Abstract
A padding material for protective equipment is provided. The padding material is formed from a single, integral piece of material with a cellular structure. The size and/or shape of the cellular structure is non-uniform to provide support and reduce pressure in chosen areas. One embodiment of the protective equipment includes knee pad with a shell, padding disposed in front of the knee of the wearer, the padding including a non-uniform stiffness.
Claims21
A knee pad comprising:
- an upper support configured to couple to a leg of a user above a knee;
- a lower support configured to couple to the leg of the user below the knee;
- a shell coupled to the upper support and the lower support and positioned between the upper support and the lower support;
- and
- a single, integral padding layer comprising:
- an outer surface interfacing against the shell;
- an inner surface;
- and
- a plurality of cells, each of the plurality of cells extending between the outer surface and the inner surface, each of the plurality of cells comprising:
- a channel connecting the outer surface and the inner surface;
- a longitudinal axis extending along the channel between the outer surface and the inner surface;
- and
- a cell wall enclosing the channel, the cell wall comprising a plurality of segments angled relative to the longitudinal axis and positioned along a height of the cell wall.
