ABSTRACT:
A damping apparatus for retarding motion of a movable body is disclosed. The apparatus has a damper unit with at least two rollers having resilient peripheral surfaces. The rollers are free wheeling relative to one another and roll along a guide in contact with opposite guide surfaces. The damper unit further includes a carrier rotatably carrying the rollers. The carrier is operably connectable to the movable body such that a force is applied to the carrier in response to motion of the body to urge the rollers against the guide surfaces at an intensity which progresses in relation to the magnitude of the applied force to resiliently compress the resilient peripheral surfaces against the guide surfaces as the rollers rotationally travel therealong, to retard motion of the body.
