A method is described for adapting a position of a seat device of a passenger of a vehicle during and/or prior to a switchover of the vehicle from an automated driving mode to a manual driving mode, the method having at least a step of providing, in which an adjustment signal is provided to an interface to a seat device of the vehicle using a transition signal and a position signal, and the adjustment signal causes a change in the position of the seat device from a comfort position to an upright position, and the transition signal indicates or represents an upcoming transition from an automated driving mode to a manual driving mode of the vehicle, and the position signal indicates or represents the position of the seat device of the passenger, the provision of the adjustment signal taking place when the position signal indicates or represents the comfort position, and/or the provision not taking place when the position signal indicates or represents the upright position; and/or providing a blocking signal in response to the transition signal when the position signal indicates or represents an upright position, the blocking signal blocking an adjustment of the upright position to a comfort position by the passenger.

The present invention relates to a vehicle sheet with a seat back which is provided with a urethane pad covered with a trim cover, and a pressing unit on the reverse side of the urethane pad covered with the trim cover, the pressing unit being formed with a shaft extending laterally and a pair of pressure portions arranged in the vertical direction with respect to the shaft to support both the upper and lower sides of the urethane pad by detecting the intermediate position of turning movement of the pressing unit by means of a turning movement detection unit and stopping the turning movement of the pressing unit, or is configured to press forward the upper side of the urethane pad using the upper pressure portion or the lower side of the urethane pad using the lower pressure portion by turning the laterally-extending shaft of the pressing unit.

A vehicle seat includes a seat cushion configured to support the buttocks of an occupant, a seat back configured to support the back of the occupant, an elastic force adjustment unit configured to adjust elastic force of a lumbar spine support of the seat back configured to support the lumbar spine of the occupant, in a longitudinal direction, and a controller configured to operate the elastic force adjustment unit. The controller is configured to make the elastic force larger in the case where oscillation of the vehicle is large, than that in the case where oscillation of the vehicle is small.

An occupant protection device including: a side support section; a lumbar support section that is provided to the width direction intermediate portion of the seatback, and that has a support face displaceable between an advanced position pressing the lumbar region and a retreated position further to a seatback rear side than the advanced position; a displacement mechanism that displaces the support face of the lumbar support section between the advanced position and the retreated position; a side collision prediction section; an actuation controller that, in a case in which a vehicle side-on collision has been predicted by the side collision prediction section in a state in which the support face of the lumbar support section is not at the retreated position, controls the displacement mechanism so as to displace the support face of the lumbar support section to the retreated position.

A vehicle seat provided with a seat cushion and a seat back, wherein the seat back is provided with: a urethane pad in which the surface is covered by a trim cover; and a pressure means in which a laterally extending shaft and a pair of pressing parts in the vertical direction relative to the shaft are formed on the reverse side of the urethane pad toward the side covered by the trim cover, and a configuration is adopted such that the shaft extending in the lateral direction of the pressure means rotates or swings, thereby causing the upper-side pressing part among the upper and lower pair of pressing parts to press the upper side of the urethane pad forward and the lower-side pressing part to press the lower side of the urethane pad forward.

A back support device, comprising: a frame portion provided at a seat on which a seated person is seated, the frame portion including a locked portion at an upper portion of the frame portion; an upper frame portion fixed to the upper portion of the frame portion and extending in a seat width direction below the locked portion; a lumbar support portion engaged with a lower portion of the frame portion and configured to support a waist of the seated person from a seat rear side; and a pressure receiving portion including, at an upper end portion thereof, a locking portion locked to the locked portion, the pressure receiving portion being supported by the upper frame portion and the lumbar support portion from the seat rear side, and being configured to be deformable by receiving a load from a back of the seated person.

Proposed is an actuator for a recliner which can be manufactured with components having simple structures to reduce weight, and functions of a seat operated through different cables are independently performed stably. The actuator for a recliner includes: a casing part, and a drive part provided with a worm wheel gear located inside the casing part and rotated by an operation of a motor, and a rack gear configured to move elastically toward a first or second side of the drive part in engagement with the worm wheel gear, with cables being coupled respectively to the first and second sides of the rack gear.

It is provided an adjusting device of a lumbar support or a side-bolster adjuster for changing the contour or position of a seat element of a vehicle seat supporting a body part of a seat user, with at least one driving device comprising a spindle drive and at least one adjustable support element for changing the contour or position of the seat element, wherein the spindle drive comprises a spindle extending along a spindle axis, which on a fastening part of the lumbar support or the side-bolster adjuster mounted in the vehicle seat is floatingly mounted at a spindle end via a spindle holder such that at this spindle end the spindle is displaceable along at least one spatial direction extending transversely to the spindle axis.

A vehicle seat including a panel and an actuating mechanism. The panel includes an elastomeric material. The actuating mechanism is connected to the panel. The actuating mechanism is configured to alter a contour of a seating surface of the panel.

An actuator assembly for adjusting at least one component of a seat comprises a first traction device, a second traction device, and an actuator which comprises a spindle drive. The spindle drive comprises a first member which is rotatably mounted and a second member which is threadingly engaged with the first member and secured against rotation. Both the first traction device and the second traction device are coupled to the second member of the spindle drive.
