US Patent 11186371 Energy absorbing assembly for passenger seats

An energy absorbing assembly for a passenger seat that includes a crushable energy absorbing element for safely capturing kinetic energy during an impact event. The energy absorbing assembly comprises a linkage which is mechanically connected with moving parts of the seat back or seat pan by a first attachment element and a second attachment element, and the linkage includes an extended portion that extends beyond one of the attachment elements. A crushable energy absorbing element is mounted around the extended portion of the linkage and connected thereto, so that the crushable energy absorbing element receives and absorbs energy by deformation when the seat back is pushed forward with sufficiently high energy.
