11. A swivel center beam for an aircraft seat base assembly, comprising:
-
A center body defining a center aperture having a first centerline axis; a first member extending from the center body having a first aperture for receiving a first sliding bar for coupling the first member to a first side rail; a second member extending from the center body having a second aperture for receiving a second sliding bar for coupling the second member to the first side rail; a third member extending from the center body having a third aperture for receiving a first fastener for attaching the third member to a second side rail; a fourth member extending from the center body having a fourth aperture for receiving a second fastener for attaching the fourth member to the second side rail; wherein the first member is configured to receive a pin for retaining the first sliding bar at least partially within the first aperture; and the pin is configured to shear in response to the swivel center beam moving relative to the first side rail. - View Dependent Claims (12, 13, 14, 15)
