Abstract: Previously known are headrests for the backrest of a seat of a motor vehicle, in particular for rear seats, which include a support mechanism which is attachable to a top edge of the backrest of a seat. A support element is provided which comprises an upholstered front surface to support a head and which is attachable to the support mechanism. Headrests of this type obstruct the view through the rear window and interfere when folding down the backrest of a seat. It is proposed to attach the support element so as to be movable around an axis of rotation from an operational position into a storage position. In the operational position, the support element is with its front surface substantially upwardly oriented, thus extending the backrest of a seat and projecting upwards from the backrest of the seat.

Abstract: A headrest and headrest positioning system reduces whiplash injuries from rear impacts by properly positioning the headrest behind the occupant's head either continuously, or just prior to and in anticipation of, the vehicle impact and then properly supports both the head and neck. Sensors determine the location of the occupant's head and motors move the headrest both up and down and forward and back as needed. In one implementation, the headrest is continuously adjusted to maintain a proper orientation of the headrest to the rear of the occupant's head. In another implementation, an anticipatory crash, is used to predict that a rear impact is about to occur, in which event, the headrest is moved proximate to the occupant. A pre-inflated airbag within the headrest automatically distributes the pressure to evenly support both the head and neck.
