Energy-absorbing seat assembly

摘要

A seat assembly can include a base, a linkage assembly, a seat, and an energy-management assembly. The linkage assembly can be supported by the base and include a return plate supported by the base for rotation about a first axis of rotation. The seat can be supported by the linkage assembly for movement relative to the base along a generally arcuate path. The return plate can be operable to rotate relative to the seat about a second axis of rotation. The energy-management assembly can be supported by the base for rotation about a third axis of rotation and supported by the return plate for rotation about a fourth axis of rotation. The energy-management assembly can include a biasing member configured to resist the movement of the seat relative to the base along the generally arcuate path.
