Abstract
A locking shaft extends through passages in a mounting bracket, a seat bracket and a seat cover bracket to prevent small children from raising the seat and seat cover. The locking shaft and a plunger are mounted to an end cap with the plunger being slidable within an axial passage in a rod upon which the brackets are mounted. A spring connected to the plunger inside the axial passage biases the locking shaft toward a locked position. In order to unlock the seat and seat cover, a person must pull the locking shaft out of the passages in the seat bracket and the seat cover bracket and raise the eat and seat cover, or just the seat cover if so desired, after placing the locking shaft in the unlocked position.
