An enhanced head-and-neck restraint system is provided for use with a vehicle having a passenger compartment with a seat assembly and a safety belt assembly mounted therein. The restraint system includes first and second collar straps each having an inflatable cushion integrated thereto. A first end of each collar strap is attached to a headrest portion of the seat assembly to transition between a retracted position, in which the collar straps are substantially inside the headrest portion, and a use position, in which each collar strap attaches to a belt webbing of the safety belt system. A fluid dispensing apparatus is in fluid communication with the inflatable cushions, and operable to selectively transition the inflatable cushions from a non-expanded state to an expanded state when the collar straps are in the use position.
