  • the application relates to a recliner chair with a backrest pivot lin kage that allows the backrest to pivot between an upright position and a reclining position.
  • a typical recliner chair 10 as shown on FIG . 1, includes a chassis 12 that supports a seat 14, a backrest 16, and a leg rest 18 by way of a reclining carriage 20.
  • An example of a typical reclining carriage 20 is shown in detail in FIGS. 2A-2C.
  • the reclining carriage 20 allows the backrest 16, the seat 14, and the leg rest 18, to shift between an upright position shown in solid lines, an extended position shown in first dashed lines, and a reclining position shown in second dashed lines. I n the upright position, the backrest 16 is tilted in a generally u pright orientation, the seat 14 is in a generally horizontal position, and the leg rest 18 is retracted in a generally downward position .
  • the seat 14 and backrest 16 are translated forward with respect to the chassis 12 but remain in the generally upright and generally horizontal positions, respectively, while the leg rest 18 is extended and pivoted upward ly to a generally horizontal position .

  • the recliner chair 10 can recline with zero clearance distance between the backrest 16 and a wall. This is possible because of the forward translation of the seat 14 and the backrest 16 on the reclining carriage 20 when shifting from the upright position to the reclining position .
  • FIGS. 2A, 2B, and 2C the reclining carriage 20 is shown in detail in the upright position (FIG. 2A), the extended position (FIG. 2B), and the reclining position (FIG.

Abstract

L'invention concerne un fauteuil inclinable (50) et une poussette inclinable (52), comprenant l'un et l'autre un accouplement pivotant de dossier (54) pour un dossier (16) qui tourne autour d'un premier point (56) et d'un second point (58), et les points de pivotement (56, 58) se déplacent vers et à l'écart d'un boîtier de siège (60) et/ou d'un siège (14). Dans certains agencements, l'accouplement pivotant de dossier (54) permet à une région de soutien lombaire (46) du dossier (16) de maintenir un contact sensiblement constant ou immobile avec la région lombaire d'une personne s'asseyant dans le fauteuil inclinable (50) alors que le fauteuil inclinable (50) passe entre la position dressée et la position inclinée, et améliore le confort de la personne.
