Abstract:
A vehicle safety seat system includes a seat, and a frame and support surface that are movable with respect to each other between rest and attenuated positions, wherein the frame and support surface are respectively a first and second distance apart. A biasing mechanism biases the frame and support surface to the rest position between blast and slam down phases. A damper coupled between the frame and support surface has blast and rebound recovery resistance settings. The blast resistance setting is set to a predetermined value based on a weight of a seat occupant. The damper, during the blast phase, resists motion between the frame and support surface toward the attenuated position based upon the blast resistance setting, and after the blast phase and prior to the slam down phase, resists motion between the frame and support surface toward the rest position based upon the rebound recovery resistance setting.
