Adjustable sleeper

Abstract

The invention discloses an adjustable sleeping berth which comprises a sleeping berth underframe and a sleeping berth cushion. A set of sleeping berth leg supporting mechanisms are arranged on the sleeping berth underframe under the sleeping berth cushion where the thighs and lower legs of a passenger are placed; and the sleeping berth leg supporting mechanisms are in driving connection with a set of sleeping berth leg supporting elevation drive devices. The adjustable sleeping berth is flat in an initial state; during the running of a train, the sleeping berth leg supporting mechanisms on the knee part of the sleeping berth can be raised or lowered manually so as to obtain a satisfying and comfortable W curve according to the demands of the passenger. The maximal raising value can reach 80mm.

Description

technical field [0001] The invention relates to a design of a berth for a passenger car, in particular to an adjustable sleeper berth for a passenger car. Background technique [0002] With the development of China's economy and the development of transportation industry, people's travel is more convenient and frequent. China has a vast territory and abundant resources, with a large span from east to west, north to south, and places that cannot be reached by railways. The transportation capacity across provinces and regions still requires road buses, and sleeper buses are the passenger car products developed today to solve long-distance passenger transportation. The birth of sleeper buses is to comply with the market. It solves the comfort problem of long-distance changing from a sitting position to a lying position. However, in today's market economy, in order to increase economic benefits, sleeper buses and sleeper products can be designed with as many sleepers as possibl...

Problems solved by technology

However, in today's market economy, in order to increase economic benefits, sleeper buses and sleeper products can be designed with as many sleepers as possible under the premise of meeting national standards. At the same time, the bedding height cannot be designed according to the ideal curve. Because the height of bunk beds is also restricted by national standards

This can only be achieved by reducing the effective length of the sleeper, increasing the inclination angle of the upper end of the sleeper, or reducing the thickness of the sponge on the feet. Using this method will cause the entire sleeper to become a downward angle, and with the forward inertia of the car body and vibration, passengers’ bodies will slide unconsciously without support, which will eventually affect the overall comfort of the sleeper

However, with the improvement of people's living standards, people's travel requirements for rides are getting higher and higher, and the discomfort of sleeping berths will lead to a decline in the ride rate, which directly affects economic benefits.
