Rear Seat Occupant Protection in Frontal Crashes and Its Feasibility

  title={Rear Seat Occupant Protection in Frontal Crashes and Its Feasibility},
  author={Richard W. Kent and Jason Forman and Daniel P. Parent and Shashi M Kuppa},
As part of the National Highway Traffic Safety Administration's (NHTSA's) Rear Seat Occupant Protection Research Program, the Fatality Analysis Reporting System (FARS) and State Data System (SDS) for Florida, Pennsylvania and Maryland were utilized to estimate relative fatality rates and injury risk ratios between the front and rear seat passengers. In addition, a parametric study of rear-seat restraint parameters was performed to assess chest deflection and head excursion trends for different… 

Real World Analysis of Rear Seat Occupant Safety in Frontal Crashes

This review suggests that in the absence of overly severe frontal crash conditions and vulnerabilities due to advanced age, properly belted adults and children in age- and stature-appropriate child restraints are reasonably well-protected in the rear seat, although improvements could be achieved in some cases.

Optimizing Seat Belt and Airbag Designs for Rear Seat Occupant Protection in Frontal Crashes.

This study highlighted the potential benefit of using advanced seatbelt and airbag systems for rear-seat occupant protection in frontal crashes by optimizing advanced restraint systems for protecting rear seat occupants with a range of body sizes under different frontal crash pulses.

Differential Fatality Risk Between Rear and Front Seat Passenger Vehicle Occupants in Frontal Crashes

Popular wisdom has long suggested that rear seated occupants are better protected than front seat occupants in the event of a frontal crash. However, relatively recent studies have begun suggesting

Front versus Rear Seat Injury Risk for Child Passengers: Evaluation of Newer Model Year Vehicles

This analysis, conducted on a set of vehicles with advanced front seat safety systems including second-generation and newer air bags, strongly confirmed the recommendation that all children 0–12 years should be seated in the rear row(s) of their vehicles.

Occupant restraint in the rear seat: ATD responses to standard and pre-tensioning, force-limiting belt restraints.

The results suggest that the FL+PT system studied here may provide injury-reducing benefit to rear seat occupants in moderate to high severity frontal crashes, although more study is needed to evaluate these restraints in other crash scenarios.

Rear Seat Safety in Frontal to Side Impacts - Focusing on Occupants from 3yrs to Small Adults

ABSTRACT This study presents a broad comprehensive research effort that combines expertise from industry and academia and uses various methodologies with applied research directed towards

Assessment of Vehicle and Restraint Design Changes for Mitigating Rear Seat Occupant Injuries

The results from this study demonstrate the importance of an upright seated posture and the potential benefits of including adjustable upper anchorages to allow good sash belt fit, antisubmarining seat pans, belt buckles positioned near the seat bight, and seat belts with pretensioners and load limiters for rear seat occupants.

A Simulation Study on the Efficacy of Advanced Belt Restraints to Mitigate the Effects of Obesity for Rear-Seat Occupant Protection in Frontal Crashes

The simulation results suggest that optimizing load limiter and adding pretensioner(s) can reduce injury risks associated with obesity, but conflicting effects on head and chest injuries were observed.



Rear seat occupant protection in frontal crashes

Though a significant body of literature exists on the safety performance and effectiveness of various types of front seat occupant restraint systems, there is a paucity of data on the performance of

Thoracic Injury Risk in Frontal Car Crashes with Occupant Restrained with Belt Load Limiter

In France and in other countries, research shows that the highest proportion of severe injuries and fatalities to restrained occupants occurs in frontal impacts. The oldest occupants involved in

Comparison of Thoracic Injury Risk in Frontal Car Crashes for Occupant Restrained without Belt Load Limiters and Those Restrained with 6 kN and 4 kN Belt Load Limiters.

This paper reports on 347 real-world frontal accidents and compares the thoracic injury risk for two occupant populations: belted occupants involved in accidents in which the vehicle was not equipped with a load limiter (378 cases with pyrotechnic pretensioners), and belted occupant populations involved in incidents where the vehicles were equipped with 4 or 6 kN load limiters and pyrotehnic Pretensioners (347 cases).

New Car Assessment Program (NCAP) test scores, measured by the United States Department of Transportation's (USDOT) National Highway Traffic Safety Administration (NHTSA), were analyzed in order to

Laboratory Reconstructions of Real World Frontal Crash Configurations using the Hybrid III and THOR Dummies and PMHS.

The test methodology and the results used to evaluate dummy ability to discriminate both restraint types and dummy measurement ability to be representative of thoracic injury risk for all restraint types are presented.

The Effects of Vehicle Seat Belt Parameters on the Injury Risk for Children in Booster Seats

The development of a multi-body model of an appropriate child restraint system proves to be useful for the evaluation of various existing seat belt restraint systems and their effect in the injury


The 3-point static belts that are installed in Renault and Peugeot vehicles are equipped with a force limiter near the upper anchorage and the levels of tolerance observed in this sample are compared to thoracic injuries observed on belted cadavers exposed to equivalent violent impacts.

The influence of superficial soft tissues and restraint condition on thoracic skeletal injury prediction.

Externally measured chest compression is shown to correspond well with the presence of hard tissue injury, regardless of restraint condition, and rib fracture onset is found to occur at approximately 25% chest compression.

Development of an Improved Thoracic Injury Criterion

A linear combination of the 3-msec clip value of maximum resultant spine acceleration and maximum normalized chest deflection from an array of five measurements provided the goodness of fit measure and was found to have significantly better injury predictive ability, for thoracic trauma in human subjects under any restraint environment, than other existing injury criteria.
