Description

Sliding adjusting and locking system for child safety heightening pad

Technical Field

The utility model relates to a child safety seat, in particular to a child safety heightening pad.

Background

The automobile safety belt is designed according to the height and the body shape of an adult, and the automobile safety belt can be used by children only with the height of more than 1.4m (about 12 years old) due to the height. For this purpose, the child safety seats of Group23 are commercially available, usually for children aged 3-12 years, which are converted into child seats by adding the child seats to the original adult seats. The child safety seat has the main purpose of raising the sitting position of the child and avoiding the seat belt from tying the neck and the abdominal cavity. The Group23 child safety seats come in a variety of forms, generally classified as highback booster seats, low back booster cushions, and single base booster cushions, wherein:

the high back heightening seat is provided with a headrest and side wings besides a heightening cushion for lifting the riding position of the child, the opposite sides of the high back heightening seat are bumped with better protection effects, and the product is authenticated by i-Size, so that the high back heightening seat has higher safety and riding comfort; but the price is more expensive, the weight (about 8-9 Kg) and the volume of the product are larger, and the occupied space in the vehicle is more; especially, the disassembly and assembly switching between the adult riding position and the child riding position are time-consuming and labor-consuming.

The product of the low back heightening pad is relatively light (about 5 Kg), comprises the heightening pad for lifting the riding position of children and the lumbar support, thus having certain comfort, smaller volume, less occupied space in a vehicle and relatively low price; but it does not have side protection and i-Size authentication. And the short back heightening pad also occupies an adult seat after being installed, so that the disassembly and assembly switching between the adult seat and the child seat are time-consuming and labor-consuming.

The single-base heightening pad is very light (2-3 Kg), and the main body of the single-base heightening pad is a heightening pad for lifting the sitting position of a child and is connected with a car seat through a standard interface; the single-base heightening pad has the advantages of smaller volume, less occupied space in the vehicle and very low price; but it also does not have side protection and i-Size authentication, and is less comfortable without lumbar support. For the position of the single-base heightening pad, the higher riding position is lifted, so that the adult riding is inconvenient, and the single-base heightening pad needs to be disassembled and assembled when the adult riding position and the child riding position are switched.

Therefore, the existing child safety seat has the technical problem that after the child safety seat occupies an adult sitting position to form a child sitting position, the two sitting positions cannot be quickly and simply switched; it is obvious that solving this technical problem is a long-standing actual demand in the market.

For the single-base booster pad therein, the technical feasibility of rapidly switching it between the adult-sized seating position and the child-sized seating position is relatively higher because of its relatively simple structure in three child seats. In the prior art, the foldable high-back heightening seat is provided, and the cushion part of the seat can be folded relative to the backrest in a turnover way, so that the seat can be conveniently stored. The overturning and folding of the cushion part provides a reference for the rapid switching of the heightening cushion with a single base.

In practice, researchers want to connect single-base booster pads with standard interfaces in a rotary folding manner, and form child seats when the booster pads are tiled on the seat cushion of the automobile seat; when the heightening pad is turned over and then is attached to the backrest of the automobile self-seat, an adult sitting position is formed, and the heightening pad is converted into a waist support. On the basis, the designer also needs to add additional functions of the heightening pad; for example, the expansion and contraction adjusting function of the heightening pad in the height direction is added to adjust the thickness of the heightening pad; for another example, after the heightening pad is converted into the waist support, a wing plate which slides left and right is additionally arranged on the waist support so as to adjust the supporting width of the waist support; these additional functions are all required to be performed by means of sliding fittings, and how to unlock/lock these sliding fittings relates to whether the relevant function can be used normally.

Disclosure of Invention
