Abstract
The utility model proposes a kind of sofa backrest structure, the sofa backrest structure that the utility model provides, sofa backrest body top is provided with groove, filling sponge layer in groove, sofa backrest structure groove is arranged without backrest material of main part, only filling sponge layer, and uses elastic layer to fix spongy layer, make head rest the head on the more comfortable softness that gets on, also save backrest material of main part simultaneously.This sofa backrest structure is simple, and technique is simple, and when groove design makes to sleep soundly, head is fixing does not slide, and reaches the advantage of soft comfortable, protection neck, can also reduce production cost simultaneously.
Description
Technical field
The utility model relates to sofa field, particularly a kind of sofa backrest structure.
Background technology
The sofa backrest structure of prior art, in order to comfort level, is generally all provided with head rest at backrest structure body top, or, in order to reach comfort level, there is the sofa backrest structure that some sofa specialized designs are S-type.But these sofa backrest structures exist following problem: the material of the particularly softs such as the inner filling sponge of (1) head rest, cost is higher; (2) backrest structure material of main part is very hard, very uncomfortable above head leans against; (3) when people sleep soundly, be not easy when head leans against above to fix, easily cause neck to sprain; (4) technology difficulty is comparatively large, and process costs is higher.
Utility model content
Mirror is with this, and the purpose of this utility model is to provide a kind of sofa backrest structure, and structure is simple, and technique is simple, has the advantage of the not easily landing of soft comfortable, head, protection neck, can also reduce production cost simultaneously, solve the problems referred to above.
The technical solution of the utility model is achieved in that
A kind of sofa backrest structure, comprises backrest main body, is positioned at the groove of backrest body top and is filled in the spongy layer of groove.
Further, on described groove, horizontally set is used for the elastic of fixing spongy layer.
Further, described groove is rectangular recess.
Further, described groove is arc groove.
Further, the cross section of described arc groove is semicircular structure.
Further, described rectangular recess or described arc groove are provided with wavy bulge.
Compared with prior art, the beneficial effects of the utility model are:
The sofa backrest structure that the utility model provides, sofa backrest body top is provided with groove, filling sponge layer in groove, sofa backrest structure groove is arranged without backrest material of main part, only filling sponge layer, and use elastic layer to fix spongy layer, make head rest the head on the more comfortable softness that gets on, also save backrest material of main part simultaneously.This sofa backrest structure is simple, and technique is simple, and when groove design makes to sleep soundly, head is fixing does not slide, and reaches the advantage of soft comfortable, protection neck, can also reduce production cost simultaneously.
