Child car seat device with wing components

Abstract

A child car seat device with wing components includes a seat assembly, a backrest assembly and a headrest assembly, which are connected each other. The headrest assembly includes a headrest body, two headrest wing components, and two pivots passing through the headrest body and headrest wing components. Each pivot is retained by a fastener or a tab extending from the headrest wing component. The headrest body has a plurality of grooves and the headrest wing component has a rib. An angle defined between the headrest wing component and the headrest body can be changed by engaging the rib within different grooves. The headrest body has a stopper so that the headrest wing component cannot be pivotally rotated further outwards when it abuts against the stopper. The structures of the backrest assembly are similar to those of the headrest assembly. In addition, the seat device may be provided with the headrest wing components and/or backrest wing components.
