Person support apparatus with exit detection system and/or scale system
First Claim
1. A person support apparatus comprising:
- a frame;
a support surface adapted to support a person thereon;
a plurality of load cells having a nose and a body, each of the load cells coupled to the frame and the support surface such that a weight applied to the support surface is detected by the plurality of load cells;
a first channel dimensioned to receive a nose of a first one of the plurality of load cells and constrain the first load cell in a first direction but not a second direction when the nose of the first load cell is inserted into the first channel, the first direction being perpendicular to the second direction; and
a second channel dimensioned to receive a nose of a second one of the plurality of load cells and constrain the second load cell in the second direction but not the first direction when the nose of the second load cell is inserted into the second channel.

Abstract
A person support apparatus, such as a bed, cot, recliner, chair, stretcher, or the like, includes a frame, a support surface, a plurality of load cells, and first and second channels dimensioned to receive noses of at least one of the load cells. The first channel constrains a first one of the load cells in a first direction but not a second direction that is perpendicular to the first direction. The second channel constrains the second load cell in the second direction but not the first direction. The person support apparatus may also include a plurality of load cell brackets that are each adapted to support an end of one of the load cells. When included, the load cell brackets are constructed such that no forces from the support surface, other than weight forces, are applied to the load cells after the support surface is coupled to the frame.
