Abstract

A cushioning device (10, 10.1) for rotatable components such as, for example, roof grab handles or sun vizors of a vehicle, having an outer rotational sleeve (14) and an inner rotational part (12), which are both arranged in a manner such that they can rotate relative to each other about a common axis of rotation (16) from a first rotational position into a second rotational position, either the inner rotational part (12) being fixed and the outer rotational sleeve (14) being rotatable or the outer rotational sleeve being fixed and the inner rotational part being rotatable, is distinguished in that the outer rotational sleeve (14) has, on its inner contour, an inwardly pointing inner stop (20), and the inner rotational part (12) has, on its outer contour, an outwardly pointing counterstop (26) which consists of soft material, reduction of the inner radius (R:R1) of the inner contour of the outer rotational sleeve (14) in the region in front of the inner stop (20) enabling the outer contour of the counterstop (26) to come increasingly more strongly into contact with the inner wall of the outer rotational sleeve (14) during rotation from the first into the second position, as a resul…
