Abstract:
A releasable seal assembly is provided that may include a first extension profile and a second extension profile extending from a core. The first extension profile may include a first exit panel side wing resiliently hinged to the core, and a first host panel side wing extending from the core. The first exit panel side wing and the first host panel side wing may define a first key cavity, and the first exit panel side wing has a first arcuate surface that may define a first retention tongue recess of the first key cavity. Additionally, the first host panel side wing has a second arcuate surface that defines a second retention tongue recess of the first key cavity. The first exit panel side wing may include a first exit panel side wing tongue configured to be received within the second retention tongue recess.
