An elastic coupling unit is arranged on an element of a motion transmission assembly. The motion transmission assembly includes at least one cardan joint on one extremity and an input plate and an output plate between which an elastic member is located. The elastic member and the annular face portions of each of the input and output plates are concave in shape so that the elastic member works together with the annular face portion of each plate. The concavity center of these various portions matches the conical rotation center of the assembly and is located on the output plate side of the center.

Elasting coupling unit especially for a vehicle steering column

Safety assembly for a separable coupling device, particularly for a motor vehicle steering column having two coaxially arranged shaft sections whose end portions are offset with respect to their common geometric axis and which overlap. Each shaft section carries a plate. Each plate is connected to the other plate by separable link pins. The safety assembly comprises a clip made up of a fork having two faces connected to each other by a web so that each of the two faces bears against one side of a corresponding plate:
