Title: Retractable step and side bar assembly for raised vehicle

Description:
INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS 
     Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57. 
     BACKGROUND 
     Field 
     This disclosure relates generally to a retractable step and side bar assembly for a raised vehicle. 
     Description of the Related Art 
     Many types of vehicles, including sport utility vehicles (e.g. JEEP® brand vehicles), pickup trucks, and vans, are raised off the ground farther than normal passenger automobiles. The increased height of the floor of the passenger cab from the ground makes it difficult to enter and exit these vehicles. 
     In addition, if the vehicles are driven over rough terrain, their lower body panels and door panels are susceptible to being scratched, dented, or otherwise damaged by rocks or other ground debris. To address this issue, the nerf bars or rock rails can function to protect the body of the vehicles from being damaged from below. Moreover, nerf bars can be mounted to the vehicle to provide a stepping surface to assist the driver and passengers in entering and exiting these vehicles. 
     SUMMARY 
     Typically, running boards, side bars, and/or nerf bars are used to help a user access a vehicle. Further, these side bars can provide for enhanced aesthetics of the vehicle. However, the side bars can have significant limitations as side bars sit too high because of necessary ground and side clearance. This creates a stepping platform positioned too high and too inboard, thus creating an awkward ingress/egress for a user. That being said, it is desirable to keep the aesthetics of the side bars while still providing ease of access for a user to enter a vehicle. 
     Accordingly, embodiments of the disclosure allow for a user to lower an additional step to a low, functional stepping height to get in and out of the vehicle, yet stow them to the higher position for vehicle operation behind the side bar, creating the necessary ground clearance while also improving the vehicle aesthetics. 
     Moreover, many users enjoy the aesthetics of nerf bars without needing the structural support of the nerf bars. Accordingly, disclosed herein are side bars that can be used as aesthetic replacements for the nerf bars, without requiring the structural support they provide. As disclosed in detail below, they can be used in conjunction with a retractable step to provide for advantageous aesthetics for a raised vehicle while still assisting a user enter and exit the vehicle. 
     One area where standard deployable running boards fall short is on the more extreme vehicles, lifted higher than the typical truck. For such vehicles, it has been recognized that it would be desirable for the step to be deployed even lower than the linkage packaging allows. An embodiment that combines the side bar and vehicle step assembly allows one to stow the boards at an even lower level, without compromising the aesthetics, and desirably also allows the boards to be deployed to a lower level. Simply said, a lower stowed position facilitates a lower deployed position, and doing this in combination with the side bar accomplishes this while still looking good. 
     Disclosed herein are embodiments of a combination side bar and vehicle step assembly, the assembly comprising a side bar configured to be mounted to a vehicle by at least one mounting bracket defining a mounting surface configured to mate with the vehicle and an extendable vehicle step comprising a stepping platform connected to at least one pair of arms, the at least one pair of arms connected to a frame, the frame being connected to the at least one mounting bracket, wherein the extendable vehicle step is movable between a stored and a deployed position, where the vehicle step is in the deployed position below and outboard to the side bar, and when the extendable vehicle step is in the deployed position, the stepping platform is at least partially outboard to the side bar. 
     In some embodiments, when the extendable vehicle step is in the stored position, the stepping platform can be at least partially inboard from the mounting surface.

     DETAILED DESCRIPTION 
     Disclosed herein are combinations of a stepping structure with a side bar, in particular for use on the sides of vehicles. The side bar and step combination can be uniquely formed to provide for a low profile in the retracted position, where the step is minimized exposed below the side bar, while also having significant reach in the deployed position to allow for a user to easily use the step to access the vehicle itself. The combination of the side bar  100  and step  1000 , forming a combination assembly  10 , attached to a vehicle  20  is shown in  FIGS. 1-2 . Further,  FIGS. 3A-B  show the combination assembly  10  in the deployed ( FIG. 3A ) and the stowed ( FIG. 3B ) positions. As shown, the combination assembly  10  advantageously allows for the step  1000  to be partially hidden by the side bar  100  when in the stowed position, improving overall aesthetics of the combination assembly  10 . However, the combination assembly  10  is usable with many other types of vehicles, for example standard cab pickup trucks, extended cab pickup trucks, and sport utility vehicles such as JEEP® brand vehicles, and the type of vehicle does not limit the disclosure. 
     Side Bar 
     As shown in the previous figures, the side bar  100  can be attached to a vehicle  20 , generally on the underside of the frame. The side bar  100  can extend generally away from the frame of the vehicle  20  (e.g., outboard). In some embodiments, the side bar  100  can includes a side bar main body  102  configured for mounting to vehicle  20  via mounting brackets  150 . 
     The mounting bracket  150 , shown in  FIGS. 4A-C , can have a generally c-shaped structure having vehicle attachment portion  152 , a body  153 , and a side bar attachment portion  154 . The vehicle attachment portion  152  can be generally the top of a c-shape structure, while the side bar attachment portion  154  can be generally the bottom. The body  153  can connect the vehicle attachment portion  152  to the side bar attachment portion  154 . 
     The vehicle attachment portion  152  can be generally configured to be located above the side bar attachment portion  154 , and can be located generally on the inside surface of the body of vehicle  20 . The vehicle attachment portion  152  can be configured to be mounted onto the vehicle  20 , such as through an aperture  155 , thereby keeping the mounting bracket  150  in place. The attachment portion  152  can extend perpendicularly from the body  153  to form a flange or mounting surface which can mate with vehicle  20  where the aperture  155  can be located. In some embodiments, the vehicle attachment portion  152  can have a greater thickness than the body  153 . Thus, as discussed, the mounting bracket  150  is configured to mate with portions of the vehicle body (such as shown in  FIG. 13 ) and secure the bracket  150  in both a vertical direction and a horizontal direction with respect to the ground. Thus can be done through the use of fasteners or welding, though the attachment means does not limit the disclosure. It is noted that the configuration of the mounting bracket  150  can be adjusted to match the mounting requirements of a particular vehicle. 
     The side bar attachment portion  154  can be configured to be attached to the side bar  100 . As shown in  FIGS. 4A-C , the side bar attachment portion  154  can be formed by a plurality of surfaces. A base surface  160  can be formed generally on the bottom of the mounting bracket  150 , extending generally perpendicular to the bottom of the body  153 . The base surface  160  can be configured to slide against a surface of the side bar  100 , discussed below, in some embodiments. Further, attached to the base surface  160  and extending upwards and generally parallel to the body  153  is the secondary surface  162 . Extending perpendicular to the front end of the body  153  and secondary surface  162  are a pair for attachment surfaces  164 / 164 ′. These attachment surfaces  164 / 164 ′ can have at least one aperture  166 / 166 ′ extending therethrough. Accordingly, in some embodiments a fastener,  168 , such as a bolt, screw, or other member can extend through the aperture  166 / 166 ′, allowing it to connect to the side bar  100 , as discussed in detail below. In some embodiments, a frame surface  169  can extend away from the body  153  generally parallel to the base surface  160  but in the opposite direction. This surface can be configured to attach to a frame of a vehicle  20 . 
     In some embodiments, a plurality of mounting brackets  150  can be used to attach the side bar  100  to the vehicle  20 . In some embodiments, the mounting brackets  150  can be spaced apart at a particular distance, though the spacing does not limit the disclosure. 
     As shown in  FIGS. 5A-B , side bar main body  102  itself can extend from a first end  101  to a second end  103 . It can be defined by a plurality of walls, each wall having and/or defining outer and inner surfaces that additionally extend from the first to the second end  101 / 103 . As shown in the cross section of  FIG. 6A , the side bar main body  102  can have a front wall  128  and a back wall  130 , which face away from and towards the vehicle  120 , respectively. The back wall  130  can have a channel formed therein to define an opening  106 , described in detail below. Further, below the back wall  130  there can be an extension wall  134  which extends generally perpendicular to the back wall  130  and extends farther than the back wall  130 , and the extension wall  134  can be in contact with the base wall  160  of the mounting bracket  150 , and can help to support the mounting bracket  150 . Further, the side bar main body  102  can have a top wall  136 . As shown in the figures, the top wall  136  can be connected to the front and back walls  130 / 132  by angled or connection walls  138 / 140 . 
     In addition, the side bar main body  102  can have a bottom wall  142  connected to the front wall  130 . Connecting the bottom wall  142  and the back wall  130  are two walls that meet at an approximately perpendicular angle, thus forming a channel  149  on generally the bottom-back side of the side bar main body  102 . The step distal end facing or vertical wall  144  can be generally parallel to the back wall  130  and connected to the bottom wall  130 . The stepping member facing or horizontal wall  146  can extend from the vertical wall  144  to the back wall  130 . In some embodiments, the horizontal wall  146  extends beyond the back wall  130 , thus forming the extension wall  134 . Thus, the vertical and horizontal walls  144 / 146  form the channel  149  in the side bar main body  102 . The channel  149  can be sized and configured to receive at least a portion of the step  200 , as discussed in detail below, thus providing for aesthetic improvements, as well as improved clearance. 
     While a particular shape of the side bar main body  102  is shown and discussed, it will be known that the particular size and dimensions of the side bar main body  102  does not limit the disclosure. Further, the walls disclosed may change shape throughout the length of the side bar main body  102 . 
     In some embodiments, an internal connection wall  148  can be used to strengthen the side bar main body  102 . In some embodiments, the side bar main body  102  is hollow. In some embodiments, the side bar main body  102  is solid and filled/or in with another material. 
     In some embodiments, the side bar main body  102  extends between a first end  101  and a second end  103  and is formed to have a channel-shape defining a longitudinal opening  106  extending at least partially between the first and second ends  101 / 103  of the back wall  130  of the side bar main body  102 . The longitudinal opening  106  can extend partially into the back wall  130  to retain a fastener. In some embodiments, the longitudinal opening  106  can extend the full length of the side bar main body  102 , and thus be open at the first and second ends  101 / 103 . In some embodiments, the longitudinal opening  106  only extends partially along the length of the side bar main body  102 , thereby being closed at either the first or second ends  101 / 103 , or both. As shown in  FIG. 6B , the longitudinal opening  106  can be sized and configured to receive and retain a fastener  168  that protrudes through the apertures  166 / 166 ′ of the mounting bracket  150 . Thus, the side bar  100  can be attached to the mounting bracket  150 . In some embodiments, the fasteners  168  can be configured to be tightened within the longitudinal opening  106 . Therefore, the side bar  100  can be moved with respect to the mounting bracket  150 , and thus vehicle  20 , allowing for the position of the side bar  100  to be adjusted. Accordingly, when the side bar  100  is in the desired position, the fasteners  168  can be tightened, thus stopping motion of the side bar  100  with respect to the mounting bracket  150 . 
     In some embodiments, such as shown in  FIGS. 5A-B , the side bar main body  102  may be provided with a first end cap  120  a connected to the first end  101  of the side bar main body  102  and a second end cap  120  b connected to the second end  103  of the side bar main body  102 . In some embodiments, the end caps  120  a,  120  b (collectively referred to as  120 ) can be mirror images of each other and are shaped to match the cross-sectional profile of the side bar main body  102 . In some embodiments, the end caps  120  may have a greater dimension than the side bar main body  102 , thereby providing end coverings of the channel  149 . In the embodiment shown, the end caps  120  are welded to the side bar main body  102 . However, other connections means are certainly possible, such as the use of fasteners. 
     Referring back to  FIG. 2 , in some embodiments, the side bar  100  length (Lr) can extend at least half of a length of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend at least ¾ of a length of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend at least half of a length of a door (L d1  or L d2 ) on one side of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend at least ¾ of a length of a door (L d1  or L d2 ) on one side of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend at least a length of a door (L d1  or L d2 ) on one side of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend at least half of a length of two doors (Ld) on one side of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend at least ¾ of a length of two doors (Ld) on one side of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend at least a length of two doors (Ld) on one side of the vehicle  20 . In some embodiments, the side bar  100  length (Lr) can extend about 2, 3, 4, 5, 6, 7, or 8 feet. In some embodiments, the side bar  100  length (Lr) can extend at least about 2, 3, 4, 5, 6, 7, or 8 feet. 
     In some embodiments, the side bar main body  102  may be formed from an initially flat sheet, for example a flat sheet of about  11  gauge steel. Other sheet thicknesses may also be used, and the particular thickness does not limit the disclosure. The side bar main body  102  may be formed by other processes as well, for example by stamping, casting, or extrusion, and the particular method of manufacturing does not limit the disclosure. 
     In some embodiments, the side bar  100  may be a modular side bar as discussed in U.S. Pat. App. No. 2015/0091270, hereby incorporated by reference in its entirety. 
     Stepping Structure 
       FIG. 1  additionally illustrates an embodiment of such a vehicle step  1000  that can be used in conjunction with the side bar  100  to form the combination assembly  10 .  FIG. 7  illustrates the vehicle step  1000  in a stowed position. As shown, the vehicle step  1000  can be composed of numerous components, further discussed below, which can allow for translation of the vehicle step  1000  from a stowed position ( FIG. 7 ) through an intermediate position ( FIG. 8 ) and to a deployed position ( FIG. 9 ) and back again, and can help a user to enter and exit a vehicle. In some embodiments, the vehicle step  1000  can be located under a vehicle door, such as the front or back doors, or below the trunk, though the particular location of the vehicle step  1000  is not limiting. In some embodiments, the vehicle step  1000  can move to the deployed position when a vehicle door is opened and move to a stowed position when an open vehicle door is closed. In some embodiments, the vehicle step  1000  can be moved manually. In some embodiments, the vehicle step  1000  can move through the press of a button or activation of a switch, and can operate independently of motion of a vehicle door, such as disclosed in U.S. patent application Ser. No. 14/169,626, published as U.S. 2015/0123374 A1, hereby incorporated by reference in its entirety. 
     As shown, the vehicle step  1000  can contain a stepping platform  1020 . The stepping platform  1020  can extend generally parallel to the ground and can be configured for a user to step on to allow for access into a vehicle. The stepping platform  1020  can be sized to generally receive a user&#39;s foot in some embodiments. Thus, a plurality of different stepping platforms  1020  can be used for different parts of a vehicle. In some embodiments, the stepping platform  1020  can extend along a substantial length of a vehicle, such as to be configured like a bar as shown in  FIG. 2 . Accordingly, in some embodiments only a single stepping platform  1020  is used on each side of the vehicle for the bar-like configuration. In some embodiments, the stepping platform  1020  can be generally the same length as the side bar  100 . In some embodiments, the stepping platform  1020  can have a smaller length than the side bar  100 . In some embodiments, the stepping platform  1020  can have gripping or high friction material on its upper side to help a user enter a vehicle. 
     Referring back to  FIG. 2 , in some embodiments, the stepping platform  1020  length (Ls) can extend at least half of a length of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend at least ¾ of a length of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend at least half of a length of a door (L d1  or L d2 ) on one side of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend at least ¾ of a length of a door (L d1  or L d2 ) on one side of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend at least a length of a door (L d1  or L d2 ) on one side of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend at least half of a length of two doors (Ld) on one side of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend at least ¾ of a length of two doors (Ld) on one side of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend at least a length of two doors (Ld) on one side of the vehicle  20 . In some embodiments, the stepping platform  1020  length (Ls) can extend about 2, 3, 4, 5, 6, 7, or 8 feet. In some embodiments, the stepping platform  1020  length (Ls) can extend at least about 2, 3, 4, 5, 6, 7, or 8 feet. 
     The stepping platform  1020  can connect to a support component  1030 . In some embodiments, the stepping platform  1020  is attached to the support component  1030  so that the stepping platform  1020  and support component  1030  translate and/or rotate as one unit. In some embodiments, the stepping platform  1020  can rotate separately from the support component  1030 . In some embodiments, support component  1030  and stepping platform  1020  can be a single piece. In some embodiments, the stepping platform  1020  can be integrally formed with the support component  1030 . In some embodiments, the two pieces can be attached to one another through, for example, screws, though the particular attachment means does not limit the disclosure. In some embodiments, the support component  1030  can be substantially thinner than the stepping platform  102 , as shown in, for example,  FIG. 2 . 
     A pair of arms  1040 / 1060  can rotatably attach to the support component  1030 , allowing for rotation of the support component  1030 , and thus the stepping platform  1020 . The arms  1040 / 1060  can be attached to the support component  1030  through the rotation axes  1140 . In some embodiments, either one or both of arms  1040 / 1060  can have a stop, which can be used to prevent the vehicle step  1000  from moving outside a desired rotation. The stops can be, for example, rubber to prevent motion of the vehicle step  1000  while preventing scratching or other damage. However, the particular makeup of the stops does not limit the disclosure. In some embodiments, the combination of stepping platform  1020 , support component  1030 , and arms  1040 / 1060  can be known as the stepping fixture. While only two arms are shown, more arms could be used as well. Further, each arm  1040 / 1060  could be broken into different segments that may or may not rotate with respect to each other. In some embodiments, another bar can connect arms  1040 / 1060 . 
     On the opposite end from the support component  1030 , arms  1040 / 1060  can attach to a frame  1080 . The frame  1080  can be attached to the mounting bracket  150  attached the side bar  100 , as discussed above. For example, the frame  1080  may be located approximately at the body  153  of the mounting bracket  150 . Screws  1055  can be used to affix the frame  1080  to the mounting bracket  150 , though the type of fixture does not limit the disclosure and any type of fixture can be used. In some embodiments, a top surface of the frame  1080  can additionally be attached to the bottom of a vehicle frame. 
     By attaching the frame  1080  to the mounting bracket  150 , the frame  1080  can be located below the frame of a vehicle. In some embodiments, the entirety of the frame  1080  is below the frame of the vehicle. In some embodiments, at least about 50, 60, 70, 80, 90, 95, or 99% of the frame  1080  can be located below the frame of the vehicle. By having the frame  1080  located below the frame of the vehicle, it allows for the stepping platform  1020  to have a deployed position that is significantly lower than if the frame  1080  was attached to the frame of the vehicle, while not having to make any extensions to the arms  1040 / 1060 . This allows the vehicle step  1000  to be advantageous for raised vehicles, as the stepping platform  1020  can now be located at a comfortable position relative to the ground for a user to step onto. 
     In some embodiments, the frame  1080  may contain a fastener that is sized and configured to be inserted into the longitudinal opening  106  of the side bar  100 , and can operate in a similar fashion as discussed above with relation to the attachment of the side bar main body  102  to the mounting bracket  150 . Accordingly, the side bar  100  can be translatable with respect to the frame  1080 , and thus the step  1000 . 
     In some embodiments, such as shown in  FIG. 7 , the frame  1080  may extend towards the centerline (e.g., inboard) of the vehicle. Accordingly, the frame  1080  ma extend from an inside surface of the frame of the vehicle  20  towards the opposite inside surface of the frame of the vehicle  20 . The arms  1040 / 1060  can be attached to frame  1080  through the rotation axes  1140 . In some embodiments, the instant center of the vehicle step  1000  can be located within the vehicle step  1000  when the vehicle step  1000  is in the deployed or stowed position, or in both positions. In some embodiments, the instant center of the vehicle step  1000  is not located outside of the vehicle step  1000 . For example, at any given moment, when the vehicle step  1000  is pivoting from one position to another, the stepping platform  1020  can be considered to be pivoting about one point in space (e.g., an “instant center”) within the vehicle step  1000 , as viewed perpendicular to the rotational axes  1140 , such as viewed from the perspective of  FIG. 7 . In some embodiments, this one point could correspond to being within the horizontal dimension of the stepping platform  1020  (corresponding to an x axis in an x-y coordinate system), could correspond to being within vertical dimension of the stepping platform  1020  (corresponding to a y axis in an x-y coordinate system), or could corresponded to being within cross-section of the stepping platform  1020  in both the horizontal and vertical dimension. 
     In some embodiments, when the vehicle step  1000  is in the deployed position as shown in  FIG. 9 , the angle between the stepping platform  1020  and arm  1040  can be obtuse. In some embodiments, the angle between the stepping platform  1020  and arm  1040  can be about 90, 100, 110, 120, 130, 140, 150, 160, or 170°. In some embodiments, the angle between the stepping platform  1020  and arm  1040  can be greater than about 90, 100, 110, 120, 130, 140, 150, 160, or 170°. In some embodiments, the angle between the stepping platform  1020  and arm  1040  can be less than about 100, 110, 120, 130, 140, 150, 160, 170, or 180°. 
     In some embodiments, when the vehicle step  1000  is in the deployed position as shown in  FIG. 9 , the angle between the stepping platform  1020  and arm  1060  can be obtuse. In some embodiments, the angle between the stepping platform  1020  and arm  1060  can be about 90, 100, 110, 120, 130, 140, 150, 160, or 170°. In some embodiments, the angle between the stepping platform  1020  and arm  1060  can be greater than about 90, 100, 110, 120, 130, 140, 150, 160, or 170°. In some embodiments, the angle between the stepping platform  1020  and arm  1060  can be less than about 100, 110, 120, 130, 140, 150, 160, 170, or 180°. 
       FIG. 10  illustrates an exploded viewpoint of an embodiment of a vehicle step  1000 , illustrates an example of how components of the vehicle step  1000  can fit together. 
       FIG. 11  illustrates an embodiments of a vehicle step  1000  in an intermediate position, in particular to more easily show dimensions for some of the different parts of the vehicle step  1000 . 
     In some embodiments, the length (Y) of arm  1040  is the same as the length (X) of arm  1060 . In some embodiments, the length (Y) of arm  1040  is different than the length (X) of arm  1060 . In some embodiments, the length (Y) of arm  1040  is less than the length (X) of arm  1060 . In some embodiments, the length (Y) of arm  1040  is greater than the length (X) of arm  1060 . 
     In some embodiments, the distance (M) between the frame  1080  rotation points  1140  of arms  1040 / 1060  are the same as the distance (N) between the support component  1030  rotation points  1140  of arms  1040 / 1060 . In some embodiments, the distance (M) between the frame  1080  rotation points  1140  of arms  1040 / 1060  is different than the distance (N) between the support component  1030  rotation points  1140  of arms  1040 / 1060 . In some embodiments, the distance (M) between the frame  1080  rotation points  1140  of arms  1040 / 1060  is greater than the distance (N) between the support component  1030  rotation points  1140  of arms  1040 / 1060 . In some embodiments, the distance (M) between the frame  1080  rotation points  1140  of arms  1040 / 1060  is less than the distance (N) between the support component  1030  rotation points  1140  of arms  1040 / 1060 . 
     In some embodiments, arms  1040 / 106  are not parallel when in the stowed position. In some embodiments, arms  1040 / 1060  are not parallel when in the intermediate position. In some embodiments, arms  1040 / 1060  are not parallel when in the deployed position. In some embodiments, arms  1040 / 1060  are not parallel through the entire range of motion of the vehicle step  1000 . 
     In some embodiments, arms  1040 / 106  are parallel when in the stowed position. In some embodiments, arms  1040 / 1060  are parallel when in the intermediate position. In some embodiments, arms  1040 / 1060  are parallel when in the deployed position. In some embodiments, arms  1040 / 1060  are parallel through the entire range of motion of the vehicle step  1000 . 
     Components of the disclosed vehicle step  1000  can comprise a structurally strong and/or light weight material. In some embodiments, the vehicle step  1000  can comprise a fiber reinforced composite material such as a carbon fiber reinforced plastic or thermoplastic with, for example, a polymer matrix or resin. In some embodiments, the vehicle step  1000  can comprise other suitable composites, plastics, thermoplastics, metals, alloys, ceramics, among others, with efficacy, as needed or desired. However, the particular material used does not limit the disclosure. 
     In some embodiments, a plurality of stepping structures can be used.  FIGS. 3A-B  illustrate an embodiment which can use a plurality of steps on a single side of a vehicle in order to, for example, retain movable running boards. As shown, a first vehicle step  1000  and a second vehicle step  1000 ′ can be used to hold a horizontal running board  8020  similar to what is described in detail above. More can be used as well, and the number of attachment mechanisms does not limit the disclosure. In some embodiments, the vehicle steps  1000 / 1000 ′ can move in concert, allowing the horizontal running board  8020  to move from the stowed position ( FIG. 3B ), through the intermediate position and into the deployed position ( FIG. 3A ). 
     Self-Energizing Mechanism for Vehicle Step 
     In some embodiments, the vehicle step  1000  can be self-energizing in either the deployed or stowed position, or in both positions. For example, a planar four-bar linkage can be used in some embodiments of the vehicle step  1000 , allowing for stability and predictability in motion of the step. In some embodiments, a planar quadrilateral linkage can be used for self-energizing the vehicle step  1000 . In some embodiments, a planar quadrilateral crank-rocker linkage can be used, which is described below. 
     In the stowed and deployed positions (respectively shown in  FIGS. 7 and 9 ), the vehicle step  1000  is in a self-energized position so that a load applied to the top of the stepping platform  1020  in a relatively downwards motion does not move the vehicle step  1000  towards an intermediate position. 
     For example, any force exerted downward onto the bar the stepping platform  1020  of vehicle step  1000  desirably will increase the resistance of the vehicle step  1000  to moving. In some embodiments, the stepping platform  1020  would need to move upward before the vehicle step  1000  can translate. 
     In some embodiments, a motor  1075  can be used in conjunction with the vehicle step  1000 . In some embodiments the motor  1075  can be rigidly mounted to the underside of a vehicle, such as through the use of a mounting bracket, thought he particular mounting method does not limit the disclosure. In some embodiments, the motor  1075  can be located generally adjacent to the vehicle step  1000 . 
     In some embodiments, the motor  1075  turns a pinion gear about an axis roughly parallel to the plane defined by the underbody of a vehicle. The pinion gear can mesh with drive teeth formed at the end of arm  1060 . Actuation of the motor  1075  can cause the pinion gear to rotate and the arm  1060  to counter-rotate with respect to the motor  1075  and pinion gear. As the arm  1060 , rotates it can push the stepping platform  1020  by virtue of its connection to support component  1030 . Thus, when the motor  1075  rotates, the motor  1075  can move the stepping platform  1020  between a stowed position ( FIG. 7 ) wherein the stepping deck is generally positioned inward from the exterior of the vehicle or fixed running board and a deployed position ( FIG. 9 ) in which the stepping platform  1020  is extended sufficiently to provide a step for at least the forefoot portion of a user&#39;s foot. 
     As the vehicle step  1000  moves between the stowed position and the deployed position under the power of the motor  1075 , arm  1040  rotates as well and the deployed position is reached when the stop contact arm  1060 . 
     When the vehicle step  1000  is in the deployed position, a downward force exerted on the stepping platform  1020  causes a stop to bear against arm  1060 . This arrangement causes the load on the stepping platform  1020  to be borne primarily by the support component  1030  and arm  1040 . In the deployed position, the vehicle step  1000  takes on a geometry such that the support component  1030  and arm  1040  are loaded in tension. The torque generated by a load on the stepping platform  1020  is opposed by arm  1060 , which is thus loaded in axial compression. Due to the particular configuration, the motor  1075  is isolated from the load on the stepping platform  1020 . 
     This aspect of the vehicle step  1000  prevents damage to the motor  1075  by eliminating “back-loading,” as there is no torque reaction about the end of arm  1060 , even when very heavy loads are placed on the stepping platform  1020 . Thus the motor  1075  is not needed to exert a counter-torque on arm  1060  to support the load on the stepping platform  1020 . This feature also eliminates the need for balky, unreliable clutches or any other means of disconnecting the motor  1075  from the vehicle step  1000 , or retractable stops or the like to engage and support the vehicle step  1000  when in the extended position. 
     With these features the vehicle step  1000  provides a practical stepping assist for a vehicle user, which can be quickly moved into an extended position for use and retracted out of the way when necessary. As detailed above, this functionality is provided with a minimum of mechanical complexity and a high level of reliability. Moreover, the vehicle step  1000  is easily connected to a vehicle&#39;s existing systems to allow even greater usability. For example, the motor  1075  may be connected to the vehicle&#39;s electrical system to cause the vehicle step  1000  to quickly move to the extended position upon shutting off the vehicle&#39;s engine, placing the vehicle in park, opening a door, or signaling the power door-lock system with a remote device or control such as a key fob control. Similarly, the motor  1075  may be signaled to retract the vehicle step  1000  upon starting the engine, placing the vehicle in drive, closing or locking the door(s) with which the step is associated, etc. 
     In the embodiment presently under discussion, when the vehicle step  1000  is in the stowed position, it is concealed, preferably completely concealed, from the view of a typical standing adult curbside observer of the vehicle. In this position the vehicle step  1000 , can be disposed behind the lowest extension or lower edge of the vehicle underbody. In some embodiments, the vehicle step  1000  is not visible to an adult standing 5 feet from the vehicle; in some embodiments, the vehicle step  1000  is not visible to an adult standing 10 feet from the vehicle; in some embodiments, the vehicle step  1000  is not visible to an adult standing 20 feet from the vehicle. 
     In some embodiments, a clutch may be used as well. 
     In some embodiments, in the self-energized position there can be some slight rotational movement of the stepping platform  1020 . For example, the stepping platform  1020  can rotate approximately 0.5, 1, 2, 3, 4, or 5 degrees without movement of the vehicle step  1000  or/or moving the vehicle step  1000  to a position where the vehicle step  1000  is not still self-energized. In some embodiments, the stepping platform  1020  can rotate approximately less than 0.5, 1, 2, 3, 4, or 5 degrees without translating the vehicle step  1000  or/or moving the vehicle step  1000  to a position where the vehicle step  1000  is not still self-energized. This ensures that the vehicle step  1000  remains self-energized even if the stepping platform  1020  is bumped and/or moves somewhat. 
     Integration of Stepping Structure and Side Bar 
     In some embodiments, the side bar  100  and step  1000  can be attached to one another through the use of a mounting bracket  150 . In some embodiments, the side bar  100  and step  1000  can be removably attached to one another. In some embodiments, the side bar  100  and step  1000  can be permanently attached to one another. Further, as discussed above, the side bar  100  may be configured to translate in comparison to the step  1000 . 
       FIG. 12  shows a reverse viewpoint with the step  1000  in the deployed position. As shown, the frame  1080  of the step  1000  can be attached to a mounting bracket  150 . The mounting bracket  150  can then be attached to the vehicle. Further, the side bar  100  can also be attached to the mounting bracket  150 , thereby forming the combination assembly  10 . As shown in  FIG. 12 , a plurality of mounting brackets  150  can be used in the combination assembly  10 . In some embodiments, the mounting brackets  150  may attach to both the step  1000  and side bar  100 . In some embodiments, the mounting brackets  150  may only attached to the side bar  100 .  FIG. 13  shows a close-up view of the connection portions of the side bar  100 , mounting bracket  150 , and step  1000 . 
       FIG. 14  shows a cross section of the side bar  100  and step  1000  in the stowed position. Specifically, as shown, at least a front edge  1010  of the stepping platform  1020  can be located within the channel  149  of the side bar main body  102 . By having the stepping platform  1020  be located within the channel  149 , the combination assembly  10  can have improved aesthetic appeal, as well as allowed the step  1000  to be located out of the way. Without such a channel  149 , the step  1000  would have to be located below or behind the side bar  100 . If it was below the side bar  100 , the step would be located in an unappealing position, and may be more easily damaged than if located within the channel  149 . If the step  100  was located behind the side bar  100 , it would have a significant distance to extend for viable use by a user, which could provide unwanted torque onto the motor  1075 . 
     In some embodiments, the step  1000  and side bar  100  can be used on both sides of vehicle  20 . In some embodiments, the step  1000  and side bar  100  are the same length (Ls/Lr) on both sides of vehicle  20 . In some embodiments, the step  1000  and side bar  100  are the different lengths (Ls/Lr) on both sides of vehicle  20 . In some embodiments, the step  1000  and side bar  100  can have a different length (Ls/Lr). In some embodiments, the step  1000  and side bar  100  can have the same length (Ls/Lr).
