Future of Toyota Side Air Bag System

• By the 2001 MY, all Toyota and Lexus vehicles had side torso air bags as either standard or optional equipment.

• Toyota plans to offer curtain shield air bags on all models by 2005.

Toyota Assessment of SAB Systems• From the beginning of Toyota’s SAB

development, systems were assessed by stringent internal standards.

• These internal standards included assessment of OOP risk to children.

• Since the OOP voluntary procedures were published (August 2000), all Toyota systems are designed according to these procedures.

OOP Test Results – Chest• Most challenging loading to the chest occurred

for the 3 yo Rear Facing Position.

13

OOP Test Results of Large Sedan

• Large Sedan

• Assessment using Voluntary OOP Test Procedures

• Seat mounted torso bag

• Curtain Shield air bag (front and rear)

14
