Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a multifunctional folding sofa chair. Background Art

[0002] At present, electric beds are widely used, including home electric beds and medical electric beds. Their main purpose is to facilitate the use of users. Electric beds mainly use electric control to automatically raise or lower the bed when the user needs it. Some electric beds are composed of multiple sections, and the up and down movement of the multiple sections is controlled by an electric control system, so that they can be folded to form a bed chair to facilitate the user's lying and sitting needs. However, most electric beds currently have the problem that when the user wants to sit, the user is likely to slip off the bed chair due to unreasonable electric control and / or structural design. This brings great inconvenience to the user, especially for patient users, and may cause secondary injuries. For this reason, a multifunctional folding sofa chair is proposed. Utility Model Content
