Connection device for fixing child seat on international standards organization fix (ISOFIX) interface

Abstract

The invention relates to a connection device for fixing a child seat on an ISOFIX interface. The connection device comprises a U-shaped main body steel, wherein a sliding block, a pawl and pull rods are arranged between the main body steel, the sliding block is in an H shape and is arranged below the pawl, a cylindrical boss is arranged on the surface of the left end of the sliding block, pull rods are in a Z shape, left ends of two pull rods are welded together, the pawl is fixed on the main body steel through a pair of riveting shafts, two clamping grooves are arranged at the right end of the pawl, the left end of the pawl extends between two pull rods, two pull rods are connected with the pawl through sliding shaft holes, and a sliding shaft can slide inside a chute at the left end of the pawl. According to the connection device, functional holes which are used for installing switch indicators and switch pull rods are arranged at left ends of pull rods, and obvious indications are provided during opening or closing, so that losses caused by incorrect installation or improper installation by a user can be effectively avoided. The connection device has the advantages of being simple to operate, small in volume, high in strength and high in safety and is applicable to different series of child seats.

Description

technical field [0001] The invention relates to a device for fixing a child safety seat, in particular to a connection device for fixing the child seat on an ISOFIX interface. Background technique [0002] ISOFIX fixed child seats are secured to the vehicle by means of ISOFIX rigid connectors, known as ISOFIX connectors. ISOFIX seat fixing device is an international standard interface specifically for child safety seats, and its purpose is to standardize the installation and fixing devices of child safety seats. Usually, the child safety seat is combined with the car by means of two locks welded on the chassis. Through the ISOFIX system, the child safety seat can be integrated with the car, which can slow down with the car in advance instead of indirectly through the seat belt. It can reduce the impact on children, restrict children's body movement, and greatly improve children's safety. The movement and deformation of the "U" or "C" shaped steel brackets used in the prior...

AI Technical Summary

Problems solved by technology

The movement and deformation of the "U" or "C" shaped steel brackets used in the prior art are unpredictable during a collision, and may not be able to maintain the required load; when the seat belt is fixed, the tension of the seat belt If it is not high, it will cause the safety seat to shake; and there is no obvious locking indicator for the existing anchor device, and the user may install it incorrectly or improperly, causing certain losses
