What does a Type 2 seat belt assembly consist of?

A Type 2 seat belt assembly is designed to enhance passenger safety by specifically incorporating a combination of pelvic and upper torso restraints. This configuration is crucial because it offers a more comprehensive restraint system during a collision, as it helps keep both the lower body and upper body secured in the seat. By preventing excessive movement of both parts of the body, the risk of injury can be significantly reduced.

In contrast, a lap belt only would provide insufficient protection, as it only restrains the lower part of the body. A torso restraint alone would not secure the pelvis, making it less effective for overall safety. A standard safety belt without additional features might lack the designed ergonomics and safety enhancements present in a Type 2 assembly. Therefore, option B accurately describes the essential components of a Type 2 seat belt assembly, emphasizing the importance of both pelvic and upper torso restraints in optimizing passenger safety.
