As shown in fig. 1 to 5, the present utility model provides a safety seat including a seat body 10, a seat belt 20, and a seat belt adjuster 30. In the present utility model, the side on which the child sits is defined as the front side of the seat body 10. The webbing 20 extends from the front side of the seat body 10 to the rear side of the seat body 10, and the webbing adjuster 30 is mounted to the opposite side of the seat body 10. In an emergency, the webbing 20 is supported by the webbing adjuster 30, and the use stroke of the webbing 20 is shortened.

The seat body 10 is provided with a through hole 11 for passing the seat belt 20 therethrough. The seat body 10 is provided with a pressure switch 12, and the pressure switch 12 is wired to a seat belt adjuster 30. When the pressure switch 12 detects a child seat signal, the signal is transmitted to the seat belt regulator 30, and the seat belt regulator 30 is energized. This arrangement allows the belt adjuster 30 to activate energization only when a child is seated, saving electricity costs. The belt adjuster 30 may be powered on by being connected to a vehicle body power supply interface, or by being provided with a built-in battery, an external mobile power supply, or the like.

In the present embodiment, the webbing 20 is a five-point webbing. The five-point type safety belt is restrained by five points which are a crotch point, two points on the waist side and two points on the shoulder. Two harnesses 20 located at the shoulders of the child extend from the front side of the seat body 10 to the rear side of the seat body 10 through the perforations 11 and are connected together at the rear side of the seat body 10. The five-point safety belt covers the main parts of the body of the child, so that the five-point safety belt can disperse and eliminate the pressure brought by the impact on various parts of the body under the same pressure in emergency conditions (such as collision, sudden braking and the like), thereby reducing the damage of the impact on the body of the child in emergency conditions.

As shown in fig. 6 and 7, the seat belt regulator 30 includes a pusher 31 and an adjusting unit 32. The adjusting assembly 32 has a closed state and an open state, and the pusher 31 is used for controlling the switching of the closed state and the open state. In the open state, the adjustment assembly 32 abuts and tightens the seat belt 20.

The adjustment assembly 32 includes a base 321, a swivel mount 322, and a support plate 323. The base 321 has slide grooves 3212 extending in the front-rear direction on both side walls 3211, a push shaft 301 penetrating both side walls 3211 is provided in the slide grooves 3212, and the pusher 31 is connected to one end of the push shaft 301. A fixing pin 3011 is provided on the pushing shaft 301 to limit the pusher 31. One end of the rotating base 322 is rotatably connected to the base 321 through the first rotating shaft 302, and the other end is rotatably connected to the supporting plate 323 through the second rotating shaft 303. One end of the supporting plate 323 is rotatably connected to the rotating base 322 through the second rotating shaft 302, and the other end is connected to the pushing shaft 301.

Referring to fig. 2, 4 and 6, in the closed state, the base 321, the rotating base 322 and the supporting plate 323 are parallel to each other. The base 321 and the rotating base 322 together form a containing space, and the supporting plate 323 is located in the containing space. The pushing shaft 301 is located at one end of the sliding groove 3212 near the first rotating shaft 302.

Referring to fig. 3, 5 and 7, in the open state, the base 321, the rotating seat 322 and the supporting plate 323 form an included angle with each other, and the pushing shaft 301 is located at one end of the sliding groove 3212 away from the first rotating shaft 302. Specifically, the angle between the base 321 and the rotating seat 322 is smaller than 90 °, the angle between the base 321 and the supporting plate 323 is smaller than 90 °, and the angle between the rotating seat 322 and the supporting plate 323 is smaller than 180 °. The base 321, the rotating base 322 and the supporting plate 323 together define an approximately triangular structure, so that the adjusting assembly 32 can provide stable supporting force for the seat belt 20.

In this state, the rotating seat 322 abuts against and tightens the webbing 20. The end of the swivel seat 322 that contacts the seat belt 20 has a certain curvature. In this way, the belt 20 is not worn by contact with a sharp edge during the process of abutting and tightening the belt 20, and the service life of the belt 20 can be prolonged.

As shown in fig. 6 and 7, at least one limiting hole 3213 is formed on a side of the sliding groove 3212 away from the rotating seat 322. When the webbing adjuster 30 is shifted from the closed state to the open state, the pusher 31 drives the pushing shaft 301 to move along the end of the sliding groove 3212 that is closer to the first rotating shaft 302 to the end that is farther from the first rotating shaft 302. Under the pressure of the webbing 20, the push shaft 301 is caught in the stopper hole 3213.

In this embodiment, the sliding groove 3212 is provided with four limiting holes 3213, that is, the adjusting assembly 32 has four gears. When the pushing shaft 301 is locked into a limiting hole 3213 farthest from the first rotating shaft 302, the service stroke of the safety belt 20 is shortest. The pusher 31 is set by default to move toward one of the stopper holes 3213 farthest from the first rotation shaft 302. During the movement, the push shaft 301 may be engaged in the limiting hole 3213 relatively close to the first rotating shaft 302 in advance due to different degrees of loosening of the seat belt 20 under different actual conditions and different pressures under emergency conditions.

According to one embodiment of the utility model, a speed sensor is provided in the safety seat that monitors changes in vehicle speed. After the child sits, the pressure switch 12 triggers the harness adjuster 30 to energize. When an emergency situation is encountered, the speed sensor detects a rapid change in speed signal and the seat belt regulator 30 opens before the seat belt 20 is subjected to force. The pusher 31 drives the pushing shaft 301 to lock into the corresponding limiting hole 3213, so that the adjusting assembly 32 is adjusted to be in an open state. The rotating seat 322 abuts against and tightens the safety belt 20, shortens the use stroke of the safety belt 20, and enables the child to be instantly fixed on the safety seat.

After returning from the emergency condition to the normal condition, the speed sensor detects a signal that the speed is stable. The pusher 31 adjusts the adjustment assembly 32 from the open state to the closed state, thereby resetting the seat belt adjuster 30 and restoring the use stroke of the seat belt 20. In this way, the webbing adjuster 30 can be reused.

In another embodiment, the safety seat is provided with a signal receiving tip that is connected to a forward collision prediction system of the vehicle. When an emergency situation is encountered, the signal receiving end receives a signal of rapid change in speed, the seat belt regulator 30 opens before the seat belt 20 is stressed. The pusher 31 drives the pushing shaft 301 to lock into the corresponding limiting hole 3213, so that the adjusting assembly 32 is adjusted to be in an open state. The rotating seat 322 abuts against and tightens the safety belt 20, shortens the use stroke of the safety belt 20, and enables the child to be instantly fixed on the safety seat.

After the emergency returns to the normal condition, the signal receiving end receives the signal with stable speed. The pusher 31 adjusts the adjustment assembly 32 from the open state to the closed state, thereby resetting the seat belt adjuster 30 and restoring the use stroke of the seat belt 20. In this way, the webbing adjuster 30 can be reused.

It will be appreciated that the seat belt adjuster 30 of the present utility model may be a relatively independent component that is removably mounted to the seat body 10 or may be directly secured to the seat body 10 as part of the seat body 10.

As shown in fig. 1, the safety seat of the present utility model further includes a headrest 40 and a seat base 50. The headrest 40 is disposed on the seat body 10 to provide support and protection for the child's head. The seat base 50 is provided with support legs 51 and ISOFIX interfaces 52. The support legs 51 support the safety seat and the ISOFIX interface 52 connects the child seat to the vehicle.

The safety seat of the utility model supports the safety belt 20 by arranging the safety belt adjuster 30 in an emergency situation to shorten the use stroke of the safety belt 20, so that the child is instantly fixed on the seat, thereby reducing the impact on the child and further improving the safety of the safety seat.

The present utility model is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any person skilled in the art can make some changes or modifications to the above-mentioned embodiments without departing from the scope of the present utility model.
