Head restraint and method of making and using same
First Claim
1. Head restraint of a vehicle seat, in which at least one container having an elastically deformable, gas tight covering is integrated, said container being filled with a gas and at least partially with filling bodies and being provided with at least one duct which is connected to an evacuator assembly for an abrupt evacuation of the gas in the event of a crash and for refilling of the gas, a vacuum being applied automatically in the event of said crash, wherein the at least one duct is connected to a vacuum reservoir container of the evacuator assembly.

Abstract
A head restraint of a vehicle seat has at least one elastically deformable container integrated therein. The container is at least partially filled with filling bodies and gas. An abrupt evacuation of the gas in the event of a crash changes the collision impact characteristics of the head restraint.
