Abstract
A movable seating arrangement includes a seat pan, a back support rigidly connected with the seat pan, and a seat member slidably mounted to the seat pan. The seat member can be moved from a retracted position proximate the back support to an extended position displaced forward of the upright position, without movement of the back support. In certain embodiments, a lumbar support is mounted to the back support, and motion of the seat member to its extended position causes a mid portion of the lumbar support to flex forward from a flattened position.
Claims20
A movable seating arrangement comprising:
- a seat pan;
- a back support attached to the seat pan;
- and
- a seat member slidably mounted to the seat pan;
- wherein the seat member is movable from a retracted position proximate the back support to an extended position displaced forward of the retracted position, without imposing movement of the back support.
A movable seating arrangement comprising:
- a seat pan;
- a seat member slidably mounted on the seat pan and movable between a retracted position overlying the seat pan and an extended position partly overlying the seat pan at a forward edge thereof;
- and
- a lumbar support having a lower portion fixedly connected with the seat pan, an upper portion movably connected with the seat member, and a flexible mid portion,
- wherein motion of the seat member to its extended position causes the mid portion of the lumbar support to flex forward from a flattened position.
A movable seating arrangement comprising:
- a seat pan configured for attachment to a pre-existing seat structure, with a rearward edge of the seat pan adjacent a back support portion of the pre-existing seat structure;
- and
- a seat member slidably mounted on the seat pan and movable between a retracted position overlying the seat pan and an extended position partly overlying the seat pan at a forward edge thereof,
- whereby, while the seat pan is attached to a pre-existing seat structure, an occupant can move the seat member between retracted and extended positions without moving a back support portion of the pre-existing seat structure.
A movable seating arrangement comprising:
- a seat frame including an upright back portion and a horizontal pan portion;
- a seat member slidably mounted on the pan portion of the seat frame and movable between a retracted position proximate the back portion and an extended position distal from the back portion;
- and
- a lumbar support mounted to the seat frame and movable between a retracted position against the back portion of the seat pan and an extended position away from the back portion,
- wherein the lumbar support is connected with the movable seat member to move jointly between the retracted and extended positions.
