referring now to the drawings wherein the showings are for purposes of illustrating preferred embodiments of the present invention only , and not for purposes of limiting the same , fig1 perspectively illustrates a two - stage seat cover 10 constructed in accordance with a preferred embodiment of the present invention . as indicated above , the present seat cover 10 can easily alternate between one - piece and two - piece configurations for accommodating both rear and forward facing child safety chairs 12 , 14 . as will be come more apparent infra , this ability to transition between such configurations helps prevent a vehicular seat 16 such as a car seat from being damaged by accidental soiling or permanent compressions caused by the weight - bearing child safety chairs 12 , 14 . it is recognized herein that the present seat cover 10 may be utilized with other types of seats other than vehicular seats 16 . referring more particularly to fig1 and 4 , the seat cover 10 of the present invention is comprised of a lower protective member 18 and an upper protective member 20 . although those figures specifically show the lower and upper protective members 18 , 20 as being generally rectangular , it will be recognized by one of ordinary skill in the art that any shapes , configurations , sizes and / or geometries that can substantially accommodate the safety chair 12 or 14 thereupon are contemplated herein . additionally , the lower and upper protective member 18 , 20 may provide a variety forms of textures . however , it is preferred that the lower and upper protective members 18 , 20 are each fabricated from a rigid or semi - rigid material that additionally possesses tactile frictionally grip properties , and / or provides at least some degree of cushioning to , the child safety chair 12 or 14 . an exemplary material for this purpose is a polymer , foamed polymer and / or foam rubber , but other foamed polymer and / or materials are expressly contemplated herein . optionally , a washable protective cover 22 such as the one made of a nylon fabric may encapsulate the lower and upper protective members 18 , 20 so as to protect their materials from being soiled by a spillage for example . referring now to fig2 only , the lower protective member 18 is adapted to be disposed upon a seating portion 24 of the vehicular seat 16 . the lower protective member 18 accommodates a rearward - facing safety chair 12 by itself as it is only the chair &# 39 ; s base section 26 which contacts and thus applies weight to the seating portion 24 . by being placed between the safety chair 12 and the seating portion 24 , the lower protective member 18 operates to more uniformly distribute the chair weight and infant weight across the surface area of the seating portion 24 . hence , the risk of permanent compression damage to the seating portion 24 is significantly mitigated . the lower protective member 18 preferably includes a lower peripheral edge 28 which defines the outer boundaries thereof . the lower peripheral edge 28 is generally formed by a lower forward edge 30 ( disposed away from the upper protective member 20 ), a lower rear edge 32 ( disposed toward the upper member 20 ) and two lower side edges 34 interconnecting them . although not mandatory , the lower peripheral edge 28 forms a ridge - like configuration 36 substantially therearound ( i . e . except its lower forward edge 30 ). however , an alternate configuration forms the ridge 36 around the entirety of the lower peripheral edge 28 . the ridge 36 may be integrally having various heights with the lower protective member 18 . alternatively , an elongate strip 38 may be selectively extended around the lower peripheral edge 28 to form the desired ridge 36 . in this latter embodiment , such strip 38 is preferably constructed from a rigid or semi - rigid material ( e . g ., polymer on rubber ) so that the configuration of a ridge 36 can be sustained irrespective of various pressures impacting the same . by providing this ridge 36 , any spills such as spilled drinks or diaper leaks originating from the child safety chair 12 or 14 can be contained within the boundary set thereby to prevent them from flowing out and soiling any part of the seat 16 and / or vehicular interior . optionally , the lower protective member 18 may have at least one storage pocket 40 which may be extended from its lower forward edge 30 . the pocket ( s ) 40 may be any type of pocket which can adequately hold various items ( e . g ., baby bottles , toys , etc .) therein . one example of such pocket may be a mesh pocket which defines from one to any number of sufficiently deepened pouches . the pocket ( s ) 40 may be remarkably mounted to the lower forward edge 30 in any conventional manner such as using hook - and - loop or fasteners and / or snaps or zippers . furthermore , the lower protective member 18 may optionally include at least one folding line 42 which extends between the two lower side edges 34 . this folding line ( s ) 42 allows the lower protective member 18 to be folded so as to facilitate carrying thereof when it is not in use and further better accommodate any curvature the seat portion 24 . referring now to fig1 , 3 and 4 , the upper protective member 20 is configured to be disposed against a seat - back portion 44 of the vehicular seat 16 . the upper protective member 20 is used in combination with the lower protective member 18 so that a forward - facing child safety chair 14 can be accommodated collectively thereby . the upper protective member 20 is adapted to be generally contiguous with the surface of the seat - back portion 44 . in this regard , when the child safety chair 14 is placed in the forward - face direction , the chair &# 39 ; s top section 46 further contacts and thus applies its weight thereto in addition to the chair &# 39 ; s base section 26 applying weight to the seating portion 24 . it is preferred that the upper protective member 20 can be selectively attachable with and detachable from the lower protective member 18 . by providing the upper protective member 20 when desired , the compressive force generated by the weight of the forward - facing chair 14 may be more uniformly distributed upon the entire surface area of the seat portion 44 so as to lessen the continuous impact of the chair 14 at the seat - back portion 44 . therefore , the seat - back portion 44 of the vehicular seat 16 , as well as its seating portion 24 , can be adequately protected from becoming permanently deformed by the continuous weight respectively imposed by the top and base sections 46 , 26 of the forward - facing child safety chair 14 . the upper protective member 20 has an upper peripheral edge 48 defining the outer boundaries thereof . the upper peripheral edge 48 is characterized by an upper top edge 50 ( disposed away from the lower protective member 18 ), an upper bottom edge 52 ( disposed toward the lower protective member 18 ) and two upper side edges 54 interconnecting them . the upper protective member 20 may optionally have at least one folding line 56 that can extend between the two upper side edges 54 which allows it to similarly be folded for ease of carrying and conform to the curvature of the seat portion 44 . further optional is a trimming 58 which may be extended between the upper side edges 54 through the upper top edge 50 . although this trimming 58 may be any type or form , it is preferably a nylon fabric trimming . moreover , a person of ordinary skill in the art will recognize that a variety of indicia such as company names , designs or logos may be inscribed within the upper peripheral edge 48 . as illustrated in fig4 , the upper and lower protective members can be releasibly attached to each other by preferably employing the hook - and - loop strips ( commonly called the velcro ) formed therebetween . however , one of ordinary skill in the art will realize that such releasible attachment may be accomplished via other known conventional methods ( e . g ., releasible pins , buttons , etc .). in particular , a hook strip 60 is formed adjacent the upper bottom edge 52 of the upper protective member 20 . a loop strip 62 is formed adjacent the lower rear edge 32 of the lower protective member 18 . it is easily contemplated , however , that the positioning of the hook and loop strips 60 , 62 be reversed such that the hook strip 60 is formed adjacent the lower rear edge 32 and the loop strip 62 is formed adjacent the upper bottom edge 52 . by utilizing this hook - and - loop arrangement , the upper protective member 20 can easily and conveniently be attached and detached with respect to the lower protective member 18 . in operation , the present two - stage seat cover 10 is used according to a child &# 39 ; s growth progression and accommodates a child safety chair 12 , 14 upon a vehicular seat 16 without inflicting any damage thereto . typically , a parent positions the safety chair 12 in a rearward - facing direction when his or her child is in the infant stage ( i . e ., below six months of age ). in this scenario , the lower protective member 18 is used without the upper protective member 20 and is placed upon the seating portion 24 . the rearward - facing child safety chair 12 may then be set upon the lower protective member 18 substantially within its formed ridge - like configuration 36 . by doing so , the risk of permanent compression damage to the seating portion 24 is significantly reduced as the force generated by the chair &# 39 ; s weight is more uniformly distributed by ( i . e . disbursed ) the lower protective member 18 . of course , any spillage ( i . e ., spilled drinks , diaper leakage ) coming from the child safety chair 12 or 14 will be contained within ridge 36 as it forms a vertical substantially around the lower peripheral edge 28 . as the infant matures in age and weight ( i . e ., six months up to eight years or eighty pounds in weight ), the child safety chair 14 must be turned around so that it now faces the front of the vehicle . the upper protective member 20 is placed between the chair &# 39 ; s top section 46 and the seat - back portion 44 to alleviate the weight of the forward - facing chair 14 from being directly applied to the seat - back portion 44 . to accomplish such end , the upper member &# 39 ; s hook strip 60 is releasibly attached to the lower member &# 39 ; s loop strip 62 . in this respect , weight applied to the seat - back portion 44 by the forward - facing chair 14 can be sufficiently distributed by the upper protective member 20 in order to protect against permanent compression damages . the upper protective member 20 is easily detachable for adaptation toward the rearward - facing chair 12 so that the present seat cover 10 can be reused for other infants ( e . g ., younger siblings ). additional modifications and improvements of the present invention may also be apparent to those of ordinary skill in the art . thus , the particular combination of parts described and illustrated herein is intended to represent only certain embodiments of the present invention , and is not intended to serve as limitations of alternative devices within the spirit and scope of the invention .
