A self-adaptive seat comfort system based on a fitness of occupant and seat, comprising an ECU control system, wherein the ECU control system is provided with a communication module, a microcontroller, a power supply module, a seat-occupant fitness detection module and a comfort adjustment module, where the seat-occupant fitness detection module and the comfort adjustment module are connected bidirectionally with the microcontroller through wires, and the microcontroller module is connected bidirectionally with the communication module through wires. Compared with the prior art, the present invention provides the self-adaptive seat comfort system and the adjustment method based on the fitness of occupant and seat, which can further realize intelligent dynamic adjustment, and adjust the supporting positions for various parts dynamically according to the degree of fitness of occupant and seat detected by the sensing circuit provided on the seat comfort system.

An occupant feature detection method and system, and a computer-readable medium, where the method includes: inflating a seat cushion airbag (10) with a gas of a first predetermined volume, and measuring a reference pressure formed by the gas of the first predetermined volume when no occupant is seated; measuring a first pressure formed by the gas of the first predetermined volume after an occupant is seated; and obtaining a first weight based on a difference between the reference pressure and the first pressure, and using the first weight as a reference weight of the occupant. The seat cushion airbag (10) disposed in the vehicle seat is used to calculate the weight of the occupant and determine a sitting position of the occupant based on the difference between the pressure in the seat cushion airbag (10) obtained when no occupant is seated and the pressure in the seat cushion airbag obtained when the occupant is seated. Therefore, a feature of the occupant may be identified without additionally providing a pressure sensor, so that a targeted protection strategy is set for each occupant.

Provided is a vehicle seat for use with an occupant classification system (OCS). The seat comprises: a seat base including a seat base support, and a cushion pan mounted on the seat base support and forwardly moveable on the support to extend the seat base. The seat further comprises an intermediate layer fixed with respect to the seat base support and adapted for fastening to a component of the OCS so that when the seat base is extended by the cushion pan moving forward with respect to the seat base support, the intermediate layer does not move forward with the cushion pan but remains substantially stationary. The relationship between the various OCS components can therefore be maintained irrespective of the extension of the seat base.

A seat assembly includes one or more adjustable components disposed in a seat portion or a seatback of the seat assembly and are actively operable between stowed and deployed positions based on real-time occupant position information. A controller is operably coupled to the adjustable components and configured to adjust the adjustable components towards the deployed position when a pressure force is detected by one or more sensors disposed in either the seat portion or the seatback, or both. The pressure forces are applied by the vehicle occupant as the vehicle occupant applies pressure to portions of the vehicle seat during movement of the vehicle. The adjustable components are moveable to a degree that is calculated as a function of the pressure value sensed by the sensors in the seat assembly.

A controller is operably coupled to the adjustable components and configured to adjust the adjustable components towards the deployed position when a seat occupant is seated in the seat assembly. The controller moves one or more of the adjustable components towards the deployed position until a pressure force is detected by one or more sensors disposed in either the seat portion or the seatback, or both. The pressure forces are detected by the sensors as one or more of the adjustable components contacts a vehicle occupant. Movement of the adjustable components may cease immediately when a pressure value is detected and may also continue until a threshold pressure value is reached.

A seat assembly may include a seat, a seat actuator, a sensor assembly, and an electrical control unit (ECU). The seat actuator may be configured to adjust the seat. The sensor assembly may be connected to the seat and may be configured to detect a pressure applied to the seat. The ECU may be operatively connected to the seat actuator and the sensor assembly. The ECU may be configured to reduce soft tissue stress in soft tissue of a user via adjusting the seat with the seat actuator.

A seat assembly is provided with a seat bottom and a seat back. A first actuator is oriented in a lower lumbar region. A second actuator is oriented in an upper lumbar region. A controller is programmed to operate the first actuator to adjust the lower lumbar region, and operate the second actuator to subsequently adjust the upper lumbar region to provide a seat assembly motion pattern. A third actuator is oriented in a thoracic region or a seat bottom region. The controller operates the third actuator to adjust the thoracic region or the seat bottom region after adjusting the lumbar regions to provide a seat assembly motion pattern. A plurality of sensors is provided on the seat back and the seat bottom to initiate the pattern in response to a lack of detected occupant motion to induce muscle activation upon an occupant.

A vehicle seat includes a seat bottom and a seat back. The seat back is coupled to the seat bottom and arranged to extend in an upward direction away from the seat bottom. The vehicle seat further includes an electronics system.

A seat assembly is provided with a seat bottom, and a seat back extending upright from the seat bottom. At least two side bolster actuators are spaced apart laterally and are provided in bolster regions of at least one of the seat bottom and the seat back. A plurality of sensors is operably connected to the two side bolster actuators to detect a seating position of an occupant. A controller is in electrical communication with the plurality of sensors and the two side bolster actuators. The controller is programmed to receive data from the plurality of sensors. The controller compares the data to determine if the occupant is seated evenly. The controller adjusts at least one of the two side bolster actuators to balance an uneven left-to-right occupant seating position.
