Referring to FIGS. 1-8, reference numeral 20 generally indicates a vehicle. A cabin 24 of the vehicle 20 includes a vehicle seating assembly 28. The vehicle seating assembly 28 includes a seat 32 that is pivotable between an open position (FIG. 2) and a closed position (FIG. 1). A cavity 36 is formed in a support structure 40 of the seat 32 such that an occupant is supported on a support rib 44. The cavity 36 may be utilized as a storage bin. The cavity 36 is equipped with one or more compartments 48. The one or more compartments 48 may be a single compartment, may be multiple compartments that are separated from one another, may be multiple compartments that are partially bisected by dividers (e.g., the support ribs 44), and/or combinations thereof.
Referring again to FIG. 1, the cabin 24 of the vehicle 20 typically includes a front row 52 of seat assemblies and a rear row 56 of seat assemblies. The vehicle seating assembly 28 includes the seat 32, which is generally horizontal and configured to receive a seated occupant thereon, and a seatback 60, which may extend upright at an angle. The seatback 60 may be pivotally coupled to the seat 32. In some embodiments, the rear row 56 of seat assemblies may fold flat such that the seatback 60 pivots forward and rests on top of and directly abuts the seat 32. The seatback 60 of the rear row 56 of seat assemblies often is provided with a 60/40 split such that two of three seating positions in the rear row 56 of seat assemblies are provided with their seatbacks 60 integrally formed together while the third of three seating positions is independently operable. Accordingly, a user may selectively stow the seatback 60 in a forward dumped position while maintaining a portion of the seating capacity of the rear row 56 of seat assemblies.
Referring to FIG. 2, the seat 32 is shown rotated upward to an open position such that the cavity 36 in the support structure 40 is exposed. The seat 32 may rotate about an axis that is transverse to the direction of travel of the vehicle 20. The rotational axis that the seat 32 rotates about may be defined by a seat frame bar 64 (FIG. 3). An underside of the seat 32 may include anti-submarine bowls 68 that aid in preventing an occupant from submarining in the vehicle seating assembly 28 during a vehicle impact event (e.g., a vehicle collision). The anti-submarine bowls 68 may be molded into the seat 32 in an integral fashion. For example, the anti-submarine bowl 68 may define a lower surface or support liner of the seat 32. The underside of the seat 32 may further include one or more retention ridges 72 and one or more positioning structures 76. The retention ridges 72 and/or the positioning structures 76 may prevent unintentional movement of the seat 32 relative to the support structure 40 in lateral and/or longitudinal directions (i.e., side-to-side and front-to-back motion). The retention ridges 72 may generally correspond to at least a portion of the cavity 36 in the support structure 40. For example, the retention ridges 72 may rest within at least a portion of the cavity 36 such that the retention ridges 72 correspond with or engage with a wall of the cavity 36 and extend from the underside of the seat 32 downward into the cavity 36.
Referring again to FIG. 2, the positioning structures 76 may correspond with positioning recesses 80 in the support structure 40. The positioning structures 76 may protrude from the underside of the seat 32 in a generally tapered or step-like fashion from a larger cross section at the underside of the seat 32 to a smaller cross section at a lower extreme of the positioning structures 76. The tapered and/or step-like configuration of the positioning structures 76 may aid in proper positioning and coupling of the positioning structures 76 with the positioning recesses 80. The positioning recesses 80 may have a generally complimentary configuration designed to receive the configuration of the positioning structures 76 such that the positioning structures 76 and the positioning recesses 80 are generally in continuous contact with one another when the seat 32 is in the closed position. The positioning recesses 80 may be positioned on a support ridge 84 of the support structure 40. The support ridge 84 of the support structure 40 may have a greater thickness at the sides of the support structure 40 than at a front of the support structure 40. The cavity 36 in the support structure 40 may include a forward shelf 88 that may receive the retention ridge 72 of the seat 32. The support structure 40 may be made from foam or foam-like material (e.g., expanded polypropylene, expanded polystyrene, and the like).
Referring further to FIG. 2, a forward compartment 92 of the cavity 36 may be located proximate a front wall 96 of the support structure 40. The forward compartment 92 may have a width that generally corresponds to the width of the cavity 36 and extends in an uninterrupted fashion from one side of the support structure 40 to the other side of the support structure 40. The forward compartment 92 may be substantially open to one or more of the compartments 48 that are positioned rearward of the forward compartment 92 in the cavity 36. The forward compartment 92 may include one or more rearward ledges 104 that extend from the side wall of the support structure 40 into the cavity 36. The rearward ledges 104 of the forward compartment 92 may aid in retaining items stored in the forward compartment 92. The forward compartment 92 may further include a central rib 108 that provides additional support to large items stored in the forward compartment 92. A rearward extreme of the central rib 108 may be further rearward than the rearward ledges 104 to provide additional clearance for items stored in the forward compartment 92 that have a greater width in a central portion of the item (e.g., riffles with scopes mounted thereto). A rearward extent of the central rib 108 may be defined by one of the support ribs 44 of the support structure 40. The forward compartment 92 of the cavity 36 may be recessed from a top surface of the support structure 40 and/or a top surface of the forward shelf 88. The compartments 48 of the cavity 36 may be formed by coring-away or removing sections of the support structure 40 thereby reducing the support structure 40 to the support ribs 44. The support ribs 44 may be positioned such that at least one support rib 44 is directly below a projected or calculated center or mass of an occupant of the vehicle seating assembly 28. The support ribs 44 may have a lateral thickness (i.e., parallel to the axis of rotation of the seat 32) that is in the range of at least about 10 mm to less than about 70 mm, at least about 20 mm to less than about 60 mm, at least about 30 mm to less than about 50 mm, and/or combinations or ranges thereof, including intermediate and singular values. A lower extent of the compartments 48 may be defined by a floor 112 of the vehicle 20.
Referring now to FIG. 3, the support structure 40 is shown according to another embodiment. The seat frame bar 64 that the seat 32 may pivot about is shown in partial phantom and may extend along a rearward most portion of the support structure 40. In the depicted embodiment, the positioning recesses 80 (FIG. 2) have been omitted. Accordingly, the seat 32 rests upon the support structure 40 without the aid of the positioning structures 76. The support structure 40 may include the forward shelf 88 of the cavity 36 that receives the retention ridge 72 (FIG. 2) of the seat 32. In such an embodiment, the retention ridge 72 may act as a positioning aid that properly aligns the seat 32 over the support structure 40 when the seat 32 is in the closed position. The cavity 36 may be generally symmetrical in shape. The compartments 48 of the cavity 36 may be configured with various sizes and contours. The forward compartment 92 of the cavity 36 may extend from the top surface of the support structure 40 downward to the floor 112 of the vehicle 20 (FIG. 1).
Referring to FIGS. 4-6, the seat 32 is shown in the generally horizontal closed position over the support structure 40 (FIG. 4). The vehicle seating assembly 28 may further include one or more hinge assemblies 116 that operably couple the seat 32 to a seat frame, such as the seat frame bar 64 (FIG. 3). The hinge assembly 116 may further include channels 120 and support wires 124. In operation, the support wires 124 travel within the channels 120 as the seat 32 transitions between the open position and the closed position. The channels 120 may be formed in a coupling portion 128 of the hinge assembly 116. In some embodiments, the channels 120 of the hinge assembly 116 are integrally formed with the seat 32. In alternative embodiments, the channels 120 of the hinge assembly 116 may be formed in the coupling portion 128, which may be inserted into a preformed recess 130 in an underside of the seat 32. The anti-submarine bowls 68 may be integrally formed with a larger structure, such as a support liner 132. The support liner 132 may have a vertical thickness that is in the range of at least about 1 mm to less than about 20 mm, at least about 5 mm to less than about 15 mm, at least about 8 mm to less than about 12 mm, and/or combinations or ranges thereof, including intermediate and singular values. The support liner 132 may be constructed of a glass filled polymer. The support liner 132 may carry the positioning structures 76 for the seat 32 that mate with the positioning recesses 80 in the support structure 40. The support liner 132 may include a forward compartment aperture 136.
Referring again to FIGS. 4-6, the forward compartment aperture 136 increases the storage volume available in the forward compartment 92 of the cavity 36. Additionally, the forward compartment aperture 136 may expose items stored in the forward compartment 92 directly to a cushioning material of the seat 32 such that the item stored in the forward compartment 92 may deform the cushioning material of the seat 32. The deformation of the cushioning material of the seat 32 by the items stored in the forward compartment 92 may provide several benefits, which include, but are not limited to, preventing damage to the item stored in the front compartment 92 when users occupy the vehicle seating assembly 28, providing a customized and gentle positive retention of the item stored in the forward compartment 92 during vehicle maneuvers, etc. The cushioning material of the seat 32 may have a thickness of at least about 1 mm, at least about 2 mm, at least about 3 mm, at least about 4 mm, at least about 5 mm, at least about 6 mm, at least about 7 mm, at least about 8 mm, at least about 9 mm, at least about 10 mm, and/or combinations or ranges thereof. In some embodiments, the forward compartment aperture 136 may be a forward compartment recess that does not expose items stored in the forward compartment 92 directly to the cushioning material of the seat 32. Instead, the forward compartment recess is a continuous portion of the support liner 132 that protrudes upward into the underside of the seat 32 such the storage volume available in the forward compartment 92 is increased. The anti-submarine bowls 68 are positioned to generally correspond with intended seating positions of the seat 32. The support wires 124 may be generally U-shaped and include hooked ends 140 that are positioned on either side of a central portion 144. The central portion 144 of the support wires 124 may generally resemble a towel-bar-like structure that has a substantially linear mid-section that extends outward toward the hooked ends 140 and transitions to the hooked ends 140 through a rounded turn (e.g., a rounded 90 degree turn). The support wires 124 may aid in retention of the seat 32 to the vehicle seating assembly 28 to prevent the seat 32 from sliding forward. In some embodiments, the seat 32 may further include a strap or other retention member that couples the seat 32 to the support frame of the vehicle seating assembly 28 (e.g., the seat frame bar 64).
Referring now to FIG. 7, the vehicle seating assembly 28 is shown according to an alternative embodiment. The seat 32 may transition between the open position and the closed position by pivoting about an axis defined by the seat frame bar 64. The seat 32 may be designed with a 60/40 split similar to the seatback 60 such that a user may selectively rotate the seat 32 to reveal a portion of the cavity 36 without disturbing the remaining seating positions. The seat 32 may further include a supplemental storage area 148 in the underside of the seat 32. The supplemental storage area 148 may include a retention device 152, such as netting, that aids in the retention of items stored in the supplemental storage area 148 while the seat 32 is in the open and/or closed positions. The retention device 152 may be removable from the supplemental storage area 148. The seat 32 may extend over the front wall 96 of the cavity 36 when the seat 32 is in the closed position. The extension of the seat 32 over the front wall 96 of the support structure 40 may be referred to as a waterfall seat structure 154. In the depicted embodiment, the cavity 36 may include a sloped structure 156 that directs items stored in the cavity 36 rearward of the front wall 96 such that the items stored in the cavity 36 are prevented from exiting and/or falling out of the cavity 36 when the seat 32 is in the open and/or closed position. For example, the sloped structure 156 may help retain the items stored in the cavity 36 during vehicle maneuvers.
Referring again to FIG. 7, the forward compartment 92 of the cavity 36 may be located immediately rearward of the sloped structure 156 for storing long items. The additional compartments 48 of the cavity 36 may be located on vehicle outboard sides of the sloped structure 156 and/or rearward of the forward compartment 92. In some embodiments, the sloped structure 156 may be located in a central location of the cavity 36 such that the compartments 48 surround the sloped structure 156. In such an embodiment, items stored in the cavity 36 are encouraged to roll or shift towards the walls of the cavity 36 by the sloped structure 156. In alternative embodiments, the sloped structure 156 may be offset from the front wall 96 of the support structure 40 such that the forward compartment 92 of the cavity 36 is positioned between the sloped structure 156 and the front wall 96. In such an embodiment, the sloped structure 156 may have a substantially vertical forward wall such that a cross section of the forward compartment 92 is substantially rectangular. A lower surface 160 of the cavity 36 may be integrally formed with the support structure 40 rather than being defined by the floor 112 of the vehicle 20 (FIG. 3), as in some previous embodiments. The supplemental storage area 148 of the seat 32 may be generally recessed into the underside of the seat 32.
Referring to FIG. 8, the vehicle seating assembly 28 is shown with the seat 32 in the open position, according to another embodiment. The support ribs 44 of the support structure 40 may be provided with one or more slots 164. The slots 164 may be positioned in some or all of the support ribs 44. The slots 164 may serve the function of the forward compartment 92 in previous embodiments. That is, the slots 164 in the support ribs 44 may enable the storage of longer items in the cavity 36. For example, one or more riffles may be stored in the slots 164. The slots 164 may extend from a top surface of the support ribs 44 to the lower surface 160 or the floor 112. Alternatively, the slots 164 may extend from the top surface of the support ribs 44 downward to a depth in the support rib 44 that retains at least a portion of the support rib 44 below the slots 164. The compartments 48 of the cavity 36 are generally positioned between the support ribs 44 and the walls of the support structure 40. The compartments 48 may be of various sizes and contours. In some embodiments, the vehicle seating assembly 28 may be equipped with a prop bar 168 that is operably coupled to the seat 32. The prop bar 168 may be additionally coupled to the support structure 40. Alternatively, the prop bar 168 may be directly coupled only to the seat 32. In another alternative, the prop bar 168 may be directly coupled only to the support structure 40. In some embodiments, the prop bar 168 automatically deploys when the seat 32 is placed in the open position such that the seat 32 remains in the open position and is prevented from unintentional closing while a user is accessing the cavity 36. In other embodiments, the prop bar 168 may be manually deployed by a user when the seat 32 is placed in the open position. In general, the prop bar 168 is configured to provide a brace that supports the weight of the seat 32 when the seat 32 is in the open position. For example, the prop bar 168 may be in physical contact with the seat 32 and the support structure 40 to provide the resistance to unintentional closure of the seat 32 while the user is accessing the cavity 36. In various embodiments, the prop bar 168 may engage with a detent or recess in the seat 32 or the support structure 40 to provide the resistance to unintentional closure of the seat 32. The prop bar 168 may be, for example, a gas piston. In the depicted embodiment, the seat 32 extends over and around the walls of the support structure 40 when the seat 32 is in the closed position. Said another way, the support structure 40 is configured to nest within exterior walls of the underside of the seat 32.
In the various embodiments discussed herein, the vehicle seating assembly 28 may be equipped with a lock that allows the user to safely and securely store items in the cavity 36 by locking the seat 32 in the closed position. The lock may take various forms which include, but are not limited to, a keyed lock, a combination lock, a biometric recognition lock, and the like. While the seat 32 has been depicted as opening in a rearward direction by pivoting upwards towards the seatback 60, it is contemplated that in alternative embodiments the cavity 36 may be accessed by opening the seat 32 in an upward direction away from the seatback 60. In such an embodiment, one or more brackets or hinges may be provided on the front wall 96 of the support structure 40 that operably couple the seat 32 to the support structure 40 in a pivotable fashion without departing from the concepts disclosed herein. In some embodiments, the top surface of the support structure 40 and/or the support rib 44 may include a “skin” that is grained with a predetermined pattern. The predetermined pattern may be, for example, a carbon fiber pattern, a leather pattern, or the like. The skin may be directly formed on the top surface of the support structure 40 and/or the support rib 44 rather than being a separate portion. The predetermined pattern of the skin may be aesthetically pleasing to the user such that the material that the support structure 40 and/or the support rib 44 are made of may be exposed when the user accesses the cavity 36. Accordingly, manufacture of the vehicle seating assembly 28 may be simplified. Additionally, the skin may increase the strength and rigidity of the support structure 40 and/or the support ribs 44.
The support structure 40 of vehicle seating assemblies 28 is often an important aspect in providing occupant safety during impact events, such as vehicle collisions. Therefore, the support structure 40 is often provided as a continuous member in the seat 32. However, the present disclosure provides a storage bin in the form of the cavity 36 that is created by reducing or removing a substantial portion of the support structure 40 while meeting anti-submarining and frontal crash dynamic integrity requirements. Additionally, the comfort of the occupant of the vehicle seating assembly 28 may remain unchanged as a result of the decrease in supporting material. The storage bin may be utilized for storing any number of items, including, but not limited to, an ice scraper, additional clothing, shoes, emergency kits, sporting equipment, etc.
