Vehicle safety collision headrest system

摘要

A vehicle safety collision headrest system which substantially instantaneously moves a headrest of a seat from any manually adjusted position to a fully extended position. The system includes a pressure actuation assembly having combustible propellant or fluid tank fluidly connected to a cylinder. The cylinder is rigidly connected to a bottom of the headrest and upon the occurrence of a collision or abrupt stopping the pressure actuation system fires the cylinder upwardly which causes the headrest to extend to a properly adjusted position behind a passenger's head and neck. The pressure actuation system inflates a front airbag which extends between a bottom of the headrest and a top of the seat to fill the gap therebetween. The front airbag cushions the passenger's head and neck as the passenger is thrust rearward and protects the passenger's head and neck from contacting the cylinder and poles rigidly mounted to the bottom of the headrest. A rear airbag may be optionally provided to protect back seat passengers from contacting the rear of the front seat and its hardware as the back seat passenger is thrust forward. The safety collision headrest system can be installed in rear seats as well as in front seats.
