A bi-directionally convertible infant car-seat/stroller in which the conversion is effected by operating a single pushbutton which is mechanically coupled to a pair of pawls on opposite sides of the car-seat/stroller, such pawls engaging respective detents in discs or drums rotatably supported from the frame of the apparatus on opposite sides of the apparatus until withdrawn against the force of respective return-spring by the operator\s actuation of a single control button which is mechanically coupled by means of flexible cables or rods to such pawls and causes such withdrawal when desired, the result of such withdrawal being the enabling of the movement of the front and rear wheel assemblies of the car-seat/stroller from an extended to a folded position and vice versa as result of the coupling of pivot arms carrying the front and rear wheel assemblies being rotatable with the disc when the pawl associated with each disc is withdrawn from the detent in the disc, as a result of which the apparatus can be converted from an infant car-seat to an infant stroller and locked in those positions without fear of danger to the infant resulting from the collapsing of the car-seat/stroller from the desired mode accidentally. The invention further provides a mechanism for adjusting and holding the handle of the car-seat/stroller in discrete, predetermined positions and selectively applying braking when in the stroller mode.
