摘要：
An actuating mechanism for lumbar support in an articulating bed incorporates a support frame (10) for an articulating section having a seat section (14) and an upper body support section (18). An actuator (52) with a ram (54) is pivotally attached to the upper body support section with a bracket (53). A lumbar actuation Iever (56) is pivotally attached to the ram and extends from a torque tube (58) rotatable in bearing blocks (62) mounted to the upper body support section. A second actuator (70) is pivotally attached to the upper body support section with a second bracket (73) and includes a second ram (72). At least one angled lifter arm (64) extends from the torque tube and pivotally attaches to at least one Iever (65a, 65b, 65c) engaging a lumbar support element (30) through at least one aperture in the upper body support section.
