1. A patient support apparatus for supporting a patient, said patient support apparatus comprising:
a support structure;
a side rail movable relative to said support structure between a raised position and a lowered position, said side rail comprising an interior;
a support arm assembly coupling said side rail to said support structure, said support arm assembly including:
a first support arm pivotally coupled to said side rail about a first side rail pivot axis and pivotally coupled to said support structure about a first frame pivot axis, and
a second support arm spaced from said first support arm, said second support arm pivotally coupled to said side rail about a second side rail pivot axis and pivotally coupled to said support structure about a second frame pivot axis;
an actuator disposed at least partially within said interior of said side rail and configured to move said side rail between said raised position and said lowered position;
an input device for generating an input signal; and
a controller in communication with said actuator and said input device and configured to receive said input signal from said input device to control said actuator based on said input signal.
