1. A toilet seat assembly comprising:

  • a seat for permitting a user to sit over a toilet bowl of a toilet apparatus; and

    a hinge for pivotally attaching the seat to the toilet apparatus so that the user can manually pivot the seat relative to the toilet bowl between a vertical-upright position and a horizontal-down position, the hinge having a base for attachment to the toilet bowl and a lock which automatically engages when the seat is manually pivoted into the vertical-upright position to prevent the seat from inadvertently pivoting back to the horizontal-down position, the lock including a cam element and a bead which coacts with the cam element to form a detent mechanism, the bead disposed on a horizontal upper surface of the base.
