Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to an automobile seat structure with an ISOFIX fixing point structure. Background Art

[0002] The ISOFIX interface is a child safety seat fixing interface accepted by many automobile manufacturers and countries. With the enhancement of people's safety awareness and the gradual popularization of laws and regulations, my country has generally designed child safety seat interfaces on car seats of cars and SUVs.

[0003] In the prior art, a Chinese patent with publication number "CN218054947U" discloses a car seat, which is provided with a fixing rod and a rotating rod to rotate the pillow downward so that the pillow can support the neck, reduce the neck pain after long-term driving, and thus improve the comfort of using the seat. A fixing plate is provided to limit the rotating rod from continuing to rotate in the direction away from the seat, so that the pillow is fixed above the seat back, so that it is convenient to use the pillow to support the head. A positioning hole is provided to allow the locking rod to slide through the connecting plate and the positioning hole to limit the sliding state of the rotating rod, so that the rotating rod and the fixing rod are hinged, and then the pillow is fixed at a suitable height, so that it is convenient to adjust the height of the pillow, and solves the problem of the existing car seat structure that when the driver sits on the driving seat, the pillow supports the head, but the driver's neck is in a suspended state. After driving for a long time, symptoms such as neck pain will occur, thereby reducing the comfort of using the seat.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] Nowadays, when people sit in car seats, their backs rest on the backrest of the car seat, which causes their waists to be suspended. After driving for a long time, it will affect lumbar spine diseases. Although people can buy a lumbar pad and put it on the car seat, if the lumbar pad is lost, it cannot arrive in time, which will cause people to not be protected by the health protection of the lumbar pad for a period of time. In addition, there will be an ISOFIX interface on the car seat for installing child seats, but the child seat is fixed to the car seat through the ISOFIX interface. When the vehicle shakes, this will greatly increase the bearing capacity of the ISOFIX interface, and will affect the service life of the ISOFIX interface over a long period of time.
