Flap-retaining clip for a pressure relief assembly

A pressure relief assembly comprising:

• a housing defining an air passage chamber having at least one opening;
• a membrane flap secured within the air passage chamber, wherein the membrane flap is configured to move into an open position to expose the at least one opening to relieve air pressure;
• and
• a plurality of flap-retaining clips that securely couple the membrane flap to the housing, wherein each of the plurality of the flap-retaining clips comprises:
• a main body having a face;
• a housing-connecting tab extending from a first end of the main body, wherein the housing-connecting tab is retained within a retaining channel formed in the housing;
• and
• opposed flap-retention wings laterally extending from opposite sides of the main body, wherein a portion of the membrane flap is trapped between the opposed flap-retention wings and the housing to securely couple the membrane flap to the housing,
• wherein at least a portion of the opposed flap-retention wings is stepped relative to the face of the main body.

A flap-retaining clip configured to securely couple a membrane flap to a housing of a pressure relief assembly, the flap-retaining clip comprising:

• a main body;
• a housing-connecting tab extending from a first end of the main body, wherein the housing-connecting tab is configured to be inserted into and retained within a retaining channel formed in the housing;
• opposed flap-retention wings laterally extending from opposite sides of the main body, wherein a portion of the membrane flap is configured to be trapped between the opposed flap-retention wings and the housing to securely couple the membrane flap to the housing, wherein each of the opposed flap-retention wings comprises an angled leading edge that downwardly and outwardly angles from a top end of the main body towards a first end, wherein bottom edges of the opposed flap-retention wings are configured to be separated from a front surface of a portion of the housing, wherein a portion of the membrane flap is configured to be trapped between the front surface and the bottom edges of the opposed flap-retention wings;
• a rounded tip configured to guide the membrane flap onto the flap-retaining clip;
• and
• an angled surface between the main body and the rounded tip.
