Abstract
A pump assembly for a vehicle seatback includes a plurality of air bladders defining a lumbar support. A valve body has an inlet and a plurality of outlets that are coupled with the associated plurality of air bladders. A selection device is operably coupled with the valve body for engaging a select one of the plurality of air bladders with the inlet. A manually compressible air chamber is coupled with the inlet for inflating the select one.
Claims20
A pump assembly for a vehicle seatback, comprising:
- a plurality of air bladders defining a lumbar support;
- a valve body having an inlet and a plurality of outlets coupled with the associated plurality of air bladders;
- a selection device operably coupled with the valve body for engaging the inlet with a select one of the plurality of air bladders;
- and
- a manually compressible air chamber including a resiliently-deformable bulb coupled with the inlet for inflating the select one of the plurality of air bladders;
- a lever having a first lever arm pivotally coupled about a first pivot axis relative to the manually compressible air chamber and movable to compress an interior cavity of the manually compressible air chamber for dispensing air to the inlet, the lever comprising a second lever arm having an elongated projection extending from the first lever arm;
- and
- a clamp defining a fixed base portion and a moveable clamp portion, the base portion and clamp portion being oppositely disposed on respective sides of an exterior of the resiliently-deformable bulb the elongated projection pivotally coupled about a second pivot axis on the moveable clamp portion to drive movement thereof to compress the compressible air chamber.
A lumbar pump assembly comprising:
- first and second air bladders defining a lumbar support;
- a valve body fluidly coupled with the first and second air bladders;
- an air chamber including a resiliently-deformable bulb and having an exhaust port fluidly coupled with the valve body and configured to manually dispense air therefrom;
- a lever having a first lever arm pivotally coupled about a first pivot axis relative to the air chamber and movable to compress an interior cavity of the air chamber for dispensing air to the valve body, the lever comprising a second lever arm having an elongated projection extending from the first lever arm;
- a clamp defining a fixed base portion and a moveable clamp portion, the base portion and clamp portion being oppositely disposed on respective sides of an exterior of the resiliently-deformable bulb the elongated projection pivotally coupled about a second pivot axis on the moveable clamp portion to drive movement thereof to compress the air chamber;
- and
- a selection device that selectively engages the exhaust port with the first and second air bladders.
A lumbar pump assembly comprising:
- a seatback having a plurality of air bladders disposed thereon to define a lumbar support;
- an air chamber including a resiliently-deformable bulb and having an intake port for receiving ambient air and an exhaust port for dispensing air upon compression of the air chamber;
- a lever having a first lever arm pivotally coupled about a first pivot axis relative to the chamber and movable for manually compressing the air chamber to compress an interior cavity of the air chamber for dispensing air from the exhaust port, the lever comprising a second lever arm having an elongated projection extending from the first lever arm;
- a clamp defining a fixed base portion and a moveable clamp portion, the base portion and clamp portion being oppositely disposed on respective sides of an exterior of the resiliently-deformable bulb, the elongated projection pivotally coupled about a second pivot axis on the moveable clamp portion to drive movement thereof to compress the compressible air chamber;
- a valve body having an inlet fluidly coupled with the exhaust port and a plurality of outlets coupled respectively with the plurality of air bladders;
- and
- a selection device coupled with the valve body for selectively engaging the inlet with a select one of the plurality of outlets for inflating the respective air bladder.
