METHODS, APPARATUS AND SYSTEMS FOR SECURING AN INFANT CAR SEAT TO A VEHICLE SEAT WITH A TIGHT FIT AND WITHOUT USING A DETACHABLE VEHICLE INSTALLATION BASE OR A VEHICLE SEAT BELT, AND RIDE-HAILING METHODS RELATING TO SAME

An infant car seat system includes an infant car seat with an integrated anchor system to conveniently secure the infant car seat to a vehicle seat, without using a detachable vehicle installation base and without using a vehicle seat belt. The anchor system is coupled to the infant car seat at one or more mechanical constraining points positioned based on the center of gravity of the infant car seat and respective anchor points at which the anchor system engages with vehicle lower anchors. The anchor system may be a rigid anchor system or a belted anchor system, and the system may include one or more of a release actuator for a quick disconnect mechanism, an adjustment foot to accommodate different vehicle seats and ensure a tight fit, and/or one or more storage compartments to store parts of the anchor system when unused.
