What is a Type 1 seat belt assembly?

A Type 1 seat belt assembly refers specifically to a lap belt designed primarily for pelvic restraint. This means it functions to secure the occupant's hips and lower body, reducing the likelihood of injury in the event of a collision by preventing excessive movement.

This type of seat belt is fundamental in vehicle safety design, as its primary purpose is to hold the occupant in place during sudden stops or impacts, effectively minimizing the risk of lower body injuries. While seat belts may have varying designs—some providing upper-torso support or more complex motorized mechanisms—Type 1 specifically denotes this simpler, yet crucial, function.

Understanding this type of seat belt is essential in the context of vehicle safety, as it underscores the need for proper restraint systems designed to protect occupants effectively during accidents.
