Frame structure of full-flat air seat

Abstract

The invention discloses a frame structure of a full-flat air seat, which comprises a fixed frame component, a traction frame component, a bottom plate component, a backrest component and a first telescopic component; the traction frame component is slidably arranged in the fixed frame component; the bottom plate component is slidably arranged in the fixed frame component and hinged to the upper part of the traction frame component; the bottom of the backrest component is hinged above the rear end of a seat plate component; the upper end of a support rod component is hinged with the bottom of the rear end of the fixed frame component, the upper end of the support component is hinged with the bottom of the backrest component, and the hinge point between the support component and the backrestcomponent is positioned above the hinge point between the backrest component and the seat plate component; one end of the first telescopic component is fixedly arranged on the fixed frame component,and the other end of the first telescopic component is fixedly arranged on the traction frame component. The seat can realize the electric full-flat or resetting of the chair, has the advantages of simple structure and light weight, and can improve the overall reliability of the seat frame.

Description

technical field [0001] The invention belongs to the technical field of aviation seats, and in particular relates to a skeleton structure of a full-flat aviation seat. Background technique [0002] There are many electric full-flat aviation seats in foreign countries, and there are various seat frame structures, but most of the driving methods use a rotating motor to pull the rack to realize the seat lying flat, which leads to a complicated structure of the seat frame and is not conducive to Seat repair and reset. Domestically, there are also electric tilt-flat aviation seats, which are driven by linear motors, but they cannot fully lie flat and have relatively large traction. Contents of the invention [0003] The purpose of the present invention is to provide a fully flat aviation seat frame structure, which converts the linear motion of the linear motor into the reclining motion of the backrest assembly and the forward extension motion of the seat panel assembly, and fi...
