Abstract

The invention discloses an angle adjustable sleeper waist rest capable of being rapidly retracted. The angle adjustable sleeper waist rest comprises a back plate, a bottom plate hinged to the back plate, a drive mechanism and a rapid retracting mechanism, wherein the drive mechanism and the rapid retracting mechanism are arranged on the base plate. The drive mechanism is used for driving the back plate to rotate relative to the base plate. The rapid retracting mechanism acts on the drive mechanism to rapidly retract the back plate to an initial position. When a passenger rides on a sleeper provided with the waist rest, the inclination angle of the waist rest can be adjusted according to the comfort requirement of the passenger; and when the passenger needs to recover the waist rest, the waist rest can be rapidly retracted through the rapid retracting mechanism, and the angle adjustable sleeper waist rest is convenient, rapid and practical.

Description

technical field [0001] The invention relates to the field of vehicle and ship technology, in particular to a lumbar support for a motor vehicle sleeper. Background technique [0002] Sleeper berths are the berths for passengers to sleep on vehicles such as trains and ships. When passengers do not need to sleep during the day, sleeper berths have taken on the function of seats. With the development of science and technology and the improvement of people's living standards, people have higher requirements for the comfort of travel. The original sleeper pillow direction only had vertical walls, and passengers could not sit up comfortably to watch movies, read games and other entertainment activities. In the later period, a wall-mounted lumbar support also appeared, which reduced the discomfort when sitting up while lying down during the journey. Since the lumbar support is perpendicular to the wall, the experience for passengers is poor. [0003] The Chinese patent applicatio...
