Abstract:
A bed frame comprising:a base frame having a head end, a foot end, and opposite longitudinally extending sides, a carriage mounted on the base frame for longitudinal shifting of the carriage relative to the base frame along a longitudinal axis, an articulating upper frame mounted on the carriage for longitudinal shifting therewith and comprising at least an upper body section and a seat section, the upper body and seat sections being longitudinally spaced apart and transversely extending with the upper body section tiltable relative to the seat section, a drive pivotally connected at a first end to the upper body section and pivotally connected at a second end to the base frame for tilting the upper body section relative to the base frame, a link pivotally connected at a first end to the upper body section and pivotally connected at a second end to the base frame such that tilting of the upper body section relative to the base frame results in longitudinal shifting of the carriage with respect to the base frame, and wherein a pivot point at which the drive is pivotally connected to the upper body section and a pivot point at which the link is pivotally connected to the upper body section are substantially disposed along a common pivot axis substantially perpendicular to the longitudinal axis.
