Dynamic antiwhiplash apparatus and method
First Claim
1. A passenger seat protection system for a seated passenger of a vehicle, comprising:
- a seat back supporting a pressurizable vessel storing a quantity of pressurized gas within a compartment, said compartment defined by one or more walls that collapse responsive to a force applied to said seat back by the seated passenger in a rear impact of the vehicle;
a headrest including a bladder responsive to a gas pressure from said quantity of pressurized gas to transition an expansion of said headrest from a first expansion mode to a second expansion mode; and
a gas channel communicating said quantity of pressurized gas to said bladder after a collapse of said one or more walls.
