Child restraint headrest with side-wing mover

A child restraint comprising

• a seat bottom and
• a seat back including a backrest arranged to extend upwardly from the seat bottom and a head receiver coupled to the backrest and arranged to lie above the seat bottom,
• wherein the head receiver comprises an adjustable-width headrest and a headrest-width changer, the adjustable-width headrest includes a center head support associated with the backrest, a first movable head support mounted on one side of the center head support for lateral sliding movement relative to the center head support, and a second movable head support mounted on an opposite side of the center head support for lateral sliding movement relative to the center head support, and headrest-width changer includes converter means for moving the first and second movable head supports away from one another to provide a large head-receiving space between the first and second movable head supports and establish a wide mode of the adjustable-width headrest and toward one another to provide a relatively smaller head-receiving space between the first and second movable head supports in response to movement of one of the movable head supports away from the center head support to establish a narrow mode of the adjustable-width headrest,
• wherein the headrest-width changer includes a linear motion converter and a motion-converter lock,
• wherein the linear motion converter comprises a first rack strip cantilevered to the first movable head support and arranged to extend toward the second movable head support and a second rack strip cantilevered to the second movable head support and arranged to extend away from the second movable head support, the second rack strip is arranged to lie in spaced-apart parallel relation to the first rack strip to define a gear-receiving space therebetween, the linear motion converter also includes a motion-transfer gear that is arranged to extend into the gear-receiving space to engage and mesh with teeth included in each of the first and second rack strips, the motion-transfer gear rotates about an axis of rotation to convert linear motion of one of the rack strips automatically into linear motion of the other of the rack strips so that movement of one of the movable head supports relative to the center head support results in movement of the other of the head supports relative to the center head support to widen or narrow the adjustable-width headrest, and
• wherein the motion-converter lock interacts with the motion-transfer gear of the linear motion converter and can be used by a caregiver to block any mode change of the adjustable-width headrest between narrow and wide modes, the motion-converter lock is mounted on the center head support for up-and-down movement between a locked position in which rotation of the motion-transfer gear about its axis of rotation is blocked so that the adjustable-width headrest cannot be widened or narrowed and an unlocked position in which the motion-transfer gear is free to rotate about its axis of rotation to allow the caregiver to widen or narrow the adjustable-width headrest by moving one of the movable head supports relative to the center head support.
