B-Pillar
The B-pillar is the central roof support between the front and rear doors, holding the front seatbelt anchor.
What is B-Pillar?
It is reinforced to protect occupants in side impacts. Some coupés and hardtops have no visible B-pillar. Seat belt height adjusters are often mounted on it. In crash tests, how much the B-pillar is pushed inwards is a key measure of side-impact protection.
How it works
Hot-formed ultra-high-strength steel resists intrusion into the cabin during a side crash.
Why it matters for your car
B-pillar repairs need manufacturer methods because of the special steels. Some pillars contain sensors for side airbags.
