Description
Technical field
The present invention relates to automobile seat accessories, and in particular to a kind of automobile seat accessories.
Background technique
Chair framework lightweight has become the design requirement of most of main engine plants, in order to realize lightweight, material replacement and
Structure design be frequently with two ways.Specifically, select the higher steel sheet metal component of intensity can reduce its dosage to
Weight is reduced, aluminium alloy, magnesium alloy can also be used as alternative materials；And use the universal thinking of structure design reduction weight are as follows:
Repeated hole is reduced, does hollow structure, but when carrying out the light-weight design of structure, it is also necessary to the machinery that must reach in view of structure
Intensity has balanced the relationship between lightweight and intensity；Existing structure design has been difficult further to reduce weight.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of seat back-rest framework.
Technical solution is as follows:
