Abstract

A seat cover fastening system for use in conjunction With a seat cover to be installed on a vehicle seat having a seat cushion portion and a seat back portion, with an open junction therebetween. The seat cover has a front panel which overlies the front of the seat back portion, and a lower extension extending downwardly from the front panel to fit through the junction. The seat cover fastening system includes a flexible sheet of material joined to the side and top edges of the front panel to extend about the sides and over the top of the seat back portion to the rear thereof, where the sheet of material terminates in a rear edge at the rear of the seat back portion. The rear edge is formed generally in the shape of an inverted U, and includes a channel extending along a substantial portion of the edge for receiving and holding a drawstring. A drawstring is disposed in the channel so that the ends thereof extend out respective ends of the channel. The ends of the drawstring include hooks to enable connecting the drawstring to the lower extension such as by loops attached to the lower extension or eyelets or grommets formed in the lower extension. In this manner, a uniform tension is applied to the sheet of material to pull the front panel smooth against the front of the seat back portion.

Claims

1. In a seat cover for installation on a vehicle seat having a seat cushion portion and a seat back portion, with an open junction therebetween, said seat cover having a front panel, with side and top edges, which overlies the front of the seat back portion, and a lower extension extending downwardly from the front panel to fit through the junction, said seat cover also having a top panel, with side and front edges, which overlies the top of the seat cushion portion, and a rear extension extending backwardly from the top panel to fit through the junction, underneath the lower extension, said lower extension and rear extension defining an attachment fixture means,

a seat cover fastening system comprising

a flexible sheet of material joined to the side and top edges of the front panel to extend about the sides and over the top of the seat back portion to the rear thereof, said sheet of material terminating in a rear edge at the rear of the seat back portion, and formed generally in the shape of an inverted U, said rear edge including a channel extending along a substantially portion of the edge for receiving a drawstring therein,

a drawstring disposed in the channel so that the ends of the string extend out respective ends of the channel, and

means for connecting the ends of the drawstring to the lower extension to thereby apply a substantially uniform tension to the sides and top of said sheet of material and simultaneous tension to the lower extension to pull the front panel smooth against the front of the seat back portion,

a second flexible sheet of material joined to the side and front edges of the top panel to extend over the sides and front of the seat cushion portion to the bottom thereof, said second sheet of material terminating in a bottom edge underneath the seat cushion portion, and formed generally in the shape of a U, said bottom edge including a second channel extending along a substantially portion of the edge for receiving a drawstring therein,

a second drawstring disposed in the second channel so that the ends of the second drawstring extend out respective ends of the channel, and

second means for connecting the ends of the second drawstring to the rear extension to thereby apply a substantially uniform tension to the sides and front of the second sheet of material and simultaneous tension to the rear extension to pull the top panel smooth against the top of the seat cushion portion.

2. A seat cover fastening system as claimed in claim 1 wherein said sheet second sheet are made of an elastic material.

3. A seat cover fastening system as in claim 1 wherein said connecting means comprises

hooks attached to the ends of the drawstring, and

means formed on the lower extension for receiving and holding the hooks under tension to thereby pull said sheet of material taut about the sides and over the top of the seat back portion.

4. A seat cover fastening system as in claim 3 wherein said second connecting means comprises

hooks attached to the ends of the second drawstring, and

second means formed on the rear extension for receiving and holding the hooks under tension to thereby pull said second sheet of material taut about the sides and over the front of the seat cushion portion.

5. A seat cover fastening system as in claim 4 wherein said second receiving and holding means comprise a pair of grommets formed at spaced-apart locations in said rear extension near the rear edge thereof, through with respective ends, with hooks, of the second drawstring may be threaded, and

a pair of fastening elements attached at spaced-apart locations to the bottom edge of the second sheet of material, to which respective hooks may be fastened after being threaded through the grommets in the rear extension.

6. A seat cover fastening system as in claim 5 wherein said fastening elements each comprises a loop attached to said bottom edge, and a ring secured in the loop for receiving a respective hook.

7. A seat cover fastening system as in claim 3 wherein said receiving and holding means comprise eyelets formed in said lower extension near the lower edge thereof.

8. A seat cover fastening system as in claim 3 wherein said receiving and holding means comprise loops attached to said lower extension.

9. A seat cover fastening system as in claim 1 wherein said drawstrings are elastic.

10. A seat cover fastening system as in claim 1 wherein said connecting means comprises

a pair of grommets formed at spaced-apart locations in said lower extension near the lower edge thereof, through which respective ends of the drawstrings may be threaded,

a pair of fastening elements, each attached to a respective side edge of the front panel, and

means attached to the ends of the drawstring for detachably joining the strings to respective fastening elements.

11. A seat cover fastening system as in claim 10 wherein said fastening elements each comprises a loop attached to a respective side edge of the front panel, and a ring secured in the loop, and wherein the joining means comprise hooks for hooking onto respective rings.

12. A seat cover for fitting over a vehicle seat having a seat cushion and a seat back separated by an open junction, said seat cover comprising

a seat cushion cover having a top panel, side panels and a forward panel for overlying respectively the top, sides and front of the seat cushion, and having a bottom panel extending from the lower edges of the side and forward panels underneath the seat cushion to terminate in a continuous U-shaped bottom edge, opening toward the rear of the seat cushion, said bottom edges being formed with a first duct for receiving a drawstring,

a seat back cover having a front panel, side panels and an upper panel for overlying respectively the front, sides and top of the seat back, and having a rear panel extending from the rear edges of the side and upper panels behind the seat back to terminate in a continuous inverted U-shaped rear edge, opening toward the bottom of the seat back, said rear edge being formed with a second duct for receiving a drawstring,

the lower edge of the front panel of the seat back cover and the rear edge of the top panel of the seat cushion cover being joined along a common transverse locus which lies adjacent the open junction between the seat cushion and seat back when the seat cover is fitted over the vehicle seat,
