Definitions

• the invention relates to a suspension mat, in particular for the suspension of seats and the like according to the preamble of claim 1.
• Such suspension elements have so far mostly been formed by the upholstery of seats, beds or the like, which in this respect have the task of giving the user the impression of a soft seat.
• the present invention is based on the object of producing the desired impression of a soft sitting in an alternative manner.
• the suspension mat consists of elastic spring elements, which are arranged next to each other in one direction in any direction and transverse to this Direction. This creates the impression of soft sitting without any additional aids. This is because, like an upholstery, an element with an elastic surface and suitable spring comfort is achieved. However, if a three-dimensional spring-elastic element is desired, the mat can also extend in the third dimension. Nevertheless, the elements can be used independently of other parts of the seat, which is particularly advantageous when recycling the vehicle after its useful life has ended.
• the spring element consists of metallic helical springs which are turned into one another with their spirals or helices, so that in addition to the suspension in the longitudinal direction there is an operative connection transverse to the longitudinal extension of the springs.
• metallic spring band steels can also be used, which are arranged next to one another and are connected to one another transversely thereto by cross struts or flat connecting means. A flat power transmission is guaranteed in both cases.
• FIG. 2 is a side view of the suspension mat of FIG. 1,
• FIG. 3 shows a representation according to FIG. 2 in a plastically deformed position
• FIG. 4 a suspension mat in a further embodiment in section and in plan view
• FIG. 6 a suspension mat in section as a composite material
• FIG. 7 shows a section through a spring element, Fig. 8-10 a preferably metallic suspension mat in another
• suspension mat preferably made of plastic, in a further embodiment in section, in plan view and in a three-dimensional view.
• FIG. 1 shows a top view of a suspension mat 10, as is used in particular for the suspension of seats, preferably vehicle seats.
• the use of the suspension mat is not limited to the seat and backrests of all types of seating such as office chairs, seating elements, sofas or vehicle and airplane seats, but can e.g. can also be used for beds or bicycle saddles.
• the mesh base is suitable for all types of use where elastic, pressure point-free mesh base is required.
• spring elements 11 are arranged next to one another, which are connected to one another transversely to their longitudinal extension, that is to say to the first direction, for operative connection to one another.
• the first direction runs parallel to a surface of the seating, the bed or the like which can be used by a user.
• the spring elements 11, 11 ', 12, 15 are preferably metallic and can therefore be easily reused later.
• the mat is at best flame-retardant and non-flammable due to the upper material, which is particularly important in vehicle and aircraft construction.
• other materials can also be used, provided the desired elastic properties are achieved the desired elastic properties can be achieved.
• the spring elements can be arranged next to one another in any desired manner, provided that it is only ensured that a suitable force transmission is achieved to achieve the desired spring comfort, namely the impression of a soft sitting in the seat.
• the spring elements 11, 11 ', 12, 15 are preferably arranged essentially parallel to one another, as is also illustrated in FIG. 1.
• Such a suspension mat will usually be a flat structure. However, if a three-dimensional spring-elastic element is desired, the mat can also extend in the third dimension. In this case, a connection between different spring elements can also take place in the third dimension.
• the spring elements 11 according to FIG. 1 are coil springs, the spirals of which are rotated into one another in order to achieve the operative connection.
• the coil springs are parallel to each other.
• the spirals of the coil springs collide as shown in FIGS. 2 and 3 and produce the desired flat or, if necessary, three-dimensional effect by transmitting the forces to one another transversely to the longitudinal extension of the coil springs.
• FIG. 2 there is a relatively soft support with four support points in the illustration.
• the width of the coil springs is the width x, while they have a height y.
• the mat or also the coil springs can be plastically deformed as spring elements 11 'transversely to the surface in which the suspension mat 10 comes to lie.
• FIG. 3 On the one hand, the number of support points has increased from four to eight, at the same time the mat has become 25% wider, while the overall height has been reduced to y '.
• Such a mat is fundamentally harder than the suspension mat according to FIG. 2.
• Figures 4 to 13 show spring elements that can be used either in connection with the coil springs 10 or by themselves.
• These spring elements 12 consist in the exemplary embodiments of FIGS. 4 to 10 of spring steel with a width u.
• the spring band steel is bent up to a height v in a loop.
• the height v or y 'of the spring mat can be reduced to less than 10 mm in height without losing the desired sitting or lying feeling. Any construction heights are possible, but construction heights of 8 to 20 mm, preferably 10 mm, are preferred.
• these spring elements 12, like the spring elements of the first exemplary embodiment 11, 11 ′ can be connected to one another by a flat connecting means 13 (FIG. 6).
• the connecting means can be glued to the spring elements. It can be arranged on one side or on both sides of the suspension mat 10 with the spring elements 11, 11 ', 12. In principle, e.g. the central lanyard is in operative connection on both sides with spring elements.
• the connecting means 13 can e.g. in the form of a mesh, a layer, a mat or a film. However, a three-dimensional structure can also be achieved here by corresponding arrangement of spring elements and connecting means.
• the spring elements can also be connected to one another by preferably elastic cross struts 14.
• This connection by cross struts 14 is particularly suitable when spring band steel is used as spring element 12.
• spring band steel is used as spring element 12.
• the spring steel according to FIG. 4 has a different bending radius than the spring band steel in FIG. 7. This can also be used to influence the elasticity of the suspension mat.
• the spring mat as spring elements 12 has a plurality of strips of any width and length.
• plastics or other elastic materials can also be used, although preference is given to the metallic spring element.
• the individual strips can be connected to the connecting means 13, 14 in a wide variety of ways.
• the spring elements 10, 11 ', 12 can also e.g. be assembled as a plastic injection molded part.
• a corresponding embodiment is shown in FIGS. 11 to 13.
• the spring elements 15 rise from a base area 16.
• a corresponding part can be injection molded or also deep-drawn from a plastic part - or also a metallic part - with plastic deformation of the plastic.
• the mat In both cases, due to the close and high number of support points in the direction of the "to be owned” area, a full-surface seating feeling without noticeable pressure points can be achieved in contrast to previously known spring mattresses.
• the mat nevertheless adapts to the load due to the composition of individual elements every body shape on a comparable water bed, but unlike a water bed, the mat is breathable and heatable.
• the suspension mat 10 consisting of the spring elements 11, 11 ', 12 and possibly the connecting means 13, 14 can be constructed as a composite material which is used for use in seats, in particular in vehicle seats.
• This composite material can in turn comprise parts of the vehicle seat, such as the upholstery.
• the composite material can be an integral part of the vehicle seat or of parts of the vehicle seat.
• the spring mat can be made in all sizes and shapes such as rectangular, square, oval, round, triangular, etc.
• the mat can be produced with defined sink depths and hardnesses at any point, since only a corresponding selection of the spring elements or their shape is required for these points or at these points.
• the mat is very flexible and adapts to all possible basic shapes depending on the application.
• the mat does not have to be plastically deformed, for example by folding, bending or the like.
• the mat follows any basic contour. Additional brackets and / or shaped frames can be used, but are not absolutely necessary. Coiled springs lying together as in the first embodiment of FIGS. 1 to 3 cannot be used as flexibly. In particular, the mat according to FIGS. 4 to 13 does not lose its outer contour when subjected to pressure, since the pressure is absorbed by the shape of the individual spring elements.
