A-, B-, and C-Pillars: Pillars are members that are more or less vertical below the belt line, hollow and constructed of stamped sheet metal panels spot welded together, that bracket the door openings. They are labeled A, B, C, etc., from front to back. Thus, the A-pillar is the front door hinge pillar, and the B-pillar is the front door latch pillar (and the rear door hinge pillar as well, if there is a rear door). Some vehicles (such as vans and sport utility vehicles (SUVs)) have D-pillars as well.
Development and assessment of alternative designs for side impact beam

The number of people who are death in car accidents on the roadways of the world is still at an unacceptable level. Accidents on the world’s roads claim the lives of over 3,700 people daily. According to the World Health ranking report published in 2018, almost fifty percent of deaths worldwide result from deadly automobile accidents [1]. When accident statistics are examined, it is seen that side collisions constitute 30% of all accidents and 35% of them are fatal [2]. In addition, side collisions are riskier than frontal collisions as there are no unique bumpers to absorb the impacts and the space between the passenger and the door is very limited. Therefore, side collisions are significant in vehicle safety when considering accident rates and risks. In such accidents, passenger safety is ensured by the A, B, and C-Pillar and the side impact beam. The B pillar between the doors helps to keep the vehicle’s roof and floor in place. There are two sections to the B-Pillar, an exterior layer and an inner layer. Typically, steel or aluminum is used to create these two layers and welded together. The B-Pillar construction is designed to absorb most impact energy with minimal distortion. A side impact beam is a passive safety device installed within a ground vehicle’s door frame. Its purpose is to protect the occupants of the vehicle from suffering injuries in the case of a side accident [3].
Feasibility of one-shot forming for manufacturing of steel/CFRP hybrid B-pillar

In this study, steel reinforcements of the B-pillar were substituted with a CFRP reinforcement to reduce the weight of automotive parts and remove the additional assembly process. The B-pillar outer panel and CFRP reinforcement were assembled using epoxy resin impregnated within the CFRP prepreg without any additional adhesive and fastener. Figure 4 shows the components of the conventional and hybrid B-pillars. The conventional B-pillar is composed of outer panel and steel reinforcements, such as upper and lower reinforcements and bracket. These components are substituted with CFRP reinforcement in the hybrid B-pillar. The outer panel of the hybrid B-pillar was manufactured with a tailor-welded blank (TWB) for further weight reduction.
Analyzing the invisibility angles formed by vehicle blind spots to increase driver’s field of view and traffic safety

The vehicle B pillar, or center pillar, is made of steel or aluminum. It starts at the end of the front door where it is welded to the ceiling panel at the top and to the vehicle’s floor pan at the bottom. The B pillar is considered a complex structure of the vehicle body because the front door closes on it. In addition, B pillars are responsible for attaching the door latch to the body [19]. Some vehicles are designed without a B pillar, which increases the field of view.
