Description

Seat back support type structure and automobile seat Technical Field The utility model belongs to the field of automobile seats, and particularly relates to a seat back support type structure and an automobile seat. Background In order to meet various demands of customers, the automobile seat is increasingly focused on personalized design, the seat modeling is also developed from simple modeling to complex, for example, the core side periphery is increased on the periphery of the core protection surface, but the prior art cannot meet the demands of the existing modeling, especially for the seat provided with the core side periphery modeling, the back upper periphery of the protection surface core cannot be fixed due to the limitation of a framework and foam, so that the core side periphery is pulled and deformed (inclined), and the modeling effect is poor. Disclosure of Invention In view of the defects and shortcomings of the prior art, the utility model provides a seat back support type structure, which is integrated on a facing assembly, and can avoid the situation that the upper periphery of a side surrounding cut piece on a sewing assembly A is pulled and deformed due to overlarge backward tension by being matched with a framework, and the design of the support type structure can enable the seat to be better in shape and meet the existing shape requirements. In order to achieve the above purpose, the utility model adopts the following technical scheme: The seat backrest supporting structure comprises a supporting cut-off piece, a limiting plate, a connecting cut-off piece and a limiting cut-off piece, wherein the limiting plate is arranged at the bottom of the supporting cut-off piece, is in contact with a framework assembly of a seat, and is close to a foam assembly of the seat at the end part, one side of the supporting cut-off piece, which is close to a sewing assembly A with side surrounding cut-off pieces, is connected with the limiting plate to form a sewing assembly C; The connecting cut pieces are provided with hanging holes at positions opposite to the clamping claws of the framework assembly, the limiting cut pieces are arranged below the hanging holes of the connecting cut pieces, one side, away from the sewing assembly A, provided with the side surrounding cut pieces, of the supporting cut pieces is connected with the connecting cut pieces and the sewing assembly B of the facing assembly, the free ends of the connecting cut pieces are hung on the clamping claws of the framework assembly, and the limiting cut pieces are arranged in gaps between the clamping claws and the framework assembly. The sewing assembly A is formed by sewing the core cut pieces and the side surrounding cut pieces in a sewing mode, and the sewing assembly D is connected with the sewing assembly A provided with the side surrounding cut pieces in a sewing mode to form a sewing assembly E. As the preferable mode of the utility model, the sewing assembly B is formed by sewing a rear left cutting piece, a rear upper cutting piece, a rear lower cutting piece and a rear right cutting piece in a sewing mode, and the sewing assembly B and the sewing assembly E are sewn together to form the facing assembly. The embodiment also provides an automobile seat, which comprises a framework assembly, a foam assembly and a facing assembly, wherein a plurality of clamping claws hidden in the framework assembly are arranged above the framework assembly, first concave containing slots are formed in positions, close to two sides, of the upper side of the framework assembly, second containing slots are formed in positions, opposite to the containing slots of the framework assembly, of the foam assembly, and a supporting structure is arranged in positions, opposite to the clamping claws of the framework assembly, of the facing assembly. The utility model has the advantages and beneficial effects that: (1) The support structure provided by the utility model is integrated on the facing assembly and matched with the framework, so that the upper periphery of the side surrounding cut-off piece on the sewing assembly A can be prevented from being pulled and deformed due to overlarge backward tension, and the modeling effect is prevented from being influenced. (2) The automobile seat provided by the utility model has good modeling effect, the facing is positioned and shaped by adding the supporting structure on the facing, and the facing, the foam and the framework are mutually supported and matched to form stable and reliable connection, meanwhile, the whole modeling effect is ensured, and the problem that the traditional design structure cannot meet the existing modeling requirement is solved.
