Abstract: A vehicle safety system target includes a first platform disposed on a mobile chassis, a frame assembly, a first securing member, a second platform, and a mounting member. The frame assembly is at least partially disposed about the mobile chassis and includes a first frame member and a second frame member. The first frame member is disposed on the first platform. The second frame member is disposed on the first platform. The first securing member is configured to couple an object to the first platform. The second platform is spaced apart from the first platform. The mounting member is disposed on the second platform.

Abstract: The present disclosure provides a sway bar for a suspension system of a motor vehicle. The sway bar includes a first lever arm for attachment to a left wheel suspension component and a second lever arm for attachment to a right wheel suspension component. The sway bar further includes a torsion spring device in connection between the first lever arm and the second lever arm to provide variable torsional stiffness. The torsion spring device includes a first torsion bar, a second torsion bar, and a clutch connected to the first torsion bar and the second torsion bar. The clutch is configured to move between a disengaged position and an engaged position where both of the first and second torsion bars transmit torque between the first and second lever arms to provide torsional stiffness.
