ABSTRACT:
A chair device for a person carrier includes a backrest unit formed by a front backrest and a rear backrest. The backrest unit is pivotally joined to a seat unit in which two opposite fan-shaped limit projecting members are provided at each pivot-joint end of the seat unit. The fan-shaped limit projecting members can be angularly displaced to a position to be engaged with fan-shaped recesses in the pivot-joint ends of the rear backrest. The fan-shaped limit projecting members have a position limited space for angular displacement within the fan-shaped recesses so that the backrest unit of the chair can move in the range between a collapsing state and an unfolding state. Furthermore, strength reinforcing edge ribs are provided at both sides where the front backrest is assembled to the rear backrest.
