Definitions

P Di invention relates to a chair, in particular the seats of public transport, comprising a seat frame and a seat disposed on the frame suspension, which serve as a carrier for a padding.
the known seating furniture for the specified purpose in relation to the suspension, which in a known embodiment is formed by an upper suspension made of FORM-WIRE spring strands stretched over a fixed frame or a steel strip frame and a spring base constructed from coil springs , wherein the front seat edge is formed by means of a cushioning built on the suspension, ie in particular the hard seat edges formed by the frame elements of the upper and lower springs are cushioned.
the disadvantage of the known suspensions is on the one hand in their great height of the seat, which requires very strong upholstery, particularly in the front seat area, and on the other hand in that the seats have only unsatisfactory lateral stability due to the spring suspension by means of spiral suspension in spring cores.
the known suspensions therefore require a considerable amount of production without, in terms of seating comfort, in particular a uniformly pressure-free seat support to ensure the tongue both in the seating area and in particular in the thigh area.
the present invention is therefore based on the object of creating a piece of seating furniture which has a simple structure without loss of spring properties and accordingly requires only a small amount of production and assembly work and, if necessary, repair work.
the invention is that the P-Isterauflage attached to a separate cushion frame and the cushion frame is held as a whole on the seat frame.
a structurally simple upholstery is created, which is easy to maintain and allows a simple replacement of a defective part without the aid of tools or possibly simple hand tools, with the replacement of only the defective part element and not the replacement of the entire seat being necessary .
the upholstery is formed by an upholstery plate which is shaped in accordance with the upholstery frame and is held against the frame by means of the cover covering the upholstery, the upholstery frame advantageously having blunted hooks resting on the frame of the seat frame after it has been fastened Hooking the upholstery cover and provided with elements for clipping onto the seat frame.
the upholstery frame is advantageously provided on its upper spar with one or more brackets engaging behind the frame of the seat frame or a catch arranged on the seat frame and on its lower spar with one or more bracket pegs which interact with a bolt arranged on the seat frame , which enables a simple but nevertheless secure mounting of the upholstery frame, ensuring that the upholstery frame is clipped onto the seat frame.
a latch bolt loaded in the closing direction by means of a spring is advantageously used as the latch, which - in relation to the movement of the upholstery frame when it is attached - has a position oriented radially to the swiveling circle of the retaining bracket and the latching lug of which has a curved outer surface which serves as a sliding surface for the latching catch owns.
the latch nose is advantageous here stepped on its inner locking surface, whereby any manufacturing tolerances are compensated for. regardless of existing manufacturing tolerances, the pad frame is firmly held on the seat frame.
the belt is expediently provided at its free end with a slot having a curvature of more than 90 ° for hanging a pull rope.
the suspension consists of an upper suspension and a lower suspension, both of which are formed by form-wire spring strands, the FORM-WIRE spring strands of the upper suspension to form the front seat edge in a direction running transversely to the crank deflections are bent back and the spring base also consists of FORM-WIRE spring strands, each of which is individually clipped to one of the FORM-WIRE spring strands of the upper suspension and the ends of which are attached to the seat frame regardless of the strands of the upper suspension.
Such suspension satisfies all requirements in terms of seating comfort and manufacturing costs.
the suspension which is already inherently low due to its construction, therefore also requires a lower upholstery structure in relation to the known suspensions and thus has such a low overall height that it can be laid the spring level in the frame level is possible.
the suspension allows the setting of the spring properties within wide limits by choosing the FORM-WIRE spring elements according to material, thickness and in particular dimensioning of the crank deflections in the longitudinal and transverse directions of both the spring and the spring.
the spring strands of the upper suspension can be clipped together in the manner known and customary in the case of FORM-WIRE suspensions and tensioned transversely against the frame. However, due to their training, they are also free, i.e. be guided together without clipping and / or other supporting connection. Here, for further stabilization. Regulation of the spring properties an elongated or kinked guide of the free ends of the strands of the spring base can be provided, advantageously in such a way that the free ends of the FORM-WIRE spring strands of the spring base directed against the rear seat edge are stretched and the ends of the FORM wire directed against the front seat edge WIRE spring strands of the spring base run in a zigzag shape up to their fastening point.
the FORM-WIPE spring strands of the spring base are expediently clipped to the associated FORM-WIRE spring strands of the upper suspension, the FORM-WIRE spring strands having differently dimensioned crank deflections in the longitudinal and transverse directions and the crank deflections of the FORM-WIRE spring strands Under the spring suspension, grip under the FORM-WIRE spring strands of the upper suspension.
the strands of the lower spring tion with the strands of the upper suspension on the longitudinal branches of the crank deflections clipped and the dimensioning is such that the free longitudinal branches of the FORM-WIRE spring strings of the spring suspension engage under the crank deflections of the FORM-WIRE spring strands of the upper suspension on one transverse branch each.
Fig. 1 of the drawing shows the perspective view of a seat frame 1 with suspension 2, which serve as a support for a cushion cover.
the Polsterholzl A ge attached to a separate cushion frame 4 and the cushion frame 4 is held as a whole on the seat frame 1.
the - not shown in the drawing upholstery is formed by a corresponding to the upholstery frame 4, the spars 5, 8 of the pole sterframes partially encompassing pad, which is held by means of the covering covering the padding against the frame.
the upholstery frame 4 is provided with blunted hooks 17, after it has been fastened to the seat frame 1 on its frame, for hooking in the upholstery cover and with elements for clipping onto the seat frame.
fastening by clipping or fastening by means of Velcro can also be provided.
the elements used to clip the upholstery frame onto the seat frame consist of one or more brackets 7 and one or more brackets 7 arranged on the upper spar 5 of the upholstery frame, behind the frame of the seat frame 1, or a catch 6 arranged on the seat frame - see FIG. 1 on the lower spar 8 of the upholstery frame are arranged latching catches 9 which cooperate with a bolt 10 arranged on the seat frame 1.
a latch or jaw bolt loaded in the closing direction by means of a spring 11 is provided as a latch, which - in relation to the movement of the cushion frame when it is attached - has a position oriented radially to the swiveling circle of the retaining bracket and the latch nose 17 of which is curved , As the sliding surface for the bracket catch 9 serving outer surface 13.
the locking lug 12 is stepped on its inner locking surface.
the bolt 10 is further provided at its free end 14 with a slot 15 having a curvature of more than 90 ° for hanging a pull cable 16.
the suspension shown in FIG. 6 of the drawing consists of an upper suspension and a lower suspension, the upper suspension being formed by form-wire spring strands 18.
FOPM-WIRE spring strands made of spring steel wire are understood to mean curved elements in one plane, in which the deflections have an essentially crank-like rectangular deflection. In recent times, they have been increasingly used as spring elements instead of the elements that were more widespread in the past, with bends in regular waves. As spring elements tensioned in one plane, they are ideally suited for the construction of large-area suspensions, e.g.
the form-wire spring strands 18 are bent back in a small bending radius in a direction transverse to the crank deflections in order to form the front seat edge, while the spring base also consists of FORM-WIRE spring strands 19, each individually are clipped with one of the FORM-WIRE spring strands 18 of the upper suspension and the ends of which are fastened to the seat frame 1 independently of the strands of the upper suspension.
the FORM-WIRE spring strands of the upper suspension can be cross-connected to one another in the usual and known manner in the case of suspensions, as in the case of the embodiment shown in FIG. 1, but they are - as in the case of 1e of the embodiment of FIG.
FIG. 2 connected to an assembly unit expediently guided freely for the purpose of improving the adaptation options with regard to the spring properties, ie not clipped together or otherwise connected laterally against the seat frame 1.
the illustration of Fig. 2 also clearly shows that the upper suspension is bent back under permanent deformation, so that the suspension is mounted essentially stress-free, which basically the size of the Rieger radius can be chosen freely according to the conditions required, a back bend with the smallest possible Bending radius, however, is possible and is generally appropriate.
the free ends 20 of the FORM-WIRE spring strands 19 of the spring base directed against the rear seat edge extend in a stretched manner and the ends 21 of the FORM-WIRE spring strands 19 of the spring base directed against the front seat edge extend in a zigzag shape up to their fastening point, thereby creating a Correct support and suspension in both the buttocks and thighs and, in addition, good transverse stabilization of the suspension, which prevents the suspension from swimming, which eliminates the need for cross-locking of the spring strands and bracing against the seat frame. In this way - apart from the simplification of production - the possibilities of adapting the spring properties according to the individual needs are significantly improved compared to known suspensions.
the FORM-WIRE spring strands 19 of the spring suspension are clipped to the associated FORM-WIRE spring strands of the upper suspension 18 on the one-sided longitudinal branches of the crank deflections, the FORM-WIRE spring strands 18, 19 in the longitudinal and transverse directions in this way differently dimensioned crank deflections have that the free longitudinal branches 22 of the FORM-WIRE spring strands of the spring suspension engage under (only) one transverse branch 23 at each of the crank deflections of the FORMWIRE spring strands of the upper spring suspension.
other dimensions are possible.
the ends of the FORM-WIRE spring strings of the lower suspension and the upper suspension are each jointly fastened in rows in a mounting rail 25.
the upholstery pad which is shaped in accordance with the contours of the upholstery frame and is provided with a circumferential groove for gripping the spars, is first placed on the upholstery frame 4 and the reference sheet is stretched over the padding pad by hooking into the blunted hooks 17, which is therefore due to the elasticity of the Upholstery fabric is held against the upholstery frame. Then the upholstery frame is placed on the seat frame in such a way that the bracket 7 arranged on the upper spar 5 of the upholstery frame engages behind the catch 6 arranged on the seat frame - see FIG. 1 - whereupon the entire upholstery frame is pivoted downwards.
bracket catches 9 arranged on the lower spar 8 of the cushion frame come to rest on the outer curved outer surfaces 13 of the bolt 10 arranged on the seat frame 1, on which they slide while pivoting the bolt against the action of the spring 11 until they snap into the jaw opening of the bolt.
the upholstery frame is thus held firmly against the seat frame, any manufacturing tolerances being compensated for by the graduated design of the inner holding surface of the bolt in that the bolt automatically searches for the catch corresponding to the circumstances.
