<p>A vehicle side door or hatchback structure incorporates at least one hydroformed component. In one configuration, a window frame (54), a door frame (50) and a reinforcement member (52) are press-fit together by pressurized fluid during a hydroforming process to join the frames and the reinforcement member together. In another configuration, a vehicle hatchback frame subassembly includes a one-piece hydroformed window frame (104) with a central portion (138) disposed between opposing end portions (134, 136). Inner (106) and outer (100) panels are attached to each other and secured to the opposing end portions (134, 136) of the window frame (104). In yet another configuration, a vehicle door and window frame subassembly includes a hydroformed one-piece first door frame (252), a roll formed second door frame (256), and a reinforcement member (258) secured to the tubular one-piece first door frame. An outer front panel (250) is attached to the reinforcement member (258) by at least one mirror bracket (398). In a modification of this configuration, a mirror bracket (450) which additionally defines a door hinge element (451) interconnects an end of the reinforcement member (258') to an end (455) of the tubular one-piece first door frame (252'). In a further configuration, a 'frameless' vehicle door subassembly includes a lower tubular member (504) and an upper tubular member (510) secured together at their ends by a pair of hydroformed members (506, 508).</p> |
