Seat with adjustable support system
First Claim
1. A device for supporting a user'"'"'s sacral anatomy in a seated position, the device comprising:
- a seat having a seat back with a front portion, a rear portion and a frame, the front portion including a support cushion therebehind;
a support member operably connected to the frame;
an adjustable sacral support member pivotally connected to the support member,an adjusting assembly, actuatable by a seated user, and connected to the sacral support member to move the sacral support member relative to the support member and thereby toward and away from a rear surface of the front portion of the seat back;
a second support member operably connected to the frame and spaced from the sacral support member;
a complementary support member operably connected to the second support member to permit the seated user to control the fit and comfort of the seat back to the spine and adjacent anatomical structures;
wherein the sacral support member is operably connected to the complementary support member to provide a proportional support there between as the sacral support member and the complementary support member are actuated;
an actuator operably connected to the adjusting assembly and sacral support member and the complementary support member, wherein the actuator is configured to control the position of the sacral support member and the complementary support member relative to the frame; and
wherein the sacral support member is configured to extend a first maximum distance relative to the frame, and the complementary support member is configured to extend a second maximum distance relative to the frame, wherein the first maximum distance is greater than the second maximum distance.

Abstract
A sacral support assembly for use with a seat is provided. The seat includes a seat frame. An adjustable sacral support assembly is connected to the seat frame. The sacral support assembly includes a sacral support member adapted to support the sacrum of a seated user even when an obstruction is located between the user and the sacral support assembly. A method is also provided for delivering primary support to a user'"'"'s sacrum and sacral-pelvic anatomy and secondary support to the remaining regions of the spine and/or adjacent anatomy to reduce fatigue, increase comfort, structural balance, stability, and posture control for a user, and a system for adjusting and controlling the load distribution from the sacral anatomy to the spine and other anatomical structures adjacent to a user'"'"'s sacrum, for example, the pelvis, lumbar, thoracic and cervical regions.
