improvements in occupant restraint usage. Two of the national seat belt usage rates for drivers of passenger vehicles increased from % in to % in -- a percentage increase of about 24 % and very close to each of the three occupant injury severity levels can be derived.

The use of seat-belts and child restraints is one of the most important actions that can be taken to prevent injury in a motor vehicle crash. While seat-belts and child restraints do not prevent crashes from taking place, they play a major role in reducing the severity of injury to vehicle occupants involved in a collision. An occupant’s.

Background. Currently, many states are upgrading their child restraint laws to include provisions for the use of age-appropriate restraints through 6 to 8 years of age, with some also requiring rear seating for children, enabling the laws to be in closer alignment with best-practice recommendations. Objective. To evaluate the relationships of seating position and restraint status to the risk. combined head and chest injury. Keywords: Restraint performance, ridedown efficiency, restraint quotient, injury risk INTRODUCTION Occupant restraints, such as seatbelts and airbags, are used to reduce the potential for injury in automobile crashes. The effectiveness of these devices for reducing occupant injury in real-world crashes has been well.

Restraint use. Restraint use was dichotomized as: 1) not belted; and 2) belted (shoulder belt, lap belt, shoulder and/or lap belt). Driver alcohol involved.

The driver was considered to have alcohol present if police reported alcohol or the driver had a blood alcohol concentration (BAC) of or higher. Injury by: 2. Recent findings from a University of Kentucky College of Public Health study indicate that the lack of a safety restraint is the main factor in injury severity to truck drivers and passengers in commercial vehicle crashes – rather than the location of drivers and passengers within the cab.

Occupant/Person Information on drivers and injured persons in a crash: age, gender, restraint use, seating position, injury severity, airbag deployment, and motorcyclist specific.

These Data are Not Live. Effects of Head Restraint and Vehicle Damage Severity on Neck Injury Risk. This article reports on a study in which domestic automobile insurance claims were investigated to correlate the driver neck injury risk with the safety rating of the head restraint, the severity of.

Objective: Unbelted occupants may increase the risk of injury for other occupants in a motor vehicle collision (MVC). This study evaluated the association between occupant restraint use and the risk of injury (including death) to other vehicle occupants. Design: A population based cohort study.

Setting: United States. Subjects: MVC occupants (n = unweighted, n = 18 weighted Cited by:   In all modeling efforts, the dependent variable is severity, usually depicted on a 3- or 4-point ordinal scale (e.g. no injury, severe injury, and fatal).

The unit of analysis varies across studies and depends on the objective; units include, for example. non-motorized road users (pedestrians and/or bicyclists) (Ballesteros et al.,Kim et al.,Lee and Abdel-Aty,Sze and Wong. codification, crash configuration, restraint usage, rollover crash orientation, ejection status, injured body region groupings, injury severity, and occupant counts versus injury counts.

Occupant Selection As described in previous works, occupancy rates of the various vehicle platforms dictated the selection of drivers.

The risk of sustaining injury in frontal collisions is correlated to collision severity as well as other factors such as restraint usage and airbag deployment. Eleven years ( to ) of National Automotive Sampling System (NASS) data from the Crashworthiness Data System (CDS) were analyzed to i.

Multivariate regression analysis showed that drivers of youth between 4 and 14 years were in need of programs promoting youth and driver occupant restraint use. When these drivers were using seat belts, it was 35 times more likely they had youth occupants in safety restraints. A focus on pickup truck drivers may also give these programs greater.

Objective: Vehicle change in velocity (delta-v) is a widely used crash severity metric used to estimate occupant injury risk.

Despite its widespread use, delta-v has several limitations. Of most concern, delta-v is a vehicle-based metric which does not consider the crash pulse or the performance of occupant restraints, e.g.

seatbelts and airbags. Travel speed, restraint device usage, point of impact, use of alcohol and drugs, personal condition, gender, whether the driver is at fault, urban/rural nature and grade/curve existence at the crash location were identified as the important factors for making an injury severity difference to older drivers involved in single vehicle crashes.

Comparison of Vehicle Structure and Occupant Responses in Driver‐ and Passenger‐Side IIHS Small Overlap Frontal Crash Tests. Front crashworthiness evaluations by the Insurance Institute for Highway Safety include driver (left) side small overlap (25%) frontal crash tests at 64 km/h with a rigid, radius‐edged flat barrier.

Injury Prevention ;– doi: /ip Objective: Unbelted occupants may increase the risk of injury for other occupants in a motor vehicle collision (MVC).

This study evaluated the association between occupant restraint use and the risk of injury. For each restraint configuration, contact rates are compared by three categories of injury severity, AIS 1, AIS 2, and AISbody region injured, and contact area producing the injury.

The three-point belt provides substantial reductions in driver injury rates for head/face and torso contacts with the glazing, pillar/rails, and steering. Chart Driver Injury Rates perLicensed Drivers in by Age and Gender Chart Driver Fatalities, to Year-Olds, by Restraint Use When Known.

14 National Highway Tra(c Safety Administration 1. Most drivers and passengers killed in crashes are unrestrained. 53% of drivers and passengers killed in car crashes in were not wearing restraints.

1; Seat belts dramatically reduce risk of death and serious injury. Among drivers and front-seat passengers, seat belts reduce the risk of death by 45%, and cut the risk of serious injury by 50%. In France, Lamielle et al. [], used in depth crash data to examine the effect of restraint type, crash severity and occupant seating position on abdominal injury study covered.

„injury caused by restraint system“ does not mean that the injury risk would be lower without restraint system but that it can be expected that the injury severity could be reduced by improvements of the restraint system or the cabin pulse.
