A hook member of a vehicle seat lock engages with a striker fixed to a vehicle body. An opening lever is pivotally secured to the first base plate to constitute the first subassembly. The hook member is pivotally secured to the second base plate to constitute the second subassembly. The first base plate is coupled to the second base plate. Between the first and second base plates, a sensing member is pivotally secured in parallel with the hook member to detect invasion of the striker in the hook member.

Vehicle seat lock

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.

In a vehicle seat lock, a striker is mounted to a vehicle body and a hook member is mounted to the seat back. The striker comprises the first and second engagement portions which selectively engage in first and second engagement grooves of the hook member to hold the seat back in two kinds of standing positions. The hook member is pivotally secured on a pivot to open and molded with synthetic resin to buffer impacting of the striker.

A seat back lock is included in a seat back of a vehicle. A knob is provided at the top of the seat back. A passenger in the vehicle pushes down the knob to cause the seat back to move from a standing position to a folding position on a seat. In the standing position, a striker extending from the body of the vehicle engages with a hook of the seat back lock. The seat back lock comprises a binding lever and a warning lever connected to the knob. Whenever the strike engages with the hook, the binding lever directly contacts the striker. If the striker incompletely engages with or disengages from the hook, the knob is pulled down by the warning lever to expose an indicator to permit the passenger to visually recognize it.
