     Referring to  FIGS.  1 - 12 B , reference numeral  10  generally designates a patient support apparatus that includes a frame  14  that has a head portion  18 . The frame  14  includes a recessed edge  22  in the head portion  18 . The recessed edge  22  defines a space  24 . Handles  26 ,  28  are pivotally coupled to the frame  14  proximate the head portion  18 . Each handle  26 ,  28  is adjustable between a raised position  30  and a lowered position  34 . An elongate support member, such as an intravenous (IV) pole  38 , is pivotally coupled to the frame  14  proximate the head portion  18 . The IV pole  38  is adjustable between a stowed position  42  and a deployed position  46 . A cover  50  is coupled to the frame  14  and aligns with the frame  14  to define the recessed edge  22 . 
     With reference to  FIG.  1   , the illustrated patient support apparatus  10  is configured as a hospital bed or other medical bed. The patient support apparatus  10  includes the frame  14 , which generally includes a base frame  14 A and an upper frame  14 B. The base frame  14 A is supported on casters or wheels  54  that engage with an underlying floor surface. The wheels  54  are coupled to the frame  14  via an axle. The wheels  54  may be configured to rotate in a power drive mode in order to propel the patient support apparatus  10  for transportation by a caregiver, medical professional, or other users. 
     The base frame  14 A supports the upper frame  14 B. The upper frame  14 B is operable between raised, lowered, and tilted positions relative to the base frame  14 A. The upper frame  14 B of the patient support apparatus  10  includes a support surface  62 , and a support member, such as a mattress  66 , which is disposed on the support surface  62  and supported by the upper frame  14 B. It is within the scope of the disclosure that the patient support apparatus  10  may be any patient support apparatus  10  known in the art such as, for example, a stretcher, a medical bed, a bed frame, a mattress, other types of beds, surgical tables, examination tables, or any suitable structure for supporting a patient or occupant. 
     As illustrated in  FIG.  1   , the frame  14  of the patient support apparatus  10  includes the head portion  18  and a foot portion  70 . The head portion  18  and the foot portion  70  of the upper frame  14 B may be independently raised, lowered, or tilted relative to the base frame  14 A. The patient support apparatus  10  includes a footboard  74  selectively disposed at the foot portion  70  and a headboard  78  selectively disposed at the head portion  18 . In the illustrated configuration, the patient support apparatus  10  includes a pair of head siderail assemblies  82  and a pair of foot siderail assemblies  86 . The head and foot siderail assemblies  82 ,  86  may be raised and lowered relative to the frame  14 . 
     In various examples, a user interface  88  is coupled to an external side of at least one siderail of the head and foot siderail assemblies  82 ,  86 . The user interface  88  is configured to accept a user input in order to control functions of the mattress  66  or the patient support apparatus  10 . Specifically, the user interface  88  receives commands relating to patient comfort or patient care while the patient is positioned on the patient support apparatus  10 . It is contemplated that the user interface  88  may be coupled to an internal side of at least one siderail of the head or foot siderail assemblies  82 ,  86  to allow the patient on the patient support apparatus  10  to control functions of the mattress  66  or the patient support apparatus  10 . For example, the patient may call or alert medical professionals or caregivers through the user interface  88 . Additionally or alternatively, the user interface  88  may be coupled to the footboard  74  or the headboard  78 . It is contemplated that the user interface  88  may be coupled to any suitable component of the patient support apparatus  10  for access by a patient, a caregiver, or other users. 
     Referring still to  FIG.  1    as well as  FIG.  2   , the patient support apparatus  10  may include various mattress function technologies, such as a microclimate management (MCM) system  90 . The MCM system  90  may address shear, friction, pressure, and moisture properties of the mattress  66  in order to optimize patient comfort and to keep the skin of a patient cool and dry, which may aid in the prevention of complications in patient recovery, such as wound prevention. The MCM system  90  may automatically make adjustments based on predetermined therapy functions or manually make adjustments based on user input commands received from the user interface  88 . The patient support apparatus  10  may further include a pneumatic system  92  that provides air for the operation of the MCM system  90 . Furthermore, the pneumatic system  92  may control airflow in and out of various air bladders or cells of the mattress  66 . In some examples, an MCM system status floor indicator may be projected as an image onto the floor surface from a projector  94  coupled with the foot portion  70  of the patient support apparatus  10  to indicate whether the MCM system  90  is on or off, and in what state the MCM system  90  is operating. 
     The patient support apparatus  10  generally includes a controller  96  having a processor  98 , a memory  100 , and other control circuitry. Instructions or routines  102  are stored in the memory  100  and executable by the processor  98 . The controller  96  is in communication with various aspects of the patient support apparatus  10  to communicate control signals, including, for example, the MCM system  90  and a motorized unit  104 . The motorized unit  104  is operably coupled with a drive system  106  connected with the frame  14 . In various aspects, the frame  14  may be operable between raised, lowered, and tilted positions. At least one of the handles  26 ,  28  can include transport controls  108  for operating the motorized unit  104 . The caregiver or other medical professional can input a command through the transport controls  108 , which may be communicated to the controller  96 . Specifically, the transport controls  108  receive commands relating to braking, speed, direction, or other aspects of transporting the patient support apparatus  10 . The transport controls  108  on the handles  26 ,  28  provide more convenient control during transportation of the patient support apparatus  10 . The controller  96  may send a corresponding signal to control the patient support apparatus  10  in response to the command. 
     With reference still to  FIGS.  1  and  2    as well as  FIG.  3   , the head portion  18  of the frame  14  extends beyond a periphery  110  of the mattress  66 . The head portion  18  is configured to provide an interface between the frame  14  and the handles  26 ,  28 . In some examples, a protective shroud may be placed over portions of the frame  14 . The protective shroud may, for example, be positioned between the mattress  66  and the frame  14 . 
     An outer edge  112  of the head portion  18  of the frame  14  generally includes the recessed edge  22  configured to provide additional access to a head area of the patient on the patient support apparatus  10 . The recessed edge  22  is generally defined in a central area of the head portion  18  of the frame  14 . In various examples, the recessed edge  22  is defined between outwardly extending side projections  114 ,  116  of the frame  14 . The side projections  114 ,  116  extend laterally outwards from the sides of the frame  14 , as well as away from the periphery  110  of the mattress  66  to at least partially define a depth of the recessed edge  22 . The side projections  114 ,  116  each define an opening  118 , which may be configured to hold or store medical supplies, such as, for example, an oxygen tank. 
     The recessed edge  22  is generally trapezoidal-shaped. A rear wall  120  of the recessed edge  22  is disposed inboard of the outer edge  112  of the side projections  114 ,  116 . Opposing sidewalls  122 ,  124  of the recessed edge  22  extend between the rear wall  120  and the outer edge  112  on the side projections  114 ,  116 . The sidewalls  122 ,  124  extend at oblique angles from the rear wall  120 . In the illustrated example, the sidewalls  122 ,  124  extend at obtuse angles from the rear wall  120 , away from one another. Accordingly, a width of the space  24  defined by the recessed edge  22  may be greater further from the mattress  66  relative to proximate the mattress  66  (e.g., adjacent the rear wall  120 ). It is also contemplated that the recessed edge  22  may define any practicable shape and/or size for providing the caregiver additional access to the occupant on the patient support apparatus  10 . The space  24  is wider adjacent to the outer edge  112  on the side projections  114 ,  116  relative to the width of the space  24  adjacent to the rear wall  120  of the recessed edge  22  may be advantageous for providing comfort to a caregiver moving within the space  24 . The opposing sidewalls  122 ,  124  extending at oblique or obtuse angles may reduce sharp corners where a caregiver moves around to access the patient on the patient support apparatus  10 . 
     Referring to  FIGS.  3  and  4   , the patient support apparatus  10  generally includes two handles  26 ,  28 , however it is contemplated that the patient support apparatus  10  may include a single handle  26 . In the illustrated example, the handles  26 ,  28  are configured as transport handles  26 ,  28 . Each handle  26 ,  28  is configured to rotate downward into abutment or close proximity to the head portion  18  of the frame  14 . Each handle  26 ,  28  includes a base  126  that is secured to the head portion  18 . The base  126  of the handle  26  is secured to one side projection  114  of the frame  14 , and the base  126  of the handle  28  is secured to the other side projection  116 . It is contemplated that the handles  26 ,  28  may be secured to any practicable location on the head portion  18  of the frame  14  without departing from the teaching herein. 
     The bases  126  are pivotally coupled to proximal ends  128  of shafts  130  of the handles  26 ,  28 , respectively. Each handle  26 ,  28  is operable to rotate or pivot inwardly from the raised position  30  to the lowered position  34 . As illustrated in  FIG.  3   , when in the lowered position  34 , the shafts  130  of the handles  26 ,  28  are abutting or in close proximity to the head portion  18 . As illustrated in  FIG.  4   , when in the raised position  30 , the shafts  130  extend generally vertically, normal to a longitudinal extent of the frame  14 . Stated differently, when in the raised position  30 , the handles  26 ,  28  extend substantially perpendicular to the support surface  62  of the frame  14 , and when in the lowered position  34 , the handles  26 ,  28  extend substantially parallel to the support surface  62  of the frame  14 . The handles  26 ,  28  may be in the form of a metal tube but are not limited to such constructions. 
     According to various aspects, a protective cover  132  is disposed proximate the proximal end  128  of each handle  26 ,  28 , which generally covers a mechanical or rotational joint configured to fold, or collapse, the handles  26 ,  28  from the raised position  30 . The protective cover  132  may be configured as polymeric bellows. For example, the handles  26 ,  28  may fold, or rotate, at a 90° angle. However, the handles  26 ,  28  may fold to any position between vertical and horizontal. In this way, the handles  26 ,  28  may be stowed on the head portion  18  of the frame  14 . The protective cover  132  may fluidly seal the mechanical joint, such that fluids cannot come into contact with the mechanical joint. 
     Additional space  24  provided by the recessed edge  22  may not be substantially impinged by the handles  26 ,  28 . The handles  26 ,  28  rotate inwardly, at least partially toward the mattress  66  and partially toward one another (e.g., the opposing handle). The handles  26 ,  28  rotate inwardly toward the mattress  66  at an angle (e.g., an inboard angle) a in a range of from about 10° to about 30° relative to a lateral axis a extending between the two handles  26 ,  28  and parallel to the rear wall  120  of the recessed edge  22 . In a non-limiting example, the handles  26 ,  28  may extend at an angle α of about 19°, extending inboard relative to the frame  14 . Once again, the handles  26 ,  28  do not substantially impinge on the space  24  provided by the recessed edge  22  so that the caregiver has additional space to access the patient on the patient support apparatus  10 . In addition, it is understood that when in the raised position  30 , each handle  26  affords a substantial width W 1  of the space  24  that is equal to or greater than a width W 2  of the space  24  defined by the recessed edge  22  of the head portion  18 . Accordingly, the caregiver has increased access to the patient on the patient support apparatus  10  when each handle  26 ,  28  is in the raised position  30  and in the lowered position  34 . 
     Referring still to  FIGS.  3  and  4   , the shape of the shafts  130  may prevent the handles  26 ,  28  from substantially impinging the space  24  provided by the recessed edge  22 . The shaft  130  of each handle  26 ,  28  includes a proximal portion  134 , a distal portion  136 , and a connecting portion  138 . The proximal and distal portions  134 ,  136  of the shafts  130  are spaced-apart and offset from one another by the connecting portion  138 . Although offset, the proximal and distal portions  134 ,  136  are generally substantially parallel to one another, with the connecting portion  138  extending at an angle therebetween. 
     The proximal portion  134  of each shaft  130  extends into the connecting portion  138  via a proximal bend  140 , and the connecting portion  138  extends into the distal portion  136  via a distal bend  142 . The proximal and distal bends  140 ,  142  of the shafts  130  may be substantially the same shape or define substantially similar angles between adjacent portions of the shafts  130 . In the illustrated configuration, each of the proximal and distal bends  140 ,  142  define an obtuse angle between adjacent portions of the shafts  130 . Accordingly, the obtuse angles are defined between the proximal portion  134  and the connecting portion  138 , as well as between the connecting portion  138  and the distal portion  136 . In this way, each handle  26 ,  28  generally defines an elongated Z-shape. 
     The obtuse angle formed by the proximal bend  140  is generally a mirror image of the obtuse angle defined by the distal bend  142 . As such, the proximal and distal portions  134 ,  136  are positioned in the offset, parallel configuration. As illustrated, the proximal and distal bends  140 ,  142  each have an arcuate shape. However, it is contemplated that the proximal and distal bends  140 ,  142  may be a variety of shapes, such as, for example, curved, sloped, or the like. It is also contemplated that the proximal and distal bends  140 ,  142  may not be substantially similar in shape or may not define substantially similar angles. In such examples, the proximal and distal portions  134 ,  136  may not be substantially parallel. 
     Referring still to  FIGS.  3  and  4   , the handles  26 ,  28  extend substantially over the frame  14  adjacent to the recessed edge  22  when in the lowered position  34 . When in the lowered position  34 , the handles  26 ,  28  extend at least partially over the IV pole  38  when the IV pole  38  is in the stowed position  42 . The proximal and distal bends  140 ,  142 , as well as the connecting portion  138 , are generally disposed over the IV pole  38 . Accordingly, the handles  26 ,  28  may be stacked over the IV pole  38  for storing the handles  26 ,  28  and the IV pole  38 . Additionally, the stacked configuration of the handles  26 ,  28  and the IV pole  38  generally prevent the handles  26 ,  28  and the IV pole  38  from substantially impinging the space  24  defined by the recessed edge  22 , and may increase access for the caregiver to the occupant on the patient support apparatus  10 . Moreover, the handles  26 ,  28  may be stored in the lowered position  34  when the patient support apparatus  10  is stationary (e.g., not in transport), allowing increased access to the patient by the caregiver. The configuration of the handles  26 ,  28  with the angled connecting portion  138  may be advantageous for storing the handles  26 ,  28  over the frame  14 , as well as for storing the patient support apparatus  10 . 
     According to various aspects, a distance between a distal end  146  of each shaft  130  and the connecting portion  138  is less than the distance between the proximal end  128  and the connecting portion  138 . Accordingly, the length of the proximal portion  134  is less than the length of the distal portion  136 , such that the proximal and distal bends  140 ,  142  are disposed closer to a grip  154  than the protective cover  132 . In this configuration, the proximal portion  134  of each of the shafts  130  extends along the respective sidewall  122 ,  124 , and partially along the rear wall  120 . The connecting portion  138  is disposed substantially along or inboard of the rear wall  120  of the recessed edge  22 . This configuration also prevents the handles  26 ,  28  from substantially impinging the space  24  defined by the recessed edge  22  when the handles  26 ,  28  are in the lowered position  34 . 
     Referring still to  FIGS.  3  and  4   , each handle  26 ,  28  includes the grip  154  that extends from the distal end  146  of the shaft  130 , or alternatively, may be disposed over the distal end  146  of the shaft  130 . In various examples, the grips  154  extend upwardly from the shafts  130  at a n angle in a range of from about 5° to about 25° relative to a longitudinal axis of the respective shaft  130 . In this way, the grips  154  of each of the handles  26 ,  28  may be angled toward one another when the handles  26 ,  28  are in the raised position  30 . Additionally or alternatively, the grips  154  of the handles  26 ,  28  may pivot or rotate relative to the shafts  130  to allow the user or caregiver to position the grips  154  at various angles for use or storage. It is also contemplated that the grip  154  of each handle  26 ,  28  may extend along the longitudinal axis of the shaft  130 , such that the grip  154  is a continuous linear extension of the distal end  146 . The grips  154  may include one or more indents  158  to accommodate a hand of the user or caregiver. The indents  158  may define outer boundaries for the hand of the caregiver or features to form a more ergonomic grasp for the caregiver. It will be understood that the grip  154  on each handle  26 ,  28  may include a variety of features, including the controls  108  to operate the motorized unit  104  configured to move the patient support apparatus  10  in a forward, rearward, or sideways direction or adjust the upper frame  14 B relative to the base frame  14 A. 
     Each grip  154  may be in a fixed position relative to the shaft  130 , or alternatively, the grips  154  may be adjustable relative to the shafts  130  to allow the frame  14  to accommodate different user heights. The user or caregiver may grasp the grip  154  at a comfortable position without raising or lowering the handles  26 ,  28  or the upper frame  14 B. The grips  154  may be made of a polymeric, rubber-like material, which may include a thermoplastic elastomer (TPE). In some examples, the grip  154  is made of Santoprene™, which is a thermoplastic vulcanizate (TPV). It may be beneficial for the caregiver to push the handles  26 ,  28 , such that the forearms of the caregiver may be generally parallel with the floor, which may include a position slightly below an elbow. Therefore, caregivers of different heights may benefit from positioning their hands on different locations of the handles  26 ,  28  or have the grips  154  at different angles in order to form a more ergonomic posture for pushing the patient support apparatus  10 . As such, the grips  154  may be positioned on the handles  26 ,  28  and may be configured to accommodate more than one hand position or grip point. 
     Referring to  FIGS.  5  and  6   , the IV pole  38  is rotatably or pivotally coupled to the head portion  18  of the frame  14  on or proximate the side projection  116 . The IV pole  38  may be coupled to the head portion  18  proximate either of the side projections  114 ,  116  or elsewhere on the frame  14 . As illustrated, the elongate support member is configured as the IV pole  38 , but may be configured to support other medical equipment or supplies without departing from the teachings herein. The IV pole  38  is operable between the stowed position  42 , as illustrated in  FIG.  5   , and the deployed position  46 , as illustrated in  FIG.  6   . The IV pole  38  may be in the form of a metal tube or shaft but is not limited to such constructions. 
     The IV pole  38  is configured to rotate downward into abutment or close proximity to the head portion  18  of the frame  14 . The IV pole  38  includes a support base  162  that is secured to the head portion  18 . The support base  162  is pivotally coupled to a proximal end  166  of the IV pole  38 . The protective cover  132  ( FIG.  1   ) in the form of the polymeric bellows may be disposed on a proximal portion  170  of the IV pole  38  over a pivoting or rotation assembly (e.g., a hinge, a ball-and-socket, etc.) coupling the IV pole  38  with the support base  162 . The IV pole  38  is operable to rotate, or pivot, between the deployed position  46 , where the IV pole  38  extends generally vertically, normal to a longitudinal extent of the frame  14 , and the stowed position  42 , where the IV pole  38  abuts or is in close proximity to the head portion  18 , such that the IV pole  38  extends generally horizontally. 
     When in the stowed position  42 , the IV pole  38  extends laterally across the support surface  62  of the frame  14  adjacent to, and inboard of, the rear wall  120  of the recessed edge  22 . As illustrated, the IV pole  38  is disposed along and aligned with the rear wall  120 . Accordingly, the IV pole  38  is disposed substantially over the frame  14 . It is contemplated that the IV pole  38  may extend in another direction along the head portion  18  of the frame  14 . In this way, the IV pole  38  does not substantially impinge the space  24  defined by the recessed edge  22  when in the stowed position  42  and when in the deployed position  46 . As such, the positioning of the IV pole  38  relative to the recessed edge  22  provides increased access to the patient on the patient support apparatus  10 . 
     Referring still to  FIGS.  5  and  6   , a length of the IV pole  38  may be adjustable. The IV pole  38  may telescopically expand and retract or otherwise be adjustable between expanded and retracted positions. As illustrated in  FIG.  5   , a distal portion  174  of the IV pole  38  extends at least partially across the opening  118  of the opposing side projections  114  relative to the position of the support base  162 . An adjustable length may be advantageous for shortening the IV pole  38  when in the stowed position  42 , such that the IV pole  38  may not substantially interfere with the opening  118  of the opposing side projection  116  of the frame  14 . This may be further advantageous for storing the IV pole  38  in the stowed position  42  while storing medical supplies (e.g., oxygen tanks) in the openings  118  defined by the side projections  114 ,  116  of the frame  14 . Additionally, the adjustable length of the IV pole  38  may prevent the IV pole  38  from extending beyond the outer edge  112  of the frame  14 . The IV pole  38  may include a latch to retain the IV pole  38  at the selected length. In addition, the distal portion  174  of the IV pole  38  may include a hook  186  or similar structures, for retaining medical supplies (e.g., an IV bag). 
     According to various aspects, both the handles  26 ,  28  and the IV pole  38  may include a locking feature. The locking feature may retain the handles  26 ,  28  in the raised position  30  or the lowered position  34  and the IV pole  38  in the stowed position  42  or the deployed position  46 . In this way, the handles  26 ,  28  and the IV pole  38  may not unintentionally move between positions during transportation of the patient support apparatus  10 . 
     The space  24  defined by the recessed edge  22  provides increased access to the patient on the patient support apparatus  10 . In addition, the headboard  78  may be removed by the caregiver to further increase access to the patient on the patient support apparatus  10 . Stated differently, the headboard  78  may be adjusted between an engaged position  194 , as illustrated in  FIG.  6   , and a disengaged position  198 , as best illustrated in  FIG.  4   . In various examples, when in the engaged position  194 , the headboard  78  is coupled to the head portion  18  of the frame  14  via retaining brackets  202 . The headboard  78  may slidably engage the retaining brackets  202 . The caregiver may slide the headboard  78  into the retaining brackets  202  to couple the headboard  78  to the frame  14  and slide the headboard  78  away from the retaining brackets  202  to remove the headboard  78 . In the disengaged position  198 , the headboard  78  may be removed from the patient support apparatus  10 . 
     Referring still to  FIG.  7   , the patient support apparatus  10  includes multiple lift arms  206  disposed between the base frame  14 A and the upper frame  14 B. It is contemplated that the patient support apparatus  10  may include a single lift arm  206  without departing from the teachings herein. The lift arms  206  are operably coupled to the base frame  14 A and the upper frame  14 B and operate to raise, lower, and tilt the upper frame  14 B relative to the base frame  14 A. Each lift arm  206  includes an upper joint  210  proximate to the upper frame  14 B and a lower joint  214  proximate to the base frame  14 A. The upper and lower joints  210 ,  214  provide a connection point and a point of rotation of the lift arms  206  relative to the base frame  14 A and the upper frame  14 B, respectively. In the illustrated configuration, the upper frame  14 B includes brackets  216  that define the upper joint  210 , and the base frame  14 A integrally defines the lower joint  214 . However, any practicable configuration (e.g., the brackets  216 , integrally defined joints  210 ,  214 , etc.) may be utilized for pivotally coupling the lift arms  206  to the base frame  14 A and the upper frame  14 B. The lift arms  206  include metal materials, metal alloy materials, or other similar materials. 
     Referring still to  FIG.  7    as well as  FIG.  8   , the lift arms  206  may extend beyond the rear wall  120  of the frame  14  and impinge the space  24  defined by the recessed edge  22 . The rear wall  120  and the sidewalls  122 ,  124  of the recessed edge  22  define the space  24 . The space  24  extends vertically from the floor surface to a ceiling surface. Accordingly, the space  24  accommodates the caregiver when the caregiver is adjacent the recessed edge  22  and is not limited to the space  24  directly between the sidewalls  122 ,  124 . In this way, the lift arms  206  extending into the space  24  below the upper frame  14 B may interfere with the caregiver accessing the patient on the patient support apparatus  10 . Moreover, the lift arms  206  may limit the ability of the caregiver to move around within the space  24  defined by the recessed edge  22  to access the patient on the patient support apparatus  10 . The upper joint  210  may extend different distances beyond the rear wall  120  depending on the angle of the lift arms  206  as determined by the position of the upper frame  14 B relative to the base frame  14 A. Legs of the caregiver or other user may contact the lift arms  206  or the upper joints  210  that protrude beyond the rear wall  120 . As such, the cover  50  may be coupled to the frame  14  and extend outward, into the space  24  defined by the recessed edge  22 , and vertically over the lift arms  206  to prevent contact between the caregiver and the lift arms  206 . 
     Referring to  FIG.  9   , the cover  50  is disposed on the head portion  18  of the frame  14  and generally aligns with the frame  14  to at least partially define the space  24 . The cover  50  may extend over the entire, or a substantial portion, of the head portion  18  of the frame  14 , or alternatively, may be coupled directly to the outer edge  112  of the frame  14 . The cover  50  may be a single component or, alternatively, may be multiple components disposed on the head portion  18  of the frame  14 . According to various aspects, the cover  50  aligns with the rear wall  120  and extends from the side projections  114 ,  116 , over the sidewalls  122 ,  124  of the recessed edge  22 , and into the space  24  defined by the recessed edge  22 . A rear wall  218  of the cover  50  vertically aligns with the rear wall  120  of the recessed edge  22 , and sides  220 ,  222  of the cover  50  are spaced-apart from the sidewalls  122 ,  124  of the recessed edge  22 . Accordingly, the cover  50  narrows the space  24  defined by the recessed edge  22  to a width W 3  but does not substantially reduce the depth of the space  24  (e.g., the depth of the space  24  defined by the recessed edge  22  is maintained). 
     From a top view of the frame  14 , the cover  50  substantially obscures the lift arms  206  from view. The sides  220 ,  222  disposed within the space  24  defined by the recessed edge  22  are vertically aligned with the portions of the lift arms  206  that extend into the space  24 . The cover  50  may prevent the caregiver from moving within the space  24  in a way that would cause the caregiver to contact the lift arms  206 . The cover  50  may prevent or impede the caregiver from contacting the lift arms  206 . 
     Additionally or alternatively, the proximal portion  134  of the handles  26 ,  28  may extend at least partially into or through the space  24  defined by the recessed edge  22  when in the lowered position  34  adjacent to the intersections between the sidewalls  122 ,  124  and the rear wall  120 , respectively, as best illustrated in  FIG.  8   . The addition of the cover  50  to the head portion  18  of the frame  14  results in the proximal portions  134  of the handles  26 ,  28  extending over the cover  50 , thereby reducing the interference of the handles  26 ,  28  within the space  24  defined by the recessed edge  22 . The cover  50  narrows the width W 3  of the space  24  defined by the recessed edge  22 , such that the lift arms  206  and the proximal portions  134  of the handles  26 ,  28  may not substantially impinge the space  24  defined by the recessed edge  22 . This configuration may provide for increased access for the caregiver at the head portion  18  of the patient support apparatus  10  while reducing interference from the handles  26 ,  28  or the lift arms  206 . 
     Referring to  FIGS.  10 - 11 B , in various examples, bumpers  224  are coupled to one or more of the lift arms  206 . As illustrated, the bumpers  224  are coupled to the upper joints  210  of the lift arms  206  proximate the head portion  18  of the patient support apparatus  10 , which may be the portions of the lift arms  206  that the caregiver is most likely to contact in the space  24  defined by the recessed edge  22 . Specifically, the bumpers  224  are constructed of a pliable material with shock-absorbing properties. The bumpers  224  prevent the caregiver from directly striking the lift arms  206  while moving in the space  24  defined by the recessed edge  22 . If the caregiver contacts the patient support apparatus  10  while providing treatment to the patient, the caregiver generally contacts the bumpers  224 , which minimizes the potential for injurious contact that may be caused by direct contact with the lift arms  206 . It is also contemplated that the bumpers  224  may also be coupled to other lift arms  206  (e.g., proximate the foot portion  70 ) or in other locations on the lift arms  206  (e.g., on the lower joints  214 ) of the patient support apparatus  10 . The bumpers  224  may be advantageous for protecting the upper joints  210  of the lift arms  206 , as well as for protecting the caregiver from directly contacting the lift arms  206 . The bumpers  224  may include low durometer materials, such as, for example, plastics, urethanes, rubbers, or other similar materials. In some examples, the bumpers  224  may include Santoprene™. 
     The bumpers  224  generally have a substantially rectangular or trapezoidal shape, however, the bumpers  224  may have any practicable shape that does not substantially interfere with the articulation of the upper and lower joints  210 ,  214 . Sides  226  of the bumpers  224  each define a protrusion  230 , such that the shape of the bumpers  224  flares outward at one end. The protrusions  230  may be substantially similar, such that the bumpers  224  are symmetrical. The protrusions  230  are generally positioned over and cover pivoting fasteners of the lift arms  206 . As best shown in  FIG.  11 B , the protrusions  230  are hollow, such that the pivoting fasteners of the lift arms  206  are disposed within the protrusions  230  and the bumpers  224  do not substantially interfere with the movement of the pivoting fasteners or the lift arms  206 . 
     Additionally or alternatively, the bumpers  224  define grooves  234  proximate the protrusions  230 . The grooves  234  generally accommodate rotation and other movements of the bumpers  224  and the lift arms  206  as the lift arms  206  raise, lower, or tilt the upper frame  14 B. The protrusions  230  and the grooves  234  may be advantageous for providing greater flexibility and range of motion to the bumpers  224  to cover the upper or lower joints  210 ,  214  while the lift arms  206  are in motion or in different positions. 
     As best illustrated in  FIG.  11 B , an interior surface  238  of the bumpers  224  defines snap features  242  to couple the bumpers  224  to the lift arms  206 . Two snap features  242  are coupled to the bumper  224 , however, any number of snap features  242  may be used to couple the bumpers  224  to the lift arms  206 . The snap features  242  selectively engage with corresponding apertures or grooves in the lift arms  206 . In this way, the bumpers  224  may be quickly added and removed from the lift arms  206  by the caregiver or other user. In another example, the bumpers  224  may be mechanically fastened to the lift arms  206 . The bumpers  224  may be coupled via bolts, screws, pins, or other similar mechanical fasteners. In some examples, the mechanical fasteners may be Christmas Tree™ fasteners or other push fasteners, shoulder screws, shoulder bolts, separate snap features, or self-tapping shoulder screws. Additionally or alternatively, the bumpers  224  may be adhered to the lift arms  216 . The bumpers  224  may be used in combination with or independently of the cover  50 . 
     Referring to  FIGS.  12 A and  12 B , the patient support apparatus  10  may include asymmetrical bumpers  250 ,  252  operably coupled to the lift arms  206 . The bumpers  250 ,  252  are generally mirror images of one another and disposed on opposing sides of the patient support apparatus  10  (e.g., left and right bumpers  250 ,  252 ). Each bumper  250 ,  252  includes protrusions  254 ,  256  extending from the sides  226  adjacent to one of the ends. The protrusions  254 ,  256  are hollow to accommodate a pivoting fastener of the lift arms  206 . The protrusion  254  generally has a depth less than a depth of the protrusion  256 . The protrusions  254 ,  256  may accommodate pivoting fasteners of different sizes. The different depths of the protrusions  254 ,  256  may prevent the bumpers  250 ,  252  from impeding the articulation of the lift arms  206  between different positions. The bumpers  250 ,  252  also define the grooves  234  proximate the protrusions  254 ,  256 . The grooves  234  accommodate rotation and other movements of the bumpers  250 ,  254  and the lift arms  206  as the lift arms  206  raise, lower, or tilt the upper frame  14 B. The bumpers  250 ,  252  may be used in combination with or independently of the cover  50 . 
     The bumpers  250 ,  252  may be coupled to the lift arms  206  via a separate snap feature or other similar fasteners. Each bumper  250 ,  252  defines apertures  258  for receiving the snap feature. The apertures  258  may each be defined in a recessed portion  260 . The recessed portion  260  may be advantageous for accommodating the snap feature. Accordingly, when the bumpers  250 ,  252  are engaged with the lift arms  206  via the snap features, the snap features are flush with an outer surface of the bumpers  250 ,  252 . The snap feature being flush with the outer surface of the bumpers  250 ,  252  prevents injurious contact between the snap feature and the caregiver moving in the space  24  defined by the recessed edge  22 . Accordingly, if the caregiver contacts the patient support apparatus  10 , the caregiver may directly contact the bumpers  250 ,  252 . Each bumper  250 ,  252  may include any practicable number of apertures  258  and recessed portions  260  for coupling the bumpers  250 ,  252  to the lift arms  206 . 
     Use of the present disclosure may provide for a variety of advantages. For example, the head portion  18  that includes the recessed edge  22  provides additional or increased access to the patient on the patient support apparatus  10 . Additionally, the handles  26 ,  28  may not substantially impinge with the space  24  defined by the recessed edge  22  when the handles  26 ,  28  are in the raised or lowered position  30 ,  34 . The shape or rotation of the handles  26 ,  28  allows the handles  26 ,  28  to be disposed over the frame  14  when in the lowered position  34  and reduce interference of the handles  26 ,  28  with the caregiver moving within the space  24  defined by the recessed edge  22 . Further, the placement of the IV pole  38  reduces or minimizes interference of the IV pole  38  in the space  24  defined by the recessed edge  22  when the IV pole  38  is in the deployed or stowed position  42 ,  46 . Moreover, the cover  50  coupled to the head portion  18  of the frame  14  extends over the lift arms  206  to reduce direct contact between the caregiver and the lift arms  206 . Additionally, the bumpers  224  coupled to the lift arms  206  reduce direct contact between the caregiver and the lift arms  206  or the upper joints  210 . Additional benefits or advantages of using this device may also be realized and/or achieved.
