ABSTRACT:
A hinge for a backrest of a seat in which the backrest can pivot between an upright position and a horizontal position and in which the backrest can be latched at one edge in the upright position. The hinge includes a first member securable to an opposed edge of the backrest; a second member securable to a vehicle body; a third member positioned between the first and second members; a fourth member positioned adjacent the third member below the first member; a first pin secured to the third member about which the first member can pivot; a second pin secured to the second member about which the third member can pivot; a third pin secured to the third member about which the fourth member can pivot; and a fourth pin secured to the second member about which the fourth member can pivot; wherein the axes of the pins are parallel; wherein the edge of the first member toward the fourth member has teeth; and wherein the edge of the fourth member toward the first member has teeth. The positioning of the pins is such that when force is applied to the first member in a direction to move the backrest to the horizontal position while the backrest is latched in the upright position, the first pin moves the third member about the second pin, whereby the third pin moves the fourth member about the fourth pin to bring the teeth on the first and fourth members into locking engagement.
