Definitions

  • the invention relates to a support element of a seat oroutheastern familial familial aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphizada support element of a seat or Medouracil.
  • EP 1 386 564 B1 It is known a spring element for seating and reclining furniture, EP 1 386 564 B1 which has rigid support arms on a foot part and corrugated springs at their upwardly directed ends, which are fixed rigidly to the support plate. Furthermore, the known spring element has a hardness adjustment of an elastic support body which is placed on the foot part and having support arms which can be brought into alignment or gap with the support arms of the spring element.
  • This known spring element is very expensive to assemble and therefore less economical, as well as it consists of the hardness adjustment of up to six components, which also make expensive injection molds required for their production.
  • a support element produced as a single injection molded part for upholstery pads of sitting or lying surfaces EP 0 996 349 B1 , which has leaf spring-like spring arms with end corrugated springs whose spring arms deform in the direction of an acting bearing force outermost downwards, wherein the corrugated springs are compressed.
  • This one-piece injection-molded part requires complicated injection molds and can be production technology not closed support plate, as well as desired changes in the spring properties lead to costly re-constructions of the tools.
  • the object of the invention is to provide a support element of a seat oroutheastern familial familial familial aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aphiza aporous a suspension available.
  • the spring arms are formed as quasi-rigid support arms having at their upper outer ends in each case a downwardly bent short lever arm, the conclusion forms a first bearing element and the support plate has a respective first bearing elements of the lever arms corresponding second bearing elements, the are connected to a common camp, can create a variety of possible embodiments.
  • the second bearing element may be formed on the support plate as a torsion bar spring and the first as the torsion bar embracing claw, so that the vertical forces could be absorbed by a resilient torsion.
  • the bearing element can also be designed as a cylindrical bearing pin, so that no bending moments or torsional forces are introduced into the bearing plate.
  • the separation of the components allows a specific choice of material of the respective most economical and mechanical properties, as well as the assembly of the support element and its assembly can be done in a piece of furniture by hand, without the aid of tools or additional fasteners.
  • the relatively stiff support arms deform from a vertical load on the support plate from above not in the form of a leaf spring, as their ends can not move freely downwards and outwards, but by the lever arm at the end of the support arms approximately bulbous in the direction obliquely upwards in the direction of Perpendicular through the component, the material used is applied evenly and without voltage spikes, resulting in also the durability of the inventive support element significantly increased.
  • a hardness adjuster is rotatably mounted on or under the support plate, which has at least one blocking piece for each support arm, which is in a locked position in a blocking position between the bottom of the support plate and the top of a support arm supports, which is preferably still provided with a separate casserole, which, depending on how Length of the blocking piece the first type of operation of the described suspension can be blocked immediately or later.
  • predetermined bending points are formed in the lower region of the support arms between the casserole and the foot, which are elastically deformed under heavy load so that an obliquely outward and downward fold in Support arm is generated, which elastically regresses after a relief of the support element.
  • the hardness adjuster itself has part-circular slot recesses as detent recesses into which engage from the underside of the support plate downwardly directed locking lugs, which hold the one used from below hardness adjuster and make it rotatable for another by an angular amount in the slot recesses.
  • the foot part is equipped with a reverse T-shaped downwardly extending latching bone having frontal Verrastungskerben with which the support element can be inserted directly into a plastic crossbar with corresponding receptacles for the latching bones and locked , wherein in the latching device lateral abutment surfaces for the latching bone and frontal locking lugs are provided for its rotation locking and thus a support element.
  • the support element of a seat oroutheastern familial familial consists of a rigid support plate 1 and a support member with a foot part 11 and thereof radially and obliquely upward in the direction of the support plate 1 extending support arms 3, at the upper ends of each short lifting arms 10 angled obliquely outwards below are formed, whose terminations form upwardly open bearing shells 9 as the first bearing elements, wherein the bearing plate 1 has formed as axes 5 second bearing elements, which are clipped into the bearing shells 9.
  • the axles 5 and the bearing shells 9 have circular-cylindrical or partially circular-cylindrical cross-sections, so that the bearing shell 9 can be rotated upwards and outwards by a small angular amount when loading a support element, for example by a vertical force from above, whereby a bending moment is generated which is transmitted to the support arms 3, so that they are bent upwards obliquely upward and to an imaginary vertical center axis of thennenlagerimplantations.
  • the axles 5 are slightly offset parallel to the support plate 1 integrally formed bearing blocks 6 below arranged below the support plate 1 to provide sufficient clearance for the upwardly urgent at a vertical load ends of the support arms 3.
  • Fig. 6 shows a simplest conceivable embodiment of the support element with a support element with only two support arms 3 and a simple support plate 1 without hardness adjuster 4, whereby embodiments with 3 to 8 or more support arms 3 and blocking pieces 14 are conceivable, as well as the shape of the support plate 1 freely selectable is.
  • the support member is additionally equipped with a hardness adjuster 4, which is formed substantially disc-shaped and part-circular slot recesses 8 has as a detent recesses, engage in the bottom of the support plate 1 downwardly extending notches 7, so that the hardness adjuster 4 in the slot recesses 8 is rotatably supported by an angular amount of about 45 °.
  • He has one of the number of support arms 3 corresponding number of blocking pieces 14 which extend vertically downward in the peripheral region and rest in a twisted in a blocking position position on casserole 15 on the support arms 3, whereby the described reaction of the support element is released upon application of force and so an extreme stiffening is generated.
  • the support arms 3 are equipped with elastic predetermined bending points 12, which produce a biased outwardly and downwardly fold at a very strong force.
  • the foot part 11 of the support element is provided with an inverted T-shaped latching bone 13 which extends downwardly therefrom and has the end-side latching notches 16 which with notches 22 in a latching device 19 a Cross bar 17 act together and after insertion of the latching bone 13 in the latching device 19 and a twisting abut against stop surfaces 20, which prevent further rotation, the latches 22 lock the support member against accidental loosening and turning back.
  • the hardness adjuster 4 which is latched from below under the support plate 1, has in the middle an upwardly directed, manually operated rotary knob 21, via which the hardness adjustment can be turned on or off, wherein the blocking pieces 14 may also have heels, so that still different large pivot angle of the bearing shells 9 remain possible about the bearing pin 5, and thus different levels of hardness adjustment can be realized.
  • the crossbar 17 is made of fiber-reinforced plastic and has a wave-shaped cross-section, wherein a central wave crest is extended in width in order to produce a sufficiently large locking device 19 therein and order support elements without further additional fasteners can order.
  • the rounded shapes of the undulating cross section of the crossbar 17 serve essentially to reduce stress peaks in the material in order to further increase the life of the crossbar 17 and thus the entire spring base.
