Abstract: A helmet 100 includes a helmet shell 16, an outer liner layer 14 fixed inside the helmet shell 16; and an inner liner layer 12 positioned against the outer liner layer 14; the outer liner layer 14 having a dome-like concave curved internal surface; the inner liner layer 12 having a dome-like convex curved external surface; the said surfaces of the inner and outer liner layers 12, 14 being substantially spherical where they overlap for allowing rotational sliding movement of the inner liner layer against the outer liner layer; a rotation-limiting mechanism being provided for limiting rotation between the inner and outer liner layers; and at least one of the said surfaces of the inner and outer liner layers 12, 14 having recesses 18 therein for weakening the layer and for facilitating crushing of the layer when a sufficiently large radial force is applied, loosening the inner liner layer 12 within the outer liner layer 14.

Abstract: A body protector laminate 10 comprising a first laminated layer having first and second skins 12, 14 of fabric bonded to either side of a first inner foam core 13, one or more cuts 16, 18, 20 being provided through the first skin 12 and through the first inner foam core 13, and one or more further cuts 22, 24 being provided through the second skin 14 and through the first inner foam core 13, enabling compound bending of the laminate for substantially fitting to or against a body having convex and concave surfaces.

Abstract: A safety device (18, FIG. 1) for a horse 12 comprises an air bag 24 and an inflation means, the safety device (18) being adapted to be mounted to a saddle 14 or saddle pad 16. The airbag 24 is substantially horseshoe shaped and when inflated is adapted to extend around a horse's hind quarters up one flank, across the back of the horse, and down the other flank. Inflation of the airbag 24 is triggered when the safety device is moved to a substantially vertically disposed position as encountered in a rotational fall. A second embodiment of airbag 42 with a pyramidal shape is shown in FIG. 4.
