Description

Technical Field

[0001] The utility model relates to the technical field of heavy truck sleeper berths, in particular to a backrest lifting mechanism for a lower sleeper berth on a heavy truck. Background Art

[0002] The traditional lower berth of a heavy truck can usually only provide a bed for the driver or passenger to rest. Its structure is basically a layer of bottom plate with a sponge cushion on top. In recent years, some heavy truck models have added a rear seat on one side of the lower berth to meet regulatory requirements in the extended cab. The seat structure is very simple. Usually only a seat back is added to the wall at the rear end of the berth, and part of the berth is used as a seat cushion. The first type of traditional heavy truck lower berth is just a bed. Users can only choose to lie down when using it, and it has a single function. The second type of lower berth with integrated rear seats has a seat structure that is too simple and can only meet regulatory requirements. It does not have the function of a traditional seat for users to sit on. The backrest is vertical and the cushion is horizontal. The comfort and functionality are not improved compared to the first type. In order to solve this problem and improve the convenience of berth adjustment, this application provides a lifting mechanism for the backrest of the lower berth of a heavy truck. The following problems exist in the prior art:
