## Background
TECHNICAL FIELD
This disclosure relates to a backrest to allow one or more people to comfortably sit in or near an automobile storage area, and in particular, to a removable backrest that is easily installed and removed from an automobile storage area.
BACKGROUND OF THE DISCLOSURE
Pickup trucks and other types of vehicles, such as hatchback cars and station wagons, include an area toward a rear of the vehicle that provides cargo space. In the case of a pickup truck, this space is called a “truck bed,” while in other types of vehicles this space is often called a “trunk.” In some cases, these automobiles also include a horizontally-opening door positioned at a rear end of the vehicle to provide access to the cargo space. In some cases, the door is hingedly attached to the automobile at a lower end of the storage space so that the door opens to a horizontal, substantially flat position. In many cases, this type of door is called a “tail gate.”
Because tail gates and other horizontally-opening doors are positioned in a horizontal orientation when opened, users often utilize the door as a place to sit. However, prolonged sitting on a tailgate can be very uncomfortable as the horizontal door is not designed as a seat and thus does not include a backrest. It would be beneficial to have a removable backrest for use near a horizontally-opening door of an automobile storage space to allow for more comfortable use of the door as a seat.

In some embodiments, the backrest member 118 is removably installed in or near the storage space 102 of the automobile 104 by removably coupling a first extension member 108 and a second extension member 110 to opposite sides 112 and 114 of the automobile storage space 102. As such, the backrest member 118 is suspended above a floor 116 of the automobile 104 storage space 102 adjacent to the rear door 106 to provide a back support for users who are seated on the rear door 106. In some embodiments, the width of the backrest system 100 is adjustable to account for the different widths of the storage space 102 of various automobiles 104. In some embodiments, the backrest system 100 is constructed of a material that is weather resistant and can remain coupled to an exposed storage space 102 of an automobile 104, such as a truck bed of a pickup truck, while the rear door 106 is in the open or closed position. A single user can easily install or remove the backrest system 100 and can compact the system 100 for easy storage in the automobile storage space 102 or elsewhere in the automobile 104.
Referring again to FIG. 1A, in some embodiments the backrest system 100 includes a backrest member 118 that includes a front surface 120 and a back surface 122; a channel 124 (see also FIG. 3) coupled to the back surface 122 of the backrest member 118; a first extension member 108 movably positioned in the channel 124; a second extension member 110 movably positioned in the channel 124; a first coupling member 126 positioned on a first side 112 of the automobile 104 storage space 102; and a second coupling member 128 positioned on a second side 114 of the automobile 104 storage space 102. In some embodiments, the front surface 120 of the backrest member 118 includes one or more surface features 132 to increase the durability and/or comfort of the backrest member 118. As shown in FIG. 1A, the backrest member 118 is securable in an elevated position above the floor 116 of the storage space 102 by removably coupling the first extension member 108 to the first coupling member 126 and removably coupling the second extension member 110 to the second coupling member 128. The position of the first and second extension members 108 and 110 with respect to the backrest member 118 is adjustable to adjust the total width of the backrest system 100. In some embodiments, the first and second extensions members 108 and 110 are movable along a longitudinal axis 130 of the backrest member 118 to extend (or retract) the total width of the backrest system 100. Thus, in some embodiments the backrest system 100 can be sized to fit within various storage spaces 102.
In some embodiments, the backrest member 118, the first extension member 108 and the second extension member 110 are made of weather resistant material, such as, for example, a metal material or a hardened plastic material. In addition, in some embodiments the coupling members 126 and 128 are also made of a weather-resistant material. In some embodiments, the backrest system 100 remains attached to an exposed storage space 102, such as a truck bed of a pickup truck, when the system 100 is not in use. In addition, as shown in FIG. 1B, in some embodiments the backrest system 100 is positionable in the automobile storage space 102 such that the rear door 106 of the automobile 104 can be positioned in the closed position while the system 100 is installed.
Referring again to FIG. 1, in some embodiments the coupling members 126 and 128 are removably coupled to the side surfaces 112 and 114 of the storage area 102 of the automobile 104 while in other embodiments the coupling members 126 and 128 are permanently coupled to the side surfaces 112 and 114 of the storage area 102. In yet other embodiments, the coupling members 126 and 128 are integrally formed with the side surfaces 112 and 114 of the storage space 102.
Referring now to FIG. 2, in some embodiments the backrest member 118 includes a body section 134, a first flange 136 extending from a top end 140 of the body section 134, and a second flange 138 extending from a bottom end 142 of the body section 134. The first and second flanges 136 and 138 extend along a longitudinal axis 130 of the backrest member 118 and provide structural strength to the backrest member 118. In the embodiment of FIG. 2, the body section 134, the first flange 136 and the second flange 138 are rectangular and planar. However, in other embodiments the body section 134, the first flange 136 and the second flange 138 have other shapes and surface structures. For example, in other embodiments the body section 134 has a curved shape and the first and second flanges 138 extend along the curved edges of the body section 134. In other embodiments, the body section 134 has indentations and contours to conform to the shape of a user's back. In other embodiments, the backrest member 118 does not include flanges 136 and 138 and is made of a thick material to provide structural strength to the backrest member 118.
Referring now to FIGS. 3A and 3B, in some embodiments the channel 124 is coupled to the back surface 122 of the body section 134 and includes a C-shaped cross section. In some embodiments, an open side 144 (see FIG. 3B) of the C-shaped channel 124 is coupled to the back surface 122 of the backrest member 118 so that the channel 124 and the back surface 122 of the backrest member 118 form a rectangular opening. In other embodiments, the channel 124 has another cross-sectional shape. In some embodiments, the channel 124 has a length that is slightly shorter than the length of the backrest member 118. As illustrated in FIG. 3A, in some embodiments the channel 124 is positioned between the first flange 136 and the second flange 138 on the backrest member 118. The channel 124 has a first open end 146 and a second open end 148 through which the first and second extension members 108 and 110, respectively, are movable. As shown in FIG. 2, the first and second extension members 108 and 110 are movable within the first and second open ends 146 and 148 to adjust the width of the backrest system 100.
Referring now to FIG. 3C, in some embodiments the extension members 108 and 110 (extension member 108 is shown in FIG. 3C) also have a C-shaped cross-sectional shape and are positioned within the channel 124 such that an open side 150 of the extension members 108 and 110 faces away from the body section 134. As shown in FIG. 3C, in some embodiments the extension members 108 and 110 are slightly smaller than the channel 124 so that the extension members 108 and 110 are movable within the channel 124.
Referring now to FIGS. 4A and 4B, in some embodiments the first and second extension members 108 and 110 are inextensible and rigid. In other embodiments, the first and second extension members 108 and 110 are extensible, for example, by way of a telescoping extension feature. In some embodiments, the first and second extension members 108 and 110 each include a protrusion 152 and 154, respectively, positioned on an exposed end 156 of the extension members 108 and 110. In some embodiments, the first and second extension members 108 and 110 also include a cutout portion 158 adjacent to the first and second protrusions 152 and 154. In some embodiments, the protrusions 152 and 154 extend in the same direction as flanges 172 of the extension members 108 and 110. The protrusions 152 and 154 are configured to removably secure the first and second extension members 108 and 110 to coupling members 126 and 128 on the sides 112 and 114 of the automobile 104 storage space 102.
Referring now to FIGS. 5A and 5B, in some embodiments the first and second coupling members 126 and 128 each include a coupling portion 160, a shoulder 162, and a body section 164. In some embodiments, the coupling portion 160 is configured to be secured to a side 112 or 114 of the storage space 102 of an automobile 104, such as a side wall of the truck bed. The shoulder 162 extends between the coupling portion 160 and the body section 164, and positions the body section 164 in a spaced apart relationship to the surface of a side 112 or 114 of the automobile storage space 102 when the coupling member 126 or 128 is secured in a storage space 102. The body section 164 extends from the shoulder 162 and includes a slot 166 that is configured to receive a portion of one of the extension member 108 and 110. In some embodiments, for example, a linking portion 168 of the extension member 108 or 110 adjacent to the cutout portion 158 is positionable within the slot 166 to removably secure the extension member 108 and 110 to the coupling member 126 or 128 so that the protrusion 152 or 154 is positioned between the body section 164 of the coupling member 126 or 128 and the surface of a side 112 or 114 of the automobile storage space 102 and the linking portion 168 is located within the slot 166. In other words, a user can secure the extension members 108 and 110 to the coupling members 126 and 128 by sliding the linking portions 168 within the slots 166. In some embodiments, the slots 166 are oriented at a non-vertical angle 170 so that the backrest member 118 is also at a non-vertical angle when the first and second extensions 108 and 110 are secured to the first and second coupling members 126 and 128, respectively. To remove the backrest member 118, a user slides the first and second extension members 108 and 110 upwards until the linking portions 168 are removed from the slots 166.
Referring again to FIGS. 1A-5B, to use the system 100 a user moves the first and second extension members 108 and 110 along the horizontal axis 130 to position the first and second extension members 108 and 110 so that the overall width of the backrest system 100 matches the width of the storage space 102 and so that the exposed ends 156 of the first and second extension member 108 and 110 are aligned with the coupling members 126 and 128. The user then slides the linking portion 168 of each extension member 108 and 110 into the corresponding slot 166 of the first and second coupling member 126 and 128 to secure the backrest member 118 to the storage area 102. In order to remove the backrest member 118, the user lifts the backrest member 118 away from the coupling members 126 and 128 so that the linking portions 168 of the extension members 108 and 110 slide out of the slots 166. The user can then retract the extension members 108 and 110 toward the backrest member 118 for compact storage of the backrest system 100.
The foregoing describes only some embodiments of the invention(s), and alterations, modifications, additions and/or changes can be made thereto without departing from the scope and spirit of the disclosed embodiments, the embodiments being illustrative and not restrictive. For example, in other embodiments, other types of coupling mechanisms are used to removably couple the backrest member 118 to the automobile storage space 102. For example, in some embodiments the first and second extension members 108 and 110 are removably coupled to features that are integral with the automobile storage space 102 (e.g., slots or other feature that are built into the side walls 112 and 114 of the automobile storage space 102). In other embodiments, the first and second extension members 108 and 110 are removably coupled to the first and second coupling members 126 and 128 (which may be coupled to the automobile storage space 102 or integral with the storage space 102) by a method other than the interaction between the linking portions 168 and the slots 166. For example, in some embodiments the first and second coupling members 126 and 128 include a rectangular opening in the body section 164 and the first and second extension members 108 and 110 are extended within the openings to removably secure the first and second extension members 108 and 110 to the automobile storage space 102.
In other embodiments, a cushion (not shown) is movably coupled to the backrest member 118 to provide additional comfort to a user. For example, in some embodiments the backrest member 118 includes a plurality of openings (not shown) along the top end 140 of the body section 134 and a cushion with a corresponding number of hooks is secured to the backrest member 118 by coupling the hooks to the openings. Thus, in some embodiments a user can selectively position the cushion between the user's back and the backrest member 118, for example, by flipping the cushion from the back side of the backrest member 118 to the front side of the backrest member 118. In other embodiments, a user can secure the first and second extension members 108 and 110 to the backrest member 118 to hold the first and second extension members 108 and 110 in position with respect to the backrest member 118. For example, in some embodiments, one or more set screws (not shown) are positioned in the channel 124 such that the set screws can be tightened to secure the first and second extension members 108 and 110 in position with respect to the channel 124. Thus, in some embodiments the user can adjust the backrest system 100 to the width of the storage space 102 of the user's automobile 104 and then secure the first and second extension members 108 and 110 in place at the desired width using the set screws.
