The adjusting component can drive the upper support to rotate relative to the lower support. The safety belt is arranged in the seat backrest, so that the seat is more attractive and neat; the adjusting component is arranged on the upper bracket, so that a relatively wide space can be formed in the seat backrest for arranging the safety belt fixing seat, on one hand, the situation that the safety belt fixing bracket is arranged in the seat base to occupy the space of the seat base can be avoided, and the space in the seat backrest is effectively utilized; on the other hand, the length of the safety belt restraining groove can be reduced, the manufacturing cost is reduced, meanwhile, abrasion of the safety belt restraining groove to the safety belt can be reduced to a certain degree, and the service life of the safety belt is prolonged.

    本发明公开了一种座椅靠背骨架,其包括上支架、下支架、安全带固定支架、安全带约束槽和至少一个调节部件,上支架与下支架之间可转动连接,安全带固定支架设置在下支架上,安全带约束槽和调节部件分别设置在上支架上,调节部件能够驱动上支架相对于下支架转动。本申请将安全带内置于座椅靠背内,使座椅更加美观和整齐;通过将调节部件设置在上支架上,可以使得座椅靠背内部形成较为宽裕的空间设置安全带固定座,一方面可以避免安全带固定支架设置在座椅底座内占用座椅底座空间,有效利用座椅靠背内的空间;另一方面还可以减少安全带约束槽的长度,在降低制造成本的同时,还可以一定程度上降低安全带约束槽对安全带的磨损,延长安全带的使用寿命。
