An electric rocking chair equipped with an electric device engendering automatically an in and out movement of the chair without there being a push by the user. The chair includes an armature deposited on the top of a support base containing a displacement device. The armature is fixed to the base in pivots allowing to move the chair front to back by means of a seesaw operation. The device includes an electric engine coupled with a reducer at the output of which is fixed a wheel to which a belt causes the moving of a horizontal arm with an elbow which acts on the armature so as to produce the in and out movement of the chair. A control lever within reach of a user allows to command the engine and to engage the in and out movement or to stop it. Another version involving a cam arrangement is provided. |
