What is the A-pillar?
in the car magazines, car buyers guide often see this argument “B pillar” “C pillars” “A pillar.” Wherein the A-pillar refers to: a column between the left front door and the windshield.
In fact, the car’s A-pillar, B pillar, C-pillar has its own different functions, but also that their contradictions, such as the conflict between the vision and the stiffness of the A-pillar, the stiffness and convenience of contradictions B-pillar Wait.
A column edit this paragraph Why would affect vision?
possible drivers will have a feeling, if the angle of the driver’s line of sight is not blocked nice, spacious feel in fact be noted that a comfort issue, but it seems that this is a car designer contradiction. In general, the driver’s line of sight through the A-pillar, 5 — binocular overlap angle 6 degrees, if the start angle according to the driver’s comfort, the overlap angle the smaller the better, the thinner the better the A-pillar, but need to have a balance in the designer’s eyes, it is clear that he had to ensure high rigidity of the a-pillars to reduce security risks, so from this point of view, the a-pillar is not as small as possible.

where a multi-plug. Some may ask that those who like a nice view of the vehicle is not able to say stiffness enough? Such as the Peugeot 307. The answer is no, 307 trick is a nice view to the front windshield. We know that cars are used in curved glass windshield, first of all from the perspective of aerodynamics. Oncoming airflow through the curved glass to reduce eddy currents and turbulence, thereby reducing air resistance. Further, curved glass having a high strength, thinner glass may be used, a certain weight loss of significance for cars. With curved glass, windshield Peugeot 307 with an area of 1.46m2, the vision is from the area on the windshield. Meanwhile windscreen having a sandwich structure, a material composed of three different thicknesses, improves the mechanical strength and insulation properties.
