Blast attenuation seat

A shock absorbing seat comprising:

• a shock absorber fixed to a roof or wall of a vehicle;
• a seat suspended from said shock absorber;
• a linkage providing a multi-degree of freedom connection between a bottom of said seat and said vehicle, to maintain stability of said seat;
• and
• wherein said linkage comprises a trailing arm.

A vehicle seat comprising:

• a vertically disposed post having an upper end and a lower end, the upper end of said post having a bracket for mounting to a vehicle;
• a vertically disposed tube slidably engaged about said post;
• a passenger seat, mounted to said tube;
• a shock absorber, one end of said shock absorber being fixed to said post and the other end of said shock absorber being fixed to said tube;
• a trailing arm, one end of said trailing arm being pivotally connected to the lower end of said post, and the other end of said trailing arm for being pivotally connected to said vehicle;
• and
• wherein said shock absorber is disposed within said post and tube.

A vehicle seat comprising:

• a vertically disposed post having an upper end and a lower end, the upper end of said post having a bracket for mounting to a vehicle;
• a vertically disposed tube slidably engaged about said post;
• a passenger seat, mounted to said tube;
• a shock absorber, one end of said shock absorber being fixed to said post and the other end of said shock absorber being fixed to said tube;
• a trailing arm, one end of said trailing arm being pivotally connected to the lower end of said post, and the other end of said trailing arm for being pivotally connected to said vehicle;
• and
• further comprising a fabric tether assembly to prevent rotation of said seat about said post, wherein a first end of said tether is pinned to a seat pan, and a second end of said tether is pinned to the trailing arm base.

A vehicle seat comprising:

• a vertically disposed post having an upper end and a lower end, the upper end of said post having a bracket for mounting to a vehicle;
• a vertically disposed tube slidably engaged about said post;
• a passenger seat, mounted to said tube;
• shock absorber, one end of said shock absorber being fixed to said post and the other end of said shock absorber being fixed to said tube;
• and
• a trailing arm, one end of said trailing arm being pivotally connected to the lower end of said post, and the other end of said trailing arm being pivotally connected to said vehicle;
• and
• a shear pin fixed between said post and said tube, the shear pin bearing the weight of said passenger seat until failing, at which point the shock absorber bears the weight of said passenger seat.

A shock absorbing seat comprising:

• a shock absorber fixed to the roof or wall of a vehicle;
• a seat suspended from said shock absorber;
• and
• a linkage, pivotable in multiple dimensions, between the bottom of said seat and said vehicle, to maintain stability of said seat;
• and
• a shear pin fixed between said seat and said shock absorber, the shear pin bearing the weight of said passenger seat until failing, at which point the shock absorber bears the weight of said passenger seat.
