A horn actuating device for a motor-vehicle steering-wheel comprises a plurality of spring (8) which resiliently support an actuating element (20) constituted by the housing of the air-bag associated with the steering-wheel or a covering element for the steering-wheel hub. The springs (8) define movable electric contacts (26) adapted for co-operation with fixed electric contacts (17) for actuation of the horn. All these contacts are connected to electric conductive strips (14, 16) embedded in a flexible strip (15) of plastic material which is connected to supports (10) also made of plastic material, on which the above mentioned springs (8) rest. The actuating element (20) is provided with studs (21) guided within bushes (22) forming part of said supports (10) of plastic material. The studs (21) are held at the lower end by elastically deformable stop means which enable a rapid installation of the air-bag unit or the hub covering element on the steering-wheel frame. <IMAGE> |
