Abstract: An aluminum alloy vehicle structural component defining an out-of-plane aperture with its main portion. A recessed portion is inset from the main portion having a bed sub-portion out-of-plane with the main portion that defines the aperture. The recessed portion also provides a strain hardened sub-portion, or stiffened ring of material, around the aperture. When the main portion is subjected to in-plane tension due to bending, the strain primarily concentrates along the strain hardened sub-portion (the stiffened ring) and by-passes the aperture. As a result the perimeter of the aperture undergoes less straining than if the aperture was in-plane with the main portion. The out-of-plane aperture, the bed sub-portion surrounding the aperture, and the strain hardened sub-portion surrounding the bed sub-portion may improve the overall structural robustness of the aluminum alloy structural component when subjected to in-plane tension.

Abstract: A pedestrian safety system for use with a motor vehicle includes a vehicle hood movable between a closed position and a raised position wherein a leading edge of the hood is raised relative to a front surface of the vehicle to form a gap, and a leg stiffener movable between a retracted position wherein it is beneath the hood when the hood is closed and a deployed position wherein the stiffener projects through the gap and is forward of the leading edge of the hood when the hood is raised. At least one actuator mounted beneath the hood moves the stiffener between the retracted and deployed positions. A remote sensing system detects an impending collision with a pedestrian and triggers the raising of the hood and extension of the actuators.

Abstract: A vehicle bumper energy absorber system includes a foam energy absorber (EA) for transverse mounting forward of a bumper and having a plurality of cavities formed therein. Variable-stiffness elements are located within the cavities and embedded within the EA. The variable-stiffness elements are formed from open-cell foam treated with magneto-rheological fluid. Electromagnetic devices are co-located with the respective elements and are energized to create magnetic fields acting on the magneto-rheological the elements and thereby increase the stiffness of the elements. When energized, the elements increase the overall stiffness of the EA/element system. When the electromagnetic devices are not energized, the stiffness of the EA by itself is relatively low to meet pedestrian protection goals. At speeds where pedestrian protection is not required but low-speed damageability goals are important, the electromagnetic devices are energized to stiffen the EA/element system.

Abstract: A seat belt system includes a spool, a harness, a wedge clamp, and a load limiting plate. The harness is at least partially wound about the spool. The wedge clamp selectively engages the harness. The load limiting plate, which has deformable teeth, is operably attached to the spool. The teeth engage a pin. The pin deforms the teeth after a vehicle impact.

Abstract: A vehicle includes a dash panel and an airbag module disposed behind the dash panel. The airbag module includes an airbag assembly that defines, upon inflation in a presence of a passenger, a primary chamber adjacent to a passenger side of the vehicle and configured to cushion the passenger upon impact, and a secondary chamber attached to the primary chamber, arranged adjacent to a center of the vehicle, and configured to catch the passenger after impact. The secondary chamber has an end portion disposed adjacent to the passenger and a base opposite and wider than the end portion arranged to sit against the dash panel to orient the airbag assembly relative to the passenger.

Abstract: A vehicle includes an armrest and a hinge assembly. The hinge assembly supports the armrest and is rotatable between extended and collapsed positions. The hinge assembly includes a pin configured to move between locked and released positions. When the pin is in the locked position, the hinge assembly is locked in the extended position. When the pin is in the released position, the pin is configured to permit rotation of the hinge assembly toward the collapsed position.

Abstract: A roof bow for a vehicle is provided that has a “bow-tie” shape including a central portion flanked by two triangular portions. The triangular portions are joined to right and left roof brackets that are, in turn, joined to right and left roof rails. The bow-tie roof bow may be assembled from extruded tubular parts. The bow-tie roof bow may be assembled in a clamshell structure including an upper shell and a lower shell that are joined together by welding. The roof bow may be formed in one piece as a sheet metal stamping having side portions that are wider than the central portion.

Abstract: A head rest is mountable on a vehicle seat back with at least one hollow support bar. The support bar is adjustable to adjust the height of the head rest relative to the seat back. An airbag is located in the head rest and a connection is provided in the hollow head rest support bar between the airbag and an airbag system component in the seatback.
