Description

Automobile seat framework with linkage of back row seat Technical Field The utility model belongs to the technical field of automobile seats, and particularly relates to an automobile seat framework with linkage of back row seats. Background The automobile seat is taken as an important part on an automobile, provides a safe and comfortable riding position for passengers, but with the continuous improvement of the comfort requirement of customers on the automobile, the requirement of vast customers cannot be met because only front and middle-row seats can be adjusted and unfolded backwards, and an automobile seat framework with adjustable and unfolded rear rows and even large angles is urgently needed. The back row seat backrest can only be turned forwards but cannot be adjusted backwards at present due to the limitation of the vehicle body structure and space, and if the back row seat backrest is to be adjusted backwards, the backrest is required to be driven to tilt and rotate by the forward movement of the seat cushion, and the back row seat cushion in the prior art cannot basically move forwards and backwards and cannot drive the backrest to tilt and rotate. Therefore, it is necessary to design a seat frame structure which has a simple structure and can realize the backward tilting of the back row backrest. Disclosure of utility model The utility model provides a rear-row seat-backrest linkage automobile seat framework, and aims to solve the problems set forth in the background art. The utility model is realized in such a way that the automobile seat framework with the linkage of the back row seat and the backrest comprises a sliding rail component, a cushion framework, a backrest framework, a connecting rod and a connecting plate; The sliding rail assembly is arranged at the lower end of the cushion framework and used for driving the cushion framework to slide back and forth, the upper end of the cushion framework is connected with the backrest framework, the upper end of the backrest framework is connected with the connecting plate through the connecting rod, and the connecting plate is fixedly arranged on the vehicle body frame. Preferably, the sliding rail assembly comprises a sliding rail and a sliding block, the sliding block is in sliding connection with the sliding rail, and the cushion framework is fixedly connected with the sliding block. Preferably, the cushion skeleton is rotatably connected with the backrest skeleton. Preferably, one end of the connecting rod is rotatably connected with the backrest framework, and the other end of the connecting rod is rotatably connected with the connecting plate. Preferably, when the seat needs to be adjusted, the sliding block in the sliding rail assembly drives the cushion framework to slide forwards in the sliding rail, at the moment, the lower end of the backrest framework is driven to synchronously move forwards, meanwhile, the upper end of the backrest framework is driven by the connecting plate to be incapable of moving forwards, the upper end of the backrest framework moves downwards through the connecting rod, and at the moment, the inclination angle of the backrest is increased. Preferably, the method comprises the steps of, Compared with the prior art, the utility model has the beneficial effects that: 1. The seat backrest linkage rear seat framework is characterized in that the seat backrest is rotatably connected through the seat cushion backrest, and the backrest is fixed on the vehicle body through the connecting rod; 2. By adopting the back-row seat framework with the linkage of the sitting and leaning, the backrest is fixed on the vehicle body through the connecting rod and the connecting plate, so that the sitting and leaning can be adjusted to a larger angle; 3. By adopting the back-row seat framework with the linkage of the seat and the backrest, the upper end and the lower end of the backrest framework are fixed to a certain extent, so that the strength of the seat is required to be the strength of a conventional seat in the current market.
