A magnetic buckling assembly includes a male buckling component, a female buckling component, a first locking portion, a second locking portion, an operating component, a first magnetic component, a second magnetic component and a clearance structure. The first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component. The clearance structure allows the second locking portion to slide an offsetting position for preventing the separation of the male buckling component and the female buckling component after engagement of the first locking portion and the second locking portion.

A child seat includes a base and a seatback movable relative thereto between a retracted position, in which the seatback preferably is flush with a top of the base, and an extended position, in which a sitting area of the child seat is exposed for sitting and in which the seatback serves to support a child's back. The seatback of the child seat preferably includes a seat belt for restraint of a child when seated in the sitting area. A shopping cart includes the child seat. The seatback includes a gate movable between a retracted position, in which the gate preferably is flush with the seatback, and an extended position, in which the gate extends in a generally upright manner and partially blocks leg openings of the basket to keep items from falling there through when the seatback is in the retracted position.

An adjustable tray assembly is configured to span a distance between the handle of a shopping cart to the backrest of the seat area. The assembly is adjustable to different sizes of shopping carts by utilizing an attachment member within a tray portion at the handle that can be located in different positions, and by permitting the pivoting of an arm portion of the assembly. The pivoting nature of the arm portion allows the arm portion to adjust to the different depth of the seat areas and type of cart. A latch is used to secure the arm portion to the backrest of the seat area. A hollowed area is formed in the arm portion for a child to use the seat area.

A male buckling component for a magnetic buckling assembly. The male buckling component comprises a male locking portion having a column structure. The male locking portion comprises an abutting structure at an end of the column structure, and a male engaging structure adjacent to the abutting structure and formed around a circumference of the column structure. An installation chamber is formed inside the male locking portion, and a male magnetic component is installed into the installation chamber so that the male magnetic component is inside the male locking portion of the male buckling component.

A female buckling component for a magnetic buckling assembly. A female locking portion comprises at least one resilient arm and at least one engaging head integrally formed with the at least one resilient arm. The at least one resilient arm drives the at least one engaging head to move when the at least one resilient arm is resiliently deformed. The female buckling component also comprises an installation chamber inside a middle portion of the female buckling component, a female magnetic component installed in the installation chamber, and at least one operating component movably disposed on the female buckling component and coupled to the at least one resilient arm of the female locking portion to resiliently deform the at least one resilient arm and thereby move the at least one engaging head.

Introduced here is a lightweight, foldable seat cushion which can be placed in the shopping cart seat to support a child's legs, and prevent the hard surfaces of the shopping cart, such as bars, from causing discomfort to the child and causing the child to try to get out of the cart. A seat cover can be temporarily attached to the seat cushion. The seat cover can be elastic to allow insertion of the seat cushion. The seat cover can have an image affixed to the seat cover, where the different sections of the seat cover form different sections of the image, such as body and legs. The seat cover can provide friction against the seat cushion, enabling a user to climb out of the seat cushion without sliding.

Introduced here is a lightweight, foldable seat cushion which can be placed in the shopping cart seat to support a child's legs, and prevent the hard surfaces of the shopping card, such as bars, from causing discomfort to the child and causing the child to try to get out of the cart. The seat cushion can attach to the cart using an attachment mechanism such as magnets and/or clasping protrusions, thus preventing the movement of the seat within the cart. The seat cushion can fold for easy storage in a diaper bag. The lightweight, and the compact size of the seat cushion makes the carrying of the seat cushion convenient and effortless.

A magnetic buckling assembly includes a male buckling component, a female buckling component, a first locking portion, a second locking portion, an operating component, a first magnetic component and a second magnetic component. The first magnetic component magnetically attracts or magnetically repulses the second magnetic component during a connecting process of the male buckling component and the female buckling component along a connecting direction. The first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component.
