Siderail assemblies and person-support apparatuses for adjustable width surface

A person-support apparatus, comprising:

• a mattress defining a notch along a length of the mattress, wherein the notch comprises a bottom and a width, the bottom is narrower than the width;
• a person-support apparatus frame supporting the mattress thereon;
• and
• a siderail assembly pivotally coupled to the person-support apparatus frame, the siderail assembly comprising:
• a siderail;
• a drop surface configured to be raised and lowered relative to a support deck of the person-support apparatus so as to widen or narrow a width of the support deck;
• a siderail adjustment mechanism having a rail end and a frame end;
• and
• wherein:
• the drop surface is removably attached to the siderail;
• the rail end of the siderail adjustment mechanism is pivotally coupled to the siderail;
• the frame end of the siderail adjustment mechanism is pivotable relative to the person-support apparatus frame such that pivoting the siderail adjustment mechanism moves the siderail assembly between a raised position and a lowered position;
• and
• when the siderail assembly is in the raised position, the drop surface fits within the notch to fill an empty space of the notch that is present when the siderail assembly is in the lowered position.

A person-support apparatus comprising:

• a frame;
• a deck supported by the frame and configured to support a person lying on a mattress on the deck, the mattress defining a notch along a length of the mattress, wherein the notch comprises a bottom and a width, the bottom is narrower than the width;
• a siderail positioned at the side of the deck;
• a siderail adjustment mechanism configured to move the siderail upwardly and downwardly relative to the deck;
• and
• wherein:
• the deck comprises a drop section adjacent the siderail and configured to be raised or lowered relative to remainder of the deck, so as to widen or narrow a width of the deck, such that the remainder of the deck is configured to support the person and the drop section to no longer support the person;
• and
• when the siderail assembly is in the raised position, the drop section fits within the notch to fill an empty space of the notch that is present when the siderail assembly is in the lowered position.
