Abstract: An apparatus includes a roll former with rolls configured to form a structural beam from sheet material, and a sweep unit for longitudinally sweeping a beam in any of vertical, horizontal, or combination directions. The sweep unit has a first pair of forming rolls positioned to engage first opposing sides of the structural beam and has a second pair of forming rolls positioned to engage second opposing sides of the structural beam. The sweep unit movably supports the first and second pairs of forming rolls so that any selected one of the forming rolls continuously engages an associated side of the structural beam while an associated one of the forming rolls opposing the selected one forming roll moves downstream and around the selected one forming roll. This provides a very stable beam-bending condition promoting dimensional stability during the sweeping process, and hence dimensional accuracy and repeatability.

Abstract: A door beam assembly for a passenger vehicle comprises a roll formed longitudinally-swept tubular beam having a constant cross section defining a generally-orthogonal shape, with the outside wall having an integral channel rib formed into the wall to stiffen the wall. C-shaped mounting brackets are attached to beam ends, with opposing walls welded to and supporting walls of the beam, and with a transverse wall spaced from the adjacent wall of the beam. In one aspect, right and left door beam assemblies includes identical beams, front and rear mounting brackets attached to each end, and identical center brackets.

Abstract: A roll former for forming a sheet into a continuous multi-tubular reinforcement beam. The roll former includes a first set of rollers that are configured to bend the sheet to form a common center wall in generally perpendicular orientation relative to first and second lateral portions of the sheet that extend in opposing directions from respective first and second radiused ends of the common center wall. The first set of rollers also form radiused edges on the first and second lateral portions. A second set of rollers is configured to form a channel rib longitudinally along each of the first and second lateral portions. A third set of rollers is configured to bend the first and second lateral portions simultaneously and equally to abut the first and second radiused edges with the respective first and second radiused ends of the common center wall to define adjacent tubes of the beam.

Abstract: An integrated assembly includes a bumper energy absorber section with crush lobes for abutting a bumper beam, an upper air shutter section with subassembled shutter members movable between closed and open positions, a first actuator mechanism for moving the shutter members between positions, an upper fascia support section with upper leg crush lobe therein above the upper air shutter section, a lower air shutter section with subassembled lower shutter members movable between closed and open positions, a second actuator mechanism for moving the lower shutter members between the positions; and a lower leg energy absorber section attached below the lower air shutter section and configured to abut (or replace) a face of a secondary pedestrian impact bar. The shutter members may be molded to a shutter frame using over molding technology rather than separately, manually assembled.

Abstract: An energy absorber includes opposing aligned crush lobes expandable in opposite directions, and when expanded, potentially collapse with different energy-absorbing rates and stroke distances. The energy absorber forms a subassembly design that is adaptable and easily modified for predetermined energy absorption crush curves and specific energy-absorbing circumstances, such that it can be used inside a vehicle passenger compartment or outside a vehicle in different locations, such as for a knee bolster on the instrument panel, or on a door inner panel, or on an under-knee seat component, or on a headliner or A-pillar cover, or hood-lifter for pedestrian safety. One version of the energy absorber includes formed sheets bonded along a perimeter to define two cavities and an inflator-holding pocket connected to the cavities by integrally-formed tunnels.

Abstract: An internal deployable vehicle panel assembly includes an inner panel, an outer panel and a deployable energy absorber. The inner panel includes a first mounting structure that movably couples the inner panel to a vehicle component to move between a closed position to cover an access opening to a vehicle storage compartment and an open position to reveal the access opening. The outer panel includes a second mounting structure that is removably coupled to a third mounting structure of the inner panel. The deployable energy absorber is disposed between the inner and outer panels in an undeployed state. The deployable energy absorber is free from fixed attachment to the outer panel and energizable to a deployed state in which the deployable energy absorber separates the outer panel from the inner panel and displaces the outer panel away from the inner panel.

Abstract: A vehicle cowl component configured to extend between a hood's rear edge and a vehicle front windshield comprises a cowl and a seal, the seal including a U-shaped cross section attached to the under-hood edge and having upwardly extending front and rear curved walls, each of the curved walls having an unconnected free end. In one embodiment, the seal is two-shot molded onto the cowl, which eliminates secondary attachment operations. A method includes steps of first-shot molding a cowl, and then second-shot molding a U-shaped seal onto the cowl along an under-hood front edge. A modified cowl includes a seal with a downwardly extending wiper for sealing engagement with a body support structure under the cowl and seal.

Abstract: A vehicle cowl cover includes a windshield support portion and a channel portion. The windshield support portion includes a first windshield supporting wall and a second windshield supporting wall coupled to the first windshield supporting wall to define a windshield receiving cavity that is configured to receive a bottom edge of a windshield. The windshield receiving cavity extends in a lateral direction along the bottom edge of the windshield. The channel portion extends from the second windshield supporting wall and defines a water receiving channel that is configured to receive water that flows over a top edge of the second windshield supporting wall from the windshield receiving cavity. The channel portion is angled relative to an inner surface of the windshield to direct water laterally along the channel portion to at least one side edge of the vehicle cowl cover.

Abstract: An integrated assembly includes a vehicle bumper system, and upper and lower air shutter sections with subassembled shutter vanes movable between closed and open positions, an actuator mechanism for moving the shutter members between positions. When in the fully open position, the shutter vanes are aerodynamically designed to minimize air drag, both as air flows past the vanes and also during after-vane airflow (and during after-bumper-beam airflow). When in the fully closed vane position, the vanes seal against each other to provide a highly efficient and leak-resistant air-blocking assembly.

Abstract: An apparatus forms a sheet into a beam having four exterior walls and a common center leg extending between an opposing two of the walls. The apparatus includes a roll former forming the sheet into the beam cross section, a welding station with top and bottom laser welders, and a weld box fixture having inwardly-biased external mandrels (biased by actuators) and outwardly-biased internal split mandrels (biased by springs) that interact to hold a desired shape of the beam in the weld fixture, and also includes a sweeping unit and cutoff device. By this arrangement, the internal and external mandrels, in combination with a bias of the actuators and springs, control a shape of the beam by flexure and movement of material of the sheet when in the weld box fixture during a welding process of the welder.

Abstract: A co-molding process includes molding a body between a “common cavity” and “first shot core” die halves, co-molding a soft plastic onto the first component to form a final part using the “common cavity” die half and a “second shot core” die half. The “second shot core” die half includes shallow formations forming expansion locks along an elongated edge of the final part on a non-show concave surface, the locks having a shallow depth and extending in a direction non-parallel a die pull direction such that the locks affirmatively prevent shifting of first component during the co-molding process. Also, the locks can be made to cause the final part to remain with the “second shot core” die half when dies are opened during a final step of the co-molding process.

Abstract: An energy absorbing system includes a hood with inner and outer panels defining a rear edge cavity, and a pair of polymeric energy absorbers in the cavity. The hood and energy absorber are tuned to minimize an HIC value when a pedestrian's head contacts the hood during an impact to absorb energy prior to the hood bottoming out on the plenum of the vehicle. The energy absorber is preferably made of a polymeric material capable of withstanding high temperatures associated with going through a paint over or e-coat process, such as high temperature nylon. The illustrated energy absorber has a hat-shaped cross section and includes criss-crossing flanges tuned to provide an optimal force-deflection curve during impact.
