Description
Technical Field
The utility model relates to an auto-parts and assembly, concretely relates to car seat is by linkage 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:
firstly, the seat frame part of the back row seat can not be separated, and the seats on the two sides are still connected together, so that two completely independent parts can not be formed in the form;
secondly, because the armrests are embedded in the backrest, the length and the height of the armrests in the rear row are difficult to be considered simultaneously. Specifically, a, if the armrest is ensured to have enough length after being 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 being opened is very low, and the riding experience is seriously influenced; the existing solution is to increase the thickness of the handrail greatly for raising, but this will make the handrail too heavy; b. if the armrest is guaranteed to have enough height after being opened, the lower connecting point (hinged 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 described at 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.
SUMMERY OF THE UTILITY MODEL
