A lumbar adjuster for use in a vehicle seat and including a wire frame, a lumbar mat, an adjustment mechanism, and an arbor. The wire frame configured to be fixed to a backrest and including a first lateral portion, a second lateral portion and a transverse portion extending therebetween. The lumbar mat configured to face towards a backrest cushion when the lumbar adjuster is assembled to the vehicle seat. The adjustment mechanism connected to and configured to move along the first and second lateral portions and including a lever arm and a gear train operatively connected to and operable to articulate the lever arm to move a portion of the lumbar mat towards and away from the backrest cushion. The arbor connected to the transverse portion of the wire frame and the adjustment mechanism to fix the adjustment mechanism relative to the transverse portion.

An apparatus for a vehicle seat for mobilizing at least one region of a spinal column of a seat occupant sitting in the seat may have a plurality of expandable elements, which may be each filled or fillable with a medium. The expandable elements are drivable sequentially. A method for sequentially driving the apparatus and and a vehicle seat are also provided.

A seat assembly includes a cushioned component having a lattice matrix. An air bladder assembly is covered by the lattice matrix. The air bladder assembly includes a plurality of air bladders supported on a platform assembly. Each air bladder includes a body portion operable between deflated and inflated conditions. Each air bladder includes a connection stem. A support plate includes a plurality of access apertures disposed therethrough. The air bladder assembly is operably coupled to the support plate. Each air bladder is aligned with at least one access aperture of the plurality of access apertures. A carrier assembly includes a plurality of mounting apertures disposed through an outer surface thereof. The carrier assembly receives the connection stem of each air bladder through at least one mounting aperture of the plurality of mounting apertures. Each air bladder may include a release valve for releasing air therethrough.

A vehicle seat provided in a vehicle includes: a seat body including a seat cushion and a seatback; an occupant support device displaceably provided on the seat body to press an occupant seated on the seat body; a notification device provided on the seat body to make notification to the occupant; an information acquisition device that acquires information including at least one of a surrounding environment of the vehicle and a driving state of the vehicle; and a control device that controls the occupant support device and the notification device based on the information. The notification device may be provided on the occupant support device. When the vehicle turns, the control device may cause the vibrator disposed on a side opposite from the turning direction to vibrate.

Seat assemblies and subassemblies are disclosed. The subassemblies include massage and/or ventilation subassemblies that employ tubeless air distribution by fixing sheets together such as by heat-staking. The subassemblies also include a support structure for preassembling the massage, ventilation, and/or electronic components together prior to suspending them in a seat assembly.

A seat assembly is provided with a pump for a fluid system, such as an air system. The pump has a housing with a wall surrounding a recess, with the housing defining an inlet passage and an outlet passage. A diaphragm is positioned through the wall with a distal end within the recess, and with the inlet and outlet passages in fluid communication with an opening to the pumping chamber of the diaphragm. A cam is supported for movement along a path about a central axis within the recess, and is connected to the distal end region of the diaphragm. The cam alternately moves the distal end region radially outwardly from the central axis to compress the pumping chamber and provide flow to the outlet passage, and moves the distal end region radially inwardly towards the central axis to expand the pumping chamber and provide flow into the pumping chamber.

A vehicle seat including a seat assembly and an insert assembly. The seat assembly having a seat base portion, a backrest portion. The insert assembly includes upper inserts, lower inserts, and a lumbar cushion. The upper inserts are filled with a combination of a silicone anti-freezing solution and small extruded polystyrene packing balls. The lower inserts are filled with jelly. The upper and lower inserts are mounted within the seat base portion and backrest portion. The lumbar cushion is mounted inside the backrest portion. The conjunction of the lower insert, upper insert and lumbar cushion are configured to bring maximum comfort to a user. The upper inserts, lower inserts and lumbar cushion are configured to bring a user an exceptional stability and support without pressure applied to a tailbone.
