Description:
FIELD 
   The inventive embodiments are directed towards vehicular seating. More particularly, the inventive embodiments relate to a storable and easily removable jump seat for use in vehicles such as vans and sports utility vehicles. 
   BACKGROUND 
   Vans and sport utility vehicles (“SUVs”) have become a popular means of transportation partly because of their flexibility and multi-faceted utility. For example, a van may on one occasion be utilized to transport a number of passengers and on another occasion be used to transport a variety of cargo, or even a combination of both. Because of the demands on the versatility of such vehicles, it has become a fairly common practice to design a vehicle&#39;s rear seats so they can be converted, folded, stored or removed in order to extend the amount of cargo space available. Some seating arrangements are more accommodating than others. Some are designed to engage the floor until released, enabling them to be removed from the vehicle for storage. Other designs provide rollers to assist the user in removing the seating arrangement from the vehicle. Thus, given enough notice, a user needing to extend the available cargo space in a vehicle may remove seating in advance of picking up and loading the cargo. 
   However, in a fast-paced and hyperactive society, it is not always possible to plan far enough ahead of time to remove a vehicle&#39;s seating to convert the space for cargo. In some situations a driver may have to turn down opportunities to pick up and transport cargo because the need arose while the driver was away from home, that is, somewhere where it was impractical to remove the rear seating and securely store it. The designers of automobiles have partially accommodated this dilemma by making the seats in some vans and SUVs foldable toward the front of the cargo space, storable in the floor body or foldable against the wall of the vehicle. However, those designs that provide for a convertible seating in the form of a folding jump seat generally face problems concerning appearance, comfort, safety and practicality. Some of the seating that is storable within the vehicle remains coupled to the floor during storage, thereby obstructing a portion of the floor space. Therefore, it is desirable to have a safe, comfortable and easily storable seat that may be folded and stored within the cargo area of a vehicle to expand the cargo space and maximize floor space while also being quickly and easily removable in order to maximize the total available cargo space. Likewise it is desirable to have that same seating arrangement be quickly and easily reinstalled by the consumer without the need for tools or additional assistance. 
   SUMMARY 
   According to one aspect, a manifestation of the inventive embodiments provides a seat for selective engagement with the floor of a vehicle and releasable storage against an inside wall of a vehicle. The seat includes a seat base with a foot coupled to the bottom of the seat base for supporting a portion of the seat base upon the floor and having an engaging means for releasably engaging the floor. A seat striker assembly is mounted to an inside wall of the vehicle on the side of the seat substantially opposite the foot and is fitted with at least one seat striker member. The seat includes a hinge lock assembly for hingedly supporting the seat base against the wall and provided with at least one hinge lock for releasably engaging the seat striker member to secure said hinge lock assembly to said vehicle wall when engaged. The hinge lock assembly also provides the pivoting axis when the seat is being raised and lowered from its storage position against the wall. Located in an area preferably under the seat base, is an actuable floor lock release means for disengaging the foot from the vehicle floor when the release means is actuated. Upon actuation, the seat may be then rotated toward and stored substantially against the vehicle wall until returned to its operating position. 
   According to a further aspect, an inventive embodiment provides for a manually removable seat for selective engagement with the floor of a vehicle and releasable storage against an inside wall of a vehicle. In this embodiment, the seat has a seat base having an internal frame. Mounted to the floor is a floor striker assembly fitted with at least one striker. The seat includes a foot hingedly coupled to the seat frame for supporting a portion of the seat base upon the floor. The foot may also be provided with at least one lock for releasably engaging the at least one striker member for securing the foot to the floor body when the seat is installed. The foot is preferably foldable within the seat base when the seat is in its stored position. On the other side of the seat base, a seat striker assembly is mounted to an inside wall of the vehicle and is fitted with at least one seat striker member. A hinge lock assembly having at least one hinged extension is coupled to the seat frame and is configured to support one side of said seat base against the wall and to provide the pivoting axis for storing the seat. The hinge lock assembly is provided with at least one hinge lock for releasably engaging the seat striker member for securing one side of the seat base when the hinge lock assembly is engaged. An actuable floor lock release means is coupled to the foot for disengaging the lock from the floor striker member when the release means is actuated, allowing the seat to be rotated toward and stored substantially against the vehicle wall. 
   Yet another aspect of the inventive embodiments provides for a manually removable seat in a vehicle wherein the seat is removably disengaged from the vehicle floor and vehicle wall upon actuation of both a floor lock release means and a hinge lock release means. 
   Another aspect of the inventive embodiments provides for a seat, having a seat base, for selective engagement with the floor of a vehicle and being pivotable into a storage position substantially against an inside wall of the vehicle, wherein the seat is completely disengaged from the floor when in the storage position and the seat is pivotable about an axis located substantially parallel to the floor and spaced above the floor at least as high as a top surface of the seat base. 
   Yet another aspect of the inventive embodiments provides for a manually removable seat for selective engagement with the floor of a vehicle and being pivotable into a storage position substantially against an inside wall of the vehicle, wherein the seat is completely disengaged from the floor when in the storage position and is pivotable about an axis substantially parallel to both the floor and the wall. 
   Yet another aspect of the inventive embodiments provides for a manually removable seat in a vehicle that is easily and quickly stored against an inside wall of a vehicle, easily and quickly reinstalled onto the floor of the vehicle or easily and quickly removed from the vehicle completely depending upon the amount of cargo space desired. 
   Still another aspect of the inventive embodiments provides for a storable jump seat that maximizes the amount of floor for cargo. 
   It is to be understood that both the foregoing general description and the following detailed description are exemplary only and are not restrictive of the inventive embodiments, as claimed.

   DETAILED DESCRIPTION OF THE INVENTION 
   Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like components. 
   With reference to  FIGS. 1A and 1B , a removable seat, which may also be referred to as a jump seat, as embodied herein, is designated by the numeral  10 . For the purpose of clarity and to expose the structure of seat frame  70 ,  FIG. 1B  depicts seat  10  in substantially the same view but without cushions in the seat base  72  and seat back  74  areas. The seat  10  in substantially the same view but is shown having a substantially rectangular seat base  72  upon which a passenger may be seated. The seat base  72  preferably comprises a cushioned surface supported by seat frame  70  and may be covered in any number of different materials, such as natural or synthetic fabrics, leather or plastic, depending upon the taste of the consumer and the intended use of the vehicle. Pivotably coupled to the rear of the seat base  72  is seat back  74  which is preferably of a similar construction as the seat base. Seat back  74  is designed to pivot backwards at its junction with the seat base  72  in stages towards a substantially reclined position for passenger comfort or in preparation of folding the seat  10  into its storage position, as shown in FIG.  5 . The pivoting of the seat back  74  into a reclined position may be accomplished by the actuation of seat back release pull  94 , which may be constructed of a webbed fabric loop, rope or other release mechanisms known in the art. Seat back release pull  94  may be coupled to seat back release mechanism  95 , which, when actuated, provides for adjustment of the vertical angle of the seat back  74 . A seat back return mechanism  75 , such as a coiled spring or the equivalent, may be provided to bias the seat back  74  in a forward direction to assist a passenger in returning the seat back to its full upright position. For the comfort and safety of a passenger, seat back  74  may also be fitted with a head rest  76 , which may adjusted to suit the physiology of a passenger. 
   A center console  98  may be provided on upper surface of the seat base  72  near one side as a convenience for the passenger and may be optimized to hold cups, coins or other items typically used by passengers. The center console  98  may also be located on the upper surface of seat base  72  toward the side nearest the center of the vehicle which has the additional benefit of discouraging passengers from sitting on this portion of the seat base. A foot  78  is coupled to seat base  72  at one side of seat  10  and provides spaced support for the seat base upon the body floor  81  as well as locking means and releasing means for releasably engaging the floor. “Releasable,” “Releasably,” “Detachable” and “Detachably” are used interchangeably herein with regard to engagement to connote complete disengagement between two members. The foot  78  is preferably pivotably coupled to seat base  72  at pivot point  79  to allow for the foot to be folded inwardly toward the seat base upon rotation of the seat  10  into its stored position. Foot  78  may be provided with front and rear foot locks (not shown in detail) as known in the art, for locking engagement with one or more strikers, such as front and rear floor striker members  82  and  84 , which are fixedly coupled to body floor striker assembly  80 , which in turn, is fixedly coupled to body floor  81 . In this manner, foot  78  is removably anchored to the body floor  81  and provides for secure mounting of one side of seat  10  when installed. Captive front and rear floor striker members  82 ,  84  may be released from their respective locking members via actuation of lock release pull  86 , which is preferably of a similar construction as seat back release pull  94 . Upon release of the foot  78  from the body floor striker assembly  80 , seat  10  is free to be either pivoted into a stored position or removed completely from the vehicle upon the additional disengagement of hinge lock assembly  40  from seat striker assembly  12 . Details of this operation will be discussed below in conjunction with  FIGS. 2-4 . Front and rear damper feet  88  and  90  may be provided on the bottom surface of foot  78  for contact with the facing surface of body floor striker assembly  80  to add stability to seat  10  when installed, reduce strain on the front and rear floor striker locks, as well as to provide a resilient surface upon which to rest the jump seat when it has been removed from the vehicle. The exposed (outer) surface of foot  78  may be covered with a fitted, decorative fascia, or garnish (not shown) for appearance and safety sake. The fascia serves no other operational purpose and has been omitted from the figures in order to show other details of the foot. It will also be understood by one of ordinary skill in the art that this embodiment is merely an example. Instead of using two lock and striker combinations, as at  82  and  84 , any other number of lock and striker combinations may be used provided they are effective to secure the seat  10  to the body floor  81 . In addition, other types of removable securing means, such as screws or bolts, could be used instead of a lock and striker mechanism. The person of ordinary skill in the art is able to select an attachment structure having sufficient strength to secure the seat  10  to the vehicle, while still enabling a user to easily release the securing mechanism, for removing or stowing the seat preferably without the need for separate tools. In addition, while the foot  78  is shown as being placed adjacent one side of the seat base  72 , it will be understood that the foot may be positioned at other locations on the seat base, such as along the front, back, or middle of the seat, or diagonally, provided the seat exhibits sufficient strength to adequately and safely support a seated passenger. 
   With continuing reference to  FIG. 1B , seat striker assembly  12  is shown mounted to the vehicle wall  31  in the area above wheel well  34 . However, it should be appreciated that this particular mounting scheme may vary as the seat  10  is adapted to other environs or structures without detracting from the invention. A support bracket  32  affixed to the vehicle wall  31  in the area proximate the door jamb  30  may be provided to secure seat striker assembly  12  to the body of the vehicle. Additional mounting brackets, such as at  24 , may be incorporated into seat striker assembly  12  and coupled to the vehicle wall  31  with bolts, as at  28 , to provide additional structural support for the seat striker assembly. Hinge lock assembly  40  is shown generally in this view being engaged with seat striker assembly  12 . Additional details of these assemblies will likewise be discussed in conjunction with  FIGS. 2-4 . The exposed (outer) surfaces of seat striker assembly  12  and hinge lock assembly  40  may be covered with a fitted, decorative fascia, or garnish (not shown) for appearance and safety sake. The fascia serves no other significant operational purpose and has been omitted from the figures in order to show other details of the two assemblies. 
   Referring now to  FIGS. 2-4 , hinge lock assembly  40  and seat striker assembly  12  are shown in detail.  FIGS. 2 and 3  show the two assemblies  12 ,  40  disengaged, whereas  FIG. 4  depicts them in their fully engaged and locked configuration. Looking to  FIG. 2 , seat striker assembly  12  is shown to comprise a structural channel  18  to which anchoring extensions, such as at  20 ,  22  and  24 , may be affixed to provide a means for mounting the seat striker assembly to the vehicle wall  31  or equivalent structure. In the embodiment shown, the seat striker assembly  12  is mounted to a support bracket  32 , the face of door jamb  30  and the upper surface of wheel well  34  via bolts, as at  28 , or other, preferably removable, mounting means as known in the art. Front and rear seat strikers  14  and  16  are affixed to structural channel  18 , typically by welding or other rigid securing means. Lateral stabilizer bracket  15  is also affixed to the structural channel and is located intermediate the front and rear seat strikers  14 ,  16 . Lateral stabilizer bracket  15  may be configured in a “vee” shape corresponding to its mating complement, stabilizer bumper  62 , mounted to the hinge lock assembly body  44  of hinged lock assembly  40 , although other shapes would function equivalently to provide lateral stability between the seat striker assembly  12  and hinge lock assembly. Lastly, stopper brackets, as at  26 , having a flat surface corresponding with the top surface of structural channel  18 , may be strategically affixed to the side of structural channel to provide additional surface area for the hinge arm mounting brackets, as at  45 , to rest upon. In this regard, the stopper bracket  26  lessens the amount of stress on structural channel  18  while the hinge lock assembly  40  is engaged with seat striker assembly  12  and the seat  10  is rotated about pivot line P L . A locking cap  64  is provided at the bottom of the hinge lock assembly body  44  to prevent the separation of components of hinge lock assembly body as the seat  10  is rotated about pivot line P L . 
   Referring next to  FIG. 3 , details of the hinge lock assembly  40  can be seen. Hinge lock assembly body  44  is shown to be configured with two seat striker engaging areas, the hook mouth  43  of front hook  42  and the hinge lock mouth  47  of rear lock  46 . Pivotably coupled to front and rear hinge arm mounting brackets, as at  45 , the front bracket being shown extending from the face of hinge lock assembly body  44 , are front and rear hinge arms  54  and  56 , which in turn, are rigidly affixed to a portion of seat frame  70 , shown in phantom in FIG.  3 . Front and rear hinge arms  54 ,  56  (and thus the entire seat assembly  10 ) are pivotable about pivot line P L  when the foot  78  is disengaged from body floor striker assembly  80 . A damper  60  may be employed which is preferably mounted to the face of hinge lock assembly body  44  and coupled to at least one of the hinge arms  54 ,  56 . The damper  60  may be of an oil-filled variety or may be a coiled spring assembly or the equivalent. In a preferred embodiment, damper  60  either assists or provides no resistance to the upward movement of the seat  10  into its stored position. However, when the seat  10  is lowered into its operating position, damper  60  preferably provides adequate resistance in the downward pivoting direction to prevent the jump seat from rotating too quickly as it is being lowered. 
   The present invention is illustrated with the preferred lock and hook assemblies  46  and  42  and two strikers  14  and  16 . However, as should be appreciated by those skilled in the art, any number of locks and strikers may be used, provided that the lock and striker are designed with adequate strength. Additionally, two locks may be used instead of the preferred lock and hook assembly. The lock and hook configuration, as depicted, is preferred for ease of use by a vehicle user. 
   Hinge lock release lever  49  is pivotably coupled to the face of hinge lock assembly body  44  and mechanically coupled to rear lock  46 . Lock release lever knob  48  is provided at the end of release lever  49  to aid in its manual actuation. Upon actuation of hinge lock release lever  49  to position “B”, (rotating it forward, to the right in this configuration), rear lock  46  is withdrawn, thus enabling disengagement of previously engaged assemblies  12  and  40 . Details of the operation of the rear lock  46  from a striker, such as at  16 , is clearly understood by those in the art and will not be described in detail here. Also pivotably coupled to hinge lock release lever  49  is interlock bracket  50 , which pivots from its resting position, shown in  FIG. 4 , to its operational position, shown in  FIG. 3 , when hinge lock lever is in its “released” position, i.e., rotated forward. When in this position, interlock bracket  50  confronts rear hinge arm  56  at about point “P” and obstructs it, thus preventing it and everything else coupled to it, namely the entire seat assembly  10 , from rotating about axis P L  when removed from its operational position. Thus, when seat  10  is disengaged from the floor body  81  and wall  31  of the vehicle, the hinge lock assembly  40  is maintained in substantially the same orientation as when engaged with seat striker assembly  12 , being prevented from rotating in relation to the seat base  72 . As such, the hinge lock assembly  40  remains in a “released and ready” position until such time as seat  10  is reinstalled in the vehicle. A lift handle  52  may be coupled to hinge lock assembly body  44  to assist the user to manipulate seat  10  during its installation and removal. A lift handle  96  may be provided at the upper surface of seat base  72  towards the center of the vehicle to assist the user in manipulating seat  10  during its installation, storage and removal. Lift handle  96  is preferably constructed in the form of a loop from a flexible material, such as webbed fabric or a resilient plastic, although other materials and configurations may be equally well suited for the intended purpose. 
   Referring now to  FIGS. 1-4 , the installation of the seat  10 , according to one embodiment of the invention will be described. With both the hinge lock assembly  40  and the foot  78  in their vertical, operational positions, the seat  10  is guided into the vehicle in the area it is to be installed. Preferably, hinge lock assembly  40  is first engaged with seat striker assembly  12  by guiding the hook mouth  43  of front hook  42  within structural channel  18  to engage front seat striker  14 . Once front seat striker  14  is engaged, the rear of the seat  10  is lowered until the rear seat striker  16  is aligned with rear hinge lock mouth  47 , and then the rear of hinge lock assembly  40  is pressed downward until rear lock  46  engages the rear seat striker. Upon engagement of both front and rear seat strikers  14  and  16 , hinge lock release lever  49  is rotated to its “locked” position “A” (rotated rearwardly, to the left in this configuration), thus securing the pivotable hinge lock assembly  40  to the seat striker assembly  12 . Actuation of hinge lock release lever  49  to its locked position releases the interlock bracket  50  from confronting rear hinge arm  56 , now enabling seat  10  to pivot along axis P L . Once the hinge lock assembly  40  is secured, seat  10  is maneuvered such that the front and rear locks (similar to that at  46  but not shown in detail) of foot  78  are aligned over front and rear body floor strikers  82  and  84 . After being aligned, the edge of seat base  72  in the area over the foot  78  may be pressed downward to engage the floor strikers  82  and  84  within the front and rear locks of the foot. This completes the installation procedure of seat  10 . 
   Referring now to  FIGS. 1A ,  1 B and  5 , the operation of moving seat  10  into a stored position as shown in  FIG. 5 , will be described. Beginning with the seat  10  in its operational position, as shown in  FIG. 1A , seat back  74  is placed in a substantially fully reclined condition by actuation of seat back release pull  94 . Once in a substantially fully reclined position, the user releases seat back release pull  94  whereby the seat back release mechanism  95  re-engages and maintains seat back  74  in the substantially fully reclined condition. Once the seat back  74  is in position for storage, foot  78  is released from the body floor striker assembly  80  by actuation of foot release pull  86 . Upon actuation of foot release pull  86 , both front and rear foot locks (not shown in detail) disengage from front and rear body floor strikers  82  and  84 . Once foot  78  is fully disengaged from the body floor striker assembly  80 , the now reclined seat  10  may be rotated about axis P L  towards its storage position. In a preferred embodiment, axis P L  is substantially parallel to both the vehicle floor  81  and the vehicle wall  31 . Upon rotation of seat  10  to a position substantially face to face with vehicle wall  31 , jump seat latch  92  may be used to engage a wall mounted anchor means, such as grab rail  100 . Once the seat  10  is in its stored and locked conditions, as shown in  FIG. 5 , the cargo area in the vehicle has now been expanded and available for non-passenger use. Note that in this embodiment, the entire floor area is available for utilization, including cargo storage. 
   Seat  10  has been described and depicted as a single seating unit on the driver&#39;s side of a vehicle. However, it is anticipated that embodiments of the invention may be employed in more than one location within a vehicle, such as in a side by side orientation to form a second row of seating behind the vehicle&#39;s front seats. It is also anticipated that the described embodiments of the invention may be adapted for use in other structures other than vehicles, such as building structures where there may be a need for removable and storable seating. 
   It will be apparent to those skilled in the art that various modifications and variations can be made in the removable jump seat for a vehicle according to the invention disclosed herein, as well as in its construction, without departing from the scope or spirit of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims:
