Abstract: A curtain track for an aircraft cabin enables curtain sliders to be quickly loaded into the curtain track. The curtain track is constructed of an elongate channel with a first end fitting on a first end of the channel and a second end fitting on a second end of the channel. There is a unique cutout in the bottom surface of the first end fitting that forms a curved slot surface that enables curtain sliders to be loaded into the channel of the curtain track through the cutout to quickly load the curtain onto the curtain track without disassembling any of the parts of the curtain track or removing the curtain track from its attachment to the aircraft cabin.

Abstract: A hybrid underlayment including a compliant material layer and a rigid material layer affixed to the compliant material layer. The compliant material layer exhibits a compression deflection as measured according to ASTM standard D-1056-14 in the range of from about 0.14 kilogram force per square centimeter to about 1.76 kilogram force per square centimeter, and a thickness of at least about 2 millimeters. The rigid material layer exhibits a thickness of at least about 0.5 millimeters and a flexural modulus of at least about 600 MPa and flexural strength of at least about 35 MPa in both the length and width directions, both flexural modulus and flexural strength as measured according to ASTM D790-17.
