Title (EN) CHAIR AND SEAT-BACK UNIT THEREFOR
(FR) CHAISE ET ENSEMBLE SIEGE-DOSSIER
Abstract: front page image
(EN)A seat-back unit for a chair utilizes pre-flexed sheets of sinuous spring wire material (29) connected to relatively rigid side support members which afford flexibility, but provide a frame for the unit. The two L-shaped side support members (26) are held apart by a rigid cross stretcher member (28) positioned in the seat portion, near the back. The seatback unit is connected to a chair frame at only four points in a "cradling" arrangement, by means of a pair of hooks (33) extending back from the tops of the relatively rigid members, received in slots (34) of the chair frame, and by bolted connections (36, 60) of the relatively rigid members at the front of the seat portion to the chair frame. The seat-back unit, and particularly the relatively rigid frame members, are put into a pre-stressed condition as the seat portion is connected to the chair frame. Covering material, which may be removable, is positioned over the seat-back unit. A simple chair frame structure is preferably used, with an X-shaped bracing configuration at the bottom and four upright legs. This may be accomplished with two tubular members, each formed into a front and a rear leg, and an angled portion of a brace, with the portions connected together centrally.
(FR)Un ensemble siege-dossier d"une chaise utilise des lames prepliees en un materiau de fils metalliques sinueux faisant ressort (29) reliees a des supports lateraux relativement rigides qui permettent une flexibilite mais forment un cadre pour l"ensemble. Les deux supports lateraux en forme de L (26) sont maintenus espaces l"un de l"autre par une traverse rigide (28) placee dans la partie siege, a proximite du dossier. L"ensemble siege-dossier est relie a un cadre d"une chaise en quatre points seulement suivant une disposition de "berceau", au moyen d"une paire de crochets (33) partant de l"arriere des sommets des supports relativement rigides, recus dans des fentes (34) du cadre de la chaise, et par des connexions boulonnees (36, 60) des organes de support relativement rigides dans la partie avant du siege sur le cadre de la chaise. L"ensemble siege-dossier et en particulier les organes du cadre relativement rigide, sont precontraints lorsque la partie siege est connectee au cadre de la chaise. Un materiau de recouvrement, qui peut etre amovible, est dispose sur l"ensemble siege-dossier. Une simple structure d"un cadre de chaise est utilisee, avec une configuration en forme de X a la partie inferieure et quatre pattes verticales. Cette structure peut etre realisee avec deux elements tubulaires, formant chacun une patte avant et une patte arriere, ainsi qu"une partie coudee d"attache, les parties etant reliees au centre.
