A vehicle headrest assembly includes a latch mechanism moveable between an engaged position and a release position. The vehicle headrest assembly also includes a shape memory alloy (SMA) release assembly operatively coupled to the latch mechanism to selectively move the latch mechanism from the engaged position to the release position. The SMA release assembly includes an actuator base including a pair of tracks defining a slot, the actuator base including a plurality of retaining tabs. The SMA release assembly also includes a printed circuit board (PCB) retained directly to the actuator base and disposed adjacent the plurality of retaining tabs. The SMA release assembly further includes a slide disposed within the slot and retained to the actuator base with the pair of tracks. The slide is moveable to contact and bias the latch mechanism to the release position upon energization and contraction of a SMA wire.
