Decompression panel for an aircraft and an internal wall of an aircraft having such a decompression panel

A decompression panel for an aircraft, the decompression panel comprising:

• a frame provided with an opening;
• and
• a flap having a shaped defined by a plurality of edges and connected to the frame by a connecting system, the flap configured to assume at least one of two positions, a closed position in which the flap completely closes said opening and an open position in which the flap at least partially frees the opening, the flap configured to be moved from the closed position to the open position by a pressure difference between two sides of the decompression panel,
• wherein the flap and the frame are configured to be superposed over at least one superposition zone,
• wherein the connecting system comprises at least one elastomer part arranged on a face of the at least two superposition zones and a plurality of fixing elements passing through and fixing together the at least one elastomer part, the frame, and the flap, the at least one elastomer part shaped to conform to at least a portion of a shape of the opening or the flap,
• wherein, during a decompression event, the at least one elastomer part is configured to compress to transition the flap into the open position from the closed position to allow a fluid to pass through the opening past all edges from the plurality of edges of the flap, and
• wherein, during a compression event, the at least one elastomer part is configured to expand to transition the flap into the closed position from the open position to prohibit fluid from passing through the opening.
