1. A protective bellows for a shock absorber rod in particular for a motor vehicle, of the type comprising at least two concentric corrugated elements (5, 6) of different diameters which are connected together by an intermediate spacer member (7) characterised in that the spacer member (7) is a rotationally symmetrical diaphragm which is capable of being turned over from its production shape to its functional position in which it is disposed substantially at the centre of the available space between the corrugated elements (5, 6) which in the condition of extension of the bellows are in axial relationship, said spacer member (7) being fixed by means of one of its ends to the closest turn of the element (5) of large diameter by way of a thin zone (8) which is normal to the axis of the bellows, with which it forms a curve (R3) which is curved inwardly followed by a reversed inflection portion (R2) which connects it to a central tubular body (10) of the spacer member (7), the other end thereof being connected by a curve (R1) to the end turn (11) of the small-diameter element (6) whose free end is fixed with respect to the rod (2), in such a way that when the elements (5, 6) are closed up with their turns touching, the total height of the bellows substantially corresponds to that of the spacer member (7). |
