A decompression panel assembly for use in an aircraft includes a frame including a first surface and an opposing second surface, wherein the frame defines a grille opening and at least partially defines a flow path opening. The decompression panel assembly also includes a face panel having a first surface retained against the frame second surface such that the face panel at least partially covers the grille opening. A retention mechanism is coupled to the face panel and is configured to retain the face panel against the frame in a closed position.

A decompression panel assembly for use in an aircraft includes a frame including a first surface and an opposing second surface, wherein the frame defines a grille opening and at least partially defines a flow path opening that are each defined between the first and second surfaces. The decompression panel assembly also includes a first panel and a second panel pivotally coupled together at a central hinge. A retention plate is releasably coupled to the first and second panels and is configured to move between a closed position and an open position. The first and second panels at least partially cover the grille opening in a planar position when the retention plate is in the closed position, and the first and second panels move away from the grille opening to a folded position when the retention plate is in the open position.

A pressure bulkhead system comprises a pressure bulkhead adapted to be connected to a fuselage of a vehicle to separate a pressurized cabin space of the vehicle from an unpressurized cabin space of the vehicle, and a peripheral pressure frame to sealingly connect the pressure bulkhead to the vehicle fuselage. The peripheral pressure frame comprises an attachment section sealingly attached to an outer rim portion of a first surface of the pressure bulkhead. The first surface, when the pressure bulkhead system is installed in the vehicle, faces the unpressurized cabin space of the vehicle. A flange section is adapted to be sealingly attached to an inner surface of the vehicle fuselage and extends in a direction facing away from the first surface of the pressure bulkhead. A flexible section interconnects the attachment section and the flange section and is flexible to accommodate cabin pressure acting on the pressure bulkhead.

An assembly for use in a vehicle cabin includes a floor coupling structure and a sidewall coupling structure. The floor coupling structure includes a floor interface portion and a sidewall interface portion that extends transversely relative to the floor interface portion. The floor interface portion is configured to attach the floor coupling structure to a floor assembly of an internal cabin of a vehicle. The sidewall coupling structure has at least one friction-fit portion and a sidewall attachment section. The sidewall attachment section is configured to couple the sidewall coupling structure to a sidewall assembly of the internal cabin. The at least one friction-fit portion is configured to couple to the sidewall interface portion of the floor coupling structure.

A grille for a vehicle wall opening may comprise a frame, a pair of first louvers, and a second louver. The frame may be receivable on the vehicle wall in an installed position extending around the opening, and may have an inboard side and an outboard side. The pair of first louvers may be supported on the frame, and may be transversely inclined to an outboard direction at a first angle. The second louver may be located between the first louvers, fixed relative to the first louvers, and inclined to the outboard direction at a second angle different from the first angle.

A locking mechanism for a door panel to be positioned within and out of blocking relationship with an opening. Mechanism includes a deadbolt rotatably connected to the wall and having a curved configuration and a locking bracket connected to the door panel. The locking bracket extends from the door panel in an angular direction with respect to a plane of door panel. With door panel in a closed position and deadbolt in a first position, the locking bracket extends through the curved configuration. Deadbolt is in blocking relationship with the locking bracket in a direction along a plane of the door panel and is not in blocking relationship in a direction along the locking bracket. With door panel in closed position, deadbolt is in a second position not in blocking relationship with the locking bracket permitting door panel to move in a direction along a plane of the door panel.

A decompression device has at least one decompression member which is arranged on a supporting structure and which, in the event of differential pressure of a predetermined level, opens an opening in the supporting structure that acts as a connection between two volumes, wherein the decompression member can move between a retention position, in which the decompression member closes the opening, and a released position, in which the decompression member opens the opening, and has a locking arrangement which, when in use, fixes the decompression member in the retention position. The locking arrangement is provided with at least one locking element, which is arranged on the supporting structure, and the decompression member is kept in the retention position indirectly by the locking element interacting with an air conduction part.

A decompression panel assembly for use in an aircraft includes a body portion comprising a plurality of frame members defining a plurality of openings in the body portion. The decompression panel assembly also includes a baffle member integrally formed with the plurality of frame members such that the baffle member removably obstructs at least one opening of the plurality of openings. The baffle member is configured for at least partial displacement from the at least one opening during a decompression event.

A latch assembly for a decompression panel in an aircraft includes a base and a swing arm hinged to the base and pivotable relative to the base about a hinge axis between a latched position and an unlatched position. A load pin fixed to the swing arm has a pin axis a fixed distance from the hinge axis. A spring secured to the base is positioned to exert a spring force against the swing arm when the swing arm pivots from the latched position to the unlatched position. A bracket securable to the decompression panel defines a slot retaining the load pin when the swing arm is in the latched position. The load pin is movable in the slot under relative motion of the bracket and the base with the swing arm in the latched position, and exits the slot when the swing arm pivots to the unlatched position.

A door system with a deceleration mechanism may be adapted to control an opening of a door module that separates compartments of an aircraft and includes a door panel and a door frame. During the opening of the door module, the door panel performs a rotational movement 389 above a floor structure of the aircraft. The deceleration mechanism is operable in a normal operation mode and a deceleration mode and comprises a hinge, a wedge-shaped component that is rotatably attached to the hinge, and an activation device. The activation device is coupled to the wedge-shaped component and switches the deceleration mechanism from operating in the normal operation mode to operating in the deceleration mode when a difference in pressure between the compartments exceeds a predetermined threshold.
