Definitions

  • the invention relates to seating with a frame, a seat cushion, possibly a backrest and an adjustment mechanism for the height of the seat cushion.
  • the invention has for its object a seating To provide which seat height adjustment still has other functions.
  • the Adjustment mechanism an adjustment scissors with two Has scissor arms, the two scissor arms over one Joint are interconnected, the joint the Scissor arms each divided into two arm sections and an arm section of a scissor arm on the seat cushion and one arm section of the other scissor arm on the frame or is also attached to the seat cushion and an arm section or the joint is coupled to an adjustment drive.
  • the scissor arms can also be used instead of the seat cushion a holder or a holder for the seat cushion attack. This has the advantage that the seat cushion is easy to replace.
  • the invention will now be as follows described that the scissor arms engage the seat cushion, the other solution being equivalent.
  • the seat cushion raised or lowered using a pair of adjustment scissors.
  • the adjustable scissors with two scissor arms are for this equipped, which are connected by a joint are. If the scissor arms are adjusted against each other, then can the seat cushion, which with at least one of the upper arm sections connected, raised or be lowered.
  • the adjustment of the adjustment scissors takes place by means of an adjustment drive, which either on Joint or attacks on one of the arm sections and on Supporting the frame of the seating furniture.
  • the adjustment drive can but also attack both arm sections. It can the seating furniture is an armchair, a sofa, a chair or a Be a stool.
  • one Arm section of the two scissor arms namely the two lower arm sections, on a runner or roller on Supports the ground.
  • These two arm sections form the feet of the seating furniture.
  • the one end of the arm section provided role allows easy transport of the Seating and easy adjustment of the Adjusting scissors as they reduce the frictional resistance during the Adjustment process in which the free ends of the lower Arm sections change their distance from each other to a Minimized.
  • the runner allows a limited Unrolling the free end of the other arm section what when adjusting the adjustment scissors is necessary because the inclination of the two adjustment arms changes.
  • the arm section of one scissor arm is preferred pivotally attached to the frame and is an arm section of the other scissor arms can be swiveled and moved on the frame guided.
  • the Adjustable scissors are not a stand but with theirs fixed at the lower end to the frame. The frame sits directly on the floor.
  • This can be the end of the slidably mounted arm section in the desired Positions are brought, whereby not only the desired height of the seat cushion but also a Desired inclination and seat depth can be adjusted.
  • the seating must be designed accordingly, in particular at different seat inclinations the seat cushion in its Level slidably, and with different Seat inclinations must either tilt the frame or that Seat cushion can be pivoted.
  • the rear section of the The seat cushion moves more or less far below the Backrest or emerges from it.
  • the adjustment drive is a tension spring, a gas spring or a motor drive.
  • Tension and gas pressure springs are relatively simple, safe and inexpensive Components. With these drives it is guaranteed that they over the lifespan of the seating furniture without any problems Afford.
  • a motor drive has the essential Advantage that with it the adjustment in both directions can take place, i.e. that the seating furniture can also be used without external Force applied to desired settings can be.
  • the spring is released by means of a locking device e.g. has a setting, in which a Latch is relocatable. With the setting backdrop several rest positions defined, the end positions and may be assigned to several intermediate positions.
  • the lock is on Bowden cable operated, via which e.g. a gas pressure spring is controlled.
  • Adjustment link on the underside of the seat cushion is provided and that to solve the locking Seat cushion can be raised. This is particularly the case with stools This is an advantage because they then do not require an operating lever.
  • the Joint unevenly divides the scissor arms and the short ones Arm sections in front, i.e. arranged facing the seat edge are.
  • the seat height adjustment the inclination of the seat cushion is also adjusted.
  • the seat depth is changed when the height is adjusted.
  • the invention is also in one embodiment characterized in that two free ends of each Arm sections are mounted on two rails.
  • the lower rail on the frame and the upper rail on Seat cushion attached If the adjustment scissors are operated, then the relative positions of the rails change to each other, causing the seat cushion opposite the frame is shifted. This can result in a change in altitude, one Change in inclination and / or in a change of Seat depth result.
  • the backrest can be adjusted in inclination or the backrest can be removable.
  • Prefers is the backrest forward by means of a spring biased.
  • the Reference numeral 10 denotes a piece of seating, which either is designed as an armchair 12 or as a stool 14.
  • the Armchair 12 has a frame 16 on which side cheeks 18 are provided, between which a seat cushion 20 is slidably mounted.
  • the frame 16 has a support 26 on which a rear section 28 of the seat cushion 20 rests.
  • a projection 30 of the backrest 24 or overlapped by a pillow so that the pad 26 is not visible.
  • the rear section be pushed under the projection 30.
  • the backrest 24 also has an upper portion 32 which is over a bearing 34 pivotable on the lower area 22, e.g. by means of a Spring 36 is mounted.
  • the upper area 32 can after be swung out resiliently at the back and assume the position, as for the upper area 32 'with dashed lines is shown.
  • An adjustment scissors 38 is also fixed on the frame 16, which has two scissor arms 40 and 42. These two Scissor arms 40 and 42 are interconnected via a joint 44 connected, this joint 44 the scissor arm 40 in an arm section 46 and an arm section 48 and the Scissor arm 42 into one arm section 50 and one Splits arm section 52.
