Claim 1
Independent Claim
241 words
For use on a motor vehicle seat having a seat cushion and backrest extending upward from the seat cushion, a seat cover for single use in car workshops and for protecting the motor vehicle seat, the seat cover being made from a double-layered piece of plastic film the seat cover comprising: a front film having an outside surface, an inside surface, a top edge and longitudinal edges, the front film adapted to extend and protect a top portion of the seat cushion and a portion of the backrest; a rear film comprising a separate piece from the front film, the rear film having a top edge, longitudinal edges, an inside surface and an outside surface, the rear film top edge connected with the front film top edge by a transverse welding and portions of the longitudinal edges of the front film and the rear film are connected to each other by a longitudinal welding to form a first pocket for the reception of at least a part of the backrest; wherein the front film consists of coextruded plastic material having a high friction coefficient on the front film inside surface and a comparatively low friction coefficient on the front film outside surface, wherein the front film inside surface is facing the rear film inside surface; and wherein at least a portion of the rear film inside surface has a comparatively low friction coefficient with respect to the front film outside surface.

For use on a motor vehicle seat having a seat cushion and backrest extending upward from the seat cushion, a seat cover for single use in car workshops and for protecting the motor vehicle seat, the seat cover being made from a double-layered piece of plastic film the seat cover comprising: a front film having an outside surface, an inside surface, a top edge and longitudinal edges, the front film adapted to extend and protect a top portion of the seat cushion and a portion of the backrest; a rear film comprising a separate piece from the front film, the rear film having a top edge, longitudinal edges, an inside surface and an outside surface, the rear film top edge connected with the front film top edge by a transverse welding and portions of the longitudinal edges of the front film and the rear film are connected to each other by a longitudinal welding to form a first pocket for the reception of at least a part of the backrest; wherein the front film consists of coextruded plastic material having a high friction coefficient on the front film inside surface and a comparatively low friction coefficient on the front film outside surface, wherein the front film inside surface is facing the rear film inside surface; and wherein at least a portion of the rear film inside surface has a comparatively low friction coefficient with respect to the front film outside surface.
Claim 3
Dependent Claim
27 words
The seat cover of claim 1, wherein the rear film inside and outside surfaces have a low friction coefficient with respect to the front film outside surface.
Claim 4
Dependent Claim
40 words
The seat cover of claim 1, wherein the front film consists of a three-layered coextruded plastic material having an intermediate layer sandwiched by first and second outside layers, in which the intermediate film serves to improve the ultimate tensile strength.
Claim 5
Dependent Claim
