摘要:
Ce dispositif est remarquable en ce qu'il comprend une bande (3) réalisée en matière plastique solidarisée sur la ou les bordures extérieures de la toile (1), ladite bande présentant au moins une patte (3a) profilée obtenue par moulage et monobloc avec la bande, ladite patte présentant une forme en berceau d'appui pour être introduit contre la paroi en regard du longeron de la structure portante, et dans les intervalles formés entre ledit longeron et un profilé solidarisé au dit longeron, et en ce que la zone de jonction entre la bande et la patte constitue une zone de contre appui susceptible de permettre l'appui d'une partie ondulée du profilé en autorisant ainsi un verrouillage en position de la patte par rapport au longeron en regard.

Sitzschale, Sitz oder Liege, deren Stützfläche (14) von gekrümmt verlaufenden Formteilen (1) gehalten wird und dadurch gekennzeichnet sind dass diese unterteilt sind und an den Teilungsübergangsstellen Dreh- und/oder Schwenklager aufweisen, so, dass das Ende eines Formteils die Richtung des nächsten Formteils bestimmt und durch gegensinniges Verdrehen aneinandergereihter Formteile grosse Auslenkungen der Stützfläche bei kleinem Schwenkbereich der Formteile oder eine Verlängerung des Wirkbereichs der Formteile, durch ein Dreh/Schwenklager das ein Fluchten eines folgenden Elements gewährleistet.
摘要:
A chair, armchair, comprising a fabric component constituted by two rod-like elements (12,13) made of plastics with a C-shaped cross-section, each of which has a wing that is larger than an opposite wing and has a thickness that allows it to be fixed to the edge of an element (17) made of fabric by stitched seams (18), the elements having a C-shaped cross-section being assembled by interlocking with opposite edges of a corresponding structural element to be covered of the chair, armchair, tensioning the element made of fabric.
摘要:
An attachment structure for a load bearing fabric. The attachment structure includes interfitted inner and outer rings. The outer ring includes a fabric leg 74 carrying a load bearing fabric. The inner ring defines a channel receiving the fabric leg 74. The inner ring and outer ring are configured to stretch the fabric upon insertion of the fabric leg 74 into the channel. The present invention also provides a method for securing a load bearing fabric to a support structure, generally including the steps of (a) providing an outer ring having fabric leg 74, (b) attaching a section of load bearing fabric to the fabric leg 74, (c) providing an inner ring having a channel adapted to receive the leg of the outer ring and (d) installing the outer ring to the inner ring by inserting the leg into the channel, the insertion forcing the fabric down into the channel and stretching the fabric to the desired tension.

A seat suspension membrane (34) is provided which consists substantially of a biaxially oriented film of a polyurethane thermoplastic elastomer composition, which composition is characterized by substantially linear polymer molecules containing alternate rigid segments of diisocyanate short chain diol addition reaction products and flexible segments of relatively high molecular weight polyether diol or polyester diol segments and which is produced from a relatively soft film composition.

A composite foam base air cell module cushion (10) having a water resistant skin (13), a contoured foam base (11) designed to relieve pressure on the trochanters and the ischia and an air cell module (12) having two pairs of air cells (41), each partially filled and positioned in a chamber (30) beneath the rear of the base (11). The skin (13) is of two layer constructions with a two-way stretch outer layer (14) and a water impervious inner layer (15). The bottom (29) of the base (11) is covered with a water impervious sheet (55) and the edges are secured to the edges of the top skin covering (13). The air cell cushion (10) is made by placing the preformed top into molds smaller in depth than the air cells (41) to partially collapse the air cells (41) before a base (40) is applied to the top to close the open ends of the air cells (41) and trap air therein.

摘要:
There is described a tiltable chair including a base member, a seat, a back and a linkage assembly adapted to allow the seat and back to tilt downwardly and rearwardly and to allow pivotal movement of the seat about a pivot axis in substantial alignment with the hIp joints of a user. Other aspects of the invention are to provide a vertically adjustable column for supporting the seat of the chair, a support assembly including a frame member having a central opening therethrough and a receptacle formed around the perimeter thereof, a carrier member adapted to fit inside the receptacle, a membrane of elastic material covering the central opening, and a pair of armrests adapted to be mounted to the chair to allow pivotal movement thereof.

There is described a tiltable chair including a base member, a seat, a back and a linkage assembly adapted to allow the seat and back to tilt downwardly and rearwardly and to allow pivotal movement of the seat about a pivot axis in substantial alignment with the hip joints of a user. Other aspects of the invention are to provide a vertically adjustable column for supporting the seat of the chair, a support assembly including a frame member having a central opening therethrough and a receptacle formed around the perimeter thereof, a carrier member adapted to fit inside the receptacle, a membrane of elastic material covering the central opening, and a pair of armrests adapted to be mounted to the chair to allow pivotal movement thereof.
