Abstract

In a vehicle seat lock, an operating knob is provided at the top of the seat back of a chair. The operating knob is joined to the inner end of the bell crank at the lower end. The bell crank is pivotally secured to a bracket in the seat back. The outer end of the bell crank has the first and second elongate openings. The upper end of the first connecting rod slidably engages in the first elongate opening, and the upper end of the second connecting rod slidably engages in the second elongate opening. The lower end of the first connecting rod is coupled to a sensing member which detects invasion of the striker. The lower end of the second connecting rod is coupled to an opening lever which allows a hook member to disengage from a striker fixed to the vehicle body.
