Abstract: A safety device that engages automatically when a child is placed in a shopping cart. It does not require the aid of a parent. A torsion spring retains a shopping cart seat at an inclined angle, while retaining the safety device to the rear of the shopping cart, free for the child to enter. As the child is placed in the cart, his/her weight descends the seat to normal. A lever is under the seat rotating downward as the seat descends. The lever is welded at the center of a shaft, and is rotating the shaft as the lever moves. A right arm and a left arm welded to the shaft are traversing forward to a securing position. Connected near the top end of the two arms is a safety bar securing the child when seated. A latch locks the arms in the securing position. The entire safety device is mounted to the shopping cart with a clamp. There are four clamps used. When two clamps are connected together they form one clamp with three horizontal holes.
