● comfort
drivers will have a feeling that the angle of the driver’s line of sight always been more or less obscured. Wide experience actually noted 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 must 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.
● Security
with a nice view of the vehicle is not enough to explain stiffness. The key fact is that a nice view windshield. They are used in car windshield glass surface, from the aerodynamic point of view, the curved glass oncoming flow of air through the vortex to reduce turbulence and to reduce 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, some car windshield has a large area of vision is from the windshield area. Meanwhile windscreen having a sandwich structure, a material composed of three different thicknesses, improves the mechanical strength and insulation properties. Concept

between the top of the cockpit and the engine compartment, the left and right A-pillars mirror, you will block a portion of the horizon turn, left turn in particular, some more so than discussion.
B pillar between the front and rear seats cockpit, is Flanagan thick stick between the longitudinal sides of the two doors, extend from the roof to the bottom of the vehicle, viewed from inside, in the seat belt B column. Both
C pillar of the headrest in the back seat.
In summary, A pillar, B pillar and the C pillar are a main part of the structural strength of the vehicle support.
