A self-propelled motorized infant stroller powered by DC electric motors with safely controlled acceleration and deceleration. As a discrete safety function, the controlled acceleration and deceleration prevents the child occupant from lurching, either forward or backward, upon the starting or stopping of the baby carriage. A single speed control dial establishes the setting of the desired traversing speed. The propulsion system is safely controlled through the use of a set of dual handle switches that both must be simultaneously depressed to start the propulsion system. A safety seat harness is used to protect the infant occupant from sliding or climbing out of the carriage seat. Additional safety is provided by a parking brake system to prevent accidental propulsion or any unforeseen stroller movement, particularly when stopped on an inclined surface.

[ I claim:] [1.] A self-propelled infant stroller comprising:a frame assembly formed by a plurality of tubular shafts, the frame assembly including a handle;a plurality of wheels mounted on the frame assembly with at least one of the wheels being a driven wheel;a propulsion control system including a control console housing mounted on said handle;a single, hand operated control lever mounted to the frame adjacent the driven wheel for pivotal movement between first and second positions relative to the driven wheel;a drive motor mounted on the control lever, said drive motor having an output shaft with a drive gear extending from one side of said control lever, and said drive motor being controlled by said propulsion control system;a brake member extending from an opposite side of the control lever, said brake member being selectively engageable with a braking surface on the driven wheel;a driven gear mounted on the driven wheel, said shaft drive gear being selectively engagable with said driven gear; and,means for selectively securing the control lever in the first position in which the drive gear is in driving engagement with the driven gear and the brake member is disengaged from the braking surface for propelling the stroller, and in the second position in which the drive gear is disengaged from the driven gear and the brake member is engaged with the braking surface for preventing rolling movement of the stroller.
