Abstract: A vehicle seat includes an air bag, and a controller. The air bag is for holding a posture of an occupant and configured to inflate as air flows in or deflate as air flows out of the air bag. The controller is configured to receive an input of a signal based on a steering angle of the vehicle and to control inflation or deflation of the air bag based on the signal. The controller is configured to enable an active-support mode to cause air to flow inside the air bag in response to the steering angle becoming greater than or equal to a predefined given angle.

Abstract: A pneumatic tire comprises a carcass comprised of one or more carcass plies and a belt disposed on an outer periphery side of a crown portion of the carcass and comprised of one or more belt layers, wherein each of at least one carcass ply and at least one belt layer is constituted with organic fiber cords having a modulus of elasticity within a specified range.

Abstract: A pneumatic radial tire includes a carcass ply formed from one radial cord layer, a belt and tread disposed at a crown portion radial direction outer side of the carcass ply, and bead fillers and bead reinforcing layers disposed at the bead portions, wherein the carcass ply is formed from a carcass ply main body extending from one bead portion to another, and carcass ply turn-over portions wound about bead cores and extending toward radial direction outer sides. The bead filler is interposed between the carcass ply main body and the carcass ply turn-over portion, and tapers from directly above the bead core toward a radial direction outer side. The bead reinforcing layer is interposed between the carcass ply main body and the bead filler. An upper end of the bead reinforcing layer extends along the carcass ply main body to a position at 30 to 80% of a tire cross-sectional height, and is disposed further toward a radial direction outer side than an upper end of the bead filler.
