Passenger restraint systems

Seatbelt assemblies or seatbelt modules include the straps, webbing, buckles, adjusting mechanisms, fasteners, and related hardware designed to secure people in a vehicle to minimize risk of harm in a collision. Most modules are mechanical, but some contain a pyrotechnic or compressed gas seatbelt pretensioner which, in an emergency, forces the retractor to take up any slack in the seatbelt.

As an example, we describe the work flow for developing an angular-rate sensor, which is implemented in automobile navigation systems as a supplementary inertial-detection system in addition to GPS. (Sensors of similar design are also used in passenger-restraint systems for rollover detection.)... 

The transformation of the car interior over the last 20 years has been closely involved with safety legislation. The introduction of resilient plastic skin materials with foam backing, together with sophisticated nylon and acetal-based seat passenger restraint systems, has delivered all that has been asked for, at the present level of passenger packaging requirements. 

The relationship between injury criteria and the mechanics of restraint systems are important to insure the safety of wheelchair users in motor vehicles. Hip and head deflection are often used criteria for determining potential injury. The automotive industry has invested considerable effort for research and development to protect vehicle passengers. Research is not nearly extensive for the passenger who remains seated in a wheelchair while traveling. Many wheelchair and occupant restraint systems copy the designs used for standard automobile seats. However, this type of design may not be appropriate. 

A type of vehicle restraint system that consists of inflatable bags monnted in the interior of a vehicle that automatically inflate npon a collision to protect the occn-pants from injury. They are designed for frontal impact crashes. This type of crash accounts for more than half of all passenger vehicle occupant deaths. Air bags are designed to limit head and chest injnries. They are considered only supplemental to safety belts they do not replace them. 

Restraint systems n. An end use for textile fibers restraint systems are devices such as air bags, seat belts, and shoulder harnesses for passenger protection in automobile, trucks, airplanes, etc. 

The methods discussed earlier are applied to the seat-occupant-restraint system of an aircraft. To improve passenger safety, the design and the arrangement of the seats. 

Real world coUisions are not always covered by standards. For example, crash tests on road restraint systems (crash barriers) can go only some of the way in predicting how vehicles (and their passengers) will perform in the wide variety of impact speeds and angles that can happen in real crashes.
