Embodiment 1

[0037] A backrest structure of an adjustable seat depth seat, such as Figure 1-11 As shown, it includes a keel support 200 extending downward from the seat vertical axis 100 and a backrest portion 300 located at the end of the keel support 200 away from the seat vertical axis 100 and extending approximately along the back of the human body. The backrest structure can be applied to any seat with a seat vertical axis 100 , and is suitable for a seat that supports the entire back cushion through a single seat vertical axis 100 . The end of the keel bracket 200 is slightly enlarged, and the end is connected with the backrest part 300 through a connecting piece.

[0038] The end of the keel bracket 200 connected to the backrest portion 300 extends downward while extending to both sides of the seat. Viewed from the front, the keel bracket 200 extends toward both sides of the seat vertical axis 100 except for the sleeve portion 400 connected to the seat vertical axis 100 .

Abstract

The invention relates to a part of a movable seat and discloses a backrest structure of a seat with an adjustable seat depth. The backrest structure comprises a keel bracket which extends downwards from the axial direction of a vertical shaft of the seat, and a backrest part which is located at the tail end, far away from the vertical shaft of the seat, of the keel bracket and roughly extends along the back of a human body, wherein the tail end, connected with the backrest part, of the keel bracket extends downwards while extending towards the two sides of the seat. The backrest structure has the advantages that the backrest part has enough elasticity, and can be relatively perfectly fitted with the back part of the human body; the keel bracket with the special design has enough strength and can support relatively heavy weight, so that the whole structure strength of the seat is improved; and meanwhile, the backrest part of the seat can more easily move along the vertical shaft of the seat.

Description

technical field [0001] The invention relates to a component of a movable seat, in particular to a backrest structure of a seat with adjustable seat depth, which can be used as a learning seat for children. Background technique [0002] The adjustable seat depth seat is a kind of seat that is mostly used in office places. It is known that the seat depth can be adjusted and the backrest fits the back of the human body. But existing seat back structure can't be suitable for the people of different builds well, for this reason, some seats adopt movable backrest structure, thereby realize the adjustment to backrest structure, these movable backrest structures have improved seat. The structural complexity of the seat increases the manufacturing cost of the seat, and at the same time reduces the structural strength of the entire seat to a certain extent. [0003] In view of this, it is necessary to develop a backrest structure with better strength and higher comfort. Contents of...
