The invention provides an integrated manual front-and-back adjusting mechanism for a seat headrest. The integrated manual front-and-back adjusting mechanism comprises a holder, a rotating support and a housing. The holder is connected to the headrest rod and provided with a through groove, and a plurality of gear grooves are formed in the inner wall of the through groove in the circumferential direction. The rotating support comprises a shaft body, the shaft body is rotatably connected to the through groove, the shaft body is provided with a convex rib, and the convex rib abuts against one gear groove in a limiting mode. The housing wraps the retainer and is connected with a rotary driving column, the rotary driving column is inserted into the through groove, a first elastic component is arranged between the housing and the rotary support, and a second elastic component is arranged between the housing and the retainer. When the housing is pushed, the rotary driving column moves along the through groove so as to drive the rotary support to move along the through groove firstly, and when the rotary support is separated from the current gear groove, the rotary support is driven to rotate until the convex rib is limited to abut against the other gear groove. According to the adjusting mechanism, a side unlocking button does not need to be arranged, the front gear and the rear gear can be adjusted only by pushing the headrest, operation is easy, and use experience is good.

    本发明提供一种集成式座椅头枕手动前后调节机构,包括保持架、转动支架和罩壳。保持架连接于头枕杆,保持架具有通槽,通槽的内壁沿周向设置多个档位槽。转动支架包括轴体,轴体可转动地连接于通槽,轴体设置有凸筋,凸筋限位抵顶于一档位槽上。罩壳包覆于保持架外部,罩壳连接有旋转驱动柱,旋转驱动柱插入于通槽内,罩壳和转动支架之间设置第一弹性部件,罩壳和保持架之间设置第二弹性部件。在推动罩壳时,旋转驱动柱沿通槽移动,以驱动转动支架先沿通槽移动并在转动支架脱离当前档位槽时,驱动转动支架旋转至凸筋限位抵顶于另一档位槽。本申请的调节机构不需要设置侧面解锁按钮,只需要推动头枕即可调节前后档位,操作简单,使用体验好。
