Definitions
- the invention relates to a seat, which with a frame-like frame and foot elements arranged thereon on a substantially flat floor surface can be placed, the seating furniture still on the frame-like frame arranged, adjusted, adjustable seat element and one in the rear Area of the seat element arranged back comprises according to the preamble of claim 1.
- the object of the present invention is to provide seating furniture that is ideal for a large number of users of different physiques Seat height and effective seat surface (seat depth) can be adjusted.
- a core concept of the present invention is to provide means for longitudinal displacement to arrange the seat element on the frame-like frame of the seating furniture, which are designed such that the longitudinal displacement of the seat element without change the seat inclination takes place in a seat depth adjustment direction E, this Seat depth adjustment direction E opposite the floor surface in the direction of the backrest is sloping towards an angle ⁇ .
- This technical Design is based on the consideration that in relation to the On average, larger or smaller users not only the seat height (lower leg length), but also the effective seat or seat depth due to the larger or smaller thigh length is to be adjusted. According to the invention takes place at Displacement of the seat element in a predetermined linear relationship Change 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 of the seat depends on the floor area.
- a seat depth adjustment angle ⁇ between 16 and 21 ° is an orthopedic expedient Adaptation of the seating element to the body size of the respective user is possible. With the seat depth automatically adjusted when the seat height is changed becomes an improved thigh support and thus a more uniform Seat pressure distribution achieved.
- the longitudinal displacement takes place the seat element separately from any other setting options the seating, such as in particular the pivoting of the backrest. If one Swiveling of the backrest is provided via a swivel mechanism is, this pivoting mechanism is preferably from the means for longitudinal displacement mechanically decoupled from the seat element.
- the gap compensation means are corresponding shaped and at least in their area facing the gap elastically formed gap compensation padding.
- the upholstery is there in the area of the seat element so flexible 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 at Longitudinal adjustment of the seat element the backrest due to its own weight always strives to close any gap.
- the means for the longitudinal displacement of the Seat elements are to be designed so that a uniform changeability of the Seat height by 5 to 50 mm, preferably 10 to 40 mm, in particular by about 25 mm with simultaneous enlargement or reduction for a user effective seat is achieved.
- a seat element 15 for seating is shown schematically in side view.
- 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 the seat element - straight in the present embodiment - longitudinally displaceable stored.
- the means for longitudinal displacement on the part of frame-like frame 11 arranged guide rails 16 and corresponding (or running in the guide rails) rollers 17 attached to the seat member 15 are.
- the seat element 15 is preferably opposite at four points the frame-like frame mounted longitudinally displaceable, so that two guide rails each 16 spaced on both sides of the seat element 15 is provided are.
- the seat element 15 comprises a seat surface 22 which is opposite one by one Floor surface 13 (see FIG. 5) defined horizontals by a seat inclination angle ⁇ is sloping towards the backrest.
- the longitudinal adjustability of the seat member 15 is also compared to one arranged on the backrest 14 illustrated.
- 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 can due to its longitudinal adjustability under the backrest over a certain adjustment range in a seat depth adjustment direction Move E back and forth.
- Embodiment Since the seat depth adjustment directions E are usually more inclined than the seat surface 22 itself, arises with a completely rigid backrest 14 with the longitudinal adjustment of the seat element 15 variable gap 18.
- Embodiment has the backrest 14 gap compensation means 19, which here be defined by a gap compensation padding 20.
- the gap compensation padding 20 is so flexible over the required range that it can Adjusts seat element 15 and yields when the seat surface moves upwards or at Adjustment of the seat surface 22 expands accordingly and the emergence seeks to prevent a gap 18.
- To the rear are seat elements 15 and Backrest 14 is blinded by a cover 27.
- 3 and 4 are the means already explained with reference to FIGS. 1 and 2 16, 17 for the longitudinal displacement of the seat element 15 explained in more detail, 3, the guide rails 16 are arranged on the frame-like frame 11 are that a seat depth adjustment angle ⁇ of 21 ° is achieved. In the based on 4 illustrated embodiment, the guide rails 16 are frame-like frame arranged such that a seat depth adjustment angle ⁇ of 16 ° is achieved.
- FIG. 5 shows the overall arrangement of a seat element 15 with that based on the figures 1 to 4 illustrated embodiment of the means 16, 17 for longitudinal displacement illustrated.
- the setting direction E is the Angle ⁇ inclined relative to the bottom surface 13, which is 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 region in the present embodiment also include armrests 30, 31 and in its lower area have foot elements 12 with which the seating furniture can be supported against the bottom surface 13.
- FIG. 6 shows the embodiment of an inventive device illustrated with reference to FIG. 5
- Seat furniture shown in a view from behind. Laterally the seating is limited by the side elements 28, 29 already mentioned.
- the Backrest 14 is opposite the frame-like frame 11 via bearings 25, 26 adjustable in height, so that the backrest 14 alone due to its gravity adapts to a changed height of the seat surface 22.
- the seating furniture also includes locking options (not shown) to the Seat element 15 in a position adapted to the respective user (seat height / effective seat).
- locking options for example, according to the status of Technology known locking mechanisms or gas pressure springs are used.
- the locking devices can also be used together with a mechanical or electric drive.
- the longitudinal adjustment Adjust using a threaded spindle, the spindle path being dimensioned in this way is that a lock is already given due to the friction.
- the spindle adjustment could be operated manually or electrically.
