Provided is an anti-submarining device for a vehicle seat. The vehicle seat is provided with a front half seat pot, a back half seat pot and a cross beam tube, wherein the front half seat pot and the back half seat pot are connected in a pivoted mode, and the cross beam tube is fixed in the front of the front half seat pot. The anti-submarining device is arranged at any one end of the cross beam tube and includes: a lifting assembly, a control assembly, a cross beam tube end plate, a lifting arm and an actuating unit. The lifting assembly is connected with the cross beam tube to lift the cross beam tube. The control assembly controls the lifting assembly to move. The lifting assembly includes an impact arm remaining support fixed on the vehicle seat. The cross beam tube end plate is connected with the end of the cross beam tube and the impact arm remaining support in a pivoted mode. The lifting arm is connected with the cross beam tube in a pivoted mode. The actuating unit is connected with the lifting arm in a pivoted mode and is slidably and rotatably connected with the impact arm remaining support. The control assembly receives point initiation signals or pressure signals of an air bag to send control signals to the actuating unit, the actuating unit quickly actuates on the basis of the control signals to lift the cross beam tube and further to lift the front half seat pot at a certain angle. The invention further relates to the vehicle seat with the anti-submarining device.
