A multidirectional control apparatus for a vehicular seat is provided to perform anteroposterior tilting, lateral tilting, control of height and tilting in other directions in consideration of the body size of a passenger and the traveling environment. The multidirectional control apparatus improves passenger comfort by tilting the seat in a lateral direction when entering or exiting a vehicle, prevents the passenger from leaning to one side by tilting the seat in a lateral direction during turning of the vehicle, and offers a safety function of protecting the passenger by inclining the seat in the direction of a collision in the event of a collision of the vehicle.

An extensively reconfigurable seat design can include a vehicle seat system including: a vehicle seat defining a vehicle occupant accommodating space, the vehicle seat including a seat cushion portion including multiple individually adjustable bladders, where each of the multiple individually adjustable bladders has a connected valve that controls fluid communication with an internal space of the individually adjustable bladder to adjust a pressure level within the internal space of the individually adjustable bladder, and an associated sensor configured to detect the pressure level within the internal space of the individually adjustable bladder. A computer can actively sense and control the pressure levels within the bladders, using the sensors and valves, to provide customization, adaptive, ride-active and intelligent control over a reconfigurable cushion for a vehicle.

A controller, which serves as a pressure-feeding control portion, drives an air pump to pressure-feed air to massage airbags located in a seat. In addition, the controller, which serves as an inflation-deflation control portion, performs massage control that inflates and deflates the airbags while keeping the air pump driven by controlling the operation of intake-discharge valves in second flow passage (branch lines), which connects the air pump to the airbags. Furthermore, the controller, which serves as a decompression control portion, opens a discharge valve, which is located upstream of the intake-discharge valves, in a state in which the airbags are deflated during the massage control.

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 seat bolster control system for a vehicle seat including an adjustable seat with adjustable bolsters, a sensor capable of sensing a position of the adjustable seat, a controller in communication with the sensor and an adjusting device which can control adjustment of the adjustable bolsters. The seat bolster control system can automatically adjust based on the position of the adjustable seat, such as if the adjustable seat moves away from a neutral position.

A kinetic seat back assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat back assembly includes a primary seat back frame, a secondary seat back frame, a seat back tilt mechanism coupling the secondary seat back frame to the primary seat back frame such that the secondary seat back frame is movable with respect to the primary seat back frame, and an upper pivot mechanism that pivotally couples an upper portion of the primary seat back frame to an upper portion of the secondary seat back frame.

A kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.

A kinetic seat cushion assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat cushion assembly includes a primary seat cushion frame, a secondary seat cushion frame, a seat cushion tilt mechanism coupling the secondary seat cushion frame to the primary seat cushion frame such that the secondary seat cushion frame is movable with respect to the primary seat cushion frame, and a front pivot mechanism that pivotally couples a front portion of the primary seat cushion frame to a front portion of the secondary seat cushion frame.

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.
