Aircraft seat frame with enhanced dynamic response

A frame beam member for an aircraft seat frame with enhanced dynamic response, comprising:

• a tubular volume including at least one wall with a first plurality of undulations and a second plurality of undulations sequentially arranged and extending radially outward along a length of the tubular volume, the first plurality of undulations and the second plurality of undulations being configured to allow the tubular volume to absorb energy of a compressive load applied during a flight scenario through local bending of the first plurality of undulations and the second plurality of undulations,
• the first plurality of undulations being configured to have a first curvature when unloaded, the first plurality of undulations being configured to have a second curvature when the compressive load is applied, the second curvature being greater than the first curvature, the second plurality of undulations being configured to have a third curvature when unloaded, the first curvature being greater than the third curvature by which the first plurality of undulations are configured to deform prior to the second plurality of undulations,
• the frame beam member being one of a plurality of frame beam members of the aircraft seat frame, the plurality of frame beam members being configured to couple to a plurality of joints of the aircraft seat frame, at least one joint of the plurality of joints or at least one frame beam member of the plurality of frame beam members being configured to couple to an aircraft body.
