1. A motor support for a motor-fan unit of a vehicle ventilation installation, comprising: two coaxial rings including an inner ring able to accept one or more elements of the motor and an outer ring able to be fixed to a housing that forms a structural element; and a decoupling means for decoupling the two coaxial rings a plurality of blocks which are made of an elastomeric material and are interposed between the inner ring and the outer ring, each block being substantially H-shaped, the two arms of the H being separated by a distance B, each arm having a width D measured in the radial direction, the web of the H having a width A, measured in the orthoradial direction, wherein the ratio A/B is greater than or equal to 1.4 and the ratio A/D is greater than or equal to 2, and wherein each block has a thickness C measured in the direction of a common axis of the two rings, the thickness C being greater than or equal to 14 mm, and less than or equal to 16 mm, and/or the distance B is greater than or equal to 3 mm and less than or equal to 6 mm.
