Abstract

A seat has a seat element and a back element which is to be tiltable forwardly and rearwardly relative to the seat element. Two hinges are provided at the opposite sides of the seat and each includes a first hinge member on the seat element and a cooperating second hinge member on the back element. Each hinge has an arrangement which connects the first and second hinge members thereof for relative pivoting and which includes a first gear turnable with one of the hinge members and a second gear turnable with the other hinge member, the two gears having cooperating annuli of gear teeth which mesh with one another. One of the gears can be disengaged from its associated hinge member so that the latter can turn freely relative to this gear. The arrangement for this purpose includes a first abutment system which normally connects the gear to the associated hinge member, and a second abutment system which also normally connects the gear to the associated hinge member. One operating arrangement permits the first abutment system to be disengaged so as to permit the associated hinge member and hence the back element to pivot forwardly and another operating device permits the second abutment …
