Abstract

A safety belt connecting structure includes first and second shoulder belts, and an adjusting belt. The first and second shoulder belts have corresponding first and second shoulder belt coupling ends and first and second shoulder belt connecting end, and the first shoulder belt engaging end is coupled to a facility where the safety belt connecting structure is installed. The second shoulder belt coupling end is coupled to the facility. The adjusting belt has an adjusting belt connecting end and an adjusting belt adjusting end. The adjusting belt connecting end is connected with the first and second shoulder belt connecting ends, and the adjusting belt adjusting end is adjustably fixed with a positioning portion on the facility, so that an acting length of the safety belt connecting structure with respect to the facility is adjustable by adjusting a position of the adjusting belt with respect to the positioning portion.

First claim

What is claimed is:

1 . A safety belt connecting structure, comprising:
a first shoulder belt having a first shoulder belt coupling end and a first shoulder belt connecting end, the first shoulder belt coupling end being coupled to a facility where the safety belt connecting structure is to be installed; a second shoulder belt having a second shoulder belt coupling end and a second shoulder belt connecting end, the second shoulder belt coupling end being coupled to the facility; and an adjusting belt having an adjusting belt connecting end and an adjusting belt adjusting end, the adjusting belt connecting end being fixedly connected with the first shoulder belt connecting end and the second shoulder belt connecting end, and the adjusting belt adjusting end being adjustably fixed with a positioning portion on the facility, so that an acting length of the safety belt connecting structure with respect to the facility is adjustable by adjusting a position of the adjusting belt with respect to the positioning portion; wherein each of the first shoulder belt and the second shoulder belt extends obliquely at its respective upper half, and then gradually transitions to vertically extend at its respective lower half.

2 . The safety belt connecting structure according to claim 1 , wherein:
the lower half of the first shoulder belt includes the first shoulder belt connecting end, and the lower half of the second shoulder belt includes the second shoulder belt connecting end.

3 . The safety belt connecting structure according to claim 1 , wherein:
the adjusting belt connecting end, the first shoulder belt connecting end and the second shoulder belt connecting end are sewn together at a fixing area where they intersect with each other.

4 . The safety belt connecting structure according to claim 3 , wherein:
the fixing area is configured to be substantially subjected to a vertical tension without a lateral tension to reduce a risk of the first shoulder belt and the second shoulder belt at the fixing area being pulled apart.

5 . The safety belt connecting structure according to claim 1 , wherein:
each of the first shoulder belt, the second shoulder belt and the adjusting belt comprises an independent belt, and the first shoulder belt connecting end, the second shoulder belt connecting end and the adjusting belt connecting end are stacked with each other and fixed to each other at a stacked position.

6 . The safety belt connecting structure according to claim 5 , wherein:
the adjusting belt connecting end is stacked between the first shoulder belt connecting end and the second shoulder belt connecting end.

7 . The safety belt connecting structure according to claim 5 , wherein:
the first shoulder belt connecting end and the second shoulder belt connecting end are attached to each other, and the adjusting belt connecting end is stacked at a side of either of the first shoulder belt connecting end and the second shoulder belt connecting end that are attached to each other.

8 . The safety belt connecting structure according to claim 1 , wherein:
one of the first shoulder belt and the second shoulder belt is integrally formed together with the adjusting belt as a single belt, and the other of the first shoulder belt and the second shoulder belt is formed as another single belt, a part of the single belt corresponding to the first shoulder belt connecting end or the second shoulder belt connecting end and a part of the another single belt corresponding to the second shoulder belt connecting end or the first shoulder belt connecting end are fixedly connected with each other.

9 . The safety belt connecting structure according to claim 1 , wherein:
the first shoulder belt and the second shoulder belt are formed as a single belt, and the adjusting belt connecting end and a middle part of the single belt are fixedly connected with each other, wherein the single belt is divided into a first half corresponding to the first shoulder belt and a second half corresponding to the second shoulder belt by the middle part of the single belt.

10 . The safety belt connecting structure according to claim 1 , wherein:
a length from the first shoulder belt coupling end or the second shoulder belt coupling end on a front side of the facility to the adjusting belt connecting end on a rear side of the facility is non-adjustable.

11 . A child safety seat comprising:
a seat body; a safety protective portion at front of the seat body and configured to secure a passenger on the child safety seat; the safety belt connecting structure according to claim 1 is installed on a back of the seat body; wherein a lower end of the safety protective portion is coupled to the seat body, an upper end of the safety protective portion is connected to the first shoulder belt coupling end and the second shoulder belt coupling end of the safety belt connecting structure through a corresponding hole on the back of the seat body, and the belt adjusting end of the safety belt connecting structure is coupled to the seat body.

12 . The child safety seat according to claim 11 , wherein:
the safety protective portion comprises a first shoulder pad, a second shoulder pad and a crotch protector; and an upper end of the first shoulder pad and an upper end of the second shoulder pad are coupled to the first shoulder belt coupling end and the second shoulder belt coupling end of the safety belt connecting structure respectively, a lower end of the first shoulder pad and a lower end of the second shoulder pad are coupled to an upper end of the crotch protector through a connector respectively, and a lower end of the crotch protector is coupled to the seat body.
