Description
Technical field
It the utility model is related to a kind of automobile seat accessories, and in particular to a kind of front-seat integrated backrest bone of automotive seat
Frame.
Background technology
Traditional car seat headrest is that split is fabricated with backrest, and head rest pole is set on headrest, head is set on backrest
Pillow pipe, is assembled by the cooperation of head rest pole and headrest tube.Split type headrest and backrest frames, the process of each self assembly are numerous
Trivial, process is more, is either formed by the welding of multiple parts or is processed by the mould of complexity.Time cost, original
Expect that cost and cost of labor are also of a relatively high；For the automotive seat for the regulatory function that need not rest the head on, split is fabricated
Headrest and backrest frames, which seem, to be not necessarily to.
It is connected between backrest side bar by crossbeam, for the comfortableness of seat occupants back, draws and be provided between two side bars
Serpentine spring.Traditional snake spring hangers is mostly single accessory, by subsequently assembling, is welded on side bar.So not only take
Arduously, and the welding quality of snake spring hangers can not completely be ensured.Later it has been proposed that being integrally formed snake spring on side bar
Hangers, but the structure of snake spring hangers is wordy in its scheme, is not easy to be stripped, and still only played the single of connection snake spring
Effect；Also, traditional backrest side bar, backrest serpentine spring is connected directly on side bar, due to vertical side bar and human body back
Face Area of bearing it is smaller, thus comfortableness is poor.
Utility model content
To solve one or more technical problems above, the utility model provides a kind of automotive seat front-seat integrated backrest
Skeleton.
Technical scheme is as follows：
