Blast attenuation seat
First Claim
1. 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; 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 for being pivotally connected to said vehicle;
further comprising a linear actuator for adjusting the height of the passenger seat.

Abstract
Vehicle seats that reduce the potential for injury to occupants when the vehicle is subjected to a mine or similar explosive device. The seats are ceiling or wall mounted and include a trailing arm which allows for deflection while providing stability. The seat isolates the occupants from the chassis of the vehicle via a pneumatic or other shock absorber and/or a crushable element to provide protection from vertical and horizontal oriented blasts. These seats can also be combined with shock absorbing/isolating foot rests, appendage (leg) restrain systems and an occupant four-point harness to offer a completely integrated system. This integrated system reduces acceleration/deceleration related injuries, shock injuries to the lower legs, flailing injuries to the lower legs and internal collision injuries. Other options and alternatives are also described.
