Articulating bed with lumbar and head adjustment
An articulating bed incorporates a support frame having an upper body support section. A lumbar actuation lever extends from a rotatable torque tube with angle arms extending from the torque tube to a lumbar support element. The lumbar support element is retracted against the upper body support section creating minimal deflection in a lumbar region of a mattress. The torque tube is rotated with to elevate the lumbar support element. A head support bracket is mounted to a neck angle adjustment section. The neck angle adjustment section is aligned with the upper body support section. or rotated about hinge elements to provide an angled head and neck position with respect to the upper body support section.
1. A lumbar support adjustment mechanism for an articulating bed comprising:
an actuator pivotally attached to an upper body support section with a bracket, said actuator including a ram;
a lumbar actuation lever pivotally attached to the ram and extending from a torque tube rotatable in bearing blocks mounted to the upper body support section;
angle arms extending from the torque tube and attached to a lumbar support element through apertures in the upper body support section;
said lumbar support element retracted against the upper body support section with the ram in a first position creating minimal deflection in a lumbar region of a mattress supported on the upper body support section and said torque tube rotated with the ram in a second position extending the angle arms through the apertures to elevate the lumbar support element.
2. The lumbar support adjustment mechanism as defined in claim 1 wherein the lumbar support element is substantially cylindrical for contact with a mattress resting on the upper body support section.
3. A neck angle adjustment mechanism for an articulating bed comprising:
an actuator pivotally supported by a bracket extending from a brace element of an actuation mechanism of an upper body support section, said actuator incorporating a ram;
a head support bracket pivotally attached to the ram and mounted to a neck angle adjustment section;
said neck angle adjustment section aligned with the upper body support section with the ram in a first position, said bracket urged to rotate the neck angle adjustment section about hinge elements mounted to the upper body support section to provide an angled head and neck position with respect to the upper body support section with the ram in a second position.
4. An articulating bed comprising:
a support frame;
an articulating section supported on the support frame and having a seat section and an upper body support section;
an actuator pivotally attached to the upper body support section with a bracket, said actuator including a ram;
a lumbar actuation lever pivotally attached to the ram and extending from a torque tube rotatable in bearing blocks mounted to the upper body support section;
angle arms extending from the torque tube and attached to a lumbar support element through apertures in the upper body support section;
said lumbar support element retracted against the upper body support section with the ram in a first position creating minimal deflection in a lumbar region of a mattress supported on the upper body support section and said torque tube rotated with the ram in a second position extending the angle arms through the apertures to elevate the lumbar support element.
5. An articulating bed comprising:
a support frame;
an articulating section supported on the support frame and having a seat section and an upper body support section;
an actuator pivotally supported by a bracket extending from a brace element of an actuation mechanism of the upper body support section, said actuator incorporating a ram;
a head support bracket pivotally attached to the ram and mounted to a neck angle adjustment section;
said neck angle adjustment section aligned with the upper body support section with the ram in a first position, said bracket urged to rotate the neck angle adjustment section about hinge elements mounted to the upper body support section to provide an angled head and neck position with respect to the upper body support section with the ram in a second position.
6. An articulating bed comprising:
a support frame;
an articulating section supported on the support frame and having a seat section and an upper body support section;
an actuator pivotally attached to the upper body support section with a bracket, said actuator including a ram;
a lumbar actuation lever pivotally attached to the ram and extending from a torque tube rotatable in bearing blocks mounted to the upper body support section;
angle arms extending from the torque tube and attached to a lumbar support element through apertures in the upper body support section;
said lumbar support element retracted against the upper body support section with the ram in a first position creating minimal deflection in a lumbar region of a mattress supported on the upper body support section and said torque tube rotated with the ram in a second position extending the angle arms through the apertures to elevate the lumbar support element;
a second actuator pivotally supported by a second bracket extending from a brace element of an actuation mechanism of the upper body support section, said second actuator incorporating a second ram;
a head support bracket pivotally attached to the second ram and mounted to a neck angle adjustment section;
said neck angle adjustment section aligned with the upper body support section with the second ram in a first position, said bracket urged to rotate the neck angle adjustment section about hinge elements mounted to the upper body support section to provide an angled head and neck position with respect to the upper body support section with the second ram in a second position.
