Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
228 words
An easily removable temporary plastic seat cover for protecting a new automobile-type vehicle seat having seating and backrest portions, wherein a frame on the underside of the seat is first covered with the seat cover and subsequently secured to a support means in bearing engagement with at least one portion thereof, the seat cover comprising a bag that fits over the front of the seat and extends over the top of the seat and under the frame, the seat cover including at least one opening in the underside thereof that surrounds the portion of the frame that is in bearing engagement with the support means, such that the seat cover is not pinched between the seat frame and support means when they are secured together, the seat cover being tearable to remove the seat cover from the seat, the opening permitting removal of the entire seat cover, without a portion of the seat cover being retained in the area of bearing engagement between the seat frame and the support means, the seat cover being formed of a co-extruded plastic material wherein inside and outside surface layers are formed of two different plastic materials having different coefficients of friction, the ouside surface being relatively slippery compared with the inside surface, the outside surface layer being formed of high-density polyethylene and inside surface layer being formed of linear low-density polyethylene.
Claim 2
Dependent Claim
228 words

Claim 3
Dependent Claim
48 words
A temporary plastic seat cover according to claim 1 wherein the coefficient of friction of the inside surface is about 0.3 or greater and the coefficient of friction of the outside surface is 0.25 or less, and the differences between the coefficients of friction are at least 0.1.
Claim 4
Dependent Claim
37 words
A temporary plastic seat cover according to claim 1 wherein the coefficient of friction of the inside surface is about 0.5 to 0.7 and the coefficient of friction of the outside surface is about 0.2 or less.

Dependent Claim
18 words
A temporary plastic seat cover according to claim 4 wherein the inside surface layer comprises low density polyethylene.
Claim 10
Dependent Claim
19 words
A temporary plastic seat cover according to claim 7 wherein the inside surface layer comprises linear low density polyethylene.
Claim 11
Dependent Claim
134 words
A temporary plastic seat cover according to claim 4 wherein the seat is fastened to a support on the floor of the vehicle and the seat bears on the support at the point of attachment but is spaced apart from the support at other portions of the seat, the seat cover fitting over a front edge of the seat prior to installation in the vehicle and extending over upper and lower sides of the seating portion, the seat cover having at least one opening therein that surrounds the area where the seat contacts the support, such that the seat cover is not pinched between the support and the seat, the seat cover being manually tearable for easy removal of the seat cover without leaving parts of the seat cover between the support and seat.
Claim 12
Dependent Claim
46 words
A temporary plastic set cover according to claim 9 wherein the seat cover has a line of weakened tensile strength extending from an edge of the seat cover to the opening so as to facilitate tearing of the seat cover to remove it from the seat.
