Abstract
The function of the head restraint system is to prevent injurious hyperextension of the neck following a vehicle rear end impact. The nature and severity of the head and neck injuries attributed to rear end impacts are the result of many factors including the manner in which the head is supported throughout the impact process. A well-designed head restraining system will prevent neck hyperextension and accomplish this with the minimum risk of consequential injury to the head. Also, it must not present a safety hazard in itself and its effectiveness should not depend on precise adjustment. This paper discusses the approach taken in the design and development of a low impact airbag head restraint system.
