A retractable seat cover for providing temporary protection to a seat, such as an automotive seat or piece of furniture, includes a housing, a roll of fabric, a retraction mechanism, and a strap. The housing has a slit for enabling the fabric to be extended from the housing through the slit or be retracted into the housing through the slit. The fabric, which may be waterproof, moisture repellent and/or have anti-bacterial properties for providing additional protection to the seat, is used to cover the upholstery of the seat. The retraction mechanism includes a spring roller mechanism and a button for controlling rotation of the roll of fabric. The strap is attached to a top portion of the fabric and is used to secure the seat cover to the seat, such as a headrest of an automobile or the top of a piece of furniture.

A female coupler as set forth in claim 2, wherein the annular relief functions as a catch for rear side wall of the annular groove when the wiper seal is rotated thereby to aid in holding the wiper seal in the annular groove when a surge of high pressure fluid passes from the main cavity to the back side of the piston. 7. A female coupler as set forth in claim 6, wherein the radially inner edge of the rear side wall of the annular groove is offset from the radially inner edge of the front side wall of the annular groove by at least about the thickness of the web. 8. A female coupler as set forth in claim 1, wherein the wiper seal is radially elongated in cross-section. 9. A female coupler as set forth in claim 1, wherein the annular relief functions as a catch for rear side wall of the annular groove when the wiper seal is rotated thereby to aid in holding the wiper seal in the annular groove when a surge of high pressure fluid passes from the main cavity to the back side of the piston. 10. A female coupler, comprising: a housing having an internal bore with an open forward end adapted to receive a male coupler, and a flow port for supplying pressurized fluid to the internal bore; a tubular spacer inserted in the housing bore and forming therewith an outer flow passage isolated from an internal bore in the spacer, the spacer having an open forward end and a rear end wall closing the rear end of the spacer; a valve body axially slidable in the spacer bore, the valve body including a main cavity opening to the forward end of the housing bore and a peripheral inlet passage through the valve body communicating the outer flow passage with the main cavity, the valve body and the rear end wall of the spacer defining therebetween a vent cavity; and wherein the spacer has an annular land press-fitted in the housing bore and located axially between the outer flow passage and a vent chamber within the housing bore, which vent chamber communicates with the vent cavity via a passage in the spacer, and the annular land has an annular groove retaining an annular seal for sealing against the side wall of the housing bore to prevent leakage flow from the outer flow passage to the vent chamber. 11. A female coupler as set forth in claim 10, wherein the housing has a rear end wall including a counterbore opening to the housing bore, and the rear end wall of the spacer has an axially rearwardly extending post press-fitted in the counterbore. 12. A female coupler as set forth in claim 11, wherein the annular land and the post are coaxial. 13. A female coupler as set forth in claim 11, wherein the post includes an annular groove retaining an annular seal for sealing against the housing. 14. A female coupler as set forth in claim 13, wherein the rear end wall of the housing includes the flow port, the flow port is circumscribed by the annular seal retained in the annular groove in the post, and the rear wall of the spacer includes a passage communicating the flow port with the outer flow passage. 15. A female coupler as set forth in claim 14, wherein the interface between an axial end face of the post and the bottom of the counterbore is vented to the vent chamber. 16. A female coupler as set forth in claim 10, further comprising a centering spring retained in an annular recess in the radially outer surface of the valve body, and further between a shoulder at the front end of the housing and a front end face of the spacer. 17. A female coupler as set forth in claim 15, wherein the housing includes a tubular rear end portion and a tubular front end portion screwed into the rear end portion, and the front end housing portion includes the shoulder. 18. A female coupler as set forth in claim 10, wherein the housing includes a tubular rear end portion and a tubular front end portion screwed into the rear end portion, and the front end portion is axially spaced apart from the spacer. 19. A female coupler, comprising: a housing having an internal bore with an open forward end adapted to receive a male coupler, and a flow port for supplying pressurized fluid to the internal bore; a valve body disposed in the bore and axially moveable in the housing, the valve body including a main cavity opening to the forward end of the housing bore, a peripheral inlet passage through the valve body communicating with the main cavity, and an interior valve seat forwardly of the inlet passage; a piston axially movable in the valve body and including a central bore; a poppet valve slidably guided in the central bore of the piston, the poppet including a valve portion disposed in the main cavity of the valve body, a forward projection adapted to engage a check valve in the male coupler when the male coupler is received in the housing, and a rearward tubular portion radially stepped to form a annular shoulder portion joining a front wall section to a rear wall section; and at least one coil spring for forwardly biasing the poppet valve against the valve seat to normally prevent fluid flow through the valve body, a forward portion of the coil spring being radially constrained by a radially inner surface of the front wall section of the rearward portion of the poppet valve, the rear wall section having a radially inner surface spaced radially outwardly from the coil spring to form interiorly of the poppet valve a flow path for pressurized fluid passing form the main cavity to a back side of the piston, and the annular shoulder portion including one or more orifices for connecting the main cavity to the flow path without any interference of the coil spring. 20. A female coupler as set forth in claim 18, wherein the annular shoulder portion is sloped relative to the axis of the poppet valve. 21. A female coupler comprising: a housing having an internal bore with an open forward end adapted to receive a male coupler, a flow port for supplying pressurized fluid to the internal bore, and a locking collar chamber at the open forward end; a valve body disposed in the bore and axially moveable in the housing, the valve body including a main cavity opening to the forward end of the housing bore, and a peripheral inlet passage through the valve body communicating with the main cavity, and a tubular front end socket portion including at least one radial bore which retains a locking element for radially inward and outward movement; a locking collar axially movable in the collar chamber between locking and release positions, the collar in its locking position being operative to hold the locking element at a locking position such that it protrudes radially inwardly of a radially inner surface of the socket portion for engaging a locking groove in the male coupler, and the collar in its release position enabling radial outward movement of the locking element for disengagement from the locking groove in the male coupler; a coil spring circumscribing the locking collar for biasing the locking collar against a stop; a retainer at the front end of the locking collar chamber; and an annular protection shield interposed between a front end of the coil spring and the retainer to hold the coil spring in the collar chamber, and the protection shield having a radially inner edge adjacent and surrounding the socket portion of the valve body, thereby to prevent debris from entering the locking collar chamber.
