Definitions

  • Zugel Attorney-Kurt Kelman ABSTRACT A back support comprising; carrier means adapted to be affixed to the back supporting face of a back rest of a seat or chair; a back supporting bolster; means for releasably interconnecting said bolster to said means to enable same to be placed in any one of a number of adjacent positions; such bolster forming, with the carrier means and the back rest, a cradle into which a portion ofthe back ofa person may snugly lie.
  • One object of this invention is to provide a support for positioning on. or adjacent, the back rest of a seat or chair which provides sufficient support for at least the lumbar region of a seated person's back to minimize such fatigue.
  • a back support comprising carrier means adapted to be affixed to the back supporting face of a back 'rest of a seat or chair; a pair of back supporting bolsters; means for releasably interconnecting said bolsters to said means to enable same to be placed in anyone of a number of adjacent positions; such bolsters forming, with the carrier means and theback rest, a cradle into which a portion of the back ofa person may snugly lie.
  • An intermediary member is provided to which said carrier means is secured and such intermediary member may be releasably secured to the seat.
  • the intermediary member would normally comprise a rela tively thin sheet ofmaterial.
  • Such material may either be flexible or alternatively it may be substantially rigid and may be preshaped substantially to conform with the contour of a portion ofthe back ofa person for whom the support is designed.
  • any means may be provided for releasably interconnecting said intermediary member and the seat such as, for example, a plurality of straps or alternatively at least one length of a malleable material which may be deformed and shaped to provide a hooklike extension which passes over the back rest of the seat.
  • said means for releasably interconnecting the bolsters to the carrier means may comprise a hook-and-pile fabric fastening material of the type manufactured and sold under the Trade Mark VELCRO.
  • Each such bolster carries a component of the VELCRO type material and these bolsters may be interlocked with a mating component of such VELCRO type material which is secured to said intermediary member so that the bolsters may be releasably secured in any one ofa large variety of back supporting positions so that the back rest may be used successively by more than one person.
  • FIG. I is a perspective view of a preferred form of back support adapted to be releasably connected to the back rest of a motor car or like seat;
  • FIG. 2 is an enlarged fragmentary sectional view ofa part of the support of FIG. 1;
  • FIG. 3 is a perspective view similar to FIG. 1 of a second embodiment of support, this second embodiment of support having a rigid portion premoulded to conform substantially with the shape of the back ofa person for whom the support is designed.
  • the back support 1 comprises an intermediary member 2 comprising a pair of superposed padded flexible sheets formed of a material such as leather or a plastics material such as plasticised polyvinylchloride. One or both of such sheets may be perforated to enhance comfort.
  • the upper edge portion of this intermediary element carries a flap 4 also formed from a pair of superposed sheets ofmaterial sewn together about their periphery.
  • a pair of flat bars 5 formed from a malleable material such as mild steel or a metal alloy, so that when these bars are bent the flap provides a hooklike extension which may be placed over the top of the back rest of a seat so that the intermediary member 2 lies adjacent the back supporting surface of a seat back rest.
  • a front face 6 of the intermediary member 2 Sewn to a front face 6 of the intermediary member 2 are two rectangular pads 7, 8 of a material which forms one interlocking component of the fastening material manufactured and sold under the Trade Mark VELCRO, this'material comprising two interlockable material components, the first component carrying a soft pile whilst the other component comprises a dense array of small barbed hooks.
  • a pair of bolsters 9, 10 are provided and each comprises a pad of resilient material which is encased by a sheet of flexible v covering material such as leather or plasticised polyvi nylchloride or any suitable plastics material.
  • Such bolsters 9, it) are shaped so that they have a generally triangulated cross section and with the intermediary member 2 form a cradle for at least the lumbar region of the hack of a person using the support.
  • each of these bolsters 9, 10 carries a sheet 11 of the VELCRO- type material.
  • the bolsters 9, ll) carry the hooked component of the fastening material whilst the pads 7, 8 are formed of the soft pile component.
  • the bolsters 9, it) are thus releasably but firmly secured to the intermediary member 7.. It will be understood that the bolsters 9, 10 may be placed. in any one of a large number of different positions with respect to the intermediary member 2 so that the user of the support may select, after sitting, the position of the bolsters which is most comfortable.
  • the back rest is very similar to the back rest of FIGS. 1 and 2 with the exception of the fact that the intermediary member 2 is not formed as a pair of flexible sheets ofmaterial but is formed by a preshaped substantially rigid sheet of material which may or may not be upholstered and padded.
  • Such rigid member specifically designated 2a is moulded from, for example, glass fibre or a suitable flexible plastics material and carries a plurality of straps 12 by which it may be releasably, but firmly. connected to the back rest of a seat.
  • the bolsters 9, 10 are adjustably secured to the rigid member 2a by means of the VELCRO type material in the same manner already described with reference to FIG. 1.
  • bolsters of varying sizes and shapes may be provided to ensure that a comfortable chair or seat is provided.
  • a back support for attachment to the transverse top edge of a back rest of a seat comprising:
  • a pair of resilient bolsters releasably secured to the sheet member in positions selected so adjacent the lateral sheet member edges that the bolsters and the sheet member constitute a cradle to receive at least the lumbar portion of the back;
  • carrier means releasably holding the bolsters on the sheet member
  • the carrier means being constituted by a hook-and-pile fabric fastening material, one of the components of the fastening material being affixed to the sheet member and the mating fastening material component being affixed to the bolsters.
  • the means for releasably securing the sheet member to the back rest comprises at least one length of a malleable strip material bendable into hook shape to fit over the back rest and thus adjustably to suspend the sheet member on the back rest.
