Definitions

  • the present invention relates to a mobile seat pad for placement on an existing seat.
  • the seat pad is intended to reduce stress on the back during sitting, for example in back pain.
  • Back pain is one of the most common clinical pictures of modern society. Since most people today spend several hours a day sedentary, it is extremely important in controlling or preventing back pain to ensure that the load on the back while sitting is kept as low as possible.
  • a back-friendly office chair is known, for example, from DE 202010006149U1.
  • the seat is mounted on a single rolling element on a plate.
  • the rolling element is in this case formed as part of a cylinder jacket surface, which is fixed with a central bore on the plate.
  • DE 1020060368 6A1 discloses an improved office chair in which a rolling element in the form of a part of a cylinder jacket surface is fixed to the plate by two holes, the two holes being arranged along an axis transverse to the axis about which the Seat of the office chair is tiltable. As a result, a rotational movement of the seat is prevented.
  • a disadvantage of the approaches described above for a back-friendly sitting is, above all, that in each case a completely new, improved office chair is specified.
  • a completely new office chair would have to be purchased per person.
  • high costs are incurred, for example, for companies.
  • the back will also continue to be unnecessarily burdened.
  • the weight of the office chair is relatively high due to the formation of the rolling element as part of a cylinder jacket surface, for example made of metal. This reduces the mobility of the office chair and increases the material cost of making the office chair.
  • Seat covers are known from DE202007009234U1 and DE202010014627U1, which can be placed on existing chairs and chairs. These known seat pads allow a tilting movement both in the seat direction (direction along the thighs) and across it. This Kippièresdorfkeit in two directions is perceived by many users as uncomfortable.
  • the mobile seat cushion according to the invention has a flat support, in particular in the form of a support plate or a support frame, on which a plurality of Ab- roller skids with at least one fixing element is fixed.
  • the seat cushion has at least one carrier element, which carries the seat element and is connected to the plurality of Abrollkufen. If a plurality of carrier elements is used, then each carrier element is connected in each case to a rolling skid.
  • the Abrollkufen are fixed to the flat support such that the movement of the seat member is limited to a tilting movement on the Abrollkufen to only a defined axis. A rotational movement of the seat element is thus impossible. Since the seat cushion is mobile, it can easily be placed on existing office chairs.
  • the seat cushion can be placed on other seats such as car seats, so that the back-friendly use of the seat cushion is not limited to the workplace or a single office chair. Due to the configuration of the rolling element as a plurality of Abrollkufen instead of part of a solid cylinder surface not only material costs in the manufacture of the seat cushion, but also the weight of the finished seat cushion can be reduced, so that the mobile seat cushion by a person very easy from a chair can be worn in another chair.
  • the one defined axis about which the seat surface is tiltable transverse to the seat direction.
  • the Abrollkufen are connected by means of spring-loaded screws with the flat support. In this way, the tilting movement of the seat member is ensured in the sitting direction in a simple manner.
  • the fixing element is rail-shaped and the Abrollkufen are preferably bolted to the fixing.
  • the seat support in a further embodiment has at least one support element which is connected to the at least one or at least one of the fixing elements and preferably supports the seat element centrally.
  • the support member ends according to a preferred embodiment with a T-piece, the T-bar is slightly bent.
  • the longitudinal beam of the T-piece is rotatably disposed in the remaining support member.
  • the curved shape of the tee which lies between the thighs of a seated person, prevents the ends of the bent tee from rubbing against the thighs.
  • the rotatable arrangement of the T-piece with the overlying seat cover additionally prevents the T-piece from rubbing against the thighs.
  • the seat element consists of a seat plane spanned by the at least one carrier element or the carrier elements.
  • the carrier element has two clamping struts arranged parallel to one another, which run in the direction of the thighs of a seated person.
  • these two clamping struts are connected to the rear side of the seat cushion with a connecting strut. As a result, the stability and comfort are increased.
  • the seat cover By turning the seat cover on the connecting strut and by attaching the lower, folded tension part of the seat cover to the tee or the support element, the seat cover can be clamped in a simple manner in the longitudinal direction.
  • this may be provided with an outer envelope preferably made of textile material or leather, which forms the surface of the seat cushion.
  • This enclosure is preferably fastened with Velcro fasteners on the seat element.
  • the seat cushion is adjustable in width. This can be achieved in a simple manner by a longer connecting strut and by a fixing element with intermediate piece. Further features and advantages of the invention will become apparent from the following description of an exemplary embodiment of the invention with reference to FIGS. It shows:
  • FIG. 1 is a plan view of a first embodiment with removed seat element in the form of a tarpaulin and a continuous support plate,
