Active shock-absorbing seating system
First Claim
1. A active shock-absorbing seating system for attenuating high-G shock forces comprising a seat;
- a mount for said seat coupling said seat to a shock-receiving platform;
an adjustable shock-absorbing unit having first and second elements comprising said mount, said first 14 element being connected to the shock-receiving platform and said second element being connected to the seat;
sensor means for monitoring shock forces applied to said shock-receiving platform and received by said seat; and
control means coupled to said force sensor means and said shock-absorbing unit to vary the response of said shock-absorbing unit in response to shock forces applied to the shock-receiving platform.

Abstract
An active shock-absorbing boat seat system has a seat system mounted to the boat deck through an active shock absorber. Sensors monitor both the shock to be passed from the deck to the seat as well as the shock actually received by the seat after passing through the shock absorbing system. A controller monitors the shock levels and provides a continuing control signal to the shock-absorbing unit to control the response of the shock-absorbing unit during the duration of the shock. The control system can provide for adjustment of various operating parameters for the system, including initial position of the seating system, overall ride stiffness, maximum allowable shock, and other parameters.
