The invention relates to an automobile seat with a seat cushion changeable in rigidity. The automobile seat comprises a seat back, a seat basin, and the seat cushion arranged on the seat basin. One or a plurality of baffle units are arranged between the seat basin and the seat cushion. Each baffle unit comprises a baffle, a first spring and a second spring, wherein the first spring and the second spring are arranged between the baffle and the seat basin, one end portion of the baffle is connected with the front end portion of the seat basin through the first spring, the other end portion of the baffle is suspended and is located above the middle end portion of the seat basin, one end of the second spring is fixedly connected with the seat basin, and the other end of the second spring is suspended. The automobile seat can effectively reduce the risk that passengers are submerged and hurt at automobile collision time, can be effectively matched with a child seat anti-turning device for utilization when is applied to a back row seat provided with a child safe seat, and reduces turning risks of the child seat in the collision process.
Description
technical field [0001] The invention mainly relates to a car seat with variable cushion stiffness, which belongs to the field of occupant restraint systems. Background technique [0002] In the event of a frontal collision, the front and rear passengers are prone to dive, resulting in injuries to the abdomen and lower limbs. In order to improve the ride comfort, the front co-pilot adjusts the seat to the receding state, which is more prone to the risk of diving in the event of a collision. In addition, when a child seat is installed on the car seat, the child seat fixed on the rear seat of the car has a tendency to flip forward during a frontal collision of the car, which poses a threat to the life safety of the child occupant. Studies have shown that increasing the stiffness of the car seat cushion during a collision can provide comprehensive protection for all types of occupants in the above working conditions. [0003] Under the normal driving conditions of the car, the...
