AI Technical Summary

Technical Problem

The upper crossbeam frame of existing car seat backrests is prone to damage at the fixing point between the support plate and the upper crossbeam frame during long-term use.

Method used

Design a crossbeam frame structure for an automotive seat backrest, including a combination of a crossbeam frame, mounting base, mounting spring ribs, pressure base, and buffer springs. The mounting base and pressure base are slidably connected, and the buffer springs provide cushioning to reduce long-term stress damage. The installation stability is improved by the fixing structure of the limiting plate and mounting pins.

Benefits of technology

This effectively reduces damage at the fixing points between the support plate and the upper crossbeam frame, improving installation stability and service life.

Abstract

The utility model discloses an upper cross beam skeleton structure of an automobile seat backrest, which comprises a cross beam frame and a backrest plate mounted on the inner side of the cross beam frame, a mounting seat is arranged on the inner wall of the cross beam frame, a mounting spring rib is arranged on the inner side of the mounting seat, one end of the mounting spring rib penetrates through the mounting seat and is fixedly provided with a pressing seat, and the other end of the mounting spring rib is fixedly provided with a pressing plate. The pressing base is installed in the cross beam frame in a sliding mode, a buffer spring is arranged on one side of the pressing base, and the buffer spring is supported on the installation base. Holes are formed in the surface of the backrest plate, and the mounting spring ribs penetrate through the holes in the surface of the backrest plate; the pressing seat is in a T shape; through the designed mounting seat, during use, the mounting spring ribs are connected through the mounting seat and the pressing seat in the cross beam frame, the buffer springs are supported on the pressing seat, and during use, the backrest plate and the mounting spring ribs are stressed to drive the pressing seat to press the buffer springs for buffering, so that the phenomenon that the backrest plate is damaged due to long-term stress is reduced.
