Description

ISOFIX Interface Structure of Car Seats

technical field

The invention belongs to the technical field of car seat parts, in particular to an ISOFIX interface structure of a car seat.

Background technique

The ISOFIX (International Standards Organization FIX) interface is a child safety seat fixing interface accepted by many car manufacturers and countries. With the enhancement of people's safety awareness and the gradual popularization of laws and regulations, child safety seat interfaces have been generally designed on the car seats of cars and SUVs in my country. The ISOFIX interface is easy to install, rigid connection, and high safety. Therefore, most car manufacturers choose to adopt the ISOFIX interface.

The current situation is that there are two independent ISOFIX interfaces installed on each car seat. In order to meet people's comfort requirements for car seats, car seat cushions generally adopt an ergonomic curved surface design. Therefore, the seat cushion is generally also a curved surface structure at the installation place of the ISOFIX interface, resulting in the installation of the ISOFIX interface. When the force acting on the foam of the seat cushion is uneven, the foam and cover around the ISOFIX interface will often be crushed, causing wrinkles and gaps to appear around the ISOFIX interface, which not only affects the appearance of the car seat, but also easily hides dirt. dirt. In addition, due to the generally large tolerance of the seat frame, the ISOFIX interface is fixed on the seat frame, resulting in poor symmetry between the two ISOFIX interfaces on the same car seat, which makes the installation of the child safety seat difficult and often requires It takes two people to complete the installation. It is urgent to solve the above problems.

Contents of the invention

In order to solve the above technical problems, the present invention provides an ISOFIX interface structure of a car seat that will not collapse the seat foam, is clean and beautiful, and can ensure the consistency of the two ISOFIX interfaces on the same car seat.

To achieve the above object, the technical scheme of the present invention is as follows:

An ISOFIX interface structure of a car seat, the main points of which are: comprising a cover mounting base and two ISOFIX cover covers, the cover mounting base has two mounting holes penetrating front and rear, and the two ISOFIX cover covers They can be inserted into corresponding mounting holes respectively, and are detachably mounted on the cover mounting seat.

With the above structure, the cover mounting seat is fixedly installed on the seat frame first, and then the foam is foamed on the surface of the two together, so the cover mounting seat will not affect the external structure of the seat foam and the cover; through the cover mounting seat , so that the ISOFIX cover will only contact the installation hole of the cover mounting seat during installation and disassembly, and will not affect the surrounding seat foam and cover; through the above two points, wrinkles and gaps around the ISOFIX interface are avoided It not only makes the car seat more beautiful and enhances the high-level feeling of the car seat, but also does not hide dirt and is more clean and tidy; in addition, because the two ISOFIX covers are directly fixed on the cover mounting seat, the The relative settings of the two ISOFIX interfaces are unique and consistent, so that the installation of the child safety seat is convenient.

As a preference: the cover mounting seat has two forward protruding protrusions, and the two mounting holes are respectively located on the corresponding protrusions. With the above structure, when the ISOFIX cover is installed on the cover mounting seat, each protrusion and the installation hole can completely cover the ISOFIX cover. At this time, the protrusion is located between the seat foam and the ISOFIX cover. It further ensures that the ISOFIX cover will not act on the seat foam during loading and unloading, and more effectively prevents the problems of wrinkles and gaps caused by the collapse of the seat foam and the cover.

Preferably, the cover installation seat has a supporting connection part, and the two protrusions are respectively located at two ends of the supporting connecting part, and protrude forward from the supporting connecting part. With the above structure, the structure is reasonable, the support connection part is thin and the protruding part is thick, so that the cover mounting seat can be as small as possible and light as possible while ensuring its own structural strength, meeting the design requirements of lightweight vehicles.

As a preference: there is at least one observation hole on the cover mounting seat. The above structure is adopted to facilitate the observation of whether the connection between the cover mounting seat and the seat frame is reliable, and at the same time play a certain role in weight reduction to meet the design requirements for lightweight automotive components.

Preferably: the ISOFIX cover includes a panel portion and an embedded portion extending backward from the inside of the panel portion, the embedded portion is adapted to the mounting hole, and the front end of the mounting hole has a mounting platform adapted to the panel portion , when the ISOFIX cover is installed on the cover mount, the panel part is embedded in the installation sink, and the embedded part is inserted into the installation hole. With the above structure, the installation sink not only serves as a limit position, but also cooperates with the installation hole to make the ISOFIX cover more reliably supported on the cover mounting seat when it is in the installed state.

As a preference: the outer end of the embedded part has at least one snap joint, and the rear end of the installation hole has a bayonet socket adapted to the corresponding snap joint. By adopting the above structure, the ISOFIX cover can be detachably installed on the cover mounting seat, and the operation is convenient, the cost is low, the connection reliability is high, and the service life is long.

Preferably, the embedding part includes at least two supporting parts, both of which are elastic plate-shaped structures, and gaps are left between adjacent supporting parts. With the above structure, the structure is simple and reliable, and easy to realize, so that the ISOFIX cover can be detachably installed on the cover mounting seat.

As a preference: the middle part of the outer side of the panel part has an outwardly protruding reinforcing boss. The above structure further improves the structural strength of the ISOFIX cover and prolongs the service life of the ISOFIX cover.

As a preference: the inner side of the cover mounting seat has a ring of engaging structures distributed along its outer edge. By adopting the above structure, the reliability of the connection between the cover installation seat and the seat frame is further improved, and the installation is convenient and the operation is simple.

As a preference: the inner side of the cover installation seat has at least one support seat matched with the engaging structure. By adopting the above structure, the reliability of the connection between the cover mounting seat and the seat frame is further improved.

Compared with prior art, the beneficial effect of the present invention is:

The ISOFIX interface structure of the car seat provided by the present invention has a novel structure and is easy to realize. It can not only solve the problem of crushing the surrounding seat foam when the ISOFIX interface is installed, it is clean and beautiful, and can ensure two ISOFIX on the same car seat. The consistency of the interface facilitates the installation of the child safety seat and effectively improves the disassembly efficiency of the child safety seat.
