Title
(EN) LUMBAR SUPPORT ADJUSTMENT
(FR) AJUSTEMENT D'UN SUPPORT LOMBAIRE
Abstract
(EN)
An adjuster operable to vary the tension in a lumbar support band (2) which in use extends transversely across a seat backrest. The adjuster includes a mounting (4, 6) and a drive mechanism (9) which connects one end of the support band (2) to the mounting (4, 6). The drive mechanism (9) has a longitudinal axis which extends generally in the longitudnal direction of the lumbar support band (2), and the mechanism includes two spindle parts (10, 11) which are telescopically arranged and which coact in a manner such that their combined longitudinal extent varies in response to relative rotation about the longitudinal axis. One part (10) also coacts with the mounting (4, 6) in a manner such that relative rotation between that part (10) and the mounting (4, 6) causes the part (10) to move longitudinally relative to the mounting (4, 6). It is a feature of the arrangement that when one part (10) moves longitudinally in one direction relative to the mounting (4, 6), the other part (11) also moves longitudinally in the same direction relative to both the first mentioned part (10) and the mounting (4, 6). The coaction between the spindle parts (10, 11) and the coaction with the mounting (4, 6) is preferably achieved through cooperable screw threads (12, 13, 14).
(FR)
Dispositif d'ajustement permettant de faire varier la tension dans une bande de support lombaire (2) qui, en utilisation, s'étend transversalement dans un dossier d'un siège. Le dispositif d'ajustement comprend un mécanisme de montage (4, 6) et un mécanisme d'entraînement (9) qui relie une extrémité de la bande de support (2) au montage (4, 6). Le mécanisme d'entraînement (9) possède un axe longitudinal qui s'étend généralement dans le sens longitudinal de la bande de support lombaire (2), et le mécanisme comprend deux parties de broches (10, 11) qui sont disposées de manière télescopique et qui agissent de concert afin que leur étendue longitudinale combinée varie en réponse à la rotation relative autour de l'axe longitudinal. Une partie de broche (10) agit également de concert avec le montage (4, 6) afin que cette rotation relative entre cette partie de broche (10) et le montage (4, 6) provoque le déplacement longitudinal de la partie (10) par rapport au montage (4, 6). L'agencement se caractérise en ce que, lorsque la partie (10) se déplace longitudinalement dans un sens par rapport au montage (4, 6), l'autre partie (11) se déplace également longitudinalement dans le même sens par rapport à la fois à la première partie mentionnée (10) et au montage (4, 6). L'action combinée entre les parties de broche (10, 11) et le montage (4, 6) s'effectue de préférence par l'intermédiaire des filetages coopérants (12, 13, 14).
