Abstract

A juvenile vehicle seat includes a base, a seat back, and a width controller. The base includes a seat bottom and first and second armrests mounted for pivotable movement on opposite sides of the seat bottom. The width controller can be operated to cause the first and second armrests to pivot relative to one another and to the seat bottom.

Dependent claims

A juvenile vehicle seat comprising

a base including a seat bottom, a first armrest mounted on the seat bottom for pivotable movement about a first Y-axis toward and away from the seat bottom, and a second armrest mounted on the seat bottom for pivotable movement about a second Y-axis toward and away from the seat bottom, a seating surface provided on the seat bottom being arranged to lie between the first and second armrests,
a seat back including a backrest arranged to extend upwardly from the seat bottom, a first side wing mounted on the backrest for pivotable movement about a first Z-axis toward and away from the backrest, and a second side wing mounted on the backrest for pivotable movement about a second Z-axis toward and away from the backrest, the backrest being arranged to lie between the first and second side wings, and
a width controller configured to include
base-changer means for pivoting the first and second armrests in unison relative to the seat bottom, respectively, about the first and second Y-axes, at the option of a caregiver, to change an effective width of the base on the seating surface and between the first and second armrests to cause one of (1) the first and second armrests to pivot in unison toward one another to establish a relatively narrow narrow-width base dimension and (2) the first and second armrests to pivot in unison away from one another to change the effective width of the seat base from a narrow-width base dimension to a relatively wider expanded-width base dimension so that the effective with of the seat base is adjusted to match size characteristics of a child to be seated on the seating surface of the seat bottom and between the first and second arms and
back-changer means coupled to the base-changer means for pivoting the first and second side wings in unison relative to the backrest, respectively about the first and second Z-axes, in response to pivoting movement of the first and second armrests to change an effective width of the seat back on the backrest and between the first and second side wings to cause one of (1) the first and second side wings to pivot in unison toward one another to establish a relatively narrow narrow-width back dimension when the first and second armrests are pivoted toward one another and (2) the first and second side wings to pivot in unison away from one another to change the effective width of the seat back from a narrow-width back dimension to a relatively wider expanded-width back dimension so that the effective width of the seat back is adjusted during adjustment of the effective width of the base to match size characteristics of the child to be seated on the seating surface of the seat bottom.
