Abstract: A seat structure with latching-unlatching mechanism for enabling smoothly operating releaseable locking and unlocking actions between a seat-base and an inclinable seat-back hinged to the seat-base in the seat structure. Two interengageable arcs of gear teeth forming part of the mechanism engage and release selectively under rocker-lever seat-occupant control to lock and unlock the seat-back for inclinational fixation and adjustment, and, as determined by tooth-pitch in the arcs, enable positive locking to take place in a large number of specific, small-angular-difference, seat-back inclinations.

Abstract: A topographically self-stabilizing, dynamic pressure-evenizing, pressure-applying, anatomical dressing which includes a pressure-applying, acceleration-rate-sensitive, temperature and pressure responsive, cushioning layer which responds during a bandaging situation, both statically and dynamically, to maintain relatively uniform all-over pressure beneath it, and against the surface of a site, such as a surgical wound site.

Abstract: A plural-layer body-contacting protective and cushioning interface structure. This structure has a body-facing side which contacts the body, and an opposite side, and intermediate these sides, in one form of the structure, is a moisture-wicking layer, next a moisture-blocking, gas-permeable barrier layer adjacent the moisture-wicking layer, and next, an acceleration-rate-sensitive cushioning layer. In some applications, the moisture-wicking layer is omitted.
