Abstract: A decompression device for an aircraft includes a cabin lining element, which has a first aperture for discharging exhaust air in normal operation of the aircraft and a second aperture for discharging a decompression air flow. The device also includes an unlockable closure element, which is fixable in a closing position in such a way that the second aperture is closed for air flow, and which after unlocking, can take a releasing position so that the second aperture is opened for air flow. The device also includes a locking device designed to fix the closure element in normal operation of the aircraft in the closing position, and is designed in the case of decompression to release the fixing of the closure element, so that the closure element can take the releasing position.

Abstract: A decompression device (10) for an aircraft includes a cabin lining element (20), which has a first aperture for discharging exhaust air in normal operation of the aircraft. According to the invention, the cabin lining element has a second aperture for discharging a decompression air flow. The device (10) also includes an unlockable closure element (30), which is fixable in a closing position on or in the second aperture (14) in such a way that the second aperture (14) is closed, and which after unlocking, can take a releasing position which is different from the closing position, so that the second aperture (14) is opened, and a locking device (40, 140 to 840), which is designed to fix the closure element (30) in normal operation of the aircraft in its closing position on or in the second aperture (14), and in the case of decompression to release the fixing of the closure element (30), so that the closure element (30) can take its releasing position.
