A seat control apparatus controls a seat of a vehicle in which an occupant of the vehicle sits. The seat control apparatus includes an occupant weight recognition unit; an occupant sitting state recognition unit configured to recognize an occupant sitting state including at least either of a grip force of the occupant and a load applied to the occupant; a lateral acceleration estimation unit configured to estimate a subsequent lateral acceleration of the vehicle; and a seat controller configured to control the seat. The seat has an occupant support adjustment portion including at least one of a first adjustment portion, a second adjustment portion, and a third adjustment portion. The seat controller calculates an adjustment amount of the occupant support adjustment portion and controls the occupant support adjustment portion in response to the calculated adjustment amount.

A seat assembly is provided with a seat frame for a seat back or a seat bottom. At least two side bolster regions are spaced apart laterally on the seat frame. At least two bolster support assemblies are provided, each bolster support assembly comprising an air bladder mounted to the seat frame along each of the side bolster regions. An actuator inflates each air bladder between a deflated position and at least one inflated support position. An accelerometer is mounted to the seat frame. A controller is in electrical communication with the accelerometer and the actuator. The controller is programmed to receive data from the accelerometer indicative of a lateral acceleration. If the lateral acceleration is above a threshold, the controller commands the actuator to inflate one of the air bladders to the inflated support position.

A vehicle seat includes a seat cushion and a seat back. The seat cushion includes a storage member configured to store fine particles, shaped into a bag, and made of a flexible and gas-impermeable material, and a gas supply/suction member. The gas supply/suction member fluidizes the fine particles stored in the storage member by supplying the gas to the storage member to make it easy to change a shape of the storage member. The gas supply/suction member solidifies the fine particles stored in the storage member by sucking the gas from the storage member to make it hard to change the shape of the storage member. The storage member includes a rigid inclined member disposed on at least one end of a periphery of the storage member and configured to be inclined downward from an outer periphery of the seat cushion toward a center of the seat cushion.

Apparatuses, systems and methods to ameliorate adverse effects upon the occupant based on predicted movements are provided. Predictions to movements of the vehicle can be accomplished by detecting operations of one or more velocity control mechanisms, and/or using various types of sensors. One or more processors can be used to derive the predicted movements, and to issue actuation signals to actuators to alter operations of the vehicle and/or a seat or other controlled devices with which the occupant interacts within the vehicle.

A system for adjusting properties of a seat for a vehicle, may include thermoelement modules configured to have a structure in which a plurality of flexible thermoelements is connected by conductive wires to each other, and mounted in a seat foam pad of the seat; a property adjustment region input unit configured to select a property adjustment region of the seat foam pad; a property adjustment amount input unit configured to input a target property adjustment amount of the seat foam pad; and a controller connected to the thermoelement modules, the property adjustment region input unit and the property adjustment amount input unit, and configured to control an amount of current supplied to some or all of the flexible thermoelements according to output signals from the property adjustment region input unit and the property adjustment amount input unit

A condition correction unit includes a plan storage unit configured to store correction plans showing contents of correction of the body condition of a seated person, a presentation unit configured to read a correction plan based on a current value measured by a measurement unit from the plan storage unit and present the correction plan to the seated person, and a processing execution unit configured to execute processing to correct posture by controlling an operating unit. The plan storage unit stores the correction plan presented by the presentation unit in association with information identifying the seated person when the correction plan is presented. The processing execution unit reads the correction plan associated with the information identifying the seated person from the plan storage unit, and executes the processing to correct the posture according to correction contents shown by the correction plan.

A motor vehicle including at least one individual seat is provided. The individual seat includes a seat part and a backrest. The seat part has a seat-part main shell and seat-part side shells arranged thereon on respective sides. The backrest has a backrest main shell and backrest side shells arranged thereon on respective sides. A rail system is provided, which moves the respective seat-part side shell and/or the respective backrest side shell in a desired or specified position by way of actuators.

A vehicle seat comprises a frame member provided on a floor of a vehicle, a seat part such as a seat cushion detachably attached to the frame member, a mechanical connector device provided on the frame member and the seat part for detachably attaching the seat part to the frame member; and an electric connector device provided on the frame member and the seat part for electrically connecting an electric component provided on the seat part to an electric component provided on the frame member.

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.

A locking block is fixed with respect to a seat cushion. A locking pin which can advance and retract relative to the locking block is provided on a main frame side. A V groove shape receptacle is formed on the locking block. When the locking pin is advanced into the receptacle portion, the locking pin is guided by a receiving inclined surface of the receptacle portion forming the V-shape groove, and advances to a bottom of the receptacle portion. With this process, the locking block moves in a rotational direction B, and when the locking pin engages the bottom, the seat cushion is fixed.
