US Patent 11535129 Vehicle seat mounting bracket for energy attenuating member

A vehicle assembly includes a vehicle body and a vehicle seat. The vehicle body includes a frame backing member elongated in a length direction of the vehicle seat. The vehicle seat includes a seat base and a seat back connected to the seat base. The seat back is connected to the frame backing member. A mounting bracket is connected to an upper portion of a seat back frame. An energy attenuating member positioned in a space between the seat back frame and the frame backing member interconnects the mounting bracket and the frame backing member. During a crash event the energy attenuating member is configured to collapse between the seat back and the frame backing member to absorb kinetic energy in the vehicle seat when the seat back is driven toward the frame backing member.
