Definitions

  • the invention relates to a seat and a chair.
  • air-filled hemispheres are known, which are placed on an existing seat of a chair and should provide a dynamic fit. Due to the hemispherical seat, the sitting position is too unstable for longer sitting.
  • the invention has for its object to provide a seat and a chair, which allow or cause a particularly comfortable and back-friendly seats.
  • the seat according to the invention for a chair in particular an office chair, comprises a shaped body which is filled or filled with a gas.
  • the molded body is formed of a flexible material and is deformable under load by a person sitting thereon in a predeterminable manner. It has a dimensional stability, such that the shaped body returns both when the load is returned to its original shape as well as a predeterminable deformation under load assumes such that a stable seating position can be produced.
  • the chair according to the invention has a seat according to the invention.
  • One aspect of the invention can be seen to make the seat of a chair, so the element on which a person sits as a filled with a gas, in particular air, molded body and thus deformable element.
  • a gas in particular air, molded body and thus deformable element.
  • a stable compared to a seat ball seats should be guaranteed. This is done according to the invention by the shape and / or the material of the molding.
  • the material of the molded body has a certain dimensional stability, which allows a moving sitting, but at the same time provides a stable seating position.
  • the molded article is preferably yielding and at the same time supporting.
  • the shaped body is provided for providing a saddle-like sitting with at least one front saddle nose and lateral, obliquely downwardly curved leg support surfaces.
  • the molding has a total of a saddle shape.
  • the saddle-shaped, filled with gas molding of a flexible material causes on the one hand by the volume of air a moving or moving seats. The user must therefore always perform certain compensatory movements, whereby a rigid posture is avoided.
  • a spread leg position is enforced by the saddle shape, which causes a certain sitting stability and also increases the opening angle between the upper body and thigh.
  • the volume of air surrounded by the shaped body contributes to a uniform pressure distribution on the body of the user. Overall, the discs a particularly good relieving sitting causes by the combination of a saddle-like sitting and an air or gas-filled molding.
  • the shaped body has a seat surface which has a convex curvature in a transverse direction and a concave curvature in a longitudinal direction.
  • the transversely convex curvature provides some instability of the transversal seating position so that the user makes small compensatory movements that mobilize the intervertebral discs.
  • the longitudinally concave curvature stabilizes the user in the longitudinal direction, thus preventing slipping, for example forward.
  • the seat is generally rising toward the rear; the back of the seat is thus higher than the front, with preferably a deepest point may exist between the front and rear ends. The overall rising seat causes a tilting of the upper body to relieve the intervertebral discs.
  • the seat has a trough in the longitudinal direction, in particular in a center plane, wherein the rearward increase is greater than the rise to the front.
  • the highest point of the seat is preferably formed by a rear, transversely central area.
  • the second highest point is preferably in a front, in the transverse direction central area.
  • the convex curvature preferably extends from a left outer side to a right outer side of the shaped body.
  • the concave curvature preferably extends from a front side to a rear side of the shaped body.
  • the shaped body has a curved underside.
  • the curved underside allows a targeted adjustment of the thickness of the molding, so that the air volume can be reduced compared to a spherical molding. In this way, a more stable and / or more comfortable seating position can be achieved overall.
  • the shaped body has a curved underside whose curvature corresponds approximately to the curvature of the seat. It is particularly preferred that the shaped body has a lower side which has a concave curvature in a transverse direction and a convex curvature in a longitudinal direction.
  • the underside and the upper side of the foam body in each case relate to the corresponding outer sides of the molded body.
  • the shaped body has a curved top and a curved bottom, which are substantially congruent.
  • the shaped body has an at least substantially constant thickness.
  • the shaped body has a constant thickness along its width (extension between the left and right ends) and / or its depth (extension from front to back).
  • the thickness relates in particular to the extent of the shaped body transversely to its width or depth, or even transversely to its seat.
  • the thickness of the shaped body can also be referred to as height.
  • the shaped body has an upper wall, a bottom wall and a circumferential annular wall, which together surround or border a gas volume.
  • the circumferential annular wall is preferably curved in some areas inwards, that is, has a concave curvature.
  • the annular wall has two regions with a concave curvature, which are located in lateral regions of the molded body (left and right). The concavely curved areas of the ring wall allow a comfortable leg position of the user on the seat.
  • the shaped body is preferably formed of an elastic material, for example rubber.
  • the elastic molded body on the one hand offers the possibility of deformation and on the other hand is dimensionally stable, such that it returns to its basic shape or original shape after the return of a load.
  • the shaped body is dimensionally stable, such that it has a predetermined basic shape in an unloaded state and returns to the basic shape after the return of a load.
  • a valve for introducing and / or discharging gas from the shaped body is preferably provided.
  • the valve allows a variable filling of the molding with the gas, so that a variable stiffness of the molding can be adjusted.
  • the filling of the molding with gas (air) allows an adjustment of the movement or the deformability of the molding. The flexibility of the molding can thus be adjusted via a variable pressure in the molding.
  • the molded body preferably has in the region of its underside a connection point or connection device for connecting a chair frame.
  • the connection device or connection point is preferably located in a central region of the underside of the molding.
  • the chair comprises a central pillar which supports the seat and, in particular exclusively, supports it centrally.
  • the column can be designed as a lifting column for a height adjustment.
  • the seat is supported only in an inner region and levitating in an outer region.
  • the dimensional stability of the molded body ensures that the seat retains its predetermined basic shape despite only a central support, especially in the unloaded condition. Due to the lack of outside support, the molded body adapts very well to a user, so that a particularly comfortable sitting is possible.
  • the chair according to the invention comprises a seat which is formed by the shaped body according to the invention.
  • a central support is provided, which centrally supports the molded body on a lower side (bottom wall).
  • the central support preferably has at a lower end a foot part, which may comprise rollers.
  • the foot can be designed, for example, star-shaped.
  • the seat formed by the molded body is supported in particular exclusively in an inner (central) region of its underside by the support or the chair frame.
  • a seat 10 according to the invention comprises a shaped body 12, which is integrally formed as a hollow filling body made of a flexible, in particular elastic material.
  • the seat 10 comprises a gas volume 44, which is bounded by the shaped body 12.
  • the shaped body 12 thus forms a gas-filled casing, in particular rubber casing.
  • a valve 42 is formed through which gas can be introduced into the molded body 12 and discharged.
  • the material of the molded body 12 is gas-tight.
  • the molded body 12 has an overall saddle shape and consists of a top wall 14 whose outer side forms a seat surface (top) 20, a bottom wall 16 (bottom wall) and an annular wall 18 extending between the top wall 14 and the bottom wall 16 extends.
  • An outer surface of the bottom wall 16 forms an underside 30 of the molded body 12.
  • Both the seat 20 and the bottom 30 are curved.
  • the seat 20 and the bottom 30 are approximately the same shape, so that the molded body 12 along its longitudinal direction 2 and its transverse direction 4 has a substantially constant thickness 6, which is defined by the height of the annular wall 18 substantially.
  • the filled with gas, in particular air, shaped body 12 is deformable on the one hand and on the other hand has a dimensional stability, which allows a user to assume a largely stable seating position, but the predeterminable, must compensate for comparatively small deformation so that it sits "dynamically". Due to the shape and / or the material of the molded body 12, the deformation can be pre-determined be limited, for example, to an impressions of 5 cm.
  • the seat surface 20 has, at least in regions, in the longitudinal direction 2 of the molded body 12 a concave curvature, as in Fig. 4 shown. In the transverse direction 4 of the molded body 12, the seat surface 20, at least in regions, a convex curvature, as in Fig. 5 shown. On the outer sides of the convex curvature in each case a leg support surface 22 is formed, which drops down to the outer sides.
  • a saddle nose 40 is formed, which extends in the illustrated embodiment, starting from a central region of the shaped body 12 forward and upward.
  • a rear portion of the seat 20 is formed as a rising portion 24 and in particular higher than the saddle nose 40th
  • connection device or a connection portion 32 for connecting a support 52 of a stool or chair available.
  • FIGS. 6 and 7 show a chair 50 according to the invention with a chair frame 51, which has a central support 52.
  • the support 52 is connected to the connection region 32 on the underside of the seat 10, so that the gas-filled seat 10 is supported exclusively centrally from below.
  • the chair 50 further includes a backrest 54 and armrests 56 fixedly connected to the chair frame 51.
  • rollers 58 are mounted so that the chair can roll on the floor.
  • the chair 50 allows a saddle-like sitting due to the gas-filled, saddle-shaped seat 10, wherein a user also has the opportunity to lean against and / or his arms to support.
  • the comfort properties of a conventional back chair are combined with those of a saddle-like stool.
