Detailed Description

Examples of the present technology relate to an adjustable bench that includes an integral support. The stand allows the bench to be positioned substantially vertically in a storage or standing position. This allows the bench to occupy less floor space in a gym or other room. The bracket can be removably or permanently fastened or secured to the back support of the bench, which enables the adjustable bench to be placed in a wide range of use positions, including declined use positions, without interference from the bracket.

Figures 1A-1C illustrate various views of an adjustable bench 100. These views are depicted simultaneously, and not all components are depicted or labeled in every figure. The adjustable bench 100 includes a frame 102, a seat support 104, and a back support 106. The seat support 104 is connected to the frame 102 via a pivotable element 108 coupled to the frame 102. The pivotable element 108 may be in the form of a roller or ball bearing, a hinge, or other structure. Similarly, the back support 106 is coupled to the pivotable element 108 at a first end 109, or to a different pivotable element that is discrete from the pivotable member 108. Typically, the adjustable bench 100 is used during exercise or to facilitate exercise. Other benches may include more or fewer components (e.g., frames formed from a greater or fewer number of discrete components joined together). The frame 102 provides stability to the adjustable bench 100. The frame 102 also provides a structure to which the seat support 104 and back support 106 are connected.

Generally, the frame 102 includes a middle portion 114 that is connected to the two leg portions 110 and 112. For example, the leg portions 110 and 112 may be connected to the intermediate portion 114 via welding, bolt members, a robust, i.e., stable, chemical adhesive, or the like. In this configuration, the pivotable element 108 is fixed to the middle portion 114 of the frame 102. The frame 102 also defines a seat aperture 116. Further, an adjusting ladder 118 is fixed to the frame 102. Preferably, the seat aperture 116 is defined by a front end of the frame 102 (e.g., the leg portion 110). An adjustment ladder 118 is secured to the second leg portion 112. The seat support 104 allows independent pivotal adjustability of the seat cushion 120 relative to the frame 102. The back support 106 allows independent pivotal adjustability of the back pad 122 relative to the frame 102.

Broadly, the back cushion 122 provides a surface for supporting the torso of a user in a sitting or lying position. The back cushion 122 is a relatively large component of the adjustable bench 100 as compared to the seat cushion 120. The adjustability of the position of the two pads 120, 122 may be described as follows. The back support 106 is pivoted relative to the frame 102 about the pivot axis PA of the pivotable element 108. The positioning of the back support 106 is provided by a brace (space) 124 that is pivotably coupled to the back support. The brace 124 terminates in a pin 126, the pin 126 being selectively engageable with a gap 128 between the teeth of the adjustment ladder 118. The positioning of the brace 124 along the adjustment ladder 118 adjusts the position of the back support 106 relative to the frame 102. The adjustment ladder 118 may also include indicia that may assist the user in positioning the pins 126 in the preferred gaps 128 for the desired exercise. The back pad 122 provides a cushioning surface for the user and may be attached to the back support 106 at one or more brackets (brows) 129 using fasteners or other elements.

Broadly, the seat cushion 120 provides a surface for supporting a user in a seated or lying position. The seat support 104 pivots relative to the frame 102 about the pivot axis PA as described above. The seat support 104 is connected to the seat arc member 130 and passes through the seat aperture 116. The seat arc member 130 defines a plurality of seat arc member apertures 132. As shown, the holes 132 are not equally spaced from one another. However, in some cases, the apertures 132 are equally spaced along the seat arc member 130, or the arc member may have a different curvature than depicted. The seat cushion 120 provides a cushioning surface for the user and may be attached to the seat support 104 at one or more brackets using fasteners or other elements. The seat adjustment pin 134 may be positioned on the frame 102 such that the seat adjustment pin 34 may be selectively coupled to the seat arc member 130 through the seat aperture 116. The seat adjustment pin 134, in combination with the plurality of seat arc member apertures 132 defined by the seat arc member 130, enables selective pivoting and positioning of the seat support 104. In an example, the seat support 104 may include structure that allows sliding movement of the seat cushion 120 relative to the hinge 108, for example, as described in many examples of U.S. patent No. 10,589,144, the disclosure of which is incorporated herein by reference in its entirety.

The back support 106 is pivotally adjustable within a range of motion relative to the frame 102. The pivotal movement of the back support 106 is independent of the pivotal movement of the seat support 104. The degree of pivoting of the back support 106 is shown as an angle θ relative to the horizontal H. The pivoting above H is positive θ, while the pivoting below H is negative θ. In an example, the pivot range of the back support is at least 0 ° (i.e., horizontal) and no greater than about 90 ° (vertical). In some examples, the range of pivotal movement of the back support 106 is no greater than about 80 °. The back support 106 can be positioned at from about 0 ° to 90 ° with respect to horizontal. In another example, the back support 106 can be positioned at from about 0 ° to 85 °. In another example, the pin 124 may be positioned in a gap 128a, the gap 128a positioning the back support 104 in a so-called declined use position, which may be desirable for certain exercises. This may be a declination angle of up to about 5 °, up to about 8 °, or up to about 10 °.

The degree of pivoting of the seat support 104 is shown as an angle alpha relative to the horizontal H. Pivoting above H is a positive value of a and pivoting below H is a negative value of a. In an example, the range of pivotal movement of the seat support 104 is at least 0 ° (i.e., horizontal) and no greater than about 90 ° (vertical). In some examples, the range of pivotal movement of the seat support 104 is no greater than about 75 °. The seat support 104 may be pivotable from 0 deg. to about-25 deg. or more relative to the horizontal H.

Front legs 136 are provided at the ends of the leg portions 110, proximal to the seat cushion 120. In the depicted example, the feet 136 have a width sufficient to resist rocking when the bench 100 is used for exercise. The feet 136 may also include an integral handle 138 that may be used to lift the end of the bench 100 proximal to the seat cushion 120. The frame 102 also includes lateral supports 140 distal of the feet 136 at the ends of the frame 102 proximal of the back pad 122. The lateral support 140 provides stability to the bench 100 when in use. A rear leg 142 is provided at each end of the transverse structure 140. Two housings 144 also extend from the lateral support 140. Each housing 144 houses one or more rollers 146 to enable easy rolling movement of the bench 100, as described in more detail below. Each housing 144 also includes an upstanding surface, i.e., facade 148, described in more detail below. Finally, the bench 100 includes a bracket 150, the bracket 150 being coupled to the second end 149 of the back support 106, and described in more detail below. The surface of the bracket 150 is disposed a distance D2 from the hinge 108 that is greater than the distance D1 of the distal portion 152 of the back pad 122 from the hinge 108. This enables the stand 150 to protect the back pad 122 when in a standing or storage position, as described below.

Fig. 2 depicts a partially exploded perspective view of an end of the adjustable bench 200. In relevant part, fig. 2 shows a bracket 202 removably coupled or mounted to the adjustable bench 200. The brackets 202 may be fixedly secured to the back support 204 of the bench 200 directly or via brackets 206 secured thereto, wherein the brackets 206 provide further support for a back pad 208. In the depicted configuration, the bracket 202 is removably coupled or mounted to the bracket 206 via a pair of screws 210, which in examples may be rotatable via a tool such as a hex wrench, screwdriver, or ratchet; or in other examples may be manually rotatable, such as thumb screws, i.e., thumb screws, or knob screws. The stand 202 includes a base 212, the base 212 including a rest surface 214 on one side thereof. The base 212 is disposed substantially orthogonal to a pair of prongs 216, each defining an opening for receiving one of the screws 210. Each fork 216 includes an offset 218, which offset 218 is adapted to the thickness of the bracket 206 so that the components of the bracket 202 remain tightly disposed to the backing pad 208. This helps to minimize interference between the user and the support 202 when the bench 200 is used for certain exercises. Similarly, the base 212 is disposed in closer proximity to the distal end 220 of the back pad 208 so as to at least partially enclose the distal end 220. As described herein, the width W of the stand base 212 may be such as to completely or almost completely cover the end portion 220 of the back pad 208 when the bench is placed in certain positions, so as to protect the back pad 208 from wear. The brace 202 is made of a robust, i.e., stable, material (such as steel) that is significantly more rigid than the material forming the back pad 208, thus forming a component that can support the weight of the bench 200 in certain positions.

Different configurations of the stent 202 are contemplated. In the depicted configuration, prongs 216 are provided on either side of the back support 204. In other examples, the prongs may be disposed at an angle of substantially 90 ° to the depicted angle, and may be fixed to either side of the back support 204 itself, opposite the brackets 206, as depicted. In other examples, the bracket 202 may be configured to have an end that may be inserted into and secured to the end 222 of the back support 204. This may be particularly advantageous because the back support 204 may be formed of hollow tube steel having a square profile; a similarly shaped mating configuration extending from the base 212 may be readily envisioned by one skilled in the art.

Fig. 3A, 3B and 3C depict the adjustable bench 300 in a use position, a mobile position and a storage position, respectively. These positions are described with respect to a surface S (e.g., the floor of a gymnasium). In the use position depicted in fig. 3A, the bench 300 may be positioned such as depicted, wherein the bench 300 is supported in a substantially horizontal position (e.g., as defined by the upper surface of the seat cushion 302 or back cushion 304 being substantially parallel to the surface S). In the use position, the bench 300 is supported on the front leg 306 and the rear leg 308. In one example, these legs 306, 308 may correspond to legs 136, 142, such as depicted in fig. 1A-1C. In the context of an adjustable bench, such as the type depicted and described herein, a plurality of use positions are contemplated. For example, any location where the adjustable bench 300 is usable for exercise may be considered a use location. In the use position, the seat cushion 302 and/or the back cushion 304 may be raised, lowered, or remain substantially horizontal. In each use position, unless the bracket 316 is removed by the user, the bracket 316 remains coupled to the back support that supports the back pad 304. As such, the user may place the adjustable bench 300 in a declined use position without interference from the stand 316, such as depicted and described in more detail in fig. 4.

In the mobile position depicted in fig. 3B, the bench 300 may be positioned such as depicted, wherein the seat end of the bench 300 has been lifted from the surface S, such as by a user grasping and lifting the handle 310. With the end lifted, the front leg 306 is raised relative to the surface S such that the bench 300 is supported on rollers 312 and can be easily moved around a space. In one example, these rollers 312 may correspond to rollers 146, such as depicted in fig. 1A-1C.

In the storage or standing position depicted in fig. 3C, the bench 300 may be positioned such as depicted, wherein the bench 300 is supported in a substantially vertical position (e.g., as defined by the upper surface of the seat cushion 302 or back pad 304 that is substantially orthogonal to the surface S). In the storage position, the bench 300 is supported on the surface and riser 314 of the stand 316. In one example, facade 314 and stand 316 may correspond to facade 148 and stand 150 (more specifically, a resting surface thereof), such as depicted in fig. 1A-1C. In the storage position, the adjustable bench 300 stands upright, which reduces the footprint of the adjustable bench 300 during periods of non-use.

Fig. 4 depicts the adjustable bench 400 in a declined use position. Some of the components in fig. 4 are described elsewhere herein, but are not necessarily further described or labeled. The components of the bench 400 that are not described in detail will be apparent to those skilled in the art upon reading this disclosure. In this position, the pin 402 is disposed in the declination gap 404 of the adjusting ladder 406. The pin 402 is connected to an end portion of a brace 408 that is pivotably coupled to a back support 410. In this position, the back pad 412 is in a declined use position. In connection with the present technique, the support 414 is maintained in a fixed position relative to the back pad 412. In this manner, by securing the support 414 relative to the back support 410 and the back pad 412, greater versatility, i.e., versatility, of the bench 400 (and other similar benches described herein) is increased. Known adjustable benches (such as depicted in fig. 3C) that may be positioned in a standing position utilize brackets secured to posts or other protrusions extending upward from a portion of the bench (such as from a frame or lateral support, as depicted in fig. 1A-1C). This post or support prevents the known bench from being placed in a declined use position, as the post is typically used to further support the distal end of the back support, which is disposed distally of the hinge. As such, the techniques described herein show significant improvements over existing approaches.

While the brackets described herein secured to the back support improve versatility, i.e., versatility, of benches that may be placed in a reclined use position, brackets secured to the back support may still improve adjustable benches that do not include such a recline function. Fig. 5 and 6 depict other examples of non-downtilt adjustable benches 500, 600 having integral brackets 514, 614. Fig. 5 depicts an adjustable bench 500 adjusted by selectively engaging a pin 502 with one or more openings 504 on an arc-shaped member 506. A similar pin and arc member adjustment system 522 is used to move the seat 524. However, even with such adjustability, the adjustable bench 500 includes a frame or base 520 that prevents the back support 510 from being lowered to a position below horizontal. The base 520 provides support to the distal end of the back pad 512 during use. The adjustable bench 500 also includes a plurality of handles and wheels to increase the maneuverability of the bench 500 within a potentially limited area of an exercise room or gym. For example, the user may grasp the front handle 526 so that the front end of the bench 500 may be lifted, thereby engaging one or more rear wheels 528 with the floor, thereby allowing the user to roll the bench 500 around the room. Alternatively or additionally, the bench 500 may include a rear handle 530, which may be grasped by the user so that the rear end of the bench 500 may be lifted, thus engaging one or more front wheels 532 with the floor, allowing the user to roll the bench 500 around the room. Additional accessories are also depicted in fig. 5. For example, the rear corner portion of the frame or base 520 is reinforced by braces 534. One or more strap pegs 536 may extend from either or both sides of the brace 534 to enable an elastic strap to engage the bench 500, thereby providing another resistance exercise device available to a user of the bench 500.

Fig. 6 depicts an adjustable bench 600 that is adjusted by selectively engaging pins 602 with one or more gaps 604 on an adjustment ladder 506. A similar ladder adjustment system 622 is used to move the seat 624. Even with such adjustability, however, the adjustable bench 600 includes a post 620, the post 620 preventing the back support 610 from being lowered to a position below the horizontal. The post 620 provides support to the distal end of the backing pad 612 during use. In both configurations of the adjustable benches 500,600, securing the brackets 514, 614 to the back supports 510, 610 helps to protect the end portions of the back liners 512, 612 from wear or puncture due to inadvertent contact with walls or equipment within the tight confines of a gym or other room. The post 620 depicted in fig. 6 may have a fixed or adjustable height. Fig. 7A-7C depict benches having height-adjustable columns.

Fig. 7A-7C depict enlarged partial views of an adjustable bench 700 having an adjustable support column 702. Fig. 7A to 7C are also described. As with the other adjustable benches depicted herein, the adjustable bench 700 includes a back support 704 pivotally coupled to a frame 706. The back support 704 has a back cushion 708 secured thereto, and a bracket 710, such as depicted elsewhere herein. The position of the back pad 708 may be adjusted by adjusting the position of the brace 712 relative to the adjustment ladder 714. As described elsewhere herein, the brace 712 can be pivotally coupled to the back support 704. While an adjustment mechanism is depicted that includes a brace 712 and an adjustment ladder 714, other adjustment mechanisms (such as depicted in fig. 4 and 5) that utilize pins that can be selectively positioned in openings of the arcuate members are also contemplated for the depicted adjustable bench 700. The adjustable bench 700 also includes a foot 716. The proximal end 718 of the adjustable support column 702 is secured to either or both of the foot 716 and the frame 706. The distal end 720 is telescopically slidable into and out of the proximal end 718, and its position can be adjusted by selectively engaging a pin 722 therewith (e.g., with an opening 724 in the distal end 720). In the depicted configuration, the proximal end 718 is an outer housing in which the distal end 720 in the form of a post is slidably disposed.

In fig. 7A, the adjustable bench 700 is depicted in a horizontal use position, wherein the back pad 708 is disposed substantially flush with the floor on which the adjustable bench 700 rests. In this horizontal use position, the adjustable support 702 is in contact with the back support 704 to provide support thereto. In this position, the adjustable support 702 may be at its maximum height, greater than the height depicted in fig. 7B. Once the distal end 720 of the adjustable support 702 is lowered, the brace 712 can be adjusted relative to the adjustable bench 700 and the adjustment ladder 714 positioned in a declined use position, with the distal end 720 contacting the back support 704 to provide support thereto. Depending on the number of openings 724 in the distal end 720, a plurality of declined use positions may be envisaged. In fig. 7C, the adjustable bench 700 is depicted in an inclined use position, wherein the brace 712 is positioned on the adjustment ladder 714 to include the back support 704 and the back cushion 708. In the tilted use position, the distal end 720 is at its maximum height, but separated from the back support. In all three positions depicted in fig. 7A-7C, the bracket 710 remains adjacent the back pad 708, minimizing damage thereto from collisions with walls or other surfaces and equipment.

Fig. 8A-8B depict perspective and exploded perspective views, respectively, of a sliding seat adjustment mechanism 800 for an adjustable bench. The benches as depicted in fig. 1A-1C, 3A-3C, and 5 may employ such a sliding seat adjustment mechanism 800. The sliding seat adjustment mechanism 800 is capable of changing (e.g., increasing or decreasing or eliminating) the size of a gap that may exist between the seat cushion and the back cushion of the adjustable bench, depending on the various relative positions of the seat cushion and the back cushion to each other. Such a gap, and the adjustment of the gap, is depicted in fig. 9A-9C. Fig. 8A and 8B are depicted simultaneously, and not all of the depicted components are visible in both figures. The sliding seat adjustment mechanism 800 is supported by a seat support 802 of the adjustable bench, which seat support 802 may be pivotally connected to a frame of the adjustable bench (such as the frame 102 in fig. 1A and 1B) at a pivotable element (such as the pivotable element 108 in fig. 1A and 1B). The seat support is also depicted in fig. 1B as seat support 104. Generally, the seat support provides a base structural support for a seat cushion, such as seat cushion 830 in fig. 8A and 8B. In the case of the sliding seat adjustment mechanism 800 of fig. 8A and 8B, the seat support 802 provides the basic structural support for the various components described herein, both supporting the seat cushion 820 and enabling the functionality of adjustability described herein. The mechanism 800 includes an adjustment frame 804 coupled to the seat support 802. In the depicted embodiment, the adjustment frame 804 includes: a side or central portion 806 defining a plurality of openings 808, a front portion 810 facing the front of the bench, and a rear portion 812 facing the rear of the bench. Adjusting the segment frame 804 provides a robust coupling, i.e., a secure connection, to the track 824 with the seat support, and the seat cushion 820 can slide on the track 824.

The central portion 806 of the adjustment frame 804 defines a substantially vertical member defining an opening 808 configured to selectively receive an adjustment pin 814. The adjustment pin 814 is coupled to a planar seat plate 818 via a pin flange 816. The seat pan 818 supports the seat cushion 820, and a user may be supported fully or partially on the seat cushion 820 during use of the bench. The seat plate 818 is coupled to a pair of bearings 822, but in some examples a single bearing may be employed. Each bearing 822 is slidingly engaged with one of two rails 824 that are connected at a first end to the front portion 810 of the adjustment frame 804 and at a second end to a rail flange 826, which rail flange 826 is in turn connected to the seat support 802. At least one of the track flanges 826 is disposed within the volume defined by the adjustment frame 804.

The depicted configuration supports the weight of the user, as well as any weight they may hold, from the seat cushion 820 to the planar support plate 818, to the pair of bearings 822, to the pair of rails 824, which are ultimately supported at either end by rail flanges 826 and the front portion 810 of the adjustment frame 804. This distributes the weight to points of contact with the seat support 802. Furthermore, neither the weight of the user nor the weight held by the user is transferred to the central portion 806 of the adjustment frame 804 via the adjustment pin 814. This prevents potential distortion of the adjustment frame 804 under load (if any is transferred by the adjustment pins 814) and, more importantly, enables the user to adjust the position of the seat cushion 820 while being fully supported. Since the adjustment pin 814 is also provided at one side (opposite to the lower face) of the seat adjusting mechanism 800, a user can easily grasp the adjustment pin 814 while sitting, so that the position of the seat cushion 820 can be quickly changed. In another example, the second end of the track 824 may be connected to the rear portion 812 of the adjustment frame 804 instead of the track flange 826, which may enable a longer range of motion of the sliding seat adjustment mechanism 800. A greater number of openings 808 and/or a wider distribution thereof may also increase the range of motion. Some known adjustable benches include an adjustment pin that engages a pivot member (e.g., such as the seat support 802) that supports the seat cushion. By utilizing the sliding seat adjustment mechanism 800 depicted herein (with the adjustment pins 814 engaged with the adjustment frame 804), the user does not need to reach under and around the track 824, thus reducing or eliminating the possibility of pinching a finger during adjustment. Furthermore, by employing a separate adjustment frame 804, no openings need be formed in the seat support 802 to engage the adjustment pins, thereby limiting the likelihood of deformation of the seat support 802. Other advantages of this configuration over the prior art will be apparent to those skilled in the art.

As described above, the relative positions of the various components of the sliding seat adjustment mechanism 800 enable the components to be conveniently used by a user. The mechanism 800 may be adjusted when a user sits on the seat cushion 820 or elsewhere. The seat cushion 820 is supported on a first or upper planar 828 surface of the seat pan 818. The side surface or central portion 806 also defines a second or side plane 829 surface, which in the depicted example is substantially orthogonal to the upper plane 828. The orthogonal orientation of these two components enables the adjustment pin 814 to be disposed on one side of the adjustment frame 804 such that a user can easily grasp and manipulate (e.g., pull) the adjustment pin, whether sitting or otherwise. Furthermore, the adjustment pin 814 is more easily visible to the user (whether sitting or not) than an adjustment pin provided under the seat that needs to be pulled down to adjust the seat position. By placing the adjustment pin 814 at the side of the mechanism 800, the adjustment pin 814 is also easier to grasp, especially for users with shorter arms or arms with a limited range of motion. In the position depicted in fig. 8A and 8B, which requires a sideways horizontal pulling, the axis Ap of the adjustment pin 814 is disposed substantially orthogonal to the second plane 829 of the adjustment frame 804 and substantially parallel to (and below) the first plane 828 of the planar seat plate 818.

In addition to being readily accessible to the adjustment pin 814, positioning the sliding seat adjustment mechanism 800 as depicted in fig. 8A and 8B facilitates balancing the load on either side of the seat support 802 through the use of a pair of rail/bearing systems, each rail/bearing system being disposed on either side of the seat support 802. Each of the track 824, seat support 802, and central portion 806 of the adjustment frame 804 is defined by respective axes that are substantially parallel to each other and to an axis defined by the length of the associated bench. Such an axis would be parallel to the horizontal H-line depicted and described in fig. 1C. The adjustment pins 814 are defined by adjustment pin axes that are substantially orthogonal to all of these axes, and the adjustment pins 814 may be inclined to some of the axes depending on the position of the adjustment pins 814 relative to the axis of each track 824, for example. Furthermore, by positioning the adjustment pin 814 in an outer position of the adjustment frame 804 relative to at least one track 824, accidental access to the track 824 and associated bearings 822 is limited because those components are disposed within the adjustment frame 804. Additional plates positioned opposite the support structure 802 from the central portion 806 may be secured to the adjustment frame 804 if needed or desired to prevent access near the rails 824 and bearings 822. Additionally, a plated or strong metal or plastic mesh may be installed on the underside of the mechanism 800, such as under the seat support 802, to prevent inadvertent contact with or damage to components of the mechanism 800.

For example, if the sliding seat adjustment mechanism 800 is sold as a kit, including all of the components depicted in fig. 8A and 8B (except for, for example, the seat support 802), the sliding seat adjustment mechanism 800 may include a seat support 802 or may be secured to the seat support 802. Such sliding seat adjustment mechanisms may be secured to the existing seat support of the pivot bench (once the existing seat cushion is removed) using appropriate bolts, screws, or other fasteners provided within the kit. Thus, existing adjustable benches that do not have a sliding seat function may be retrofitted, for example, by an end user to increase their versatility, i.e., versatility. Because the sliding seat adjustment mechanism described herein is not engaged with the seat support of the adjustable bench except for support, the structures described herein may be used in many different types of adjustable benches.

Fig. 9A-9C depict partial side views of the sliding seat adjustment mechanism 800 of fig. 8A-8B for use with the adjustable bench 900. Examples of such adjustable benches are described, for example, in fig. 1A-1C, 3A-3C, and 5. For illustrative purposes, the depicted structure includes a frame 902, a pivot 904, and a pivot mechanism including a seat arc member 906. An adjustable bench utilizing other pivoting mechanisms may similarly incorporate a modified sliding seat adjustment mechanism 800 such as described herein, or as will be apparent to those of skill in the art, to accommodate different configurations of pivoting mechanisms. Certain components described above in the context of fig. 8A and 8B are depicted, but need not be further described in the following figures.

As described in the context of fig. 8A and 8B, the sliding seat adjustment mechanism 800 is supported by the seat support 802 and includes an adjustment frame 804, the adjustment frame 804 defining a plurality of openings 808 in a central portion 806 thereof. The adjustment pins 814 may be selectively engaged with the plurality of openings 808 as desired to adjust the position of the seat cushion 820 relative to the back cushion 908. One of the tracks 824 is depicted in phantom, as is a bearing 822 that is slidable along that track 824. The bearing 822 is coupled to the planar seat plate 818 as is the pin flange 816. The seat cushion 820 is secured to the planar seat pan 818 on the side opposite the rails 824. The axis a of the track is depicted as axis a and, in one example, is considered to be parallel to an axis of the adjustable bench 900 defined by the seat support 802. In fig. 9A, the seat cushion 820 is depicted in a position closest to the back pad 908, wherein the gap therebetween (depicted as 910 in fig. 9B and 9C) has been reduced or eliminated. In this position, the adjustment pin 814 engages the opening 818 nearest the pivot 904, bringing the seat cushion 820 into its closest position to the back pad 908. The sliding adjustment of the sliding seat adjustment mechanism is depicted in fig. 9B and 9C. In these figures, as the pin 814 further engages the opening 818 along the adjustment frame 804 (and further from the pivot 904 at which the seat support 802 is connected to the frame 902), the gap 910 between the seat cushion 820 and the back pad 908 increases in size.
