The invention relates to a seat depth mechanism with a seat basin adjusting function, which comprises a seat basin and a seat depth extension frame, the seat basin is slidably connected to a seat cushion supporting side plate, the seat depth extension frame is slidably connected to the seat basin through a seat depth slide rail, and a front transverse pipe driving mechanism for driving the seat basin and the seat depth extension frame is arranged at the front end of the seat cushion supporting side plate. The front transverse pipe driving mechanism comprises a transverse pipe, a base, a lead screw, a driving gear, a seat depth driving motor, a seat basin follow-up rack and a seat depth driving rack, the seat depth driving motor drives the seat basin to move back and forth through the lead screw, the seat basin follow-up rack on the seat basin drives a small gear of the driving gear to rotate, and a large gear synchronously rotating with the small gear drives the seat depth driving rack; the seat depth driving rack drives the seat depth extending frame to slide on the seat basin; the seat cushion has the advantages that the whole seat basin of the seat cushion moves forwards to increase the seat depth, meanwhile, the seat basin can drive the seat depth support to move forwards in a doubled mode, the seat depth adjusting stroke of the seat cushion is greatly increased, and various sitting posture requirements are met.

    本发明涉及一种带有座盆调节功能的座深机构,包括:座盆、座深延伸架,座盆滑动连接在座垫支撑侧板上,座深延伸架通过座深滑轨滑动连接在座盆上,座垫支撑侧板前端设置有驱动座盆及座深延伸架的前横管驱动机构,前横管驱动机构包括:横管、底座、丝杠、驱动齿轮、座深驱动电机、座盆随动齿条和座深驱动齿条,座深驱动电机通过丝杠带动座盆前后运动,座盆上的座盆随动齿条带动驱动齿轮的小齿轮转动,与小齿轮同步转动的大齿轮带动座深驱动齿条,座深驱动齿条带动座深延伸架在座盆上滑动;本发明的优点:座垫整个座盆向前运动增加座深,同时座盆还能驱动座深支架加倍向前运动,大大增加座垫座深调节行程,以适应各种坐姿需求。
