Problems solved by technology

[0002] At present, with the improvement of people's living standards, people have more and more requirements for the comfort of ordinary passenger seats, especially in long-distance passenger transport. The relative distance between the two rows of seats used on long-distance passenger transport vehicles is fixed. , and usually only the backrest can be adjusted back and forth. For passengers who ride for a long time, there is very limited space for adjusting the sitting posture. Long-term rides will cause physical fatigue to the passengers, long-term stress on the hips and lumbar spine, and pressure on the thighs , the blood flow is not smooth, resulting in problems such as swelling of the calf and feet, which cannot well meet the comfort requirements of passengers

Abstract

The invention relates to the technical field of seats, in particular to a novel backrest and seat frame linkage type seat. The seat comprises a fixed frame, a rotary frame, a seat frame, a backrest frame, an air spring and armrest frames. The backrest and the cushion are arranged to be a linkage mechanism, so the seat frame can move forwards and backwards while the back is supine, the sitting posture adjusting amplitude of a passenger is increased, the body of the passenger is stretched, the stress on the waist and buttocks is decomposed, the fatigue feeling of the passenger is effectively relieved, and the comfort is better. By arranging the rotating mechanism between the fixed frame and the rotating frame, the seat can be rotated by 180 degrees, the direction of the seat can be adjustedaccording to the running direction of a vehicle, and discomfort conditions such as carsickness of passengers can be effectively avoided. The built-in tea table is arranged between the armrest frame and the backrest protective cover, so the use and the operation are convenient, the external space is not occupied, the overall appearance attractiveness of the chair is good, the bad problems of tabletop damage, inclination and the like caused by long-time use of the tea table in the prior art are solved, and the service life is long.
