Abstract
An exemplary latching system includes, among other things, a striker, a latch assembly that engages the striker to transition the latch assembly to a latched position, and a bumper containing rheological material. The bumper contacts the striker when the latch assembly is in the latched position. An exemplary latching method includes, among other things, contacting a striker with a bumper when a latch assembly engages the striker in a latched position, and increasing a hardness of the bumper by aligning particles within rheological material of the bumper.
