  • the seat and support body 14 facing away from the area Stand 24 is a movable roller system 36 with five rollers connected to the stand 24, so that the seat and support furniture 10 on a base quickly and easily by the user who sits on the seat 16, are moved in the manner of a conventional office chair can.
  • the spring system 34 also includes a stop mechanism 38. At an end of the stand 24 facing away from the seat and support body 14, an end portion 40 of the stop mechanism 38 is arranged, which in Fig. 1 is shown in a retracted state, so that there is no contact with a flat surface and the seat and support furniture 10 can be moved by the movable roller system 36.
  • Fig. 2 shows the seat and support body 24 in its second end position 12b, so that a user can use the support surface 20 for standing still.
  • the support surface 20 is now substantially parallel to a horizontal plane of the seat 16 from Fig. 1 arranged, wherein the seat surface 16 in Fig. 2 substantially parallel to a vertical plane of the support surface 20 Fig. 1 is arranged. It follows that the seat and support body 14 has substantially bypassed a pivot angle of 90 degrees.
  • the first hinge axis 32a of the spring 28 is arranged in a base plane, which is less far from the roller system 36 spaced apart from the horizontal axis 26. Both in Fig.
  • the support surface 20 starting from a starting point, which is arranged substantially vertically above the stand, to an end point in the direction of the roller system 36 a light sloping curvature, which has a comfortable standing sitting result.
  • Fig. 2 is the height-adjustable spring system 34 in an extended state, in this case the Eingelenk 32 is further spaced from the roller system 36 than in Fig. 1 ,
  • the end portion 40 of the stop mechanism 38 is in an extended condition such that the end portion 40 of the stop mechanism 38 is spaced at least as far from the horizontal plane by the horizontal axis 26 as a side of the roller system 36 remote from the horizontal plane the end portion 40 of the stop mechanism 38 is in contact with a floor, thereby preventing movement of the roller system 36, so that the seat and backrest stand firmly when a user leans against the support surface 20 to sit still.
  • the end portion 40 of the stop mechanism 38 is preferably made of a material such as hard rubber, plastic or a similar brakeable material.
  • Fig. 3 shows the seat and support furniture 10 in a front view in the first end position 12a.
  • this first end position 12a of the end portion 40 of the stop mechanism 38 is retracted so that the seat and support furniture 10 can be moved by the roller system 36.
  • Fig. 4 shows the seat and support furniture 10 in a front view in the second end position 12b, wherein the stand 24 has the same height as in Fig. 3 and has not yet been moved by the spring system 34 in a lowered blocking position.
  • the seat and backrest furniture 10 is not yet fully suitable for standing still, since the support surface 20 is too low for a normal sized adult.
  • the seat and support furniture 10 can still be moved by means of the roller system 36 to the preferred position along a floor, in which the seat and support furniture 10 is to be used for standing still. So shows Fig. 4 that at not yet schreibnverêtm stand 24 of the end portion 40 of the stop mechanism 38 is retracted further.
  • Fig. 5 shows the seat and backrest 10 again in a front view in the second end position 12b, in contrast to Fig. 4 the stand 24 has now been adjusted in height by means of the spring system 34, so that a greater distance between the roller system 36 and the support surface 20 has been achieved.
  • the seat and backrest furniture 10 is at a height that the support surface 20 can be used by the user for standing still.
  • the end area 40 of the stop mechanism 38 is extended so that a braking action which blocks the movable roller system is initiated by the contact of the end area 40 of the stop mechanism 38 with a base or floor.
  • Fig. 1 shows that the seat and support body 14 includes a cover 42 which is disposed on a side facing away from the backrest 18 of the seat and support body 14. In this case, a surface of the cover part 42 forms the support surface 20. In Fig. 1 the cover 42 is shown in its retracted position, so that an upper end of the cover 42 does not protrude beyond the rest of the seat and support body 14.
  • Fig. 5 shows the cover 42 in a partially extended position and Fig. 6 shows the cover 42 in its fully extended position.
  • the fully extended cover part 42 an elongated backrest 19 is formed, which is formed in sections from the seat and support body 14 and from the cover 42.
  • the cover part 42 is optionally connected to the seat and support body 14 via a sliding guide or linkage kinematics, the slide guide or linkage kinematics being coupled to the pivotal movement of the seat and support body 14 such that the cover part 32 is extended depending on the end position or retracted.
  • a user can place the seating and support furniture 10 in the in Fig. 1 use for sitting shown first end position 12a.
  • the user can, depending on his wishes, extend the backrest 18 by means of the cover part 42 to the extended backrest 19.
  • a lock which may be arranged, for example, on the spring 28, so that the pivoting movement about the horizontal axis 26 is released.
  • the spring 28 supports the pivoting movement in the second end position 12b or can perform the pivoting about the horizontal axis 26 independently at a correspondingly high selected spring force.
  • the spring system 34 has the properties that it triggers the stop mechanism 38 only at a predefined height by a vertical pressure force.
  • the seat and backrest furniture 10 is not yet in an elevated height-adjusted position in the end position 12b, so that a vertical force exerted on the support surface 20 would not yet lead to an extension of the end area of the stop mechanism 40 , as well as it in Fig. 4 is shown.
  • the spring system 34 adjusts the stand 24 a desired height, which, for example, the height in Fig. 5 equivalent. This height now exceeds the predefined height, from which the spring system 34 can extend the stop mechanism 38.
  • the end portion 40 of the stop mechanism 38 moves as in Fig. 5 shown and thus blocks the movable roller system, whereby the seat and support furniture 10 now provides a secure fit for standing still.
  • the spring system 24, both the Height adjustment ready as well as the property extend the end portion 40 of the stop mechanism 38 from a certain height adjustment.
  • the user can now lock the seat and support furniture 10 in the second end position 12b. By loosening this lock, the seat and support furniture 10 can pivot from the second end position 12b back into the first end position 12a. At this time, the spring 28 damps the pivotal movement, i. the spring 28 is tensioned by manual pivoting. In a next step, the user releases the stop mechanism 38, so that the seat and backrest furniture 10 can be moved again by means of the roller system 36 and adjusts the stand 24 to a desired seat height.
