  • Technical Paper
  • 2019-28-2457
Published 2019-11-21 by SAE International in United States
M. Priyanka, Mahindra & Mahindra, India Sai Himaja Nadimpalli , Mahindra & Mahindra, India Keywords-Safety, Connectivity, GPS Research and/or Engineering Questions/Objective: There are many times the driver or co-passenger can experience emergency conditions whenever the vehicle is running or it is in static. These kind of situations are tough to handle even if one is victimized . The victim can be rescued on time if proper information about the situation would reach his friends or family . Limitations: In existing system, if the accidental crash happens then signal from airbag unit will wake up the mobile, Once this wake up call happens,it will activate the gsm module. The emergency contacts stored in the mobile will be dialed up and the victim can convey his emergency situation through that. The driver will be rescued only if crash happens. There is no system to rescue the driver if heart attack happens when he is driving. The additional problem which the system has is emergency contact is out of town,the victim will not be rescued Methodology: In order…

FOUR WAY ADJUSTABLE HEAD RESTRAINT SYSTEM

Academic Center-Nitin Kumar Waghmare
  • Technical Paper
  • 2019-28-2528
Published 2019-11-21 by SAE International in United States
To reduce the incidence of whiplash-associated disorders caused by rear impacts, head restraints should be closer to the head which decreases the amount of relative motion and it is believed to reduce the risk of soft tissue neck injury. Drivers are raising complaints that the head restraint causes discomfort by interfering with their preferred head position, forcing them to select a more reclined seat back angle [1]. This paper is about the importance of head restraint system and how it can be improved by adjusting the angle between the head restraint and passenger`s head. It is essential to carry out research on head restraint that can be adjusted in forward and backward direction letting the cost of seats remain in budget.

Performance Standard for Child Restraint Systems in Transport Category Airplanes

Aircraft SEAT Committee
  • Aerospace Standard
  • AS5276/1
  • Current
Published 2019-10-31 by SAE International in United States
This SAE Aerospace Standard (AS) defines minimum performance standards and related qualification criteria for add-on child restraint systems (CRS) which provide protection for small children in passenger seats of transport category airplanes. The AS is not intended to provide design criteria that could be met only by an aircraft-specific CRS. The goal of this standard is to achieve child-occupant protection by specifying a dynamic test method and evaluation criteria for the performance of CRS under emergency landing conditions.

Motor Vehicle Seating Systems

Motor Vehicle Council
  • Ground Vehicle Standard
  • J879B_201910
  • Current
Published 2019-10-02 by SAE International in United States
This SAE Recommended Practice establishes uniform test procedures and certain minimum performance requirements for motor vehicle seats and seat adjusters. It is limited to tests that can be conducted on uniform test fixtures and equipment available in commercial laboratory test facilities. This practice includes a minimum requirement for horizontal forward loads encountered in vehicle forward impacts, and horizontal loads obtained by impacting the vehicle from the rear. The requirements and test procedures in this recommended practice reflect current technology and industry experience. It is intended to subject this recommended practice to a continuing review and revision as technology advances and experience is expanded.

Crewmember Demand Oxygen Mask for Transport Category Aircraft

A-10 Aircraft Oxygen Equipment Committee
  • Aerospace Standard
  • AS8026B
  • Current
Published 2019-08-14 by SAE International in United States
This standard covers oxygen masks and breathing valves used with both panel mounted and mask mounted demand and pressure-demand oxygen regulators. Mask mounted oxygen regulators are covered under other standards, but when the mask mounted regulator incorporates an integral exhalation valve, the performance of this valve shall meet the requirements of this standard.

Development of Subject-Specific Elderly Female Finite Element Models for Vehicle Safety

Chongqing University-Yunlei Yin, Junming Li, Qingmiao Wang
State Key Lab of Veh NVH & Safety Technology/Chongqing Univ-Wenxiang Dong, Zhenfei Zhan
Published 2019-04-02 by SAE International in United States
Previous study suggested that female, thin, obese, and older occupants had a higher risk of death and serious injury in motor vehicle crashes. Human body finite element models were a valuable tool in the study of injury biomechanics. The mesh deformation method based on radial basis function(RBF) was an attractive alternative for morphing baseline model to target models. Generally, when a complex model contained many elements and nodes, it was impossible to use all surface nodes as landmarks in RBF interpolation process, due to its prohibitive computational cost. To improve the efficiency, the current technique was to averagely select a set of nodes as landmarks from all surface nodes. In fact, the location and the number of selected landmarks had an important effect on the accuracy of mesh deformation. Hence, how to select important nodes as landmarks was a significant issue. In the paper, an efficient peak point-selection RBF mesh deformation method was used to select landmarks. The multiple peak points were selected to expand landmarks set, so as to improve the morphing quality compared…

Influence of DISH, Ankylosis, Spondylosis and Osteophytes on Serious-to-Fatal Spinal Fractures and Cord Injury in Rear Impacts

Collision Research & Analysis Inc.-Samuel White
ProBiomechanics LLC-David Viano, Chantal Parenteau
Published 2019-04-02 by SAE International in United States
Seats have become stronger over the past two decades and remain more upright in rear impacts. While head restraints are higher and more forward providing support for the head and neck, serious-to-fatal injuries to the thoracic and cervical spine have been seen in occupants with spinal disorders, such as DISH (diffuse idiopathic skeletal hyperostosis), ankylosis, spondylosis and/or osteophytes that ossify the joints in the spine. This case study addresses the influence of spinal disorders on fracture-dislocation and spinal cord injury in rear impacts with relatively upright seats. Nineteen field accidents were investigated where serious-to-fatal injuries of the thoracic and cervical spine occurred with the seat remaining upright or slightly reclined. The occupants were lap-shoulder belted, some with belt pretensioning and cinching latch plate. The occupants were older and had pre-existing disorders of the spine, including DISH, ankylosis, spondylosis and/or osteophytes that ossify the spinal joints. The crashes were summarized and the mechanism for injury was analyzed. The 19 cases involved fracture-dislocation and spinal cord injury at areas of the spine where DISH, ankylosis, spondylosis and/or…

Comfortable Head and Neck Postures in Reclined Seating for Use in Automobile Head Rest Design

University of Michigan-Matthew Reed, Sheila Ebert, Monica Jones
Published 2019-04-02 by SAE International in United States
Little information is available on passenger preferences for posture and support in highly reclined seat configurations. To address this gap, a laboratory study was conducted with 24 adult passengers at seat back angles from 23 to 53 degrees. Passenger preferences for head and neck posture with and without head support were recorded. This paper presents the characteristics of the passengers’ preferred head support with respect to thorax, head, and neck posture.
