A permanent non-resorbable implant allows surgical replacement of cartilage in articulating joints, using a hydrogel material (such as a synthetic polyacrylonitrile polymer) reinforced by a flexible fibrous matrix. Articulating hydrogel surface(s) are chemically treated to provide a negative electrical charge that emulates the negative charge of natural cartilage, and also can be treated with halogenating, cross-linking, or other chemical agents for greater strength. For meniscal-type implants, the reinforcing matrix can extend out from the peripheral rim of the hydrogel, to allow secure anchoring to soft tissue such as a joint capsule. For bone-anchored implants, a porous anchoring layer enables tissue ingrowth, and a non-planer perforated layer can provide a supportive interface between the hard anchoring material and the softer hydrogel material.

A four-bar hinge linkage and fold-down support assembly, such as an armrest, seat bottom, table top and the like especially suited for marine use in watercraft applications. The support member is pivotally supported by first and second four-bar hinge linkages for articulation from a stationary upright support structure affixed to the watercraft. Each of the four-bar hinge linkages comprises a support-structure-mounting bracket, a main hinge link, a shorter control / locking link and a support-member-mounting bracket. Each of the linkages articulates the support member between an upright stored position and a folded-down in-use position wherein, the swinging end of the control / locking link swings up and beneath the hinge link so that an end edge of the control / locking link abuts in line-to-line contact at an abutment locking point along the lower edge of the hinge link, each linkage being thus locked together to form a triangular support truss. The abutment locking point placement provides a strong support structure, reduces the possibility of creating a pinch point and is oriented well forward of the linkage pivot point so that the links will not push by one another.
