Abstract:
1. A child restraint comprising an adjustable base including a cradle support adapted to set on a passenger seat in a vehicle, a tiltable carrier cradle mounted on the cradle support for pivotable movement about a pivot axis relative to the cradle support to change angular orientation of the tiltable carrier cradle relative to the cradle support, and a tilt controller coupled to the tiltable carrier cradle and to the cradle support, a detachable infant carrier configured to mate temporarily with the tiltable carrier cradle and move therewith relative to the cradle support during pivotable movement of the tiltable carrier cradle about the pivot axis, wherein the tilt controller includes a cradle-orientation changer comprising a rotatable actuator mounted on the cradle support for rotation about an axis of rotation and a cradle elevator coupled to the tiltable carrier cradle and to the rotatable actuator and configured to pivot the tiltable carrier cradle about the pivot axis in response to rotation of the rotatable actuator about the axis of rotation, wherein the cradle support is formed to include an interior region and an actuator-receiver aperture opening into the interior region and the rotatable actuator includes an interior section located in the interior region of the cradle support and engaged to the cradle elevator and an exterior section coupled to the interior section and arranged to extend through the actuator-receiver aperture and provide a terminal end lying outside the interior region, wherein the interior section of the rotatable actuator includes elevator-mover means for moving the cradle elevator relative to the cradle support to cause the tiltable carrier cradle to pivot about the pivot axis in response to rotation of the rotatable actuator about the axis of rotation caused by a torque applied to the exterior section of the rotatable actuator so that the angular orientation of the tiltable carrier cradle relative to the cradle support is changed, and wherein the elevator-mover means is a worm, the cradle elevator includes a cradle-mover rod mounted for sliding movement in a cradle-pivot channel formed in the tiltable carrier cradle between a first position wherein the tiltable carrier cradle is arranged to lie in an initial position relative to cradle support and a second position wherein the tiltable carrier cradle is arranged to lie in a first tilted position relative to the cradle support, and the cradle elevator further includes a rod-mover block coupled to the cradle-mover rod and formed to include a worm gear mating with the worm to establish worm-drive means for moving the rod-mover block along the axis of rotation to cause the cradle-mover rod to move in the cradle-pivot channel between the first and second positions in response to rotation of the rotatable actuator about the axis of rotation so that the angular orientation of the tiltable carrier cradle relative to the cradle support is changed.
