Split type structure of automobile backseat backrest framework and assembly method

Abstract

The invention discloses a split type structure of an automobile backseat backrest framework. According to the split type structure of the automobile backseat backrest framework, the obverse side of a right reinforcing plate of a backseat partition board is detachably connected with the lower right corner of the backseat backrest framework; the obverse side of a left reinforcing plate of the backseat partition board is detachably connected with the lower left corner of the backseat backrest framework; a rear floor of an automobile body is detachably connected with the middle section of the bottom of the backseat backrest framework; the lower portion of the reverse side of the right reinforcing plate of the backseat partition board is detachably connected with a right connecting plate of a rear wheel cover of the rear floor; the lower portion of the reverse side of the left reinforcing plate of the backseat partition board is detachably connected with a left connecting plate of the rear wheel cover of the rear floor; cross bars are arranged on the upper portion of the backseat backrest framework; the upper portion of the backseat backrest framework is connected with grooves in backrest hook supports through the cross bars; the upper portion of the reverse side of the right reinforcing plate of the backseat partition board is detachably connected with a right extension plate of a cross beam of a rear shelf; the upper portion of the reverse side of the left reinforcing plate of the backseat partition board is detachably connected with a left extension plate of the cross beam of the rear shelf. The split type structure expands the application range of the backseat partition board to various automobile types.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to a split structure and an assembly method of a rear seat back frame of an automobile. Background technique [0002] "GB15083-2006 Strength Requirements and Test Methods for Car Seats, Seat Fixtures and Headrests" is a national mandatory standard. During the collision, the moving luggage in the luggage compartment hits the back of the rear seat and caused injury to the occupants. This regulation not only focuses on the impact resistance of the seat structure itself, but also puts forward higher requirements on the fixing points of the seat and the body. For the weak design of the fixed point of the seat and the body, it is easy to cause the failure of the connection point when the moving luggage impacts, which leads to the failure of the car seat to meet the requirements of the national standard. [0003] The strength of the rear seat is determined by the strength o...

AI Technical Summary

Problems solved by technology

[0004] Since the backrest frame is integrated in the rear seat and cannot be disassembled, once the fixed point of the rear seat on the vehicle body changes due to vehicle modification or other reasons, the seat assembly will not be able to continue to be used, and a new seat needs to be developed

After the model is put into production, it is difficult to reduce the cost of the rear seat technology, and the actual benefits are very limited
