Abstract
An ergonomic weight support device for a seat has a flexible pressure plate attached to an extending paddle for lumbar support. The paddle extends from a housing having a channel into which the paddle may be retracted for the lumbar support to be flat, or from which the paddle may be extended for lumbar support. The flexible pressure plate distributes lumbar supporting pressure across a greater area for comfort.
Claims19
An ergonomic weight support device for a seat comprising:
- a housing having an engaging channel;
- a paddle having a pressure surface end, said pressure surface end being oriented towards a seat occupant, and said paddle having an engaged end, said engaged end being in extendible communication with said channel of said housing;
- an actuator that mediates travel of said paddle between a substantially retracted position and an extended position;
- and
- a pressure plate attached to said pressure surface end of said paddle.
An ergonomic weight support for a seat comprising:
- a housing;
- an paddle extendably engaged with said housing;
- means for exending said paddle from a retracted position in said housing to an extended position;
- a pressure plate;
- and
- means for attaching said pressure plate to said paddle.
An ergonomic weight support apparatus for a seat comprising:
- a housing having an arcuate channel defined by at least one guide boss;
- an extending element having a pressure surface end, said pressure surface end being convex toward a seat occupant and being flexible in response to pressure, said extending element also having an arcuate encapsulated end slidingly disposed within said channel of said housing;
- an actuator anchored to said housing;
- a traction element having a first end engaged with said actuator and a second end in tractive communication with said arcuate encapsulated end of said extending element;
- and
- a pressure plate attached to said pressure surface end of said extending element;
- whereby said actuator mediates travel of said extending element between a retracted position and an extended, weight supporting position.
A method of distributing the pressure of a lumbar support comprising:
- Disposing an extendible pressure surface in a housing channel to travel from a retracted position to an extended position;
- Mediating said travel with an actuator;
- and
- Attaching a pressure plate to said extendible pressure surface.
