Description:

BACKGROUND OF THE INVENTION

[0001] The present invention relates to automotive seats and more particularly to a modular seat that may be installed on either the driver's side or the passenger's side.

[0002] U.S. Pat. No. 4,630,866 teaches a reclining unit that controls the reclining angle of the backrest of a seat. The occupant of the seat can unlock the locking mechanism by operating a button that acts through a pull cable on the locking mechanism.

[0003] U.S. Pat. No. 4,887,864 teaches a reclining unit that includes a recliner assembly and a lever assembly that is remotely mounted. The lever assembly may either be integrated into the upholstery in the region of one of the bolsters or be separately mounted within the dashboard or a center console of the vehicle. A cable extends from the lever assembly to operate the recliner assembly. An occupant may accordingly adjust the backrest position relative the bench-seat without undue effort. The modularly arranged seat frameworks support custom upholstered seat cushions and are mountable in a variety of makes, models and years of automobiles.

[0004] U.S. Pat. No. 4,765,681 teaches a seat adjustable recliner hinge assembly that employs toothed sector, pivoted toothed pawl and retractable pivoted eccentric cam that is resiliently urged to pawl engaging sector retaining seat back-adjusted position. A remote lever actuated flexible cable release connection for the cam applies cable tension at an effective cam actuating radial moment arm relative to the cam pivot in a direction opposite to the resilient biasing.

[0005] U.S. Pat. No. 4,872,726 teaches a ratchet recliner that is used for automotive vehicle seats. The ratchet recliner has a remote hand lever release feature.

[0006] U.S. Pat. No. 4,223,947 teaches a ratchet recliner that includes a pivoted cam for locking a toothed pawl in engagement with a toothed sector for any adjusted position of the seat back hinge bracket, with a hand lever provided for direct actuation of the pivoted cam.

[0007] U.S. Pat. No. 6,267,443 teaches a reclining seat that has a backrest adjustable to any desired angle. The backrest is connected to the rear of the seat.

[0008] U.S. Pat. No. 4,653,807 teaches an adjustable seat assembly that includes a seat bottom and a seat back, a reclining mechanism for connecting the seat back to the seat bottom for the adjustment of the tilt of the seat back relative to the seat bottom.

[0009] Japanese Laid-open Utility Model Publication No. 57-48139, published on Mar. 17, 1982, discloses an adjustable seat assembly that is provided with reclining mechanism and slide mechanisms.

[0010] Japanese Laid-open Utility Model Publication No. 57-109936, published Jul. 7, 1982, discloses an adjustable seat assembly.

[0011] U.S. Pat. No. 5,803,529 teaches a removable vehicle top assembly for use with a Jeep-type vehicle for attaching a combination hard top and flexible soft-top cover. A first hard top cover is fastened over a forward passenger area of the vehicle.

[0012] U.S. Pat. No. 4,746,163 teaches a combination removable panel-convertible top system that includes a rear convertible frame section and a separately attachable section which extends between the rear section and an edge of the windshield to substantially overlay the forward seating area of the vehicle. While providing a convenient and useful convertible top assembly for a passenger-type vehicle, the device is not readily adaptable for use with other vehicle types, specifically Jeep design vehicles.

[0013] U.S. Pat. No. 4,850,634 teaches a folding top for cross-country vehicles which includes a number of interconnected tubular members which are selectively folded and unfolded to create a skeletal structure over which is attached a covering material. Its disadvantages include its relative complexity of design that increases the likelihood of a material failure over extended use. A further disadvantage of the folding structure is the inability to use the device with a Jeep-type vehicle that customarily utilizes roll bar protectors extending throughout the passenger and storage compartments of the vehicle, the existence of roll bars preventing the necessary range of motion. The standard Jeep vehicle includes forwardly directed passenger and rearwardly directed storage compartments. Two roll bars extend throughout the passenger and storage areas and provide protection the vehicle's occupants in the event of a rollover. Currently, two different Jeep top covers are available for use and include a soft top cover for warm weather driving conditions and a heavier hard top cover for winter driving. The disadvantages of owning two tops for use with the vehicle include the increased cost of owning more than one top, the need for storage of the unused top and the effort which must be expended in disengaging one of the tops and attaching the other.

[0014] U.S. Pat. No. 6,076,889 teaches a reclining car seat hinge for a chair.

[0015] The applicant hereby incorporates the above referenced patents into his application.
