Abstract:
1. A stabilization device configured for minimizing downward displacement of a seat cushion of a vehicle seat upon vehicle impact, said stabilization device having a proximal end and a distal end and comprising: a first cylinder; a second cylinder disposed entirely within said first cylinder and cooperating with said first cylinder to define a conduit between said first cylinder and said second cylinder; a piston having a proximal side and a distal side and configured for sealingly sliding in said second cylinder so as to divide said second cylinder and define a first chamber adjacent said proximal side of said piston and a second chamber adjacent said distal side of said piston, wherein said first chamber and said second chamber are in fluid communication via said conduit; a rod coupled to said piston and extending through said proximal end of said stabilization device; a fluid contained within said first cylinder for fluid communication between said first chamber and said second chamber via said conduit; and a member disposed within said second cylinder and moveable upon vehicle impact to seal off fluid communication between said conduit and said second chamber so as to minimize downward displacement of the seat cushion upon vehicle impact.
