Claim:
A child high chair comprising: a support leg having a lower portion and an upper portion opposite to each other in an upright direction; a mounting seat including left and right side guarding members which are opposite to each other in a longitudinal direction transverse to the upright direction and which are secured on said upper portion of said support leg; a seat body which is disposed between said left and right side guarding members, and having front and rear seat portions opposite to each other in a transverse direction relative to both the longitudinal direction and the upright direction; a backrest unit having left and right lateral ends which are opposite to each other in the longitudinal direction, and which are respectively inboard to said left and right side guarding members, and a middle backrest portion which is disposed between said left and right lateral ends and which has front and rear walls opposite to each other in the transverse direction, each of said left and right lateral ends being pivotally coupled to a respective one of said left and right side guarding members adjacent to said rear seat portion of said seat body to permit said backrest unit to turn about a pivot axis in the longitudinal direction; a plurality of left retaining members which are in a form of a plurality of holes that are formed in said left guarding member, and which are angularly displaced from one another about the pivot axis, a plurality of right retaining members which are in a form of a plurality of holes that are formed in said right side guarding member, and which are angularly displaced from one another about the pivot axis; a pair of bolts, each of which is disposed on and which is movable relative to a respective one of said left and right lateral ends in the longitudinal direction between an extended position, where a respective one of said bolts engages a selected one of said left and right retaining members so as to prevent turning of said backrest unit, and a retracted position, where the respective one of said bolts disengages from any one of said left and right retaining members so as to permit turning of said backrest unit about the pivot axis; an actuator which is disposed on and which is movable relative to said rear wall of said middle backrest portion in the upright direction; a pair of flexible members, each of which has a first end that is connected to said actuator, and a second end that is connected to a respective one of said bolts, and each of which is configured such that when said actuator is moved in the upright direction from a lower position to an upper position, said flexible members are pulled to move said bolts in the longitudinal direction from the extended position to the retracted position; and a biasing member disposed to bias said actuator toward the lower position.
