Abstract

A laterally floating latch hub assembly includes a latch key receptor translatably mounted within a rotatable latch actuation cam. Latch keys within a port door are received within the latch key receptor, which is capable of translating laterally to ensure a proper fit of the latch key within the receptor. Once received within the receptor, torque from the latch keys is transmitted to the latch actuation cam via the latch key receptor.
