US Patent 11975840 Fuse link head impact criteria mitigating device

A head impact criteria (HIC) device for a controlling a breakover rate of a seatback of an aircraft seat, and a method of manufacturing the same, are disclosed. A first energy absorbing member is coupled to the seatback of the aircraft seat. A second energy absorbing member is coupled to a frame of the aircraft seat. A fuse link is encapsulated by the first energy absorbing member and the second energy absorbing member. In response to the HIC device being subjected to a threshold load associated with a dynamic event, the fuse link breaks and the first energy absorbing member and the second energy absorbing member rotate around the axis.
