A-pillar joint for automotive vehicles

摘要

An A-pillar joint configuration where the front end frame rail members are welded to the A-pillar eliminates the seals at the interface between the front end frame rail members and the A-pillars. The front flange of the A-pillar is also eliminated in the hydroformed configuration while the hydroformed frame rail members are formed with rearward ends that mate with the shape of A-pillar to positioned flattened ends against the exterior vertical side of the A-pillars for welding thereto. The resulting joint configuration eliminates the openings in the A-pillar for the passage of the front end frame rail members requiring seals to insulate the passenger compartment from engine and road noises.
