AI Technical Summary
Technical Problem
Lattice-structured padding elements experience uneven pressure distribution leading to discomfort and lack of support due to varying stress points, which is challenging to address without affecting structural integrity, manufacturability, or aesthetic appearance.
Method used
A monolithic lattice-structured padding element with a body lattice and surface lattice featuring continuously variable strand cross-sections along their axes, allowing for a gradient of mechanical behavior to evenly distribute pressure and improve comfort.
Benefits of technology
The continuous variation in strand cross-sections ensures uniform stress distribution, enhancing user comfort and support while maintaining structural integrity and manufacturability.

Abstract
The invention relates to a monolithic, lattice-structured padding element (10) comprising: - a body lattice (1), - a surface lattice (11), wherein the body lattice (1) comprises at least two strands (36) connected to each other, each by a proximal strand end, characterized in that the strand cross-section of said at least two strands varies continuously along their respective strand axes from a distal end of a first strand among said at least two strands to a distal end of a second strand among said at least two strands, such that the mechanical behavior of the first strand differs from that of the second strand when the body lattice is subjected to external stress, in particular a force applied to the surface lattice.
