Image Number 5 for United States Patent #8113137.
A movable seat and backrest are coupled by a pivoted link system, allowing the seat to pivot from a raised stowed position to a lowered use position. A connecting link is coupled to one of the pivoted seat links, such that, as the seat is lowered, the connecting link raises the backrest. When the seat is raised to a stowed position, the connecting link lowers the backrest to a lowered position. When mounted in a vessel, the backrest forms part of the bolster system when the seat is stowed.
