Description

Car seat handrail mounting structure

Technical Field

The utility model relates to a car seat's accessory and assembly, concretely relates to car seat handrail mounting structure.

Background

The automobile seat framework is an internal key accessory for supporting the automobile seat, and the realization of a plurality of functions is completed through the design and modification of the seat framework. The automobile seat framework is divided into a front row seat framework, a middle row seat framework and a rear row seat framework; of course, for vehicles with a greater number of occupants, the number and rows of seats will also be greater. Generally, the functions and adjustment methods of the seat frame include: the backrest framework driven by the angle adjuster rotates forwards and backwards, the seat frame framework moves forwards and backwards, and the height and the elevation angle of the seat frame framework are adjusted. Based on the more and more mature consumer market, the functional demand of car seat is higher and higher, has proposed by the host computer factory, carries out variable design with back row seat, makes it can satisfy three people and take through the regulation, can change into two people's commercial models again. The existing design adopts a mode of directly arranging a turnover armrest on a backrest, the lower part of the turnover armrest is hinged with the backrest, and when the turnover armrest is stored in the backrest, a three-person riding mode can be formed; when the armrests are turned over and come out of the backrest, the armrests divide the seats on the two sides to form a two-person business model. It has the following disadvantages:

①, the seat frame part of the back row seat can not be separated, the two side seats are still connected together, the form can not form two completely independent parts;

②, because the armrest is embedded in the backrest, the length and height of the back armrest are difficult to be considered, specifically, a, if the armrest is long enough after being opened, the lower connection point (hinge point) of the armrest needs to be closer to the seat frame, which makes the height of the armrest after being opened very low, which seriously affects the riding experience, the current solution is to increase the thickness of the armrest greatly to be padded, which makes the armrest too heavy, b, if the armrest is high enough after being opened, the lower connection point (hinge point) of the armrest needs to be raised far away from the seat frame, which makes the length of the armrest after being opened very short, which also affects the riding experience, or as the point a.

Therefore, the problems proposed by the host factory need to be reviewed and researched to design a seat frame with more comprehensive functionality and better experience, particularly for the rear row.

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

1. how to realize the seat frame of the back row seat to carry out the recoverable adjustment between the three-person position and the two-person position;

2. when the three-person position is changed to the two-person position, how to place, store or hide the seat frame at the position of the subtracted seat frame;

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

4. How to ensure that the back row handrail has enough length and enough height after being opened and cannot increase the thickness of the handrail.
