Description

Car seat armrest mounting structure

Technical Field

The invention relates to an accessory and an assembly of an automobile seat, in particular to an automobile seat armrest mounting structure.

Background

The automobile seat framework is an internal key accessory for supporting the automobile seat, and the realization of many functions is realized by the design modification of the seat framework. The automobile seat frameworks are divided into front-row seat frameworks, middle-row seat frameworks and rear-row seat frameworks; of course, for automobiles with a greater number of occupants, the number and rows of seats will be greater. Generally, the functions and adjustment modes of the seat frame are as follows: the backrest framework driven by the angle adjuster rotates forwards and backwards, the seat frame framework moves forwards and backwards, and the height and elevation angle of the seat frame framework are adjusted. Based on the increasingly mature consumer market, the functional requirements of automobile seats are increasingly higher, and a host factory proposes to perform variable design on rear seats, so that the seats can meet the requirements of three persons for riding and can be changed into a two-person business mode. The existing design adopts a mode that a turnover handrail is directly arranged on a backrest, the lower part of the turnover handrail is hinged with the backrest, and when the turnover handrail is stored in the backrest, a three-person riding mode can be formed; when the armrests are turned over to be taken out of the backrest, the armrests divide the seats at two sides, so that a two-person business mode is formed. It has the following disadvantages:

(1) the seat frame parts of the back row seats cannot be separated, the seats at the two sides are still connected together, and the two completely independent parts cannot be formed in form;

(2) the length and the height of the back row armrests are difficult to be compatible because the armrests are embedded in the backrest. Specifically, if a, a sufficient length is ensured after the armrest is opened, the lower connecting point (hinge point) of the armrest needs to be closer to the seat frame, so that the height of the armrest after the armrest is opened is very low, and the riding experience is seriously affected; the current solution is to greatly increase the thickness of the handrail for heightening, but the handrail is too heavy; b. if the armrest is ensured to have enough height after being opened, the lower connecting point (hinge point) of the armrest needs to be lifted away from the seat frame, so that the length of the armrest after being opened is very short, and the riding experience is also influenced; or as indicated at a.

Therefore, the problem of the host factory needs to be re-reviewed and researched, and a seat frame with more comprehensive functionality and better experience is designed, especially for the rear seat frame.

In view of the above drawbacks, researchers need to consider at least the following problems:

1. how to realize the adjustment of the seat frame of the back row seat in a recoverable way between three positions and two positions;

2. when the three-position is changed to the two-position, the seat frame at one position which is subtracted should be placed, contained or hidden;

3. in the original design, whether the position and the arrangement mode of the armrests can be continuously used or not.

4. How to ensure that the back row armrests have enough length after being opened and enough height, and the thickness of the armrests cannot be increased.
