ABSTRACT:
A collapsible high chair includes a pair of front legs (14) pivotally connected by pivot pins (13) to a pair of backrest holding rods (6) which hold a backrest (3), whereby an upper end portion of each front leg (14) overlaps a lower end portion of the associated backrest holding rod (6). Two rear legs (16) are pivotally connected respectively to the lower ends of the backrest holding rods (6) by pivot pins (15). The backrest holding rods (6) are pivotally connected at their intermediate portions to the rear portion of a seat (2) by pivot pins (5). Two seat support rods (20) are operatively connected between the front portion of the seat (2) and the front legs (14). When the lower ends of the backrest holding rods (6) are moved away from the front legs (14), the backrest holding rods (6), seat (2), front legs (14) and rear legs (16) assume a substantially horizontal state. In this manner, the chair can be folded for reducing its dimension in the direction of its height.
