Abstract

A system for changing the width of a person support apparatus includes a bed controller for receiving a command signal indicating a command for width alteration, a first motor controlled by the bed controller for driving an extension of a first deck section of the support apparatus thereby altering the width of the first deck section, and a second motor controlled by the bed controller for driving an extension of a second deck section of the support apparatus thereby altering the width of the second deck section. The bed controller controls the first motor and the second motor in a manner that causes the first deck section to reach a first deck section width alteration limit at a first time and the second deck section to reach a second deck section width alteration limit at a second time, wherein the first time and the second time are not equal.
