<p>An impact-absorbing cell (1) having a flexible housing (2) having at least one passage (9) enabling air to pass into and out of the housing (2), and beads (4, 8) within the housing (2). The beads (3) comprise a mixture of polypropylene beads (4) and beads of sponge rubber (8). When a vehicle collides with the cell (1), the housing (2) and beads (4, 8) compress and air is expelled from the housing (2), and the cell (1) may revert to the shape that it had prior to the collision occurring.</p> |
