Abstract: A vehicle tailgate lift assist system comprises a vehicle tailgate adapted to open and close by rotating about a tailgate pivot axis in relation to a vehicle body, coupling means to releasably connect the vehicle tailgate and the vehicle body, an energy storage device located within the vehicle body and adapted to be pivotally anchored to the vehicle body at one end, a crank arm pivotally attached to the energy storage device at a second end of the energy storage device and rigidly attached to an actuation shaft that is coaxially aligned with the tailgate pivot axis, and a pivot bracket assembly comprising a mounting bracket fixed to the vehicle body and holding a pivot bearing arrangement to facilitate a robust rotary joint about the tailgate pivot axis. The pivot bearing arrangement comprises a unitary component overmolded to a pivot sleeve to act as a bushing between the actuation shaft and the pivot sleeve, such that relative rotary motion of the tailgate and the vehicle body results in linear movement of the energy storage device and maximum energy storage at the tailgate fully open position.

Abstract: A pedestrian protection automotive hood hinge comprises a release assembly which comprises a retainer supported by one of a first member and a second member and a releasable pin supported by the other of the one of the first and second members. The releasable pin is captured in the retainer in the normally closed position and the normally opened position. An actuator is configured to engage the second member and move the second member upward relative to the first member in response to a collision input. The releasable pin is configured to be released by the retainer in response to the collision input permitting the second member to pivot about a member pin relative to the first member to an opened hood collision position. A retention link with a retention pin moves in a controlled manner during a collision so that the retention pin engages a retention slot. At maximum opening of the hood, the retention pin engages a retention clip adjacent the retention slot and begins to rebound. With continued force exerted by the hood on the retention clip, the retention pin passes through and exits the retention clip and the hood decelerates to a final post collision position.

Abstract: An automotive door hinge comprises first and second brackets mountable selectively to one of the door and the body. A cam element, non-rotationally mounted to the second bracket, comprises a cam surface adapted to engage with a cam follower non-rotationally housed within a first housing of the first bracket. An energy storage means respectively stores and releases energy when the cam follower longitudinally translates within the first housing in a first direction and then in a second direction opposite the first direction. Relative rotation of the first bracket in relation to the second bracket within a predetermined angular range causes longitudinal translation of the cam follower, wherein as the door is closed, the cam follower engages the cam surface and translates longitudinally in the second direction whereby the energy stored by the energy storage means is released to assist door closure.

Abstract: A vehicle tailgate assembly comprises a frame with a transverse base and support arms extending perpendicularly therefrom adjacent distal ends of the base, a central section also extending perpendicularly from the base but to a lesser extent than the support arms, a door rotationally mounted to the frame between the support arms, the door being profiled with a central opening matching the central section and aligned therewith in a co-planar manner when the door is in a fully closed position, a mating portion comprising an indentation in the door adapted to mate with the central section when the door is rotated 180 degrees from the fully closed position to a working position to expose the central opening with the door co-planar with the frame.

Abstract: A process for preparing a multi-thickness welded steel vehicle rail, the process comprises the steps of: (a) forming a first tube having a first outer diameter, an inner diameter and a first wall thickness; (b) forming a second tube having the first outer diameter, a second inner diameter and a second wall thickness different than the first wall thickness; (c) swaging a first end of the first tube to a second outer diameter less than the second inner diameter of the second tube; (d) inserting the swaged first end of the first tube into an end of the second tube to form a joint; (e) welding the first tube and the second tube together to form a weld at the joint to form a tube blank with a heat affected zone of lower metal strength in the area of the weld; (f) preheating the tube blank to create a common crystalline microstructure along a length of the tube blank; (g) introducing the tube blank into a blow molding tool having inner molding walls; (h) molding the tube blank at an elevated temperature by expanding the tube blank against the inner molding walls of the molding tool by injecting a pressurized medium into an interior cavity of the tube blank; and (i) quenching the tube blank by replacing the pressurized medium with a cooling medium through the molding tool and the tube blank to achieve a rapid cooling effect on the tube blank and to create a completed vehicle rail with essentially uniform material strength across the weld. A completed vehicle rail has an overlapped welded structure and uniform microcrystalline structure along the length of the rail.

Abstract: A selectively switchable dual rate vehicle suspension system comprising a pushrod actuated inboard spring configuration, conventionally oriented between the unsprung mass and the sprung mass of one corner of the vehicle, comprising a torsion bar spring of a first predetermined rate, K1, and a coil spring of a second predetermined rate, K2, arranged in series so as to provide a total combined spring rate KT. A lockout actuator is arranged in parallel with the coil spring and configured so that in a first mode it allows the coil spring to move freely and in a second mode prevents motion of the coil spring such that when the lockout actuator is in a first, unlocked, mode the overall vehicle suspension spring rate is defined by the series equation 1/KT=1/K1+1/K2, and when the lockout actuator is in a second, locked, mode the overall vehicle suspension spring rate is substantially higher as defined by KT=K1, thus selectively providing both a low rate, optimal ride comfort setting and a high rate, optimal handling setting.

Abstract: A method of operating a vehicle door includes the step of pushing an unlatched door to an ajar position. The unlatched door is mechanically held in the ajar position. In one embodiment, the method is performed using a door presenting system that includes a door checker that is configured to hold a door in the ajar position. A presenting actuator is movable between retracted and extended positions. The extended position corresponds to the ajar position. A controller is configured to move the presenting actuator between the retracted and extended positions in response to a presenting signal.

Abstract: A pedestrian protection automotive hinge includes a release assembly which includes a clip supported at one of the first and second ends and a stop pin supported by the other of the one of first and second members. The stop pin is captured in the clip in the normally closed position and the normally opened position. The stop pin is configured to break the clip in response to a collision input permitting the second member to pivot about a member pin relative to the first member to an opened hood collision position and the stop pin to move to a second end of a slot. An actuator is configured to engage the second member and move the second member upward relative to the first member in response to the collision input and break the clip.
