Technical Field
The invention relates to the technical field of automobile seats, in particular to a motor-driven connecting rod type cushion folding mechanism.
Background
With the development of mobile office and leisure culture, the requirements of people on vehicles are not only satisfied with walking tools, but gradually develop towards the direction of household and office movable spaces. In order to meet the switching requirements of people in different scenes such as meeting, leisure, resting and the like in a vehicle, requirements on the functionality and changeability of the seat are provided, and the storage seat is derived from the requirements.
The folding mechanism of the traditional car rear seat usually folds the backrest of the rear seat forward, so that the front surface of the backrest is closely attached to the front surface of the cushion and is horizontally arranged, thereby increasing the available space above the seat. However, for some vehicle types in which the positions of the stowable seats are used as the passages, the folding mechanism cannot meet the requirements, and because the rear seats occupy too much space in the vehicle when stowed, the backrest adjustment of the front seats is also limited, which seriously affects the comfort of the front passengers, so the cushion folding mechanism gradually appears in the market at present. The cushion turnover mechanism is that the backrest is fixed and the cushion is turned over, so that a space at the position of the cushion before turnover is reserved. However, most of the existing cushion folding mechanisms are directly turned at the bottom end of the backrest, and under the influence of the backrest, the cushion can only be turned at a certain angle, and cannot be turned at a large angle of 90 degrees or more than 90 degrees, and the space occupied by the folded cushion is still large.
