PROSTHETIC FOOT WITH SPACED SPRING ELEMENTS

The invention relates to a prosthetic foot, comprising:a. a connector (16) configured to connect the prosthetic foot to a lower limb prosthesis;b. a base spring (12) having a toe end portion and a heel end portion;c. a top spring assembly (14), comprising:i. a first spring member (40) having a distal end and a proximal end;ii. a second spring member (42) positioned between the base spring (12) and the first spring member (40), the second spring member (42) having a distal end and a proximal end;iii. a first spacer (44) positioned between the distal ends of the first and second spring members (40, 42);iv. a second spacer (46) positioned between the proximal ends of the first and second spring members (40, 42), the first and second spacers (44, 46) configured to space the second spring member (42) away from the first spring member (40) when the prosthetic foot is in a rest state, wherein during use of the prosthetic foot, a portion of the first spring member (40) spaced between the distal and proximal ends of the first spring member (40) moves relative to the second spring member (42);v. a distal end portion connected to the base spring (12) and extending substantially horizontally;vi. a proximal end portion connected to the connector (16);d. a heel cushion (18) mounted to the base spring (12) at a location spaced forward of a heel end (22) of the base spring (12), the heel cushion (18) arranged to contact a bottom surface of the second spring member (42) during use of the prosthetic foot.
