Abstract
An automotive head restraint apparatus includes a housing having a padded and upholstered exterior, the housing being rotatable about a lateral support tube that supports a lock plate having a lobe extending radially with a detent slot extending therein. A latch finger extends from a pivotable lock lever plate to releasably engage in the detent slot to latch the housing in the deployed position. A pull rod is secured to the lock lever plate, and is connected to a release lever arm at its other end. A shape memory alloy (SMA) wire loop is passed about a drive pulley that is supported by a reciprocally translatable slide. A drive arm extends from the slide to impinge on the release lever and raise the pull rod when the SMA wire loop is energized and contracted, thereby releasing the latch finger to rotate the housing to the retracted position.
