Abstract: A vehicle seat installed in a vehicle includes a seatback, a seat cushion, a seat frame, a movable part, a first spring, a second spring, and a preloading device. The first spring is capable of, when the movable part has shifted in a first direction, generating such an elastic force as causes the movable part to shift toward the neutral position. The second spring is capable of, when the movable part has shifted in a second direction, generating such an elastic force as causes the movable part to shift toward the neutral position. The preloading device is configured to change at least one of the elastic force exerted on the movable part by the first spring and the elastic force exerted on the movable part by the second spring.

Abstract: The transfer assistance device includes a bogie, an arm tiltably supported by the bogie, a holding part that is supported by the arm and holds a torso of a person being assisted. The holding part includes at least a low pressure cell group and a high pressure cell group configured to respectively face different parts of a front surface of the torso of the person being assisted. The transfer assistance device further includes air pressure adjuster configured to individually adjust air pressure of the low pressure cell group and air pressure of the high pressure cell group.
