A pressure medium distributor, for a pneumatic adjustment arrangement of a vehicle seat. The pressure medium distributor has a distribution element including at least one first and one second film connected to each other along a connection seam in order to form a first and at least one second pressure medium chamber. The pressure medium distributor has a first pressure medium inlet line to admit the pressure medium into the first pressure medium chamber, and at least one second pressure medium inlet line to admit the pressure medium into the at least one second pressure medium chamber, At least one first pressure medium outlet line is provided for discharge of the pressure medium from the first pressure medium chamber, and at least one second pressure medium outlet line is provided for discharge of the pressure medium from the second pressure medium chamber creating a pressure medium distributor which is flexible.

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 vehicle seat includes: a seat back having an upper frame; a fan provided in the seat back; a lumbar plate that is provided in the seat back and elastically supports a waist of a seated occupant from a rear side; and a support member that elastically supports the fan in an area at a height between the lumbar plate and the upper frame.

A flexible lumbar support for an aircraft seat includes a frame and flexible seat pad connected thereto for supporting a seat user. At least first and second rods are spaced from each other and the frame, extend across and are secured to the seat pad, and define respectively at least first and second control lines about which the seat pad is rotatable. A third rod is spaced from the seat pad, extends across and is secured to the frame, and defines a third control line. At least a first actuator extends between and is attached to the first and third rods. A second actuator extends between and is attached to the second and third rods. The actuators are movable along the frame and pivotable about the third control line for allowing a change of respective positions of the control lines to generate multiple profiles of the flexible lumbar support.
