Description

Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to a seat back support structure and an automotive seat. Background Technology

[0002] Car seats are increasingly focused on personalized design. In order to meet the various needs of customers, seat shapes are also evolving from simple to complex, such as adding core side panels around the core liner. However, the existing technology can no longer meet the needs of the current shapes. Especially for seats with core side panels, due to the limitations of the frame and foam, the upper rear part of the liner core cannot be fixed, causing the core side panels to be stretched and deformed (tilted), resulting in a poor shape effect. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, the present invention provides a seat back support structure. This support structure is integrated into the cover assembly. By cooperating with the frame, it can prevent the upper part of the side panel of the sewing assembly A from being deformed due to excessive backward pulling force. The design of the support structure can make the seat shape better and meet the existing styling requirements.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A seat back support structure includes a support piece, a limiting plate, a connecting piece, and a limiting piece. The limiting plate is located at the bottom of the support piece, contacts the seat frame assembly, and its end is close to the seat foam assembly. The side of the support piece near the sewing assembly A with the side panel sewn on it is connected to the limiting plate, forming a sewing assembly C. Both sides of the support piece with the limiting plate are connected to the front left and front right panels of the faceplate assembly, forming a sewing assembly D. The seam allowance formed at the connection point is located within the first accommodating groove of the frame assembly. The sewing assembly D is connected to the sewing assembly A.

[0006] The connecting piece has a hook hole at a position opposite to the claw of the skeleton assembly, and the limiting piece is located below the hook hole of the connecting piece; the supporting piece is connected to the sewing assembly B of the connecting piece and the faceplate assembly on the side away from the sewing assembly A with the side panel piece; the free-moving end of the connecting piece is hooked on the claw of the skeleton assembly, and the limiting piece is located in the gap between the claw and the skeleton assembly.

[0007] As a preferred embodiment of this utility model, the sewing assembly A is formed by sewing together a core piece and a side panel piece; the sewing assembly D is connected to the sewing assembly A, which has a side panel piece, by sewing to form the sewing assembly E.

[0008] As a preferred embodiment of this utility model, the sewing assembly B is formed by sewing together a rear left cut piece, a rear upper cut piece, a rear lower cut piece, and a rear right cut piece; the sewing assembly B is sewn together with the sewing assembly E to form the faceplate assembly.

[0009] This embodiment also provides a car seat, which includes a frame assembly, a foam assembly, and a faceplate assembly. The frame assembly has multiple claws hidden inside the frame assembly on its upper part, and a recessed first accommodating groove is provided on the upper part of the frame assembly near both sides. The foam assembly has a second accommodating groove at a position opposite to the accommodating groove of the frame assembly. The faceplate assembly has a support structure at a position opposite to the claws of the frame assembly.

[0010] Advantages and beneficial effects of this utility model:

[0011] (1) The support structure provided by this utility model is integrated on the face protection assembly. It works with the skeleton to prevent the upper part of the side panel on the sewing assembly A from being stretched and deformed due to excessive backward pulling force, thus affecting the shaping effect.

[0012] (2) The car seat provided by this utility model has a good styling effect. By adding a support structure to the protective surface, the protective surface is positioned and shaped. The protective surface, foam and frame support each other and form a stable and reliable connection, while ensuring the overall styling effect. This overcomes the problem that traditional design structures cannot meet the existing styling requirements. Attached Figure Description
