Definitions

  • the invention relates to seating that is defined by the preamble of claim 1.
  • Such high-class seating furniture are generally provided with a seat plate / backrest adjustment mechanism. It is characteristic that the backrest tilt adjustment is in a rigid proportionality to the backrest tilt adjustment, which is also oriented backwards.
  • Such seating furniture can be found in Swiss Patent No. 629 945, in which a work chair for steplessly changing the seat plate and backrest inclination adjustment is described.
  • the associated adjustment mechanism contains, in addition to a gas pressure spring, a helical compression spring connected in parallel with the latter, the gas pressure spring also fulfilling the function of an actuator in addition to its function as a spring element.
  • the aforementioned spring element parallel connection aims to increase the backrest deflection to the rear against a progressively increasing spring force, the resulting adjustment movement being effected by moving the upper body of the chair user backwards.
  • the movement game can run with free the gas pressure spring can be repeated as required.
  • the gas pressure spring By switching the gas pressure spring as an actuator, the movement play can be stopped in any backrest inclination position, thereby fixing the backrest position.
  • the seating furniture loses an essential comfort component: the automatic adjustment of the backrest inclination if the user wants to lean back for a short time without unblocking the adjustment mechanism.
  • the seating furniture is to offer the possibility of being adaptable to different forms of use quickly and without actuating the adjusting means.
  • the problem to be solved according to the invention on a piece of seating furniture of the type defined at the outset is therefore to improve the function of the backrest by further developing the adjustment mechanism in such a way that the section serving the shoulder support and the support of the middle region of the spine of a user also with a blocked adjustment mechanism and regardless of its blocking position, it can still be pivoted backwards depending on the pressure.
  • a further task is that, based on a basic construction that enables the aforementioned additional backrest pivoting, a To create control and support device for a headrest on the seat, which is pivotally arranged above said backrest section.
  • a third object to be achieved according to the invention relates to the design of an armrest in which the ends of an armrest and a support section are mounted on pivot pins which are attached to points of the seating structure which can be pivoted relative to one another.
  • the object to be achieved according to the invention relates to the design of a single-column support foot for the seating furniture, which can be provided with interchangeable support elements.
  • the seating furniture shown in FIGS. 1 a and 1 b is supported on a single-column support foot 1, which is supported by a height-adjustable support column 2, for example a gas spring, with the seat cap 3.1 of a support arm 3 on a seat support frame, generally designated 4.
  • the support column 2 is expediently surrounded by a casing 5 which is formed, for example, from two telescopically interlocking tubular members. Terms Details of a preferred embodiment of the support foot are made to FIGS. 7, 7a and 7b.
  • the seat support frame 4 contains components of a device, also referred to below as a synchronous adjustment mechanism 6, of which FIGS. shows a controllable gas spring 7 with the piston rod 8 in the extended position.
  • a synchronous adjustment mechanism 6 of which FIGS. shows a controllable gas spring 7 with the piston rod 8 in the extended position.
  • the lever arm 9 of a backrest connection structure 10 is articulated, which is pivotably mounted about a shaft 11.
  • the synchronous adjustment mechanism 6 of which one embodiment is described in CH-PS No. 636 252
  • the lever arm 9 is firmly connected to a support tube 12.
  • An angled upper back part 14, shown in detail in FIG. 2, is also connected to it.
  • a lever (not shown) also present on the seat support frame 4 enables an overflow valve in the gas spring to be actuated, which allows the piston rod 8 of the gas spring 7 to be displaced in the open position, but blocks the piston rod in the closed position.
  • Pushing the piston rod 8 inward (see FIG. 1b) into the gas spring cylinder causes the backrest connection structure 10 to pivot clockwise and thus to move the backrest 14, 16 into the position according to FIG. 1b.
  • this swiveling movement only occurs if, when the overflow valve of the gas spring 7 is open, a swiveling force P is applied at the same time, preferably by leaning back the user of the seating furniture.
  • the ejected gas spring piston rod 8 has the consequence that the slide assembly 13 together with the support arrangement 16 of the frame 17 of the upper part of the backrest connected to it is pushed into an approximately vertical position.
  • the latter contains a shell-shaped rounded component 17 'which is pivotally articulated on the side ends of the support arrangement 16 via a pair of hinges 19 at the bearing point 18.
  • the component 17 ' is expediently a plywood shell, the lower edge of which is supported at 21 on the slide member 20.
  • An actuating spring device 22 has the effect that the backrest frame 1T is always held firmly against the slide member 20.
  • the spring device 22 consists essentially of an elongated leaf spring 23 which is screwed onto the slide assembly 13 at the bottom and extends up into the backrest frame 17, and a guide pocket 24 fastened thereon, the details of which can be seen in FIGS. 4 and 4a and are described later. .
  • FIGS. 2a and 2b show the slide assembly 13 on a larger scale and in two cuts at 90 ° to each other.
  • a perpendicular rectangular tube 25 is welded onto the support tube 12 of the synchronous adjustment mechanism 6.
  • the slide member 20 is mounted for longitudinal movement over a distance of approximately 1.5 ⁇ 2 cm. The path of movement is given by elongated holes 27 which are penetrated by tubular bolts 28 mounted in the rectangular tube 25.
  • the slide member 20 is under pressure from strong coil springs 29, the zwi see its underside provided with spring guides 31 and the support tube 12 are inserted with bias.
  • the upper end 32 of the slide member 20 is in pressure contact with the lower end of the component 17 ′ from the backrest frame 17.
  • FIG. 3 The position of the slide unit 13 within the support arrangement 16 can be seen in FIG. 3.
  • 12 denotes the support tube which is mounted in fork brackets 33 of the synchronous adjustment mechanism 6 mentioned.
  • 9 ' correspond to the lever arm 9 of Fig. La tabs, and with 34 a pair of brackets parallel to the tabs 9' of the synchronous adjustment mechanism 6 according to CH Patent No. 636 252.
  • the support arrangement 16, which is welded sideways to the rectangular tube 25, contains a frame construction 35, not shown in detail, of individual supports, each of which is connected to a vertical frame member 36 at its outer ends.
  • FIG. 3 further shows the fastening of the elongated leaf spring 23 to the rectangular tube 25 of the slide unit 13.
  • the backrest frame 17 is shown in section along the line IV-IV in Fig. La.
  • the component 17 ' which is shaped, for example, as a plywood shell, is, as mentioned, at the bottom / outside each in a dashed line and is detailed in FIG described pivot bearing 37/38/39 held.
  • the guide pocket, generally designated 24, for the leaf spring 23 is attached essentially centrally to the backrest component 17 '. According to FIG. 4a, it consists of a stop housing 42 with an elongated cavity 43, in which a cam 44 placed or formed on the leaf spring 23 can move longitudinally between two end stops 45.1, 45.2.
  • the cam position at the lower end stop 45.1 fixes the backrest position in approximately axial alignment with the slide unit 13, while the cam position at the upper end stop 45.2 coincides with an approximately clockwise deflection of 15t20 0 of the upper backrest part 14 'into the position shown in broken lines.
  • the slide member 20 is pushed downward against the progressively increasing preload of the springs 29 into an equilibrium position corresponding to the size of the pressure force Q, ie the additional inclination of the backrest is dependent on the pressure force Q and disappears again when the latter becomes zero.
  • the movement path of the Schieberglie- is limited I of 20 by the length of the oblong holes 27.
  • the utilization of the possible slide path would mean that the backrest upper part 14 would be hit hard with full deflection.
  • This is avoided by the actuating spring device 22 as follows:
  • the leaf spring 23 has two kink points 46.1 and 46.2 above the slide unit 13, by means of which the leaf spring 23 is given longitudinal elasticity in addition to a clockwise bias. The latter has the result that a soft braking effect results when the cam 44 hits the upper end stop 45.2 (FIG. 4a).
  • Said pivoting bias causes the leaf spring 23 not to bend outwards but rather inwards against the component 17 'when the longitudinal pressure increases.
  • the size of the longitudinal elasticity of the leaf spring 23 and its pivoting bias by means of the kinks 46.1 and 46.2, and the free movement of the cam 44 in the guide pocket 24 can achieve a value for the deflection pressure force Q and a largely impact-free braking of the deflection movement of the upper backrest part 14 in its position 14 '.
  • the seating furniture parts are designed from the bottom up to the height of the lines KK as described above.
  • a headrest frame 53 which carries the headrest padding 53 ", is built up via a hinge joint 52 provided on both sides.
  • the headrest frame 53 can in principle contain a plywood shell part 53 'bent according to the component 17' La, lb with 23 designated leaf spring is extended beyond the guide pocket 24 to about 1/3 the height of the headrest frame 53 and hereinafter referred to as 54.
  • Up to the height of the line KK it also corresponds in shape to the leaf spring 23.
  • the hinge joints 52 At the height of the hinge joints 52, it is provided with a pre-curvature 55 which is stiff enough on the one hand to support the basic position of the leaf spring, which is still only supported by the hinge joints 52 Headrest scaffolding. Furthermore, the leaf spring 54 is fixedly connected to the headrest frame 53 at its upper end.
  • the leaf spring 54 When the backrest frame 17 is pivoted back into the position shown with broken lines, the leaf spring 54 also moves upward analogously to the displacement of the cam 44 in the guide pocket 24. Since the hinge joints 52 only allow the distance to be increased in the middle of the backrest of the curved shell parts 17 'and 53', the leaf spring 54 must be aligned precisely with this zone. When the leaf spring 54, which is firmly connected to the headrest frame 53, is pushed upward, the headrest frame 53 pivots into a pivoting position, narrowing the pre-curvature 55, in which it is approximately parallel to the basic position at a distance.
  • the counterclockwise inclination of the headrest 51 in its position shown with a broken line depends - apart from the movement path of the leaf spring 54 - essentially on the horizontal distance of the connecting line between the hinge joints 52 and the leaf spring 54.
  • the headrest tilt adjustment can be done by moving the pivot point forwards or backwards on the hinge joints 52 can be selected.
  • Both the seating furniture according to FIGS. La, 1b and according to FIGS. 5a, 5b can be provided with armrests 61 on both sides. These armrests are articulated on the one hand at the front end of the seat frame 4 on the synchronizing mechanism 6 at 62, and on the other hand on the bearing point 18 of the backrest frame 17. In accordance with the mutual adjustability of the two bearing points 18 and 62, which results from the description of FIGS. La, lb, the armrests 61 are also articulated in order to be able to follow the adjustment movement mentioned. Since these armrests, which emerge from FIG. 6 in a schematic longitudinal sectional illustration, are designed in the same way for the left and for the right side of the furniture, only one armrest should preferably be referred to below.
  • FIG. 6 41 denotes the upper joint bushing at the “rear” end of the armrest, which was already mentioned in connection with the description of FIG. 3. It is mounted on the journal 38 shown there.
  • An articulated bushing 63 which is of basically the same design, fixes the front end of the armrest 61.
  • the articulated sleeve 63 is mounted in the bearing 62 (FIGS. 1 a, 5 a) on a further axle journal, not designated, which is connected to the seat frame 4 and is similar to the axle journal 38.
  • Both joint bushes 41, 63 each carry a leg core 64, 65, for example in the form of a flat iron band, at the distal end of which a leg bend 66, 67 is provided.
  • the leg bends 66, 67 each of 1 to 2 cm in length are practically the same and at an angle of 35 to 60 ° from the straight line steered, and placed at the armrest bending point 68 one above the other so that the underside of the bend 66 of the upper leg core 64 is opposite the upper side of the bend 67 of the lower leg core 65.
  • Both thigh cores are on the one hand held in exact alignment with one another by the joint bushes 41, 63 and on the other hand are held in their mutual relationship in a pocket 69 made of a flexible covering material, for example a plastic-coated textile.
  • FIG. 6a shows the section along the lines a 1 -a 1 and a 2 -a 2 in FIG. 6
  • FIG. 6b shows the pocket in the stretched-out position when empty
  • FIG. 6c shows the pocket profile at the bending point 68 in on a larger scale.
  • the leg cores 64, 65 are surrounded by the relevant pocket sections 69.1 and 69.2 (FIG. 6b) and embedded in a foam casing 70.
  • the latter is surrounded by a cushion cover 71, which extends over the entire armrest and expediently leaves the two joint bushes 41, 63 free.
  • 6b and 6c show the design of the pocket 69.
  • Longitudinal seams 72 define the width
  • transverse seams 74.1, 74.2 define the longitudinally overlapping lengths for the receiving openings 73.1, 73.2 (see also FIG. 6c) for the leg cores 64, 65 .
  • the upper leg core 64 and the lower leg core 65 or their end bends 66, 67 are separated from one another at the armrest bending point 68 by a pocket double 75 located between the transverse seams 74.1 and 74.2.
  • the pocket double 75 avoids direct contact of the leg end bends 66, 67 (FIG. 6) and is expediently appropriately reinforced.
