摘要：
A deformable body, wherein the body is constructed from a multiplicity of layers of a polymer construction material and in which a construction direction is defined perpendicular to the layers. The body preferably comprises layers with a multiplicity of curve pairs (10) which are formed by the construction material and which run in the same direction as one another, the curve pairs comprise in each case two periodic curves (20, 30) running oppositely with respect to one another, and the curve pairs comprise portions of maximum spacing to one another (40, 41, 60, 61) and portions of minimum spacing to one another (50, 51, 70, 71). In one part of the layers, in adjacent curve pairs (10), at least one portion of maximum spacing (41) of one curve is connected to a portion of maximum spacing (60) of an adjacent curve, in a further part of the layers, in adjacent curve pairs (10), at least one portion of maximum spacing (41) of one curve is not connected to a portion of maximum spacing (60) of an adjacent curve, in a further part of the layers, in adjacent curve pairs (10), at least a part of the portions of minimum spacing (50, 51) are connected to one another, and in a further part of the layers, in adjacent curve pairs (10), at least a part of the portions of minimum spacing (50, 51) are not connected to one another. The invention also relates to a method for producing the body and to a device for supporting and/or bearing a person having the body according to the invention. The body may be used inter alia as a mattress or as a vehicle seat.
技术问题语段：
The present invention relates to a deformable body that can be used as a mattress or a seat, among others. The body is made up of layers of a polymeric building material with curves formed by the material that touch each other. The invention aims to provide a body that allows air to be exchanged through it, providing a higher level of comfort for the person sitting or sleeping on it. The invention also allows for the creation of different levels of flexibility in different areas of the body, similar to how a spring mattress works. The invention can be produced efficiently and individually, and it is also easy to integrate electronic elements or sensors.
技术功效语段：
The present invention is a deformable body made of layers of a polymeric building material with pairs of curves formed by the material. The body has a different compression hardness in different directions, and the compression dynamics can be adjusted by designing the curves. The body can be used as a mattress or a seat, and it allows air to be exchanged through the body. The invention also provides a method for producing the body and a device for supporting and/or deforming the body. The technical effects of the invention include improved comfort, adjustable compression hardness, and efficient and individualized production.
