  • Patent number: 6663174
    Abstract: A passenger chair which can be converted into a child chair, including a floor frame, a passenger back rest with side members which are linked with rear side portions of the frame for tilting the passenger back rest backwards and forwards, the passenger back rest having a first flap the top of which is linked with an upper portion of the passenger back rest and a second flap with a first end portion which is linked with a lower end portion of the first flap. The passenger chair has a mechanism which, when the passenger back rest is moved forwards, effects a forcible rotation of the second flap to an approximately horizontal position, while at the same time the first flap is moved forwards. The first flap thereby forms a back rest and the second flap a seat of a child chair which faces in the opposite direction relative to the passenger chair.
