Airbag Systems |
|
|
| Abstract |
|
|
| This report looks at
the evolution of airbag technology , moving from a relatively simple,
stand alone supplemental inflatable restraint device, to a much more
sophisticated and integrated occupant restraint system. Many factors
influence this evolution, including technology development, regulation,
field experience, and public opinion. In this report, market dynamics.
A clear definition of an intelligent occupant restraint system is
provided. Industry trends are examined, including the structure of
the market, trends in occupant sensing, inflator and pretensioner
evolution, and changes to crash sensing. The report discusses system
cost, as well regulatory and insurance issues affecting intelligent
airbag systems. NHTSA proposals and programs relating to intelligent
airbags are described. |

Inflator Technology |
|
|
| Abstract |
|
|
| This study focuses
on inflator technologies commonly employed in modern automobile
airbags. Inflator provide the working gas needed to deploy the airbag
system, and are typically the single most complex and expensive
component in an airbag module. The study reports on driver, passenger,
side impact, and smart inflator systems, as well as supplementary
systems designed to protect specific body regions. Included in the
study are sections covering pyrotechnic, compressed gas, and hybrid
technologies. The pyrotechnic section scrutinize the older sodium
abide designs and the newer, non-azide based gas generants. Compressed
gas covers heat-augmented technologies such as combustible liquids
and gaseous fuels. Hybrid inflators, the implementation of compressed
gas and pyrotechnic technologies in one package are reviewed as
an approach usually employed on passenger side applications. Also
examined are, multi-staged inflators exhibiting differing inflation
rates depending on crash severity, occupant weight and position.
Diagrams of all design concepts are included with component-level
detail. Issues such as inflator aggressivity, toxicity, cost, recycling,
and weight are addressed |

Report: Initiators |
|
|
| Abstract |
|
|
| The initiator is a
pytrotechnic device that combusts when given a specific electrical
signal to ignite/activate airbag inflators and pyrotechnic pretensioners.
This study reports on the various types of initiators and the technology
behind this important pyrotechnic component. Cost an construction
are examined, as are firing specifications and overall reliability.
Both semiconductor and the more common bridgewire designs are covered.
The report highlights the advantages and disadvantages of the various
design types with detailed assessment of the different pytrotechnic
charges employed. Further analysis is made regarding the methodologies
used to provide protection from transient electrical charges with
the advantages and disadvantages of each method outlined. Various
initiator suppliers are reviewed, and forecasts are made regarding
initiator volume and supplier market share. |

| Multiplexed
Systems Market and Technology |
|
|
| Abstract |
|
|
| Multiplexed occupant
restraint systems will begin to displace conventional systems beginning
in 2000-2001. This study reports all aspects of this displacement.
Effects on cost, design, reliability, and even inventories are examined.
This study highlights, the market for multiplexed restraint systems,
its forecasts, cost analysis, industry structure, and various systems
and electronics suppliers. It also includes, assessments of multiplexing
architectures including the effect on communications bus, individual
nodes, address length, and power supply requirements. Further analysis
includes connectors required by the system, the market, suppliers
and their designs. Electronic Control Unit (ECU) technologies are
described, including safeing sensors, side impact sensors, accelerometers
and occupant sensors. As well, a new market emerges for high technology
capacitors. Bridgewire and semiconductor initiator components will
also change to meet new reliability and protection circuit schemes.
Each of the technologies, their suppliers and markets are reported
upon. |

Report: Seatbelt Pretensioners |
|
|
| Abstract |
|
|
|
Pretensioners are devices
that tighten the seatbelt a prescribed amount upon sensing a crash
event. This report focuses on the most commonly used type, the
pyrotechnic pretensioner, though other technologies are briefly
covered. The study includes history and operational characteristics
of pretensioners, the pyrotechnics employed and the various means
of ignition. Significant detail is given to the technical issues
of effluent toxicity, long term aging, overall complexity, effectiveness
and cost. The pretensioner market is described in detail with
further analysis of acceptance and forecast of installation rates
in various countries. Volumes, price, and market shares are provided.
The report profiles those automakers employing seatbelt pretensioners
and their suppliers. The report also covers legislation and insurance
issues that effect usage and acceptance in Europe, North America
and Japan.

Report: Occupant Sensors |
| |
| Abstract |
| |
| This report focuses
on various devices and technologies intended to sense the presence
of an occupant in an automobile seat. It covers sensors of all types
from the seat is occupied to more complicated systems that determine
occupant weight and position to manage the airbag deployment. The
importance of these sensors are examined relative to the history
of airbags and the development of the new "Smart: airbag systems.
System information requirements are analyzed, as are various crash
scenarios and frontal occupant situation and characteristics. More
than 10 different sensor types are addressed, with detail on the
underlying technology (advantages and disadvantages) behind each
type, i.e.; ultrasonic, infrared, electric field and film resistive,
to name a few. Market considerations are also given significant
attention, with specific topics including forecasts of installation
rates, volumes, pricing and major market players. The report reviews
real and potential alliances formed to tackle the problem of supplying
inexpensive but reliable occupant sensing on a mass-produced scale.
Regulatory issues affecting intelligent airbag systems and occupant
sensors are also analyzed. |
