  • a footrest attachment means in this embodiment provided by a length of elasticized webbing 30 sewed or otherwise fastened at its ends to front corners of the footrest 16 so as to form a loop 32 extending from the front end of the footrest.
  • the child seat 10 can be accommodated in a typical adult passenger seat 34 in an airliner, in the illustrated case an adult passenger seat in the economy class cabin of the airliner.
  • the backrest 12 rests upright against the backrest 34.1 of the passenger seat and the seat 14 locates on the seat 34.2 of the passenger seat, with the extended side regions 14.1.1 folded up to upright orientations against the standard, rigid armrests 34.3 of the passenger seat.
  • the loop 32 carried by the footrest 16 is looped over the conventional, folding tray table 36 mounted at the rear of a passenger seat 38 in the seat row immediately in front of the seat 34 in which the seat 10 is accommodated. This is achieved by releasing the tray table, swinging it down at least partially, passing the loop over the table and then folding the tray table up again and stowing it. The loop then passes either around stowed tray table itself or around the supporting structure 40 forming the conventional tray table hinge. In the result, the footrest 16 is slung hammock-style between the seat 14 of the child seat 10 and the tray table 36.
  • a small child 41 can now be placed in the installed child seat.
  • Normal security is established by buckling the conventional seat belt or lap strap 43 associated with passenger seat 34 over the child's abdomen.
  • the components of the conventional seat belt which are typically anchored relative to the sides of the passenger seat, are brought together for buckling to take place, they will cause the extended side regions 14.1.1 of the lower seat part 14.1 to fold over and provide a measure of lateral restraint to the lower part of the seated child's body and will also cushion the child relative to the rigid armrests.
  • lateral restraint is provided to the upper part of the child's body by the side bolsters 12.2 of the backrest.
  • the thickened front regions of the lower and upper parts 14.1 and 14.2 of the seat 14 serve to raise the child's legs, typically in the region of the knee, relative to the waist and to urge the child's body, under gravity, rearwardly into the seat, as shown in Figure 2. This provides a comfortable seated or slightly reclined body position and acts to prevent the child from sliding forward under the buckled seat belt.
  • the footrest 16 is at a high enough elevation for the child's feet to rest on it as shown in Figure 2. This provides comfortable foot support and also contributes greatly to restraining forward movement of the child's body.
  • the density of the foam used to make the cores used in the backrest and seat parts will be such that the backrest 12 and seat 14 can deform resi!iently, i.e. compress, as necessary to accommodate the child's body contours in an extremely comfortable manner.
  • a first step in folding up the seat 10 is to fold the backrest 12 downwardly over the seat 14. As the length of the backrest is greater than that of the seat, the end of the backrest can be folded around the front edge of the seat.
  • the extended side regions 14.1.1 of the seat part 14.1 are now folded up over the sides of the backrest and are anchored in position by engagement of clip components 50 fastened to the front corners of the extended side regions with mating clip components 52 fastened to the rear of the backrest, as shown in Figure 8.
  • the footrest 16 is folded up over the backrest and is anchored in position by engagement between a clip component 54 fastened to the front edge of the footrest and a mating clip component 56 fixed to the rear of the backrest.
  • the various clip components 50, 52, 54 and 56 are fastened in position by means of short, flexible straps sewn or otherwise fixed to the extended side regions, the footrest and the rear of the backrest.
  • two elastictzed webbing straps 60 are sewn or otherwise fixed to the front corners of the footrest to form stretchab!e loops 62.
  • the loops can be stretched and passed around the folded structure to provide two generally parallel carrying straps 64.
  • the folded seat 10 can then be carried manually by grasping the straps or, alternatively, the straps can be located over the shoulders of a wearer so that the folded seat can be carried in the manner of a backpack.
  • the seat 10 is extremely light and easily transportable in either manner. In particular, it is believed that the seat will be light enough to be carried comfortably by a small child 41 who is old enough to walk competently.
  • FIGs 11 to 18 illustrate a second, currently preferred, embodiment of the invention.
  • This embodiment has many similarities to the embodiment described above, and corresponding components are designated by the same reference numerals prefixed by the numeral "1".
  • the seat 114 of the seat structure is provided by a single, wedge-shaped body. This may again include an inner core of a flexible, resiliently compressible foam material housed in an outer cover of suitable material.
  • the rear end of the seat 114 in this embodiment is attached to the lower edge of the backrest, in a hinged or pivotal manner, via an intermediate panel 170 of flexible material.
  • the backrest 112 of the second embodiment is generally similar to the backrest 12 of the first embodiment.
  • One difference is that it carries side flaps 172 which are sewn to opposite sides of the lower end region 173 of the backrest so as to extend from the backrest.
  • Each of these flaps has an inner, generally rectangular core of flexible, resiliently compressible foam material housed in an outer cover.
  • the side flaps 172 can be folded forwardly so as to provide lateral restraint to the body of a child seated in the seat 110 and also so as to provide side cushioning relative to the rigid armrests of the airliner.
  • the two webbing straps of the conventional airliner seat belt or lap strap (not shown in Figures 11 to 18) are passed upwardly on either side between the side flaps 172 and the seat 1 14 and are buckled together in the normal way over the abdomen of a child on the seat.
  • the loop 132 at the front or leading end of the footrest 116 is provided by two flexible straps 130.
  • the ends of the straps can be tied together to form the loop 132.
  • the ends of the straps could carry clips which are clipped together, or other mating components that can be attached to one another, to form the required loop.
  • the loop is, as in the first embodiment, used to attach the footrest relative to the tray table in front so that the footrest is slung between the seat 114 and the tray table to provide support for the feet of the child seated on the seat 110.
  • FIG. 13 Another difference between the second embodiment and the first embodtment is that shoulder straps 174 are fitted to the rear surface of the backrest, as shown particularly clearly in Figure 18.
  • the second embodiment can be folded up extremely compactly.
  • a first step in the folding procedure is to fold the footrest 116 back over the seat 114.
  • the seat 1 14 is folded over relative to a lower part of the backrest 112 ( Figure 14), and the upper end of the backrest 112 is folded over the seat and is secured in place by clip engagement of mating clips 176 carried by straps 178.
  • a first one of the side flaps 172 is then folded over the seat 114, whereafter the other, second side flap is folded over the first side flap. Clips carried by the respective side flaps are then engaged with one another to secure the side flaps in position ( Figure 15).
  • the airliner seat is folded to a compact form with the shoulder straps 174 enabling the folded seat to be carried in the manner of a backpack.
  • the folded seat has a size less than that stipulated for cabin baggage and so can be placed in an overhead luggage bin of the airliner when not in use.
  • the recessed, central region 1 12.3 of the backrest 1 12, between the bolsters 112.2, has a width approximately the same as the width of the seat 114. Accordingly, when the backrest is folded over the seat during the folding procedure, the seat is accommodated between the bolsters. This contributes to the compactness of the folded seat.
  • a feature of the second embodiment is a storage pocket 180 ( Figures 14 and 17) formed by a rectangular expanse of flexible material, possibly a mesh material, sewn to the underside of the seat 14 along three sides but open along a fourth side 182. Access to the pocket, which is useful for storing an item such as a book, is through the open side.
  • the thickened side bolsters 112.2 of the backrest of the second embodiment are only present in an upper part of the backrest to provide lateral restraint to the upper part, for example the shoulders, of the child's body.
  • the second embodiment may also be provided with other externally accessible pockets (not shown) for accommodating other articles, for example a drinking bottle.

Abstract

La présente invention concerne un siège d'avion pour jeune enfant (10, 110) qui répond aux problèmes de confort et de sécurité. Le siège comporte une structure de siège pliable qui fournit un dossier souple, compressible de manière élastique (12, 112) et un siège souple, compressible de manière élastique (14, 114) fixé de façon pivotante par rapport au dossier pour pouvoir s'étendre vers l'avant à partir du dossier lors de l'utilisation. La structure du siège est d'une taille destinée à loger le siège dans un siège d'avion pour passager adulte (34). L'invention concerne également un repose-pieds flexible 16, 116) qui est fixé à la structure du siège de manière à pouvoir s'étendre vers l'avant depuis celui-ci lors de l'utilisation, et également un moyen de fixation de repose-pieds (30, 130) au moyen duquel le repose-pieds peut être fixé par rapport à la structure de l'avion, typiquement une tablette (36) qui est espacée du siège passager et située devant celui-ci. Le repose-pied est donc suspendu entre la structure du siège et la structure de l'avion dans une position surélevée pour soutenir les pieds d'un enfant assis sur la structure du siège. Outre l'amélioration du confort d'un enfant assis, le repose-pieds empêche l'enfant de glisser en l'avant sous la ceinture de sécurité obligatoire du siège du passager de l'avion.
