Detachable cantilevered headrest having a ratchet mechanism

An adjustable and detachable cantilevered headrest assembly adapted to be mounted on a vehicular seat comprising:

• a horizontally extending mounting post adapted to be attached to the vehicular seat;
• an elongated headrest body extending horizontally between opposing first and second side ends and defining a tubular opening receiving said mounting post therethrough between said first and second side ends, said first side end including a cavity formed integrally with said headrest body;
• a ratchet mechanism disposed within said cavity of said first side end and operatively connected between said mounting post and said headrest body for providing forward ratcheting pivotal movement of said headrest body relative to said mounting post while locking said headrest body against pivotal rearward movement;
• said mounting post including a distal end extending from said tubular opening in said first end of said headrest body, a proximal end extending to said second side of said headrest body;
• and a raised ridge extending between said distal and proximal ends, said ridge including a notch;
• and
• an elongated headrest guide sleeve having a tubular opening receiving said distal end of said mounting post to detachably connect said headrest assembly to the vehicle seat, said guide sleeve including a detente selectively received into said notch of said raised ridge of said mounting post to prevent said mounting post from being removed from said guide sleeve, said detente also selectively released from said notch of said raised ridge to remove said mounting post from said guide sleeve.
