Abstract
A pivoting headrest assembly including a bracket supported upon a seatback frame. A headrest support secures a bun and is pivotally secured to the bracket in a forward biased direction. A rotating sector is supported upon the bracket and is pivotally slaved to the headrest support. A cam is pivotally supported upon the bracket and biased in a first direction to abut the sector in an upright design position established by the headrest support. A contact portion extends from a location of the cam offset from its pivotal connection to the bracket. A lever is independently rotated and coaxially supported relative to the rotating sector in a first biased direction. The lever is actuated against the bias to engage the contact portion, with continued actuation causing the cam to pivotally disengage from the rotating sector, whereupon the headrest support and bun pivotally actuates to a forward dump position.
