Name two types of side airbags that protect the head.

Inflatable curtains are specifically designed to deploy along the sides of the vehicle in the event of a collision, providing a cushioning effect and protection primarily for the head in side-impact crashes. This design works effectively to reduce the chances of head injuries by creating a barrier between the occupant and the side windows or intruding objects.

The mention of tubular airbags is often associated with those that can deploy along the side pillars of the vehicle, offering additional head protection. These types of airbags are intended to absorb energy and minimize impact forces.

In contrast, the other options do not specifically define the types of airbags that are intended for head protection in side impacts. "Trabecular" does not refer to a recognized type of side airbag. Driver and passenger airbags typically refer to frontal airbags designed for front-impact scenarios rather than side protection. Therefore, the choice indicating tubular and inflatable curtains accurately describes the types of side airbags aimed at safeguarding the head.
