Abstract

An occupant support such as a bed 20 includes an articulable deck 34 having an upper body section 44 and a section 46 or 74 longitudinally adjacent to the upper body section. The upper body section is pivotable relative to the adjacent section about a laterally extending upper pivot axis. The upper body section may be pivoted to angular orientations between a substantially flat angular orientation and a maximum angular orientation. A siderail 86 affixed to the upper body section, includes a grip 102 having an ascending orientation relative to the upper body section. The grip is longitudinally bounded by a siderail back portion 106 located behind the grip and a siderail front portion 110 located in front of the grip. At least part of the front portion has a non-ascending orientation relative to the upper body section.

Claims

1. An occupant support comprising:

an articulable deck having an upper body section and a section longitudinally adjacent the upper body section, the upper body section being pivotable relative to the adjacent section about a laterally extending upper pivot axis between a substantially flat angular orientation and a maximum angular orientation; and

a siderail affixed to the upper body section, the siderail including a grip having an ascending orientation relative to the upper body section, the grip being longitudinally bounded by a siderail back portion located behind the grip and a siderail front portion located in front of the grip, at least part of the front portion having a non-ascending orientation relative to the upper body section.

2. The occupant support of claim 1 including:

a mattress supported on the deck, the mattress having an occupant support side spaced from the deck;

the grip being at a higher elevation than the occupant support side when the siderail is deployed.

3. The occupant support of claim 1 wherein the siderail back portion has a back transition region that blends with the grip and has a descending orientation.

4. The occupant support of claim 1 wherein the front portion comprises a front transition region and a nose.

5. The occupant support of claim 1 wherein the part of the front portion neighboring the grip has a non-ascending orientation.

6. The occupant support of claim 2 wherein the grip has an effective length and with the upper body section at an orientation of about 35 degrees, the extremity of the grip closest to the egress plane is spaced from the egress plane by a distance DE no greater than about two times the effective length L of the grip.

7. The occupant support of claim 1 wherein with the upper body section in a substantially flat orientation, the grip is at an orientation of between about 26 degrees and 45 degrees relative to a ground plane.

8. The occupant support of claim 1 wherein with the upper body section at an orientation compatible with occupant transition, the grip is at a height and at a longitudinal location that renders it accessible to and useable by an occupant transitioning into or out of the bed

9. The occupant support of claim 8 wherein the compatible orientation is about 35 degrees.

10. The occupant support of claim 8 wherein the height and longitudinal location of the grip are a function of anthropometric data.

11. The occupant support of claim 1 wherein with the upper body section at an orientation of about 35 degrees the grip orientation is approximately parallel to a ground plane.

12. The occupant support of claim 1 wherein with the upper body section at an orientation of about 65 degrees the grip is at a descending angle relative to a ground plane, the descending angle being no greater than about 45 degrees.

13. The occupant support of claim 1 wherein the grip has an approximately circular cross section having a diameter in the range of about 1.9 to about 4.1 centimeters.

14. The occupant support of claim 1 wherein the grip is at an uppermost border of the siderail.

15. The occupant support of claim 1 wherein the siderail includes a boost surface having an ascending orientation steeper than the orientation of the grip.

16. The occupant support of claim 15 wherein the boost surface faces toward the grip and is located in front of the grip.

17. The occupant support of claim 16 wherein the grip, the front portion, the boost surface and a main body of the siderail define an approximately quadrilateral opening.

18. The occupant support of claim 16 wherein the grip, the front portion, the boost surface and a main body of the siderail define an opening having a smooth, non-quadrilateral shape.

19. The occupant support of claim 18 wherein the shape is approximately circular.

20. The occupant support of claim 1 including a boost surface having an ascending orientation steeper than the orientation of the grip, the boost surface facing toward the grip and located in front of the grip, the grip, the front portion and the boost surface defining an approximate circular arc.

21. The occupant support of claim 1 wherein flanks of the grip include a recess.

22. The occupant support of claim 21 wherein the recess has an elongated serpentine shape with tapered termini.

23. The occupant support of claim 1 wherein the deck has exactly three serially distributed sections, the adjacent section being a center section longitudinally between the upper body section and a calf section.

24. The occupant support of claim 1 wherein the deck has exactly four serially distributed sections, the adjacent section being a seat section, the other two sections being a thigh section and a calf section.

25. A siderail for a hospital bed having a main body and a top rail, the top rail including a back portion with a descending back transition region, an ascending grip in front of the back transition region, and a non-ascending front portion ahead of the grip.
