Where are the A-pillar and B-pillar located on a car body?

[OCora]

The positions of the A-pillar and B-pillar on a car body: the A-pillar is located on both sides of the front windshield, and the B-pillar is located behind the main and co-driver doors. There are three pillars on both sides of the glass between the front windshield and the front and rear doors, which are the front pillar (A-pillar), middle pillar (B-pillar), and rear pillar (C-pillar) from front to back. The A-pillar, B-pillar, and C-pillar of a car are all part of the body frame, which can protect the occupants in the event of a collision. The car body consists of body panels and the body frame. The body panels include the front and rear bumpers, front fenders, engine hood, doors, and trunk lid. The roof and rear fenders are welded to the body frame, so the roof and rear fenders also belong to the body frame.
