Chances are, many petite ladies who drive Iriz Premium going to miss the side airbags. Unless as a driver, she adjusted the seat to be in high position. Unfortunately, the front passenger seat is non-adjustable, so as the rear ones.
Kia Rio which is a budget B-segment car also doesn't have many cushion parts (the parts that are inflated) on its side airbags. But the good thing is, those critical cushion parts are located at the right place. Especially, for the rear passengers.
CLEARLY, the side airbag's design in Iriz has a flaw that needs rectification.
1. Good observation. The current side impact test is using EUROSID (EURO Side Impact Dummy), which used European anthropometric data which is not really represent the whole world population. It will be replaced by WorldSID.Kia Rio which is a budget B-segment car also doesn't have many cushion parts (the parts that are inflated) on its side airbags. But the good thing is, those critical cushion parts are located at the right place. Especially, for the rear passengers.

2. However, it does not means the iriz airbag need rectification. The shorter you are, the higher the distance between your head and the B-pillar --> you'll be less likely hit by the B-pillar. View the car from front and you'll understand what I mean. For shorter people, the B-pillar will hit the rib first, pushing the head away from B-pillar. (B-Pillar is always designed to be weaker at the base).
As you can see, the top portion of B-pillar is HPF (1500MPa) while the bottom one is Tailor Welded Blank 500MPa steel. This allows pendulum like movement, reducing the B-pillar intrusion around your head. Check the graph, intrusion level (green colored line), if you're taller, you're more susceptible getting hit on the head.
3. The side airbag coverage for the rear passenger is almost 100% of rear door glass due to assumptions the child is placed on the back seat.
4. The airbag is shorter on the longitudinal direction is due to there is no requirement for small overlap test (extra portion of the airbag @ A-pillar is required to cushion the acceleration of head during small overlap test). Refer statement below.

The Camry’s driver airbag and side curtain airbag deployed, but the steering wheel moved so far to the right that the dummy’s head made only minimal contact with the front airbag. The side curtain airbag didn’t extend far enough forward to help prevent the dummy’s head from hitting the instrument panel.
