Definitions
- the invention relates to a piece of furniture with a frame-like frame and foot elements arranged thereon on a substantially flat surface Floor space can be placed, the seating furniture still on frame-like frame arranged, adjusted, adjustable seat element with a seat intended for a user and one in the rear Area of the seat element arranged backrest, wherein the Seat surface is inclined to the floor surface and a seat inclination angle includes, and wherein means for longitudinal displacement of the seat member on frame-like frame arranged and designed such that for change the effective seat a longitudinal shift compared to Backrest without changing the seat angle is done according to the generic term of claim 1.
- the object of the present invention is to provide seating create that for a variety of users of different physiques adjust optimally at seat height and effective seat surface (seat depth) leaves.
- a key concept of the present invention is that the change the effective seat is in a seat depth adjustment direction E, towards the floor surface by a seat depth adjustment angle ⁇ in the direction is sloping towards the backrest, the seat depth adjustment angle ⁇ is greater than the seat angle ⁇ .
- This technical Design is based on the consideration that in relation to the Average taller or smaller users not only the seat height (lower leg length), but also the effective seat surface or seat depth the larger or smaller thigh length is to be adjusted. According to the invention takes place when the seat element is shifted in a predetermined linear relationship a change in both the seat height and the effective seat surface (seat depth).
- the seat depth adjustment angle is between 16 and 21 °, the optimal angle also depending on the inclination the seat surface depends on the floor surface.
- a seat depth adjustment angle ⁇ between 16 and 21 ° an orthopedically appropriate adjustment of the seat element to the body size of the respective user is possible.
- the Longitudinal displacement of the seat element separately from any other adjustment options the seating, such as in particular the pivoting of the Backrest. If the backrest can be swiveled over a Swivel mechanism is provided, this swivel mechanism is preferred mechanically by the means for longitudinal displacement of the seat element decoupled.
- the gap compensation means are by appropriately shaped and at least in their area facing the gap elastically formed gap compensation padding.
- the upholstery is so flexible in the area of the seat element that a Longitudinal adjustment of the seat element can be compensated.
- the backrest is in storage kept longitudinally displaceable and is supported on the seat, so that when adjusting the length of the seat element, the backrest due to its Weight always strives to close any gap.
- the seat element must be designed so that it can be changed evenly the seat height by 5 to 50 mm, preferably 10 to 40 mm, in particular by about 25 mm with simultaneous enlargement or reduction of the for an effective seat is achieved.
- a seating element 15 for a piece of seating furniture is shown schematically in a side view shown.
- the seat element is arranged in a frame-like frame 11 and compared to this frame-like frame via means 16, 17 for Longitudinal displacement of the seat element - in the present embodiment straight - slidably mounted.
- the means of longitudinal displacement comprise guide rails arranged on the side of the frame-like frame 11 16 and corresponding (or running in the guide rails) Rollers 17 which are attached to the seat member 15.
- Seat element 15 at four points longitudinally displaceable relative to the frame-like frame mounted so that two guide rails 16 are spaced apart are provided on both sides of the seat element 15.
- the seat element 15 comprises a seat surface 22 which is opposite to one another by a floor surface 13 (see FIG. 5) defined horizontal lines by a seat inclination angle ⁇ Backrest is sloping.
- the Backrest 14 is in the rear area above the seat surface 22 of the seat element 15 arranged, that is, the seat member 15 may be due its longitudinal adjustability under the backrest over a certain adjustment range move back and forth in a seat depth adjustment direction E.
- the effective seat surface can be changed, for example here between 430 mm and 550 mm.
- the embodiment shown here has the backrest 14 with gap compensation means 19, which is defined here by a gap compensation padding 20 become.
- the gap compensation padding 20 is above the required Area so flexible that it adapts to the seating element 15 and at gives way to the top of the migrating seat or when the seat 22 is adjusted expands downwards accordingly and the formation of a gap 18 tries to prevent.
- To the rear are seat element 15 and backrest 14 blinded by a cover 27.
- FIGS. 1 and 2 Means 16, 17 for longitudinal displacement of the seat element 15 in more detail explained, in Fig. 3, the guide rails 16 so on the frame-like frame 11 are arranged that a seat depth adjustment angle ⁇ of 21 ° is achieved becomes. In the embodiment illustrated with reference to FIG. 4, the Guide rails 16 arranged on the frame-like frame such that a Seat depth adjustment angle ⁇ of 16 ° is achieved.
- FIG. 5 the overall arrangement of a seat element 15 with the band is Figures 1 to 4 explained embodiment of the means 16, 17 for longitudinal displacement illustrated.
- the setting direction is E inclined by the angle ⁇ with respect to the bottom surface 13, the between an imaginary extension of the guide rails 16 and the bottom surface 13 results.
- the frame-like frame 11 comprises side elements 28, 29 which are in their upper range in the present embodiment simultaneously include armrests 30, 31 and in their lower Area foot elements 12, with which the seating furniture opposite each other the bottom surface 13 supports.
- FIG. 6 the embodiment illustrated in FIG. 5 is one Seat furniture according to the invention shown in a view from behind. Laterally is the seating furniture by the side elements 28, 29 already mentioned limited.
- the backrest 14 is opposite the frame-like frame 11 Height-adjustable via bearings 25, 26 so that the backrest 14 solely due to their gravity to a changed height of the seat surface 22 adapts.
- the seating furniture also includes locking options (not shown) the seat element 15 in a position adapted to the respective user (Seat height / effective seat). You can do this, for example latching mechanisms or gas pressure springs known from the prior art are used.
- the locking devices can also together be formed with a mechanical or electrical drive.
- the longitudinal adjustment could be adjusted using a threaded spindle, the spindle path is dimensioned so that already due to the There is a friction lock.
- the spindle adjustment could be done manually or operated electrically.
