US Patent 7066542 Child high chair with an inclination adjustable backrest

A child high chair includes a seat body disposed between two side guarding members on an upper portion of a support leg, a backrest unit having two lateral ends pivotally coupled to the side guarding members to be turnable relative thereto, two bolts disposed movably on the lateral ends in a longitudinal direction, an actuator movably disposed on the backrest unit in an upright direction, and two flexible members interconnecting the actuator and the bolts such that when the actuator is moved from a lower position to an upper position, the flexible members are pulled to move the bolts in the longitudinal direction from an extended position where the bolts engage retaining members on the side guarding members to a retracted position where the bolts disengage from the retaining members so as to permit turning of the backrest unit relative to the seat body.
