Benefits of technology
[0013]It is an object of the present invention to overcome, or at least reduce, the problems associated with the manufacture of conventional protective material and with protective wear made therefrom.
Problems solved by technology
There are, however, a number of problems with this arrangement.
Provision of different sizes can be expensive or inconvenient.
Also, closely fitting articles can restrict movement of the wearer, especially when worn on or near joints.
However, the foram elements of the bandage touch one another at their base, which restricts the stretchability of the material as a whole and is also designed to be worn with the elements in contact with the skin, which would restrict movement.
A moulded foam article can only correctly fit a joint when in one position.
When the joint moves, the article will no longer fit correctly.
This may reduce the protection it affords.
Such materials are time consuming to produce.
Also, such materials can generally only easily be flexed in a direction perpendicular to that of the strips of foam.
Flexing the material in a direction along the length of the strips involves flexing the strips themselves which, depending on the type of foam used, can be difficult.

Embodiment Construction
[0040]Referring to FIG. 1, a flexible material comprises a plurality of cubes 1 of a resilient closed-cell polyethylene foam, of side approximately 12 mm and with corners of radius approximately 2.5 mm, joined with a hot melt adhesive to a fabric substrate 2. The cubes 1 are evenly arranged, each cube being spaced from adjacent cubes by approximately 2 mm. The fabric 2 is a resiliently stretchable knitted fabric, preferably one comprising polyester or elastane fibers.
[0041]A margin of fabric 2 is provided around the periphery of the cubes 1. Along the edges of the fabric at opposite ends respectively there are strips 3 of VELCRO(™), only one of which is shown.
[0042]Referring to FIG. 2, a protective armband 4 is shown being worn on part of an arm 5. The armband 4 is formed from a generally rectangular piece of material of the type shown in FIG. 1 but which in this case comprises a fabric substrate 6 bonded to both sides thereof with a plurality of foam cubes 7 sandwiched therebetween...

Abstract
A flexible material includes a plurality of separate resilient elements joined to a flexible, resiliently stretchable substrate. Such a material is suitable for providing protective war for human and animal bodies. Preferably, the elements includes a foam material such as a closed cell polyethylene foam and the substrate includes a knitted fabric. In an advantageous embodiment, a second flexible substrate is bonded over the elements to sandwich them between the two layers of substrate.
