Fluid management system

A pneumatic module has an air passage formed therein, including an air inlet to receive a source of pressurized air, a first subsystem with an air splitter in fluid communication with the air inlet, a second subsystem, and a third subsystem. The air splitter is configured to create two unequal air pressure fields to deflect an airflow from the air inlet to the second subsystem. The second subsystem is configured to create two unequal air pressure fields to deflect the airflow toward a first air bladder to inflate the first air bladder, and when the first air bladder reaches a first threshold air pressure, a first backpressure from the first air bladder causes the second subsystem to switch and deflect the air flow to a second air bladder. A second backpressure causes the air splitter to switch and deflect the airflow from the second subsystem to the third subsystem.

A pneumatic system includes a passage to discharge compressed air and a sound attenuator including a first chamber in fluid communication with the passage and defined by a first wall through which the passage opens into the first chamber, a first surface of a second wall spaced from and opposite the first wall, and a sidewall extending between the first and second walls. The first chamber has a volume and includes a first opening in the sidewall. A second chamber is in fluid communication with the first opening and partially surrounds the first chamber. The second chamber is partially defined by a second surface of the second wall opposite the first surface and by the sidewall, and the second chamber has a volume and includes a second opening to exhaust air from the second chamber. The volume of the first chamber is less than that of the second chamber.

A fluidic switching module body defining an inlet passage, a first nozzle in fluid communication with the inlet passage, an air splitter in fluid communication with the first nozzle, and a first transfer passage in fluid communication with a first side of the air splitter. A second transfer passage is in fluid communication with a second side of the air splitter, a second nozzle is in fluid communication with the first transfer passage, and a second air splitter is in fluid communication with the second nozzle. A first bladder passage is in fluid communication with a first side of the second air splitter, and a second bladder passage is in fluid communication with a second side of the second air splitter. A first vent passage is in fluid communication with the first bladder passage, and a second vent passage is in fluid communication with the second bladder passage.

A pneumatic system includes a fluidic switching module having an air passage and a vent in fluid communication with the air passage. The pneumatic system also includes a sound attenuator coupled to the fluidic switching module, the sound attenuator having a first chamber in fluid communication with the vent, a first orifice in fluid communication with the vent via the first chamber, a second chamber in fluid communication with the first chamber via the first orifice, and a second orifice in fluid communication with the first orifice via the second chamber.

A lumbar support system for a seat backrest, the lumbar support system includes a carrier having a first end and a second end opposite the first end. The carrier is movable with respect to the seat backrest in a first direction and in a second direction opposite the first direction. The lumbar support system further includes a first bladder coupled to the first end of the carrier, a second bladder coupled to the second end of the carrier, and a third bladder coupled to the carrier. The third bladder has a contact surface and is configured to move with the carrier. The first bladder is inflatable to move the carrier in the first direction, and the second bladder is inflatable to move the carrier in the second direction. The third bladder is inflatable such that the contact surface is extendable in a third direction.

Pneumatic four way lumbar

A lumbar support system for a seat backrest includes a fixed frame and a flexmat coupled to the fixed frame. The flexmat includes first and second outer wires and a plurality of transverse wires extending between the outer wires. A support element is coupled to a lower portion of the flexmat below the plurality of transverse wires for concurrent movement with the flexmat from a first position to a second position. The support element is anatomically contoured for lumbar and pelvic support, and the support element is constructed of a more rigid material than the flexmat.

Lumbar support system

An actuator includes a motor, a gear assembly, a pulley selectively rotatable about an axis by the motor via the gear assembly, at least one biasing member, a first cable connected at one end to the pulley, and a second cable connected at one end to the pulley. The pulley is rotatable in a first pulley direction to a first actuation position to increase tension in the first cable and is rotatable in a second pulley direction opposite the first pulley direction to a second actuation position to increase tension in the second cable. The at least one biasing member is operable to bias the pulley in the second pulley direction when the pulley is in the first actuation position and to bias the pulley in the first pulley direction when in the pulley is the second actuation position.
