The elastic support consists of two structures (3,4) one disposed inside the other and of which, between the lateral walls, are interposed elastic material cushions (6,8,12). The lateral walls (4a) of the exterior structure (4) carry inclined dished projections (14) onto which can progressively come to stop the elastic cushions (12) adhering onto the lateral wall (3a) of the interior structure (3). This method of support prevents a complete pulling out of one structure (3) from the other (4), under the effect of a force which moves the walls parallel one to the other. This is effected by part of the mass of elastic material, fixed to the other lateral well (3a) of the of the internal structure (3) facing the projection (14), becoming wedged under this projection. |
