  • Patent number: 10793042
    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.

  • Patent number: 9586500
    Abstract: A slide rail of a vehicle seat includes a first rail to which a screw having a screw thread formed on an outer periphery is fixed, and a second rail that retains a nut into which the screw screws, and moves relative to the first rail by the nut rotating. The first rail has a through-hole into which the screw is inserted. At least one end of the screw has a deformed portion that is deformed toward an outside in a radial direction of the screw with respect to the first rail while the at least one end of the screw is in a state passing through the through-hole, and that keeps the screw from slipping out of the through-hole.
