Abstract: A seat position controller performs seat position change processing by performing longitudinal position change processing and at least one of vertical position change processing and tilt angle change processing. When the seat position controller performs the seat position change processing, a change degree setting part sets the degree of speed change in the longitudinal direction of a seat main body during the longitudinal position change processing smaller than the degree of speed change in the vertical direction of the seat main body during the vertical position change processing, and the degree of speed change in a tilt angle direction of a seat back during the tilt angle change processing.

A detection target portion is provided in the upward wall portion of the lower rail in a predetermined range in the longitudinal direction of the lower rail. A position sensor is disposed at the upper rail between the upper rail and the upward wall portion to face the detection target portion.

Abstract: A vehicle seat of the present invention includes: a seatback frame which has side frame sections on both sides thereof in a seat width direction; a load transmission member which projects toward an outside in the seat width direction from one of the side frame sections and transmits an impact load input from a side of a vehicle body to the seatback frame; and a side airbag device which is provided with an inflator which generates a gas when the impact load is input and a folded bag body to be deployed when the pressure of the gas is received. The inflator is attached to the load transmission member or the side frame section, and the bag body is disposed at a position which is further outside than a gas discharge port of the inflator in the seat width direction and is opposed to a surface facing the vehicle front side of the load transmission member.
