B.TECH MECHANICAL ENGINEERING SEMINAR

WHIPLASH PROTECTION SYSTEM

ABSTRACT

Whiplash Protection System (WHIPS) is designed to help protect occupants in the event of a rear-end collision.  It can be concluded that seats aimed at preventing whiplash injuries in general also lower the risk in real-life crashes. Furthermore it can be concluded that results from existing consumer crash test programs for whiplash correlate with real life injury outcome. WHIPS equipped seat, the entire backrest is designed to help protect the front occupant's neck in a case of a rear impact. WHIPS equipped seats have a piece of metal inside the backrest that absorbs energy in case of rear end collision, reclining the headrest a few centimeters. The metal piece should be replaced later. Used in Volvo vehicles since 1994. The seat, which has new design concept for reduction in whiplash injuries, allows less motion between head and torso in the modified dummy sled tests, and also allows less motion in volunteer sled tests. Moreover there is less movement between each cervical vertebra. Cars fitted with advanced whiplash protection systems had 50% lower risk of whiplash injuries leading to long-term symptoms compared with standard seats launched after 1997. The seminar covers the major whiplash protection systems such as Reactive Head restraints, proactive head restraints, inflatable head restraints and reactive seats.
