A seat, such as a vehicle seat, includes an assembly for use in adjusting a seat support relative to a seat frame to provide a varying level of support to a seat occupant. The assembly includes a chassis mounted on the seat support, a screw drive supported on the chassis, an actuator coupled to the screw drive, a drive block engaging the screw drive, and first and second cables extending from the assembly for adjustable attachment to the seat frame.

Proposed is a lumbar support assembly including a mat formed by connecting wires in such a manner as to take shape in the form of a net and connected to a seat frame in such a manner as to be rotatable forward or backward, a tension unit comprising first and second cables, respective first end portions of the first and second cable being connected to opposite sides, respectively, of the seat frame, and respective second end portions thereof extending to the mat, and a drive unit mounted under a center portion of the mat and connected to the respective second end portions of the first and second end portions, the drive unit being configured to pull or release the first and second cables.

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.

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.

A vehicle seat having an adaptable lateral support and method of adapting lateral support are provided. The seat has a seat frame on which a seat cushion and/or a backrest cushion and at least one actuator is retained, wherein the seat cushion and/or the backrest cushion has at least one laterally arranged, resiliently deformable side wall cushion for the lateral support of a person sitting on the vehicle seat and the actuator is operationally connected to the side wall cushion and configured to apply a deformation force for the resilient deformation of the side wall cushion. The vehicle seat has a cable element which connects the side wall cushion to the actuator in a force-transmitting manner so that the actuator introduces the deformation force by tensioning the cable element directly from the cable element into the side wall cushion to deform the side wall cushion to change the lateral support.

A power seat operating device for a vehicle has a switch module for operating a power seat of the vehicle. In particular, the switch module includes a plurality of seesaw type switches to control operation directions of the power seat, and the operation directions of the power seat according to the operation of each switch is displayed with arrows on a display, thereby improving the switch operating convenience of the user such as accurately controlling the operation direction of the power seat according to the switch operation by the user, and accurately recognizing a selection state and an operation direction of the switch desired by the user.

A lumbar support system for use in an ejection seat of an aircraft, comprising may comprise a pump; a plurality of bladders fluidly coupled to the pump; and a controller electrically coupled to the pump, the controller operable to: select a bladder in the plurality of bladders to fluidly isolate the bladder from a remainder of bladders in the plurality of bladders; and command the pump to inflate the bladder.

A seat module adapted to be attached to a seat having mechanical parts and electric devices for seat operation in a motor vehicle includes at least one operating cable for activating at least one device, and a module plate formed with a mounting feature for attaching to the seat and a retention feature for attaching the at least one operating cable. An end portion of the operating cable is temporarily stowed on the module plate in a pre-assembled state where the operating cable is attached to the module plate, and the end portion of the operating cable is connected to the electric devices and/or mechanical parts of the seat in an assembled state where the module plate with the retained operating cables is securely mounted to the seat.

A lumbar adjuster for use in a vehicle seat including a lumbar mat, a frame member, and a support member. The lumbar mat is configured to face towards a backrest cushion when the lumbar adjuster is assembled to the vehicle seat. The frame member is configured to carry the lumbar mat. The support member is operatively coupled to the frame member and provided with a finger configured deflect from an extended position to a compressed position to bias portions of the lumbar mat towards backrest cushion to minimize a gap between the lumbar mat and the backrest cushion.

A lumbar support for a vehicle seat includes: a support panel made of an elastic material and supporting the user's lumbar vertebra; a first guide rod supporting the support panel; a second link bracket fastened to the first guide rod to be movable up and down; a first link bracket disposed under the second link bracket to be movable up and down with respect to the second link bracket, and having an operation block providing a supporting force to the lumbar vertebra; a first rotary screw vertically extending, thread-fastened to the first link bracket, and moving up and down the first link bracket by rotating about a longitudinal axis; and a second rotary screw vertically extending, thread-fastened to the second link bracket, and moving up and down the second link bracket by rotating about a longitudinal axis.
