Patent number: 8702147Abstract: 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.Type: GrantFiled: May 8, 2013Date of Patent: April 22, 2014Assignee: Arcca IncorporatedInventors: Alan Cantor, Michael Markushewski, Gary R. Whitman, Daniel McDonough, Larry A. Sicher, Louis A. D'Aulerio, Donald K. Eisentraut, Tim Keon

Patent number: 5553924Abstract: A vehicle safety seat system includes a contoured vehicle seat bottom and a foam layer disposed over the supporting vehicle seat bottom and supported by the supporting vehicle seat bottom. The foam layer has a rate sensitive compression characteristic. The rate sensitive compression characteristic is a compressive response to a slow application and a rigid response to a rapid application of force. To adapt an existing seat bucket to the desired configuration, a rigid foam layer may be molded within the supporting vehicle seat bottom. This rigid foam layer is contoured and disposed at an angle with respect to the horizontal. Seat belts having a pretensioner device are also provided. The pretensioner device is controlled according to both a frontal crash sensor and a vehicle-off ground control system to couple occupant to the seat bottom prior to a wheels first landing.Type: GrantFiled: November 15, 1994Date of Patent: September 10, 1996Assignee: The Board of Trustees of the University of Alabama for its division, The University of Alabama at BirminghamInventors: Alan E.
