PCT No. PCT/AU92/00688 Sec. 371 Date Jun. 29, 1994 Sec. 102(e) Date Jun. 29, 1994 PCT Filed Dec. 31, 1992 PCT Pub. No. WO93/12969 PCT Pub. Date Jul. 8, 1993Foot retainer (11) has a pair of flexible PVC straps (14) and (15) joined at their upper ends to form headpiece (19). Batten (21) is connected to headpiece (19) and base (26). Headpiece (19) rotates between a prone position and an upstanding position. The retention assembly is biased to its upstanding position by an elasticized tensioner (22). The base (26) is bonded to the back face of a velcro-like surface for attachment to a surfboard. In an upstanding attitude batten (21) is inclined upwardly at an acute angle to base (26) to form a jaw into which straps (14) and (15) can move under the sideways action of a rider's foot. This action against straps (14) and (15) causes headpiece (19) to pivot and move downward to partially envelop the upper area of the foot which is thus retained by the assembly. |
