in the storage position, and the removable fixing mechanism is released upon the tightening the face-fitting device on the user's head.

Abstract: A protective system for aircraft pilot comprises a breathing mask, an eye protection and a safety device. The breathing mask is designed to supply the pilot with a respiratory gas and the breathing mask comprises an oxygen supply duct intended to be connected to an aircraft cockpit. The eye protection comprises a screen intended to extend between the pilot's eyes and an external space. The safety device comprises a display device and a support. The display device is able to display, notably in front of a pilot's eye, information intended to assist in the piloting of the aircraft. The support carries the display device so as to keep the display of information in front of the pilot's eye.

Abstract: A breathing system for an aircraft crew member or passenger comprises a face-fitting device (11), storage means added to a seat headrest (100) for retaining the face-fitting device in a storage position apart from the head, and a back portion (13) for retaining the face-fitting device on the user's head when the breathing system is used. The back portion is retained on the headrest by removable fixing means (21-24) when the face-fitting device is in the storage position, and said removable fixing means are released upon tightening the face-fitting device on the user's head.

Abstract: In a spring nut (10) for attachment onto a stud (12), having a substantially oblong seat for the stud (12), the seat having an axial insertion opening (32) for the stud (12) and a holding section for the stud (12), provision is made that the spring nut (10) completely encloses the seat on a front wall (28) opposite the insertion opening (32) and in the peripheral direction.

Abstract: In a fixation clip (10) for at least one line (18), with a frame (12) which defines a receiving space (14, 14a, 14b) for the line (18), into which space the line (18) can be introduced such that the frame (12) encloses the line (18) in circumferential direction, wherein an insertion opening (16, 16a, 16b) for the line (18) is provided at the frame (12), and with at least one swivel arm (22, 22a, 22b) mounted on the frame (12), which can be moved from a holding position, in which the line (18) is fixed in the receiving space (14, 14a, 14b), in a swivel direction (S) into an assembly position in which the line (18) can be introduced through the insertion opening (16, 16a, 16b) into the receiving space (14, 14a, 14b), a web (24) is provided, which with a first end is mounted on the swivel arm (22, 22a, 22b) and with a second end is mounted on the inside of the frame (12), wherein the web (24, 24a, 24b) includes at least one joint (34, 34a, 34b) and is folded in the assembly position.
