Abstract: A foldable car seat carriage includes a frame unit and an engagement unit. The frame unit includes two leg frames. Each of the leg frames includes two legs pivotable relative to each other, and a driving mechanism. The driving mechanism has opposite ends connected pivotally to the legs at first and second intersections. The engagement unit includes two bayonets.

Abstract: A child stroller apparatus includes a rear and a front leg frame respectively having a first and a second side segment, a handle frame having a grip portion and a third side segment respectively connected fixedly with a first and a second joining part that are pivotally connected with each other, a latching mechanism for locking the rear and front leg frames and the handle frame in an unfolded state, and a latch carried with the third side segment. The latch can engage and disengage the first joining part to lock and unlock the grip portion relative to the third side segment. Moreover, a linking part couples the latch to the rear leg frame or the front leg frame so that a folding rotation of the handle frame relative to the rear leg frame causes the latch to disengage from the first joining part.
