Problems solved by technology
This structural feature makes the position restraint of the auxiliary belt on the shoulder safety belt very unreliable. When an accident occurs, the huge tension on the shoulder safety belt makes the joint between the auxiliary belt and the shoulder safety belt slide, making the shoulder safety belt Allows for more forward travel and thus cannot provide effective restraint protection for child occupants
What's more dangerous is that the sliding of the joint may cause the shoulder belt to move up, causing injury to the child's neck
At the same time, the stress position of the shoulder seat belt is concentrated on the side edge of the soft belt, which is easy to cause damage to the soft belt and cause the failure of the seat belt.

Embodiment Construction
[0073] The specific implementation will be described below in conjunction with the accompanying drawings.
[0074] figure 1 and figure 2 An embodiment of the seat belt system of the present invention is shown.
[0075] In this embodiment, the child occupant uses an auxiliary restraint belt to adjust the height of the restraint point on the shoulder belt while wearing the adult three-point seat belt.
[0076] One end of the three-point seat belt (1) shown in the figure is fixed on the fixed point (6) of the vehicle body, and the other end is guided by the seat belt guide (8), and then wound on the safety belt fixed on the vehicle body. on the belt retractor (7). A tongue (9) is slidably supported on the soft belt (1). A belt buckle (10) is fixed on the car body. When the occupant wears the seat belt (1), insert the tongue (9) into the buckle (10) and lock it. The soft belt (1) is tightened under the effect of the retractor (7) and supported on the occupant's body. At t...

The invention relates to a restraint belt buckle suitable for a seat safety belt system and capable of being detachably combined with a shoulder safety belt and locked to form a seat safety belt system capable of limiting the upper restraint height of the shoulder safety belt. The restraint belt buckle comprises a belt buckle body and a soft belt pull rod. The belt buckle body is provided with a channel for the insertion or the removal of a soft belt (a shoulder safety belt) after being folded up. The front end of the belt buckle body is provided with an insertion port of the channel, while the rear end of the belt buckle body is provided with a belt connecting part. When the soft belt and the restraint belt buckle are inserted into each other to be locked, the soft belt pull rod passes through a crevice formed through the folding of the soft belt so as to be crosswise arranged across the belt buckle body. Thus, the soft belt pull rod is supported by the pull rod supporting structure of the belt buckle body.
Description
technical field [0001] The present invention relates to a seat belt system for a vehicle. . Background technique [0002] Currently, seat belt devices on vehicle seats are widely used. When an accident such as a collision occurs, using the seat belt to restrain the occupant to prevent the occupant from flying out of the seat can protect the occupant. [0003] There are various types of seat belt devices, such as a shoulder belt that restricts movement of the occupant's shoulders and chest, and a lap belt that restricts movement of the occupant's waist. The most commonly used is the three-point seat belt device, which has a soft belt, one end of which is fixed on the vehicle body, and the other end is guided by the seat belt guide, and wound around the safety belt fixed on the vehicle body. with retractor on. A tongue is slidably supported on the soft belt. A buckle is fixed on the vehicle body or the seat. When the occupant wears the seat belt, insert the tongue in...
