A safety device is characterized is made by a chamber ( 1 ) of flexible walls filled with air and a nipple ( 5 ) to facilitate the progressive outflow of the air when the chamber ( 1 ) is highly pressed. The nipple ( 5 ) has a valve ( 6 ) to prevent the accidental outflow under low pressures of the air occupying the chamber ( 1 ) and to give way when receiving a high pressure thereby facilitating the outflow of the air. The chamber ( 1 ) is preferentially subdivided into several departments ( 2, 3 and 4 ) each of them having a nipple ( 5 ) for the outflow of the air. The chamber ( 1 ) and the valve ( 6 ) are arranged in the inside of the complementary side members ( 7 ) of the backrest ( 8 ) of the infant seat and in the complementary side members ( 9 ) of the headrest ( 10 ) of the backrest.
