Problems solved by technology
[0002] At present, in the field of seat frames, most of them adopt the method of split control, and one operating handle can only control one part to achieve a single function.
For example, the reclining of the backrest or the forward and backward movement of the seat cushion can be realized through a single operating handle. The operation is complicated and the cost is high. Especially for the field of commercial vehicles, simple operation, strong functionality, convenience and high cost performance have become the focus of customer choice.

The invention discloses a linkage mechanism used for a seat. The linkage mechanism comprises a backrest component, an upper support component and a lower support component. The upper support componentis used for installing a seat cushion and driving the seat cushion to move, the upper support component and the lower support component are connected through sliding rails, and the upper support component can slide forwards and backwards relative to the lower support component. The bottom of the backrest component is rotationally connected with the upper support component, the middle part of thebackrest component is connected with the lower support component through a connecting board component, the end, connected with the backrest component, of the connecting board component can rotate relative to the backrest component, and the end, connected with the lower support component, of the connecting board component can rotate relative to the lower support component. The backrest component can be driven to move through front and back motion of the upper support component, the upper support component is used for installing the seat cushion, and therefore the function that the angle and theposition of the seat are adjusted through one key is achieved.
Description
technical field [0001] The invention relates to a linkage mechanism for a seat, which belongs to the technical field of vehicle accessories. Background technique [0002] At present, in the field of seat frames, most of them adopt the method of split control, and one operating handle can only control one component to achieve a single function. For example, the reclining of the backrest or the forward and backward movement of the seat cushion can be realized through a single operating handle, which is complicated and expensive to operate. Especially for the commercial vehicle field, simple operation, strong functionality, convenience and high cost performance have become the focus of customer choice. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a linkage mechanism for a seat to simultaneously control the seat cushion and the backrest. [0004] In order to solve th...
