What are the pillars of a car? ›

The pillars on a car with permanent roof body style (such as four-door sedans) are the vertical or nearly vertical supports of its window area or greenhouse—designated respectively as the A, B, C and (in larger cars such as 4-door station wagons and sport utility vehicles) D-pillar, moving from front to rear, in ...

In the case of cars, “pillars” refer to roof pillars, and they're lettered front to back. A-Pillars straddle the windshield, B-Pillars are in the middle of the passenger compartment (just behind the front doors) and C-Pillars are those at the rear of the passenger compartment.

The vertical support that provides structural integrity to a vehicle's roof is called a roof pillar. Most cars have three different pillars, but station wagons, minivans, and SUVs usually have at least four. Each pillar is assigned a letter from A to D to indicate where it is on the vehicle.

The vertical roof support structure located between the front and rear doors on a typical vehicle. It corresponds with the A pillar located on either side of the windshield at the front of the car and the C pillar which sits on either side of the rear window on a typical sedan.

The pillars represent the order that the states, moving from left to right in the illustrations, ratified the Constitution. (The entire series is available from the Library of Congress.)

As a large solid structure, pillars provide firm support for another larger structure. Pillars distribute the weight from a roof or ceiling and support heavy loads. In construction, they often serve to make buildings more attractive and are used to exhibit freestanding monuments.

The A-pillar supports the windshield. The B pillar is between the front and back door windows/frames. The C-pillar is where the back window slopes down to meet the body again or wraps around the back of the vehicle on a station wagon/estate or SUV.

pillar refers to any isolated, vertical structural member such as a pier, column, or post. A beam is a structural element that is capable of bearing load principally by resisting against bending.

A pillar is a large, typically cylindrical or square, solid structure that stands upright as support in a home or building, either structurally or aesthetically.

Severely damage pillars can be cut out and new pieces, perhaps from a donor car, welded in with proper reinforcing or overlap to preserve structural strength - once had this done with a B-pillar.

A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. It now also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding or crashing into pedestrians and structures.

The roof support structure on either side of the rear window on a typical sedan or coupe. It corresponds with the A pillar located on either side of the windshield at the front of the car and the B pillar which sits between the front and rear doors on a typical sedan.

The B pillars are the ones between the front and rear doors on a 4 door model or the vertical section between the front and rear windows of a two door. On what is refereed to as a hardtop or coupe the B pillar is often left out.

Typically, the elastomeric seals for both the windshield and the adjacent portion of the front doors are mounted on the flanges of the A-pillars. The door opening panel is typically welded on the outside of the A-pillar structure to provide a uniform surface against which the front door can close.

The A pillar on a car is the metal piece that runs up the left and right side of the front windshield.
