Headrest for a seat of a vehicle including a frame attachable to the seat
and a fluid-containing bag attached to the frame. The bag allows movement
of the fluid within the bag to thereby alter its shape and enable it to
conform to the head and neck of an occupant. A deformable cover
substantially surrounds the bag and is elastically deformable in response
to changes in pressure in the bag. A protection system for protecting an
occupant in an impact includes an anticipatory crash sensor for
determining that a crash involving the vehicle is about to occur and a
movable cushioning arrangement coupled to the anticipatory crash sensor.
The cushioning arrangement is movable toward a likely position of the
occupant, ideally into contact with the occupant, upon a determination by
the anticipatory crash sensor that a crash involving the vehicle is about
to occur. The cushioning arrangement includes a frame coupled to the
vehicle and a fluid-containing bag attached to the frame. The bag allows
movement of the fluid therewithin to thereby alter its shape and enable it
bag to conform to the occupant.
