Description

A hip seat carrier

The present invention relates to a hip seat carrier which is supported by a waist of a guardian while holding it against a baby by a guardian, and contacts a heap seat that seats the baby in front of the guardian.

Recently, in order to give a protector a baby hug, the protector uses a hip sheet instead of a traditional cloak to place the baby around the protector's upper body and hug the baby face to face. The swimwear loosens the knot of the swimwear cord around the back of the caregiver due to the load of the baby while the baby is placed on the back of the caregiver for a long time so that the baby gradually flows down from the back of the caregiver.

Alternatively, the heel seat is supported by the waist of the protector so as to face the baby on the protector's chest and seats the baby on the protruding heel seat, so that the baby is placed on the chest of the protector for a long time Do not let the baby flow from the chest of the guardian. Therefore, the heap sheet makes the guardian-baby connection more smooth than the wrapping cloth, and makes the caring environment for the baby more stable than the wrapping cloth.

Further, the heap sheet is supported on the shoulder of the protector as well as the back of the protector, and is deformed into a heap sheet carrier, and the heap sheet carrier is distributed in various types in the baby goods market. On the other hand, the heap sheet carrier is disclosed in Korean Patent Registration No. 10-1359888. The heap seat carrier includes a seat portion, a hug pad, and a scabbard portion.

However, as a technical problem of the above-described heap seat carrier, the heap seat carrier firstly performs various attachments by performing detachment / attachment of the seat portion and the hug pad, detachment / attachment of the hug pad and the sagittal portion, and / It is deformed to surround the upper body of the protector, but it takes a long time to be worn on the upper part of the protector due to the repeated operation of detachment, thereby increasing the burden on the protector.

Secondly, the heap sheet carrier should be used to store unused components after the detachment of the seat portion and the hug pad, the detachment of the hug pad and the shoelace portion, and / or the detachment of the seat portion and the shoelace portion, Which would result in the loss of unused components and additional purchases.

The heap seat carrier has to use belts, buckles, open fasteners and buttons as belts to detach and attach the seat portion and the hug pad, detach and attach the hug pad and the shoelace portion, and / The repeated operation of detachment during lifetime promotes deterioration of the belt, buckles, open fasteners and buttons, deforming from the initial shape and poor external appearance.

As a problem of the application of the heap seat carrier, the heap seat carrier firstly provides convenience and convenience to the protector through detachment / attachment of the seat part and the hug pad, detachment / attachment of the hug pad and the shoelace part and / But it does iterative work on the individual shape so that it can be learned by the guardian so that the baby is dropped from the guardian by partially omitting the assembly step according to the degree of learning.

Secondly, the heap seat carrier can freely detach and attach the seat portion and the hug pad, detach and attach the hug pad and the shoelace portion, and / or attach and detach the seat portion and the shoelace portion in the indoor space. However, Or in a pedestrian-crowded area, there is a limit to changing the position of the baby according to a seasonal change or a surrounding situation, because the components can not be smoothly detached and attached.

Thirdly, the heap sheet carrier disperses the load of the baby resting on the seat portion to the back and shoulders of the caregiver to relieve the pain given to the guard's musculoskeletal system. However, according to the baby's weight during the life of the baby, It increases the load on the guardian, which causes the guardian to develop musculoskeletal diseases.
