Car seat back skeleton
A car seat and frame technology, applied in the direction of the seat frame, etc., can solve the problems that the static strength and collision strength of the seat cannot be achieved, the manufacturing tolerance of the back frame assembly is large, and the energy absorption of plastic materials is poor, so as to reduce the special equipment and the cost of process equipment, shortening the production cycle, and reducing the weight

[0029] See Figure 3-12 , The car seat back frame 2 of the present invention replaces the original product formed by a combination of multiple metal parts with a plastic product formed by one injection or injection molding. It greatly optimizes the processing technology of the original metal frame, and breaks through the constraints of the original metal frame, allowing the entire seat to have a better appearance and comfort performance under the platform of the plastic seat frame.
[0030] The backrest frame 2 of the present invention uses plastic materials. The density of the seat back of plastic materials is usually much lower than that of metal materials. Plastics replace metal, which greatly reduces the weight of the seat back frame. The new product of the present invention has flexible material selection, and all materials whose strength and toughness can make the skeleton meet the requirements of regulations can be selected, such as PA66+GF or PP+GF. The weight of an ordin...
