The invention relates to a decompression element for pressure equalization in a cabin of an aircraft, with a decompression element frame, a flap, and a hinge element or at least one bearing element for fitting the flap to the decompression element frame. The hinge element or the bearing element can be produced from a plastics material. A decompression device for decompressing a cabin area includes a decompression device frame, a first opening which enables a flow to take place between a line of an air-conditioning system of the aircraft and the interior space of the decompression device, a second opening which enables a flow to take place between the cabin area and the interior space of the decompression device, and a third opening receiving the decompression element with the flap.

1. A decompression element for pressure equalization in a cabin of an aircraft, comprising: a decompression element frame;a flap;one of a hinge element and at least one bearing element for fitting the flap to the decompression element frame, wherein the flap is rotatable in two rotational directions
1. A decompression element for pressure equalization in a cabin of an aircraft, comprising: a decompression element frame;a flap;one of a hinge element and at least one bearing element for fitting the flap to the decompression element frame, wherein the flap is rotatable in two rotational directions away from a closed position in which the flap closes flow through the decompression element frame;at least one projecting element coupled to the flap so as to project away from the flap, at least one of the projecting elements including an engagement area; anda release device coupled to the decompression element frame and including a release device housing, a pressure element moveable relative to the release device housing, a spring biasing the pressure element into contact with the engagement area of the at least one projecting element when the flap is in the closed position, and an adjusting screw coupled to the release device housing and operable to adjust the bias applied to the pressure element, thereby defining a predetermined pressure difference across the flap at which forces applied by the predetermined pressure difference will overcome the bias applied to the pressure element to move the flap to an open position and enable flow through the decompression element frame,wherein when a pressure difference across the flap in either direction exceeds the predetermined pressure difference, the engagement area is released from contact by the pressure element such that the flap may rotate from the closed position to the open position. 2. The decompression element according to claim 1, wherein the decompression element is formed such that it enables a flow to take place between the cabin area and an area between an outer skin of the aircraft and a cabin lining when the flap is in the open position. 3. The decompression element according to claim 1, wherein the hinge element is formed in one piece. 4. The decompression element according to claim 1, wherein the hinge element or the bearing element is produced by a casting process, in particular an injection molding process. 5. The decompression element according to claim 1, wherein the flap and/or the decompression element frame are/is produced from fiber-reinforced plastics material and/or in sandwich construction. 6. The decompression element according to claim 1, wherein the hinge element is glued to the flap and/or the decompression element frame. 7. The decompression element according to claim 1, wherein the bearing element includes two bearing arms, wherein one bearing arm is disposed on the decompression element frame and another bearing arm is disposed on the flap, and the two bearing arms are connected to an axis. 8. The decompression element according to claim 1, wherein the hinge element or the bearing element is formed from a plastics material. 9. The decompression element according to claim 1, wherein the at least one projecting element is configured to be gripped to move the flap into the closed position. 10. A decompression device for pressure equalization in a cabin of an aircraft, comprising: a decompression device frame,a first opening via which an interior space of the decompression device can be connected to a line of an air conditioning system of the aircraft,a second opening via which the interior space of the decompression device can be connected to the cabin area,a third opening, andthe decompression element of claim 1, which is located at the third opening to selectively permit flow into or out of the interior space of the decompression device. 11. The decompression device according to claim 10, wherein when mounted in an aircraft and the flap is in the open position, the decompression element enables a flow to take place between the cabin area and an area between an outer skin of the aircraft and a cabin lining.
