Abstract: A motor support comprises two coaxial rings (20; 22) and an element for limiting the tilting of the inner ring relative to the outer ring. The limiting element comprises a finger (26) projecting from a first of the rings (20; 22) and housed in a receptacle (28) in the second of the rings (20; 22). An axial end-stop in the receptacle (28) limits the movement of the finger (26) in the receptacle (28) in the direction of the common axis (A) of the two rings (20; 22). The axial end-stop comprises a spigot (32) extending from a base (38) of a peg (36) through a wall (45) of the receptacle. The base (38) of the peg (36) is fixed to the second ring. The spigot (32) has a projection (44) capable of abutting against the wall (45) of the receptacle (28).

Abstract: The motor support (16) comprises an inner ring (20) able to receive an element of the motor and an outer ring (22) able to be fastened to a housing, and a means (24) of decoupling between the two coaxial rings (20; 22) comprising a plurality of pads (46) of elastomer material that are interposed between the inner ring (20) and the outer ring (22). Each pad (46) is substantially “H”-shaped in form. The two arms (46int, 46ext; 461, 462) of the «H» are separated by a distance B. Each arm (46int, 46ext; 461, 462) has a width D measured in the radial direction. The web (46a) of the “H” has a width A measured in the orthoradial direction. The ratio A/B B is greater than or equal to 1.4, and the ratio A/D is greater than or equal to 2.

Abstract: The invention relates to a control module (4) for an electric appliance (3), comprising: a printed circuit board (11), on which electrical and electronic components (12) are mounted; and an electronic power component (10) separated from the printed circuit board (11) and held in relation thereto by means of at least one electrical connection body (18a, 18b, 18c) fixed to the printed circuit board (11) and connected to one (D) of the terminals (S, D, G) of the electronic power component (10).

Abstract: The invention relates to auxiliary electric heating equipment for a motor vehicle, comprising one or more heating bars comprising resistances with a positive temperature coefficient, and an electronic power stage alternately powering each heating bar on and off, according to a cyclic ratio that can be adjusted by control means. This equipment comprises means for limiting the actual intensity of the current passing through the electronic power stage, by measuring the peak current passing through at least one heating bar and comparing the measured peak current value with a peak current value read in a table for the current cyclic ratio, and decreasing the cyclic ratio if the measured peak current exceeds the peak current value read in the lookup table. The peak current value read in the lookup table corresponding to the maximum actual current allowable by the control unit for the cyclic ratio in question.
