Description

Four-point child safety belt

technical field

The utility model belongs to the field of automobile installation, in particular to a four-point safety belt for children.

Background technique

The safety of child occupants on school buses and other vehicles has become one of the issues that are highly valued in China. In particular, several vicious school bus accidents in 2011 caused widespread social concern and controversy. The safety performance of school buses and the protection of child occupants have also become one of the focuses of controversy. Most of the safety belts used on school buses are simple two-point safety belts. For example, Chinese patent CN203142605U discloses a two-point safety belt for children. The comfort is not enough when using this two-point safety belt. Lack of protection for the torso and head of the child's upper body, in an emergency, the child's upper body leans forward and easily bumps into the front seat, causing danger. The three-point safety belt used by adults is not suitable for children because of the concentrated force on the shoulders and chest of children.

Relatively speaking, four-point seat belts are more suitable for children. However, there are some deficiencies in existing four-point safety belts. For example, the process of using the four-point safety belt disclosed in Chinese patent CN102490678A is more complicated. It needs three times to untie or insert the buckle to use or untie the safety belt, which is inconvenient to use and difficult to untie the safety belt to escape when danger occurs. Because the two shoulder straps are connected to a retractor at the same time, it is inconvenient to adjust the length of one side, and the scope of application is limited. Chinese patent CN201227981Y also discloses a four-point safety belt, which cannot protect children's upper torso well and has poor safety.
