Download or read book Role of the Seat in Rear Crash Safety written by David C Viano and published by SAE International. This book was released on 2002-10-25 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Role of the Seat in Rear Crash Safety addresses the historic debate over seatback stiffness, energy absorbing yielding, occupant retention and whiplash prevention; and it provides a scientific foundation for the direction GM pursued in the development and validation of future seat designs. It also describes the multi-year research study into the role of the seat in rear crash safety - first by addressing the need for occupant retention in the more severe rear crashes; and then by addressing the needs for an adequately positioned head restraint and changes in the compliance of the seatback to lower the risks of the whiplash in low-speed crashes.

Available in PDF, EPUB and Kindle. Book excerpt: Automotive rear impacts are the most common type of car accident, with 2.5 million occuring each year. Most often, the vehicle property damage is minor with no occupant injury. However, more serious rear-end collisions can result in life-changing events. There are two major injury types caused by rear impact accidents. Whiplash (non-lethal injury) and Seat-Collapse (potential serious or lethal injury). Driver and front passenger seats all too often fail, with the seatback collapsing, ejecting the occupants rearward into the rear seat area with serious consequences. Seat design strength requiements are covered by FMVSS 207 Seat Systems Standard. The auto companies rely on this standard to test their seatsdard. The FMVSS 207 standard for seatback strength is flawed auto compaies use this requirement to allow the seatback to deform during a serious rear-impact, to achive enery-management. The controversy over seatback strength, Rigid verus Yielding, continues today. An occupied front seat that collapses during a rear-impact can entrap rear seat occupants, especially children that are required to sit in the rear row seats. Safety advocates and researchers report that for the period 1990 to 2014 nearly 900 children seated behind a front-seated occupant or in a center rear seat died in rear impacts of 1990 and later model-year cars. Law suites are prevalent and multi-million dollar penalties or settlements resulted and litigation continue today. Rear-end crashes also involve vehicle occupants in other automotive design hazards. Use of Child Restraints (CRS) is essentaial.

Available in PDF, EPUB and Kindle. Book excerpt: Pediatric fatality rates from motor vehicle crashes (MVCs) have declined over the last 30 years (National Highway Traffic Safety Administration, 2012). This decrease can be a result of updated traffic safety laws and improved car seat design. These advancements present the opportunity to shift focus towards understanding and improving safety for non-fatal injuries. One study found crashes resulting in clinically significant injury (AIS 2+) to children, the lower extremity (LE) was the most frequently injured body region, resulting in 28% of injuries (Arbogast et al., 2002). Jermakian et al. (2007) found in a review of crash data involving a rear-seated child in a front facing child restraint system (FFCRS) whom experienced lower extremity fracture, 76% of injuries occurred below knee (20/26), where 75% (15/20) of the below knees injuries were a consequence of interaction with the front seat back, regardless of the direction of impact. Research completed by the Injury Biomechanics Research Center at The Ohio State University has worked to develop an instrumented LE for the Hybrid III six-year-old anthropomorphic test device (ATD). This modified LE incorporates 6-axis load cells in each tibia and ROM stops to improve ankle biofidelity. This updated LE design was used to investigate the effect of front seat back (FSB) properties, initial leg position, and rear compartment geometries in eight 30 mph frontal impact tests. The FSB properties were designed to mimic the two extreme conditions: impacting a rigid or soft anterior structure. The rear compartment space was adjusted to represent a front seat forward or closer toward the LE of the ATD. Initial positioning of the LE either initially touching the FSB or relaxed was another variable investigated. Tibia force and moment, femur forces, tibia index, excursion distance, and head injury criterion were all parameters examined. Data suggest that when the LE was initially touching a stiff FSB, values were observed that either approached or exceeded injury thresholds. When the LE was initially touching a foam FSB, no injurious values were observed. In all four tests when the LE was initially relaxed, independent of front seat positon, the LE impacted the lower rigid portion of the front seat resulting in values that either approached or exceeded injury thresholds. The ATD-LE was successfully used in frontal impact tests, but improvements can be made to the ankle biofidelity at high speeds in both dorsiflexion and plantarflexion. These data can be used to update front seat properties to improve LE protection and present the value of utilizing an instrumented HII6YO ATD-LE.
