摘要：
An articulating bed incorporates a support frame (10) with a head end, a foot end and having side frame members (31). A carriage (12) having a seat support (14) is carried by the frame, mounted with wheels (25) engaging the side frame members to translate from a first position through a range progressing toward the head end to a fully translated position. An upper body support (16) is rotatably connected to the carriage and carries a mattress support (15). At least one telescoping rotation strut (18) is attached at a first end and rotates through an axle pivotally attached to the side frame members. The telescoping rotation strut engages at a second end the upper body support. At least one fixed length rotation arm (20) is carried at a first end by a rotating tube (22) and pivotally attaches to the upper body support at a second end. The rotating tube is mounted on wheels (23) constrained in a track (24) and translates laterally in the track to contact a track end proximate the head end of the frame at a termination of a first range of motion. The telescoping strut approaches a vertical orientation and transfers reaction forces resulting from translation of the carriage to the fixed length rotation arm, whereupon the telescoping rotations struts extend.
