ABSTRACT:
A coach seat locking mechanism is disclosed which is compatible for use with existing revolving type coach seats. A metallic body having a vertical bore is affixed to one end of the seat lower frame and a locking rod is vertically reciprocal within the bore between an upper, locking postion and a lower, unlocked postion. A pedal arm having a cam is pivotally affixed to the body and is designed for foot operation form an upper, locking position to a lower, unlocked position. Upon depressing the pedal arm, the locking rod is lowered to its unlocked position and simultaneouly, the pedal cam contacts a body affixed extraction arm to transversely move the seat upper frame away from the coach sidewall. A detent is pivotally secured to the body to maintain the pedal arm in its unlocked position. Upon rotating the seat upper frame through one hundred and eighty degrees, the parts are automatically returned to their initial, unlocked positions to thereby prevent seat upper frame rotation even under the most severe or stressed conditions.
