Provided is a conveyance seat including a pelvis support member of which a state or the like is adjusted. The conveyance seat includes the pelvis support member configured to support a portion of an occupant's body where a pelvis is positioned and lumbar supports configured to move the pelvis support member. The pelvis support member includes a seat back side support portion positioned behind a back portion of the occupant, a seat cushion side support portion positioned below buttocks of the occupant, and a connection portion that connects the seat back side support portion and the seat cushion side support portion. The lumbar supports are configured to move the pelvis support member so that a position of at least one of the seat back side support portion, the seat cushion side support portion, and the connection portion is changed with respect to the portion where the pelvis is positioned.

A seat assembly may include a seat having a seat base and a seat back, a temperature control unit disposed at least partially in the seat back, and/or an ECU connected with the temperature control unit. The ECU may be configured to receive an input related to (i) a first state corresponding to symptoms and/or discomfort associated with dysmenorrhea and/or (ii) a second state corresponding to symptoms and/or discomfort associated with sciatica. The ECU may be configured to operate the seat assembly according, at least in part, to the input.

Disclosed is a system for correcting a passenger's posture in an autonomous vehicle, wherein the system includes a camera configured to measure a distance between a headrest and a head of the passenger, a plurality of body pressure sensors configured to be uniformly embedded across an entire area of the seat and sense body pressures of the passenger, a pressurizing device configured to be expandably installed inside a seatback and press between T10 and T12 of a thoracic spine of the passenger, and a controller configured to control an operation of the pressurizing device on the basis of the distance measured by the camera and a scapular pressure of the passenger, which is sensed by the plurality of body pressure sensors.

The object of the invention is to provide a vehicle seat which can improve degree of freedom in the design of the vehicle seat. A vehicle seat with a seat cushion and a seat back includes: right and left side frames 20 constituting right and left frames of the seat back; a pressure-receiving member 40 disposed between the right and left side frames 20 and configured to receive a load from an occupant; and a driving mechanism 50 disposed at each of right and left sides of the pressure-receiving member 40 and configured to cause a right end portion or a left end portion of the pressure-receiving member 40 to move from an initial position to an advanced position that is located frontward of the initial position or to move from the advanced position to the initial position, wherein the driving mechanism 50 includes a linkage (drive link member 100 and contact link member 200) configured to be connected to the pressure-receiving member 40 and a driving source 52 configured to actuate the linkage, and wherein the linkage is configured to operate when a load equal to or greater than a predetermined amount is input from the occupant to the pressure-receiving member 40 to cause the pressure-receiving member 40 to move to a backward position that is located rearward of the initial position.
