Abstract
A backrest recline adjustment assembly includes a stationary seat, a rotary seat, and a driving component. The stationary seat is connected to a stroller frame, and is provided with a first positioning unit. The rotary seat is connected to a backrest unit and has a second positioning unit, a groove formed thereon, and a first cam surface formed in the groove. The driving component is disposed in the groove of the rotary seat and provided with a second cam surface. The driving component is movable to drive sliding movement of the second cam surface relative to the first cam surface, thereby moving the rotary seat against biasing action of a resilient component from a securing position, where the rotary seat is positioned relative to the stationary seat, to a releasing position, where the rotary seat is rotatable relative to the stationary seat.
