  • Patent number: 11293549
    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.

  • Publication number: 20200207196
    Abstract: A removal seal for emergency access and egress for panels in transit vehicles has a pair of exit panel side wings separated by two key cavities. A locking strip is inserted within the two key cavities to urge the exit panel side wings against the exit panel to secure the exit panel. The locking strip may then be removed with relative ease such that the exit panel may be freed from the exit panel side wings and released. A method for achieving such a task is also disclosed herein.
