<p>An adjustable seat back has side sections that fold inward to provide lateral support for an infant or remain flat to provide a wider seat back for a toddler. The seat back includes a center portion (180) and two side wing sections (185) that are pivotal with respect to the center section about substantialy vertical axes along two seams. A wing adjustment assembly (200) sewn into a section of the seat liner (100) includes a pivoting actuator (300). By actuation of the lever section (310) of the actuator that extends through an aperture (240) in the liner at the rear of the seat back, the operator can pivot a pair of wing support sections (360) outward on the front side of the liner. The wing support sections of the actuator act to push the two wing sections of the seat pad forward providing a narrower seat to provide lateral support for an infant.</p> |
