Patent ID: 8469445

Claim:
A motor-vehicle headrest comprising: a support structure positioned horizontally rearward of a head of a person sitting in front of the headrest; and a cushion having a front face with a central portion directly engageable with the head of the person and with a pair of side portions horizontally flanking the central portion and not normally directly engageable with the head of the person, the side portions being stiffer than the central portion, the cushion having a rear face bearing rearward of the side portions directly on the support and forming between the side portions a substantially empty cavity at which the rear face is spaced at the central portion forward from the support to form rearward of the central portion a substantially empty chamber, the cushion being formed with a passage connecting the chamber with the exterior and being elastically deformable such that on forceful rearward engagement of the head of the person with the central portion of the front face the front face deforms into a forwardly concave shape with the side portions cupping the head of the person and the cushion expelling air through the passage from the chamber and limiting rearward movement of the rear face at the central portion on rearward deformation.
