[0007] Working principle:
[0008] When using a recliner, the user needs to have a larger lying posture to make himself feel comfortable. First, the user gets up from the reclining board. At this time, the reclining chair is in a state where the user can lie down. Then, the operator separates the place where the support assembly is connected to the backrest. At this time, the backrest is gradually flush with the reclining board through the connection of the rotating shaft. At this time, the spring behind the backrest drives the steel coil to rotate, and the steel coil drives the slider to move in the slide groove, and the slider also drives the cushion to move at the same time. Through the movement of the steel coil, the steel coil can gradually pull the support assembly to be parallel to the reclining board. At this time, when the support assembly is flush with the reclining board, the operator supports and fixes the backrest near the head. In this way, the user can obtain a larger reclining area while lying on the reclining board and the backrest, and the user can also be more comfortable when using it.
[0009] The beneficial effects of the present invention are:
[0010] The provided support assembly can make the user more comfortable when lying on the recliner and reduce the possibility of tipping over during the lying process. After the user separates the support assembly from the backrest, the spring on the back drives the steel coil to move, and the steel coil drives the slider to move, and the slider drives the support assemblies on both sides of the reclining board to move until the support assembly is flush with the reclining board, so that the area for the user to lie flat on the reclining board is more spacious and the area for the user to lie flat is further expanded. The steel coil drives the slider, and the slider drives the cushion, so that when the reclining board is flush, the cushion is more concentrated in one area, so that the user's back is more comfortable when lying flat. The provided canvas can prevent the user's hair from touching the spring or steel coil when lying flat on the backrest, thereby preventing unnecessary accidents. BRIEF DESCRIPTION OF THE DRAWINGS
