Abstract
A vehicle seat comprises a head rest tilt mechanism which supports a head rest, a pressure receiving member contained in a seat back, and a speed increasing unit. The pressure receiving member moves rearward when it is pushed by the body of an occupant. The speed increasing unit has a base bracket, first and second arms, a roller, a pulley, etc. A part of a wire is wound in the shape of a U around the pulley. When the pressure receiving member moves rearward, the pulley moves to pull the wire. When the wire is pulled, the head rest tilt mechanism is driven to move a head rest body forward.
