US Patent 9238425 Vehicle seat

A vehicle seat that can effectively restrain a passenger from moving outward in a vehicle width direction in the event of a collision of a vehicle is obtained. The vehicle seat disclosed is equipped with a pop-up bar that is supported displaceably upward, an MGG that is operated to displace the pop-up bar upward, a tension cloth that is connected on an upper end side thereof to the pop-up bar and on a lower end side thereof to a front end side of a seat cushion, and a lateral collision ECU that operates the MGG in a case where a lateral collision of the vehicle is detected or predicted. The tension cloth is deployed such that a tensile force is applied between a connection portion thereof to the pop-up bar and a connection portion thereof to the seat cushion as the pop-up bar is displaced to a popped-up position.
