Background technique

At present, there are two types of vehicles used for medium and long-distance passenger transportation: seat passenger vehicles and sleeper passenger vehicles. The structure of the seat bus is generally the same, only different in grade, and the passenger's riding posture is a sitting posture. In order to improve the comfort of the ride, the angle of the backrest of the general seat can be adjusted, but due to the small space, the adjustment range is limited. If the passenger rides for a long time, it will cause fatigue all over the body.

Sleeper buses have two structures: adjustable semi-lying and flat. The former has poor comfort during sleep and is suitable for waking states; the latter is mainly designed for the long-distance passenger transport market, with the purpose of enabling passengers to lie flat and rest, thereby reducing fatigue. But there are also defects. Lying down is the best way for passengers to rest when they are in a more fatigued state, but when the passengers are not tired, lying there is uncomfortable. In fact, passengers spend most of their time in a non-sleeping state.

Judging from the above analysis, seat buses and sleeper buses have a common disadvantage, that is, they can only provide passengers with a way of rest, either sitting or lying down. Therefore, the current passenger car structure cannot fully meet the needs of long-distance passenger transport, and a new structure needs to be designed to improve the competitiveness of road passenger transport.

But seat car and sleeper car also all have its own advantages, sitting is the best way of rest when passengers ride for a short time, lying is the best way of rest when passengers are tired. If the advantages of both can be absorbed and their disadvantages avoided, and a seat that can be seated and reclined and can be arranged on a bus is designed, the ride comfort can be greatly improved. Sitting and lying dual-purpose functional seat seat occurs under the background of such technical requirements.
