A child safety harness assembly for securing a child in a vehicle includes a first strap that has a midsection. The midsection is curved, such that opposing side sections of the strap extend in substantial parallelism from the midsection. Each of a pair of second straps is coupled to and extends between the opposing side sections. The second straps are substantially evenly spaced between the midsection and opposing ends of the first strap. A third strap has a first endpoint that is coupled to the midsection equally distant from the opposing ends of the first strap. Each of a set of three couplers is coupled singly to the opposing ends and the third strap. The second straps and the third strap are length adjustable. The couplers are configured to couple to anchors of the vehicle to couple the child to the vehicle.
