Abstract:
A multi-position and manually adjustable headrest having a support bracket affixed atop a seat back and exhibiting a plurality of ratchet defined portions. An intermediate and three dimensional shaped component is pivotally secured in a biased fashion to the ratchet defined bracket, the intermediate component exhibiting a pivotally supported and biased locking pawl which, depending upon a pivotal location of the intermediate component, engages a selected ratchet portion of said support bracket. A pair of headrest bun supporting plates are pivotally secured at upper ends to spaced apart sides of the intermediate pivotal component, the supporting plates further exhibiting lower arcuate extending channels through which seats pin supports projecting laterally from opposite sides of the ratchet support bracket and travel along the channels during forward displacement of the bun supporting plates, such as resulting from a manual readjustment force applied to a headrest bun. Concurrent rotation of the intermediate component in a controlled fashion occurring relative to its upper pivotal connection to the support plates and lower pivotal connection to the ratchet support bracket such that the pivotally supported locking pawl engages a selected ratchet portion of the support bracket between an initial position and at least one succeeding forward adjustment position.
