BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lightweight, easy to carry booster seat for a child or a small adult, particularly suited for theater and sporting events.
2. Description of Related Art
Small children have difficulty seeing theatrical performances, movies, and sporting events while seated in the typical theater and stadium seats because they can not see over the seat in front of them. Further, these children are not properly supported in seating designed for adults, and can even slip out of their seats if they slouch or kneel, leading to possible injuries.
While booster seats are widely used to raise children above the adult's seats, most of them are bulky and awkward to carry. There are some collapsible seats known in the art, which are easier to transport than rigid booster seats. However, even these collapsible seats can be a burden to carry especially in heavy crowds often encountered at sporting events. Thus, a lightweight, compact, and easily carried booster seat is desirable.
BRIEF SUMMARY OF THE INVENTION
The present invention is a non-freestanding booster seat for use with a stadium seat, i.e., a seat of the type often used in theaters and stadiums. A stadium seat comprises a seating member, a backrest member, and a support, wherein the seating member folds up against the backrest member.
In a first embodiment of the booster seat that is especially suited to a stadium seat having a slatted backrest member, the means of attaching the sheet comprises two or more sets of straps. Each set of straps comprises two straps, wherein one strap passes over a slat in the backrest member and the other strap passes under the slat so that when the two straps are joined the seat is attached to the backrest member. The straps may be joined by any means known in the art such as tying or buckling. The back surface of the seat, at the bottom, is fitted with a sleeve capable of fitting around the outer edge of the seating member of the stadium seat when the stadium seat is in its folded position.
In a second embodiment that is substantially the same as the first embodiment except that the means of attaching the sheet to the backrest member of a stadium seat comprises one or more hooks affixed to the back of the sheet, at or near, it's top. This embodiment may be used with substantially all stadium seats.

Thus, the appearances of such phrases or in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments without limitation.
The term “or” as used herein is to be interpreted as an inclusive or meaning any one or any combination. Therefore, “A, B or C” means any of the following: “A; B; C; A and B; A and C; B and C; A, B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.
Typically, theaters, auditoriums, and sports venues, e.g. stadiums, gymnasiums, field houses, etc., are fitted with seats joined together at their sides or bottoms to form longs rows of seats, referred to herein collectively as “stadium seats.” Stadium seats have a seating member, a backrest member, and a supporting base, which is typically affixed to the floor. To facilitate movement of patrons in and out of their seats, stadium seats referred to herein are constructed so that the seating member can be folded toward the backrest member by pivoting on the supporting base when the seat is not occupied. In some cases, the backrest member and seating members of stadium seats are constructed of slats with gaps between the slats. In other cases, the backrest members and seating members are solid. Provided herein is a booster seat for a child or a small adult having embodiments and options suitable for use with either slatted-back stadium seats, solid back stadium seats, or both.
FIGS. 1a and 1b show a first embodiment, seat 10, of the present invention. FIG. 1a depicts seat 10 laying flat with its back down and front facing toward the viewer while FIG. 1b depicts the right side view of FIG. 1a. In this embodiment, seat 10 is a substantially rectangular sheet of flexible material, such as fabric, netting, leather, or polymeric film, having a front 10a, a back 10b, a top 10c, a bottom 10d, a left side 10e, a right side 10f, a left, bottom corner 12a and a right, bottom corner 12b. 
The bottom corners 12a and 12b are connected to their respective side, i.e., left side 10e and right side 10f (collectively, “the sides”) at substantially the same distance from the bottom 10d by connecting means such as straps, ropes, wires, strips of leather, and strips of fabric, collectively referred to herein and illustrated in FIGS. 1a and 1b as “side straps” 14. One end of each of the side straps 14 may be attached to the sides, i.e., one end on each side as illustrated in FIGS. 1a and 1b, at any point in the range from about midway along each side to the top 10c. Preferably, the side straps 14 are attached to the sides about 10% to about 35% of the distance between the top 10c and the bottom 10d with respect to the top 10c. Also within the scope of the invention, the side straps 14 may be attached to the side by an adjustable means so that the user of the seat can choose the point of attachment of the side straps 14 to the sides. The other end of each of the side straps 14 is affixed to one of the bottom corners 12a and 12b as shown in FIGS. 1a and 1b. 
While each of the side straps 14 may be a fixed length, preferably each is fitted with a means of easily adjusting its length. As illustrated in FIGS. 1a and 1b, each of the side straps 14 may be comprised of a set of two straps 14a and 14b that are joined preferably by a fastening means, such as a buckle 18 having a means of easily adjusting the length of the straps 14a and 14b. 
Seat 10 may be connected to a slatted-back type stadium seat by connecting means such as straps, ropes, wires, and the like collectively referred to herein and illustrated in FIG. 1b as “back straps” 16. FIGS. 1b and 1c illustrates back straps 16 as being comprised of a set of two straps 16a and 16b. Seat 10 is fitted with at least two back straps 16 as illustrated in FIG. 3c. Typically, straps 16a and 16b are passed through adjacent openings between slats in the slatted-back stadium seat and joined by a fastener such as a buckle 18 or tied together, thus securing the top of the seat to the top of the backrest member of the slatted-back seat. Preferably, straps 16a, 16b, or both are fitted with a means of easily adjusting the length of the straps.
A sleeve 19 in the form of a pocket, substantially the width of the seat 10, is affixed to the back 10b along the edge of bottom 10d with the opening of the sleeve 10a facing toward the top 10c. The sleeve 19 is preferably fabricated from an elastic material that allows the sleeve 19 to expand or contract to snuggly fit around the front edge of the seating member of a stadium seat (i.e. the distal edge with respect to the backrest member). Further, a snug fit around the edge can be achieved by strapping with a means of adjustment such as a buckle or any suitable adjustment device of the art.
Alternatively, as shown in FIG. 1d, in place of sleeve 19 as the means of attaching seat 10 to the seating member of the stadium seat, one or more hooks 19a may be affixed to the back 10b, at the bottom 10d, of seat 10. Such hooks 19a are attached around the distal edge of the seating member in a way analogous to the attachment of sleeve 19. If only one hook is used, it is preferable that it be a relative wide hook, centered, and extending substantially the length of the bottom 10d of seat 10. If the seating member of the stadium seat is slatted, one or more set of straps 19b, see FIG. 1e, (including, but are not limited to, ropes, wires, strips of leather, and strips of fabric, collectively referred to herein as “straps”) may be affixed to in place of sleeve 19 to a slat at the distal edge of the stadium seat. Such straps may be fastened by tying, buckling, and the like around the slat at the distal edge of the stadium seat in a way analogous to the attachment of straps 16 to a backrest member of a stadium seat described herein above.
FIG. 1f illustrates the seating member of the stadium seat being raised while seat 10, with its top attached to the backrest member, is being pulled outward so that sleeve 19 may be fitted over the edge of the seating member. The side straps are then adjusted to provide a pocket illustrated below in FIG. 3b. 
FIGS. 2a-2c show a second embodiment of the seat of the present invention. FIG. 2a depicts the seat 20 that corresponds to seat 10 of FIGS. 1a and 1b. Note that the first and second embodiments differ in their means of attachment to the stadium seat and the two are substantially the same in other respects. Thus, with the exception of the means of attachment, the descriptions of the features of the second embodiment are substantially the same as for the corresponding features of the first embodiment. FIG. 2a shows seat 20 laying flat with its back 20a down and front 20b facing toward the viewer. In this embodiment, seat 20 is a substantially rectangular sheet of flexible material, such as fabric, netting, leather, or polymeric film, having a top 20c, a bottom 20d, a left side 20e, and a right side 20f. 
FIG. 2b depicts the seat as viewed from its left side 20e. The top corners are joined to the respective bottom corners by side straps 24 which are similar in form and function to side straps 14 (shown if FIGS. 1a and 1b) of the first embodiment. Like the side straps 14, each side straps 24, may be comprised of two sections as shown in FIGS. 2a-2c and 3b as strap sections 24a and 24b that may be joined with an adjustable buckle 25 (or similar means known in the art) or a single strap having a means of adjusting its length. Seat 20 may optionally be fitted with a restrainer strap substantially the same as restrainer strap 22 of the first embodiment (see FIG. 1a).
A sleeve 28 (corresponding to sleeve 19 of the first embodiment shown in FIG. 1c) in the form of a pocket, substantially the width of the seat 20, is affixed to the back 20b along the edge of bottom 20d with the opening of the sleeve 28a facing toward the top 20c. The sleeve 28 is preferably fabricated from an elastic material that allows the sleeve 28 to expand or contract to snuggly fit around the front edge of the seating member of a stadium seat (i.e. the distal edge with respect to the backrest member). Further, a snug fit around the edge can be achieved by strapping with a means of adjustment such as a buckle or any suitable adjustment device of the art. Alternatively, hooks or straps may be employed in lieu of the sleeve in a manner analogous to that described above herein for the first embodiment as illustrated in FIGS. 1d and 1e. 
A means of attaching the top of the seat 20 to the top of the backrest member of a stadium seat is affixed to the top of seat 20. Conveniently, this means of attachment may be one or more hooks 30 or similar devices on the back 20b, at the top 20c, as shown in FIGS. 2a-2c. Observe that corresponding seat 10 of the first embodiment attaches to the backrest member of a stadium seat with two or more sets of straps.
FIG. 2c is a perspective view of the back of seat 20 more clearly showing the open 28a of sleeve 28, and hooks 30. For this illustration, four hooks are shown but the number of hooks may be one or more. If only one hook is used, it is preferable that it be a relatively wide hook, centered and extending substantially the length of the top 20cof seat 20.
FIG. 2c also illustrates that the hooks 30 may be affixed to seat 20 by an adjustable means to allow the hooks to be moved individually to conform to any curvature in the top of the stadium seat to which seat 20 is attached. Such a means of adjustment may be sleeves 31 affixed to the back of seat 20 through which the hook shanks 30a may pass freely but having a locking device 33 to lock the hooks 30 in desired positions. The hooks 30 may be attached by a means that also allows detachment of the hooks 30.
FIG. 3a shows a side view of a typical stadium seat 34 that has a seating member that can pivot from a “down” position 34a, for use, to an “up” position 34b when not in use. Both embodiments of the present booster seat are particularly suited for employment with this type of stadium seat with its seating member in the up position 34b. FIG. 3b is a perspective view of the present booster seat 10 with its top affixed to slatted backrest member of a slatted-back stadium seat. Although not expressly illustrated, the skilled artisan will recognize from the foregoing teaching, seat 20 would be applicable if the stadium seat back were not slatted.
As the bottom 10d or 20d, referring to the first and second embodiments respectively, is moved away from, the backrest member 36 of the slatted-back stadium seat, a fold, i.e., a pocket 38 is created in which a child may sit. The height to which pocket 38 is elevated above the seating member of the stadium seat may be altered by raising or lowering the point at which the back straps 16 are affixed to the backrest member of the slatted-back seat, or by adjusting the length of side straps 14, or both.
Optionally, Seat 10 and seat 20 may be fitted with a seat belt such as that shown if FIGS. 1a and 1a as restrainer strap 22. There may be occasions when the child must be removed very quickly form the seat to prevent injury. For example, at a baseball game, a child would need to be jerked to safety if a foul ball was headed toward the child. Therefore, if the optional restrainer strap 22 is employed, it must have a means of being quickly released. For example, the strap may be made of two parts fastened with a hook and fabric system such as the Velcro (trademark) fastening system.
The present booster seat in each embodiment may be rolled or folded to facilitate carrying it. For example, seat 10 or seat 20 may be rolled with back straps 16 facing outward so that they may be use to fasten seat 10 or seat 20 to a person's belt, purse straps, or similar items for hands-free carrying.
Additionally, a panel of flexible material may be attached to the top 10c or 20c and draped over the back of the seat (not shown in the figures). The additional panel might be imprinted with an advertisement, expression, or team logo. For example, a business may wish to promote its enterprise by giving to patron's child seats of the present invention imprinted with its commercial message.
The flexible material, which comprises the present booster seat, may be any material used in the art for making seating, harnesses, and the like. It could be used for a child or small adult. Conveniently, fabric, netting, leather, polymeric film or combinations thereof may be used so long as the material is sufficiently strong to safely support the user. Preferably the material is lightweight, water resistant, and easily cleaned. For example, nylon and light canvas fabrics are suitable for the seat. Conveniently, the seat is substantially rectangular, but other shapes such as oval and “hourglass” are within the scope of the present invention. The exact shape and proportions may vary depending on the weight and size of the child, which the seat must accommodate. For example, a small seat would be suited to a toddler, but an older child would require a larger and stronger seat.
Typically, points of wear and stress may be reinforced and edges may be hemmed to prevent unraveling and minimize wear. Where hooks are used to attach the booster seat, preferably, those hooks are fitted with tip covers of rubber, plastic, or similar relatively soft material to prevent injuries to the users of the seat and damage to the stadium seat.
As noted above, the back straps 14, side straps 16 and retaining strap 22, collectively “straps”, may be fabricated from ropes, wires, strips of leather, strips of fabric, and the like. Typically, straps of woven nylon, canvas, or leather may be used. The straps may be joined to the seat by any suitable means of the art including gluing, riveting, stitching or combinations thereof so long as the seat can support a child or adult. The ends of the straps not affixed to the seat may be joined with any suitable coupling device of the art, such as buckles, hook and fabric fasteners (e.g. Velcro (trademark) fasteners), snaps, ties, or combinations thereof so long as the seat can support a child or adult. Buckles of high strength polymer having an integrated means of adjustment (e.g. Fastex (trademark) buckles) are particularly convenient.
