Abstract
A device for adjusting a double-jointed seatback by a single control. A seat pan structure is joined on at least one side to a convex toothed sector centered on a first joint. A seatback structure is joined to two arms that extend on either side of a housing. The arms are articulated on a second joint mounted upon the housing, and are joined to a concave toothed sector centered on the second joint. The housing contains an upper toothed locking plate and a lower toothed locking plate. Between the two locking plates, a pivoting cam connects to a single control device. The upper toothed locking plate is joined to a stop arm that extends in the housing towards a semicircular stop located on the lower toothed sector. The semicircular stop is provided to resist the unlocking of the locking plate except when the seatback is in the maximally advanced position.
