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 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: An automotive lift-off hinge joint to rotationally connect an automotive door and body comprises first and second door side hinge brackets and a body side hinge bracket. A detent shaft is provided with an interiorly threaded intermediate portion adapted to receive a removable threaded fastener and with a shaped detent shaft feature adapted to engage a similarly shaped pyramidal portion of a guide pin fastened to the body side hinge bracket. The detent shaft is rotationally mounted within a cylindrical check mechanism and secured in relation to the first and second door side hinge brackets. Bushings in door side hinge bracket apertures allow rotation of portions of the detent shaft extending through the apertures. The pyramidal shaped portions are preferably square.

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 handle assembly is used with a pick-up truck tailgate. The handle assembly comprises a guide tube with an open end, a handle that is housed within the guide tube and a pivot assembly. The pivot assembly comprises a pivot pin connected to one end of the handle and a locking pin. The handle is moveable within the guide tube between a retracted position and an extended position. While in the extended position the handle passes through the open end and the handle may pivot about the pivot pin to move to a support position. When the handle is in the support position, the locking pin can engage the handle and releasably lock the handle in the support position. The guide tube is configured to be secured within a tailgate of a pick-up truck.

Abstract: A bumper for a closure, such as a tailgate, acts between the tailgate and a frame to bias a striker in to engagement with a latch. The bumper is moved to a retracted position during closing to reduce the force needed to close the tailgate. After latching, the bumper is conditioned to an extended position to assert the bias between the tailgate and frame.
Abstract translation: 用于闭合件的保险杠（例如后挡板）作用在后挡板和框架之间，以将撞针偏置成与闩锁接合。 保险杠在关闭期间移动到缩回位置，以减少关闭后挡板所需的力。 在锁定之后，保险杠被调节到延伸位置以断定后挡板和框架之间的偏压。
