With the increasing popularization of automobile traveling and the improvement of social living standard, passengers have higher requirements on comfort and functionality when the seat meets the basic riding requirement, particularly a passenger seat or a back row independent seat, and on the basis of meeting the basic seat adjusting function, the seat is expected to realize a lying posture state through mechanism adjustment, particularly a special position of zero gravity, so as to achieve the maximum comfort level.
The zero gravity position is that the legs, the buttocks and the back are driven in a linkage manner according to the principle of relaxing the space capsule, so that the heart and the knees are positioned on the same horizontal plane, the stress area of a human body is increased, and all parts of the body are uniformly stressed. In addition, the passengers are easy to get tired after taking for a long time, and if the seat can realize a lying posture for a short time rest, the requirement of the automobile seat on the comfort level can be better met.
The adjustment of the seat is generally divided into the adjustment of the front and back, height, backrest, waist, shoulder, leg support and the like of the seat. At present, the corresponding structure of the adjusting mechanism for realizing the lying posture of the seat raises the distance from the central line of a shaft of the seat, which is corresponding to the thigh and is connected with the trunk, to a lower slide rail which moves back and forth of the seat in order to realize the zero gravity function, or the internal structure is complex, thereby causing certain difficulty in the installation, the maintenance and the repair of the seat.
In view of the above, there is a need to provide a simple and effective overall seat adjustment mechanism to solve the described problems.
