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 sector is pivotally secured to the bracket and to which is attached the headrest support. A release catch is pivotally supported at a further location of the bracket and is biased in a first upward direction so that the catch abuts a projecting pin associated with the sector in an upright design position established by the headrest support. A cable is secured to a support fixed to a side of the bracket and engages the catch at a location offset from its pivot axis relative to the bracket. Upon displacement of the cable, the catch is actuated out of engagement with the sector, resulting in the headrest support pivoting relative to the seatback.
