Abstract
A hinge and bracket system for a cushion seat back is provided. A bracket is attached to the side of a cushion seat back which is laying flat. The bracket is connected to a rotatable shaft, which in turn is connected to a toothed gear and a pawl. When the cushion seat back is raised upward, the toothed gear and an element of the pawl allow the cushion seat back to ratchet upwards, with the capability to lock the cushion seat back at any tooth. When the cushion seat back is raised above about 90 degrees, the pawl is forced to disengage from the toothed gear and the cushion seat back is unlocked and can be placed back in the original flat position. This hinge and bracket system may be employed in marine operations, especially for water skiing.
