Definitions

  • the invention relates to a seat for a chair as indicated in the introduction to claim 1.
  • the invention is preferably intended for chairs of the kind which are used many hours each day such as working chairs, office chairs- motor vehicle seats etc, special chairs for various groups of patients suffering from various pains in the pelvic region but may of course also be used for rest chairs of various types.
  • the seat is particularly suitable for improving ergonomics in connection with office and working chairs.
  • the seat according to the invention is designed as disclosed in the characterising part of claim 2 , there is moreover obtained a relief of the lower part of the back in that the coccyx will rest on the softer material. There is thus obtained a further improvement of the properties of the seat since the spine is not adversely loaded - the muscles are rather allowed to work dynamically so that the segments in the entire spine will work within their natural area of motion.
  • the mere use of a fixed seat according to the invention thus offers the same advantages as are otherwise only obtained by the known chairs where the seat can be tilted forward. If the seat according to the invention is used on a tilting chair, all the advantages of the tilting seat are increased because the pressure distribution on the body becomes absolutely ideal.
  • the seat according to the invention is preferably designed as disclosed in the characterising part of claim 3 in that the central soft area may thus be freely ventilated.
  • the seat according to the invention is designed as disclosed in the characterising part of claim 4. There is thus obtained optimum ventilation without reducing the advantages mentioned in claims 1 and 2.
  • the result is' therefore an ideal combination in that the central part is ventilated optimally so that the user will not have the natural microclimate in the seat region ruined by too great secretion of sweat when for example sitting on an office chair all day.
  • the chair has moreover proved to be very comfortable and relieving to sit on if the user is for example suffering from menstrual pains or has descended pelvis or other sufferings or diseases.
  • the seat according to the invention is preferably designed as disclosed in the characterising part of claim 5. It is thus possible in a simple manner to achieve the desired effects and there is obtained a seat which is very simple to produce.
  • the seat according to the invention is preferably designed as further defined in the characterising part of claim 6. This material is compressed by the body weight to a suitable hardness in that it
  • the seat according to the invention is preferably designed as disclosed in the characterising part of claim 7.
  • the drop-shaped design extending from the rear edge of the seat towards its centre where the soft part is of • almost circular shape has turned out to give the desired properties and advantages, and the size of the central soft area as disclosed in the claim has turned out to suit the majority of the users.
  • Fig. 1 shows a plane section of a seat in the direction I-I in Fig. 2, and
  • Fig. 2 shows a vertical section on a larger scale of the seat in Fig. 1 in the direction II-II.
  • the seat 1 consists of a seat bottom 6 which is for example manufactured of formed plywood or another suitable material. On the seat bottom 6 there is arranged and secured a cushion 2 with a central part 3 having a rearwardly extenting part 7. The seat cushion or the padding is covered by a cover 5 of fabric or another non-airtight material.
  • a drop-shaped central part 3 Centrally in the seat cushion 2 there is arranged a drop-shaped central part 3 with ventilating holes or channels 4 extending all the way through the central part and out through the seat bottom 6.
  • the central area 3 extends all the way to the rear edge of the chair seat so that there is formed a channel-like area 7.
  • the soft central part 3 can therefore be ventilated through the rearwardly extending area 7 as well as through the ventilating holes 4 .
  • the seat cushion 2 is for example made of polyurethane foam with a density of 48.0 kg/m 3 and a hardness index of 200N (N:newton).
  • the drop-shaped area forming the central soft part 3 and 7 is for example made of polyurethane foam with a density of 36.0 kg/m 3 and with a hardness index of 150N.
  • the density of the materials are measured according to ISO 1855 and the hardness according to ISO 2439, procedure A by 40% compression. Both materials are fire retarded so that they comply with the rules in California Bulletin No. 117, sec. A+D.
  • the seat structure according to the invention may be used for almost any kind of chair in that the soft area 3 is designed in drop-shape as shown in the drawing and with a width T of the central part of about 10-20 cm, preferably about 15 cm. It is obvious to a person skilled in the art that the physical sizes as well as the relative sizes of the areas 2 and 3 may be changed and adapted to each other both with a view to which chair the seat is to be used for and with a view to the person who is to use the chair. It is for example possible to imagine that chair seats in the same size are designed with different sizes of the drop-shaped area.

Abstract

Le siège de chaise ci-décrit comprend un coussin de chaise (2) muni d'une partie centrale (3) traversée par des trous de ventilation (4) et une partie s'étendant vers l'arrière (7). Ledit siège est recouvert par une housse (5). La partie centrale (3, 7) en forme de goutte est fabriquée dans un matériau plus mou que le matériau du coussin (2) lui-même. Il en résulte que la charge s'exerçant sur le postérieur et la région du bassin de l'utilisateur se répartit de telle sorte que la partie centrale du siège se trouve relevée par rapport à la charge s'exerçant sur les cuisses et les fesses de l'utilisateur. Au même moment, la partie centrale (3) qui est molle est conçue de telle sorte que le coccyx repose sur ladite partie, évitant ainsi que des charges ayant une influence défavorable ne s'exercent sur la colonne vertébrale.
