Patent ID: 8382206

Claim:
A multi-position adjustable headrest, comprising: a support bracket affixed atop a seat back having a plurality of ratchet defined portions; an intermediate and three dimensional shaped component pivotally secured in a biased fashion to said ratchet defined bracket, said intermediate component having a pivotally supported and biased locking pawl which, depending upon a pivotal location of said intermediate component, engages a selected ratchet portion of said support bracket; and a pair of headrest bun supporting plates pivotally secured at upper ends to spaced apart sides of said intermediate component, said supporting plates further having lower arcuate extending channels through which extend pin supports projecting laterally from opposite sides of said ratchet support bracket; said pin supports traveling along said channels during forward displacement of said bun support plates, resulting from a re-adjustment force applied to a headrest bun, concurrent and anti-bias rotation of said intermediate component in a controlled fashion occurring relative to said upper end pivotal connection between said intermediate component and said support plates and said pivotal connection between said intermediate component and said ratchet support bracket, such that said pivotally supported locking pawl engages a selected ratchet portion of said support bracket between an initial position and at least one succeeding forward adjustment position.
