Abstract
Abstract A headrest assembly includes a support plate attached to a seat and to which a head engaging padded member is movably attached. A pivot coupling extends between the plate and headrest for controlling the movement of the padded headrest toward and away from the support plate. In order to move the headrest, a fluid cylinder such as a pneumatic bellows is interposed between the support plate and the headrest.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
105 words
An adjustable headrest assembly for a vehicle seat comprising: support means for attachment to the back of a seat, said support means including a headrest support member; a headrest; a pair of orthogonally aligned pivot means each having multiple parallel pivot axes which are orthogonal to the pivot axes of the other pivot means for coupling said headrest to said headrest support member for guided and controlled movement toward and away from said headrest support member; and fluid cylinder means mounted between said headrest and said headrest support member for selectively moving said headrest to a selected position with respect to said headrest support member.
Claim 2
Dependent Claim
105 words
