technical field

The utility model belongs to the technical field of automotive supplies, and relates to an ISOFIX fixing device for a restraint system for child occupants of a motor vehicle, in particular to an ISOFIX shifting device for a stepless adjustable child restraint system.

Background technique

ECE R44/04 "Unified Regulations on Restraint Devices for Child Occupants of Motor Vehicles" and GB27887-2011 "Restraint Systems for Child Occupants of Motor Vehicles" stipulate that there are two ways to fix the child restraint system on the vehicle: one is to use on-vehicle The adult seat belt is fixed, and the other is fixed by the child restraint system ISOFIX fixing device. The ISOFIX fixing device makes the installation of the child restraint system simple, and can well reduce the wrong use rate of the child restraint system due to the use of adult seat belts to fix the child restraint system, effectively improving the safety of children in cars.

The ISOFIX shifting device is used to extend the ISOFIX guide bar from the structure of the child restraint system to an appropriate length to match the car seats of different models. Among the existing ISOFIX shifting devices, some are designed with several fixed shift positions, which cannot ensure that the child restraint system fits the car seat; although some can also achieve continuous adjustment, the adjustment is inconvenient, and the adjustment mechanism is prone to failure, such as CN101573252A. In addition, CN204978314U discloses an ISOFIX electric telescoping device for a car seat. Although it can be continuously adjusted, it requires a reliable forward and reverse motor to shift gears with electric control of ISOFIX, and the cost is high.

ISOFIX interface bracket, the ISOFIX interface bracket includes a main bracket body slidingly installed on the first groove frame and the second groove frame of the fixed bracket, and a rack connected with the main bracket body, the rack and the first groove frame Arranged in parallel with the second groove frame, an adjustment device, the adjustment device includes an adjustment handle, a shaft body and a gear, the shaft body is fixedly connected to the gear as a rotating shaft, at least one end of the shaft body is connected to the adjustment handle, and the rack is meshed with the gear , by adjusting the handle to drive the gear to rotate, and the rotation of the gear drives the rack to move back and forth along the setting direction of the first groove frame and the second groove frame, thereby causing the ISOFIX interface bracket to move forward and backward along the first groove frame and the second groove frame, realizing the replacement file; and a limit locking mechanism, which is used to limit and lock the adjusting device.

Further, the shaft body includes a square shaft body part between the first groove frame and the second groove frame body and a circular shaft body part outside it, and the limit locking mechanism includes a shift fork, so The first groove frame is provided with an inverted L-shaped groove at the installation place of the shaft body, and one end of the shift fork is provided with a fork-shaped body that can clamp the square shaft body. On the top of the inverted L-shaped slot, when the child restraint system is adjusted to a proper position, the shift fork is pulled down, and the fork-shaped body blocks the square shaft body to play a role of limit lock.

Further, the shaft body and the adjustment handle are integrally formed.

Further, the ISOFIX interface bracket also includes two parallel ISOFIX guide rods, an ISOFIX support rod vertically fixed between the two parallel ISOFIX guide rods, a first ISOFIX connecting frame vertically welded between the two parallel ISOFIX guide rods, parallel to For the second ISOFIX connecting frame of the first ISOFIX connecting frame, the rack is vertically welded between the first ISOFIX connecting frame and the second ISOFIX connecting frame.

Further, ISOFIX guide grooves are provided on the inner bottoms of the first groove frame and the second groove frame, and the second ISOFIX connecting frame can slide in the ISOFIX guide grooves.

The front end of the ISOFIX guide rod is provided with an ISOFIX interface, and the side close to the ISOFIX interface is provided with an ISOFIX release device.

By adopting the above-mentioned technical scheme, the utility model has the beneficial effects that: the utility model can provide a continuously adjustable, convenient and labor-saving, and not easy to fail the ISOFIX shifting device of the child restraint system, so that the child restraint system can further fit the car seat . The utility model has the advantages of simple structure, low cost, convenient use, safety and reliability.
